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.

New CRISPR tools help contain mosquito disease transmission

Posted: 28 May 2021 11:48 AM PDT

Scientists have developed a genetics toolkit that helps pave the way to a gene drive designed to stop Culex mosquitoes from spreading disease. Much less studied than other genera, Culex mosquitoes spread devastating afflictions stemming from West Nile virus, Japanese encephalitis virus and the pathogen causing avian malaria.

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.

Researchers discover drug that blocks multiple SARS-CoV-2 variants in mice

Posted: 28 May 2021 09:59 AM PDT

A small molecule STING agonist was highly protective against the virus that causes COVID-19 and likely other coronaviruses, researchers have found.

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.

'Good' bacteria show promise for clinical treatment of Crohn's disease, ulcerative colitis

Posted: 28 May 2021 08:40 AM PDT

A new study shows how a novel consortium of bacteria that live in the digestive tracts of healthy individuals can be used to prevent and treat aggressive colitis in humanized mouse models.

How retroviruses become infectious

Posted: 28 May 2021 05:53 AM PDT

Understanding every step in the life cycle of a virus is crucial for identifying potential targets for treatment. Now, scientists were able to show how a virus from the retrovirus family - the same family as HIV - protects its genetic information and becomes infectious. Furthermore, they show an unexpected flexibility of the virus.

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.

The new species of bacteria killing palms in Australia

Posted: 27 May 2021 11:52 AM PDT

While investigating a disease outbreak in a Queensland botanical gardens, researchers discovered a new species of bacteria that causes a fatal disease in palms.

Jebel Sahaba: A succession of violence rather than a prehistoric war

Posted: 27 May 2021 08:25 AM PDT

Since the 1960s, the Jebel Sahaba cemetery (Nile Valley, present-day Sudan) has become the emblem of organised warfare during prehistory. Re-analysis of the data, however, argues for a succession of smaller conflicts. Competition for resources is probably one of the causes of the conflicts witnessed in this cemetery.
