(Phys.org)—Scientists have used sunlight to turn seawater (H2O) into hydrogen peroxide (H2O2), which can then be used in fuel cells to generate electricity. It is the first photocatalytic method of H2O2 production that ...
(PhysOrg.com) -- An unpiloted, air-breathing spaceplane that takes off from an airport runway, carries up to 30 passengers, and costs less than one-tenth to launch into space compared to a conventional rocket could be ready ...
(PhysOrg.com) -- Most of us, when we take our first science classes, learn that when things cool down, they shrink. (When they heat up, we learn, they usually expand.) However, water seems to be the exception to the rule. ...
(PhysOrg.com) -- With one bottle of drinking water and four hours of sunlight, MIT chemist Dan Nocera claims that he can produce 30 KWh of electricity, which is enough to power an entire household in the developing world. ...
The gas giants have always been a mystery to us. Due their dense and swirling clouds, it is impossible to get a good look inside them and determine their true structure. Given their distance from Earth, it is time-consuming ...

(Phys.org)—In many ways, water behaves very differently than other liquids do, and with important consequences: It's widely thought that water's unusual properties were essential for the development of life on Earth. One ...
A team of researchers affiliated with several institutions in the U.S., including NASA and a pair from Denmark has found that Jupiter's magnetic field is quite different from Earth's. In their paper published in the journal ...
(PhysOrg.com) -- Maybe because it appears as a speck of blood in the sky, the planet Mars was named after the Roman god of war. From the point of view of life as we know it, that's appropriate. The Martian surface is incredibly ...
