Did An 8th Century Gamma Ray Burst Irradiate Earth? -- Science Daily 

Jan. 21, 2013 — A nearby short duration gamma-ray burst may be the cause of an intense blast of high-energy radiation that hit the Earth in the 8th century, according to new research led by astronomers Valeri Hambaryan and Ralph Neuhӓuser.

The two scientists, based at the Astrophysics Institute of the University of Jena in Germany, publish their results in the journal Monthly Notices of the Royal Astronomical Society.

Mars Scientists Find ‘Strongest Evidence Yet’ That Planet May Have Supported Life -- National Post

Scientists believe they may have found the ‘strongest evidence yet’ that Mars may have supported life, but it’s unlikely in the form most people would recognize.

New research published today in the journal Nature Geoscience suggests a team of scientists could have discovered the ingredients of life in a huge crater up to 5km below the planet’s surface.

The McLaughlin crater, which was made by a meteorite which smashed into Mars, is described as an area of interest for the team, led by London’s Natural History Museum and the University of Aberdeen in Scotland.

Deodorants: Do We Really Need Them? -- Science Daily

 Jan. 17, 2013 — New research shows that more than 75 per cent of people with a particular version of a gene don't produce under-arm odour but use deodorant anyway.

The study was based on a sample of 6,495 women who are part of the wider Children of the 90s study at the University of Bristol. The researchers found that about two per cent (117 out of 6,495) of mothers carry a rare version of a particular gene (ABCC11), which means they don't produce any under-arm odour.

9 Interesting Facts On The U.S. Pentagon

The Pentagon (Wikipedia

9 Things You May Not Know About the Pentagon -- History

On January 15, 1943, work was completed on the new headquarters for the U.S. War Department (the modern-day Department of Defense) in Arlington, Virginia. The massive complex, commonly known as the Pentagon, was built to house the nearly 30,000 defense workers tasked with helping America win World War II. With more than 17 miles of corridors, it remains one of the largest office buildings in the world, and has become a symbol—for better and for worse—of military might. Eighty years after its completion, here are nine things you may not know about the Pentagon.

Where Did Europe`s Jews Come From?

Jews throw stones at the sea to symbolically cast off their sin on September 20, 2009 in Nice, France, as part of Rosh Hashanah, the Jewish New Year. Jews of European origin are a mix of ancestries, with many hailing from tribes in the Caucasus who converted to Judaism and created an empire that lasted half a millennium, according to a gene study published on Thursday. 

Gene Study Settles Debate Over Origin Of European Jews -- France24 

AFP - Jews of European origin are a mix of ancestries, with many hailing from tribes in the Caucasus who converted to Judaism and created an empire that lasted half a millennium, according to a gene study published on Thursday.

The investigation, its author says, should settle a debate that has been roiling for more than two centuries. Jews of European descent, often called Ashkenazis, account for some 90 percent of the more than 13 million Jews in the world today. According to the so-called Rhineland Hypothesis, Ashkenazis descended from Jews who progressively fled Palestine after the Moslem conquest of 638 AD.

My Comment: In short .... they came from the Middle East and the Caucasus.

Why Wolves Cannot Be Tamed

Why Dogs Can Be Tamed But Wolves Cannot -- Science 2.0 

Wolves and dogs are genetically very similar, so why did dogs become "man's best friend" while wolves remain wild? Kathryn Lord at the University of Massachusetts Amherst suggests the different behaviors are related to the animals' earliest sensory experiences and the critical period of socialization.

Not much is known about sensory development in wolf pups and assumptions are usually extrapolated from what is known for dogs - but there are significant differences in early development between wolf and dog pups, chief among them timing of the ability to walk.

Archaeologists Believe No Spitfires Buried In Burma -- BBC 

Archaeologists hunting for World War II Spitfires in Burma believe there are no planes buried at the sites where they have been digging, the BBC understands.

The archaeologists have concluded that evidence does not support the original claim that as many as 124 Spitfires were buried at the end of the war, the BBC's Fergal Keane reports.

Wargaming.net, the firm financing the dig, has also said there are no planes. But project leader David Cundall says they are looking in the wrong place.

Iran Strengthened Cyber Capabilities After Stuxnet: U.S. General -- Reuters

(Reuters) - Iran responded to a 2010 cyber attack on its nuclear facilities by beefing up its own cyber capabilities, and will be a "force to be reckoned with" in the future, a senior U.S. Air Force official told reporters on Thursday.

General William Shelton, who heads Air Force Space Command and oversees the Air Force's cyber operations, declined to comment about Iran's ability to disrupt U.S. government computer networks, but said Tehran had clearly increased its efforts in that arena after the 2010 incident.

While no government has taken responsibility for the Stuxnet computer virus that destroyed centrifuges at Iran's Natanz uranium enrichment facility, it was widely reported to have been a U.S.-Israeli project.

Germany Unveils It's Own 'Star Wars' Laser

The system is currently mounted of a series of large metal containers. However, the firm is developing a smaller, portable version that could easily be transported to the battlefront. 

