Red flag for repetitive stress injuries identified for first time in humans

...herapy. Employers and workers know the dramatic impact of RMIs, which cause pain, loss of function and close to a third of missed workdays in the United States, at a cost of $20 billion a year in workers' compensation. In previous studies, the researchers pinpointed these early warning signals in a r...

...wide range of traits, including those that have an impact on health and disease.? The branch of the canine family tree that includes domestic dogs diverged from that of the gray wolf more than 15,000 years ago. Due to selective breeding by humans throughout history, dogs today exhibit an extremely wide ra...

Penn researchers show how nanocylinders deliver medicine better than nanospheres

While these findings could impact the way lung cancer is treated, this discovery of how to more effectively deliver drugs to the body could also improve the treatment of such other illnesses as cardiovascular disease as well as other types of cancers. This discovery is also helpi...

The paper cites that establishing an injury rate for surfing is not just of academic or general interest, but also has implications for the insurance industry and for schools that may want to ...

Mimicking how the brain recognizes street scenes

At last, neuroscience is having an impact on computer science and artificial intelligence (AI). For the first time, scientists in Tomaso Poggio's laboratory at the McGovern Institute for Brain Research at MIT applied a computational model of how the brain processes visual information to a co...

The behaviours that we observe will impact upon the genetic diversity of fur seal populations and may have helped them recover so successfully from near extinction only 100 years ago. This could in turn affect how well they respond to future challenges such as climate change." Antarctic fu...
