Species Interactions Could Be Affected By Global Warming
2012-06-23 09:06:42

Yale and University of Connecticut researchers report that more extinctions will take place due to global warming should "scientists fail to account for interactions among species in their models." According to Phoebe Zarnetske, primary author and postdoctoral fellow at Yale´s School of forestry & Environmental Studies department, “Currently, most models predicting the effects of climate change treat species separately and focus only on climatic and environmental drivers."...

When first exposed to cocaine, the adolescent brain launches a strong defensive reaction designed to minimize the drug's effects, Yale and other scientists have found. Now two new studies by a Yale team identify key genes that regulate this response and show that interfering with this reaction dramatically increases a mouse's sensitivity to cocaine. The findings may help explain why risk of drug abuse and addiction increase so dramatically when cocaine use begins during teenage years....

Antarctica Fish Threatened By Climate Change
2012-02-14 04:19:52

A Yale-led study of the evolutionary history of Antarctic fish and their "anti-freeze" proteins illustrates how tens of millions of years ago a lineage of fish adapted to newly formed polar conditions — and how today they are endangered by a rapid rise in ocean temperatures. "A rise of 2 degrees centigrade of water temperature will likely have a devastating impact on this Antarctic fish lineage, which is so well adapted to water at freezing temperatures," said Thomas Near, associate...

Road Runoff Spurring Spotted Salamander Evolution
2012-02-02 05:00:31

Spotted salamanders exposed to contaminated roadside ponds are adapting to their toxic environments, according to a Yale paper in Scientific Reports. This study provides the first documented evidence that a vertebrate has adapted to the negative effects of roads apparently by evolving rapidly. Salamanders breeding in roadside ponds are exposed to a host of contaminants from road runoff. Chief among these is sodium chloride from road salt, which reaches average concentrations of 70 times...

The Elusive G-spot: Even Scientists Can’t Find It!
2012-01-20 14:38:24

Many an intrepid lover has sought in vain for that legendary spring of erogenous pleasure known in pop culture simply as ℠the G-spot´. Yet mounting research suggests that the mythical female sexual organ may be just that: a myth. A team of scientists recently reviewed some 100 scientific studies on sexuality conducted over the past sixty years, and they say there´s simply no conclusive evidence corroborating the existence of the G-spot. “Objective measures have...

Yale researchers have uncovered the molecular tricks used by bacteria to fight the effects of fluoride, which is commonly used in toothpaste and mouthwash to combat tooth decay. In the Dec. 22 online issue of the journal Science Express, the researchers report that sections of RNA messages called riboswitches — which control the expression of genes – detect the build-up of fluoride and activate the defenses of bacteria, including those that contribute to tooth decay. "These...

Yale Cancer Center researchers have shown that a tiny genetic variation predicts chances of survival and response to treatment for patients with ovarian cancer. The findings, published in the journal Oncogene, provide new insights into the biology of a new class of cancer marker and suggest a genetic test may help guide the treatment of women with ovarian cancer. "This gives us a way to identify which women are at highest risk for resistance to platinum chemotherapy, the standard...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
