In his latest research, published in WIREs Climate Change, historian Matthias Dorries examines the cultural significance of fear and how it became a central presence in current debates over climate change.

The forming of folded structures

What do the convolutions of the brain, the emergence of wrinkles, the formation of mountain chains, and fingerprints have in common? All these structures, albeit very different, result from the same process: the compression of a 'rigid membrane'. A French-Belgian team involving the Statistical Physics Laboratory and the Interfaces and Complex Fluids Laboratory at the University of Mons in Belgium...

Promising target for new pancreatic cancer treatments discovered

For almost three decades, scientists and physicians have known that a gene called the KRAS oncogene is mutated in virtually all pancreatic cancers, making it an important target for scientists looking for a way to stop the growth of pancreatic cancer tumors. Medical researchers have now narrowed the focus of this scientific quest to a protein called...

Extreme form of pregnancy-related morning sickness could be genetic

Research that traced both the maternal and paternal family histories of women with hyperemesis gravidarum -- an extreme form of pregnancy-related morning sickness that hospitalizes 60,000 pregnant women each year -- suggests not only that the condition could be genetic but that women with sisters who had HG could have a more than 17-fold risk of experiencing the debilitating condition...

Small protein changes may make big difference in natural HIV control

Tiny variants in a protein that alerts the immune system to the presence of infection may underlie the rare ability of some individuals to control HIV infection without the need for medications. An international research team has found that differences in five amino acids in a protein called HLA-B are associated with whether or not HIV-infected individuals can control viral levels with their...

Study: Obesity Is Contagious Among Friends

The more obese friends you have, the more likely you are to become obese, a new study suggests. This confirms previous research that gaining weight may be socially contagious. The research also shows that if nothing changes significantly in the environment and culture in the USA, about 42 percent of adults will be obese in about 40 years and then the obesity rate will level off. About a...

Study Finds Location-Based Services Growing Slowly

Location-based services may be poised for growth, but only a small percentage of mobile users are taking advantage of them. That's the big takeaway from a new study released Thursday by the Pew Internet and American Life Project. The study found that only four percent of all Internet users utilize such location-based services as Foursquare and Gowalla, which allow them to share their current...
