Their modification can increase solar cell efficiency by more than 30 percent. Researchers from North Carolina State University and the Chinese Academy of Sciences have found an easy way to modify the molecular structure of a polymer commonly used in solar cells. Their modification can increase solar cell efficiency by more than 30 percent. Polymer-based

Though considered a promising large-scale energy storage device, the vanadium redox battery’s use has been limited by its inability to work well in a wide range of temperatures and its high cost. But new research indicates that modifying the battery’s electrolyte solution significantly improves its performance. So much so that the upgraded battery could improve

A new study from the Swedish medical university Karolinska Institutet presents a new technique that makes drug testing possible through exhaled air for the first time. By examining people who had received emergency care for an amphetamine overdose, the researchers found that in all cases there were traces of amphetamine and metamphetamine in the exhaled

“We find that combining the hormones as a single molecule dramatically enhanced their efficacy and their safety” Scientists at Indiana University and international collaborators have found a way to link two hormones into a single molecule, producing a more effective therapy with fewer side effects for potential use as treatment for obesity and related medical

Solar-powered water splitting is a promising means of generating clean and storable energy. A novel catalyst based on semiconductor nanoparticles has now been shown to facilitate all the reactions needed for “artificial photosynthesis”. In the light of global climate change, there is an urgent need to develop efficient ways of obtaining and storing power from

Computational method helps scientists examine microbes at a larger, more comprehensive scale than previously possible During the Zika virus outbreak of 2015–16, public health officials scrambled to contain the epidemic and curb the pathogen’s devastating effects on pregnant women. At the same time, scientists around the globe tried to understand the genetics of this mysterious

Microsoft has allowed the public to get their hands on its new hands-free games controller for the first time. The controller uses a microphone combined with visual and infrared cameras to control the onscreen action.

Scientists report that chemicals that are not controlled by a United Nations treaty designed to protect the Ozone Layer are contributing to ozone depletion. In the new study, published today in Nature Geoscience, the scientists also report the atmospheric abundance of one of these ‘very short-lived substances’ (VSLS) is growing rapidly. Study lead author Dr

Technology captures water evaporating from cooling towers; prototype to be installed on MIT’s Central Utility Plant. A new system devised by MIT engineers could provide a low-cost source of drinking water for parched cities around the world while also cutting power plant operating costs. About 39 percent of all the fresh water withdrawn from rivers,

Mass.-General-developed technique could extend preservation times for blood cells, tissues and organs Investigators from the Massachusetts General Hospital Center for Engineering in Medicine (MGH-CEM) have developed a simple method to maintain water and water-based solutions in a liquid state at temperatures far below the usual “freezing point” for greatly extended periods of time. While they currently have
