Two new drug compounds – one of which has already proven useful in a mouse model of multiple sclerosis – appear to be effective in treating endometriosis, a disorder that, like MS, is driven by estrogen and inflammation, scientists report in Science Translational Medicine.
It isn’t that women don’t want to work long hours or can’t compete in highly selective fields, and it isn’t that they are less analytical than men, researchers report in a study of gender gaps in academia. It appears instead that women are underrepresented in academic fields whose practitioners put a lot of emphasis on the importance of being brilliant – a quality many people assume women lack.
A new study suggests that dogs may have first successfully migrated to the Americas only about 10,000 years ago, thousands of years after the first human migrants crossed a land bridge from Siberia to North America.
A new study finds that smokers and the obese ring up substantially higher annual health care costs than their nonsmoking, non-obese peers. The added costs are highest among women, non-Hispanic whites and older adults, the study reports.
An international effort involving more than 100 researchers, nine supercomputers and about 400 years of CPU time has yielded the most reliable avian tree of life yet produced, researchers report in the journal Science. The tree reflects the evolutionary relationships of 48 species of birds.
The house mouse, stickleback fish and honey bee appear to have little in common, but at the genetic level these creatures respond in strikingly similar ways to danger, researchers report. When any of these animals confronts an intruder, the researchers found, many of the same genes and brain gene networks gear up or down in response.
