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.

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.

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.

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.

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.

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.

Development anomalies recorded for the first time in a rare tiger moth

Posted: 27 May 2021 06:14 AM PDT

The Menetries' tiger moth (Arctia menetriesii) is one of the rarest, most poorly studied Palaearctic moth species. Researchers have now documented the species' biology under laboratory conditions and described its immature stages.

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.

Ultrafast, on-chip PCR could speed diagnosis during current and future pandemics

Posted: 26 May 2021 10:21 AM PDT

Researchers have developed a plasmofluidic chip that can perform PCR in only about 8 minutes, which could speed diagnosis during current and future pandemics.

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.
