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...

Leaf Chafer Beetle

Dr. Maria McNamara of Yale University has done microscopic research that shows how the colors of fossilized beetles have shifted. This new research, published in the Proceedings of the Royal Society B, gives paleontologists greater confidence in knowing what these ancient insects actually looked like. The color information revealed by the beetles further unveils the way a particular beetle lived its life. Dr. McNamara told BBC News, “These kinds of colors have lots of visual...

Genetic parasites invaded the mammalian genome more than 100 million years ago and dramatically changed the way mammals reproduce -- transforming the uterus in the ancestors of humans and other mammals from the production of eggs to a nurturing home for developing young, a new Yale University study has found. The findings published online Sept. 25 in the journal Nature Genetics describe in unprecedented detail the molecular changes that allowed mammals to carry their developing young...

   Since the online citizen science project Planet Hunters launched last December, 40,000 web users from around the world have been helping professional astronomers analyze the light from 150,000 stars in the hopes of discovering Earth-like planets orbiting around them. Users analyze real scientific data collected by NASA's Kepler mission, which has been searching for planets beyond our own solar system – called exoplanets – since its launch in March 2009. Now...

Key To Fighting Food Cravings All In Your Head

   Researchers from Yale University and the University of Southern California, seeking new treatments to reverse the epidemic of obesity in the US, found that obese people had more difficulty resisting cravings for high-calorie foods, explaining why it might be difficult for overweight people to lose extra body mass, according to various media reports.   The study, published in the Journal of Clinical Investigation, found that thin people may be able to mentally resist...

  The same meteorite impact that caused dinosaurs to go extinct 65 million years ago also essentially wiped out ancient birds, a team of paleontologists claim in a new study. The researchers, led by Nicholas Longrich of Yale University, studied collections of approximately two dozen bird fossils of various species from the school's Peabody Museum of Natural History, as well as from the American Museum of Natural History, the University of California Museum of Paleontology, and the...

If the brain goes hungry, Twinkies look a lot better, a study led by researchers at Yale University and the University of Southern California has found. Brain imaging scans show that when glucose levels drop, an area of the brain known to regulate emotions and impulses loses the ability to dampen desire for high-calorie food, according to the study published online September 19 in The Journal of Clinical Investigation. "Our prefrontal cortex is a sucker for glucose," said Rajita Sinha,...

Hummingbird Males All A-Flutter During Courtship

How the fluttering feathers of some hummingbird species generate courtship sounds [ View the Video ] Though famous for their mid-air hovering during hunting, tiny hummingbirds have another trait that is literally telltale: males of some hummingbird species generate loud sounds with their tail feathers while courting females. Now, for the first time, the cause of these sounds has been identified: a paper published in the Sep. 9, 2011 issue of Science by Christopher Clark of Yale...

Could Stem Cells Cure Baldness?
2011-09-02 05:33:26

  Researchers from Yale University may have found a genetically natural cure for baldness - stem cells that tell a person's hair when it's time to grow. According to the scientists, these stem cells are the source of the signals that trigger hair growth and are found within the fatty layer of the skin. They report that they were able to use these cells as a catalyst to grow hair in mice--a discovery that could eventually lead to new treatment for those who have lost or are...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
