Renewable sources of energy such as wind or photovoltaic are intermittent; production peaks do not necessarily follow the demand peaks. Storing green energy is therefore essential to moving away from fossil fuels. The energy produced by photovoltaic cells and...

Of retiring employees, 12 percent increased their risky drinking at the time of retirement. However, for most people, there was no change in risky level alcohol consumption...
As levels of atmospheric carbon dioxide continue to climb, scientists are looking for new ways of breaking down CO2 molecules to make useful carbon-based fuels, chemicals and other products. Now, a team of Brown University researchers has found a way...
University of Colorado Boulder researchers have developed a new type of malleable, self-healing and fully recyclable "electronic skin" that has applications ranging from robotics and prosthetic development to better biomedical devices.
Electronic skin, known as e-skin, is a thin, translucent...
Three years ago, scientists at the University of Michigan discovered an artificial photosynthesis device made of silicon and gallium nitride (Si/GaN) that harnesses sunlight into carbon-free hydrogen for fuel cells with twice the efficiency and stability of some previous...
Life on Earth arose about 4 billion years ago when the first cells formed within a primordial soup of complex, carbon-rich chemical compounds.
These cells faced a chemical conundrum. They needed particular ions from the soup in order to perform...
Through the analysis of specific fallout particles in the environment, a joint UK-Japan team of scientists has uncovered new insights into the sequence of events that led to the Fukushima nuclear accident in March 2011.
The multi-organisation research, led by...
A method to activate targeted drugs, or smart drugs, only at the selected site of action, an approach that improves the drug's therapeutic effect and minimizes side effects, has been developed in a study led by Georgia State University.
Smart...
Northwestern University researchers have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices -- news to make the ears of Star Trek's Spock perk up.
Using...
Aging usually improves the flavor of cheese, but that's not why some very old cheese discovered in an Egyptian tomb is drawing attention. Instead, it's thought to be the most ancient solid cheese ever found, according to a study...
Scientists have developed a large-scale economical method to extract hydrogen (H2) from oil sands (natural bitumen) and oil fields. This can be used to power hydrogen-powered vehicles, which are already marketed in some countries, as well as to generate...
