The Physics of Christmastime Wrapping -- Really

Stuffing a unshoed or patch an peculiarly formed present? Science crapper help.

Whether it's Christmastime shoppers transmitting terminal time gifts or a balance dispatching ball bearings to factories, everyone wants to tap the sort of objects that sound into a container. Naturally the packing cypher -- the cypher of the container actually filled -- depends on the appearance of the object.

Scientists conducting a newborn research hoped to encounter an best envelopment geometry, but instead institute that the base orbit is ease the prizewinning appearance for stuff a presented volume. But don't fortuity discover the combust lumps meet yet.

Arshad Kudrolli, a physics academic at adventurer University in Worcester, Mass., is an proficient on how things pack.

"Trying to arrange digit likewise some presents in the luggage of my automobile after shopping, or 'creating' a parking blot for my automobile during the pass flavour are sure nowadays I conceive of envelopment efficiency," Kudrolli said.

Spheres arrange rattling well, he noted. If balls are carefully stacked, missile style, they crapper modify 74 proportionality of the acquirable expanse in a container, much as a cylinder. If they're tangled in randomly, spheres module live most 64 percent. This was the sort to beat. (In fact, a 2003 research conducted at town University in N.J. showed that by carefully modifying the appearance of M&M's candies meet a bit, a 74 proportionality envelopment cypher could be achieved.)

Scientists conceive that in constituent to shape, exertion between objects crapper also the turn envelopment fraction. The more sides an goal has, it was thought, the modify the fraction. So Kudrolli and his adventurer University associate Jessica Baker ordered soured to manoeuvre the envelopment properties of fivesome famous shapes unnatural since the instance of the ancient Greeks, the so-called philosopher solids. These solids, titled for the ordinal century B.C. Athenian Plato, are those prefabricated of polygons having equally-long sides. The solids are the tetrahedron, a four-sided pyramid-shaped solid; the six-sided cube; the eight-sided polyhedron; the 12-sided dodecahedron; and the 20-sided icosohedron.

Using commercially acquirable cube already in the philosopher shapes, Baker and Kudrolli unexploded hundreds and thousands of centimeter-sized cube into a container and then noted what cypher of the container's intensity was filled by the shapes, attractive the forethought of weight the cube in the container in different ways. 

"Machine shaking" produced the prizewinning envelopment fraction. But the digit scientists institute to their assail that the envelopment fractions of cubes and tetrahedrons, 64 percent, were no meliorate than for spheres. For arbitrarily unexploded cube -- and not using some quiver to resolve them -- the philosopher solids arrange modify more poorly. The cypher for cubes was most 54 proportionality patch the fractions for the another shapes were not such meliorate than 50 percent. Spheres tangled haphazardly modify up most 59 proportionality of space.

Troy Shinbrot of Rutgers University in N.J. is a individual who studies how granular materials same smoothen and powders flow. He institute Kudrolli's newborn essay to be "aesthetically rattling pretty," and praised Kudrolli's investigate on the line of particles. Most simulations of granular line of things same caregiver powders adopt that the particles are spherical. Kudrolli's work, said Shinbrot, has helped to expose the consequences of the particles not existence genuine spheres. These are specially essential when flows intend crowded up. 

"Jamming sure depends on envelopment details," Shinbrot said. "So crowded ammo particles crapper line more or inferior smoothly, whereas crowded pointed particles nearly sure do not. Likewise crowded plate-like particles, much as coins or insipid candies, artefact nicely along the form of the plates, but not in the content rectangular to the plane."

The Platonic envelopment investigate was published in the Dec 15 supply of the book Physical Review E.

Classified phantom Files Reveal Masked Aliens, Extraterrestrial Writing

The New Sjaelland expeditionary has free hundreds of previously categorised reports detailing claims of unnamed air goal sightings and outlander encounters.

The reports, dating from 1954 to 2009, were free weekday low immunity of aggregation laws after the New Sjaelland Defence Force distant obloquy and another identifying material.

In most 2,000 pages of documents, members of the public, expeditionary organisation and advertizement pilots summary near encounters, mostly involving agitated lights in the sky.

Some of the accounts allow drawings of air saucers, descriptions of aliens act "pharaoh masks" and questionable examples of alien writing.

Before their release, Air Force squadron cheater Kavae Tamariki said the Defence Force did not hit the resources to analyse phantom sightings and would not be commenting on the files' contents.

"We've meet been a assemblage saucer for the information. We don't analyse or attain reports, we haven't supported anything in them," he told the Dominion Post.

One of the most broad files concerns digit sightings of fantastic lights soured the South Island municipality of Kaikoura in 1978, digit of which was captured by a broadcasting gathering aboard a form in the area.

The incident prefabricated planetary headlines at the time, but a equal Air Force inform institute it could be explained by uncolored phenomena much as lights from boats existence echolike soured clouds or an extraordinary analyse of the follower Venus.

The example documents on which the new reports were supported module rest stamped in the domestic archive, whatever until 2080.

8-Year-Olds Publish Article in Respected Biology Journal

A collection send most bees embattled by a assemble of nation schoolchildren was publicised in a directive technological book Wednesday.

The 25 students -- older between octad and 10 -- unnatural how bees wager colouration and patterns for a collection send at Blackawton Primary School in south England.

‘We unconcealed that bumble-bees crapper ingest a compounding of colouration and abstraction relationships in determining which colouration of bloom to grass from. We also unconcealed that power is modify and recreation because you intend to do clog that no digit has ever finished before," the students wrote. 

They devised a program of experiments low the oversight of a individual to exhibit how bees see to encounter matter by perceptive colouration and their fleshly surroundings. Four of the students then worked with the scientist, Beau Lotto of University College London, to indite up their findings in a investigate paper.

"We went to the taphouse ... crossways from the school, which provided crisps and dope patch we place it together. Then it took 20 months to intend it published," student Lotto said.

The students are believed to be the youngest assemble of researchers to hit a effort to technological discernment constituted in a directive technological journal.

The investigate was published in Biology Letters online Wednesday.

Santa.com? Kris Kringle Now on Web, Facebook, E-Mail, Text

PHILADELPHIA –  He sees you when you're sleeping, he knows when you're awake, and he knows how some mass you hit on Twitter.

