The "Blue Marble" image of Earth snapped by the crew of Apollo 17 in 1972 is one of the most famous photos ever taken. When it appeared, we all suddenly saw the world in a much different way.

In the years since, NASA has added other "Blue Marble" photos to its collection, and has used technology to enhance and sharpen the images.

Magic mushrooms are said to blow your mind, but the hallucinogenic chemical psilocybin, the active ingredient, actually reins in key parts of the brain, according to two new studies.

The memorably vivid emotional experiences reported by mushroom users may flourish because the parts of the brain suppressed by psilocybin usually keep our world view tidy and rational.

Two women losing their sight to progressive forms of blindness may have regained some vision while participating in an experiment testing a treatment made from human embryonic stem cells, researchers reported today.

The report marks the first time that scientists have produced direct evidence that human embryonic stem cells may have helped a patient. The cells had only previously been tested in the laboratory or in animals.

Let me take a second here.

Not very long, was it?

But a second tied up delegates to the UN's International Telecommunication Union, who postponed a decision this week on whether to abolish the extra second that's added to clocks every few years to compensate for the earth's natural doddering.

The earth slows down slightly as we spin through space. No one falls off, but earthquakes and tides routinely slow the earth by a fraction of a fraction of a second, which makes clocks minutely wrong. If not corrected, it could make a minute of difference a century.

Scientists watch comet plunge into the sun

Jan 19, 2012

For the first time ever, scientists have been able to watch a comet perform a deadly dive into the sun. Back in July, a Kreutz sungrazer known as C/2011 N3 passed so close to the sun that the icy body was vaporized.

By now we all know that distracted driving can kill you. But a new study suggests that distracted walking can be pretty deadly, too.

Smoking is banned at work. It’s banned in restaurants and bars. But most smokers can still head home and enjoy as many cigarettes as they’d like. That’s starting to change, when it comes to apartment buildings.

Don’t be surprised if you notice a few co-workers are out sick, or if a stomach bug seems to be hitting your family. Winter is peak time for sharing germs – and right now, at least, most of those are NOT the flu bug.

For Lisa Steinbrueck of Seattle, it seemed at first like food poisoning:

In many families, getting together over the holidays means someone inevitably gets bent out of shape for what someone else thinks is no good reason. New research by Washington State University and Oregon's Linfield College sheds light on knee-jerk reactions to innocent remarks.

Is Uncle Henry giving you the silent treatment, or is he just a man of few words? What did that friend you only see on New Year's Eve really mean when she said you lost weight?

Some say ignorance is bliss.  Others say ignorance is a drain on society.  But as contrary as it might sound, researchers have found there may actually be a place for the uninformed in group decision-making.

Paul Allen is bankrolling a dramatic new space-craft, which aims to launch satellites later this decade, and maybe people, too. The project uses an airplane made from two rebuilt Boeing 747’s. 

It looks a little like a flying catamaran. It will be the largest airplane ever built, with six jet engines. And hanging from the wing in the middle will be a rocket.

Stratolaunch Systems

Paul Allen’s new company, Stratolaunch Systems hopes to bring airport-like operations to the launch of commercial and government payloads and, eventually, human missions. Plans call for a first flight within five years, according to a company press release.

The air-launch-to-orbit system will mean lower costs, greater safety, and more flexibility and responsiveness than is possible today with ground-based systems, the company declares.

Losing your job often means losing your health insurance – and that’s reflected in the latest numbers of uninsured people in Washington. It’s approaching one million, or 14.5 percent of the population, according to the Office of the Insurance Commissioner.

A Washington State University researcher says new findings about the emotions of rats could lead to treatments for mental illness in humans. Jaak Panksepp writes in the latest issue of the journal, Science.

He was reacting to a new study showing that rats demonstrate empathy and altruism toward a fellow rat who was stuck in a trap.

If you’re an early riser, you may get to see a total eclipse of the moon on Saturday. The full moon will fall into a dark shadow in the hours just before dawn.

The northwestern U.S. gets a better view of this eclipse than the rest of the mainland states – that is, if you’re not fogged in.
