The Blue Planet's New Water Budget: Do We Have Enough? -- Science Daily

ScienceDaily (Mar. 5, 2012) — Investigating the history of water on Earth is critical to understanding the planet's climate. One central question is whether Earth has always had the same amount of water on and surrounding it, the same so-called "water budget." Has Earth gained or lost water from comets and meteorites? Has water been lost into space? New research into Earth's primordial oceans conducted by researchers at the Natural History Museum of Denmark at the University of Copenhagen and Stanford University revisits Earth's historical water budget.

The Hardest Movies To Turn Off Once You Start Watching Them



The Ten Hardest Movies To Turn Off Once You Start Watching Them -- PJ Media

I hereby provide my list of the Ten Hardest Movies to Turn Off Once You Start Watching Them. These may not be the best movies ever made — or they may be. But no matter where you come in on these films — no matter whether you intended to watch them or stumbled on them while lazily channel surfing — they grab you and won’t let you go. Or at least they grab me — which is more important, because I live here and you don’t.

Except for the first one — the most compulsively watchable film ever made — they’re not in any particular order. And any further suggestions will be welcomed and watched.

My Comment: I totally agree with this list. And yes .... I love the movie HEAT.

Why Pot Smokers Forget


How Marijuana Makes You Forget -- Nature

Drug affects previously overlooked brain cells that have a crucial role in memory formation.

Researchers have discovered how marijuana disrupts short-term memory.

The drug impairs users’ working memory — the ability to retain and use information over short periods of time. Neuroscientists Giovanni Marsicano of the University of Bordeaux, France, and Xia Zhang of the University of Ottawa Institute of Mental Health Research now show that this common side effect occurs because of a previously unknown signalling mechanism between neurons and non-neuronal cells called astrocytes. Their work is published today in Cell1.

Find The U.S. Military's Hidden QR Codes



Find The Military's Hidden QR Codes And Rake In $40,000 -- MSNBC/Innovation

You'll likely need your social media networks for scavenger hunt contest already under way.

Got a smartphone? You can win up to $40,000 if you're first to find all of the U.S. military's special QR codes hidden across the continental United States. But the huge geographical scope of the contest means that people will probably need to turn to their social media networks to find all the codes.

There's a reason why the Defense Advanced Research Projects Agency (DARPA) wants to watch code hunters collaborate on Facebook and Twitter. It planned out the " DARPA CLIQR Quest " as a real-life game to simulate how the public can help find essential resources during national emergencies — a very real concern for the military when responding to humanitarian crises or disasters such as the Haiti earthquake of 2010.

Oceans Acidifying At A Faster Rate Than At Any Time In The Last 300 Million Years

Will they survive? (Image: Reinhard Dirscherl/Waterframe/Getty Images)

Oceans Acidifying At Unprecedented Speed -- New Scientist

Humanity's greenhouse gas emissions may be acidifying the oceans at a faster rate than at any time in the last 300 million years. The sheer speed of change means we do not know how severe the consequences will be.

As well as warming the planet, carbon dioxide seeps into the oceans and forms carbonic acid. As a result the water becomes more acidic.

The pH is currently dropping by about 0.1 per century. This ocean acidification harms organisms such as corals that rely on dissolved carbonate to make their shells. It also disrupts behaviour in some animals.

Meet Your New Robot Receptionist



Meet Your New Robot Receptionist, the DARPA ARM 'Bot -- Popular Science

Never worry about answering the phone or stapling documents again.

Bad news for long-term receptionists: DARPA's ARM (Autonomous Robotic Manipulation) robot can perform a whopping 18 different reception-ready tasks, from stapling to answering the phone to...turning on a lamp? Grasping things? Also it can't speak, or redirect calls, really, but it can drill a hole in a piece of wood, which I'm not entirely sure I can do, so it's an easy shoo-in for our incredibly prestigious Robot of the Week award. Congratulations! Watch the video after the jump.

Internet Users Can Watch Who Is Spying On Them In Blow Against Google's New Snooping Policy

Google's HQ: Google ignored an international outcry to launch its new privacy policy this week - despite concerns the policy may actually be illegal in many territories

Turning The Tables On Big Brother: Now Internet Users Can Watch Who Is Spying On Them In Blow Against Google's New Snooping Policy -- Daily Mail

* Free Collusion add-on shows which companies watch as you browse
* 'Real time' illustration of marketing companies snooping

Mozilla, the maker of Firefox, has unveiled a new add-on for the popular web browser that gives web users an instant view of which companies are 'watching' them as they browse.

The move comes the same week that Google pushed ahead with its controversial new privacy policy, built to provide even more data for Google's $28 billion advertising business - despite concerns that the massive harvesting of private data might be illegal in many countries.