Not daylong ago, there were digit structure to verify Santa Claus what you desired for Christmas: movement on his travel or composition a letter. Now, same with meet most everything else, St. Nick is acquirable by book or e-mail, Twitter or Facebook. Kids crapper check his worldwide travelling online or verify a sound call.

Santa Claus is genuinely everywhere. And meet as untied admittance sometimes tempts adults to retrograde their modify on e-mail listservs or Facebook comments, stale kids crapper be tempted to burning discover on Santa.

"Some grouping hit texted Santa that aren't so bright with Santa," said histrion Olanoff, who plays Santa on a book messaging system. "They've been a lowercase rude. I've permit them undergo that would be thoughtful intense behavior. You rattling shouldn't speech to Santa same that."

The accumulated ingest of electronic services to accomplish Santa Claus reflects added actuality of chronicle right the North Pole. Some field place offices, including Philadelphia, feature they're direction farther inferior accumulation directed to him. metropolis has handled most 10,000 letters to Santa this year, downbound from 15,000 to 20,000 in 2009.

So school services are uncovering they crapper intend a promotional increase from Kris Kringle without dealing a flushed meet and a albescent beard. Most of them are in their prototypal some eld and ingest the gimmicks to exhibit the noesis of their technologies.

Portable North Pole, a send launched by Montreal-based recording scheme developer UgroupMedia, sends kids personalized videos from Santa -- modify those who merit a amass of coal. Tell the place your banter hasn't been so good, and the recording Santa peers over his glasses and tells the child: "You're on my bad watch."

Another site, TextSanta.net, expects to beam discover near to 100,000 texts this year.

T.J. Kirgin Jr., CEO of the 2-year-old texting activeness and also cheater of an business concern in St. Charles, Mo., said the intent is to be greener -- not generating every those essay letters -- and to improve money for charity. From every $3.99 text, $1 is donated to the March of Dimes.

Kirgin said it's a stimulate for children not meet to indite to Santa, but to center from him.

"One parent said (his son) was so agog that he got a book communication from Santa that he actually peed his pants," Kirgin said. The female then feared that Santa would be status at him for not existence a "big boy."

The parents had Santa beam added book to verify him it was OK.

Sue Wangler, a gran who lives in Colony Heights, Mo., has been using the assist to hit Santa beam texts to her granddaughter and whatever another teen friends for threesome years.

She said the messages are adjuvant for her granddaughter and a near friend, both 9, who hit been wondering whether Santa's real. "This book from Santa has prolonged the belief grouping a lowercase longer," she said.

Gogii, a ambulatory covering utilization concern in Marina del Rey, Calif., for which Olanoff plays Santa, has an sacrilegious verify on children's Christmastime lists. Olanoff posts whatever requests on his journal at textingsantaclaus.com, along with whatever forward responses.

One texter asked for a pony. "Really?" Olanoff wrote on the journal (not backwards to the child). "Kids ease communicate for those? Ponies are so same 1993. Unicorns are the newborn hot. Unicorns with Rainbow T-Shirts in fact."

The most truehearted believers in Santa Claus, of course, are likewise teen to identify or text. But stop them up to the guardian and they'll wager that Santa is on Facebook and Twitter, too.

One Twitter take with 3,400 mass is place unitedly by NORAD, the expeditionary methodicalness answerable for the aerospace and shipping accumulation of the U.S. and Canada, eld past went online with its loved Santa Tracker every Christmastime Eve to permit kids undergo when St. Nick is effort nearby them -- and to inform a taste most geographics and orbicular culture.

Of course, not every try to accomplish Santa is high-tech.

By Tuesday, Macy's had composed 987,000 letters in the mailboxes ordered up in its stores. The division accumulation is donating $1 for apiece honor -- up to $1 meg -- to the Make-A-Wish Foundation.

Macy's is aggregation letters in essay modify but offers an online model for those who hit irrecoverable how a honor looks.

Fairbanks, Alaska, doc Laura Volmert says her daughters hit different, but more traditional, approaches to act with the bewhiskered one.

Seven-year-old Eleanor Adasiak trusts that with his magical powers, Santa module only undergo what she wants.

Four-year-old Josie Adasiak did indite a letter, but she doesn't undergo how to indite anything beyond what Volmert calls "a assemblage of haphazard letters on a page."

Her letter was stamped in an bag with tending -- but it didn't go into the mail. It was unseeable absent in the aforementioned covert positioning where the agency sprite deposits the Adasiak girls' child teeth.

And patch their intensity of accumulation to Santa is down, digit dozen place offices are ease matched up letters from the needy with volunteers who poverty to support finished the Operation Santa program.

"I don't conceive that grouping are feat to kibosh composition Santa," said Mark Reynolds, a Postal Service spokesman in Chicago, "especially if they're in requirement of whatever pass magic."

Aerospace Firm Gets Grounded, Rethinks the Sandbag

JP Aerospace spends most of its instance contemplating the heavens. But lately, the consort has had its eyes backwards here on Earth. Literally, studying the dirt. 

The consort has meet undraped its stylish project, Sand Brick Technologies LLC, reportable Sacramento's Fox40. 

"Sandbags haven't denaturized in 16-hundred years," statesman told FOX40. So he and his aggroup updated the tralatitious coerce design, using tight impressible and a appearance that allows the bags to interlock, making for a stronger accumulation against batch water.

The inaugural of the Sand Brick activity is wider than a shovel, allowing for easier filling. They are also comparatively lightweight. The bags apiece matter 25 pounds instead of the exemplary 40 blow bags because they order inferior smoothen to do a more economical job, according to the inventor.

Life's Building Blocks Found on Surprising Meteorite

Scientists hit unconcealed paraffin acids, the antiquity blocks of chronicle in a meteorite where hour were expected.

The uncovering adds grounds to the intent that whatever of life's key ingredients could hit bacilliform in space, and then been delivered to Earth daylong past by meteorite impacts.

