How the elephant got its trunk, the deer its antlers and the rattlesnake its rattles may seem like disparate questions of developmental biology, but the origins of these novelties, according to the genes of butterflies, may have much in common.
Looking deep within the genes of three very different kinds of animals, scientists have found enough molecular evidence to finally fell the animal kingdom's old family tree.
By shining a laser from space onto the Antarctic and Greenland, scientists may soon peel away some of the mystery surrounding the fate of the massive ice sheets that, through natural fluctuation or human-induced climate change, could drastically alter the levels of the world's oceans.
La Nina may get the attention, but if forecasts of unusually wild weather this spring come true, lesser-known forces like "zonal jet streams" and "Bermuda highs" will be responsible.
This winter the Antarctic Muon and Neutrino Detector Array or AMANDA, a novel telescope set kilometers deep in the ice at the South Pole, began its search for the ghost-like cosmic neutrino.
The culture of a school -- a web of values, traditions and symbols -- can be toxin or tonic for education reform. Ignoring this powerful variable, however, can be a fatal mistake in reform attempts, according to University of Wisconsin-Madison researchers.
A University of Wisconsin-Madison engineer has developed a new guardrail design made from composite materials that is potentially safer than traditional highway guardrails.
They look more like stray computer parts than precision medical tools, but Amit Lal's research creations could give surgeons an incomparable new edge in medicine.
Learning to spot signs of anger early becomes a finely honed survival skill for children who have suffered severe abuse. A new study by psychologist Seth Pollak suggests that this survival skill may actually trigger biological changes, altering the way the brain processes anger.
Transferring desirable genes into crops is a high-tech game of chance, with success rates running about one in 1,000. But the odds get a whole lot better when you remove gravity from the mix.
