The Department of Geology and Environmental Science at the University of Akron will host a regional earth science conference next Thursday and Friday, 20-21 April.

New mechanism for essential genome-wide gene silencing identified
Estimates are that only about 10 percent of the roughly 25,000 genes in the human genome are activated, or

Lizard 'third eye' sheds light on evolution of color vision
Lizards have given Johns Hopkins researchers a tantalizing clue to the evolutionary origins of light-sensing cells in people and other species.

Graphite-based circuitry may be foundation for devices that handle electrons as waves
A study of how electrons behave in circuitry made from ultrathin layers of graphite - known as graphene - suggests the material could provide the foundation for a new generation of nanometer scale devices that manipulate electrons as waves - much like photonic systems control light waves.

Bioactive cement scaffold may improve bone grafts
A new technology for implants that may improve construction or repair of bones in the face, skull and jaw, has been developed by researchers from the American Dental Association Foundation (ADAF) and the National Institute of Standards and Technology (NIST).

Tips from the journals of the American Society for Microbiology
The current issue includes the following press releases: Ulcer Drug Inhibits Gum Disease in Rabbits; Artificial Illumination Using White or Green Light; May Prevent Biofilm Formation on Artwork; and Archaea Identified As Possible Human Pathogen.

Conference calls for global approach to risk management in medicines, food, environment
Leaders from industry and national and international regulatory bodies will share perspectives on the shifting landscape of risk management for pharmaceuticals, medical devices, healthcare networks, food production, environmental control, and transportation at

Understanding cell death may bring new life to kidney treatment
Finding how two proteins conspire to get kidney cells to self-destruct when oxygen supplies are low may one day improve dismal mortality rates for ischemic renal failure, researchers say.

NFL team physicians to host conference on football injury prevention and conditioning
Join us in Hollywood, FL, where team physicians and head athletic trainers representing 17 NFL teams and 5 NCAA Div.

Temperatures, not hotels, likely alter Niagara Falls' mist
What's up with the mist? When the Niagara Parks Commission posed that question back in 2004, the concern was that high-rise hotels on the Canadian side of Niagara Falls were contributing to the creation of more mist, obscuring the very view that millions of tourists flock there every year to see.

Personalized medicine, future of pharmaceuticals explored in UH lecture
With the potential for reducing or eliminating side effects and improving a patient's recovery, personalized medicine - tailor-made medications based on an individual's genetic information to develop drugs customized for an individual patient's particular condition and side-effects profile - is revolutionizing the field of drug discovery and development.

New maps provide clues to the historic 2005 red tide outbreak in New England
Scientists at the Woods Hole Oceanographic Institution (WHOI) have completed two extensive survey and mapping efforts to better understand why the 2005 New England red tide was so severe and to suggest what might lie ahead.

Parts of the Caribbean and Central America are likely to have less summer rain
Parts of the Caribbean and Central America are likely to experience a significant summer drying trend by the middle of this century, UCLA atmospheric scientists report in the Proceedings of the National Academy of Sciences, based on an analysis of 10 global climate computer simulations.

New gene reduces retinal degeneration in fruit flies
Johns Hopkins researchers have discovered a gene in fruit flies that helps certain specialized neurons respond more quickly to bright light.

Patients with severe sleep-disordered breathing have high odds of abnormal heart rhythms
Patients with severe sleep-disordered breathing are two to four times more likely to experience complex, abnormal heart rhythms while sleeping than individuals without the problem, according to the Sleep Heart Health Study.

Endurance walking test distances improved significantly for COPD patients
Breathing a special gas mixture may significantly improve the exercise performance of individuals with severe chronic obstructive pulmonary disease (COPD).

Microfluidic device tests fluid compatibility
To help industrial engineers improve their ability to systematically test new product formulations, researchers at the National Institute of Standards and Technology (NIST) have developed a microfluidic instrument that quickly measures

Other people influence us and we don't even know it