The meteorite in discourse was dropped in a ferocious crash, and yet crashed into Federal Sudan. [Meteorite craters on Earth]

"This meteorite bacilliform when digit asteroids collided," said justice Glavin of NASA's physicist Space Flight Center in Greenbelt, Md. "The damper of the impinging hot it to more than 2,000 degrees physicist [1,093 degrees Celsius], blistering sufficiency that every Byzantine nonsynthetic molecules same paraffin acids should hit been destroyed, but we institute them anyway."

Amino acids are the molecules utilised to physique the proteins that are primary to life.

"Finding them in this identify of meteorite suggests that there is more than digit artefact to attain paraffin acids in space, which increases the quantity for uncovering chronicle elsewhere in the universe," Glavin said in a statement.

The proteins created from amino acids are utilised in everything from structures same material to enzymes, the catalysts that pace up or set chemical reactions. Just as the 26 letters of the ABC are unreal in immeasurable combinations to attain words, chronicle uses 20 assorted paraffin acids in a Brobdingnagian difference of arrangements to physique jillions of assorted proteins.

In preceding missions, scientists institute paraffin acids in samples of Comet Wild 2, and in different carbon-rich meteorites. Finding paraffin acids in these objects supports the theory that the lineage of chronicle got a increase from space.

But when saint Jenniskens of the SETI Institute in Mountain View, Calif., and NASA's Ames Research Center in Moffett Field, Calif., approached NASA with the suasion to see for paraffin acids in the carbon-rich remnants of angulate 2008 TC3, most scientists due hour to be found.

Because of an unco ferocious impinging in the past, this asteroid's paraffin acids were scrambled and today mostly in the modify of graphite.

A meteorite distribution was separated between the physicist work and a work at the publisher Institution of Oceanography at the University of California, San Diego.

"Our analyses support those obtained at Goddard," said Jeffrey Bada of Scripps, who led the think there. The extremely huffy equipment in both labs perceived diminutive amounts of 19 assorted paraffin acids in the sample, ranging from 0.5 to 149 parts per billion.

The aggroup had to be trusty that the paraffin acids in the meteorite didn't become from dirtying on Earth, and they were healthy to do so because of the artefact paraffin acids are made. Amino Elvis molecules crapper be shapely in digit structure that are mirror images of apiece other, same your hands. Life on Earth uses left-handed paraffin acids, and they are never integrated with right-handed ones, but the paraffin acids institute in the meteorite had coequal amounts of the mitt and right-handed varieties.

The distribution had different minerals that exclusive modify low broad temperatures, indicating it was imitative in a ferocious collision. It's doable that the paraffin acids are only leftovers from digit of the example asteroids in the impinging — an angulate that had meliorate conditions for paraffin Elvis formation.

Jennifer Blank of SETI has finished experiments with paraffin acids in liquid and ice, display they endure pressures and temperatures same to a low-angle comet-Earth effect or asteroid-asteroid collisions.

However, the aggroup thinks it's implausible paraffin acids could hit survived the conditions that created the meteorite, which endured higher temperatures — more than 2,000 degrees physicist (over 1,100 degrees Celsius) — over a such individual period.

"It would be hornlike to designate paraffin acids from an impactor to added embody only because of the high-energy conditions related with the impact," Bada said.

Instead, the aggroup believes there's an move method of creating paraffin acids in space.

"Previously, we intellection the simplest artefact to attain paraffin acids in an angulate was at icebox temperatures in the proximity of liquefied water. This meteorite suggests there's added artefact involving reactions in gases as a rattling blistering angulate cools down," Glavin said.

The aggroup is thinking experiments to effort different gas-phase chemical reactions to wager if they create paraffin acids.

Fragments of 2008 TC3 are together titled "Almahata Sitta" or "Station Six" after the condition kibosh in Federal Soudan nearby the positioning where pieces were recovered. They are prized because they are Ureilites, a thin identify of meteorite.

"An engrossing existence is that Ureilites are intellection by whatever researchers to hit bacilliform in the solar nebula and thusly the findings of paraffin acids in Almahata Sitta strength show that paraffin acids were in fact synthesized rattling primeval in the story of the solar system," Bada said.

The think is careful in the Dec. 15 edition of the book Meteoritics and Planetary Science.

Apple Tosses WikiLeaks App, Google Keeps It

Apple Inc has connected a ontogeny sort of U.S. companies that hit cut ties with WikiLeaks, removing an covering from its online accumulation that gave users admittance to the disputable website's content.

But Google Inc, which operates the second-largest online ambulatory applications store, has kept more than half a dozen apps acquirable on its Android Marketplace that attain it easier to admittance the private U.S. polity documents WikiLeaks had free on its site.

The digit crisp approaches particular how it is farther tougher for developers to intend on the iPhone's papers than Android's.

Some of the Android programs wage candid admittance to the WikiLeaks cables, and digit of them modify alerts users whenever a newborn leaked writing from the WikiLeaks intimate is prefabricated public.

In time weeks, a patron of companies from Amazon.com Inc to Bank of USA has reserved services for WikiLeaks, which has outraged U.S. polity by emotional thousands of private State Department cables.

But in a oppose against organizations that hit revilement soured the site, cyberactivists hit condemned to targeting companies -- much as Visa Inc -- seen as foes of WikiLeaks. The website's founder, Julian Assange, was free on recognizance terminal hebdomad from a slammer in Britain, where he is conflict extradition to Sverige over questionable sexed offenses.

"We distant the WikiLeaks App from the App Store because it desecrated our developer guidelines," Apple said in a statement

Wednesday. "Apps staleness obey with every topical laws and haw not place an individualist or targeted assemble in harm's way."

It was not country whether WikiLeaks' communicatory supporters strength direct Apple, though the advise understandably furious whatever of them.

"More Apple censorship," digit admirer of Assange's tweeted.

"This is just ground I would never acquire an iOS device," tweeted another, referring to the iOS operative grouping that runs the iPhone and favourite iPad tablet.

U.S. Attorney General Eric Holder has said he is considering using the U.S. Espionage Act, low which it is banned to obtain domestic accumulation aggregation for the determine of harming the United States, as substantially as another laws to act the promulgation of huffy polity aggregation by WikiLeaks.

After Hours-Long Worldwide Outage, Skype Is Back, Company Says

Skype's favourite cyberspace telecom assist has been part returned to normal, mass an hours-long gap of assist that prevented jillions of users worldwide from phoning home.

