Flying, flapping robots could soon get an upgrade, thanks to new research that reveals the deceptively simple mechanism used by bats, birds and bugs to turn in flight.

Study of neighborhoods points to modifiable factors, not race, in cancer disparities

While cities have shown considerable racial disparities in cancer survival, those racial disparities virtually disappear among smaller populations, such as neighborhoods within that city. The finding comes from a new analysis published in the May 15, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society. The study examined breast and prostate cancer survival rates at different geographic levels, and the results suggest that there are significant societal factors at the root of cancer-related racial disparities. Previous research has shown that considerable health disparities exist relating to race, ethnicity, geographic location, and other factors. While researchers have been striving to understand the causes of such disparities in survival from some cancers, including cancers of the breast and prostate, the potential roles of innate factors, such as genetic differences, versus modifiable factors, such as socioeconomic differences, remain unclear.

Obama's energy czar visits Oakland program
April 12, 2009 11:09 AM - Josh Richman, Oakland Tribune

President Barack Obama's energy and climate-change czar seemed to like what she saw at a green-jobs training program Friday in West Oakland. "It is so impressive what you all are doing," Carol Browner said while visiting the Cypress Mandela Training Center on Poplar Street, noting this was her first solo field trip in her capacity as head of the White House Office of Energy and Climate Change"

Climate change 'own goal': Laws to combat acid rain are DRIVING Arctic warming, claims Nasa
April 12, 2009 11:00 AM - Cher Thornhill, Daily Mail

It is widely recognised that humans are their own worst enemies when it comes to global warming. But the latest research from Nasa suggests laws created to preserve the environment are causing much of the damage. Legislation to improve air quality and cut acid rain has accounted for a shocking half of Arctic warming over the past three decades, the space agency reports.

Seals and robotic subs monitor Antarctic climate change

Elephant seals equipped with electronic tags and robotic mini submarines using sonar were just two projects during the International Polar Year (IPY) that aimed to investigate the effects of global warming in polar regions.

Obama climate adviser open to geo-engineering to tackle global warming

The global warming situation has become so dire that Barack Obama's chief scientific adviser has raised with the president the possibility of massive-scale technological fixes to alter the climate known as 'geo-engineering'. John Holdren, who is a member of the president's cabinet, said today the drastic measures should not be "off the table" in discussions on how best to tackle climate change. While his office insisted that he was not proposing a dramatic switch in policy, Holdren said geo-engineering could not be ruled out.

Solar-powered cooker wins climate prize
