A year-long study by Yale University paleontologists concludes that two related horned dinosaurs are different animals and not adult and juvenile versions of the same.
“We’re saying, ‘No, they’re different,’” said Nicholas R. Longrich, a postdoctoral fellow in Yale’s Department of Geology and Geophysics and the lead author of the study. “They’re separate animals.” (more…)
Parasitic wasps using tiny insects known as aphids as living nurseries for their brood can sniff out whether the host insect is protected by symbiotic bacteria, researchers have discovered.
A research team including Martha (Molly) Hunter from the department of entomology in the University of Arizona’s College of Agriculture of Life Sciences has disentangled relationships in an assembly of players that resemble Russian dolls: a bacterium that lives inside a tiny insect, a virus that infects those bacteria, and a parasitic wasp that lays its eggs in the insect.
In a war between parasite and host, the parasitic wasp, Aphidius ervi, and the pea aphid, Acyrthosiphon pisum, are locked in a battle for survival. (more…)
ANN ARBOR, Mich.— Fifty million years ago, India slammed into Eurasia, a collision that gave rise to the tallest landforms on the planet, the Himalaya Mountains and the Tibetan Plateau.
India and Eurasia continue to converge today, though at an ever-slowing pace. University of Michigan geomorphologist and geophysicist Marin Clark wanted to know when this motion will end and why. She conducted a study that led to surprising findings that could add a new wrinkle to the well-established theory of plate tectonics – the dominant, unifying theory of geology. (more…)
EAST LANSING, Mich. — Often faced with overwhelming anxiety, patients newly diagnosed with lung cancer can find themselves in distress, and new research recommends nurses play a key role in alleviating concerns, leading to a better quality of life for patients. (more…)
COLUMBIA, Mo. – In 2007, a controversial pesticide was approved by the Food and Drug Administration for use on fruit and vegetable crops, mainly in California and Florida. Farm workers and scientists protested the approval of the pesticide because its active ingredient, methyl iodide, is a known carcinogen. Now, MU researchers are studying the molecular structure of the pesticide to determine if the product could be made more efficient and safer for those living near, and working in, treated fields.

The number of people living in China’s cities, which last year for the first time surpassed 50 percent of the national population, is considered a boon for the consumer goods market. That is based on the assumption that there will be more families with more disposable income when poor farmers from China’s countryside move to cities and become middle-class industrial and office workers.

*Berkeley Lab Researchers Resolve Controversy Over Gallium Manganese Arsenide that Could Boost Spintronic Performance*
A long-standing controversy regarding the semiconductor gallium manganese arsenide, one of the most promising materials for spintronic technology, looks to have been resolved. Researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) in collaboration with scientist from University of Notre Dame have determined the origin of the charge-carriers responsible for the ferromagnetic properties that make gallium manganese arsenide such a hot commodity for spintronic devices. Such devices utilize electron spin rather than charge to read and write data, resulting in smaller, faster and much cheaper data storage and processing. (more…)