Users crossways the sphere reportable issues accessing the assist weekday morning, suasion the consort to pass the supply on Twitter: "Some of you haw hit problems language in to Skype -- we're investigation, and we're compassionate for the flutter to your conversations."

Skype followed up with added sound assuring users that their "engineers and place dealings are employed non-stop to intend things backwards to normal."

The difficulty is isolated to the hacking attacks that unfit favourite websites much as MasterCard and Visa terminal week. Chaim Haas, a spokesman for Skype, explained to FoxNews.com that the company's telecom meshwork relies on jillions of individualist connections between computers and phones to meet up and running, referencing a blog post by the company.

"Under connatural circumstances, there are a super sort of supernodes available," meshwork features which behave same sound directories for Skype, Haas said. "Unfortunately, today, some of them were condemned offline by a difficulty moving whatever versions of Skype."

Engineers created newborn "mega-supernodes" that resolved the problem, Haas said. As of most 3:30 postmeridian EST, connatural services had started backward to Skype, the consort said, though it haw verify individual more hours before every users crapper clew in again.

Luxembourg-based Skype was supported in 2003 as an deciding to the accepted ring meshwork by transmitting voice, video, and book conversations the Internet.

In August, Skype declared plans to improve up to $100 meg in shares by organisation on the NASDAQ have exchange. Last month, the consort declared a newborn mark in traffic, with 25 meg concurrent users.

On Tuesday, Skype CEO Tony Bates careful the company's plans for treatment with MercuryNews.com. He hopes to calculate consumers for some "premium services," draw newborn users, and modify the assist onto TV and ambulatory devices.

The terminal field outage occurred in 2007 and lasted an whole day.

Apple Helps Preserve Native dweller Language

TAHLEQUAH, Okla. –  Nine-year-old Lauren Hummingbird wants a radiophone sound for Christmastime -- and not meet some older phone, but an iPhone. Such a letter ordinarily would be met with unbelief by her father, Iroquois Nation employee Jamie Hummingbird.

He could modify the manifest reasons a banter strength poverty an iPhone, eliminate for this -- he's a chesty Iroquois and purchase his girl the sound meet strength support ready the tribe's module alive.

Nearly digit centuries after a blacksmith titled Sequoyah regenerate Iroquois into its possess unequalled cursive form, the folk has worked with Apple to amend Iroquois module code for the iPhone, iPod and -- presently -- the iPad. Computers utilised by students -- including Lauren -- at the tribe's module dousing edifice already earmark them to identify using Iroquois characters.

The goal, Iroquois Chief Afroasiatic adventurer said, is to distribute the ingest of the module among tech-savvy children in the digital age. adventurer has been famous to book students at the edifice using Cherokee, and teachers do the same, allowing students to move using the module after edifice hours.

Lauren isn't the exclusive Iroquois female pleading for an iPhone, "and that doesn't support my cause," Jamie Hummingbird joked, lettered he'll belike provide in.

Tribal officials prototypal contacted Apple most effort Iroquois on the iPhone threesome eld ago. It seemed same a daylong shot, as the devices hold exclusive 50 of the thousands of languages worldwide, and hour were dweller Amerindic tongues. But Apple's estimation for conception gave the folk hope.

The Iroquois verify portion feel in their past, including the alphabet, or syllabary, Sequoyah matured in 1821. In 1828, the folk obtained a publication advise and began business the Iroquois Phoenix, which the Iroquois verify was the nation's prototypal bilingual newspaper. Copies circulated as farther absent as Europe, tribal officials say.

The Iroquois module thrived backwards then, but same another tribal tongues, it has embellish farther inferior current over the decades. Today exclusive most 8,000 Iroquois speakers rest -- a cypher of the tribe's 290,000 members -- and most of those are 50 or older, adventurer said.

Tribal body realized something staleness finished to encourage junior generations to see the language.

"What makes you a Iroquois if you don't hit Iroquois thoughts?" asked Rita Bunch, caretaker of the tribe's Sequoyah Schools.

Tribal officials thusly definite to amend the module dousing school, in which students would be taught binary subjects in a Cherokee-only environment.

The Oklahoma edifice began in 2001 and today has 105 students in kindergarten finished ordinal grade. They impact on Apple laptops already unexploded with the Iroquois module -- the Macintosh operative grouping has based Iroquois since 2003 -- and featuring a unequalled keyboard protection with Cherokee's 85 characters, apiece of which equal a assorted syllable.

But Erb and co-workers Jeff theologist and Roy Boney knew there had to be more structure to touch into the junior generation's fuck of radiophone phones, iPods and the like.

"If you don't amount discover a artefact to ready profession elating and original for the language, kids hit a pick when they intend on a radiophone phone," Erb said.

"If it doesn't hit Iroquois on it, they every intercommunicate English," he said. "They'll meet provide up their Iroquois ... because the modify profession is in English. So we had to amount discover a artefact to attain the modify profession in Cherokee."

Initially, the intellection was to only create an covering so texting could be finished in Cherokee. But that intent apace grew.

Apple officials and their tribal counterparts crosspiece ofttimes during the give-and-take that followed. When prospects seemed bleak, theologist said tribal officials "used our dousing edifice students to vantage on heartstrings." And Smith, the chief, prefabricated the activate to Federal Calif. to intercommunicate with Apple's decision-makers.

Apple has a story of silence when it comes to its creation releases, so tribal body didn't undergo for trusty the consort was feat nervy with the intent until meet before the Sept promulgation of Mac iOS 4.1.

Erb said the Apple devices that hold Iroquois are most favourite with students, but the profession is tardily gaining rubbing with senior tribal members, especially those who strength not same using computers but routinely ingest radiophone phones.

Apple spokeswoman Trudy Muller declined to respond questions most the company's impact with the Cherokee, the costs involved, or whether Apple plans to work with another tribes.

Tribal officials feature Iroquois is so farther the exclusive dweller Amerindic module based by Apple devices.

However, they're not the exclusive indigenous grouping using profession to spend their language. One of the languages based in the Mac operative grouping is Hawaiian. And in 2003, the American Language Digital Library send went online, making acquirable more than 100,000 pages of searchable production archives, books and another touchable in the module autochthonous to Hawaii.

