Fabricating 3D Photonic Crystals
(PhysOrg.com) -- “In photonic crystals, the ability to control the structure of a material in full three dimensional space, allows you to control the way that light flows through it,” John Rogers tells PhysOrg.com. “This ...

Hatchery fish mask the decline of wild salmon populations
Scientists have found that only about ten percent of the fall-run Chinook salmon spawning in California's Mokelumne River are naturally produced wild salmon. A massive influx of hatchery-raised fish that return to spawn in ...

UV lithography: Taking extreme measures
(PhysOrg.com) -- Sometime soon, microchip fabricators will take the next major step in the relentless reduction of feature size, from the current minimum of 22 nm down to 10 nm and perhaps even smaller. Getting ...

Researchers identify brain cells responsible for keeping us awake
Bright light arouses us. Bright light makes it easier to stay awake. Very bright light not only arouses us but is known to have antidepressant effects. Conversely, dark rooms can make us sleepy. It's the reason some people ...

Light dependency underlies beneficial jetlag in racehorses
A new study has shown that racehorses are extremely sensitive to changes in daily light and, contrary to humans, can adapt very quickly to sudden shifts in the 24-hour light-dark cycle, such as those resulting from a transmeridian ...

Deep oceans can mask global warming for decade-long periods
The planet's deep oceans at times may absorb enough heat to flatten the rate of global warming for periods of as long as a decade even in the midst of longer-term warming, according to a new analysis led by the National Center ...

Aerosols affect climate more than satellite estimates predict
Aerosol particles, including soot and sulfur dioxide from burning fossil fuels, essentially mask the effects of greenhouse gases and are at the heart of the biggest uncertainty in climate change prediction. New research from ...
