Lack Of Sex Among Grapes Tangles A Family Vine -- New York Times

For the last 8,000 years, the wine grape has had very little sex. This unnatural abstinence threatens to sap the grape’s genetic health and the future pleasure of millions of oenophiles.

The lack of sex has been discovered by Sean Myles, a geneticist at Cornell University. He developed a gene chip that tests for the genetic variation commonly found in grapes. He then scanned the genomes of the thousand or so grape varieties in the Department of Agriculture’s extensive collection.

Much to his surprise he found that 75 percent of the varieties were as closely related as parent and child or brother and sister. “Previously people thought there were several different families of grape,” Dr. Myles said. “Now we’ve found that all those families are interconnected and in essence there’s just one large family.”

Thunderstorms Create Beams Of Antimatter -- Cosmos

SYDNEY: A space-based telescope has detected beams of antimatter shooting out the top of thunderstorms, in what has been described as an “amazing curiousity of nature”.

The data was collected from NASA's Fermi Gamma Ray SpaceTelescope. In some cases the thunderstorms were thousands of kilometres away, and the beams were detected only after they had travelled along the Earth’s magnetic field and collided with the spacecraft.

Ten Endangered-Species Battles

10 Critical Endangered-Species Battles -- Wired Science

In theory, decisions about flora and fauna habitat are purely scientific. In practice, they're political. And that, in a nutshell, is the reality of the Endangered Species Act, passed in 1973 as part of a historic wave of legislation that both protects America's environmental heritage and provides a framework for settling conflicts.

Some say it does too little; others, that it intrudes too much. The arguments go 'round and 'round, and underscore a fundamental truth: In the Anthropocene Era, people decide nature's fate.

Food Inflation Expected To Reach 50% For Some Countries This Year

The world is facing a commodities crisis that could leave millions unable to afford the rising costs of food as population levels soar

Food Prices To Rocket By 50% As Global Hunger Epidemic Causes Riots And Famines -- The Daily Mail

* 'Perfect storm' of issues will bring widespread starvation if nothing is done
* Food prices to rise by 50 per cent over the next decade
* GM crops will be needed to feed the world
* Global population to grow to 9billion by 2050

The cost of food will soar by 50 per cent over the next few decades as the world becomes racked by famine, mass migrations and riots, experts have warned.

The increase will be triggered by the exploding world population, rising cost of fuel and increased competition for water, according to a leading Government think-tank.

Spiralling food prices will push hundreds of millions of people into hunger, trigger mass migration and spark civil unrest, the report warned.

Marines in Afghanistan Find That Solar Panels Save Soldiers' Lives -- Popular Science

A battalion of Marines in Afghanistan is going green, using solar panels to reduce their energy consumption and thereby reduce the things they carry — and even save lives.

The Marines and sailors of 3rd Battalion, 5th Marine Regiment arrived last October at Forward Operating Base Jackson, outside Sangin, Afghanistan, with an array of solar equipment. The battalion’s generators typically use more than 20 gallons of fuel a day, but the Marines have cut that to 2.5 gallons a day, according to Staff Sgt. David Doty, who maintains the gear.

Potential 'Cure' for Type 1 Diabetes? -- Science Daily

ScienceDaily (Jan. 27, 2011) — Type 1 diabetes could be converted to an asymptomatic, non-insulin-dependent disorder by eliminating the actions of a specific hormone, new findings by UT Southwestern Medical Center researchers suggest.

These findings in mice show that insulin becomes completely superfluous and its absence does not cause diabetes or any other abnormality when the actions of glucagon are suppressed. Glucagon, a hormone produced by the pancreas, prevents low blood sugar levels in healthy individuals. It causes high blood sugar in people with type 1 diabetes.

From Live Science:

Robots that evolved from crawling babies into upright adults could help pave the way for better bots.

Using a computer program, researchers at the University of Vermont simulated a population of naive "baby" robots. The robots had to complete various tasks in their virtual environment, such as finding objects and walking toward them. Those robots that performed poorly got deleted, while the best-performing ones remained "alive."

The robots that changed their body forms (like tadpoles growing into frogs) learned to walk more rapidly and developed the most stable gait, the researchers found.

WikiLeaks Rival Launches New Secret-Spilling Site -- Washington Post

DAVOS, Switzerland -- A former member of the group that created WikiLeaks has launched a rival website with the aim of giving whistleblowers more control over the secrets they spill.

Daniel Domscheit-Berg says the new platform called OpenLeaks will allow sources to choose specifically who they want to submit documents to anonymously, such as to a particular news outlet.

He told reporters Friday that the site will begin testing in several weeks and hopes it will be fully operational later this year.

Man's Migration Out Of Africa More Complicated Than Thought

Ancient Tools May Mark Earlier Path Out Of Africa -- Wired Science

The bodies are still missing, but a prehistoric toolkit discovered in the United Arab Emirates has led some archaeologists to propose a more complex scenario for humanity’s emigration out of Africa.

Uncovered at a Jebel Faya rock shelter, just west of the Straits of Hormuz at the mouth of the Persian Gulf, the tools are 125,000 years old. Previous estimates placed the dispersal of modern humans from North Africa around 70,000 years ago. If correct, this new study indicates that humans in eastern Africa left earlier, and traveled to Arabia.

Efficiency Could Cut World Energy Use Over 70 Per Cent -- New Scientist

Simple changes like installing better building insulation could cut the world's energy demands by three-quarters, according to a new study.

Discussions about reducing greenhouse gas emissions usually concentrate on cleaner ways of generating energy: that's because they promise that we can lower emissions without having to change our energy-hungry ways. But whereas new generation techniques take years to come on stream, efficiency can be improved today, with existing technologies and know-how.

Using Plants In The Fight Against Terrorism

The Latest Weapon In The Fight Against Terrorism: How Scientists Have Developed Plants That Can Detect Bombs -- The Daily Mail

They provide us with food and are pretty to look at, and now they may even save out lives.

For unlikely as it may seem, scientists have developed plants that can detect bombs.

They have taught plant proteins to change colour when in the presence of certain chemicals.

The implications of the study are not hard to see - ringing an airport security gate, for instance, with such plants could prove a lifesaver should a terrorist approach with an explosive and a whole wall of leaves turn white.

Climate Change Means We Will Be Skiing In Yorkshire Rather Than Sunbathing Under Palm Trees, Experts Warn -- The Telegraph

We are more likely to be skiing in Yorkshire than basking under palm trees, a leading climate change expert has warned as global warming will actually lead to Britain getting colder.

Dr Simon Boxall, of the National Oceanography Survey, said that while the planet as a whole will get much warmer, this country will see temperatures plunge as the ocean currents and weather patterns around the world change.

At the moment north west Europe, particularly Britain, is warmer than it should be because of the effect of the North Atlantic Drift bringing warm water from the Tropics.

This then warms sea breezes which keep temperatures mild on land.

Finally, E-Paper Screens Made Of Real Paper! -- Popular Mechanics

In December, electrical engineers at the University of Cincinnati reinvented the wheel. By applying electric fields to nonglass materials, they discovered they could make an e-paper display screen using the unlikeliest of materials—paper.

This discovery has big implications for the future of the screen: Making a display out of regular old paper could maximize affordability, decrease environmental impact and also save space, since a paper screen has the potential to roll up and pull out. So is it time to throw out our retro flatscreens and make room for paper television? Not just yet. The future is exciting, but looking at the essential components of a display screen reveals some big roadblocks on the way to shoving a 78-inch screen into your cup holder.
