Chemists have reported a new form of hydrogen production that is 30 times faster than the current state-of-the-art method. This is a major step forward in the production of hydrogen from water, which could lead to a new era of cheap, clean and renewable energy.
In a statement this week, Yahoo said that, in 2007, the government amended a law to demand user information from online services, prompting a challenge during the George W. Bush administration. The government called for the huge fine in 2008 if Yahoo didn't go along with an expansion of U.S. surveillance by surrendering online information, a step the company regarded as unconstitutional.
Cuba's health ministry said today that it is sending more than 160 health workers to help stop the raging Ebola outbreak in Sierra Leone, providing a much-needed injection of medical expertise in a country where health workers are in short supply. World Health Organization chief Margaret Chan said the agency was extremely grateful for the help.

Anyone who has seen pictures or models of the human brain is aware that the outside layer, or cortex, of the brain is folded in an intricate pattern. Now, a new study suggests that schizophrenia is associated with reductions in the complexity of the cortical folding pattern that may reflect deficits in the structural connections between brain regions.
Archaeologists slowly digging through a huge 2,300-year-old tomb in northern Greece have uncovered two life-sized marble female statues flanking the entrance to one of three underground chambers.
Researchers have created the world’s largest DNA origami, which are nanoscale constructions with applications ranging from biomedical research to nanoelectronics. These origami can be customized for use in everything from studying cell behavior to creating templates for the nanofabrication of electronic components.
Researchers have shown the use of sound to communicate with an artificial atom. They can thereby demonstrate phenomena from quantum physics with sound taking on the role of light.
There is hardly a spot on the planet where manmade noise doesn’t mix with— or intrude on, from another perspective— the sounds of the natural world. Eventually, one professor says, the only way people may be able to hear nature on its own terms is through an artificial digital world, much like “Star Trek.”
He's traveled to the sites of worrisome outbreaks of SARS, bird flu, MERS. But the Ebola outbreak that's spiraled out of control in West Africa presents new challenges for even a veteran infectious disease doctor— starting with how to stay safe.
The Nuclear Regulatory Commission has rejected a senior federal expert's recommendation to shut down California's last operating nuclear power plant until the agency can determine whether its twin reactors can withstand powerful shaking from nearby earthquake faults. In a decision, the agency concluded there is no immediate or significant safety concern at the Diablo Canyon plant.
Astronauts are studying how fires burn in microgravity and how to put them out. It's a basic safety issue: if a fire ever breaks out onboard a spacecraft, astronauts need to be able to control it.
Scientists have successfully reset human pluripotent stem cells to the earliest developmental state – equivalent to cells found in an embryo before it implants in the womb (seven to nine days old). These pristine stem cells may mark the true starting point for human development but have been impossible to replicate in the lab until now.
An interactive online tool allows users to calculate the value of an ecosystem, and lets them determine how altering a habitat can affect its economic, social and environmental worth.
New research findings point toward future approaches to fighting bacterial biofilms that foul everything from implantable medical devices to industrial pipes and boat propellers.
