Free-energy principle can explain how neural networks are optimized for efficiency

The RIKEN Center for Brain Science (CBS) in Japan, along with colleagues, has shown that the free-energy principle can explain how neural networks are optimized for efficiency.

Discovery opens up the possibility of pursuing new therapies for FOP

Fibrodysplasia ossificans progressiva (FOP) is a rare disease characterized by extensive bone growth outside of the normal skeleton that pre-empts the body's normal responses to even minor injuries. It results in what some term a "second skeleton," which locks up joint movement and could make it hard to breathe.

Study analyzes the link between consuming sweeteners during pregnancy and a child's risk of obesity

A new study investigates the link between consuming sweeteners during pregnancy and a child's risk of obesity. Pregnant rats fed with stevia or aspartame gave birth to pups that had a higher risk of obesity and specific changes in their gut microbiome. The findings highlight the importance of maternal nutrition during pregnancy.

Mutations in SARS-CoV-2 Omicron variant promote cell binding

Researchers in Germany, based on their recent study published in the journal ChemBioChem, have proposed that the elevated occurrence of positively charged amino acids in specific domains of the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) Omicron variant spike protein improves viral binding to cellular negatively charged receptors aiding in enhanced infectiousness.

Monitoring rodents for SARS-CoV-2 and other coronaviruses, Hong Kong

A new study published in the Centers for Disease Control and Prevention’s Emerging Infectious Diseases journal has hypothesized that locations with positive SARS-CoV-2 in sewage could be used as potential surveillance targets to analyze if pestiferous urban rodents shed SARS-CoV-2 into the environment.

Topical antiseptic Acriflavine inhibits SARS-CoV-2 and other betacoronaviruses

A new study, published in the journal Cell Chemical Biology, has reported the discovery of acriflavine (ACF), an effective inhibitor of SARS-CoV-2. This drug is a mixture of trypaflavines (3,6-diamino-10-methylacridinium chloride and 3,6-diamino-3-methylacridinium chloride) and proflavine (3,6-diaminoacridine).

Study reveals long-term mental impacts of repeated exposure to major disasters

Repeated exposure to major disasters does not make people mentally stronger, a recent study from the Texas A&M University School of Public Health found: individuals who have been repeatedly exposed to major disasters show a reduction in mental health scores.

Cannabidiol may improve innate immune response against SARS-CoV-2

A recent study shows evidence that cannabidiol, an important active ingredient in the Cannabis sativa plant, can augment the antiviral innate immune response and prophylactically prime the innate antiviral response of cells – enabling in turn improved response against viruses such as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Even mild SARS-CoV-2 respiratory-only infection can cause long-term neurologic damage

A new bioRxiv* preprint study led by Michelle Monje of Stanford University in California finds that a mild COVID-19 infection can produce long-term neurological damage. Persistent cognitive complications are one of many symptoms of long COVID, and the latest results suggest the severity of COVID-19 induced brain fog is similar to cancer’s “chemobrain.”

Study shows Omicron less severe than Delta among COVID-19 hospitalized patients

New research posted to the medRxiv* preprint server suggests the Omicron variant produces less severe COVID-19 symptoms than earlier severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants.

UV-C light prevents airborne transmission of SARS-CoV-2

Researchers demonstrate that ultraviolet light-C (UV-C) effectively prevents airborne transmission of SARS-CoV-2.

SARS-CoV-2 Omicron has similar infectious viral load to Delta

Researchers compare SARS-CoV-2 pre-variants of concern strains to the Delta and Omicron VOCs.

Research shows fewer deaths related to COVID-19 in Cape Town during fourth wave

Researchers observe changes in COVID-19-related deaths during the fourth wave of the COVID-19 pandemic in South Africa.

Asymptomatic COVID-19 patients less infectious than symptomatic patients

Researchers investigate the progression of infection in students and employees who tested positive for SARS-CoV-2 at Boston University.

Exploring the relationship between stem cells and COVID-19

Though COVID-19-related stem cell clinical research is still in its infancy, stem cell treatment offers extensive clinical application possibilities and a far-reaching relevance thanks to ongoing exploration of stem cell clinical research and data mining.

Naïve T cells suggested as critical to low mortality of children with COVID-19

A new study discusses how naïve T cells may contribute to lower mortality rates seen in children with COVID-19.

Exploring waning vaccine effectiveness over time

New research provides strong evidence against waning protection against symptomatic disease from both ChAdOx1-S and BNT162b2, but points out that protection against hospitalization and death remains at much higher levels for at least 20 weeks post-vaccination.
