COVID-19 (SARS-CoV-2) infections tend to be more severe among older adults and males, yet the mechanisms underlying increased mortality in these two demographics are unknown. A study published in the open access journal PLOS Biology on September 8, 2020 by Nicole Lieberman and Alexander Greninger at University of Washington and colleagues suggests that varying immune responses to SARS-CoV-2 due to age and sex may depend on viral load and the time-course of infection

What The Study Did: This study examined the location of mass shootings (four or more people injured or killed by a firearm) last year relative to schools and other places frequented by children.

Authors: Michael L. Nance, M.D., of Children's Hospital of Philadelphia, is the corresponding author.

ANN ARBOR, Mich. - As your preschooler plays an alphabet game, does a puzzle or dresses up a favorite character through an app on a phone or tablet, companies may be stealthily collecting their personal information for marketing purposes.

Just like adults, children often leave digital footprints disclosing what websites they use and which games they play as well as data identifying their location and device.

Except their information is supposed to be off limits to advertisers.

A new UC Riverside study finds that climate change will have a devastating effect on the greater Palm Springs area's dominant industry -- tourism.

Thousands known as "snowbirds" flock to the region annually from elsewhere in the country to escape freezing winters. However, due to climate change, the number of days above 85 degrees between November and April is projected to increase by up to 150% by the end of the century.

Tina Cheng, M.D., M.P.H., director of the Department of Pediatrics at Johns Hopkins Children's Center and a Chinese academic pediatrician, and her daughter, Alison Conca-Cheng, a third-year medical student, wrote a commentary published in Pediatrics on Sept.

Around 100,000 years ago, the climate worsened abruptly and the environment of Central-Eastern Europe shifted from forested to open steppe/taiga habitat, promoting the dispersal of wooly mammoth, wooly rhino and other cold adapted species from the Arctic. Neanderthals living in these territories suffered severe demographic contractions due to the new ecological conditions and only returned to the areas above 48° N latitude during climatic ameliorations.

A new study from North Carolina State University and the University of Virginia finds that experiences with racism are associated with increased social consciousness and social justice activism in Black youth.

Future wireless networks of the 6th generation (6G) will consist of a multitude of small radio cells that need to be connected by broadband communication links. In this context, wireless transmission at THz frequencies represents a particularly attractive and flexible solution. Researchers at Karlsruhe Institute of Technology (KIT) have now developed a novel concept for low-cost terahertz receivers that consist of a single diode in combination with a dedicated signal processing technique.

A University of Houston researcher is reporting that the brains of older women with Type 2 diabetes do not use as much oxygenated blood as those who don't have the disease. The research is the first to point to changes in blood use in the brain as the primary reason for diabetes-related deficits in motor function. It also furthers the understanding of sensory and motor symptoms as a precursor to developing dementia and Alzheimer's diseases, both of which are linked to diabetes.

ITHACA, N.Y. - Scientists have detected signs of a frog listed extinct and not seen since 1968, using an innovative technique to locate declining and missing species in two regions of Brazil.

The frog, Megaelosia bocainensis, was among seven total species - including four other declining species, and two that had disappeared locally for many years - that were detected. The findings appeared in a paper, "Lost and Found: Frogs in a Biodiversity Hotspot Rediscovered with Environmental DNA," published in August in Molecular Ecology.

HSE University economists (Ludmila Zasimova and Marina Kolosnitsyna analyzed two data sets for Russian regions in 2010-2016: the official statistics of the Russian Statistics Agency on alcohol sales and estimates of unregistered alcohol consumption modeled by the study's authors relying on the Ministry of Health's own methodology.

WASHINGTON -- Researchers have developed a tiny fiber optic force sensor that can measure extremely slight forces exerted by small objects. The new light-based sensor overcomes the limitations of force sensors based on micro-electro-mechanical sensors (MEMS) and could be useful for applications from medical systems to manufacturing.

A new study using induced pluripotent stem cell (iPSC) technology links astrocyte dysfunction to Parkinson's disease (PD) pathology. The study carried out at the University of Eastern Finland and published in Scientific Reports highlights the role of brain astrocyte cells in PD pathology and the potential of iPSC-derived cells in disease modelling and drug discovery.

Researchers at the Estonian University of Life Sciences and Swedish University of Agricultural Sciences in collaboration with Finnish scientists, developed a methodology that uses next-generation sequencing technology for fast and efficient screening of genetic diversity of fish eye parasites.

WASHINGTON -- Infants and young children have brains with a superpower, of sorts, say Georgetown University Medical Center neuroscientists. Whereas adults process most discrete neural tasks in specific areas in one or the other of their brain's two hemispheres, youngsters use both the right and left hemispheres to do the same task. The finding suggests a possible reason why children appear to recover from neural injury much easier than adults.
