Phys.org / Defect detection automated in diamond, other advanced semiconductors
Materials scientists at Rice University have developed a new workflow methodology for measuring microscopic defects in diamond and other advanced semiconductor materials. By making it easier to spot flaws that can undermine ...
Medical Xpress / Opposing protein pathways steer skin stem cells toward renewal or repair
Two proteins with opposing functions orchestrate the development and maintenance of healthy skin, Stanford Medicine researchers have found. Modulating their activity with topical drugs could reduce inflammation, aid wound ...
Phys.org / AI reads 3D tooth microwear to reconstruct diets of early human ancestors
The study of dental microwear allows the analysis of the microscopic marks that foods leave on the surface of tooth enamel during mastication. In paleoanthropology, this methodology helps reconstruct the diet of fossil primates ...
Phys.org / Why female guppies prefer rare males and how this might shape evolution
When it comes to choosing a partner, some species prefer males that stand out from the crowd. Evolutionary biologists call the resulting process negative frequency-dependent selection. It means that a male has a huge mating ...
Medical Xpress / First 3D views of human cone opsins reveal how daylight vision reacts so fast
The retina of the human eye contains 6–7 million cone cells. These cells contain light-sensitive proteins known as cone opsins. They enable us to perceive our surroundings in detail in daylight. They allow us to see the world ...
Phys.org / Antibiotics trigger bacterial teamwork, boosting survival through shared proteins
When bacteria are under antibiotic attack, it is not "every man for himself." Researchers at Baylor College of Medicine and colleagues from collaborating institutions have discovered that bacterial populations work as a team ...
Phys.org / Sponges may cut methylmercury contamination in marine food webs by more than 50%
Marine sponges may play an important, previously underestimated role in reducing methylmercury contamination in marine food webs. In a new modeling study, researchers at Helmholtz-Zentrum Hereon showed that sponges can significantly ...
Phys.org / Trios of quantum particles form checkerboard layouts when particle density hits sweet spot
Trions form when three particles, like quarks or electrons, come together. This formation occurs in quantum particles in nuclear physics, semiconductors and magnets, and understanding its behavior can be challenging. Rice ...
Dialog / Miniature satellite tags reveal diving behavior of juvenile sea turtles
Until recently, researchers were unable to conduct satellite-tracking studies on juvenile turtles because of their small body sizes and immediate dispersal into the ocean, leaving this period of their lives enigmatic and ...
Tech Xplore / Generative AI designs DNA origami to match user-drawn shapes automatically
A joint research team has developed an automated design technology that enables the creation of DNA origami structures that exactly match user-drawn shapes using generative AI. The generative design model, "Generative SNUPI," ...
Phys.org / Interlayer self-doping could unlock room-temperature multiferroics in atom-thin materials
Multiferroics are materials that exhibit more than one prominent "ferroic" property, such as ferromagnetism and ferroelectricity. One of their most advantageous features is that they allow engineers to control their magnetic ...
Phys.org / Artificial DNA tiles could deliver drugs and monitor neurons non-disruptively
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
