Trees in the Brazilian Atlantic Forest are migrating in search of more favorable temperatures, with species in mountain forests moving uphill to escape rising heat caused by climate change, a new study reveals.
阅读全文Scientists have succeeded in pinpointing the neurons within a female fruit fly's brain that respond to signals from the male during mating.
阅读全文Every plant, animal, and person is a rich microcosm of tiny, specialized cells. These cells are worlds unto themselves, each with their own unique parts and processes that elude the naked eye.
阅读全文Two scientists at the University of California, Los Angeles, have developed a way to calculate the approximate speed of disease spread between distant places via ocean travel hundreds of years ago.
阅读全文Ignacio A. Lazagabaster, a Ramón y Cajal researcher at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), is part of the international team that has published a study of the biogeographic context of human evolution in the East Africa
阅读全文A team of marine biologists and ecotoxicologists affiliated with several institutions in Brazil has found cocaine in muscle and liver samples collected from Brazilian Sharpnose sharks harvested off the coast of Rio de Janeiro. Their study, published in th
阅读全文How many dung beetles are there in East Africa? That question inspired a research project more than 20 years ago when Frank Krell was a research entomologist with the Natural History Museum London. Throughout a three-year-long project along with his wife,
阅读全文Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock—corn stover, energy sorghum, miscanthus or switchgrass—performed best in a
阅读全文The identification of a key gene in monotremes has increased our understanding of why the stomachs of platypuses and echidnas are atypically small, non-acidic, and, in the instance of platypuses, lack a pyloric sphincter.
阅读全文Researchers at the University of Cambridge have demonstrated that the plant hormone gibberellin (GA) is essential for the formation and maturation of nitrogen-fixing root nodules in legumes and can also increase nodule size. They identified the specific t
阅读全文Drylands cover about 42% of the Earth's land surface and are increasingly threatened by human land-use pressures like agriculture, alternative energy sources, overgrazing and climate change. Up to a third of the global human population living in drylands
阅读全文The behavior of the cells that make up our blood vessels is crucial to our well-being. Conditions such as inflammation, oxygen deprivation and viral infection can stress these cells and disrupt the formation of new, often pathological, blood vessels. Now
