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 / 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 / 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 / Discovery reveals how acetylation controls key enzyme linked to cancer growth
Researchers from the University of Seville have participated in research to identify the molecular details of the regulation of an enzyme essential for sugar metabolism and closely linked to cell proliferation and growth: ...
Phys.org / Halley's Comet wrongly named: 11th-century English monk predates British astronomer
The British astronomer and mathematician Edmond Halley was not, after all, the first to understand the cycle of the comet that now bears his name. This is shown by research conducted by, among others, Professor Simon Portegies ...
Phys.org / Harnessing nanoscale magnetic spins to overcome the limits of conventional electronics
Researchers at Kyushu University have shown that careful engineering of materials interfaces can unlock new applications for nanoscale magnetic spins, overcoming the limits of conventional electronics. Their findings, published ...
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 / 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 / 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 / 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 / 40 years of tree-tracking records reveal how global change is impacting Amazon and Andean Forest diversity
New research published in Nature Ecology and Evolution reveals significant recent shifts in tree diversity among the tropical forests of the Andes and Amazon, driven by global change.
