US Draws Up Plans For Nuclear Drones -- The Guardian

Technology is designed to increase flying time 'from days to months', along with power available for weapons systems.

American scientists have drawn up plans for a new generation of nuclear-powered drones capable of flying over remote regions of the world for months on end without refuelling.

The blueprints for the new drones, which have been developed by Sandia National Laboratories – the US government's principal nuclear research and development agency – and defence contractor Northrop Grumman, were designed to increase flying time "from days to months" while making more power available for operating equipment, according to a project summary published by Sandia.

My Comment: While the idea of having drones fly for days on end is appealing .... the fact that it would be a nuclear power source that will be used will .... to put it bluntly .... be enough to kill the program .... regardless of the merits.

New Widespread Internet Surveillance Laws To Be Proposed In England

Internet Activity 'To Be Monitored' Under New Laws -- The Ttelegraph

Ministers are preparing a major expansion of the Government's powers to monitor the email exchanges and website visits of every person in the UK, it was reported today.

Under legislation expected in next month's Queen's Speech, internet companies will be instructed to install hardware enabling GCHQ – the Government's electronic "listening" agency – to examine "on demand" any phone call made, text message and email sent, and website accessed in "real time", The Sunday Times reported.

A previous attempt to introduce a similar law was abandoned by the former Labour government in 2006 in the face of fierce opposition.

However ministers believe it is essential that the police and security services have access to such communications data in order to tackle terrorism and protect the public.

Scanner Reveals Inner Workings Of How Our Brains Are Wired

Curvature in this image of a whole human brain turns out to be folding of 2D sheets of parallel neuronal fibers that cross paths at right angles

How Our Brains Are Wired: Scanner Reveals Inner Workings In Stunning New Detail -- The Brain

For a long time it was thought that the brain was a mass of tangled wires, but researchers recently found that its fibers are actually set up like a chess board, crossing at right-angles.

What’s more, this grid structure has now been revealed in amazing detail as part of a brain imaging study by a new state-of-the-art magnetic resonance imaging (MRI) scanner.

Van Wedeen, of Massachusetts General Hospital (MGH), who led study, said: ‘Far from being just a tangle of wires, the brain's connections turn out to be more like ribbon cables - folding 2D sheets of parallel neuronal fibers that cross paths at right angles, like the warp and weft of a fabric.

China Arrests Over Coup Rumours -- BBC

Chinese police have arrested six people and shut 16 websites after rumours were spread that military vehicles were on the streets of Beijing, officials say.

The web posts were picked up last week by media outlets around the world, amid uncertainty caused by the ouster of top political leader Bo Xilai.

The State Internet Information Office (SIIO) said the rumours had a "very bad influence on the public".

Two popular microblogs have temporarily stopped users from posting comments.

Cassini Spacecraft Captures Striking Images Of Three Saturn Moons

The jets emanate from hot fissures known as "tiger stripes" at the south pole

Cassini Spacecraft Captures Saturn Moon Geyser Images -- BBC

The Cassini spacecraft has captured striking images from flying by three moons of Saturn, including new pictures of Enceladus's gushing geysers.

Cassini made its lowest pass yet over the south pole of Enceladus, at at an altitude of 74km (46 miles).

This allowed it to "taste" the jets of water vapour and ice that the moon spews forth into space.

The Nasa probe also made relatively close flypasts of two other Saturnian satellites: Dione and Janus.

A History Of Breast Enlargements

A Brief History Of Breast Enlargements -- BBC

It is 50 years since the first breast enlargement using silicone implants. Today it rates as the second-most popular form of cosmetic surgery worldwide, undergone by 1.5 million women in 2010.

It was spring 1962 when Timmie Jean Lindsey, a mother-of-six lay down on the operating table at Jefferson Davis hospital in Houston, Texas.

Over the next two hours, she went from a B to a C cup, in an operation that made history.

"I thought they came out just perfect… They felt soft and just like real breasts," says Lindsey now aged 80.

