Luke Skywalker's home in "Star Wars" is the desert planet Tatooine, with twin sunsets because it orbits two stars. So far, only uninhabitable gas-giant planets have been identified circling such binary stars, and many researchers ...

Survey of salmonella species in Staten Island Zoo's snakes

For humans, Salmonella is always bad news. The bacterial pathogen causes paratyphoid fever, gastroenteritis and typhoid. But for snakes, the bacteria aren't always bad news. Certain species of Salmonella are a natural part ...

Yet more opportunities for organic semiconductors

From 'Radio frequency identification' (RFID) tags to OLED displays and photovoltaic cells, organic semiconductors' high potential is widely recognised. A Marie Curie project has set out to bring potential innovation to the ...

Piezoelectric effects for the suppression of material stresses

The generation of electrical charges in response to mechanical deformation is a distinctive feature of piezoelectric materials. This property can be used to avoid mechanical stresses in special materials. A project currently ...

Catalyst redefines rate limitations in ammonia production

Studies by researchers at Tokyo Institute of Technology have developed a catalyst that is so effective at promoting dissociation of the nitrogen bond in ammonia production reactions that it is no longer the step limiting ...

3-D images of tiny objects down to 25 nanometres

Scientists at the Paul Scherrer Institute and ETH Zurich (Switzerland) have created 3D images of tiny objects showing details down to 25 nanometres. In addition to the shape, the scientists determined how particular chemical ...

Flood alerts issued in Kashmir as rivers cross danger mark

Hundreds of Kashmiris in both India and Pakistan moved to higher ground Monday as rain-swollen rivers swamped parts of the disputed Himalayan region placed under an emergency flood alert just six months after some 600 people ...

Citizen scientists map global forests

New maps of global forest cover from the International Institute for Applied System Analysis (IIASA)'s Geo-Wiki team provide a more accurate view of global forests. The maps were published in the journal Remote Sensing of ...
