Genes linked to baldness, missing teeth Scientists have for the first time linked genetic anomalies with baldness and abnormal tooth development. Nylon may take X rays into digital age A new composite material could be the key to developing digital X rays, making traditional X-ray film obsolete. Missing protein helps mice to bone up Osteocalcin, one of several proteins found inside bone, appears to inhibit the bone-forming activity of cells called osteoblasts. Humble crop goes high-tech Cassava, the crop that feeds millions of poor people everyday, may become more nutritious and easy to grow in the next decade, thanks to genetic engineering. An American artifact in Siberia A distinctive type of stone point fashioned by North American settlers as early as 11,200 years ago has now been found in Siberia, raising questions about the origins of stone-tool technology in the New World.
Researchers report two well-preserved skeletons of extinct primates found in a Brazilian cave.
A small, previously unknown living monkey is discovered in the Brazilian rain forest. In rare instances, people can live a healthy, long life even if they possess the genetic mutation that causes Huntington's disease, normally a fatal neurodegenerative affliction. A shift toward drier conditions in Africa more than 2.5 million years ago may have propelled profound evolutionary changes in mammals, including our own hominid ancestors. Flaws of the Heart Heart defects cause many cases of sudden death in athletes.