The Collusion add-on will allow users to 'pull back the curtain' on web advertising firms and other third parties that track people's online movements, says Mozilla CEO Gary Kovacs.

A New Twist In The Antimatter Mystery

CDF was one of two multi-purpose experiments at the US Tevatron accelerator near Chicago

New Twist In Antimatter Mystery -- BBC

Physicists have taken a step forward in their efforts to understand why the Universe is dominated by matter, and not its shadowy opposite antimatter.

A US experiment has confirmed previous findings that hinted at phenomena outside our understanding of physics.

The results show that certain matter particles decay differently from their antimatter counterparts.

Such differences could potentially help explain why there is so much more matter in the cosmos than antimatter.

Giant Penguins 'May Have Roamed New Zealand' -- The Telegraph

Fossilised remains of one of the largest penguins ever, an "elegant" giant standing 1.3 metres (52 inches) tall, have been found in New Zealand, scientists said.

The penguin lived 27-24 million years ago, when New Zealand was mostly underwater and consisted of isolated, rocky outcrops that offered protection from predators and plentiful food supplies, researchers said.

The first traces of the penguin, dubbed Kairuku - Maori for diver who returns with food - was found embedded in a cliff at Waimate in the South Island by University of Otago paleontologist professor Ewen Fordyce in 1977.

Were Europeans The First Americans?

Source: Dennis Stanford and Bruce Bradley. The Washington Post.
An established theory says the first Americans walked across the Bering Sea about 13,000-15,000 years ago. But stone tools found in the mid-Atlantic suggest an arrival from Europe about 20,000-22,000 years ago. The tools match those made by the mysterious Solutrean people of ice-age Iberia.

Radical Theory Of First Americans Places Stone Age Europeans In Delmarva 20,000 Years Ago -- Washington Post

When the crew of the Virginia scallop trawler Cinmar hauled a mastodon tusk onto the deck in 1970, another oddity dropped out of the net: a dark, tapered stone blade, nearly eight inches long and still sharp.

Forty years later, this rediscovered prehistoric slasher has reopened debate on a radical theory about who the first Americans were and when they got here.

Archaeologists have long held that North America remained unpopulated until about 15,000 years ago, when Siberian people walked or boated into Alaska and then moved down the West Coast.

Chinese Drones Will Use Genetic Algorithms to Learn to Hunt For Submarines -- Popular Science

China usually holds its military hand very close to the vest--that, or things “mysteriously” leak that it doesn’t (does) want the world to know about--so we’re left to wonder why the People’s Republic has decided to publish this in the journal Advanced Materials Research. Nonetheless, it’s pretty interesting. Chinese navy researchers have plans for a new submarine hunting scheme that uses ship-launched UAVs running genetic algorithms.

Remote Aliens Could Detect Life On Earth By Looking At The Moon -- Popular Science

New detection method could help spot signs of life on exoplanets.

So many exoplanets may hold water, atmospheres, just-right temperatures and a rocky surface for life to flourish — we just need to know where to look. Once astronomers have pinpointed a good candidate, we also need to know how to look — which instruments and methods might sniff out the right chemical signatures of life. A new trick that essentially amplifies those signatures could be one way to do it. Astronomers at the European Southern Observatory just discovered life on Earth with this method, treating our home as if it were an exoplanet.

The Future Of Warfare?

Direct Brain Control Of Weapons Prompts Ethical Debate -- The Inquirer

BRINGING A WHOLE NEW TWIST to the phrase 'blue screen of death', scientists are calling for a public debate on the ethics of using direct brain control technology to manage systems including weaponry.

The Nuffield Council on Bioethics has launched a public consultation on the ethics of using technologies such as brain computer interfaces (BCIs) in non-medical situations. The organisation defines a BCI as a system for measuring and analysing brain signals and translating them into outputs such as computer-based communication or control of a device.

One-In-Eight Chance Of Solar Megaflare Causing Trillions Of Dollars Of Damage In Next Ten Years, Scientists Warn -- Daily Mail

Earth has a 12 per cent chance of being struck by a solar megaflare of such violent proportions over the next decade it could cause trillions of dollars of damage, scientists warned today.

The event would rival the last giant sunstorm, known as the Carrington Event, more than 150 years ago when telegraph stations caught fire and their networks suffered massive black-outs.

In today's electronic-infused world, the consequences of such a huge magnetic force raining down on the planet could be catastrophic and may take a decade to recover from.

How To Fill A Gas Tank For $1 A Gallon



How A Billionaire Fills Gas Tank For $1 A Gallon -- CNN

Long Beach, California (CNN) -- Gasoline at $4 a gallon is no worry for T. Boone Pickens, the billionaire energy investor from Texas. He drives from his home to his office in a car that runs on fuel costing less than $1 a gallon.

