How the environment could be damaging men's reproductive health

...moking mothers, and from 4.9% to 7.13% for mothers working in a potentially harmful environment. "Although this increased risk was not statistically significant, it suggests that environmental factors could be important," said Dr Jorgensen. [1] Exposure to persistent organochlorine pollutants associates wi...

Wisconsin researchers identify sleep gene

...conducted by Daniel Bushey, a post-doctoral fellow working with the Tononi team, revealed that their Shaker genes contained a single amino-acid mutation. Because of the mutation, a functional ion channel could not be formed on the cell membrane and potassium therefore could not flow through it. When the res...

Researchers devise way to mass-produce embryonic stem cells

...cells grown in the flask. The researchers are now working on ways to program embryonic stem cells so that they differentiate into specific types of cells. In preliminary work, Ouyang has created a network of neurons from undifferentiated embryonic stem cells. The next step is to use human embryonic stem ce...

Polymers with copper show promise for implanted sensors

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

...lenide," said Terry. "This is something we've been working to enhance in our lab. Getting inorganic selenium into gas form will allow it to just dissipate harmlessly into the atmosphere. No other form of remediation can do that." And what happens to the plants after they've soaked up their share of selenium...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

...ob." He says there "must be protective mechanisms working there, but we don't know what they are." The other members of the Weissman research team include Motomasa Tanaka and Peter Chien. The Weissman study was supported by Howard Hughes Medical Institute, The David and Lucile Packard Foundation, and the N...

WHO Warns Of Increased Risk Of Vector-borne Diseases In Tsunami-affected Areas

"WHO is working with national authorities and international teams in the region to conduct entomological surveys in affected districts with local staff being trained on the job. WHO is also making accessible insecticide-treated bed-nets, vector control supplies, and...

New Drugs For Bad Bugs: UF Approach Could Bolster Antibiotic Arsenal

... $1.6 billion to $1.8 billion. UF researchers are working on an approach known as PK/PD, which combines principles of pharmacokinetics, or an analysis of drug concentrations in the body, and pharmacodynamics, their effect on bacteria or how a drug kills bacteria. “In the past, blood samples were taken and ...

Computational Method Speeds Mapping of Cell Signaling Networks

...ntal methods. Multidisciplinary research teams are working on new approaches to make the process faster and easier. One such group, led by Garry Nolan of Stanford University and Douglas Lauffenburger of MIT has "opened the door for systematic mapping of signaling pathways," according to team member Dana Pe'...

New lab technique identifies high levels of pathogens in therapy pool

...ey were exposed to high levels of the pathogens by working consecutive, full days in the indoor pool environment. No patients became ill at the facility. The indoor pool water was kept at temperatures of 92 degrees to 94 degrees F and was treated with hydrogen peroxide rather than chlorine. The team found t...

Medical molecules designed to respond to visible light that can penetrate tissue

... chemistry and biology at Virginia Tech, have been working with Theralase Technologies Inc. to design molecular systems that use light that is in the therapeutic window. Starting with a complex with known DNA cleaving qualities, they changed the light absorber unit to one that responds to the red wavelength....

...off, Chairman and CEO of Pall Corporation. "We are working very closely with health authorities, starting with the nations hardest hit by vCJD, to help protect the safety of the blood supply and prevent the spread of this insidious disease." The new prion reduction filter will be evaluated by the United Kin...

Grizzlies set to invade high Arctic?

...says Dr. Jonathan Doupé, a postdoctoral researcher working with Dr. England. "We have bear safety courses when we go up there, and people would normally say you don't have to worry about grizzlies because it's really just polar bear country," he says. "But I think that's no longer the case." Dr. England no...
