A 2013 study by Pérez et al. reported a very high accumulation of the industrial chemical perfluorobutanoic acid (PFBA) in human lungs and kidneys. The German Federal Institute for Risk Assessment (BfR) checked these results using a more precise quantification method. The result: Only one sample contained a quantifiable PFBA value of 0.17 nanograms (ng) […]

The Real Difference Between Mineral Sunscreen And Chemical Sunscreen
Whether you’re spending the day at the beach or just walking to a local coffee shop, it’s important to wear sunscreen to protect your skin from harmful rays. Ultraviolet (UV) light from the sun can cause wrinkles, liver spots, and even skin cancer. According to the World Cancer Research Fund, melanoma is the 19th most […]
Children and young people have too many long-lasting chemicals in the blood
Children and young people in Germany have many long-lasting chemicals in the blood. The President of the Federal Environment Agency (UBA), Dirk Messner, warned on Monday in Dessau, the damage caused by them are often still unexplored. Specifically, it is the so-called per – and polyfluorinated chemicals, short-PFAS. They are used for example for the […]
Shifts in chemical rhythms may cause eating behaviors that lead to obesity
Obesity is a common health problem affecting over 90 million adults in the United States, However, how different chemical signals in the body respond to this disease continues to remain unclear. A new study from researchers at the University of Chicago published in the Journal of Clinical Endocrinology and Metabolism helps to untangle how part […]
Gut throws cells overboard when chemical insults build up
A team of Duke researchers has discovered that cells lining the gut of zebrafish—and probably humans too—have a remarkable defense mechanism when faced with certain kinds of toxins: they hit the eject button. “The gut has the challenging job of handling all the chemicals that we consume or produce, and some of those chemicals can […]
Infrared chemical imaging technology promises new precision cancer diagnosis
More than 174,000 men will be diagnosed with prostate cancer this year, according to the American Cancer Society, putting it behind only skin cancer as the most common cancer among American men. Ji-Xin Cheng, adjunct professor of Purdue’s Weldon School of Biomedical Engineering and the Department of Chemistry, says a paper in the New England […]
Pool chemical injuries led to ~13,500 ED visits in 2015-2017
(HealthDay)—Pool chemical injuries led to an estimated 13,508 U.S. emergency department visits during 2015 to 2017, and about one-third of these injuries occurred in children, according to research published in the May 17 issue of the U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report. Kayla L. Vanden Esschert, M.P.H., from the […]
Exposure to chemical in Roundup increases risk for cancer: study
Exposure to glyphosate—the world’s most widely used, broad-spectrum herbicide and the primary ingredient in the weedkiller Roundup—increases the risk of some cancers by more than 40 percent, according to new research from the University of Washington. Various reviews and international assessments have come to different conclusions about whether glyphosate leads to cancer in humans. The […]
Chemical Fumes at a California Pool Made 19 People Sick. Here's How to Stay Safe from Chlorine Exposure
Although swimming season might be over in many parts of the country, at a Southern California pool this week, 19 kids and adults fell ill after exposure to pool chemicals. Twelve children and seven adults were taken to local hospitals Wednesday night, USA Today reported. Ventura County Fire Department Captain Stan Ziegler told the Ventura […]
How axons change chemical cues to mechanical force
While today’s technology is growing increasingly wireless, the human brain still depends on neurons being directly connected to one another. Two neurons are connected when one extends its axon to the other. This extension is activated by chemical cues that cause the axon to exert a directional force. While scientists have long known of molecules […]
