The Environmental Appeals Board of the U.S. federal government has granted the DuPont corporation a three-year extension on its obligation to conduct a comprehensive assessment of a widely used chemical believed to expose consumers to the toxic substance perfluorooctanoic acid (PFOA).
A new drug halts the devastating progress of Alzheimer’s disease, say British scientists.
It is said to be more than twice as effective as current treatments.
A daily capsule of rember, as the drug is known, stops Alzheimer’s disease progressing by as much as 81 per cent, according to trial results.
A new DNA test for the virus that causes cervical cancer does so much better than current methods that some gynecologists hope it will eventually replace the Pap smear in wealthy countries and cruder tests in poor ones.
Not only could the new test for human papillomavirus, or HPV, save lives; scientists say that women over 30 could drop annual Pap smears and instead have the DNA test just once every 3, 5 or even 10 years, depending on which expert is asked.
Traces of a chemical used in rocket fuel were found in samples of powdered baby formula, and could exceed what's considered a safe dose for adults if mixed with water also contaminated with the ingredient, a government study has found.
The study by scientists at the U.S. Centers for Disease Control and Prevention looked for the chemical, perchlorate, in different brands of powdered baby formula. It was published last month, but the Environmental Working Group issued a press release Thursday drawing attention to it.
The chemical has turned up in several cities' drinking water supplies. It can occur naturally, but most perchlorate contamination has been tied to defense and aerospace sites.
