If you're a mouse and you like fatty foods, we have good news for you.   Researchers at the University of California, Berkeley have identified a new enzyme that helps control the breakdown of fat and the mice that have had this enzyme disabled remained lean despite eating a high-fat diet and losing a hormone that suppresses appetite.

The enzyme in the spotlight, adipose-specific phospholipase A2 (AdPLA), is found in abundance only in fat tissue. AdPLA sets off a chain of events that increases levels of a signaling molecule called prostaglandin E2 (PGE2), which suppresses the breakdown of fat. Mice that have no AdPLA have lower PGE2 levels and a higher rate of fat metabolism.

How did life begin?   A pair of Scripps Research Institute scientists say they have taken a significant step toward answering that question because they have synthesized RNA enzymes that can replicate themselves without the help of any proteins or other cellular components - and the process proceeds indefinitely. 

Is gardening one of your interests? If so and you live in central or northern Europe the 'killer slug' is probably one of your personal enemies. The slug, which attacks your herbs and vegetables relentlessly, seems immune to control measures.

The killer slug, suffocating lobster, globe trotting televisions and dangerous air particles are just some of the topics featured in EEA Signals 2009, a new annual publication from the European Environment Agency, launched today in Prague by Czech Environment Minister Bursik and Executive Director of the EEA, Professor Jacqueline McGlade.

The EEA, in partnership with its network of 32 member countries, monitors the environment across Europe.

No one can draw a connection between meteorite impacts and massive volcanic activity but the one certain instance where it has been confirmed, at the Cretaceous-Tertiary boundary, was the catastrophic event thought to be responsible for the extinction of the dinosaurs 65 million years ago. 

Crucial breakthroughs in the treatment of many common diseases such as diabetes and Parkinson's could be achieved by harnessing systems biology, according to scientists from across Europe.   In a Science Policy Briefing released today by the European Science Foundation, they provide a detailed strategy for the application of systems biology to medical research over the coming years.

London South Bank University designer Sarah Elenany says there is a lack of fashionable clothing that meets Islamic cultural requirements so she has launched an eponymous clothing line that unites urban chic with Islamic culture.   Elenany, 24, calls her new label ‘Elenany’ and says she has drawn inspiration from Islamic art and combined it with contemporary styling for a truly innovative brand.
