Certain types of brain cancer cells, called cancer stem cells, help brain tumors to buffer themselves against radiation treatment by activating a "repair switch" that enables them to continue to grow unchecked, researchers at Duke University Medical Center have found.

Scientists at Case Western Reserve University School of Medicine and Albany Medical College, together with Rainforest Nutritionals, Inc. have demonstrated in a mini symposium held today at the 14th International Conference of the Inflammation Research Association (IRA) that a blend of natural botanical products called Reparagen have turned on the master repair gene, IGF-1, which is responsible for growing human cartilage and restores joint function while blocking joint destruction associated with inflammation. The IRA is the preeminent meeting for inflammation investigators.

Dr. Jayakrishna Ambati, of the University of Kentucky, and Dr. Balamurali Ambati, of the Medical College of Georgia, have jointly published a paper in the journal Nature detailing major research discoveries in corneal avascularity and angiogenesis.

Commercial fishing causes serious fluctuations in fish populations leaving them in danger of total collapse, says new research published today. These fluctuations mean current measures in place to control fish stocks may not be sufficient to ensure their sustainability.

A team of researchers has identified a new genetic mutation responsible for osteogenesis imperfecta (OI), a condition that makes bones much more likely to break, according to a study published today in the journal Cell.

Researchers at the University of Cambridge have discovered a new, more accurate, method of mapping how bacteria spread within the body, a breakthrough that could lead to more effective treatments and prevention of certain bacterial infections.

A fossil fish discovered in the West Australian Kimberley has been identified as the missing clue in vertebrate evolution, rewriting a century-old theory on how the first land animals evolved.

The deep-water vehicle VICTOR 6000. Not lava, but muds and methane are emitted from the Arctic deep-water mud volcano Haakon Mosby. When it reaches the atmosphere, methane is an aggressive greenhouse gas, 25-times more potent than carbon dioxide. Fortunately, some specialised microorganisms feed on methane and thereby reduce emissions of this greenhouse gas. For the first time, a German-French research team showed which methane consuming microorganisms thrive in the ice-cold Arctic deep-sea. In an article in the journal Nature, the scientists also describe which environmental parameters control their activity - with a surprising result: High flow velocities of mud volcano water in the seafloor reduce the efficiency of the natural gas filter by 60%.

A group of scientists led by the New York-based Wildlife Conservation Society (WCS) working in Mongolia's windswept Gobi Desert recently fitted high-tech GPS (Global Positioning System) collars on eight saiga antelope in an effort to help protect one of Asia's most bizarre-looking – and endangered – large mammals.
