Health Research: High-fat diet may alleviate mitochondrial disease ♦ Eye color may be linked to alcohol dependence ♦ July 4: Short-term spike in particulate matter in US

High-fat diet may alleviate mitochondrial disease Mice that have a genetic version of mitochondrial disease can easily be mistaken for much older animals by the time they are nine months old: they have thinning grey hair, osteoporosis, poor hearing, infertility, heart problems and have lost weight. Dietary fat, coupled with a natural hormone, can relieve symptoms in these mice.
Eye color may be linked to alcohol dependence People with blue eyes might have a greater chance of becoming alcoholics, according to a unique new study
For women with bipolar disorder, sleep quality affects mood Poor sleep is associated with negative mood in women with bipolar disorder, according to researchers. Bipolar disorder is a brain disorder that causes unusual shifts in mood, energy, activity levels and the ability to carry out day-to-day tasks. The condition is marked by extreme mood episodes characterized as manic (highs), depressive (lows) or mixed
Research reveals new insights into a key antibiotic target in the fight against TB A key process in the bacterium that causes tuberculosis has been unraveled by researchers, potentially paving the way for new antibiotics to fight the disease. TB is one of the world's top infectious killers, causing 1.5 million deaths every year. The TB bacterium Mycobacterium tuberculosis (Mtb) is estimated to be present in up to a third of the world's population, although active TB only develops in around one in 10 cases.
July 4: Short-term spike in particulate matter in US From the founding of America, the Fourth of July has been synonymous with fireworks. A new study quantifies the surge in fine particulate matter -- particles that are two and one half microns in diameter (PM2.5) -- on July 4, using observations from the 315 US air quality monitoring sites that operated from 1999 to 2013. While scientists have known that fireworks displays produce a surge in fine particulates, the new study is the first nationwide quantitative analysis of the effects.