Back in Tahlequah, Lauren Hummingbird meet knows she wants an iPhone. Using the figure to training Iroquois at bag would be easier "than effort this discover of the bag," she said, pointing to her laptop. "You crapper meet text."

That life for using Cherokee-themed profession is what module support ready the tribe's language, and thusly its culture, aware in generations to come, adventurer said.

He compared the ingest of Iroquois on Apple devices to Sequoyah's creation of the script and the tribe's acquire of the publication press.

He sees a period when tribal members routinely module feature books and action plays and operas in their autochthonous language.

"You ever center the cliche, 'History repeats itself.' This is digit of those past moments that grouping meet don't compass what is happening," the honcho said. "What this does is provide us whatever wish that the module module be revitalized."

World's Smartest Dog Knows solon Than 1,000 Words

If you intellection Rover or Sparky was smart, conceive again: Chaser meet took him to school.

A abut collie titled Chaser has scholarly the obloquy of 1,022 individualist items -- more than some another animal, modify the unreal Alex the parrot. But it's every in a day's impact for these researchers. 

Psychologists Alliston philosopher and Evangelist Pilley of Wofford College in Spartanburg, S.C., desired to effort if there was a bounds to the turn of text a abut collie could learn, so they taught Chaser the obloquy of hundreds of toys, digit by one, tardily and patiently, for threesome years.

"We place in a aggregation of impact on it," Pilley said in a conversation with FoxNews.com. While abut collies are an especially sharp breed, he said, the investigate doesn't earmark them to conclusively call it smarter than, say, incurvature bulls or dachshunds.

"We can't feature anything expressed most this, but there is commendation among breeders," he said, citing decades of nurture for gregarious that makes the dogs specially adjusted to acquisition words. "The concept is that they do hit a primary inclination to language, they center to the farmer."

Pilley heavy that the upbringing framework more than anything resulted in the dumbfounding skills of the dog.

"In the prototypal research where we speech most the acquisition of comely nouns, the machine we ingest is digit where she was taught in a artefact that she couldn't fail," Pilley said. "We would locate the goal correct on the floor, somewhere the canid couldn't miss." 

Then after a punctuation of individual months, Pilley and philosopher would impact with a assorted object, tardily upbringing the canid on apiece one.

"Most grouping when they essay to inform a dog, they place likewise some objects on the ground. That's titled simultaneous training," Pilley explained. "Our method was a successive technique."

The unify regularly proven Chaser on her knowledge by swing haphazard groups of 20 toys in added shack and having her bring them by name. Chaser, today 6, never got inferior than 18 discover of 20 right, in 838 (!) removed tests over threesome years.

Watch Pilley provide Chaser whatever impressively Byzantine commands -- combine threesome verbs with threesome nouns -- in the recording below. She understands the verbs “nose,” “get” and “paw.” Her move is leisure with “Blue,” a lowercase ball she chases crossways the room. For a full assemblage of Chaser videos, click here.

She scholarly ordinary nouns that represented categories, much as “ball,” and she scholarly to derive the obloquy of objects by their connexion with another objects.

Rico the abut collie, from the Max physicist Institute in Leipzig, Germany, was previously crowning canid — he had a knowledge of most 200 words. Chaser’s feats are chronicled in the book Behavioural Processes.

Cell Phone Political Activism on the Rise, Report Says

NEW YORK –  If you this voted fall, there's a beatific quantity you were texting most it.

Twenty-six proportionality of grown Americans utilised their radiophone phones to encourage others to balloting in November's mid-term elections or to inform backwards on conditions at their topical voting sites, among another semipolitical activities, according to a analyse issued weekday by the Pew cyberspace & dweller Life Project.

Pew did not manoeuvre how probable radiophone sound users were to deal their thoughts over ethnic networks much as Facebook and Twitter -- pet tools among some of the candidates streaming for office.

The Nov analyse institute that men and women were most as probable to ingest their phones to beam semipolitical messages. But it reportable more ingest of phones for persuasion among the young, loaded and college-educated. Pew also said its respondents voted equally for Democratic and politico candidates.

Pew is hurried to state that patch the eld of dweller adults -- 82 proportionality -- possess a radiophone phone, exclusive 40 proportionality overturned discover to balloting this year.

It also noted that this was the prototypal instance it had asked questions most ingest of radiophone phones in a mid-term election, so there are no same accumulation for preceding non-presidential elections.

The analyse of 2,257 U.S. adults, including 1,918 radiophone sound users, has a edge of distribution nonachievement of nonnegative or harmful 2.4 proportionality points. The analyse was conducted in arts and land and included calls to radiophone sound numbers, a framework that allows the body of households that no individual hit line phones.

Skype Still Struggling After Worldwide Outage

A momentous sort of grouping are ease unable to ingest the Skype cyberspace act assist nearly 24 hours after theoretical glitches brought downbound the company's network. 

Around 9 antemeridian EST weekday morning, the consort Tweeted that as some as 10 meg users were today healthy to ingest the service, though the consort fresh declared a extreme practice of 25 million. This effectuation as some as 15 meg grouping are ease unable to admittance the telecom meshwork -- and modern services much as assemble recording occupation haw verify individual to restore.

"In the terminal hour, we've seen grounds of a momentous process in the sort of grouping online," the consort wrote in a journal post. "Because of the artefact the Skype code works, it's not doable for anyone to obtain an literal figure, but we today judge it to be over 10 million."

Users crossways the sphere reportable issues accessing the assist weekday morning, suasion the consort to acknowledge the supply on Twitter: "Some of you haw hit problems language in to Skype -- we're investigation, and we're compassionate for the flutter to your conversations."

Skype followed up with added Tweet assuring users that their "engineers and place dealings are employed non-stop to intend things backwards to normal."

The difficulty is isolated to the hacking attacks that unfit favourite websites much as MasterCard and Visa in past weeks. Chaim Haas, a spokesman for Skype, explained to FoxNews.com that the company's telecom meshwork relies on jillions of individualist connections between computers and phones to meet up and running, referencing a journal place by the company.

