Through the thin-film glass, researchers spot a new liquid phase

Jul 26 2021 - 00:07
A new study describes a new liquid phase in thin films of a glass-forming molecules. These results demonstrate how these glasses and other similar materials can be fabricated to be denser and more stable, providing a framework for developing new applications and devices through better design.

New breakthrough to help immune systems in the fight against cancer

Jul 26 2021 - 00:07
New research has identified potential treatment that could improve the human immune system's ability to search out and destroy cancer cells within the body. Scientists have identified a way to restrict the activity of a group of cells which regulate the immune system, which in turn can unleash other immune cells to attack tumours in cancer patients.

Scientists model 'true prevalence' of COVID-19 throughout pandemic

Jul 26 2021 - 00:07
University of Washington scientists have developed a statistical framework that incorporates key COVID-19 data -- such as case counts and deaths due to COVID-19 -- to model the true prevalence of this disease in the United States and individual states. Their approach projects that in the U.S. as many as 60% of COVID-19 cases went undetected as of March 7, 2021, the last date for which the dataset they employed is available.

Administering opioids to pregnant mice alters behavior and gene expression in offspring

Jul 26 2021 - 00:07
Mice exposed to the opioid oxycodone before birth experience permanent changes in behavior and gene expression. The new research published in eNeuro highlights a need to develop safer types of painkillers for pregnant women.

Rare inherited variants in previously unsuspected genes may confer significant risk for autism

Jul 26 2021 - 00:07
Researchers have identified a rare class of genetic differences transmitted from parents without autism to their affected children with autism and determined that they are most prominent in "multiplex" families with more than one family member on the spectrum. These findings are reported in Recent ultra-rare inherited variants implicate new autism candidate risk genes, a new study published in Nature Genetics.

Plant root-associated bacteria preferentially colonize their native host-plant roots

Jul 26 2021 - 00:07
An international team of researchers from the Max Planck Institute for Plant Breeding Research and the University of Åarhus in Denmark have discovered that bacteria from the plant microbiota are adapted to their host species. In a newly published study, they show how root-associated bacteria have a competitive advantage when colonizing their native host, which allows them to invade an already established microbiota.

Second COVID-19 mRNA vaccine dose found safe following allergic reactions to first dose

Jul 26 2021 - 00:07
A new study reports that among individuals who had an allergic reaction to their first mRNA COVID-19 vaccine dose, all who went on to receive a second dose tolerated it. Even some who experienced anaphylaxis following the first dose tolerated the second dose.

Exosome formulation developed to deliver antibodies for choroidal neovascularization therapy

Jul 26 2021 - 00:07
Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences, Beijing Chaoyang Hospital and the University of Queensland have developed a new formulation based on regulatory T-cell exosomes (rEXS) to deliver vascular endothelial growth factor (VEGF) antibodies for choroidal neovascularization therapy.

65+ and lonely? Don't talk to your doctor about another prescription

Jul 26 2021 - 00:07
Lonely, older adults are nearly twice as likely to use opioids to ease pain and two-and-a-half times more likely to use sedatives and anti-anxiety medications, putting themselves at risk for drug dependency, impaired attention, falls and other accidents, and further cognitive impairment, according to a study by researchers at UC San Francisco.

Safety of second dose of mRNA COVID-19 vaccines after first-dose allergic reactions

Jul 26 2021 - 00:07
What The Study Did: Researchers examined the safety of the second dose of the Pfizer-BioNTech or Moderna COVID-19 vaccines in patients who experienced an allergic reaction to the first dose.

Brain's 'memory center' needed to recognize image sequences but not single sights

Jul 26 2021 - 00:07
The visual cortex stores and remembers individual images, but when they are grouped into a sequence, mice can't recognize that without guidance from the hippocampus, according to a new study by neuroscientists at MIT's Picower Institute for Learning and Memory.

International experts call for a unified public health response to NAFLD and NASH epidemic

Jul 26 2021 - 00:07
There is an urgent need to develop and implement effective screening, diagnosis and treatment strategies for patients with nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH), common liver conditions with a rising burden in the U.S. and globally. This is particularly important for the most at-risk patients, those with diabetes and obesity.

Misplaced trust: When trust in science fosters pseudoscience

Jul 26 2021 - 00:07
People who trust science are more likely to believe and disseminate false claims containing scientific references than people who do not trust science, a study finds. Reminding people of the value of critical evaluation reduces belief in false claims, but reminding them of the value of trusting science does not.

International collaboration of scientists rewrite the rulebook of flowering plant genetics

Jul 26 2021 - 00:07
Scientists around the world are collaborating on a project that is changing the way they trace the evolutionary history of flowering plants. By using new technology allowing them to rapidly retrieve and compare DNA sequences from among any of the 300,000 species of flowering plants, scientists are unraveling the 140-million-year history of the largest group of land plants on Earth and providing a framework to protect vulnerable species and populations into the future.

New statement provides path to include ethnicity, ancestry, race in genomic research

Jul 26 2021 - 00:07
Historically marginalized racial and ethnic groups and Indigenous peoples have significant cardiovascular health inequities, and these groups are underrepresented in genetic and genomic research.Almost 80% of participants in genomic research are of European ancestry, yet this group makes up just 16% of the global population.Heart-disease risk calculations and information about how different populations respond to treatment with medicines based on genetic studies are less accurate when used to assess risk for historically underrepresented or Indigenous peoples.
