| Climate change-resistant corals could provide lifeline to battered reefs Posted: 28 May 2021 02:17 PM PDT Corals that withstood a severe bleaching event and were transplanted to a different reef maintained their resilient qualities, according to a new study. |
| A fiery past sheds new light on the future of global climate change Posted: 28 May 2021 12:25 PM PDT Centuries-old smoke particles preserved in the ice reveal a fiery past in the Southern Hemisphere and shed new light on the future impacts of global climate change. |
| Declining biodiversity in wild Amazon fisheries threatens human diet Posted: 28 May 2021 12:25 PM PDT A new study of dozens of wild fish species commonly consumed in the Peruvian Amazon says that people there could suffer major nutritional shortages if ongoing losses in fish biodiversity continue. Furthermore, the increasing use of aquaculture and other substitutes may not compensate. |
| Lessening the cost of strategies to reach the Paris Agreement Posted: 28 May 2021 11:48 AM PDT A team of researchers offer new insight on conversion factors of greenhouse gases into their CO2 equivalent. The publication puts forward the economic benefits of reassessing periodically conversion factors according to scenarios of global warming. |
| Climate change makes West Nile virus outbreaks 'plausible' in UK Posted: 28 May 2021 09:59 AM PDT Climate change will make outbreaks of West Nile virus more likely in the UK within the next 20-30 years, a new study has found. A new scientific model shows the risk of the mosquito-borne pathogen spreading to the country will increase as temperatures rise. |
| Natural gas pipeline density higher overall in more vulnerable US counties Posted: 28 May 2021 08:41 AM PDT An analysis found counties with more socially vulnerable populations had a higher density of natural gas pipelines overall. |
| Scientists develop transparent electrode that boosts solar cell efficiency Posted: 28 May 2021 08:41 AM PDT Developing new ultrathin metal electrodes has allowed researchers to create semitransparent perovskite solar cells that are highly efficient and can be coupled with traditional silicon cells to greatly boost the performance of both devices, said an international team of scientists. The research represents a step toward developing completely transparent solar cells. |
| Video platforms normalize exotic pets Posted: 28 May 2021 08:41 AM PDT Researchers are concerned video sharing platforms could be contributing to the normalization of exotic pets and encouraging the exotic pet trade. |
| Reef-building corals and the microscopic algae within their cells evolve together Posted: 28 May 2021 08:41 AM PDT The microscopic algae that live inside and provide nutrients to their reef-building coral hosts may be evolving in tandem with the corals they inhabit. A new study by biologists reveals that genetic differences within a species of these microalgal symbionts correspond to the coral species they inhabit, a discovery that could have implications for the conservation of these endangered corals. |
| Pollen-sized technology protects bees from deadly insecticides Posted: 28 May 2021 08:40 AM PDT New technology provides beekeepers, consumers and farmers with an antidote for deadly pesticides, which kill wild bees and cause beekeepers to lose around a third of their hives every year on average. |
| Plant flowering in low-nitrogen soils: A mechanism revealed Posted: 28 May 2021 08:40 AM PDT Scientists have described a pathway leading to the accelerated flowering of plants in low-nitrogen soils. These findings could eventually lead to increases in agricultural production. |
| DNA-based material with tunable properties Posted: 28 May 2021 08:40 AM PDT While DNA is often idealized as the 'molecule of life', it is also a highly sophisticated polymer that can be used for next-generation materials. Now scientists have started to harness these properties to craft 'topologically tunable' DNA-based complex fluids and soft materials with potential applications in drug delivery and tissue regeneration. |
| Antarctic hotspot: Fin whales favor the waters around Elephant Island Posted: 28 May 2021 08:40 AM PDT During the era of commercial whaling, fin whales were hunted so intensively that only a small percentage of the population in the Southern Hemisphere survived, and even today, marine biologists know little about the life of the world's second-largest whale. |
| Plastic in Galapagos seawater, beaches and animals Posted: 28 May 2021 05:53 AM PDT Plastic pollution has been found in seawater, on beaches and inside marine animals at the Galapagos Islands. |
| Next-gen electric vehicle batteries: These are the questions we still need to answer Posted: 28 May 2021 05:53 AM PDT The next generation of electric vehicle batteries, with greater range and improved safety, could be emerging in the form of lithium metal, solid-state technology. |
| Bacterium causing deadly rabbit fever remains virulent for months in cold water, researchers report Posted: 27 May 2021 12:54 PM PDT Disease ecologists have published study results showing how they were able to prove, by replicating environmental conditions in the lab, that Francisella tularensis can persist for months in cold water without any nutrients and remain fully virulent. Their results provide a plausible explanation for how the deadly pathogen, which causes rabbit fever, can overwinter in the environment outside of a host. |
| New research deepens mystery about evolution of bees' social behavior Posted: 26 May 2021 10:21 AM PDT A new study has mounted perhaps the most intricate, detailed look ever at the diversity in structure and form of bees, offering new insights in a long-standing debate over how complex social behaviors arose in certain branches of bees' evolutionary tree. The report offers strong evidence that complex social behavior developed just once in pollen-carrying bees, rather than twice or more, separately, in different evolutionary branches -- but researchers say the case is far from closed. |
| Understanding of invisible but mighty particles in Earth's radiation belts Posted: 26 May 2021 06:31 AM PDT Tiny charged electrons and protons which can damage satellites and alter the ozone have revealed some of their mysteries to scientists. |
| eDNA analysis could contribute towards more effective pest control Posted: 26 May 2021 05:49 AM PDT Researchers have successfully detected the environmental DNA of the invasive Argentine ant in surface soil samples, and have demonstrated that eDNA can provide a more accurate understanding of habitat distribution. It is hoped that combining this with pest control plans will contribute towards the successful elimination of destructive, invasive ant species. |
