Scientists at the Max Planck Institute of Metals Research in Stuttgart have discovered a new mechanism with which it is possible to use weak magnetic fields to reverse tiny magnetic structures, called vortex cores, quickly and with no losses. Up until now, very strong magnetic fields have been necessary to accomplish this, requiring highly complex technology. The new method might open up new possibilities for magnetic data storage.
Hematopoietic stem cell transplant (HSCT) recipients face a significant long-term risk for developing a second cancer, particularly if they were older at the time of transplant or received stem cells from a female donor, according to a new study.
Robert Richardson II, an HIV positive man accused of knowingly exposing three women to the virus has been sentenced to nearly three years in prison. A Kansas judge Judge Stephen Six imposed the sentence after a jury found him guilty.
More than a week after a violent rainstorm forced murky water into Greater Vancouver’s reservoirs, the region’s drinking water has been declared free of contamination, public health officials said.
New research uses an electroencephalogram (EEG) to look for a connection between brain activity thought to reflect trait-like differences in emotionality and alcoholism. Findings show an asymmetry of activity in the left and right frontal areas of the brain.
People with poor memory may face a higher risk of cardiovascular or heart-related diseases like heart attack or myocardial infarction, MI, revealed by researchers from the Edinburgh University.
King Pharmaceuticals, Inc. (NYSE: KG) and Depomed, Inc. (NASDAQ: DEPO) today announced the launch of a new program that will provide support for patients with diabetes who are receiving treatment with Glumetza (metformin hydrochloride extended-release tablets), a new once-daily extended-release metformin formulation that features AcuForm drug-delivery technology.
Highly concentrated botulinum preparation for cosmetic injections can result in severe illness. An examination of 4 cases of botulism following cosmetic injections to the face indicates that the adults received a highly concentrated, unlicensed preparation that resulted in toxin levels up to 40 times the estimated human lethal dose, according to a report in the November 22/29 issue of JAMA.
An international team led by scientists from the United States and New Zealand have observed, for the first time, the bizarre deep-sea communities living around methane seeps off New Zealand’s east coast. This is the first time cold seeps have been viewed and sampled in the southwest Pacific. Cold seeps are areas of the seafloor where methane gas or hydrogen sulphide escapes from large stores deep below.
The largest superconducting magnet ever built has successfully been powered up to its operating conditions at the first attempt. Called the Barrel Toroid because of its shape, this magnet is a vital part of ATLAS, one of the major particle detectors being prepared to take data at CERN’s Large Hadron Collider (LHC), the new particle accelerator scheduled to turn on in November 2007.
