NASA sees Hurricane Sandy as the "Bride of Frankenstorm" approaching the US East Coast

NASA's TRMM satellite revealed Hurricane Sandy's heavy rainfall and the storm is expected to couple with a powerful cold front and Arctic air to bring that heavy rainfall to the Mid-Atlantic and northeastern US. Some forecasters are calling this combination of weather factors "Frankenstorm" because of the close proximity to Halloween. However, because Sandy is a woman's name, the storm could be...

Researchers decipher the mecanism of membrane fission

Researchers at the University of Geneva, in collaboration with the Institut Curie, shed light on the mechanism of the fission of cell membranes. They used an in vitro analysis of the functioning of dynamin, a protein involved in this mechanism.

Results of the STEMI-RADIAL trial presented at TCT 2012

A study found several benefits in using the radial artery in the arm as the entry point for angioplasty or percutaneous coronary intervention compared to the femoral artery in the leg. Results of the STEMI-RADIAL trial were presented today at the 24th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium. Sponsored by the Cardiovascular Research Foundation, TCT is the world's...

Results of the XIMA trial presented at TCT 2012

Rarely tested in patients over the age of 80, a study found that drug-eluting stents exhibited some benefits over bare-metal stents, though both types of stents demonstrated a clinical benefit. Results of the XIMA trial were presented today at the 24th annual Transcatheter Cardiovascular Therapeutics scientific symposium. Sponsored by the Cardiovascular Research Foundation, TCT is the world's...

Salk study finds diabetes raises levels of proteins linked to Alzheimer's features

Growing evidence suggests that there may be a link between diabetes and Alzheimer's disease, but the physiological mechanisms by which diabetes impacts brain function and cognition are not fully understood. In a new study published in Aging Cell, researchers at the Salk Institute for Biological Studies show, for the first time, that diabetes enhances the development of aging features that may...

Scientists step up hunt for bacterial genes tied to Lyme disease

Lyme disease is a bacterial illness that affects tens of thousands. It can lead to abnormalities in the nervous system, heart and joints. New research into the bacterium's genetic makeup could advance the diagnosis, treatment or prevention of the disease. A preclinical study by scientists at the University of Texas Health Science Center at Houston appears in the journal PLOS ONE.

Solving stem cell mysteries

The ability of embryonic stem cells to differentiate into different types of cells with different functions is regulated and maintained by a complex series of chemical interactions, which are not well understood. Learning more about this process could prove useful for stem cell-based therapies down the road. New research from a team led by Carnegie's Yixian Zheng zeroes in on the process by which...

Watching the cogwheels of the biological clock in living cells

Most physiological functions in mammals are controlled by a daily internal time-keeping system, termed the circadian clock. The transcription of many genes producing detoxifying enzymes is regulated by DBP, a protein that is itself expressed in a highly rhythmic fashion. The group of Ueli Schibler, professor at the University of Geneva, Switzerland, deciphered the molecular basis of how the...

Cesium levels in fish off Fukushima not dropping

Radioactive cesium levels in most kinds of fish caught off the coast of Fukushima haven't declined in the year following Japan's nuclear disaster, a signal that the seafloor or leakage from the damaged reactors must be continuing to contaminate the waters — possibly threatening fisheries for decades, a researcher says.