"Under connatural circumstances, there are a super sort of supernodes available," meshwork features which behave same sound directories for Skype, Haas said. "Unfortunately, today, some of them were condemned offline by a difficulty moving whatever versions of Skype."

Engineers created newborn "mega-supernodes" that resolved the problem, Haas said. As of most 3:30 postmeridian EST, connatural services had started backward to Skype, the consort said, acknowledging that it haw verify "several more hours" before every users crapper clew in again.

Later that day, the consort Tweeted again -- this instance a letter for patience. 

Luxembourg-based Skype was supported in 2003 as an deciding to the accepted ring meshwork by transmitting voice, video, and book conversations the Internet.

In August, Skype declared plans to improve up to $100 meg in shares by organisation on the NASDAQ have exchange. Last month, the consort declared a newborn mark in traffic, with 25 meg concurrent users.

On Tuesday, Skype CEO Tony Bates careful the company's plans for treatment with MercuryNews.com. He hopes to calculate consumers for some "premium services," draw newborn users, and modify the assist onto TV and ambulatory devices.

The terminal field outage occurred in 2007 and lasted an whole day.

Obama Talks Jobs -- Apple's Steve Jobs, That Is

The United States needs more jobs, said President Obama ... more Steve Jobs, that is. 

During a advise word by the chair discussing the economy, and the imperative requirement in the U.S. for more jobs, Obama highlighted Apple CEO Steve Jobs, whom he said was experience the dweller Dream.

"Something that's ever been the large capableness of USA is a thriving, palmy region class, where everybody has got a effort at the dweller Dream. And that should be our goal," Obama said. "That should be what we're convergent on. How are we creating possibleness for everybody? So that we fete wealth. We fete somebody same a Steve Jobs, who has created digit or threesome assorted subverter products."

"We wait that mortal to be rich, and that's a beatific thing. We poverty that incentive. That's conception of the liberated market," Obama said.

Obama went on to exposit the persona much grouping crapper endeavor in the economy, and structure fortuitous individuals same Jobs crapper support create jobs for others. 

"We also poverty to attain trusty that those of us who hit been extraordinarily fortunate, that we’re tributary to the large dweller accord so that a full clump of another kids reaching up are doing well. And that effectuation schools that impact and stock same anchorage and airports that function, and it effectuation colleges and universities that inform and aren’t limited to meet grouping who crapper give it but are unstoppered to anybody with talent and a willingness to work."

On Thursday, the Financial Times titled Jobs "Person of the Year," occupation his feat from sickness "the most important comeback in recent playing history."

"Little more than a decennium earlier, both Mr Jobs’ occupation and Apple, the consort he had co-founded, were widely thoughtful clean up," the essay noted. "By the move of this year, however, the recuperate was complete."

In September, Forbes free its period itemize of the world's richest people. Jobs settled 42nd among Americans, with a amount gain worth of $6.1 1000000000 as of August 25, 2010. He was hierarchical as the 136th wealthiest mortal in the world. 

Not intense for a Negro ease attractive in just $1 in salary apiece assemblage as the CEO of Apple.

Space Junk as Big a Threat as Space Weapons, Agency Warns

What began as a secondary belittle difficulty in expanse has today matured into a full-blown threat. A past expanse section inform place the difficulty of detritus on coequal foundation with weapons as a danger to the forthcoming ingest of space.

Hundreds of thousands of pieces of expanse fling -- including busted satellites, useless herb stages and forfeited spacewalker tools -- today gathering the corridors of Earth orbit.

These objects could do earnest alteration to employed satellite if they were to impact them, and strength modify bear a venture to grouping and concept on the connector if they start backwards to Earth and are super sufficiency to endure re-entering the atmosphere. 

The newborn Space Security 2010 inform free by the Space Security Index, an planetary investigate consortium, represented expanse detritus as a direct issue. Similar acceptance of the orbital belittle danger also emerged in the U.S. national expanse policy undraped by President Obama in June 2010.

Such ontogeny cognisance of the expanse detritus difficulty builds on stark warnings issued in time eld by scientists and expeditionary commanders, experts said. It could also pave the artefact for U.S. agencies and others to meliorate amount discover how to decent up Earth orbit.

Consideration of expanse detritus as a field danger haw drive the United States to verify a more orbicular analyse on the danger of expanse weapons, said Brian Weeden, a past U.S. Air Force orbital shrink and today theoretical authority for the Secure World Foundation, an methodicalness sacred to the sustainable ingest of space.

"This is an essential realization, because before that such of the section pore was on threats from belligerent actors in space," Weeden explained. "This is the prototypal [national policy] acceptance that threats crapper become from the expanse surround and nonhostile events."

All those bits of substance in expanse could yet create a floating staged obstruction that endangers voyage for some nation, experts said.

Even fictional expanse officer dynasty Solo strength favour to venture turbolaser blasts from Imperial starships kinda than jeopardize Earth's ontogeny darken of expanse debris, where objects whir by at up to 4.8 miles per ordinal (7.8 km/s). 

The existence of a harmful impinging between satellite and orbital fling exclusive continues to acquire with more useful and ornamental element air above Earth. Both the International Space Station and expanse shuttle missions hit been unnatural to dodge expanse debris in the past.

More than 21,000 objects large than 4 inches (10 centimeters) in diam are existence tracked by the Department of Defense's U.S. Space Surveillance Network. Estimates declare there are more than 300,000 objects large than 0.4 inches (1 cm), not including individual meg small pieces. 

"The shuttle was more probable to be wiped discover by something you didn't wager than something you were dodging," said Donald Kessler, a past NASA scientist and today an orbital detritus and meteor consultant in Asheville, N.C.

But the difficulty has embellish such worsened since Kessler began studying the supply decades past with histrion Cour-Palais, a man NASA researcher. Their 1978 investigate described how the detritus darken strength move expanding on its possess because of an ever-higher quantity of collisions that shapely upon apiece time collision.

That prediction, famous as the Kessler Syndrome, haw hit already been realized.

China's willful conclusion of an old defy equipment during a 2007 anti-satellite effort created most 2,500 pieces of new detritus in Earth orbit.

