Standing At 11 Feet: World's Largest Known Bear Unearthed -- Live Science

The fossils of the largest known bear to have ever lived have been found, a giant that was the most powerful land carnivore of its time, scientists said.

The remains were unearthed during the construction of a hospital in La Plata City, Argentina. It was a South American giant short-faced bear (Arctotherium angustidens), the earliest and largest member of its genus (its group of species of bears). This titan lived between 2 million to 500,000 years ago, with its closest living relative being the spectacled bear (Tremarctos ornatus) of South America.

Cyber War Rules Of Engagement Being Proposed

Proposal For Cyber War Rules Of Engagement -- BBC

The world needs cyber war "Rules of Engagement" to cope with potentially devastating cyber weapons, Russian and US experts will tell world leaders at a security conference on Friday.

The cyber proposal, seen exclusively by Newsnight, comes from the influential EastWest Institute in New York.

It describes "rendering the Geneva and Hague conventions in cyberspace".

Cyber security is on the agenda at the annual Munich Security Conference for the first time this year.

Space So Full Of Junk That A Satellite Collision Could Destroy Communications On Earth -- The Telegraph

Space is so littered with debris that a collision between satellites could set off an “uncontrolled chain reaction” capable of destroying the communications network on Earth, a Pentagon report warned.

The volume of abandoned rockets, shattered satellites and missile shrapnel in the Earth’s orbit is reaching a “tipping point” and is now threatening the $250 billion (£174bn) space services industry, scientists said.

A single collision between two satellites or large pieces of “space junk” could send thousands of pieces of debris spinning into orbit, each capable of destroying further satellites.

What You Need to Know About Pregnant Sex -- Live Science

Prospective parents can breathe a sigh of relief: According to the latest research, sex during pregnancy is almost always safe.

The latest primer for physicians on the topic, published today (Jan. 31) in the Canadian Medical Association Journal, advises pregnant women and their partners to engage in sex according to the couple's comfort level. The only exception is in the case of high-risk pregnancies. In those cases, sex may sometimes carry risk, the authors wrote, though the evidence is limited.

5,000 Years Of Egyptian Antiquities Are Now Being Looted Across Egypt

Egypt's Antiquities Fall Victim To The Mob -- Wall Street Journal

When Zahi Hawass, the secretary general of the Supreme Council of Antiquities, came to work at the Egyptian Museum on Saturday, he found that looters had broken in and beheaded two mummies—possibly Tutankhamun's grandparents—and looted the ticket booth. Reports indicate that middle-class Egyptians, the tourism police and later the military secured the museum. But now it appears that many other museum's and storehouses have been looted, along with archaeological sites. A vast, impoverished underclass seems less taken with either the nationalist narrative of Egyptian greatness that stretches back to the pharaohs, or the intrinsic value of antiquities for all humanity, and more intrigued by the possibility of gold and other loot. For his part, Mr. Hawass has now been appointed state minister for antiquities by President Hosni Mubarak.

It all depends on the size, physical fitness and hydration of the person in question, but it’s possible to sweat buckets before heatstroke sets in and we pass out. After all, there are about three million sweat glands on the human body (the highest concentration is on our palms), and the average person aggressively working out perspires about 0.7 to 1.5 liters per hour. Theoretically, if we were attached to a treadmill and pumped full of liquids, it’s possible to keep sweating forever.

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.”

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.

My Comment: A perfect storm of drought, floods, and failing crops is probably going to give many countries a lot of grief this year when it comes to the price of food supplies.

Humans Left Trees 4.2 Million Years Ago -- Discovery News

Wrist bones of human ancestors reveal when humans switched from living in trees to on the ground.

* Fossilized wrist bones suggest humans switched from trees to a terrestrial lifestyle between 4.2 and 3.5 million years ago.
* Tree dwellers experience more stress on the pinky side of their hands while terrestrial species tend to load more stress on the thumb side.
* The timing of the switch coincides with climate and habitat changes and a shift in diet.

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.

Japan On Alert After Volcano's Biggest Eruption In 50 Years

Force of nature: Lightning strikes as Shinmoedake erupts, scattering ash and rocks across a wide swathe of southern Japan

Lightning And Fire: Japan On Alert After Volcano's Biggest Eruption In 50 Years -- The Daily Mail

A one-mile cordon has been established around a volcano on Mount Kirishima after it erupted scattering rocks and ash across southern Japan and sending smoke billowing 5,000ft into the air.

The Meteorological Agency raised the volcanic alert to level 3 as ash today continued to spew from Shinmoedake on Japan's southernmost main island of Kyushu, and residents have been banned from going within a mile of the volcano following its worst eruption in 50 years.

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.
