Silver and white cars are cooler, says study

(PhysOrg.com) -- From an environment standpoint, silver and white cars are cool; black cars are not. Researchers at the Berkeley Lab Environmental Energy Technologies Division (EETD) say that the color of your car affects ...

'Artificial leaf' makes fuel from sunlight (w/ video)

Researchers led by MIT professor Daniel Nocera have produced something they’re calling an “artificial leaf”: Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that ...

Lessons to be learned from nature in photosynthesis

Photosynthesis is one of nature's finest miracles. Through the photosynthetic process, green plants absorb sunlight in their leaves and convert the photonic energy into chemical energy that is stored as sugars in the plants' ...

Alien world is blacker than coal

(PhysOrg.com) -- Astronomers have discovered the darkest known exoplanet - a distant, Jupiter-sized gas giant known as TrES-2b. Their measurements show that TrES-2b reflects less than one percent of the sunlight falling on ...

Bring in the (nano) noise

(PhysOrg.com) -- At the forefront of nanotechnology, researchers design miniature machines to do big jobs, from treating diseases to harnessing sunlight for energy. But as they push the limits of this technology, devices ...

Teaching algae to make fuel

Many kinds of algae and cyanobacteria, common water-dwelling microorganisms, are capable of using energy from sunlight to split water molecules and release hydrogen, which holds promise as a clean and carbon-free fuel for ...

City lights make air pollution worse

(PhysOrg.com) -- A new study by scientists in Los Angeles, California has found that bright city lights makes air pollution worse because the glare of the lights interferes with chemical reactions that clean the air of pollution ...

Fine-tuning photosynthesis

A new analysis by MIT researchers could make it possible to design more efficient artificial systems that mimic the way plants harvest the energy of sunlight through photosynthesis.
