In a new paper, experts set forth a framework to increase significantly the number, quality and type of daily tests for detecting SARS-CoV-2, the virus that causes COVID-19, and help reduce inequities for underserved populations that have been disproportionally affected by the disease.

A research team has developed a technique for tracking online foreign misinformation campaigns in real time, which could help mitigate outside interference in the 2020 American election.

New research adds to the growing body of evidence that happiness not only feels good, it is good for your physical health, too.

The discovery of the first active methane seep in Antarctica is providing scientists new understanding of the methane cycle and the role methane found in this region may play in warming the planet.

Scientists looked at the evolution of the virus that causes COVID-19. Their findings could help the design of a new vaccine.

America's oldest citizens say they've been through worse, but many older adults are feeling the stress of COVID-19 and prolonged social distancing measures, according to a new study.

A large fruit-eating bird from Tonga joins the dodo in the lineup of giant island pigeons hunted to extinction.

The hurricanes in the Caribbean became more frequent and their force varied noticeably around the same time that classical Mayan culture in Central America suffered its final demise: We can gain these and other insights by looking at the climate archive.

Adults aged 60 and up have fared better emotionally compared to younger adults (18-39) and middle-aged adults (40-59) amid the COVID-19 pandemic, according to new research.

Concussions can have a compounding effect on children, leading to long-term cognitive, behavioral, and emotional health consequences, according to researchers.

When most people find that their actions have resulted in an undesirable outcome, they tend to rethink their decisions and ask, ''What should I have done differently to avoid this outcome?'' When narcissists face the same situation, however, their refrain is, ''No one could have seen this coming!'' In refusing to acknowledge that they have made a mistake, narcissists fail to learn from those...

Psoriasis afflicts millions of people worldwide, but treatments are limited to small molecules like steroids, which can cause skin thinning and lose their effectiveness over time. Medical researchers have circumvented those problems by using a topical ionic liquid to effectively deliver an RNA-based therapy directly into the skin of mice with psoriasis, which reduced multiple psoriasis-related...

Ancient climate records from Leviathan Cave, located in the southern Great Basin, show that Nevada was even hotter and drier in the past than it is today, and that one 4,000-year period in particular may represent a true, ''worst-case'' scenario picture for the Southwest and the Colorado River Basin -- and the millions of people who rely on its water supply.

Researchers propose mitigating methane production by dairy cattle through breeding. Scientists are targeting reduction of enteric methane in the breeding objectives for dairy cattle to select for animals that use feed more efficiently and thus produce less methane. Because livestock farming contributes 13 percent of global greenhouse gas (GHG) emissions, selective breeding can reduce those...

One member of a larger family of oxygen sensing enzymes could offer a viable target for triple negative breast cancer (TNBC), researchers report in a new study. The findings might offer hope to this subset of patients who have few effective treatment options and often face a poor prognosis.

Summit Lake in remote northwest Nevada is home to the only self-sustaining, robust, lake population of Lahontan Cutthroat Trout, North America's largest freshwater native trout species. Research to understand the reasons why this population continues to thrive, where others have not, will be used to protect the fish and its habitat - as well as to apply the knowledge to help restore other Nevada...

Researchers investigating the ways that plants protect themselves -- from insects to pathogens -- have discovered an ''on-off'' switch that controls plant defensive mechanisms. The switch turns on immune responses minutes after an attack and later sends a deactivation signal to avoid self-inflicted damage. The finding lays the groundwork for improved plant disease resistance and food stability.

A drone prototype that mimics the aerobatic manoeuvres of one of the world's fastest birds, the swift, is being developed by an international team of engineers in the latest example of biologically inspired flight.

The diets of ancient foxes were influenced by humans, and these small carnivores might be tracers of human activity over time.

Antibiotic treatment in early life impedes brain signalling pathways that function in social behavior and pain regulation in mice, a new study has found.

Neurobiologists have found new evidence that specific calcium channel subunits play a crucial role in the development of excitatory and inhibitory synapses.

Researchers have identified new pathways in an RNA-based virus where inhibitors, like medical treatments, unbind. The finding could be beneficial in understanding how these inhibitors react and potentially help develop a new generation of drugs to target viruses with high death rates, like HIV-1, Zika, Ebola and SARS-CoV2, the virus that causes COVID-19.

Researchers used atomic force microscopy to quantitatively evaluate how acidic and sugary drinks affect human tooth enamel at the nanoscale level. This novel approach is useful for measuring mechanical and morphological changes that occur over time during enamel erosion induced by beverages.

Researchers are the first to characterize the ecology and fine-scale habitat use of 'near threatened' whitespotted eagle rays in Florida while also identifying areas of potential interactions between this species and multiple environmental threats. Biotelemetry provided unique insights into this species' occupancy, which is not apparent at the landscape-scale. Prolonged observations showed...
