Recently discovered species gain protection
The chestnut-capped piha is an unassuming robin-sized bird restricted to a few tiny remnant forest patches in the Antioquia Department of Colombia, in the Central Cordillera of the Andes. It is so restricted in its distribution that it evaded discovery until 1999, and has been identified by the Alliance for Zero Extinction as a priority conservation species (see <A HREF="http://www.zeroextinctio...Hormone regimen and how recently used may determine cancer risk
A new study of 3,823 post-menopausal women found that continuous combined hormone therapy(estrogen combined with 25 to 31 days per month of progestin use) was associated with an increased breast cancer risk among current users of the regimen who had been taking it for five or more years. The study however did not find any association// between use of continuous combined hormone therapy and breast...Dogs Were Domesticated Recently Only
Dogs were domesticated by human beings only as recently as between 13,000 and 17,000 years ago, according to a recent study. The earlier theories contend that the bond // lasted since 135,000 years ago. The study was conducted by Darcy Morey, and takes canine burials into consideration. Researchers found that though earliest known buried dog dates to around 17,000 years ago in central Russia, the...Recently discovered deep-sea reefs catch the attention of the drug discovery team
Researchers have always had an inkling regarding the presence of deep reefs between Miami and Bimini, when bits of reef-building corals were brought out using// the surface-operated dredge and grab sampling equipment. But due to inadequate mapping of most parts of the ocean, these crucial areas remained under cover. In December of 2005, as part of the National Oceanic and Atmospheric...
