    Finding wonders in fat

    Who knew body fat held such hidden treasures? Scientists have found some serious loot in that bemoaned organ, including a vigorous population of flexible stem cells that can be coaxed into acting as new cartilage or tendons for damaged joints. Fat’s gems may also find uses in building new bone and repairing hearts, Susan Gaidos reports.

    One day such research might enable people to...

    FDA to test foods for controversial herbicide

    The U.S. government will test various foods for exposure to glyphosate, the active ingredient in several herbicides.

    Tests on foods including soybeans, corn, milk and eggs are set to begin this year, says Food and Drug Administration spokesperson Lauren Sucher. In 2014, the Government Accountability Office called on the FDA and the U.S. Department of Agriculture to strengthen their...

    Vaping linked to host of new health risks

    WASHINGTON — Many people have turned to electronic cigarettes in hopes of avoiding the heart and cancer risks associated with smoking conventional tobacco products. But vaping appears far from benign, a trio of toxicologists reported February 11 and 12 at the American Association for the Advancement of Science annual meeting.

    If used as a means to totally wean people off of tobacco...

    Whales are full of toxic chemicals

    European whales and dolphins may be at risk of extinction from the effects of polychlorinated biphenyls, or PCBs, a team of researchers recently reported in Scientific Reports. Concentrations of PCBs in killer whales and bottlenose and striped dolphins, they found, were high enough to cause health damage.

    PCBs have been banned in Europe, the United States and many other places for...

    PCB levels still high in Europe’s killer whales, smaller dolphins

    Decades after Europe banned toxic PCBs, the region’s killer whales and three smaller dolphin species still carry high levels of the pollutants.

    “They’re still at concentrations we really need to worry about,” said veterinary specialist Paul D. Jepson of the Zoological Society of London at a news conference January 12.  

    PCBs (polychlorinated biphenyls) were once industrial wonder...

    Year in review: BPA alternatives aren't benign

    A popular alternative to bisphenol A isn’t as benign as people had thought, at least not in lab animals.

    After a growing body of research identified hormone-mimicking effects from BPA — a compound found in some plastics, dental sealants and cash register receipts — consumers began reaching for BPA-free products. But there is now evidence that at least one of the chemical substitutes...
