Fast-breeder worms & Studious Babies
Two interesting stories from New Scientist:
Mobile phone emissions increase worm fertility
Duncan Graham-Rowe
The safety of mobile phones is under fresh scrutiny following the discovery that their emissions have an unexpected effect on living creatures. The finding throws out the strongest challenge yet to the widely held belief that heating from mobile phone signals is their only potential threat to brain cells.
In lab tests, British scientists have found that microwave emissions typical of mobile phones make a type of worm more fertile. Why this happens is unclear and there’s no suggestion that human fertility could be affected. But the research is important because it reveals, for the first time, that biological effects are possible without any warming of tissues.

Students should be jealous - not only do babies get to doze their days away, but they have also mastered the art of learning in their sleep.
By the time babies are a year old they can recognise a lot of sounds and even simple words. Marie Cheour at the University of Turku in Finland suspected they might progress this fast because they learn language while they sleep as well as when they are awake.
