Ancient Skeleton Shows Leprosy May Have Spread to Britain From Scandinavia

An international team, including archaeologists from the University of Southampton, has found evidence suggesting leprosy may have spread to Britain from Scandinavia. The team, led by the University of Leiden examined a 1500 year old male skeleton, excavated at Great Chesterford in Essex, England during the 1950s.

Brain Compass Keeps Flies on Course, Even in the Dark

If you walk into a dark room, you can still find your way to the light switch. That’s because your brain keeps track of landmarks and the direction in which you are moving. Fruit flies also boast an internal compass that works when the lights go out, scientists at the Howard Hughes Medical Institute’s Janelia Research Campus have discovered. Their findings suggest that dissecting how fruit flies navigate through the world could help researchers understand how humans and other mammals perform similar tasks.

Every Bite You Take, Every Move You Make, Astrocytes Will Be Watching You

Chewing, breathing, and other regular bodily functions that we undertake “without thinking” actually do require the involvement of our brain, but the question of how the brain programs such regular functions intrigues scientists. Arlette Kolta, a professor at the University of Montreal’s Faculty of Dentistry, has shown that astrocytes play a key role. Astrocytes are star-shaped glial cells in our brain. Glial cells are not neurons – they play a supporting role.

抱歉了。一来翻译成中文太慢,力不从心;二来全当成普及科技英文吧。我想也许对国内的年轻人学习英文和了解科技动态有所帮助吧。
