Ever wanted to never have a tooth filled again? Fruit bats know the secret of staving off tooth decay. They eat sugary fruit, but their teeth stay healthy. Now dentists hoping the bats' secret could help them cut down on drilling and filling patients' teeth.
Physicists and radiologists have found surprising similarities between the structure of bones and the structure of galaxies.
They are examining whether the methods describing the distribution of galaxies within the universe could be used to predict the risk of broken bones among people. Bones are examined using Magnetic Resonance Tomography, with the structural images then fed into the same computer programs employed for mapping outer space. The result is a unit of measurement that serves as a guide to bone fracture susceptibility.
Organic solar cells provide new hope for future energy generation, and researchers in Dresden now want to make this option commercially viable.
It’s a fascinating proposition: once the technology’s weak spots are overcome - low durability, limited efficiency - then these ultra-thin and flexible solar cells could see almost unlimited scope, being transferred onto facades, cars, mobile phones and even handbags.
We are joined on the subject of "Innovations for solar technology" by Prof. Eicke Weber, director of the Institute for Solar Energy Systems (ISE) in Freiburg.
Researchers in Ulm have discovered a possible solution to gum disease by studying fruit bats. Although the winged mammals live solely off sweet fruit, their gums are in good condition.
The surface of their teeth is composed of little bumps similar to lotus leaves that repel dirt and bacteria. The scientists are now looking for a way of coating human teeth in a similar nanostructure.
