It will soon be easy to determine whether a person has an alcohol problem. With a tiny prick of the finger a new method can detect any abuse from the last two weeks. It can also reveal injurious and…

Physiologists estimate that humans have 300 million alveoli in their lungs to get rid of just one kilogram of carbon dioxide per day. At rest, they barely exchange ten liters of breathing air each…

Life on Saturn's icy moon? Unlikely, say University of Illinois researchers, and a new model they have created shows it is possible for a frigid, stiff Enceladus without a shifting interior (such as…

In this fourth installment of our on-going series of interviews with some of the leading thinkers and scientists on the subject of energy, we interview William H. Calvin, PhD. Facing and solving…

Researchers at Rensselaer Polytechnic Institute have developed a new energy storage device that easily could be mistaken for a simple sheet of black paper. The nanoengineered battery is lightweight,…

Do the overall efficiencies of renewable energy sources, such as wind, solar, and geothermal add up in terms of their complete life cycle from materials sourcing, manufacture, running, and…

If you’re among the creatures that produce scads of genetically identical offspring – like microbes, plants or water fleas - you have a good evolutionary strategy, a new study says. These creatures…

James Spivey, professor of chemical engineering at LSU, and Challa Kumar, group leader of nanofabrication at LSU’s Center for Advanced Microstructures and Devices, are working with Clemson University…

Using selective plant breeding and genetic engineering could be used to reduce the incidence of iron deficiency worldwide by improving the quality of dietary iron, conclude authors of a Seminar in…

Computer scientists at the University of Washington have developed software that is incorporated in new technology allowing television audiences to instantaneously see how air flows around speeding…
