New 'interspecies communication' strategy between gut bacteria and mammalian hosts uncovered
Bacteria in the gut do far more than help digest food in the stomachs of their hosts, they can also tell the genes in their mammalian hosts what to do.

Thermally-painted metasurfaces yield perfect light absorbers for high-tech applications
Researchers have discovered that the ancient technique of heating metal to create vibrant colors creates a nanostructured surface that acts as a perfect light absorber. Perfect light absorbers—materials that absorb more ...
Microalgae as natural detector of environmental safety
An international group of toxicologists, including experts from the Far Eastern Federal University (FEFU), report that unicellular microalgae, the most common microorganisms on Earth and an important part of the food chain ...
The global impact of coal power
Coal-fired power plants produce more than just carbon dioxide, which contributes to global warming. Coal burning also releases particulate matter, sulphur dioxide, nitrogen oxide and mercury—thus damaging the health of ...
Scientists develop tungsten-based hydrogen detectors
A team of physicists from Immanuel Kant Baltic Federal University together with their colleagues from National Research Nuclear University MEPhI (NRNU MEPhI) has developed a tungsten oxide-based detector of hydrogen in gas ...
Theories describe dynamically disordered solid materials
Theoretical physicists at Linköping University have developed a computational method to calculate the transition from one phase to another in dynamically disordered solid materials. This is a class of materials that can ...
Scientists take X-ray aim in effort to discover new fuel catalyst
For many years, scientists have been looking for an effective and efficient way to turn water into energy-storing fuels using solar- and wind-powered electricity, likely by splitting water into hydrogen and oxygen. To do ...
Green water-purification system works without heavy metals or corrosive chemicals
Scientists at the Institute of Process Engineering (IPE) at the Chinese Academy of Sciences in Beijing and Yangzhou University (YZU) in Jiangsu have developed an effective and energy-efficient technique for purifying water ...
Untangling a strange phenomenon that both helps and hurts lithium-ion battery performance
The lithium-ion batteries that power electric vehicles and phones charge and discharge by ferrying lithium ions back and forth between two electrodes, an anode and a cathode. The more lithium ions the electrodes are able ...
Controlling charge flow by managing electron holes
Much remains to be learned about how charge moves along the molecules that make up the layers of materials in solar cells. These details have remained hidden because of the challenges of direct, real-time observation of motion ...
