Researchers in Ireland have analyzed 50 non-documentary movies from the last four decades featuring hackers and come to some intriguing conclusions about the hacker stereotype with implications for policy makers and education.

Scientists believe they may have figured out how genetic snippets called microRNAs are able to shut down the production of some proteins.

As cancer survivors live longer, questions arise about what kind of care long-term survivors require. A recently study found 245 older married women who survived cancer had more health problems as compared to a sample of 245 married women without cancer.

Peptides that target blood vessels in fat and cause them to go into programmed cell death (termed apoptosis) could become a model for future weight-loss therapies, say researchers.

Workers exposed to tricholorethylene, a chemical once widely used to clean metal such as auto parts, may be at a significantly higher risk of developing Parkinson's disease, according to a new study.

Bees can be trained to recognize human faces, so long as the insects are tricked into thinking that the faces are oddly shaped flowers, new research shows. The insects use the arrangement of facial features to recognize and distinguish one face from another.

Such deforestation has long been driven by farmers eking out a slash-and-burn living or loggers using new roads to cut inroads into pristine forest. But now new data appears to show that, at least for the first five years of the 21st century, big block clearings that reflect industrial deforestation have come to dominate, rather than smaller-scale efforts that leave behind long, narrow swaths of cleared land.
