Orange Dwarf Confirmed To Be On Collision Course With Earth

Gliese 710 Hi there, neighbor! NASA

From Popular Science:

Our solar system's 'hood may get a bit rougher sometime during the next 1.5 million years. An astronomer has given an 86 percent chance for a neighboring star to smash into the frozen Oort Cloud surrounding the outskirts of the solar system, and may scatter some comets toward Earth, Technology Review reports.

From New Scientist:

A network of ancient rivers and streams that once flowed beneath Australia's Simpson desert – famed for its dune fields – has been mapped in a new study. The map could lead the way to valuable minerals and water resources in this drying continent.

Michael Hutchinson and John Stein of the Australian National University in Canberra extracted data from previous ground surveys to map an ancient river system 35 metres below the surface of the desert. They think the channels are among the world's oldest at 50 million years old, when the now barren land would have been lush and well watered.

From The Telegraph:

Towering 10 feet into the air and weighing more than half a ton, it was the biggest bird that ever lived until French colonists wiped it out more than three hundred years ago.

But the giant elephant bird of Madagascar could be resurrected after scientists discovered how to extract DNA from ancient egg shells.

Genetic material from the bird along with extinct emus of Australia and moas of New Zealand have been collected by a new technique.

Traces Of The Past: Computer Algorithm Able To 'Read' Memories

To explore how memories are recorded, researchers showed volunteers three short films and asked them to memorize what they saw. The films were very simple, sharing a number of similar features -- all included a woman carrying out an everyday task in a typical urban street, and each film was the same length, seven seconds long. For example, one film showed a woman posting a letter. (Credit: Wellcome Trust Centre for Neuroimaging at UCL)

From Science Daily:

Science Daily (Mar. 11, 2010) — Computer programs have been able to predict which of three short films a person is thinking about, just by looking at their brain activity. The research, conducted by scientists at the Wellcome Trust Centre for Neuroimaging at UCL (University College London), provides further insight into how our memories are recorded.

Oil Production To Peak In 2014, Scientists Predict


From Live Science:

Predicting the end of oil has proven tricky and often controversial, but Kuwaiti scientists now say that global oil production will peak in 2014.

Their work represents an updated version of the famous Hubbert model, which correctly predicted in 1956 that U.S. oil reserves would peak within 20 years. Many researchers have since tried using the model to predict when worldwide oil production might peak.

MoD Trains Army To Fight Using Sophisticated Video Games



From The Daily Mail:


Poised with a rifle in the desert terrain, a British soldier dives for cover as he comes under enemy fire. But amazingly he comes to no harm... because he's sitting in a Bristol armed forces base 3,500 miles from the front line in Afghanistan.

Soldiers are being prepared for combat using a newly upgraded virtual training system. Called Op JCOVE, it runs on PCs and laptops and allows soldiers to experience a wide range of scenarios both in vehicles and on foot.

2011 Ford F-Series Super Duty Test Drive


From Popular Mechanics:

PHOENIX, Ariz.—Has the definition of leadership in the heavy-duty/super-duty truck segment changed since the last time Ford, Chevrolet/GMC, and Dodge brought out new truck bruisers? Make no mistake: Horsepower, torque, towing and payload are still the primary fields of battle for winning over ranchers, construction workers and contractors. But we can add another event to the heavy-duty Olympics, according to those customers—fuel economy. That's right. Even with gas and diesel comfortably below $3.00 a gallon in most parts of the U.S., fuel economy has become the new torque when it comes to impressing customers. Ford, in fact, named fuel economy as its leading concern when it set out to build a new diesel engine after severing its relationship with diesel-engine supplier Navistar. The results are surprising, and may well entice Dodge and Chevy owners.

From Popular Science:

A new study shows that blasted asteroids could re-form, Terminator-style.

Pop quiz. An asteroid the size of Manhattan is hurtling towards Earth, its impact is sure to result in mass extinction and the destruction of humanity as we know it. What do you do?

The traditional answers would be "blow it up". But new research from Los Alamos National Lab and the University of California, Santa Cruz, shows that if the asteroid isn't moving fast enough, or if the nuke isn't big enough, the asteroid will pull itself back together, T-1000-style, within a matter of hours.

Obesity: Food Kills, Flab Protects

From The New Scientist:

OBESITY kills, everyone knows that. But is it possible that we've been looking at the problem in the wrong way? It seems getting fatter may be part of your body's defence against the worst effects of unhealthy eating, rather than their direct cause.

This curious insight comes at the same time as several studies distancing obesity itself from a host of diseases it has long been blamed for, including heart disease and diabetes.

Why The Chile Earthquake Aftershock Was So Big



From Live Science:

The whopping 7.2-magnitude aftershock that rattled Chile again today is nothing unusual following such a large original earthquake, scientists say.

The aftershock, which struck at about 11:40 am local time, may sound surprisingly strong, given that it is bigger than the original earthquake that decimated Haiti in January, but it wasn't unexpected to scientists, said Don Blakeman, a geophysicist with the United States Geological Survey.

Absent-Mindedness Is A Middle-Aged Male Problem, Research Shows

A study has shown that older men are more susceptible to absent-mindedness than women. Photograph: Toby Melville/Reuters

From The Guardian:

Women come out best in listening and recollection tests in study by University of London's Institute of Education.

It's been an endless source of aggravation between the sexes; how can men so easily forget birthdays, anniversaries, and even friends' names?

Not, it seems, because they cannot be bothered to remember. Research suggests that, in middle age at least, absent-minded-ness is a particularly male problem.
