Breakthroughs In Invisibility Cloak Technology

Scientists Make 'Invisibility Cloak' Breakthrough -- The Telegraph

Scientists in the United States have made a further step towards creating an "invisibility cloak" by masking a large, free-standing object in three dimensions.

The lab work is the latest advance in a scientific frontier that uses novel materials to manipulate light, a trick that is of huge interest to the military in particular.

Reporting in the New Journal of Physics, researchers at the University of Texas in Austin cloaked a 7.2-inch cylindrical tube from light in the microwave part of the energy spectrum.

Those hoping for a Harry Potter-style touch of wizardry will be disappointed however. To the human eye, which can only perceive light in higher frequencies, there would have been no invisibility.

Contact Lenses: How They Will Bring Virtual Reality to U.S. Soldiers by 2013 -- International Business Wimes

It has been the stuff of science fiction for decades, but the U.S. military announced on Tuesday it is close to developing a virtual reality contact lens to enhance soldiers' vision on the battlefield.

The Defense Advanced Research Projects Agency, or DARPA, is working with Washington-based company Innovega to develop a system of contact lenses and small, wearable glasses giving soldiers battelfield information in realtime.

The Terminator-style vision would enable soldiers to simultaneously focus on the battlefield and mission data, such as live video from an overhead drone, at the same time.

Take The Alzheimer's Test: The 21 Questions That Can Reveal If YOU Are At Risk... -- Daily Mail

A quick test that tells if your loved one is at risk of Alzheimer’s disease has been devised by doctors.

The 21-question test distinguishes between normal absent-mindedness and the more sinister memory lapses that may signal the early stages of dementia.

The questions are designed to be answered by a spouse or close friend.

The Alzheimer’s Questionnaire, which is almost 90 per cent accurate, measures mild cognitive impairment – the slight memory lapses that can be a precursor of the disease.

More Internet Censorship On The Way

Posts on Google's Blogger service will now be taken down if they violate local laws - so in repressive regimes, governments may be able to use local speech laws to block controversial posts

Google Joins Twitter In Censorship Storm: Site May Now Block Blog Posts In Line With Requests From Oppressive Regimes -- Daily Mail

* Blog posts will be blocked at national government request
* Campaigners fear 'the end of the global internet community'
* But Google claims move will allow MORE free speech

Google's informal motto is 'don't be evil', but a huge change to its Blogger service could see the search giant help oppressive governments stamp out voices of protest.

Bloggers who have relied on the popular service to organise dissent as seen during the Arab Spring could find their posts being blocked by Google itself.

The company will now block posts or blogs from being seen in a country if they their local laws, handing a victory to regimes that crack down on free speech to keep a lid on dissent.

What Happens When Our Brain Ages

New Insight Into Aging Brains -- Wall Street Journal

Study Links 24% of Intelligence Changes Over a Person's Life to Genetic Factors.

Nearly a quarter of the changes often seen in a person's intelligence level over the course of a lifetime may be due to genes, a proportion never before estimated, new research shows.

The study suggests that genes may partly explain why some people's brains age better than others, even though environmental factors likely play a greater role over a lifetime.

Understanding the factors behind healthy mental aging has become an increasingly vital one for societies with large elderly populations. However, it isn't an easy task.

The Biggest Unsolved Mysteries In Physics

5 Of The Biggest Unsolved Mysteries In Physics -- Y!Tech/Yahoo News

The mysteries of the universe are as vast and wide as existence itself. Throughout history, mankind has searched and struggled to find the answers tucked away inside the universe and everything we see around us. As Deep Thought said in the Hitchhiker's Guide to the Galaxy, "I think the problem, to be quite honest with you, is that you've never actually known what the question is."

All Time Coldest U.S. Record Nearly Broken

Bitter Cold Records Broken In Alaska – All Time Coldest Record Nearly Broken, But Murphy’s Law Intervenes -- WUWT

Jim River, AK closed in on the all time record coldest temperature of -80°F set in 1971, which is not only the Alaska all-time record, but the record for the entire United States. Unfortunately, it seems the battery died in the weather station just at the critical moment.

While the continental USA has a mild winter and has set a number of high temperature records in the last week and pundits ponder whether they will be blaming the dreaded “global warming” for those temperatures, Alaska and Canada have been suffering through some of the coldest temperatures on record during the last week.

`Space Hurricane`From The Sun Sweeping The Planet Right Now

'Space Hurricane' From The Sun Sweeping Over Our Planet -- MSNBC

Flights rerouted due to solar storm; radiation rated strongest since 2003

A wave of charged particles from an intense solar storm is raising alerts about airline flights and satellite operations — and raising the prospect of stunning auroral displays.

