Scientists Find Offspring of Tortoises Believed Extinct
2012-01-09 13:25:27

A giant Galapagos tortoise species believed to have been extinct for 150 years may actually still be alive, researchers from Yale University have discovered. According to Telegraph Science Correspondent Nick Collins, experts believe that the species in question, Chelonoidis elephantopus, died out shortly after Charles Darwin's visit to the Galapagos Islands in 1835. However, the researchers say that they have found hybrid tortoises on the island of Isabela "that appear to have C....

A drastic decrease in atmospheric carbon dioxide levels appears to have been the catalyst that led to the formation of the Antarctic ice sheet, according to a new study published December 1 in the journal Science. The research, which was completed by an international team of experts led by Mark Pagani of Yale University, "helps solve a long-standing scientific puzzle and confirms the power of CO2 to dramatically alter global climate," according to a Thursday press release from the...

New research is allowing scientists to learn what the colors of fossilized moths would have been. Maria McNamara, a paleobiologist and postdoctoral researcher at Yale University was examining fossils from oil shale in Germany when she came across the remains of several moth species, all belonging to a group called lepidopterans, which also includes butterflies. “Until now, we had no idea what colors ancient moths and butterflies had,” McNamara relates to Stephanie Pappas of...

Researchers at Yale University are studying how two types of nanoscale structures on the feathers of birds produce brilliant and distinctive colors. The researchers are hoping that by borrowing these nanoscale tricks from nature they will be able to produce new types of lasers–ones that can assemble themselves by natural processes. The team will present their findings at the Optical Society's (OSA) Annual Meeting, Frontiers in Optics (FiO) 2011, taking place in San Jose, Calif. next...

By Rhonda Craig, Ivanhoe Health Correspondent (Ivanhoe Newswire) --Sugary cereals, syrupy snacks and toy-packed kids meals. The health industry says it´s working to regulate food marketing to children, but is it working? That´s one question researcher Marlene Schwartz, Ph.D., Deputy Director for the Rudd Center for Food Policy & Obesity at Yale University examined.   Research from Dr. Schwartz and her colleagues was presented at the Obesity Society´s 29th annual...

Yale University researchers have found one of the mechanisms that cause fat cells to lose their ability to efficiently store and use energy -- a scientific mystery and a phenomenon that contributes to a major public health problem. The Yale team discovered a mechanism that allows cellular fat droplets to expand when excess metabolic energy is present -- i.e., when the body has taken in more food than it can burn off -- helping them to take in fatty acids, the end products of our meals. The...

Breakthrough finding sheds light on fundamental biological process A team of scientists at the Gladstone Institutes and Yale University have begun to unravel the complex process by which cells take in and store microscopic fat molecules, suggesting new directions for further research into solutions for obesity and its related conditions, such as heart disease, type 2 diabetes and fatty liver disease. In a paper being published today in Cell Metabolism, Gladstone Senior Investigator...

Small bypass vessels which act as a 'back-up system' for the heart's main arteries play a significant role in reducing the mortality of patients with coronary artery disease, according to new research. Researchers from UCL, University of Bern, Yale University and other international collaborators examined the role of natural bypass vessels called coronary collaterals in patients with blocked arteries. The study, published online today in the European Heart Journal, shows that patients...
