Childhood abuse and trauma are linked to many health issues in adulthood. New research from the University of Georgia suggests that a history of childhood mistreatment could have negative ramifications for the children of people who experienced abuse or neglect in childhood.

In work that could one day help athletes as well as aging adults regenerate tissue more effectively, Salk scientists increased the regeneration of muscle cells in mice by activating the precursors of muscle cells.

Largest-ever study of viral load levels in patients with SARS-CoV-2: Researchers from Charité - Universitätsmedizin Berlin have analyzed the PCR samples of more than 25,000 persons with COVID-19. The team determined the viral loads of each individual sample and used their results to estimate levels of infectiousness. The research, which has been published in Science*, provides a clear idea of the infectiousness of the disease in different age groups and at different levels of disease severity.

Fusarium Head Blight is caused by a fungus that produces heat-stable trichothecene mycotoxins, which help the disease spread. To stop the spread, plant breeders are working to develop cultivars with improved resistance to FHB. A team of plant pathologists primarily based at Rutgers University recently generated wheat overexpressing two non-specific lipid transfer proteins and found that this enhanced protection against the fungus and led to a reduction of one of the major mycotoxins.

Researchers know cosmic rays originate from the multitude of stars in the Milky Way and other galaxies. The difficulty is tracing the particles to specific sources, because the turbulence of interstellar gas, plasma, and dust causes them to scatter and rescatter in different directions. In AIP Advances, researchers developed a simulation model to better understand these and other cosmic ray transport characteristics, with the goal of developing algorithms to enhance existing detection techniques.

Much of the conversation around COVID-19 focuses on death and survival. But 45% of patients hospitalized for the virus at Michigan Medicine during the pandemic's first wave experienced significant functional decline. Nearly 20% were discharged to a location other than their home. Researchers say this information highlights the true impact of COVID-19.

With a global impetus toward utilizing more renewable energy sources, wind presents a promising, increasingly tapped resource. Despite the many technological advancements made in upgrading wind-powered systems, a systematic and reliable way to assess competing technologies has been a challenge. Researchers at Texas A&M University, in collaboration with international energy industry partners, have used advanced data science methods and ideas from the social sciences to compare the performance of different wind turbine designs.

Swedish and Danish journalists describe their role as monitorial to a greater extent than journalists from other Nordic countries. Journalists from Norway and Iceland state they have the least experience of political influence and thus differ from Finnish journalists. This is shown by a new comparative study published by Nordicom at the University of Gothenburg.

An international and multidisciplinary team led by researchers at the University of Oxford, University of Glasgow, and University of Heidelberg, has uncovered the interactions that SARS-CoV-2 RNA establishes with the host cell, many of which are fundamental for infection. These discoveries pave the way for the development of new therapeutic strategies for COVID-19 with broad-range antiviral potential.

The research team of Gero, a Singapore-based biotech company in collaboration with Roswell Park Comprehensive Cancer Center in Buffalo NY, announces a publication in Nature Communications, a journal of Nature portfolio, presenting the results of the study on associations between aging and the loss of the ability to recover from stresses.

A new study from Washington University School of Medicine in St. Louis suggests that, among men, low testosterone levels in the blood are linked to more severe COVID-19. The study contradicts widespread assumptions that higher testosterone may explain why men, on average, develop more severe COVID-19 than women do.

What The Study Did: Rates of depression, anxiety, suicidal thoughts and posttraumatic stress disorder among current and former coal miners in the United States were examined in this study.

What The Study Did: Researchers examined if circulating sex hormones are associated with disease severity in patients with COVID-19.

What The Study Did: This study evaluates the association between bitter taste receptor types (supertasters who experience greater intensity of bitter tastes; tasters; and nontasters who experience low intensity of bitter tastes or no bitter tastes) and outcomes after infection with SARS-CoV-2.

As antibiotic-resistant bacteria become more prevalent, silver has seen steep growth in its use in things like antibacterial coatings. Still, a better understanding can provide clues on how to best apply it. In Chemical Physics Reviews, researchers monitored the interaction of silver nanoparticles with a nearby E. coli culture and found the silver undergoes several dramatic changes. Most notably, the E. coli cells caused substantial transformations in the size and shape of the silver particles.

Bottom Line: In a new recommendation statement, the U.S. Preventive Services Task Force (USPSTF) recommends that clinicians offer pregnant adolescents and adults effective behavioral counseling interventions aimed at promoting healthy weight gain and preventing excess gestational weight gain in pregnancy.

Alzheimer's disease is the main cause of dementia and current therapeutic strategies cannot prevent, slow down or cure the pathology. The disease is characterized by memory loss, caused by the degeneration and death of neuronal cells in several regions of the brain, including the hippocampus. Researchers from the Netherlands Institute for Neuroscience have identified a small molecule that can be used to rejuvenate the brain and counteract the memory loss.

Scientists from the University of Bath in the UK explore racemases and propose strategies for finding drugs that target these important enzymes.

New effective compounds, which can be endogenous donors of a signaling molecule - hydrogen sulfide in the body, were synthesized by SUSU scientists. Due to this property, the obtained compounds are potential drugs with a cancer-preventing effect. The research work was published in the Russian Chemical Bulletin (Q3).

To improve the development of new saliva-based diagnostic tests and personalized medicine, the National Institute of Dental and Craniofacial Research (NIDCR) has supported the development of the Human Salivary Proteome Wiki, the first public platform that catalogs and curates data on each of the thousands of proteins within our saliva.
