The Unromantic Truth About Why We Kiss - To SpreadGgerms

Pucker up: Kissing the same person for about six months provides optimum protection from potentially deadly germs, says Dr Colin Hendrie

From The Daily Mail:

It is an international symbol of love and romance. But the kiss may have evolved for reasons that are far more practical - and less alluring.

British scientists believe it developed to spread germs.

They say that the uniquely human habit allows a bug that is dangerous in pregnancy to be passed from man to woman to give her time to build up immunity.

Is Hydrogen The Future? This Car Goes 0 To 60 In 12 Seconds.

From Christian Science Monitor:

US Energy Secretary Steven Chu has said that hydrogen-fueled cars will not be pratical for a decade. But researchers at Hyundai-Kia Motors in South Korea say they're on course to make them in six years.

Yongin, South Korea - When the US government cut funding for hydrogen-fueled cars last May, Energy Secretary Steven Chu said such vehicles will not be practical for another decade or two.

Lim Tae-won thinks he can prove Secretary Chu wrong.

Dr. Lim runs the team at Hyundai-Kia Motors that is developing hydrogen fuel cell technology. And they are on course, he says, to mass produce hydrogen cars in six years.

Sleep Deprivation Cut Mental Function

From Future Pundit:

The brain downshifts to simpler ways of processing information when lacking sleep.

Westchester, Ill. —A study in the Nov.1 issue of the journal Sleep shows that sleep deprivation causes some people to shift from a more automatic, implicit process of information categorization (information-integration) to a more controlled, explicit process (rule-based). This use of rule-based strategies in a task in which information-integration strategies are optimal can lead to potentially devastating errors when quick and accurate categorization is fundamental to survival.

Flight test programs at Edwards Air Force Base and NASA’s Dryden Flight Research Center usually are off-limits to outsiders, but we got a peek at one of its coolest programs, the X-48B, when the Air Force recently threw open the gates for an open house.

The X-48B is the latest in a long line of experimental X-planes, and the joint venture between NASA and Boeing’s Phantom Works is unlike most that came before.

Why Three Buses Come At Once, And How To Avoid It

Bused up. Commuters can help keep transport moving (Image: Tony Kyriacou/Rex Features)

From New Scientist:

Anyone who has waited for a bus knows the routine: you wait far longer than you should, then three come along at once. The problem, called "platooning", plagues buses, trains and even elevators.

Now systems complexity researchers Carlos Gershenson and Luis Pineda of the National Autonomous University of Mexico have devised a mathematical model that shows how the problem might be prevented: transport managers need to get a little meaner about boarding times, and passengers should realise that jumping on the first train or bus that arrives won't always help them reach a destination faster.

In 3000 BC, it was 24 and stayed there almost until the industrial revolution. In 1850, it was 38. In 1909, it was 50. In 1959, it was 67. Current demographics indicate it’s only 78. The extra 26 years that Lancet predicts comes from anticipated future improvements in reducing death rates (morbidity).

A new book promises incontrovertible proof of the afterlife. That's cold comfort to those of us left behind.

On a spring day last year, three months after the death of my younger son, Max, I opened my front door and saw a butterfly resting on the steps—an Eastern tiger swallowtail, I later determined, a species native to the Northeast but not one I remembered seeing before in the middle of Brooklyn. The date stuck in my mind because, as it happens, it was also my birthday. The butterfly, with its otherworldly beauty and silence, is, of course, a common metaphor for the soul. Its emergence from entombment as a chrysalis may have inspired ideas about human resurrection.

Testing Cheap Wind Power

A continuously variable transmission could lead to cheaper wind power--if it is rugged enough.

Federal stimulus funds awarded to a wind-energy research consortium led by Illinois Institute of Technology will accelerate testing of small wind turbines that could point the way towards more efficient utility-scale machines. The eight-kilowatt turbines, the product of Cedar Park, TX-based Viryd Technologies, use a mechanical approach--continuously variable transmission (CVT) technology--to convert fluctuating wind speeds into the precise stream of alternating current required by power grids. If it can replace the pricey power electronics that regulate power in most turbines today, the same technology could cut the cost of wind-power generation at any scale.

5 Frightening (But True) Space Stories
