What Happens As We Get To Absolute Zero

Why Can’t We Get Down To Absolute Zero? -- io9

What is Absolute Zero, and does it really exist anywhere in the universe? Could we ever reach Absolute Zero in real life?

There are all sorts of reasons to be curious about the limits of cold. Maybe you're an incredibly lame supervillain who uses the power of freezing, and you want to understand the extent of your powers. Or you're wondering if it would be possible to outrun a wave of cold. Either way, in this week's "Ask a Physicist" we'll explore the farthest limits of cold.

Hackers Had 'Control' Of Nasa Computers

NASA said the loss of data did not affect the operations of the International Space Station

Hackers Had 'Full Functional Control' Of Nasa Computers -- BBC

Hackers gained "full functional control" of key Nasa computers in 2011, the agency's inspector general has told US lawmakers.

Paul K Martin said hackers took over Jet Propulsion Laboratory (JPL) computers and "compromised the accounts of the most privileged JPL users".

He said the attack, involving Chinese IP addresses, was under investigation.

In a statement, Nasa said it had "made significant progress to protect the agency's IT systems".

Mr Martin's testimony on Nasa's cybersecurity was submitted to the House Committee on Science, Space and Technology's Subcommittee on Investigations and Oversight.

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.

My Comment: In short .... marijuana use has consequences. But will anyone listen .... hmmm .... I doubt it.

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 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.

My Comment: This data is significant .... and scary to think about.

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
* Unveiled as Google shifts privacy policy to enable more advertising
* Mozilla aims to share data with privacy campaigners

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.

My Comment: Kudos to Firefox.

A New Twist In The Antimatter Mystery

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.

Robot Helicopters Perform James Bond Theme

Flying robot quadrotors perform the James Bond Theme by playing various instruments --
including the keyboard, drums and maracas, a cymbal, and the debut of an adapted guitar built from a couch frame.

Robot Helicopters Perform James Bond Theme Music -- Christian Science Monitor

Researchers at the University of Pennsylvania's General Robotics, Automation, Sensing and Perception Lab wowed attendees at this year's TED conference with a video of tiny robot quadroters performing the James Bond theme music.

Sometimes we just crave the simple things in life: smelling freshly baked bread, getting a baby to laugh, watching a cat fall asleep on your lap, or having someone scratch your back.

And other times, you just want to watch a bunch of robotic quadrotors performing the James Bond theme song.

If you are reading this story, now is apparently one of those times. If you haven't done so already, watch the video at the top of this page.

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.

My Comment: 52" tall .... those were tall penguins.

The Unique Ability To Spell Backwards

Health: Teen Speaks To CBS3 About Her Ability To Instantly Say Words Backwards -- CBS

PHILADELPHIA (CBS) – It’s like an easy game for 14-year-old Alyssa Kramer. She can easily say words backwards in seconds. Her video on YouTube quickly got a million hits, and now she has her own channel: alyssatalkingback.com. CBS3 asked when she realized she had the special ability.

“Whenever I learned how to read, I just started doing it. I have a photographic memory, and whenever someone tells me a word, I can see it in my head. And if I want to spell it backwards then, it can flip and I’ll read it that way,” Alyssa says.

My Comment: I just tried to do it myself .... it ain't easy.

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.

China Will Use Drones To Hunt Submarines

The U.S. Navy's Fire Scout Ship-Launched UAV China plans to hunt submarines using its own sea-launched UAVs running genetic algorithms. U.S. Navy

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.

My Comment: The Chinese are making their intentions very clear .... they are going to focus on drone development.

One Could Detect Life On Earth By Looking At The Moon

Crescent Moon and Earthshine The thin crescent moon sets over ESO's Paranal Observatory in Chile. The crescent is clearly visible, but you can also see the rest of the moon very faintly, because of the phenomenon known as earthshine. Sunlight bouncing off the Earth illuminates the surface of the moon. This image was captured Oct. 27, 2011. Mercury and Venus are there, too, by the way. ESO/B. Tafreshi/TWAN

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 In Next Ten Years

Destructive: A solar flare many times greater than this one could be catastrophic for Earth. There is a 12 per cent chance of one occurring over the next decade

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.
