Amphibians, for years considered a leading indicator of environmental degradation, are not uniquely susceptible to pollution, according to a new meta-analysis.

Two-pronged protein attack could be source of SARS virulence

Researchers have uncovered what they believe could be the major factor contributing to the SARS virus' virulence: the pathogen's use of a single viral protein to weaken host cell defenses by launching a "two-pronged" attack on cellular protein-synthesis machinery.

Molecular architecture of Treponema pallidum, bacterium that causes syphilis

A team of scientists has used state-of-the-art technology to elucidate the molecular architecture of Treponema pallidum, the bacterium which causes syphilis. The previously unknown detailed structure of the bacteria can now be shown in three dimensions. This provides the first real image of the pathogen and reveals previously unknown features, which may help […]

New molecule implicated in diabetes-associated blindness

Scientists have demonstrated that the Wnt signaling pathway plays a role in diabetic retinopathy.

Climate change in Kuwait Bay: Higher temperatures having profound effects

Since 1985, seawater temperature in Kuwait Bay, northern Arabian Gulf, has increased on average 0.6 degrees Celsius per decade. This is about three times faster than the global average rate reported by the Intergovernmental Panel on Climate Change. Differences are due to regional and local effects. Increased temperatures are having profound effects on key ha […]

PTSD less common than depression and alcohol misuse amongst UK troops

Common mental disorders, such as depression and alcohol misuse, are the top psychological problems amongst UK troops post-deployment and not post traumatic stress disorder as is widely believed. A new study also finds that reservists remain at special risk of operational stress injury.

Black hole caught zapping galaxy into existence?

Which come first, the supermassive black holes that frantically devour matter or the enormous galaxies where they reside? A brand new scenario has emerged from a recent set of outstanding observations of a black hole without a home: black holes may be "building" their own host galaxy. This could be the long-sought missing link to understanding why […]

New stem cell technology provides rapid healing from complicated bone fractures

A novel technology involving use of stem cells has been applied to provide better and rapid healing for patients suffering from complicated bone fractures.

Immune cells that prevent development of asthma identified

Asthma is inhibited by regulatory macrophages, a cell population never previously described.

Quarter of a million children in England at risk of skin cancer from sunbeds
