Phys.org / Controlling the rotation direction of light without complex new materials
A new pathway has opened for controlling the rotation direction of light simply by changing how molecules are arranged, without having to synthesize complex new materials. Circularly polarized light is a special form of light ...
Medical Xpress / Why brain imaging struggles to identify psychiatric disorder signatures
For decades, neuroscientists have been trying to determine whether different neuropsychiatric conditions are linked to specific variations in brain structure and neural connections. While past studies identified possible ...
Phys.org / Active supermassive black holes may help form massive planets
A popular myth about black holes is that they act like giant cosmic vacuum cleaners, sucking in everything around them. But Wladimir Lyra's research found a new mechanism around supermassive black holes that is more like ...
Phys.org / Constipation is common in astronauts—blood tests provide new answers
For astronauts in space, constipation is a well-known problem. But why this happens has long been unclear. Now, a new study from the University of Copenhagen in collaboration with NASA provides an idea of what happens in ...
Phys.org / Protein-like nanoparticles sort themselves inside growing crystals, enabling controlled release
The tiny bones in your fingers withstand countless taps and swipes thanks to a precise blend of materials. Flexible collagen fibers form the framework, reinforced by hard calcium phosphate hydroxyapatite crystals. This is ...
Phys.org / Three supermassive black holes discovered in a single galaxy for the first time
An international team of astronomers led by the Max Planck Institute for Extraterrestrial Physics has identified three actively accreting supermassive black holes in the galaxy J0148-4214. Matter is falling into the black ...
Tech Xplore / Hybrid energy system: One roof for electricity, heating and cooling
Photovoltaic panels generate electricity, solar thermal collectors provide heat, while cooling is usually supplied by air conditioning systems that themselves consume electricity. As a result, buildings require different ...
Phys.org / A new category of heat waves is melting western US snowpack faster
Heat waves are not all created equal. While some bring dry heat that rapidly dries out crops, others carry a lot of moisture that can prevent sweat from evaporating off the skin. In new research published in the journal Science ...
Phys.org / Europe's mountain summits are warming—vegetation is responding in surprisingly different ways
Decades of climate change have not left Europe's mountain vegetation unscathed. However, the changes observed do not always match expectations. As a new international study by a research team led by researchers from the University ...
Phys.org / Wheat gene behind Hessian fly resistance cloned after 50-year search
Researchers at the University of Maryland and their collaborators have cloned a gene that makes wheat resistant to feeding by Hessian fly larvae and demonstrated its direct interaction with a protein produced by the insect. ...
Phys.org / Sediments off Brazil's northeast coast reveal sudden changes in heat transport in the Atlantic
According to a new study led by researchers from Brazil and Germany, the main system that transports heat from one end of the Atlantic Ocean to the other may undergo sudden changes in intensity driven by climate change similar ...
Phys.org / Minnesota iron ore could be key to sustainable and lower cost semiconductor
For the first time, researchers at the University of Minnesota Twin Cities have demonstrated that the low-purity iron ore prevalent in Minnesota can be used to create semiconductor-quality iron sulfide, also known as "fool's ...
