A recent likely comet collision on Jupiter caused a minor sensation, but new research shows that similar impacts on Earth are most likely not responsible for any of the planet’s mass extinctions, nor have they been responsible for more than one minor extinction event.

Everyone knows that vitamins “from A to zinc” are important for good health. Now, a new research study suggests that zinc may be pointing the way to new therapeutic targets for fighting infections. Specifically, scientists found that zinc not only supports healthy immune function, but increases activation of the cells (T cells) responsible for destroying [...]

Assisted reproductive techniques alter the expression of genes that are important for metabolism and the transport of nutrients in the placenta of mice. The results underscore the need for greater understanding of the long-term effects of new assisted reproductive techniques in humans.
Striking differences in the risk factors for developing heart failure (HF) and patient prognosis exist between men and women. Men and women may also respond differently to treatment, raising concerns about whether current practices provide the best care and reinforcing the urgency for sex-specific clinical trials for HF, according to a new review article.
Mine shafts on the point of being closed down could be used to provide geothermal energy to local towns. The method engineers have developed makes it possible to estimate the amount of heat that a tunnel could potentially provide.

A long-term study of over 8,700 middle-aged men and women provides some of the first race- and gender- specific data on the cholesterol effects of physical activity, with the interesting result that women, particularly African-American women, experience greater benefits in their cholesterol levels as a result of exercise than men.

A new analysis of the remains of a Tyrannosaurus rex (T. rex) that roamed Earth 68 million years ago has confirmed traces of protein from blood and bone, tendons, or cartilage. The findings is the latest addition to an ongoing controversy over which biochemical remnants can be detected in the dinosaur.
