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.

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.

Is Sex Possible During Pregnancy

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.

My Comment: The focus of the media is on the Egyptian Museum in Cairo, and efforts to protect it. But the fact is that there are many more museums all across Egypt, and reports are now coming in that they are being looted. To say that this is a catastrophe is an understatement. Regardless of what is happening politically, years from now Egypt will be looking at what is happening today as a dark day in which a good portion of its historical past was looted and stolen.

Rewriting History Of Man As A Global Species

Out Of Africa: Stone Tools Rewrite History Of Man As A Global Species -- The Independent

A stone-age archaeological site in the Arabian peninsula has become the focus of a radical theory of how early humans made the long walk from their evolutionary homeland of Africa to become a globally-dispersed species.

Scientists have found a set of stone tools buried beneath a collapsed rock shelter in the barren hills of the United Arab Emirates that they believe were made about 125,000 years ago by people who had migrated out of eastern African by crossing the Red Sea when sea levels were at a record low.

New Handheld Melanoma Scanner Instantly Identifies Skin Cancers With Laser Light -- Popular Science

Yeah, you’ve been thinking about getting that thing checked out, but it’s just a mole right? Such is the problem with melanoma; it’s tough to know which spots on the skin are benign and which could be the hallmark of early-stage skin cancer. Most dermatologists still decide which moles require a biopsy by good old fashioned eye-balling, but a new device developed by researchers at British Colombia Cancer Agency (BCCA) could remove that guesswork, using a handheld laser to quickly identify problem spots that require closer examination.

ScienceDaily (Jan. 31, 2011) — So you think global warming is a big problem? What could happen if a 25-million-ton chunk of rock slammed into Earth? When something similar happened 65 million years ago, the dinosaurs and other forms of life were wiped out.

"A collision with an object of this size traveling at an estimated 30,000 to 40,000 mile per hour would be catastrophic," according to NASA researcher and New York City College of Technology (City Tech) Associate Professor of Physics Gregory L.

For Veterans, Road to Mental Health May Begin at the Bar -- Live Science

Connecting struggling veterans to the mental health services they need is an ongoing challenge. Now, a new study finds that the process could start with a sympathetic bartender.

The exploratory study found that bartenders at Veterans of Foreign Wars (VFW) clubs could help identify veterans in trouble and direct them to mental health professionals. Brief and inexpensive training for these bartenders would widen the safety net for veterans in need of care, said study researcher Keith Anderson, a professor of social work at Ohio State University
