In a systematic measurement survey, [Lucas] Portelli has shown that the ambient static and time-varying magnetic fields in laboratory incubators are large and variable: He found that they can differ by a factor of a hundred or more within and between incubators.
"These variations can be observed within the same incubator in locations that are centimeters apart," he writes in a paper published in Bioelectromagneticsearlier this month. Such magnetic fields could be a “potential confounder” of cell culture studies, he warns. …
"There are strong classical and fundamental reasons why these fields shouldn’t matter," Portelli told Microwave News, “but when you take the time to put the experimental data all together, they suggest otherwise.” Magnetic fields “may become another factor that we may just have to control,” he said.
Millions of workers in a number of industries are exposed to chemicals every day. While many of these chemicals may be harmful, only a small number are regulated in the workplace. Because of this, employees suffer more than 190,000 illnesses and 50,000 deaths annually—all related to chemical exposures. Workplace chemical exposures have been linked to cancers as well as lung, kidney, skin, heart, stomach, brain, nerve and reproductive diseases, according to the United States Department of Labor.
In this week’s issue, Ian Johnson writes about Handan, one of the ten most polluted cities in China: http://nyr.kr/17W9JhL
The photographer Sim Chi Yin travelled to Handan to document the pollution. A look at the photos: http://nyr.kr/17W9Ny2

WARNING: After looking at some of Sim Chi Yin’s photos that show how close polluting industries are allowed to operate next to agricultural areas in China; you may become less willing to buy food produced in China, or any processed foods that don’t indicate from where all of their ingredients originated. Concerns are being raised about tainted food that China may be exporting. Unfortunately, new trade agreements these days often appear to be, in effect, prioritizing enriching the executives of unscrupulous, deep-pocketed, politically powerful multinational corporations; above protecting your health. When you can, buy real food from local sustainable farmers that you trust.
