Oldest fossil human protein ever sequenced

...ound that the Neanderthal sequence was the same as modern humans. The team also found a marked difference in the sequences of Neanderthals, humans, chimpanzees and orangutans from that of gorillas and most other mammals. This sequence difference is at position nine where the amino acid hydroxyproline is re...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

...fections is around $10 billion a year. Worse, with modern rapid transit and world travel, multiple drug-resistant bacteria could potentially spread beyond the isolated confines of a hospital and into the general population. If one could design drugs to halt the enzymes that make mutations in bacteria, this...

Researchers find gene that may be at root of potato blight

The scientists describe the gene, called Avr3a, in a study that appears online in the early edition of the Proceedings of the National Academy of Sciences. Researchers call Avr3a an avirulence ge...

Butterfly migration could be largest known

...t UC Davis. "This may be the biggest migration of modern times," Shapiro said. Shapiro said he is getting reports of "billions" of butterflies around Trona, near Death Valley, and in the San Fernando Valley. More waves of butterflies are likely to appear in central California over the next few weeks as th...

UCLA study assesses cost-effectiveness of Hepatitis B drugs

Now, through smaller research studies using modern technology, they have identified the Antarctic Circumpolar Current, a powerful force flowing from west to east moving 145 million cubic meters of water per second, more than the combined flow of all world rivers. Piecing together the history of mari...

Studies reveal how plague disables immune system, and how to exploit the process to make a vaccine

He added that the fact that the walls of the groove are covered with enamel indicates the groove is not a product of post-mortem exposure and splitting but rather is the natural design of the tooth. "The groove in these teeth would h...
