Global warming five million years ago may have caused parts of Antarctica's large ice sheets to melt and sea levels to rise by approximately 20 meters, scientists report today in the journal Nature Geoscience.

Sex chromosome shocker: The 'female' X a key contributor to sperm production
Painstaking new analysis of the genetic sequence of the X chromosome--long perceived as the

Mental illness heightens early death risk in people with epilepsy
People with epilepsy are 11 times more likely to die prematurely than the general population, and the risk appears to be much higher for individuals with common co-existing psychiatric illnesses, especially depression and alcohol and drug use disorders, new research published in The Lancet suggests.

2 in 1 solution for low cost polymer LEDs and solar cells
Considerable improvement in device performance of polymer-based optoelectronic devices is reported today by researchers from Ulsan National Institute of Science and Technology, South Korea.

Study links mental illness to early death in people with epilepsy
People with epilepsy are 10 times more likely to die early, before their mid-fifties, compared with the general population, according to a 41 year study in Sweden published today in the Lancet and part-funded by the Wellcome Trust.

Loss of African woodland may impact on climate, study shows
A more strategic approach to managing trees across the continent could have a positive impact on the changing climate, researchers say.

Making big 'Schroedinger cats'
Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects.

A bad alliance: Rare immune cells promote food-induced allergic inflammation in the esophagus
Until recently, how EoE, a food allergy-associated disease, developed was unclear, but a new study shows that a type of rare immune cell and specific reactions to allergenic foods team up -- in a bad way.

Common stem cell in heart and lung development explains adaption for life on land
Biologists have known that the co-development of the cardiovascular and pulmonary systems is a recent evolutionary adaption to life outside of water.

Iberian lynx threatened by climate change
Climate change could drive the Iberian lynx -- the world's most threatened cat -- to extinction within 50 years, despite substantial ongoing conservation efforts, a new international study has found.

Failure to destroy toxic protein -- not buildup of protein itself -- contributes to Huntington's disease
Neurodegenerative diseases are often associated with the buildup of toxic proteins that lead to the death of neurons.

MS research could help repair damage affecting nerves
Multiple sclerosis treatments that repair damage to the brain could be developed thanks to new research.
