A Bose-Einstein condensate, a form of matter heretofore only observed in atoms chilled to less than a millionth of a degree above absolute zero, may now have been observed at temperatures in excess of one degree Kelvin in excitons, the bound pairs of electrons and holes that enable semiconductors to function as electronic devices.

Undergoing anaesthesia may be more like falling asleep than we once thought, according to new research from Imperial College London and Harvard Medical School, USA.

Researchers report today in the journal Nature Neuroscience how two of the most widely used anaesthetics, pentobarbital and propofol induce sleep by mimicking the natural process of falling into a deep sleep.

Using behavioural studies and molecular imaging techniques in rats, the team of basic scientists and clinicians

New research sheds light on gender differences, running and racing animals

Was Lassie only the second fastest collie in the valley? Was Roy Rogers’s horse Trigger faster than Dale Evans’s filly, Buttermilk? Men are readily acknowledged as faster runners than women. Can the same assumption be made about gender in horses and dogs?

Background

It’s not too hard to see why that assumption might be made. Sir Roger Bannister ran the first sub-four minute mile in 19

In a powerful demonstration of how animal research can help humans, a pair of scientific teams is reporting the discovery of defects in a deafness gene in mice that led to the identification of similar genetic defects in people with hearing loss.

The findings, published in two new papers, may eventually lead to a screening test and therapy for families affected by one type of inherited hearing loss.

The discoveries also bring scientists closer to understanding the intricate choreo

Testing pregnant women for gestational diabetes at 16-weeks of pregnancy is a more efficient way to screen for the disease than the current method of screening women during their third trimester, said Gerard Nahum, M.D., an associate clinical professor at Duke University Medical Center’s department of obstetrics and gynecology.

The earlier tests, Nahum said, allow women at highest risk for gestational diabetes to be identified and treated earlier, possibly heading off complications in both

Satellites show overall increases in antarctic sea ice coverWhile recent studies have shown that on the whole Arctic sea ice has decreased since the late 1970s, satellite records of sea ice around Antarctica reveal an overall increase in the southern hemisphere ice over the same period. Continued decreases or increases could have substantial impacts on polar climates, because sea ice spreads over a vast area, reflects solar radiation away from the Earth’s surface, and insulates the oceans from t
