Worm lizards dispersed by 'rafting' over oceans, not continental drift

Science News Daily - March 31, 2015 - 8:58pm
Tiny, burrowing reptiles known as worm lizards became widespread long after the breakup of the continents, leading scientists to conclude that they must have dispersed by rafting across oceans soon after the extinction of the dinosaurs, rather than by continental drift as previously thought.

Tiny songbird discovered to migrate non-stop, 1,500 miles over the Atlantic

Science News Daily - March 31, 2015 - 8:58pm
For the first time biologists report 'irrefutable evidence' that tiny blackpoll warblers complete a nonstop flight from about 1,410 to 1,721 miles (2,270 to 2,770 km) in just two to three days. For this work the scientists fitted geolocator packs on 20 birds in Vermont and 20 more in Nova Scotia. They were able to recapture three birds from the Vermont group and two from the Nova Scotia group for analyses.

Discovering missing body parts of ancient fossils: Waves and storms lifted fossils off the seafloor 550 million years ago

Science News Daily - March 31, 2015 - 5:06pm
Certain specimens of the fossil Dickinsonia are incomplete because ancient currents lifted them from the sea floor, a team of paleontologists has found. Sand then got deposited beneath the lifted portion, the researchers report, strongly suggesting that Dickinsonia was mobile, easily separated from the sea floor and not attached to the substrate on which it lived.

Daily dam releases on Massachusetts' deerfield river reduce downstream flows

Science News Daily - March 31, 2015 - 1:52pm
In the first-of-its-kind study of the environmental effects of hydropeaking, that is releasing water at hydropower dams to meet peak daily electricity demand, two researchers say their unexpected findings suggest that about 10 percent of released water may be permanently lost, making that water unavailable to downstream users and wildlife.

Stereotypes persist that class, privilege determine intellect and success

Science News Daily - March 31, 2015 - 1:52pm
A meritocracy holds that if you work hard enough, you can succeed in life, regardless of race, religion, gender or social status. But a new study suggests that, despite egalitarian efforts to downplay class as a forecaster for intelligence and achievement, many people still believe their destiny is tied to their station in life.

Soil organic matter susceptible to climate change

Science News Daily - March 31, 2015 - 1:52pm
Soil organic matter, long thought to be a semi-permanent storehouse for ancient carbon, may be much more vulnerable to climate change than previously thought. Scientists have found that the common root secretion, oxalic acid, can promote soil carbon loss by an unconventional mechanism -- freeing organic compounds from protective associations with minerals.

Exercise largely absent from US medical school curriculum, study shows

Science News Daily - March 31, 2015 - 1:51pm
Fewer than half of the physicians trained in the United States in 2013 received formal education or training on the subject of exercise, according to new research. "There are immense medical benefits to exercise; it can help as much as medicine to address some health concerns," said a national expert on the benefits of physical activity. "Because exercise has medicinal as well as other benefits, I was surprised that medical schools didn't spend more time on it."
