Tests show high levels of coral-harming chemical in Hawaii

Technology
Officials have found high levels of a chemical commonly used in sunscreen that is believed to harm coral reefs in bay waters off Hawaii's Big Island. The Kahaluu Bay Education Center commissioned the testing for oxybenzone at five sites in the bay on the island's west side last year, West Hawaii Today reported Sunday. The results found the chemical's concentration at one of the sites to be 262 times greater than levels considered high-risk by the U.S. Environmental Protection Agency. "That sample there is the highest we've ever measured in the world," said Craig Downs, executive director of Haereticus Environmental Laboratory, which conducted the sampling. The concentration was likely high because it was taken at a spot where people enter the water and on days with heavy beach traffic, Do...
Chemical in baked goods, flavorings may increase obesity, diabetes risk

Chemical in baked goods, flavorings may increase obesity, diabetes risk

Health
April 25 (UPI) -- An ingredient widely used in animal feed, artificial flavorings and baked goods may cause a spike in hormones that can raise the risk of diabetes and obesity, a new study says. Eating foods with propionate can increase substances in the human body that create excessive insulin and insulin resistance, according to a study published Wednesday in Science Translational Medicine. "Understanding how ingredients in food affect the body's metabolism at the molecular and cellular level could help us develop simple but effective measures to tackle the dual epidemics of obesity and diabetes," Gokhan S. Hotamışlıgil, a researcher at Harvard Chan School and study author, said in a news release. After feeding propionate to mice, the researchers observed significant weight gain and a
Death toll increases to 64 in Chinese chemical plant blast

Death toll increases to 64 in Chinese chemical plant blast

World
March 23 (UPI) -- Officials raised the death toll at a chemical plant that exploded in eastern China to 64 on Saturday and announced the rescue of a survivor two days after the blast. The pesticide plant exploded Thursday afternoon with the force of a small earthquake that reduced the building to rubble. The explosion is being blamed on a fire that broke out at the factory run by Tianjiayi Chemical in Yancheng. Rescuers pulled a man in his 40s from the rubble Saturday morning. Yancheng Mayor Cao Lubao said 28 people are still missing and about 26 of the dead have been identified. Among those who survived, 617 people sustained injuries, 21 of whom were in critical condition. The owners and directors of the chemical plant have received fines and warnings multiple times over unsafe conditi...
Study: Chemical in Roundup may increase cancer risk by 40 percent

Study: Chemical in Roundup may increase cancer risk by 40 percent

Health
Feb. 15 (UPI) -- Glyphosate, a chemical in the popular weedkiller Roundup, may elevate cancer risk in people, according to a new study. Researchers examined studies conducted between 2001 and 2018 and found that the chemical could increase the risk of Non-Hodgkin Lymphoma by up to more than 41 percent, according to new findings published this month in Science Direct. "Our analysis focused on providing the best possible answer to the question of whether or not glyphosate is carcinogenic," senior author Lianne Sheppard, a professor at the University of Washingtonsaid in a press release. "As a result of this research, I am even more convinced that it is." This new study contradicts a past report from the European Food Safety Authority that said glyphosate does not cause cancer. The United N...
Fossilized dinosaur proteins and burnt toast feature similar chemical compounds

Fossilized dinosaur proteins and burnt toast feature similar chemical compounds

Science
Nov. 9 (UPI) -- Under the right conditions, a dinosaur's soft tissue can be transformed and preserved, enabling fossilization. The process features chemical transformations similar to those that characterize browned or burnt toast. Scientists have long debated whether soft tissue can be preserved within dinosaur bones. While hard tissue -- bones, eggs, teeth, scales -- can survive for more than 100 million years, most studies suggest the proteins that form blood vessels, cells and nerves are fully degraded after 4 million years. And yet, paleontologists have regularly found organic structures similar to cells and blood vessels inside 100-million-old dinosaur bones. To better understand this paradox, researchers at Yale, the American Museum of Natural History, the University of Brussels an...
