(Phys.org) -- A UK company has developed an electronic nose that the company says can make a real difference, as a fast-acting device for detecting harmful substances in the environment. Peratech claims its electronic nose can pick up the presence of volatile organic compounds (VOCs) quickly and that its fast-acting ...

A basic tenet underpinning scientists' understanding of extinction is that more abundant species persist longer than their less abundant counterparts. A new study reveals a much more complex relationship. A team of scientists analyzed more than 46,000 fossils from 52 sites and found that greater numbers did indeed help clam-like ...

Three football helmets received the highest mark: a 5-star rating: the Riddell Revolution Speed, the Rawlings Quantum Plus and Riddell 360.

A scientist provides an example of a nanotechnology-related safety and ethics problem that is unfolding right now.

A recent paper by Kathleen Eggleson, a research scientist in the Center for Nano Science and Technology (NDnano) at the University of Notre Dame, provides an example of a nanotechnology-related safety and ethics problem that is unfolding right now.

RedOrbit.com Meteorologist Joshua KellyNow that the 2012 severe weather season is upon us it is time to look at a few things that you can do to help prepare yourself and family.First, the National Weather Service this week has started working with new alarm systems that are going to provide ...

Scientists turned to squeezed polymers and free radicals in a search for new energy sources. They found both promise and problems. The researchers demonstrated that radicals from compressed polymers generate significant amounts of energy that can power chemical reactions in water. They also discovered that a silicone polymer commonly used ...

A polymer is a mesh of chains, which slowly break over time due to the pressure from ordinary wear and tear. When a polymer is squeezed, the pressure breaks chemical bonds and produces free radicals: ions with unpaired electrons, full of untapped energy. These molecules are responsible for aging, DNA ...

Using high-precision microscopy and X-ray scattering techniques, University of Oregon researchers have gained eye-opening insights into the process of applying green chemistry to nanotechnology that results in high yields, improves efficiency and dramatically reduces waste and potential negative exposure to human health or the environment.