The storm began when a powerful solar flare erupted on the sun Monday, blasting a stream of charged particles toward our planet. This electromagnetic burst — called a coronal mass ejection, or CME — started hitting Earth somewhere around 10 a.m. ET Tuesday, according to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center.

Fears Of Bioterrorism Halts Research On Mutant Bird Flu

Bioterror Fears Halt Research On Mutant Bird Flu -- BBC

Scientists who created a more deadly strain of bird flu have temporarily stopped their research amid fears it could be used by bioterrorists.

In a letter published in Science and Nature, the teams call for an "international forum" to debate the risks and value of the studies.

US authorities last month asked the authors of the research to redact key details in forthcoming publications.

A government advisory panel suggested the data could be used by terrorists.

Biosecurity experts fear a mutant form of the virus could spark a pandemic deadlier than the 1918-19 Spanish flu outbreak that killed up to 40 million people.

A Cosmic Illusion: Gravitational Lensing Helps Redraw the Map of Space -- Time

You can hardly accuse Albert Einstein of being short on imagination. The man who invented General Relativity and helped invent quantum theory probably had more creative thoughts in an hour than most folks have in a year. But one of Einstein's more intriguing scientific papers, which appeared in Science in 1936, wasn't really his idea in the first place. It came instead from a Czech electrical engineer named Rudi Mandl, who was intrigued by one of relativity's implications.

SOPA Protest Nears Zero Hour -- Politico

Internet companies and activists are hoping to join the Arab Spring and other online democracy movements by taking an estimated 7,000 websites offline Wednesday to send a message to Washington: Don’t pass a pair of anti-piracy bills.

The websites that have announced plans to go dark include Wikipedia, Mozilla, Reddit and Wordpress, but some of the most visited websites are conspicuous in their absence.

And supporters of the copyright bills dismissed the blackout as a “stunt.”

Massacre In The Hive

Massacre In The Hive: Amazing Footage Of 30 Giant Japanese Hornets Slaughtering 30,000 Tiny Honeybees To Eat Their Young -- Daily Mail

Tens of thousands are dead, hundreds more of the dying lie writhing on the battlefield, powerless to protect their children.

These horrifying and yet fascinating scenes are the highlights of a three-hour battle between just 30 giant Japanese hornets and 30,000 European honeybees.

The video, from a National Geographic documentary called Hornets From Hell, shows a full-scale attack on the honeybees' comb in order that the hornets can get at their larvae.

The Hunt for Exomoons Is Heating Up

Forget Exoplanets: The Hunt for Exomoons Is Heating Up

The universe seems almost infinitely reductive: our galaxy rotates around a central hub, planets orbit their planet stars, moons orbit their parent planets, and the odd moonlet may even orbit a moon.

Almost from the moment astronomers began finding planets around distant stars, they thus began talking about the moons that might orbit those alien worlds. It wasn't that they had any hope of discovering something as tiny as a moon: the smallest things they could find at the time were giant planets like Jupiter. But if a Jupiter happened to orbit in its star's Goldilocks Zone, where temperatures were relatively balmy, and if that Jupiter happened to have a moon about the size of Earth — not impossible, surely — then that hypothetical moon might have a chance of harboring life. That's a lot of ifs, which made talk of so-called exomoons seem like more of a marketing gimmick designed to gin up public interest in exoplanet science than a serious area of research.

A Youngster's Bright Idea Is Something New Under The Sun -- Wall Street Journal

Aidan Dwyer Took a Leaf from the Trees and Electrified International Debate

NORTHPORT, N.Y.—A new way of collecting solar energy has polarized scientists around the world and ignited fierce debate on the Internet, where the innovator in question has been called everything from an alien to the agent of a global conspiracy.

Maybe a better title would be an intellectual Hannah Montana. That's because the scientist, Aidan Dwyer, is 13 years old.

This past summer, Aidan won a national science competition with what seemed to be a bright idea: His research appeared to show that solar panels arrayed like the leaves on a tree collect sunlight more efficiently than traditional setups.

Should We Design Robots To Be More Like Velociraptors? -- Christian Science Monitor

Adding a long tails to a robot to stabilize its body could lead to far more agile search-and-rescue machines, a new study reveals.

Meat-eating dinosaurs like Velociraptor may have been quite the acrobats, using their tails to land aerial maneuvers safely, say scientists studying today's leaping lizards.

Long-tailed robots built as part of this work could help inspire a new generation of maneuverable search-and-rescue droids, the researchers add.
