Will The U.S. Get An "Internet Kill Switch"?

After Egypt, Will U.S. Get 'Internet Kill Switch'? -- PC Magazine

With reports of Egypt's government completing shutting down the Internet in the country, talk about an "Internet kill switch" bill in the U.S. has reemerged. Could it happen here?

The bill in question is the Protecting Cyberspace as a National Asset Act of 2010, a cyber-security measure introduced in June by Sen. Joseph Lieberman. It was an over-arching cyber-security measure that, among other things, would create an office of cyberspace policy within the White House and a new cyber-security center within the Homeland Security Department.

The Future Of Wine: We Need New Breeds Of Grape -- Popular Science

When news broke last week that archaeologist had unearthed a 6,000-year-old winemaking operation in an Armenian cave, many took it as occasion to pat ourselves on the backs—after all, it’s proof that early humans were more civilized than previously thought, evolved creatures that we are. Unfortunately, in the intervening years our grapes haven’t evolved much at all, leaving our winemaking varieties—most of which have been developed from a single species—extremely susceptible to disease and pathogens.

Dinosaurs Survived Mass Extinction by 700,000 Years, Fossil Find Suggests -- Science Daily

ScienceDaily (Jan. 27, 2011) — University of Alberta researchers determined that a fossilized dinosaur bone found in New Mexico confounds the long established paradigm that the age of dinosaurs ended between 65.5 and 66 million years ago.

The U of A team, led by Larry Heaman from the Department of Earth and Atmospheric Sciences, determined the femur bone of a hadrosaur as being only 64.8 million years old. That means this particular plant eater was alive about 700,000 years after the mass extinction event many paleontologists believe wiped all non-avian dinosaurs off the face of earth, forever.

In Vino Veritas: Wine Cups Tell History of Athenian Life -- Live Science

Over centuries, the ancient Athenian cocktail parties went full circle, from a practice reserved for the elite to one open to everyone and then, by the fourth century B.C., back to a luxurious display of consumption most could not afford.

The wine cups used during these gatherings, called symposia, reflect this story, according to Kathleen Lynch, a University of Cincinnati professor of classics.

Lack Of Diversity In Grapes Raises Concerns

(Click on Image To Enlarge)

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.

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.
