A Swedish research group, partly financed by NWO, has discovered a new mechanism for cell division in a microorganism found in extremely hot and acidic conditions. The results of the research offer insights into evolution, but also into the functioning of the human body. The research has been recently published in PNAS, the magazine of the American National Academy of Sciences. Thijs Ettema, member of the research group, received a Rubicon grant from NWO in 2006 to gain experience abroad.

Scientists at Penn State have shed light on some of the processes that regulate genes -- such as the processes that ensure that proteins are produced at the correct time, place, and amount in an organism -- and they also have shed light on the evolution of the DNA regions that regulate genes. The team focused on regulatory regions that, when bound to the protein GATA1, are thought to turn on genes that play an important role in the development of red blood cells. "Our findings could help others to develop drugs to treat people who suffer from sickle-cell anemia and other blood disorders," said Ross Hardison, the T. Ming Chu Professor of Biochemistry and Molecular Biology and the team's leader. The results will be published on 1 December 2008 in the journal Genome Research.

SARS – severe acute respiratory syndrome – alarmed the world five years ago as the first global pandemic of the 21st century. The coronavirus (SARS-CoV) that sickened more than 8,000 people – and killed nearly 800 of them – may have originated in bats, but the actual animal source is not known.

In human relationships, a certain "spark" often governs whether we prefer one person to another, and critical first impressions can occur within seconds. A team lead by Johns Hopkins researchers has found that cell-to-cell "friendships" operate in much the same way and that dysfunctional bonding is linked to the spread of cancer.

Enormous cave bears, Ursus spelaeus, that once inhabited a large swathe of Europe, from Spain to the Urals, died out 27,800 years ago, around 13 millennia earlier than was previously believed, scientists have reported.

A Mayo Clinic study shows a majority of stroke patients don't think they're having a stroke -- and as a result -- delay seeking treatment until their condition worsens. The findings appear in the current issue of Emergency Medicine Journal at http://emj.bmj.com/.
