Tooth and Jaw Fossils Point to Man’s Earliest Ancestor

by Demo User

The lineages of chimpanzees and human beings may have split several hundred thousand years earlier than previously thought and in the Eastern Mediterranean region and not in Africa, according to an international research team. Using computer tomography, the researchers investigated the fossil of a lower jaw from Greece and an upper molar from Bulgaria and concluded that they belonged to pre-humans.

New low-cost imaging device could facilitate early detection of dental caries

by Demo User

Affecting 60–90 percent of schoolchildren and nearly all adults, dental caries is the most prevalent oral disease around the globe. As current detection methods, such as visual inspection and radiographs, lack sufficient specificity and sensitivity to detect caries at an early stage, researchers seeking an improved means of detection have now described a new method enabling much earlier detection using inexpensive long-wavelength infrared imaging.