"I don't think I got the full results of them until I went out in public and men on the street would whistle at me."

Death Of A Data Haven: Cypherpunks, WikiLeaks, And The World's Smallest Nation -- Ars Technica

A few weeks ago, Fox News breathlessly reported that the embattled WikiLeaks operation was looking to start a new life under on the sea. WikiLeaks, the article speculated, might try to escape its legal troubles by putting its servers on Sealand, a World War II anti-aircraft platform seven miles off the English coast in the North Sea, a place that calls itself an independent nation. It sounds perfect for WikiLeaks: a friendly, legally unassailable host with an anything-goes attitude.

Origins Of Domestic Cattle Traced Back 10,500 Years -- Cosmos

LONDON: All cattle are descended from as few as 80 animals that were domesticated from wild ox in the Near East some 10,500 years ago, according to a new genetic study.

An international team of scientists were able to conduct the study by first extracting DNA from the bones of domestic cattle excavated in Iranian archaeological sites. These sites date to not long after the invention of farming and are in the region where cattle were first domesticated.

Controversial Pesticide Linked To Bee Collapse -- Wired Science

A controversial type of pesticide linked to declining global bee populations appears to scramble bees’ sense of direction, making it hard for them to find home. Starved of foragers and the pollen they carry, colonies produce fewer queens, and eventually collapse.

The phenomenon is described in two new studies published March 29 in Science. While they don’t conclusively explain global bee declines, which almost certainly involve a combination factors, they establish neonicotinoids as a prime suspect.

With Google Earth No One Can Hide The Slums

With Google Earth, India Can No Longer Hide Its Shantytowns And "Slumdogs" -- Time/AP

SANGLI — Before Google Earth existed, the slums of Sangli, a city of 550,000 in southwestern India, was acknowledged on government maps by nothing more than some clumsily outlined, empty spaces. But then, from high in the sky, the eye of a satellite saw what no municipal geometer had taken the trouble to show: small islands of huts with dilapidated roofs spread throughout the city.

Thanks to the satellite images available on Google Earth, a full picture of these forgotten slums has emerged. They now have borders; they are mapped; they have an identity. And using these images, Shelter Associates, a Pune-based NGO, has begun rehabilitating the slums. For the first time in their lives, 3,900 families in Sangli are going to be moving into apartments.

Giant Solar Tornado Caught In NASA Video

Monster Solar Tornadoes Discovered -- MSNBC/Discovery News

Tempests measure width of several Earths and swirl at speeds of up to 190,000 miles

For the first time, huge solar tornadoes have been filmed swirling deep inside the solar corona — the sun's superheated atmosphere. But if you're imagining the pedestrian tornadoes that we experience on Earth, think again.

These solar monsters, measuring the width of several Earths and swirling at speeds of up to 190,000 miles per hour, aren't only fascinating structures; they may also trigger violent magnetic eruptions that can have drastic effects on our planet.

Half Of All U.S. Households Own At Least One Apple Product

The overall ownership rate is 1.6 Apple products per American household, according to a new survey.

Half Of U.S. Households Own At Least One Apple Product -- CNN

(Mashable) -- Apple has taken firm root in America. Just over half of all households in the country own at least one Apple product, a new survey says, showing just how far the reach of the company has come in the last decade.

At the turn of the 21st century, Apple was in rough shape. It had narrowly avoided bankruptcy, and Steve Jobs' return as CEO a few years earlier was turning the company around, but the market share of its products -- then almost exclusively Mac computers -- was dismal, at about 2% worldwide.

Fossil Raindrops Reveal Ancient Atmosphere -- Cosmos

BRISBANE: The fossilised marks of raindrops that fell 2.7 billion years ago in South Africa have revealed the composition of the Earth's early atmosphere.

According to a new study published in Nature today, the early Earth had an atmosphere with similar air pressure to the present day, but much higher levels of greenhouse gases. The findings, from a time when the Earth already had abundant microbial life, should improve our knowledge of what kinds of extrasolar planets might support life.
