A billion holes can make a battery
Researchers have invented a single tiny structure that includes all the components of a battery that they say could bring about the ultimate miniaturization of energy storage components.
Upgrading infrastructure could reduce flood damage
The severe flooding that devastated a wide swath of Colorado last year might have been less destructive if the bridges, roads and other infrastructure had been upgraded or modernized, according to a new study.
Taxi GPS data helps researchers study Hurricane Sandy''s effect on NYC traffic
The largest Atlantic hurricane on record, Hurricane Sandy, offered a chance for researchers to try out a new computational method they developed that promises to help municipalities quantify the resilience of their transportation systems to extreme events using only GPS data from taxis.
New solar power material converts 90 percent of captured light into heat
A multidisciplinary engineering team developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive...
New feather findings get scientists in a flap
Scientists have revealed that feather shafts are made of a multi-layered fibrous composite material, much like carbon fiber, which allows the feather to bend and twist to cope with the stresses of flight. Since their appearance over 150 million years ago, feather shafts (rachises) have evolved to be...
Facetless crystals that mimic starfish shells could advance 3-D-printing pills
In a design that mimics a hard-to-duplicate texture of starfish shells, engineers have made rounded crystals that have no facets.
Impact of offshore wind farms on marine species
Offshore wind power is a valuable source of renewable energy that can help reduce carbon emissions. Technological advances are allowing higher capacity turbines to be installed in deeper water, but there is still much unknown about the effects on the environment. Scientists have now reviewed the pot...
Bias in transportation system design exposed
America''s streets are designed and evaluated with an inherent bias toward the needs of motor vehicles, ignoring those of bicyclists, pedestrians, and public transit users, according to a new study.
Power of thorium for improved nuclear design explored by scientists
The development of a radical new type of nuclear power station that is safer, more cost-effective, compact, quicker and less disruptive to build than any previously constructed is underway.
