Why Men And Women Get Jealous For Different Reasons

From Times Online:

Cheating on a spouse or significant other is sure to cause feelings of jealousy and hurt in the spurned partner.

But men and women differ on what part of cheating they think is the worst: Men tend to be more bothered by sexual infidelity, while most women are bothered more by emotional infidelity.

The prevailing explanation for this difference is the unique evolutionary roles played by men and women, but a new study suggests that it has more to do with the types of attachments people form in relationships.

Superfast Bullet Trains Are Finally Coming To The U.S.

From Wired Science:

Believe it: Bullet trains are coming. After decades of false starts, planners are finally beginning to make headway on what could become the largest, most complicated infrastructure project ever attempted in the US. The Obama administration got on board with an $8 billion infusion, and more cash is likely en route from Congress. It’s enough for Florida and Texas to dust off some previously abandoned plans and for urban clusters in the Northeast and Midwest to pursue some long-overdue upgrades. The nation’s test bed will almost certainly be California, which already has voter-approved funding and planning under way. But getting up to speed requires more than just seed money. For trains to beat planes and automobiles, the hardware needs to really fly. Officials are pushing to deploy state-of-the-art rail rockets. Next stop: the future.

New Battlefield Drug May Save Soldiers Dying From Blood Loss

Battlefield Blood Loss Combat medics work through the "blood lab" at the Department of Combat Medic Training at Fort Sam Houston, Texas. U.S. Army

From Popular Science:

People who suffer massive blood loss automatically go into shock as a stopgap measure, but can eventually die if their bodies stay in shock for too long. Now a drug used to treat epilepsy could reverse all that and boost survival rates for horrifically injured people, especially wounded soldiers far from any extra blood supplies. New Scientist reports on a new study of the drug that involved porkers.

My Comment: Blood loss and the accompanying shock is what kills people in trauma situations. Any advancement in this filed of medicine will be a godsend not only for the soldiers in the battlefield, but also to everyone else in society.

Water Vapour Caused One-Third Of Global Warming In 1990s, Study Reveals

A 10% drop in water vapour, 10 miles up has had an effect on global warming over the last 10 years, scientists say. Photograph: Getty

From The Guardian:

Experts say their research does not undermine the scientific consensus on man-made climate change, but call for 'closer examination' of the way computer models consider water vapour.

Scientists have underestimated the role that water vapour plays in determining global temperature changes, according to a new study that could fuel further attacks on the science of climate change.

The research, led by one of the world's top climate scientists, suggests that almost one-third of the global warming recorded during the 1990s was due to an increase in water vapour in the high atmosphere, not human emissions of greenhouse gases. A subsequent decline in water vapour after 2000 could explain a recent slowdown in global temperature rise, the scientists add.

From The Daily Mail:

How the Moon was created and came to orbit the Earth has long puzzled scientists.

The most commonly held theory is that when the solar system was first formed, an object collided with Earth, knocking off a chunk of rock that fell into orbit around it.

But now two scientists have come up with a new explanation. They believe the Moon did not break away from the Earth because of an impact or an explosion in space, but because of a nuclear explosion on Earth itself.

From Nature News:

Mysterious changes in the stratosphere may have offset greenhouse effect.

A puzzling drop in the amount of water vapour high in the Earth's atmosphere is now on the list of possible culprits causing average global temperatures to flatten out over the past decade, despite ever-increasing greenhouse-gas emissions.

Although the decade spanning 2000 to 2009 ranks as the warmest on record, average temperatures largely levelled off following two decades of rapid increases. Researchers have previously eyed everything from the Sun and oceans to random variability in order to explain the pause, which sceptics have claimed shows that climate models are unreliable.

From Popular Science:

Military simulators that resemble video games have obvious training benefits for warfighters, but U.S. Navy scientists also say that video games can boost brainpower and produce cognitive improvements that last up to two and a half years.

The Office of Naval Research (ONR) hopes that video game-like training can help warfighters hone their "fluid intelligence," or ability to confront and solve new problems. Such research feeds into a new sense that the human brain can continue to adapt and improve itself beyond early adulthood, and may allow soldiers to better adjust to the changing tactics and environment of the modern-day battlefield.

From Scientific American:

Toyota, the world's largest automaker, has suspended sales of certain models and recalled millions of older ones as its engineers search for the elusive source of a sticky—and dangerous—accelerator problem

During the past few days, Toyota Motor Corp., has taken the unprecedented step of halting sales in the U.S., Europe and China of some of its most popular car and truck models. The reason: potential defects that cause the vehicles to speed up without warning and run out of control. The move follows a huge (and growing) recall of older Toyota vehicles last week. Safety Research and Strategies, based in Rehoboth, Mass., has reportedly implicated the sudden unintended acceleration problem to 2,274 incidents in Toyota vehicles, causing 275 crashes and at least 18 fatalities since 1999.

Science Daily (Jan. 27, 2010) — The paper, by Professor João Zilhão and colleagues, builds on his earlier research which proposed that, south of the Cantabro-Pyrenean mountain chain, Neanderthals survived for several millennia after being replaced or assimilated by anatomically modern humans everywhere else in Europe.

Although the reality of this 'Ebro Frontier' pattern has gained wide acceptance since it was first proposed by Professor Zilhão some twenty years ago, two important aspects of the model have remained the object of unresolved controversy: the exact duration of the frontier; and the causes underlying the eventual disappearance of those refugial Neanderthal populations (ecology and climate, or competition with modern human immigrants).

From Live Science:

Physicists may be one step closer to achieving a form of clean energy known as nuclear fusion, which is what happens deep inside the cores of stars.

A recent experiment with a giant levitating magnet was able to coax matter in the lab to extremely high densities — a necessary step for nuclear fusion.

When the density is high enough, atomic nuclei — the protons and neutrons of atoms — literally fuse together, creating a heavier element. And if the conditions are right that fusion can release loads of energy.
