Break-up Of Antarctic Ice May Expose Marine Life To More Sunlight And Alter Food Chain

Despite the icy cold and darkness, beneath the frozen surface of the sea in Antarctica thrives a rich and complex array of plants and animals. But what will happen to all those creatures if global warming reduces the ice-cover, as is predicted for coming decades?

UNSW marine ecologists Dr Emma Johnston and Graeme Clark have been working with the Australian Antarctic Division to survey marine communities along the striking coast of Wilkes Land, east Antarctica.

Caffeine limits blood flow - coffee may impair peak heart function

In healthy volunteers, the equivalent of two cups of coffee reduced the body's ability to boost blood flow to the heart muscle in response to exercise, and the effect was stronger when the participants were in a chamber simulating high altitude, according to a new study in the Jan. 17, 2006, issue of the Journal of the American College of Cardiology.

The First Molecular Keypad Lock

How can defense or intelligence agencies safeguard the security of top-secret data protected by a computation device the size of a single molecule?

With cryptography approaching that sobering new era, scientists in Israel are reporting development of what they term the first molecular system capable of processing password entries. Abraham Shanzer and colleagues describe their "molecular keypad lock" in the Jan. 17 issue of the weekly Journal of the American Chemical Society.

Study gives us a new perspective on the powerful

Walking a mile in another person's shoes may be the best way to understand the emotions, perceptions, and motivations of an individual; however, in a recent study appearing in the December 2006 issue of Psychological Science, it is reported that those in power are often unable to take such a journey.

Mechanism Of Hallucinogens' Effects Discovered

The brain mechanism underlying the mind-bending effects of hallucinogens such as LSD, mescaline, and psilocybin has been discovered by neuroscientists. They said their discoveries not only shed light on the longtime mystery of how hallucinogens work, but that the findings also offer a pathway to understanding the function of drugs used to treat neuropsychiatric disorders, which are now being used largely without an understanding of their fundamental mechanism.
