Okay Daredevil, this will take some time and some work, but so does playing a guitar - a group of biologists have determined that humans can learn to echolocate the way bats do.

It's well known that blind people develop keener hearing and they even learn to help navigate using echoes of sounds, but that ability to determine locations spatially is suppressed by the 'precedence effect' - which occurs when a second sound arrives rapidly and becomes fused with the first so that the first is dominant.  

It's time to stop oppressing breasts, according to a massive 15-year investigation by professor Jean-Denis Rouillon, from the University of Besançon in eastern France.

Bras are a false necessity, he said in April, and his evidence was gained by carefully measuring changes in the orientation of breasts belonging to hundreds of women aged between 18 and 35 using a slide rule and a caliper. At least we think. The results weren't published, he just said them on a radio show, but that was enough to get him covered in misogynistic sites like the New York Times and Reuters. Oh, and most importantly, my blog.

Facial hair can be a status symbol - as Sikh women say, they know their men have a full motor under the hood - but does it protect against sun damage, as commonly believed?

The sun's most harmful rays are UV - ultraviolet - radiation. Though they are too high in frequency for us to see, that they are still hitting you is why you can still get burned on a day when the sun is not shining brightly. In Australia, which has "one of the world's highest incidences of UVR-related conditions and illnesses", like skin cancer and melanoma, researchers did a study to examine the truth of that hair-protection business.
