Keep feet on ground, it's not all about hair


THERE's nothing better for children's feet than walking barefoot, say experts.

Podiatrist Tracy Byrne says walking barefoot "develops muscles and ligaments of the foot, increases strength of the foot's arch and improves awareness of where we are in relation to the space around us".


According to US Surgeon General Regina M Benjamin, too many women are skipping exercise out of fear of having a bad hair day.

Benjamin recently spoke at a trade show in Atlanta that drew 60000 hair stylists, about the importance of helping women look good while still finding time to participate in daily exercise.

The surgeon general said manywomen were using their hair as an excuse not to exercise. Benjamin said that many women, particularly black women like her, invested lots of money in hair products.


A new spider-like micromachine could repair blood vessels.

According to New Scientist, Ayusman Sen of Pennsylvania State University and his colleagues have created a self-propelling microspider using spheres of less than a micrometre wide.

In the future, more sophisticated micro-spiders attached to nanobots that detect chemicals which are secreted by damaged tissue could swim through the bloodstream.

These could result in weaving a medical glue to help heal tears in vessel walls.


To reduce heartburn, don't eat for four hours before bedtime.

In a study published in The American Journal of Gastroenterology, researchers recruited 350 people and observed whether their night-time eating habits predicted their risk of heartburn and gastroesophageal reflux disease.

They found that eating within three hours of going to bed was associated with a sevenfold increase in the risk of reflux symptoms. According to researchers, three to four hours is the threshold - that is roughly the time it takes for food to clear the stomach.
