Nuclear accidents can have devastating consequences for the people and animals living in the vicinity of the damaged power plants, but they also give researchers a unique opportunity to study the effects of radiation on populations that would be impossible to recreate in the lab.
Tim Mousseau, who directs the Chernobyl Research Initiative at the University of South Carolina in Columbia, together with an international team, is studying the long-term ecological and health consequences of the 1986 accident at the Chernobyl nuclear power plant in the Ukraine. Mousseau has been studying Chernobyl since 1998 and his latest work, carried out with colleagues in France and published in Oecologia last month, finds that bird species with orange feathers living in the fallout zone seem to be more susceptible to radiation than their drabber gray and black fellows. They suggest that production of the more colourful pigments consumes antioxidant molecules that would otherwise confer protection against radiation damage, and that this molecular trade-off is shaping bird populations around the former nuclear power plant.

Where some people hear noise, Jeong Ho You hears energy. “Acoustic energy is everywhere,” he says. And with the help of a tiny resonating chamber, he wants to trap some of that energy and convert it into a low-amperage current for use in small electronic devices. You, a mechanical engineer at Southern Methodist University, in Dallas, will be presenting the results of a computer simulation of a resonating chamber design at next month’s Acoustical Society of America meeting in Seattle. He then plans to build a device to see how his idea holds up in the lab. Continue reading Acoustic Energy Harvesters Gaining Volume→
Smartphone owners know all about battery anxiety: Spend too long playing games and the battery icon flashes ”empty” the next time you need to make a call. For drivers of electric cars, the problem is more serious: They can’t just walk over with a 20-liter jug of electricity from the nearest charging station, and even if they do manage to glide into a station on their last electrons, it could take hours to top off a car battery. Continue reading EV Battery Swapping’s First Real Test→
MADRID — In Spain, the government’s overall spending on research is set to wither by about 8% this year, according to an analysis released last fall by the Confederation of Spanish Scientific Societies. Given the climate of budget cuts, it’s perhaps no surprise that scientists there are turning to the public for funding. Continue reading Facing budget cuts, Spain launches funding foundation→
