Phys.org / 2D material offers a solution to long-standing obstacle in diamond-based circuits
Beyond their sparkle, diamonds have hidden talents. They shed heat better than any material, tolerate extreme temperatures and radiation, and handle high voltages while wasting almost no electricity—ideal traits for compact, ...
Phys.org / Refined radiocarbon dating provides clearer timeline of human activity along Cantabrian coast 18,000 years ago
A new study refines radiocarbon dating of marine remains and significantly improves the precision with which the human past of the Magdalenian period in the Cantabrian region of Spain can be reconstructed, a key phase of ...
Phys.org / Biologists and engineers follow goopy clues to plant-wilting bacteria
Slippery, drippy goop makes Ralstonia bacteria devastating killers of plants, causing rapid wilting in tomato, potato, and a wide range of other crops, according to new research. The work, published Jan. 22 in Proceedings ...
Phys.org / Climate change can alter flower nectar quality and supply, threatening monarch butterfly migration
Monarch butterflies have always been remarkably resilient. Every fall, these delicate orange-and-black travelers set out on a journey so improbable it borders on myth, flying some three thousand kilometers from Canadian fields ...
Phys.org / Whales may divide resources to co-exist under pressures from climate change
The North Atlantic Ocean is warming up. Higher temperatures and increased human activity in the region can trigger abrupt changes in marine ecosystems, for example, how species are distributed and what they eat.
Phys.org / Glassy dynamics model predicts lipid exchange rates across cell membranes
Biological processes that govern our lives are many, intertwined, and often difficult to understand. They involve countless interactions happening at once—molecules recognizing each other, signals being transmitted, and ...
Phys.org / Multiwavelength variability reveals dust structure in quasars
A research team has investigated quasar variability by tracking optical to mid-infrared (MIR) wavelengths of variability information. This multiband joint analysis provides an opportunity to probe the dust structure in the ...
Phys.org / The art of custom-intercalating 42 metals into layered titanates
A research team affiliated with UNIST has reported a novel synthesis strategy that enables the direct intercalation of a wide range of metal cations into the interlayer spaces of layered titanate (LT) structures. This approach ...
Phys.org / Light-controlled switches offer precise regulation of ion channels in living cells
Researchers at Leipzig University and TU Dresden have succeeded in developing biological switches that can selectively turn ion channels on and off using light pulses. Initial applications show that it is possible, for example, ...
Phys.org / Florida reefs offer multimillion-dollar flood protection—if they survive
It's no secret that Florida's iconic coral reefs are in trouble. Repeated body blows from hurricanes, pollution, disease, climate change—and a near-knockout punch from a 2023 marine heat wave—has effectively wiped several ...
Phys.org / Discovery of PITTs shows platelets can switch from clotting to driving vessel inflammation
A team from Würzburg has fundamentally changed our understanding of platelet biology. The researchers demonstrate that the surface protein integrin αIIbβ3 is not only a key molecule in blood clotting, but can also act ...
Phys.org / Four-eyed Cambrian fish fossils hint at origins of vertebrate pineal complex
New fossil evidence from China suggests that some of our vertebrate ancestors had four eyes. The study, published in Nature, takes a closer look at a structure found in multiple 518 million-year-old fossils, which appears ...
