Thawing permafrost in the Arctic could be emitting greenhouse gasses from previously unaccounted-for carbon stocks, fuelling global warming. That is the result of a study conducted by a team of geologists led by Professor ...

Deadly combination: New direct trigger for cell death discovered

Scientists led by Professor Ana J. Garcia-Saez at the CECAD Cluster of Excellence for Aging Research at the University of Cologne have shown that apoptosis, the programmed cell death, involves a direct physical interplay ...

Old protein, new function: tBID can directly trigger cell death

The protein tBID can trigger programmed cell death (apoptosis) by inducing damage in the energy suppliers of the cells, the mitochondria. Apoptosis is essential for maintaining tissue balance. In addition, apoptosis plays ...
