A study conducted at the University of São Paulo suggests that tissues specializing in saliva production and secretion serve as reservoirs for SARS-CoV-2, magnifying its infectious potential.

The expected decline in the number of landfills across the United States coupled with bans on disposing large amounts of organic waste in landfills that have been enacted in multiple states has prompted researchers at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) to examine other ways to grapple with the issue of food waste disposal.

Higher levels of plaque in people with HIV can be partly traced to the nontraditional risk factors of increased arterial inflammation and immune system activation. Researchers uncovered two key biomarkers of plaque that will be studied in the next phase of the global REPRIEVE trial to predict coronary plaque progression and major cardiovascular events, such as heart attacks and stroke, and the potential effects of statins.

Cardiovascular drugs do not affect COVID-19 outcomes--such as disease severity, hospitalizations, or deaths--according to an analysis of all relevant studies published as of November 2020. The findings are published in the British Journal of Clinical Pharmacology.

Despite being relatively new in China, community-led seedbanks are a valuable resource in conserving agricultural biodiversity. For the first time, researchers have provided a comprehensive summary of the services performed by 27 seedbanks across the country

Many people who undergo trauma take a long time to truly heal from the post-traumatic stress disorder, which manifests as flashbacks and nightmares to the traumatic incident. Medical researchers have been trying different therapeutic approaches to reduce these manifestations. A group of Japanese medical researchers report that trihexyphenidyl, a central anticholinergic drug, might just be the answer, in their new study published in Brain and Behavior.

NYU Abu Dhabi (NYUAD) researchers uncovered a code that sets the genome of the liver to account for the remarkable ability for this organ to regenerate. This finding offers new insight into how the specific genes that promote regeneration can be activated when part of the liver is removed. These findings have the potential to inform the development of a new form of regenerative medicine that could help non-regenerative organs regrow in mice and humans.

For the first time, University of Basel researchers have equipped an ultrathin semiconductor with superconducting contacts. These extremely thin materials with novel electronic and optical properties could pave the way for previously unimagined applications. Combined with superconductors, they are expected to give rise to new quantum phenomena and find use in quantum technology.

If plants are flooded, they lack oxygen and their cells over-acidify. A sensor protein detects this and triggers a stress response. Researchers have now presented details about this topic in the journal Current Biology.

Until now, fisheries have set catch levels a year in advance. Long-term influences such as changes in water temperatures are not taken into account. In an international project, researchers from Helmholtz-Zentrum Hereon have now developed a computational model that can estimate the future of cod a full ten years in advance - taking into both account fishing and climate. The fishing industry has a completely new planning tool at its disposal. The study was published in Nature Communications Earth and Environment.

Researchers from HSE University and Max Planck Institute for Human Cognitive and Brain Sciences have discovered how the theta rhythm of the brain and the gender differences in attitudes to risk are linked. In an article published in the journal Frontiers in Neuroscience, the researchers addressed which processes can be explained by knowing this connection.

A small fungal enzyme could play a significant role in simplifying the development and manufacture of drugs, according to Rice University scientists.

Using simple blood tests could help researchers identify children who have been misidentified as having severe malaria, according to a study published today in eLife.

A recent collaboration between scientists in Michigan and Massachusetts as well as South Korea resulted in the development of a novel and broadly applicable molecular assay that used a model fungus to investigate how plant fungal pathogens circumvent the bioactivity of SDHIs. Through this analysis, they were able to successfully validate known mechanisms of fungicide resistance in several agriculturally important fungal pathogens.

Researchers at Linköping University, Sweden, have developed a method that may lead to new types of displays based on structural colours. The discovery opens the way to cheap and energy-efficient colour displays and electronic labels. The study has been published in the scientific journal Advanced Materials.

A transplant of healthy gut microbes followed by fibre supplements benefits patients with severe obesity and metabolic syndrome, according to University of Alberta clinical trial findings published today in Nature Medicine.

A skin pigmentation mechanism that can darken the color of human skin as a natural defense against ultraviolet (UV)-associated cancers has been discovered by scientists at Massachusetts General Hospital (MGH).

ORNL story tips: Powered by nature, get on the bus, accelerating methane, helping JET soar, charged up planning and building a better thermostat

University of California San Diego School of Medicine researchers identified a possible link between inadequate exposure to ultraviolet-B (UVB) light from the sun and an increased risk of colorectal cancer.

St. Jude Children's Research Hospital scientists created a registry for molecular analysis of pediatric melanoma that provides insight into treatment.
