Young women undergoing chemotherapy for certain types of breast cancer may be able to preserve their fertility by adding the drug goserelin to their treatment, researchers said Friday. The cancer drug also appeared to improve survival, according to…
Plutonium found in Colorado soil at five times higher level than acceptable radioactive level
Why is there plutonium in the soil of a national wildlife refuge that is five times higher than the rate that demands a "clean up?" It's a question Colorado state health officials are examining Tuesday after their soil sample readings showed 264 picocuries-per-gram found in Rocky Flats National Wildlife Refuge.
The Denver Post reported the findings of the radioactive substance, but toxicologists at the Colorado Department of Public Health and Environment said they don't believe "there is an immediate public health threat."
New planet discovered in orbit of young Milky Way star
A second planet has been discovered circling Beta Pictoris, a fledgling star in our own galaxy offering astronomers a rare glimpse of a planetary system in the making, according to a study published Monday.
"We talking about a giant planet about 3,000 times more massive than Earth, situated 2.7 times further from its star than the Earth is from the Sun," said Anne-Marie Lagrange, an astronomer at France's National Centre for Scientific Research and lead author of a study in Nature Astronomy.
The new planet, b Pictoris c, completes its orbit roughly every 1,200 days. Like its big sister b Pictoris b, discovered by Lagrange and her team in 2009, it is a gassy giant.
Controversial study links fluoride in water to lower IQ
A study published Monday links exposure to fluoridated tap water during pregnancy to lower IQ scores in infants, but several outside experts expressed concern over its methodology and questioned its findings.
Fluoride has been added to community water supplies in industrial countries to prevent tooth decay since the 1950s.
Very high levels of the mineral have been found to be toxic to the brain, though the concentrations seen in fluoridated tap water are generally deemed safe.
"We realized that there were major questions about the safety of fluoride, especially for pregnant women and young children," Christine Till at Canada's York University, senior author of the paper published in JAMA Pediatrics, told AFP.
