Users from Northwestern University, working with the Center for Nanoscale Materials EMMD Group at Argonne, have demonstrated the first growth of graphene on a silver substrate. Unique wave-like electron scattering at the edges of the ...
Solar energy has long been used as a clean alternative to fossil fuels such as coal and oil, but it could only be harnessed during the day when the sun's rays were strongest. Now researchers led by Tom Meyer at the Energy Frontier Research ...

Currently, the most efficient methods we have for making fuel – principally, hydrogen – from sunlight and water involve rare and expensive metal catalysts, such as platinum. Humans have for ages taken cues from nature to build ...

PC maker Asus is taking the Windows-Android hybrid concept to another level with a convertible laptop that can switch between the two OSes with the click of an on-screen button. The Asus Transformer Book Duet TD300 comes as a 13.3-inch ...
Gemini Planet Imager's first light image of Beta Pictoris b, a planet orbiting the star Beta Pictoris. The star, Beta Pictoris, is blocked in this image by a mask so its light doesn't interfere with the light of the planet. In addition to ...

Roughly 40 percent of all medications act on cells' G protein-coupled receptors (GPCRs). One of these receptors, beta 2 adrenergic receptor site (B2AR), naturally transforms between two base configurations; knowing the precise location of ...

In a maze of blindingly complex reactions that snap oxygen atoms off cellulose or other bio-sources to create energy-dense fuel, the starting molecule's size has a curious effect. If the oxygen-rich molecule is too short to comfortably ...

One of the most widely known compounds on Earth is carbon dioxide, or CO2. We learn as children that CO2 is a key component of photosynthesis, the process by which plants, algae, and bacteria convert light into energy. This reaction is part ...

In theory, Maxwell's demon can decrease the entropy of a system by opening and closing a door at appropriate times to separate hot and cold gas molecules. But as physicist Leó Szilárd pointed out in 1929, entropy does not ...
