ANN ARBOR, Mich.— For the first time, scientists have made star-shaped, biodegradable polymers that can self-assemble into hollow, nanofiber spheres, and when the spheres are injected with cells into wounds, these spheres biodegrade, but the cells live on to form new tissue.(more…)
*Tibetian Terrier dogs could play key role in developing therapy for early-onset Parkinson’s*
COLUMBIA, Mo. – University of Missouri researchers believe both man and animal will benefit from their discovery that the same gene mutation found in Tibetan Terrier dogs can also be found in a fatal human neurological disorder related to Parkinson’s disease.
If it was easy to learn, it will be easy to remember. Psychological scientists have maintained that nearly everyone uses this simple rule to assess their own learning.
Now a study published in an upcoming issue Psychological Science, a journal of the Association for Psychological Science, suggests otherwise: “Individuals with different theories about the nature of intelligence tend to evaluate their learning in different ways,” says David B. Miele of Columbia University, who conducted the study with Bridgid Finn of Washington University in St. Louis and Daniel C. Molden of Northwestern University. (more…)
ANN ARBOR, Mich. — The ongoing spread of non-native mussels in the Great Lakes has caused “massive, ecosystem-wide changes” throughout lakes Michigan and Huron, two of the planet’s largest freshwater lakes, according to a new University of Michigan-led study.
The blitzkrieg advance of two closely related species of mussels—the zebra and quagga—is stripping the lakes of their life-supporting algae, resulting in a remarkable ecological transformation and threatening the multibillion-dollar U.S. commercial and recreational Great Lakes fisheries. (more…)
A University of Exeter researcher has revealed how he discovered Apple iPhones and iPads are tracking every movement of their owners and storing it in a file on the device.
Dr Alasdair Allan, a Senior Research Fellow in the Astrophysics department, came across the find while looking at programmes on the iPhone with security expert, Pete Warden. (more…)

PASADENA, Calif. — NASA’s Mars Reconnaissance Orbiter has discovered the total amount of atmosphere on Mars changes dramatically as the tilt of the planet’s axis varies. This process can affect the stability of liquid water, if it exists on the Martian surface, and increase the frequency and severity of Martian dust storms.
Researchers using the orbiter’s ground-penetrating radar identified a large, buried deposit of frozen carbon dioxide, or dry ice, at the Red Planet’s south pole. The scientists suspect that much of this carbon dioxide enters the planet’s atmosphere and swells the atmosphere’s mass when Mars’ tilt increases. The findings are published in this week’s issue of the journal Science. (more…)
COLUMBUS, Ohio – Even temporary “breakups” can be distressing for some people – at least when it comes to their favorite television programs.
A new study examined how college-aged television viewers reacted when their favorite shows went off the air or were replaced with reruns as a result of the television writers’ strike of 2007-08.
The results revealed the important role television plays in the lives of some viewers – particularly those who use television for companionship and those who feel they have a strong “relationship” with their favorite TV characters. (more…)
