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
阅读全文Butterflies and moths collect so much static electricity while in flight, that pollen grains from flowers can be pulled by static electricity across air gaps of several millimeters or centimeters.
阅读全文A small but ferocious predator, the male dragonfish will apparently do anything for love. Or at least to find a mate. A study by researchers at Boston College found that the eyes of the male dragonfish grow larger for mate-seeking purposes, making the dra
阅读全文A new study, led by paleontologists at the Royal Ontario Museum (ROM) is helping resolve the evolution and ecology of Odaraia, a taco-shaped marine animal that lived during the Cambrian period.
阅读全文For decades, insecticide-treated bed nets and indoor insecticide spraying regimens have been important—and widely successful—treatments against mosquitoes that transmit malaria, a dangerous global disease. Yet for a time, these treatments also suppressed
阅读全文In research published in Global Change Biology, investigators have examined DNA within ocean bottom sediment cores to assess changes in living organisms within one of the world's most productive marine ecosystems: the Atacama Trench in the eastern Pacifi
阅读全文Hours after tagging an endangered basking shark off the coast of Ireland in April, researchers captured what they believe is the first ever video of a shark or any large marine animal being struck by a boat.
