The U.S. Food and Drug Administration is in the middle of a lengthy review of the chemical triclosan -- a product that's in countless consumer products like toothpaste and soap. There's a movement to try and get the product more stringently regulated in the United States -- or banned outright. And they might have just gotten a boost from Canada.
Humans have used fire for hundreds of thousands of years -- and used it in myriad ways. But a new study out this week, based on research in South Africa, shows that humans — or more precisely, their ancestors -- may have been using fire as much as a million years ago.
Genetic tests allow doctors to diagnose disease and patients to glimpse their medical future, but the knowledge of what's in your DNA doesn't always help. One English man discovered that the tests didn't change his life -- and in fact left him with a tough question.
New research on the air quality around natural gas wells provides additional evidence and controversy about the possible health effects from hydraulic fracturing or "fracking." In Colorado, scientists found that fracking wells emit potentially toxic hydrocarbons into the air.
President Obama's proposed budget for the 2013 fiscal year would cut funding for domestic fusion research in order to fund ITER, a multi-national fusion research project in France. That could mean lost jobs and a more limited market for physicists at research facilities like the MIT Plasma Science and Fusion Center.
James Cameron traveled some seven miles down into the ocean, as many miles below the Earth's surface as miles modern jetliners fly above the surface. He engineered a new deep sea submersible for the journey.
On Svalbard, in Norway, the farthest north inhabited place on Earth, scientists are at the center of research on climate change. It's also become a magnet for politicians, stars and even royalty who are looking to stake a claim as environmentalists.
A new report from Harvard University suggests that eating any red meat, even one serving, can increase your risk of dying. The research found that even a single serving increase your percentage risk by 13 percent — with processed meat, like bacon or hot dogs — increasing that risk 20 percent.
New archeological finds have led a Smithsonian Institute researcher to write a book detailing what he believes is the journey of the first Americans, from Europe to North America's east coast. This contradicts earlier evidence that the first Americans came from Asia.
Scientists at Columbia University have concluded that the Earth's oceans are becoming more acidic at an unprecedented rate — increasing more quickly than in the Earth's history, based on a review of oceanic fossils. It could bring disaster for marine life.
