Tech Xplore / Wafer-thin silicon with millions of patterns redirects vibrations along predefined paths
Metamaterials—the term may sound esoteric to the layman. In science and engineering, however, this is an interesting field of research that has developed at a highly dynamic pace, particularly since the 1990s.
Phys.org / Mars's manganese 'bathtub ring' reveals ancient ocean timeline and its potential for life
Past research has indicated Mars's largest northern basin, Utopia Planitia, was once the location of a large body of water, but details surrounding when this body of water may have existed have not been resolved. Researchers ...
Tech Xplore / Dual-mode magnetic elastomer moves on command, vanishes on demand
The rapid expansion of soft robots and smart electronic devices is driving demand for materials that can not only move and adapt, but also complete their missions without leaving behind unwanted traces. As these technologies ...
Phys.org / Tardigrades reveal extreme heat-blocking survival trick while in tun state
Tardigrades, also known as water bears or moss piglets, are tiny eight-legged animals that can survive in extreme environments, where humans and most other animals would die. This resistance to extreme conditions, including ...
Phys.org / Rainfall near 700 mm marks turning point in ecosystem nitrogen retention
In a study published in Nature Geoscience, a research team led by Prof. Liu Lingli from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has identified a mean annual precipitation (MAP) threshold of approximately ...
Phys.org / Nanofiber implant delivers three drugs, doubles survival in glioblastoma mice
Researchers with the University of Cincinnati and Johns Hopkins Medicine developed a potential treatment for brain cancer that uses nanofibers embedded with a combination of drugs that work in concert to target tumors. The ...
Phys.org / A natural chemistry laboratory in protostar shock waves
Life exists because elements combine to form complex organic molecules. Astrochemistry studies this process, trying to understand how nature creates carbon-based molecules critical for life. One source for these types of ...
Medical Xpress / Why some chikungunya virus infections may turn chronic
Chikungunya virus, which is transmitted to people by infected Aedes mosquitoes and characterized by high fever and intense joint swelling and pain, has made a resurgence in many countries around the world in recent years.
Phys.org / Topological states emerge in quantum Hall-superconductor devices with multiple channels
Topological phases are unusual states of matter that give rise to properties protected by a material's overall structure (i.e., "topology"), as opposed to microscopic details. These phases are of great interest for the development ...
Phys.org / A hidden supermassive black hole may be lurking inside the Antennae galaxies
Astronomers may have uncovered a hidden supermassive black hole inside the famous Antennae galaxies NGC 4038/4039, a pair of colliding galaxies best known for their spectacular bursts of star formation. The paper outlining ...
Phys.org / 'Shoot for the moon?' Aim a bit lower, researchers say
How ambitious should you be? Folk wisdom offers conflicting advice: "Shoot for the moon," but also, "Don't let the perfect be the enemy of the good." A new study by researchers at the University of Wyoming, Stanford University ...
Tech Xplore / Tabletop 3D printer cuts semiconductor 3D patterning from days to minutes
Faculty in the Cockrell School of Engineering have developed a rare printer as part of a larger project to speed up production and lower costs of manufacturing semiconductors critical to modern electronics.
