An international research team led by Brown University has amassed the largest evolutionary tree (phylogeny) for plants. It has learned that major groups of plants tinker with their design and performance before rapidly spinning off new species. The finding upends long-held thinking that plants' speciation rates are tied to the first development of a new physical trait or mechanism. Results are published in the American Journal of Botany. Just as a company creates new, better versions of a...

Demonstrating an important milestone for the longevity and utility of implanted brain-computer interfaces, a woman with tetraplegia using the investigational BrainGate* system continued to control a computer cursor accurately through neural activity alone more than 1,000 days after receiving the BrainGate implant, according to a team of physicians, scientists, and engineers developing and testing the technology at Brown University, the Providence VA Medical Center, and Massachusetts General...

In recent years, researchers have worked to develop more flexible, functional prosthetics for soldiers returning home from battlefields in Afghanistan or Iraq with missing arms or legs. But even new prosthetics have trouble keeping bacteria from entering the body through the space where the device has been implanted. "You need to close (the area) where the bacteria would enter the body, and that's where the skin is," said Thomas Webster, associate professor of engineering and orthopaedics at...

Romping clumps of misfolded proteins are prime suspects in many neurological disorders including Alzheimer's, Parkinson's, and Creutzfeld-Jakob Disease. Those diseases are devastating and incurable, but a team of biologists at Brown University reports that cells can fix the problems themselves with only a little bit of help. The insight suggests that there are more opportunities to develop a therapy for protein misfolding than scientists had thought. "There are multiple steps that you could...

Brown University biologist uses sophisticated genomic and computational techniques in a study of deep-sea creatures to examine the origins of a diversity of life The National Science Foundation (NSF) has named its awardee for this year's Alan T. Waterman Award: Casey Dunn, a biologist at Brown University. Dunn's work involves genome analyses to better understand relationships between groups of animals.  He investigates the origins of biological complexity through work with deep-sea...

New research shows that people who receive weak but supportive evidence about a proposition are less optimistic about the outcome than people who receive no evidence at all. The "weak evidence effect" could be a useful tool in communications, from marketing to political discourse. Experiments by Brown University psychologists have produced positive evidence that people often think about positive evidence the wrong way "” if it is weak. Defying logic, people given weak evidence can...

By Lisa Chedekel, Boston University Marketing efforts that encourage mixing caffeinated "energy" drinks with alcohol often try to sway young people to believe that caffeine will offset the sedating effects of alcohol and increase alertness and stamina. But a new study led by researchers from the Boston University School of Public Health and the Center for Alcohol and Addiction Studies at Brown University has found that the addition of caffeine to alcohol -- mixing Red Bull with vodka, for...

While wealthier people have chosen alternatives to urban nursing homes, the urban poor still depend on them for long-term care. A new study led by researchers at Brown University finds that option is nevertheless slipping away. Between 1999 and 2008, nursing home closures in the United States were concentrated disproportionately in poor, urban and predominantly minority neighborhoods. Overall, the United States lost 5 percent, or 96,902, of its total nursing home beds during the decade, as...

Geologists at Brown University and the University of Washington have a cautionary tale: Lose enough species in the oceans, and the entire ecosystem could collapse. Looking at two of the greatest mass extinctions in Earth's history, the scientists attribute the ecosystems' collapse to a loss in the variety of species sharing the same space. It took up to 10 million years after the mass extinctions for the ecosystem to stabilize. The findings appear in Geology. The world's oceans are under...
