As lithium-ion batteries continue to decrease in price, they are quickly replacing the lead-acid batteries traditionally used in cars and other vehicles. This is creating a sudden abundance of used lead-acid batteries, which would be harmful to the environment and people if not recycled properly. To help deal with this... Read more

Native speakers often dominate the discussion in multilingual online meetings, but adding an automated participant that periodically interrupts the conversation can help non-native speakers get a word in edgewise, according to new research at Cornell.... Read more

Rats are commonly known as pests and spreaders of disease and many people's worst nightmare. Yet they are very clever creatures, and can be trained just as well as dogs. The Belgian aid organization APOPO trains African hamster rats to search for earthquake victims under rubble, using a backpack on... Read more

Physics researchers at Lund University in Sweden recently succeeded in constructing small solar radiation-collecting antennas—nanowires—using three different materials that are a better match for the solar spectrum compared with today's silicon solar cells. As the nanowires are light and require little material per unit of area, they are now to... Read more

A team of researchers, led by Trisha L. Andrew, professor of chemistry and chemical engineering at the University of Massachusetts Amherst, recently announced that they have synthesized a new material that solves one of the most difficult problems in the quest to create wearable, unobtrusive sensitive sensors: the problem of...

Since the ancient Greeks, humankind has known that if you bring two things into contact, a small amount of electricity is created. One example is that we can rub a balloon with our hair and generate enough electricity to stick it to the ceiling.... Read more

A solar distillation device can purify brine from reverse osmosis plants with over 10 percent salinity, as well as water taken directly from the Red Sea. The technology offers double the freshwater production rate of existing salt-rejection solar stills.... Read more

For many avid outdoorspeople, summertime and camping go hand in hand. But as climate change continues to drive summer temperatures higher, outdoor recreation could become less relaxing—and cooling technologies like fans and portable air conditioners require electricity that is seldom available at the average campsite....
