A battery-free sweat sensor could make levodopa monitoring faster and more personalized for people with Parkinson’s disease. For people with Parkinson’s disease, the effect of a levodopa dose can fade abruptly, allowing movement problems to return before the next scheduled dose. Engineers and neuroscientists at the University of California San Diego have developed a soft [...]

New research calls for aquatic deoxygenation to be recognized as a critical planetary process under threat. Oxygen is declining across oceans, coastal waters, rivers, lakes and streams, threatening the organisms and chemical processes that depend on it. A review led by researchers at UC San Diego’s Scripps Institution of Oceanography warns that this widespread deoxygenation [...]

A major study found that common dementia risks may have a much stronger impact on women’s brains than previously recognized. Women may not only experience some dementia risk factors more often than men, but those risk factors may also have a stronger effect on their cognitive health, according to new research from the University of [...]
