Evolutionarily speaking, "the orthopedic surgeon is a very recent invention," the Weizmann Institute's Elazar Zelzer told BioWorld Today. But fracture healing is "a robust process."
From a purely scientific standpoint, the news about the Ebola outbreak has been encouraging. New genomic technologies enable unprecedented surveillance of the virus. There are drugs and vaccines in clinical trials. And in response to the urgency of the crisis, both drugmakers and regulatory agencies are making efforts to expedite the process of getting weapons against Ebola through the regulatory process and into the field, where they are needed.
Researchers have shown that flavanols – a compound found, among other foods, in cocoa beans – reversed age-related memory declines in healthy individuals in their 50s and 60s.
