Johns Hopkins Medicine researchers report that new experiments with genetically engineered mice have found clear connections among a range of autism types and abnormalities in brain cells whose chemical output forges platonic (non-sexual) feelings of love and sociability.
A study published today in Educational Researcher, a peer-reviewed journal of the American Educational Research Association, provides preliminary projections of the impact of COVID-19-related school closures in spring 2020 on student learning. The study authors found that compared to a typical year, students likely did not gain as much academically during the truncated 2019–20 school year and likely lost more of those gains due to extended time out of school.
President Trump’s supporters and opponents are increasingly at odds over the coronavirus pandemic, according to a new survey led by researchers from Rutgers University–New Brunswick and University of California-Berkley.
A small energy harvesting device that can transform subtle mechanical vibrations into electrical energy could be used to power wireless sensors and actuators for use in anything from temperature and occupancy monitoring in smart environments, to biosensing within the human body. In research recently published in the Journal of Micromechanics and Microengineering, engineers at Rensselaer Polytechnic Institute developed a predictive model for such a device, which will allow researchers to better understand and optimize its functionalities.
Using sophisticated 3D genomic mapping and integrating with public data resulting from genome-wide association studies (GWAS), researchers at Children’s Hospital of Philadelphia (CHOP) have found significant genetic correlations between inflammatory bowel disease (IBD) and stress and depression. The researchers went on to implicate new genes involved in IBD risk that are enriched in both derived hypothalamic neurons, from a part of the brain that has a vital role in controlling stress and depression, and organoids derived from colon cells, a region more commonly studied in the context of IBD.

The National Science Foundation has awarded $39 million to a team of engineers and computer scientists at the University of California San Diego to build a first-of-its-kind testbed to better understand how to integrate distributed energy sources such as solar panels, wind turbines, smart buildings and electric vehicle batteries into the power grid. The goal is to make the testbed available to outside research teams and industry by 2025.
In a review of evidence from the most reliable data from randomized trials to find likely small-to-moderate effects of remdesivir, researchers say that totality of evidence compiled before the WHO trial results justifies compassionate use of remdesivir for severely ill patients. A smaller trial in China showed significantly decreased mean recovery time but no suggestion of a mortality benefit. ACTT-1 found the same mean recovery time and a suggestion of a mortality benefit that did not achieve statistical significance.
When startled, do all fish respond the same way? A few fish, like Mexican cavefish, have evolved in unique environments without any predators. To see how this lack of predation impacts escape responses that are highly stereotyped across fish species, scientists explored this tiny fish to determine if there are evolved differences in them. Findings reveal that the dramatic ecological differences between cave and river environments contribute to differences in escape behavior in blind cavefish and river-dwelling surface cavefish.

Determining a child’s best daily balance of sleep, activity and relaxation can be a challenge, but if you’re hoping to improve their academic results, then it’s time to cut back on chores and chill time, according to new research from the University of South Australia.
DALLAS – Oct. 29, 2020 – About half of all tumors have mutations of the gene p53, normally responsible for warding off cancer. Now, UT Southwestern scientists have discovered a new role for p53 in its fight against tumors: preventing retrotransposons, or “jumping genes,” from hopping around the human genome. In cells with missing or mutated p53, the team found, retrotransposons move and multiply more than usual. The finding could lead to new ways of detecting or treating cancers with p53 mutations.
In a large, statistically significant, one-of-a-kind study, researchers at Los Alamos National Laboratory have confirmed that the explosive called PETN (Pentaerythritol tetranitrate), stabilized with a polysaccharide coating, is resistant to changes in particle shape, size, and structure that can degrade detonator performance over time.

La retinopatía diabética es la causa más común de ceguera en los adultos de edad laboral; sin embargo, la mayoría de los estadounidenses de más de 40 años no conocen sus síntomas ni los factores de riesgo para esta afección común que amenaza la vista, según una encuesta encomendada por la Sociedad Estadounidense de Especialistas en Retina (American Society of Retina Specialists, ASRS).
Diabetic retinopathy is the leading cause of blindness among working-age adults, yet most Americans over 40 don’t know its symptoms or the risk factors for this common sight-threatening condition, according to a survey commissioned by the American Society of Retina Specialists (ASRS).
Red algae have persisted in hot springs and surrounding rocks for about 1 billion years. Now, a Rutgers-led team will investigate why these single-celled extremists have thrived in harsh environments – research that could benefit environmental cleanups and the production of biofuels and other products.
