Drought creates increasing challenges for agriculture. As well as affecting crop growth, it also affects interactions with pests. A research team at the University of Göttingen investigated how different levels of drought affect sugar beet's susceptibility to damage caused by the beet leaf miner (Pegomya cunicularia)—a fly whose larvae create visible tunnels inside leaves.
Over the past few decades, scientists have become increasingly interested in developing materials that do not simply withstand mechanical forces but instead respond to them in useful, detectable ways. For example, it is now possible to engineer materials that signal when they are under stress through changes in color or brightness. This growing domain, sometimes called mechanochromic or mechanoresponsive materials science, has found applications in structural sensors and advanced optical technology.
Deploying ocean iron fertilization—a strategy for carbon dioxide capture—in higher latitudes rather than near the equator could reduce environmental impacts while still achieving removal of carbon dioxide from the atmosphere, according to a modeling study published in Nature. The findings offer insight into best practices for maximizing carbon dioxide removal while reducing potential ecological trade-offs typically associated with iron fertilization.
Coho salmon released by recreational anglers are far more likely to survive when handled without a landing net, according to new research. In salmon fisheries where anglers may be required to release salmon that are undersized, wild or not the target species, post-release survival is critical to conservation efforts. The paper is published in the journal Fisheries Research.
The creation of fully artificial organs is a sci-fi dream, and researchers in Japan may have brought it one step closer to reality by developing a new photofabrication technique (i.e., a light-controlled synthetic method) for constructing arteriole-scale tubular hydrogels. Their research is published in the journal Advanced Materials.
The Canadian government is proposing sweeping changes to accelerate industrial development and reduce environmental oversight. These proposed legislative, regulatory and policy reforms could significantly diminish the government's capacity to assess environmental impacts and weaken protections for fish habitats and species at risk.
The chemical synthesis of oligonucleotides (ONs) is central to modern molecular biology, diagnostics and nucleic acid therapeutics. While demand for high-quality ONs is increasing, the conventional synthetic method has long-standing efficiency challenges. Widely adopted P(III)-phosphoramidite-based ON synthesis requires an oxidation step after every nucleotide coupling cycle and uses moisture-sensitive building blocks, adding complexity to the workflow and slowing the process.
Summer can be lovely—until a wasp turns up. Whether they present as an irritating picnic visitor or an uninvited attic guest, common social wasps are as much a part of our summer as festivals, sunscreen and the growing despair of how to entertain children who've forgotten how to be bored.
New research, led by the University of Glasgow reveals that adaptation to warmer waters causes fish to display a range of behavioral and biological differences, including obesity, overeating and lower metabolism.
A lack of data on prisoner characteristics is providing an incomplete picture of who dies in prison and why, which may be contributing to preventable deaths in custody, according to a new report.