His method: He has a device that fuels his Honda Civic GX with natural gas from the pipes that serve his home. And he thinks there's a lesson there for America's energy woes.

Pickens, who is speaking Wednesday at the TED2012 Conference in Long Beach, California, said America needs to make natural gas a building block of a plan for ending oil imports from the Organization of Petroleum Exporting Countries.

Natural gas is "cheaper, it's cleaner, it's abundant and it's ours, and we're fools not to use it," Pickens said in an interview with CNN.

It is counting the number of units of application software downloaded from the company's App Store – and the rise of a business that barely existed five years ago, but which now dominates daily conversation so much that the phrase, "There's an app for that", has become both an offer of help and a joke.

The counter is expected to hit the target by early March. By then, users will have spent about £3.6bn buying apps through the store, of which Apple will have passed on £2.5bn and retained £1.1bn.

Apple Buys Chomp

Apple Said To Pay About $50 Million For Application-Search Startup Chomp -- Bloomberg

Apple Inc. (AAPL), the world’s most valuable company, acquired San Francisco-based Chomp Inc., which helps users sort through the widening array of software applications for mobile devices.

The Cupertino, California-based company paid about $50 million for Chomp, according to a person familiar with the matter, who asked not to be named because the specifics are private. Apple confirmed the deal yesterday, without disclosing the purchase price.

“We buy smaller technology companies from time to time and generally don’t comment on our purposes or plans,” said Amy Bessette, a spokeswoman for Apple.

Is This The Future of Touchscreen Tech?



Is This The Future of Touchscreen Tech? New Video Will Blow Your Mind -- Mashable Tech

Gorilla Glass manufacturer Corning has unveiled a follow-up YouTube video to its wildly successful “A Day Made of Glass,” providing another look into what the future could be like with the growth of glass touchscreen interfaces, from innovative chalkboards and activity tables in classrooms to uses for it in hospitals.

Corning released two versions of “A Day Made of Glass 2″ — one with a narrator and another, abbreviated version without commentary — the video follows the life of young Amy and her family as they go through their day using various products made of glass. Amy does classwork on a glass tablet, controls the temperature of the car from the backseat and even attends a field trip at the Redwood Forrest with an interactive signage that brings learning to life. Her teacher also works with students on interactive touchscreen activity tables. Corning expects these activity tables to be rolled out in the near future.

Were Neutrinos Faster-Than-Light .... Or Not?



'Faster-Than-Light' Particles May Have Been Even Speedier -- CBC

Subatomic particles clocked at speeds exceeding the speed of light may have been going even faster than they appeared, physicists say.

A problem with some of the equipment used in the original experiment may have led to an overestimate of the time it took the particles, known as neutrinos, to make their 730-kilometre journey, reported CERN, the European Organization for Nuclear Research in a statement Thursday.

As a result, their speed may have been underestimated.

De-Classified UK Submarine Data Will Be Used To Assist Climate Science

Environmental data is routinely collected by submarines and other Navy vessels

UK Submarine Data De-Classified To Aid Climate Science -- BBC

The UK Ministry of Defence is to de-classify submarine data to help shed light on climate change in the Arctic.

Environmental data are routinely monitored by Navy vessels, but the measurements are highly sensitive because they could give away positions.

A dataset from one submarine mission will be released to give a snapshot of conditions under the ice.

It is hoped that further data could be released in future, yielding clues to how the Arctic is changing.

Closer To A Heroin Vaccine

National Institute of Psychiatry's Director Maria Elena Medina speaks about the patent of a new vaccine that could reduce addiction to heroin, during a news conference at the institute in Mexico City February 23, 2012. Researchers at the institute say they have successfully tested the vaccine on mice and are preparing to test it on humans. The vaccine, which has been patented in the United States, works by making the body resistant to the effects of heroin, so users would no longer get a rush of pleasure when they smoke or inject it.

Mexican Researchers Patent Heroin Vaccine -- Yahoo News/Reuters

MEXICO CITY (Reuters) - While Mexico grapples with relentless drug-related violence, a group of Mexican scientists is working on a vaccine that could reduce addiction to one of the world's most notorious narcotics: heroin.

Researchers at the country's National Institute of Psychiatry say they have successfully tested the vaccine on mice and are preparing to test it on humans.

The vaccine, which has been patented in the United States, works by making the body resistant to the effects of heroin, so users would no longer get a rush of pleasure when they smoke or inject it.

Why Astronauts Crave Tabasco Sauce -- NPR

If you think astronauts just want dehydrated dinners and freeze-dried ice cream, think again. After a few days in space, they start reaching for the hot sauce.

In fact, they may start craving foods they didn't necessarily like on Earth.

"They crave [spicy] peppers, they crave sour and sweet things," says Jean Hunter, a food engineer at Cornell University. That means Tabasco sauce was definitely on the menu for space shuttle astronauts.

