More than two years after challenging engineers to develop a new class of vehicle that could achieve 100 miles per gallon or the energy equivalent (mpge), the X PRIZE Foundation on Thursday crowned three winners in its $10-million Progressive Insurance Automotive X PRIZE competition...
More women than men accept the scientific consensus on climate change, new research finds
Properly protecting the world's remaining 3,500 wild tigers from poachers, habitat fragmentation and other threats would cost just 42 percent more than is already spent on tiger conservation—an additional $35 million per year, or $10,000 per cat, according to a new study published September 14 in the journal PLoS Biology ...

New analyses predict health savings from more aggressive reductions in the greenhouse gas emissions causing climate change
Populations of a bumblebee species living on remote Scottish islands have a lack of genetic diversity because of many generations of inbreeding, a situation that could put the region's bumblebees at risk of extinction, according to a new study by scientists from the University of Stirling in Scotland.Penelope Whitehorn, a PhD student, presented the research at last week's annual meeting of the British Ecological Society.The study found that moss carder bumblebees ( Bombus muscorum ) living on nine Hebridean islands off the west coast of Scotland are more susceptible to diseases carried by parasites than healthier populations on the mainland...
This year could be a very bad year for coral reefs, thanks to warm waters as a result of El Nino and climate change. David Biello reports
In 1979, President Jimmy Carter had 32 panels installed atop the White House to capture the sun's heat. Thirty-odd years later, at least one of the panels still works, warming up in the Northeastern sunlight of Boston and sending steam heat out of a spigot on September 8, en route down the east coast from its temporary home at Unity College in Maine...

All the world's power plants, vehicles and factories that presently exist may not emit enough carbon dioxide to cause catastrophic climate change
In the carbon market, a good deal for the environment needs to also be a good deal for the bottom line. Vouching for the environmental credibility isn't easy: Who verifies the verifiers?...
Impact-delivered graphite discovered in Apollo moon rock
The Gulf of Mexico oil spill this year and subsequent cleanup efforts could drive the world's smallest sea horse into extinction, warns the Zoological Society of London and its marine conservation organization Project Seahorse. The tiny dwarf sea horse ( Hippocampus zosterae ), which grows to a maximum length of 2.5 centimeters, can be found only in the ocean waters off the Gulf Coast...