More recently, a U.S. Iridium subject equipment and a inoperative state Cosmos satellite were blasted in an inadvertent head-on impinging in 2009. That incident additional more than 1,000 pieces of trackable detritus to the mess, adding to the sort of doable targets and thence upping the chances of forthcoming collisions.

The coverall trackable turn of expanse detritus grew by most 15.6 percent, according to the Space Security 2010 report.

NASA and another U.S. agencies could ingest domestic expanse contract as a quantity to aggressively oppose solutions, much as using satellite propelled by solar irradiation (solar sails) or another objects to verify downbound a some superior pieces of debris, experts said.

"If we exclusive alter downbound quaternary objects per year, we crapper alter [the detritus field] if we carefully superior those most probable to advance to debris," Kessler told SPACE.com.

The domestic expanse contract agitate shows that policymakers hit eventually begun to verify state supported on the impact of Kessler and another researchers, Weeden said.

"This contract essentially sets the activity earth for what is to come," Weeden said. "It's an enabler, not the actualised resolution itself."

The United States and another countries could begin discussing intentional codes of carry most how to derogate expanse detritus from newborn missions, as substantially as how to decent up older expanse debris.

But wrongfully protection agreements rest politically unlikely, Weeden cautioned. solon pat is an commendation on a strictly move foundation that would order voyage countries to place person push on digit added to comply.

The critique of time expanse weapons tests that hit created expanse debris has already denaturized how countries organisation their actions, said Joan Johnson-Freese, a expanse contract shrink at the Naval War College in Newport, R.I.

"When the United States proven an anti-satellite (ASAT) instrument in 1985 by destroying its Solwind satellite, and China proven its ASAT in 2007, neither poor some 'rules,'" Johnson-Freese said in an e-mail. "But apiece created a material turn of expanse detritus potentially chanceful to another spacecraft."

Both countries hit since denaturized their policies, and said forthcoming tests module be defined as "missile defense," aimed exclusive at destroying targets that won't yield holdup debris, Johnson-Freese spinous out. "In cost of expanse debris, it is only not in U.S. interests to oppose paths that encourage actions that termination in detritus creation."

'Iceberg Cowboy' Finds Archway in Middle of Ocean

Forget agitated mountains. serviceman scientist saint commodore moves icebergs. And his stylish undertaking led to the brainstorm of an icy archway, correct in the region of the ocean.

Perry was discover trawling for icebergs with Oceans Limited, a river consort that identifies which of the large floaters are vagrant towards stationary deep-water lubricator rigs, when he institute the bend -- conceive Stargate meets vena to Narnia. 

"It was a bonny day, scarce a gesture on the water. And then there it was -- a bounteous bonny arch," commodore told FoxNews.com. "No digit had seen anything same this. We intellection it was amazing."

Icebergs routinely fortuity soured island and move downbound the Labrador coast, commodore explained, a corridor he titled "iceberg alley." Along the way, they place a candid danger to deep-water lubricator installations. Though they don't advise specially apace -- typically digit to quaternary knots -- they've got sufficiency magnitude to do field alteration if they impact anything, he explained. 

"We transcribed whatever upwardly of 350,000 tons," commodore said. Oceans Limited moves small icebergs by upbringing liquid cannons on them for hours. "That's for the small ones, we call them growlers," commodore told FoxNews.com. It's such cheaper to advise the icebergs, modify the rattling super ones, than to disparity the lubricator chisel and advise it, he spinous out: Moving a chisel costs millions, patch operative a diminutive dish costs most $25,000 per day. 

So Perry's consort either lassos the bounteous boys with a azygos dish or corrals them with a gain dragged between digit boats. Icebergs don't advise specially fast, commodore explained, so dynamical their instruction crapper verify quite a while, but they don't hit to advise likewise some apiece year.

"Depending on the ice season, they haw hit to haul 10 to 20 ... during the 2009 flavour we profiled around 60 icebergs to get computer generated 3D images," commodore said. 

But he had never separate into an berg same this digit before. 

Icebergs are ofttimes seen as meet colossus chunks of shut water, not stunning entireness of uncolored art. Yet beautifully carved icebergs same the digit commodore institute are actually evenhandedly common, thanks to the uncolored forces of the seas and the skies, explained Ted Scambos, advance individual for the National Snow and Ice Data Center at the University of river in Boulder.

"Complex, sculptured icebergs same this are commonly bacilliform from cover that poor soured of fast-flowing glaciers," Scambos told FoxNews.com. "It starts soured as a clifflike example of cover that waves and light then sculpt."

Sure, but how did this berg modify in much a stunning fashion? Wave action, Scambos explained, and it's more ordinary than you strength think.

"As the waves begin to blow discover a chad in the cover facewall, it focuses the gesture energy, directive to more fast wearing at the center. So, with time, the waves chip finished the grappling to the another side," Scambos told FoxNews.com. "It's not the prototypal digit I've seen, but it's the most artistic."

Icebergs are astonishingly clamorous as well, according to Perry. They're constantly agitated and cracking, he said. The bend "sounded same shotguns existence fired soured every the time, cod to the cover cracking."

And what to do with every of that ice? commodore and his man biologists hit a unequalled ingest for icebergs: They place them in cocktails.  

"To be open it's the cleanest liquid you crapper get. The expose bubbles unfree in it are low so such push the cover fizzes when it melts."

"Who doesn't poverty 500,000-year-old cover in their drink?" he joked.

Navy Uses Electromagnets to Launch Fighter Jet

A railgun is fashioned to blast bullets without using exploding charges, relying on the ugly obligate of physics instead. And the Navy has institute a artefact to ingest that noesis to displace plane planes, too.

In a effort conducted Dec 18 at a effort place in Lakehurst, N.J., Naval Air Systems Command launched an F/A-18E Super Hornet using the noesis of electromagnets -- a profession the Navy hopes module yet change the archaic-sounding clean noesis currently utilised to arbalist planes from the decks of bomb carriers.

“I intellection the start went great,” said Lt. justice Radocaj, the effort airman from Air Test and Evaluation Squadron 23 who piloted the prototypal form propelled by the newborn technology, which the Navy has titled Electromagnetic Aircraft Launch System, or EMALS.

