Over the coming weeks an international team, led by Professor Ulrich Heber of the University of Erlangen-Nuernberg, Germany, will use over fifteen different telescopes around the world to make over one hundred nights of observations of just one star to learn about its internal structure.

The constellation of the “Serpent” contains a variable star, called V338 Ser, which vibrates with several periods of about ten minutes. It is a very old and nearly burnt out star which has lost most of its o

Scientists at UCL have developed a drug to treat a serious medical condition linked to Alzheimer`s disease and type 2 diabetes. The research, supported by the Medical Research Council (MRC) and reported in NATURE, is the culmination of 25 years of basic and clinical research and the UCL scientists hope that it may be the key to the treatment of other serious diseases.

Crucially, Professor Mark Pepys and his team have managed for the first time to remove from the human body a naturally occurr

Research funded by the European Space Agency into ways of feeding future astronauts on missions to Mars is about to find a very down-to-earth application – how to dispose of the sewage sludge left over after wastewater treatment.

The MELISSA (Micro-Ecological Life Support Alternative) project, which ESA is funding in companies and research institutes throughout Europe, is developing a system of recycling as much of the waste as possible produced by astronauts on long-duration space missions

High-energy bubbles scour municipal water filters.

Sound waves could provide a greener way to make tap water taste better.

Ultrasound can make bubbles in water that could clean ceramic filters quickly and cheaply, say Linda Weavers and colleagues of Ohio State University, Columbus 1 . When the bubbles burst, they release energy that makes tiny, but fiercely powerful, jets of water that scour the filter’s surface and flush away debris.

Most municipa

A dose of heavy housework will meet new recommended targets for daily physical activity levels, but there is no evidence that it is good for health, finds research in the Journal of Epidemiology and Community Health. Brisk walking is a much healthier option, shows the study.

Over the past 10 years, there has been shift in policy from recommending three bouts of vigorous exercise a week to more moderate activity that fits into a daily routine. This includes housework, gardening, and DIY, on t

About 30 years ago, astronomers realised that the Sun resonates like a giant musical instrument with well-defined periods (frequencies). It forms a sort of large, spherical organ pipe. The energy that excites these sound waves comes from the turbulent region just below the Sun`s visible surface.

Observations of the solar sound waves (known as “helioseismology”) have resulted in enormous progress in the exploration of the interior of the Sun, otherwise hidden from view. As is the case on Eart
