Spinosaurus was among the largest predators ever to prowl the Earth and one of the most adapted to water, but was it an aquatic denizen of the seas, diving deep to chase down its meals, or a semiaquatic wader that snatched prey from the shallows close to shore? https://phys.org/news/2024-03-analysis-uncovers-major-issues-earlier.html Paleontology & Fossils Wed, 06 Mar 2024 14:00:01 EST news628942673 Greg Rouse, a marine biologist at UC San Diego's Scripps Institution of Oceanography, and other researchers have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica.

Yale researchers have now uncovered one way insect receptors are able to be so selective, an insight they say will help us understand how animals decipher the chemical world and how we might mimic that ability in the future. https://phys.org/news/2024-03-insects-sugars.html Cell & Microbiology Molecular & Computational biology Wed, 06 Mar 2024 13:13:03 EST news628953181 The corn leafhopper Dalbulus maidis has become a serious problem for farmers. This tiny insect is now widely distributed in the Americas, from the south of the United States to the north of Argentina. In Brazil, it uses only corn plants as hosts, and little is known about its survival mechanisms in the absence of these plants. In corn, it causes damage directly by sucking sap from the phloem, the vascular tissue that conducts sugar and other metabolic products downward from the leaves. https://phys.org/news/2024-03-fungus-corn-leafhopper-extremely-pest.html Ecology Agriculture Wed, 06 Mar 2024 12:42:04 EST news628951321 Researchers from the Bhogaraju Group at EMBL Grenoble have gained new insights into how a cancer-relevant family of proteins bind their targets.
