CHAMPAIGN, Ill. —Well-intentioned policies to make achieving tenure more family-friendly actually have negative consequences for the salaries of college faculty members, a study co-written by a University of Illinois labor and employment relations professor shows.

CHAMPAIGN, Ill. — The Obama administration's controversial proposal to "means-test" Medicare recipients is ostensibly aimed at generating more cash for the government from those who can afford it – or squeezing more money out of upper-income seniors, depending upon one's point of view. But according to a University of Illinois expert on retirement benefits, the Medicare program is already means-tested.

Law professor Richard L. Kaplan says whenever the issue of cutting Medicare emerges, one of the first ideas to "fix" the program is to make its upper-income beneficiaries pay more.

CHAMPAIGN, Ill. — For companies with employees around the globe, the challenges of distance, diversity and technology may threaten team cohesiveness among their long-distance workers. But according to a new study by a University of Illinois business professor, out of sight doesn't necessarily have to mean out of mind for virtual teams.

Predecessors to dinosaurs missed the race to fill habitats emptied when nine out of 10 species disappeared during Earth's largest mass extinction 252 million years ago.

Or did they?

That thinking was based on fossil records from sites in South Africa and southwest Russia.

It turns out, however, that scientists may have been looking in the wrong places.

Newly discovered fossils from 10 million years after the mass extinction reveal a lineage of animals thought to have led to dinosaurs in Tanzania and Zambia.

Many scientists have thought that dinosaur predecessors missed the race to fill habitats emptied when nine out of 10 species disappeared during the Earth's largest mass extinction, approximately 252 million years ago. The thinking was based on fossil records from sites in South Africa and southwest Russia.

It turns out that scientists may have been looking for the starting line in the wrong places.

The results of Chen's research were published online in the journal Proceedings of the National Academy of Sciences. Katrina Wisdom, a Duke undergraduate and a Pratt Research Fellow in Chen's lab at the time of this study, was the paper's co-first author.

Tiny 1,900 million-year-old fossils from rocks around Lake Superior, Canada, give the first ever snapshot of organisms eating each other and suggest what the ancient Earth would have smelled like.

The fossils, preserved in Gunflint chert, capture ancient microbes in the act of feasting on a cyanobacterium-like fossil called Gunflintia – with the perforated sheaths of Gunflintia being the discarded leftovers of this early meal.

(CHICAGO) - A team of international researchers led by Northwestern Medicine scientists has identified how a defective protein plays a central role in a rare, lethal childhood disease known as Giant Axonal Neuropathy, or GAN. The finding is reported in the May 2013 Journal of Clinical Investigation.

JUPITER, FL, April 29, 2013 – Proteins, the workhorses of the body, can have more than one function, but they often need to be very specific in their action or they create cellular havoc, possibly leading to disease.

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have uncovered how an enzyme co-factor can bestow specificity on a class of proteins with otherwise nonspecific biochemical activity.

Researchers at the University of Arizona's Tumamoc Hill have digitized 106 years of growth data on individual plants, making the information available for study by people all over the world.

Knowing how plants respond to changing conditions over many decades provides new insights into how ecosystems behave.

The permanent research plots on Tumamoc Hill represent the world's longest-running study that monitors individual plants, said co-author Larry Venable, director of research at Tumamoc Hill.

The food dye Brilliant Blue FCF (BB FCF) could be a useful tool in the development of treatments for a variety of conditions involving the membrane channel protein Pannexin 1(Panx1), according to a study in The Journal of General Physiology. Panx1, which is involved in signaling events leading to inflammation and cell death, has been implicated in such diverse diseases as Crohn's, AIDS, melanoma, epilepsy, spinal cord injury, and stroke, among others.

COLUMBUS, Ohio – A Big Data analysis that integrates three large sets of genomic data available through The Cancer Genome Atlas has identified 37 RNA molecules that might predict survival in patients with the most common form of breast cancer.

PHILADELPHIA—The well-studied protein VEGF does not appear to have any prognostic or predictive value for men with locally advanced prostate cancer, researchers from the Department of Radiation Oncology at Thomas Jefferson University Hospital and other institutions found in a retrospective study published online April 25 in the journal BMC Radiation Oncology.

DRY TORTUGAS, Fla. – Nesting green sea turtles are benefiting from marine protected areas by using habitats found within their boundaries, according to a U.S. Geological Survey study that is the first to track the federally protected turtles in Dry Tortugas National Park.
