The small ice caps of Mont Blanc and the Dôme du Goûter are not melting, or at least, not yet. This is what CNRS researchers have announced in the Journal of Geophysical Research. At very high altitudes (above 4200 meters), the accumulation of snow and ice has varied very little since the beginning of the 20th century. But if summer temperatures increase by a few degrees during the 21st century, the melt could become more marked, and could affect the "permanent" ice fields.

When it comes to growing cells in a lab, technique matters. A new Brown University study shows that nerve cells grown in three-dimensional cultures use 1,766 genes differently compared to nerve cells grown in standard two-dimensional petri dishes.

The study, published in the May issue of Tissue Engineering, adds to a growing body of research showing that culture techniques can significantly affect cell growth and function.

The origin and movement of waves reaching up to 11 metres that devastated France's Reunion Island in the Indian Ocean on Saturday evening have been detected with ESA's Envisat satellite.

The waves that thrashed the southern port of Saint Pierre, leaving two fishermen missing, causing several piers to collapse and flooding several homes and businesses, originated south of Cape Town, South Africa, and travelled northeast for nearly 4000 km over a period of three days before slamming into Reunion Island.

If you have Mom's smile, Dad's eyes and Grandpa's laugh, you might wonder what other traits you picked up from the genealogic fabric of the ol' family tree.

Scientists at the Texas A&M University System Agricultural Research and Extension at Lubbock are studying the family tree of cotton for much the same reason.

A new study says that Pycnogenol natural pine bark extract from the French maritime pine tree helps prevent damage that high blood pressure causes to the heart. The study demonstrates Pycnogenol counteracts the "wearing out" of the heart, which may aid the five million Americans living with heart failure.

Previous studies have shown Pycnogenol supplementation to be associated with improved cardiovascular health, such as cholesterol reduction, blood pressure control and prevention of thrombosis.

"Hope is being given to patients with malignant and ultimately fatal spinal tumors where hope was never before available," said Dr. Isabelle Germano, Professor of Neurosurgery and Co-Director of The Radiosurgery Program at The Mount Sinai Medical Center. "All it takes is one thirty-minute out-patient treatment of pinpointed radiation and the tumor shrinks along with the pain from the cancer. Now cancer spreading to the spine doesn't mean a lifetime of pain or a wheelchair for a patient anymore."
