Johns Hopkins researchers have added to the growing mound of evidence that many of the genetic bits and pieces that drive evolutionary changes do not confer any advantages or disadvantages to humans or other animals.
Color perception drifts away from neutrality during wakefulness and is restored during sleep, suggests a research abstract that will be presented Wednesday, June 9, 2010, in San Antonio, Texas, at SLEEP 2010, the 24th annual meeting of the Associated Professional Sleep Societies LLC.
A new study published in the Journal of the American Medical Association finds that students and school employees are being poisoned by pesticide use at schools and from drift off of neighboring farmlands. The public health advocacy organization Beyond Pesticides has called on Congress to respond by passing the School Environment Protection Act (SEPA).
An understanding of particle diffusion in the presence of constrictions is essential in fields as diverse as drug delivery, cellular biology, nanotechnology, materials engineering, and spread of pollutants in the soil. When a driving force is applied, displacement of particles occurs as well as diffusion. A paper in the Journal of Chemical Physics, which is published by the American Institute of Physics (AIP), quantifies the effects of periodic constrictions on drift and diffusion in systems experiencing a driving force.
The new IX3-ZDC2 module offers cutting-edge Olympus focal drift compensation technology, enabling accurate focus stability during long time-lapse experiments.
GE Healthcare announced today the successful completion of a vendor neutral Digital Imaging Repository that connects hospitals and medical centers throughout Southwestern Ontario, Canada, enabling the sharing of patient health data across the region. For the first time in Ontario's history, 26 hospital organizations in the Erie St. Clair and South West Local Health Integration Networks are able to share filmless diagnostic image exams between their facilities.
While positive attitudes toward gay men and lesbians have increased over recent decades, a new study led by researchers at IU's Center for Sexual Health Promotion shows attitudes toward bisexual men and women are relatively neutral, if not ambivalent.
Kaiser Permanente's experience while providing digital records to patients highlights the potential for miscommunications -- and sometimes needless alarm, The Huffington Post Investigative Fund reports. The health care company gave patients access to the same online lab reports that went to doctors and they included warning messages, such as a capital "H" to indicate above average results. That worried enough patients that the managed-care giant changed its format.
