Telephone Press Conference: NTP Draft Conclusions for Radiofrequency Radiation Studies in Rats and Mice

Thu, 1 Feb 2018 13:00:00 -0500

What: The National Toxicology Program (NTP) will hold a telephone press conference to summarize and answer questions about draft reports on the health effects of radiofrequency radiation exposure in rats and mice. The studies used radiofrequency radiation exposure levels equal to and higher than the highest level permitted for cell phone emissions today. Two draft reports – one on rat studie...

Roadmap to Guide Progress Toward Replacing Animal Use in Toxicity Testing

Tue, 30 Jan 2018 09:00:00 -0500

Sixteen federal agencies partnered to develop a strategic roadmap that offers a new framework for the safety testing of drugs and chemicals, which aims to provide more human relevant toxicology data while reducing the use of animals. The roadmap was published Jan. 30 by the National Toxicology Program (NTP), a federal interagency program headquartered at the National Institute of Environmental Hea...

New Tool Visualizes Employment Trends in Biomedical Science

Wed, 24 Jan 2018 00:00:00 -0500

Scientists looking for jobs after completing their training may soon have a new tool that helps them evaluate various career paths. The new tool uses a method that was developed by scientists at the National Institute of Environmental Health Sciences (NIEHS), part of NIH. The method differs from others in that it separates employment trends in biomedical science by sector, type, and job specifics....

Brian Berridge Tapped to Manage National Toxicology Program

Fri, 12 Jan 2018 11:00:00 -0500

The National Toxicology Program (NTP) has named Brian Berridge, D.V.M., Ph.D., as its new Associate Director. Berridge, formerly of GlaxoSmithKline, will oversee day-to-day operations as NTP coordinates toxicology research and testing across nine different federal agencies, including the National Institutes of Health, the U.S. Food and Drug Administration, and the Centers for Disease Control and P...

Defending Against Environmental Stressors May Shorten Lifespan

Wed, 20 Dec 2017 14:30:00 -0500

Using fruit flies, NIH researchers provide molecular basis for theory of aging A shorter life may be the price an organism pays for coping with the natural assaults of daily living, according to researchers at the National Institutes of Health and their colleagues in Japan. The scientists used fruit flies to examine the relationship between lifespan and signaling proteins that defend the body agai...

Allergens Widespread in Largest Study of U.S. Homes

Thu, 30 Nov 2017 09:00:00 -0500

Allergens are widespread, but highly variable in U.S. homes, according to the nation’s largest indoor allergen study to date. Researchers from the National Institutes of Health report that over 90 percent of homes had three or more detectable allergens, and 73 percent of homes had at least one allergen at elevated levels. The findings were published November 30 in the Journal of Allergy and ...

DNA Damage Caused by Cancer Treatment Reversed by ZATT Protein

Fri, 6 Oct 2017 00:00:00 -0400

An international team led by scientists at the National Institutes of Health is the first to discover a new way that cells fix an important and dangerous type of DNA damage known as a DNA-protein crosslink (DPC). The researchers found that a protein named ZATT can eliminate DPCs with the help of another protein, TDP2. Since DPCs form when individuals receive some types of cancer treatments, unders...

Gulf Spill Oil Dispersants Associated with Health Symptoms in Cleanup Workers

Tue, 19 Sep 2017 00:00:00 -0400

Workers who were likely exposed to dispersants while cleaning up the 2010 Deepwater Horizon oil spill experienced a range of health symptoms including cough and wheeze, and skin and eye irritation, according to scientists at the National Institutes of Health (NIH). The study appeared online Sept. 15 in Environmental Health Perspectives and is the first research to examine dispersant-related health...

Female Mouse Embryos Actively Remove Male Reproductive Systems

Thu, 17 Aug 2017 14:00:00 -0400

NIH researchers reveal novel insights into how sex-specific reproductive systems arise A protein called COUP-TFII determines whether a mouse embryo develops a male reproductive tract, according to researchers at the National Institutes of Health and their colleagues at Baylor College of Medicine, Houston. The discovery, which appeared August 18 in the journal Science, changes the long-standing bel...