Germans Unveil 'Star Wars' Laser That Can Shoot A Drone Out Of The Sky From TWO MILES Away And Cut Through A Steel Girder At 700 Yards -- Daily Mail 

* High powered laser is powerful enough to cut through a steel girder from 1km away
* System is so accurate it could track and destroy an 82mm ball bearing designed to replicate a mortar round
* German firm hopes to create a portable version that could be used on the battlefield

One of the most powerful laser weapons ever fired has successfully shot drones out of the sky from two miles away.

The groundbreaking weapon uses a high powered 50kW laser, and is powerful enough to cut through a steel girder from 1km away, yet accurate enough to hit a target the size of a mortar round.

The Role Of Soot In Climate Change

The burning of wood is a major source of black carbon the world over. 

Climate Change: Soot's Role Underestimated, Says Study -- BBC 

Black carbon, or soot, is making a much larger contribution to global warming than previously recognised, according to research.

Scientists say that particles from diesel engines and wood burning could be having twice as much warming effect as assessed in past estimates.

They say it ranks second only to carbon dioxide as the most important climate-warming agent. The research is in the Journal of Geophysical Research-Atmospheres.

Black carbon aerosols have been known to warm the atmosphere for many years by absorbing sunlight. They also speed the melting of ice and snow.

Okay, we know we're a little late on this, but that's because there was so much amazing stuff to sift through! In 2012, robotic technology made some huge leaps forward. We put the world's most sophisticated planetary rover on Mars using a daring--and precise--robotic delivery system. We launched marine robots capable of taking on hurricanes and rebuilding damaged coral reefs. We saw four-legged robots set new land speed records, and winged, autonomous robots strut their potentially lethal stuff on the deck of an aircraft carrier.

Pacific Bluefin Tuna Population Has Dropped By 96 Percent -- Popsci.com 

The dark side of sushi's surge in popularity. For the Pacific bluefin tuna, sitting at the popular kids' table sure isn't paying off. The stock of the fish is at historically low levels and is being dangerously overfished, a new report shows. Fisheries scientists from the International Scientific

Committee to Study the Tuna and Tuna-Like Species of the North Pacific Ocean estimate that the Pacific bluefin population has declined from its unfished level by more than 96 percent. The report warns that stock levels likely won't improve by extending the current fishing levels. All the world's scrombrids -- a family that includes tunas and mackerels -- are on the endangered list.

Lasers: Asia’s Coming “Sci-Fi” Arms Race -- J. Michael Cole, The Diplomat

True to Newton’s Third Law on Motion, weapons development is a constant battle of adaptation with one side unveiling new technology only for the other to respond with countermeasures. Very few platforms in recent years have been as influential or attracted as much publicity as have unmanned aerial vehicles (UAV), which have greatly enhanced surveillance capability while giving their owners the ability to target enemies thousands of miles away at relatively little cost.

The Next Crews With The Right Stuff Will Work For Private Companies, Not NASA -- Popular Science  

Spaceship builders will assume the flight risk first with their own test pilot employees.

 Private companies are already sending cargo into space on their own, but no one is sending any people yet--for now, Americans can only get to space with help from the Russians. When commercial aerospace firms do start delivering Americans to space for the first time, they will not be wearing NASA meatball patches on their breast pockets.

Instead, commercial test pilots employed by spaceship builders will fly the first crewed missions, according to NASA officials. The space agency is letting the private firms bear that risk before exposing its own astronauts to a privately built ship.

The Oldest Star In The Universe: Astronomers Find HD 140283 Is At Least 13.2 billion Years Old -- Daily Mail 

* Star known as HD 140283 has been observed for more than a century
 * It formed within the first 600 million years of the Big Bang
 * Earth lies just 186 light years away from the oldest known star

More than a century after it was first observed by astronomers a star has been identified as the oldest yet seen in the universe.

The star is just 186 light years away from Earth and is at least 13.2 billion years old, and quite possibly many millions of years older than that.

The Big Bang is calculated by scientists to have taken place about 13.77 billion years ago and the star, known only as HD 140283, was among the earliest stars to form.

New Rifle Technology Can Turn A Novice Into A Dangerous Sniper

Smart' hunting rifle makes up for jittery aim 

Using state of the art digital range finders and a very smart trigger, the TrackingPoint rifle can make a sharpshooter out of anyone, including NBCNews.com's Wilson Rothman. 

Futuristic Rifle Turns Novice Into Sharpshooter -- NBC 

It all goes back to "Top Gun." In the heads-up display on Maverick's Tomcat, you can see a computer compensate for human aim with precision laser guidance and careful calculations. How long before that technology made its way to to a conventional hunting rifle? It's here now, with a price tag of $17,000 to $21,000.

We came to Las Vegas the first week of January, the way we always do, for the Consumer Electronics Show. The vast trade show features over 3,300 exhibitors, and covers 1.9 million square feet. But there are no shooting ranges at CES. To check out TrackingPoint, we had to drive out to the hills outside of town.
