“#Ultra-thin camera lenses of the future could see the light of day” In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers from Chalmers University of Technology, Sweden, now present a new technology for making the artificial materials known as ‘metasurfaces’, which consist of a multitude of…
“#Physics principle explains order and disorder of swarms” In order to form a swirl, an active particle (in red) must sense the positions and orientations of neighbours within its field of vision and move accordingly. Credit: Tobias Bäuerle Current experiments support the controversial hypothesis that a well-known concept in physics—a critical point—is behind the striking…
“#New topological materials could have multiple electrical properties” It consist of six Dirac cones (located on the dashed circle) that represent the crystalline topological states coexisting with 1D linear spectrum (the X at the middle) that represents the helical metallic channel at the step edge.

“#Warm springs bring early, rapid plant growth, and severe droughts” Credit: CC0 Public Domain A new study shows that the severe impact of the summer drought that hit Europe in 2018 was partly due to the spring heatwave that preceded it, which triggered early and rapid plant growth, depleting soil moisture. With lots of sunshine,…
“#Quantum ‘fifth state of matter’ observed in space for first time” A team of NASA scientists unveiled the first results from Bose-Einstein condensates experiments aboard the International Space Station, where particles can be manipulated free from the constraints of gravity Scientists have observed the fifth state of matter in space for the first time, offering…
“#Could we run out of sand? Scientists adjust how grains are measured” Atolls and islands, like Huvadhoo Atoll, Maldives, could come under increased environmental stress during sea level rise and storms caused by climate change. Understanding how sands protect them is important part of mitigation and management. Credit: Ana Vila-Concejo, The University of Sydney Humans…
“#Crop pathogens ‘remarkably adaptable’” Bananas in Java, Indonesia, infected by the fungal pathogen Fusarium oxysporum f.sp. cubense, causal agent of Fusarium Wilt. Credit: Clare Thatcher Pathogens that attack agricultural crops show remarkable adaptability to new climates and new plant hosts, new research shows. Researchers at the Department of Biosciences, University of Exeter studied the temperature…
“#Viewing dopamine receptors in their native habitat” Cryo-EM structure of the D2 dopamine receptor bound to its G protein. Credit: UT Southwestern Medical Center Dopamine, a chemical that sends messages between different parts of the brain and body, plays a key role in a variety of diseases and behaviors by interacting with receptors on cells….
“#Nature provides roadmap to potential breakthroughs in solar energy technology” Credit: CC0 Public Domain As policymakers increasingly turn toward science in addressing global climate change, one Michigan State University scientist is looking to nature to develop the next generation of solar energy technology. MSU Foundation Professor James McCusker, Department of Chemistry, believes that the future…
“#Scientists apply ‘twistronics’ to light propagation and make a breakthrough discovery” A bilayer of molybdenum trioxide supports highly unusual light propagation along straight paths when the two layers are rotated with respect to each other at the photonic magic angle.
