West Africa, sub-Saharan Africa and South East Asia are most at risk from bat viruses ‘spilling over’ into humans resulting in new emerging diseases, according to a new global map compiled by scientists at UCL, the Zoological Society of London (ZSL) and the University of Edinburgh. (more…)

Research tracks relationships between CEO greed and company performance
That gut feeling many workers, laborers and other underlings have about their CEOs is spot on, according to three recent studies in the Journal of Management, the Journal of Management Studies and the Journal of Leadership and Organizational Studies that say CEO greed is bad for business. (more…)
As women age, key breast cells ignore their surroundings, Berkeley Lab scientists find
Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have gained more insights into why older women are more susceptible to breast cancer. They found that as women age, the cells responsible for maintaining healthy breast tissue stop responding to their immediate surroundings, including mechanical cues that should prompt them to suppress nearby tumors. (more…)
Michigan State University researchers have identified a genetic mutation in Doberman pinschers that causes albinism in the breed, a discovery that has eluded veterinarians and breeders worldwide up until now.
Paige Winkler, a doctoral student in the College of Veterinary Medicine, co-led the study with Joshua Bartoe, an assistant professor in the Department of Small Animal Clinical Sciences, and discovered a mutated gene that is associated with a form of albinism in humans. (more…)
ANN ARBOR — The sponginess of the environment where human embryonic stem cells are growing affects the type of specialized cells they eventually become, a University of Michigan study shows.
The researchers coaxed human embryonic stem cells to turn into working spinal cord cells more efficiently by growing the cells on a soft, utrafine carpet made of a key ingredient in Silly Putty. Their study is published online at Nature Materials on April 13. (more…)
ANN ARBOR — A tiny, transparent fish embryo and a string of surprises led scientists to a deeper understanding of the perplexing link between low calcium and colon cancer.
By studying zebrafish embryo skin, University of Michigan researchers decoded cell messages underlying abnormal colonic cell growth of the kind that can lead to tumors and colon cancer in calcium deficient individuals. They have also tested this new mechanism in human colon cancer cells. (more…)
Opening the door to more sophisticated investigation of sperm locomotion and biophysics, researchers from UCLA’s Henry Samueli School of Engineering and Applied Science have identified previously unobserved swimming patterns in human and horse sperm cells.
This research, published in Scientific Reports, a journal of the Nature Publishing Group, could lead to a deeper understanding of how sperm move on their way to fertilization or other functions and how they react when encountering various toxins or chemicals. (more…)
Charles Wright, hailed as one of the leading American poets of his generation, has been named the winner of Yale’s 2013 Bollingen Prize for American Poetry.
The Bollingen Prize in American Poetry is among the most prestigious prizes given to American writers. Established by Paul Mellon in 1949, it is awarded biennially by the Yale University Library to an American poet for the best book published during the previous two years or for lifetime achievement in poetry. The prize includes a cash award of $150,000. (more…)