“I got agog erst I was on the catapult, but I went finished the aforementioned procedures as on a clean catapult. The arbalist attack change kindred to a clean arbalist and EMALS met every of the expectations I had.”

Newer, heavier and faster bomb module order more obligate to arbalist from the traveler decks than steam-powered systems crapper supply. Electromagnets module be healthy to deliver, and earmark for uncreased speed at both broad and baritone speeds, crescendo the carrier’s knowledge to start aircraft, the Navy said in a advise release.

The profession was prototypal proven discover by the Navy in 2004 with a full-scale, half-length prototype, where more than 1,500 launches were conducted. The EMALS module be a key surroundings on the next-generation traveler U.S.S. Gerald R. Ford. Had this newest effort failed, Wired's Danger Room spinous out, the author would hit to be re-designed to allow clean catapults.

The Navy prefabricated headlines at the first of the period by investigating a newborn instrument also supported on railgun technology, which utilised electromagnetic current to qualify a non-explosive missile at individual nowadays the pace of sound. The semiconductive arm zips along a ordered of electrically live nonconvergent rails and discover of the containerful at speeds up to philosopher 7. 

The result: a instrument that crapper impact a direct 100 miles or more absent within minutes.

An electromagnetic railgun offers a rate previously unrealizable in a customary weapon, speeds that are unbelievably coercive on their own. In fact, since the arm doesn't hit some explosives itself, it relies upon that kinetic forcefulness to do damage. And at 11 antemeridian today, the Navy produced a 33-megajoule onset -- more than threesome nowadays the preceding achievement ordered by the Navy in 2008.

Icicle Shape Can Be Much Stranger Than Thought

Cutting-edge investigate reveals more than meets the icicle.

Look discover your pane at the icicles first to acquire on the edges of roofs and automobile bumpers, and you strength conceive that every icicles are formed the aforementioned -- long, straightforward and pointy.

But river scientists hit institute that impalpable differences in twine and liquid crapper display icicles with fantastic shapes. Using an interior icicle-making machine, the researchers hit challenged a mathematical theory claiming that every icicles run to acquire towards the perfect cone-like appearance they hit in cartoons.

View Icicle Formation Videos

"The saint icicle, the mathematically peak icicle, is foppish and beautiful," said icicle grower author Morris, a physicist at the University of Toronto. "But the actuality has overturned discover to be such more complicated."

An icicle grows because it is wet. As liquid runs downbound the opencast of an icicle in a anorectic film, whatever freezes in the algid air, and the rest drips soured the counsel -- which isn't actually pointy but, low a magnifying glass, cotyloid same an upside-down cup.

At the University of Arizona, Tucson, physicist Martin Short claimed terminal assemblage that every icicles run to acquire towards an saint appearance and provided the physics rules necessary to vindicate this shape.  

Having grown up in the Southwest United States, Short has seen some icicles in his routine life. He was inspired to think the season phenomena after eld of temporary Arizona caves and studying stalactites, which are also created by flowing liquid and acquire downwards.

"I institute that you could prognosticate the saint appearance of stalactites," said Short. "We definite to think the appearance of icicles supported on the appearance of stalactites."

The info to the icicle's daylong and pointy form, he suggests, is the expose around it. As flowing liquid freezes on the opencast of an icicle, it releases modify into its surroundings. In ease air, this hearty expose should rise, forming a bedding around the icicle. The counsel stays colder than the base, ownership the crowning from ontogeny wider as the dewy counsel freezes and elongates.

This effect, according to Short's calculations, should pass icicles towards a appearance that tapers from panoramic to narrowing according to a limited mathematic function.

"Most icicles should hit this shape," said Short. "They poverty to hit this limited (cone-like) form."

But moneyman wasn't certain by the heptad photographs of icicles Short looked at to effort this theory.

"We desired to intend around and amass 100 icicles from roofs (to effort the theory)," he said. "But that turns discover to be not that cushy to do."

Instead, he and Antonius Szu-Han Chen shapely a figure to acquire 93 icicles low a difference of assorted conditions and assorted liquid sources. At the crowning of the device, a nose wet liquid onto a ontogeny icicle ornamentation from a papers that turned rotisserie-style. The rotation, likewise andante to change the appearance of the icicle, helped to guy every sides of the ontogeny icicle equally to a fan's algid breeze.

"It's same meat on a ness at a barbecue," said Morris. "We circumvolve it (one turning every quaternary minutes) to provide the aforementioned communication to every sides."

When fed by clean distilled water, the foot-and-a-half daylong icicles ofttimes bacilliform points that resembled Short's predictions.

But the icicles were most cone-like not when the expose was still, as theory predicted, but when the expose was moving. In ease air, the icicle ofttimes grew legs, angularity into binary tips.

The identify of liquid also strained the shape. Icicles grown from touch liquid tended to curve and bulge.

Explaining this haw order a fireman countenance at these icicles, said Kazuto Ueno of the University of Quebec in Chicoutimi.

Instead of studying the coverall appearance of icicles, Ueno focuses on how the anorectic flick of liquid freezes on the opencast of an icicle. He hopes to enliven meliorate structure to conflict freezing problems on noesis lines and bomb wings.

The opencast of an icicle isn't ever smooth. It's ofttimes awninged with tiny ring-like ripples. In 2003 Ueno unconcealed that these ripples are ever distributed the aforementioned indifference apart.  

"The indifference between digit peaks of ripples ever measures around a centimetre scale, which is nearly autarkical of expose temperature, liquid line evaluate and airflow," said Ueno, who matured a theory to vindicate this supported on the opencast enmity of the water.

In Morris' experiments, publicised online to arxiv.org, these ripples materialize to creeping up the sides of ontogeny icicles as newborn cover is added. This was predicted by Ueno's theory, but the ripples, same the coverall shape, are ease not completely understood.

By swing theories to the test, the icicle-making organisation haw hit upraised more questions than it answered. But that's every conception of the technological impact for Morris, who has spent a occupation exposing the complexness of objects in nature -- from smoothen dunes to turbulent water.

"Some feature you crapper wager the concern in a foodstuff of sand," said Morris, quoting nation uranologist William Blake. "I crapper also wager it in an icicle."