Catlin Seaview Survey

Google Street View Goes Undersea -- MSNBC

Less than a month after Google Ocean drowned our dreams of Atlantis by updating a image that previously showed mysterious grid patterns on the sea floor, the search giant is back with an underwater Street View.

Catlin Seaview Survey, the project's official name, launched Thursday with what New Scientist describes as "an unprecedented photographic tour of Australia's Great Barrier Reef." It is even more ambitious than Google's land version, which provides an eye level view of neighborhoods, parks and other public areas all over the world. This submerged 360 degree photo survey's "aim is to learn as much as possible about the reef's state of health from a panoramic underwater photographic and video survey – and let the rest of us enjoy the reef's untrammelled beauty online."

The 'Wow!' Signal


The 'Wow!' Signal: One Man's Search for SETI's Most Tantalizing Trace of Alien Life -- The Atlantic

For decades, Robert Gray has been trying to duplicate the most surprising and still-unexplained observation in the history of the search for extraterrestrial life.

Late one night in the summer of 1977, a large radio telescope outside Delaware, Ohio intercepted a radio signal that seemed for a brief time like it might change the course of human history. The telescope was searching the sky on behalf of SETI, the Search for Extraterrestrial Intelligence, and the signal, though it lasted only seventy-two seconds, fit the profile of a message beamed from another world. Despite its potential import, several days went by before Jerry Ehman, a project scientist for SETI, noticed the data. He was flipping through the computer printouts generated by the telescope when he noticed a string of letters within a long sequence of low numbers---ones, twos, threes and fours. The low numbers represent background noise, the low hum of an ordinary signal. As the telescope swept across the sky, it momentarily landed on something quite extraordinary, causing the signal to surge and the computer to shift from numbers to letters and then keep climbing all the way up to "U," which represented a signal thirty times higher than the background noise level. Seeing the consecutive letters, the mark of something strange or even alien, Ehman circled them in red ink and wrote "Wow!" thus christening the most famous and tantalizing signal of SETI's short history: The "Wow!" signal.

Robot Fish


Real Fish Welcome Robotic Overlord Into Their School -- Wired Science

A robotic fish has sailed across an aquatic uncanny valley by tricking real fish into following it upstream.

The feat could lead to better understanding of fish behavior and perhaps some means to divert them from environmental disaster scenes.

“Although some previous works have successfully investigated the interactions between live animals and robots or animal-like replicas, none of these studies have considered robots that are designed to simulate animal locomotion,” wrote the authors of a new study about the robot.

Man's First Homes And Settlements

Shelters Date To Stone Age -- Science News

Hunter-gatherers hung out in huts long before farmers built villages.

The remains of a couple of nearly 20,000-year-old huts, excavated in a Jordanian desert basin, add to evidence that hunter-gatherers built long-term dwellings 10,000 years before farming villages debuted in the Middle East.

These new discoveries come from a time of social transition, when mobile hunter-gatherers hunkered down for months at a time in spots that featured rivers, lakes and plentiful game, say archaeologist Lisa Maher of the University of California, Berkeley and her colleagues. Discoveries in and around hut remnants at a Stone Age site called Kharaneh IV include hearths, animal bones and caches of pierced seashells and other apparently ritual items, Maher’s team reports in a paper published online February 15 in PLoS ONE.

Astronomers Discover New Type Of Planet – The Water World -- The Telegraph

A watery planet with a thick, steamy atmosphere has left astronomers fumbling for their classification books.

The water world, which has been named GJ1214b, is 2.7 times bigger than earth but weighs almost seven times as much.

GJ1214b orbits a red-dwarf star at a distance of two million kilometres, suggesting temperatures may reach up to 200C.

Astronomers believe the planet is an entirely new classification of celestial body, with the mixture of water and high temperatures meaning there is a chance new alien materials could have been produced.

Previous types of planetary body known to exist include a rocky surface similar to earth, gas giants like Jupiter, and ice giants like Uranus.

Neutrinos Are Not Moving Faster Than Light

Bummer: Faster-Than-Light Neutrinos Weren't, and It Was the Cable Guy's Fault -- Popular Science

Apparently neutrinos are not moving faster than light after all — some of the brightest minds in modern physics were bamboozled by a loose wire.

If you care about physics, Einstein or controversies, you’ll recall the excitement last fall about neutrinos that were supposedly moving faster than light. The ghostly particles, which can move through the Earth and through you without slowing down, were leaving a particle beam in Geneva and traveling under the Alps to Gran Sasso, Italy, in less time than it would take light to travel the same distance. The neutrinos were only 60 nanoseconds early, but still — the result, which the experimenters could not explain, suggested they were moving faster than light.
