Researchers have uncovered a molecular mechanism that governs the formation of fears stemming from traumatic events. The work could lead to the first drug to treat the millions of adults who suffer each year from persistent, debilitating fears - including hundreds of soldiers returning from conflict in Iraq and Afghanistan. picked by AutumnLotus 1 year ago

Scientists have found new evidence that the Earth's natural feedback mechanism regulated carbon dioxide levels for hundreds of thousands of years.

But they say humans are now emitting CO2 so fast that the planet's natural balancing mechanism cannot keep up. picked by AutumnLotus 4 months ago

How can you possibly live when, every hour, the mechanism of the clock starts and takes you from your place? picked by wildminou 11 months ago

Taking a page from Nature herself, a team of researchers developed a method to enhance removal of carbon dioxide from the atmosphere and place it in the Earth's oceans for storage. picked by AutumnLotus 10 months ago

The delicate workings at the heart of a 2,000-year-old analogue computer known as the Antikythera Mechanism have been revealed by scientists. It computed and displayed the movement of the Sun, the Moon and possibly the planets around Earth, and predicted the dates of future eclipses. picked by teaya21 2 years ago

This is fascinating. I have long since pondered over how the torches work, the mechanics behind them, and the design.

This covers it all. picked by muppetmaker 3 months ago

The world's oldest calculator - a box of dials, gears and cogs created by the Ancient Greeks more than 2,000 years ago - could predict eclipses decades in advance, say researchers. picked by AutumnLotus 3 weeks ago

If you're one of those people who tends to bottle things up, only to explode ... don't hold it in so long. Studies show that bursts of anger here and there are good for the health, and can be an even more effective coping mechanism than becoming afraid, irritated or disgusted. picked by maxriter 1 year ago

Mouse Party is designed to provide a small glimpse into the chemical interactions at the synaptic level that cause the drug user to feel 'high'. When drugs enter the body they elicit very complex effects in many different regions of the brain. Every drug of abuse has its own unique molecular mechanism and this site illustrates them. picked by MasterPiece 7 months ago

Researchers are making another attempt at building a flying machine that uses the unique “cyclogyro” mechanism for generating a lifting force.... similar to the paddle wheels of a steamboat. Although cyclogyros were originally invented in the 1930s and a few companies have built different versions of the machine, there are no records of any successful flights. picked by snood 10 months ago

The Japanese have finally revealed a mystery for us. How does the small arrow on your computer monitor work when we move the mouse? Haven't you ever wondered how it works? Now, through the miracle of high technology, we can see how it is done. With the aid of a screen magnifying lens, the mechanism becomes apparent. picked by AutumnLotus 1 year ago

There seems to be therapeutic benefits in writing about personal experiences, thoughts and feelings. Besides serving as a stress-coping mechanism, expressive writing produces many physiological benefits. Research shows that it improves memory and sleep, boosts immune cell activity and reduces viral load in AIDS patients, and even speeds healing picked by 2manyusernames 3 months ago

Astronomers have found that a supernova discovered last year was caused by two colliding white dwarf stars. The white dwarfs were siblings orbiting each other. They slowly spiraled inward until they merged, touching off a titanic explosion. CfA observations show the strongest evidence yet of what was, until now, a purely theoretical mechanism for creating a supernova. picked by AutumnLotus 10 months ago

Researchers from University of Colorado at Boulder studied the mechanism of pushing aside memories on negative emotions to develop a therapy helping people suffering from post-traumatic stress, depression, anxiety and various fears. picked by maxriter 1 year ago

Humans can see into the future, says a cognitive scientist. It's nothing like the alleged predictive powers of Nostradamus, but we do get a glimpse of events one-tenth of a second before they occur.

And the mechanism behind that can also explain why we are tricked by optical illusions. picked by AutumnLotus 3 months ago

The launch of two liberal Muslim groups is indicative of a corrective mechanism taking place among British Muslims. An effort to show that not all or even most Muslims are fanatics. They want to show a different way and are not afraid to speak out even when threatened.Even formerly violent Muslims wish to seek a peaceful co-existentence. picked by 2manyusernames 4 months ago

A hijack-proof piloting system for airliners is being developed. The mechanism is designed to make it impossible to crash the aircraft into air or land targets - and enable the plane to be flown by remote control from the ground. picked by 2manyusernames 1 year ago

Two professors propose an inte-grated and dramatic mechanism for the formation of kimberlites, the enigmatic structures bearing most of the world’s diamonds. Their theory explains many puzzling features of the formations and also suggests that the location of kimberlites is not related to near-surface geology. picked by AutumnLotus 1 year ago
