Planetary geologists at Brown University have found a gully fan system on Mars that formed about 1.25 million years ago. The fan offers compelling evidence that it was formed by melt water that originated in nearby snow and ice deposits and may stand as the most recent period when water flowed on the planet.

Gullies are known to be young surface features on Mars. But scientists studying the planet have struggled with locating gullies they can conclusively date. In a paper that appears on the cover of the March issue of Geology, the Brown geologists were able to date the gully system and hypothesize what water was doing there.

Want your kids to eat more carrots?   Call them 'X-ray carrots', says a new Cornell University study which shows that giving vegetables catchy new names – like X-Ray Vision Carrots and Tomato Bursts – left preschoolers asking for more.

When 186 four-year olds were given carrots called "X-ray Vision Carrots" ate nearly twice as much as they did on the lunch days when they were simply labeled as "carrots." The Robert Wood Johnson-funded study also showed the influence of these names might persist. Children continued to eat about 50% more carrots even on the days when they were no longer labeled. The new findings were presented on Monday at the annual meeting of the School Nutrition Association in Washington DC. 

Young men who have served in the British Armed Forces are up to three times more likely to take their own lives than their civilian counterparts, research published tomorrow (March 3) has found.

Researchers at The University of Manchester's Centre for Suicide Prevention linked UK military discharge data between 1996 and 2005 with details of suicides collected by the National Confidential Inquiry into Suicides and Homicides.

Sometimes known as "nature's origami", the way that proteins fold is vital to ensuring they function correctly. But researchers at the University of Leeds have discovered this is a 'hit and miss' process, with proteins potentially folding wrongly many times before they form the correct structure for their intended purpose. 

The body's proteins carry out numerous functions and play a crucial role in the growth, repair and workings of cells. Sheena Radford, Professor of Structural Molecular Biology at the University of Leeds, says: "There's a fine balance between a protein folding into the correct shape so that it can carry out its job efficiently and it folding incorrectly, which can lead to disease. Just one wrong step can tip that balance."

Women can take pride that they are more efficient than men in many ways, including one that is not so great; storing fat.

It's a paradox women have discussed for generations – their apparent ability to store fat more efficiently than men, despite eating proportionally fewer calories.   While it has long been suspected that female sex hormones are responsible, a University of New South Wales (UNSW) research review has for the first time drawn a link between one hormone – estrogen – and its impact on fat storage for childbearing.

LONDON, March 2 /PRNewswire/ -- The Myelodysplastic Syndromes (MDS) Foundation is pleased to support the licensed use of VIDAZA in the United Kingdom and Ireland to treat a subset of patients with intermediate-2 and higher-risk MDS, chronic myelomonocytic leukaemia (CMML) and acute myeloid leukaemia (AML with 20-30% blasts).

LONDON, March 2 /PRNewswire/ -- The granting by EMEA of full marketing authorisation for Celgene's VIDAZA will bring new hope to MDS patients, particularly those with high risk forms of these diseases that historically have been associated with a bleak outlook.

Patients who are ineligible for stem cell transplant therapy are often subjected to the discomfort, inconvenience and complications that can be associated with essential, regular blood transfusions, a life saving procedure which remains the mainstay of MDS treatment.
