How to hit home runs

A study published in the American Journal of Physics found that the speed of a baseball bat when it hits the ball is the most important factor in hitting a home run. Curve balls are thrown with topspin, which automatically gives them backspin and lift upon impact, making them carry further than fastballs.

Men, women perceive Muslim world differently

A new study reveals that Western perceptions of the Muslim world vary greatly depending on gender. Women tend to perceive Islamic culture as sensual and attractive, while men often view it as uncivilized and barbaric. This disparity highlights a complex interplay between cultural stereotypes and media representation.

Virginia Tech's 'X' officially number 3

The Virginia Tech 'X' supercomputer boasts 10.28 teraflops performance, a remarkable feat considering its construction took just two months and $5.2 million price tag. This achievement ranks X as the third fastest globally, outperforming many high-end supercomputers

Women and men differ on adopting healthy behaviors

A recent study found that men are more likely than women to adopt healthy behaviors, such as regular exercise and quitting smoking. Women, on the other hand, were less confident in their ability to make these changes. The researchers hope their findings can be used to assist both men and women with adopting healthier lifestyles.

Buckwheat may be beneficial for managing diabetes

Researchers found that buckwheat extract can reduce blood glucose concentrations in rats with chemically-induced diabetes by 12-19%, suggesting its potential as a management aid. The active component chiro-inositol may play a role in this effect, although further studies are needed to confirm the results.
