Teacher-perceived conflict predicts lower interest in reading, math among kindergarteners

Teacher-perceived conflict predicts lower interest and pre-academic skills in math and literacy among kindergarteners, a new study from Finland shows.

Study explains the global burden of disability from musculoskeletal conditions

Musculoskeletal disorders--which affect muscles, tendons, ligaments, bones, and joints--can severely affect individuals' physical and mental health, and they're especially prevalent among aging adults.

Researchers study link between gut microbiome and the brain in humans, rodents

Despite extensive support for relationships between the gut microbiome and the brain (the "microbiota-gut-brain axis") in humans and rodents, little is known about these relationships in other animals, leaving questions about this system's generality.

Researchers identify antibodies that prevent SARS-CoV-2 from infecting human cells

The ability of SARS-CoV-2 to infect cells depends on interactions between the viral spike protein and the human cell surface protein ACE2.

Study reveals new mechanism underlying immune-cell activation

When antibody-producing immune cells encounter infectious pathogens for the first time, they engage a signal cascade to generate a massive activation signal within seconds.

Scientists identify a brain structure important for decision making

Our minds can help us make decisions by contemplating the future and predicting the consequences of our actions.

Study shows T cells can prevent Zika infection in mice

Where Aedes mosquitoes fly, Zika virus may not be far behind. Although the explosive 2015–2016 Zika epidemics in the Americas are behind us, Zika may re-emerge, and "in many countries, Zika may be spreading in silence," says Sujan Shresta, Ph.D., a professor at La Jolla Institute for Immunology (LJI).

Researchers explore how different birth experience affect the developing nervous system

It is an experience we all share, as miraculous as it is mysterious. Birth. Today, roughly one in three births in the United States occurs via cesarean section or C-section.

Scientists study the multiscale spatial organization of the brain

The architecture of the brain supports cognitive and behavioral functions and it is extremely complex with connections at multiple layers that interact with each other.

Green tea and some fruit juices inhibit SARS-CoV-2 in vitro

Green tea, chokeberry juice, and pomegranate juice killed flu and SARS-CoV-2 viruses when incubated with the viruses in vitro. Thus, oral rinsing using these might be effective in preventing COVID-19.

Election rallies linked to an increase in COVID-19 hospitalizations

Researchers from Ben-Gurion University, Israel, Harvard Medical School, Boston, and Tel Aviv University, Israel, have studied the correlation between large gatherings and hospitalization risk due to COVID-19. Their study titled, “Association of Mass Gatherings and COVID-19 Hospitalization,” was published as a preprint on the medRxiv server.

Novel approach for modeling spread of infectious disease

The rapid spread of SARS-CoV-2 across the world despite the early shutdown of borders and the cessation of international travel has sparked interest and given rise to changes in knowledge regarding the spread of infections.

Case study reports prolonged infectious SARS-CoV-2 shedding from an asymptomatic leukemia patient

The majority of people infected with SARS-CoV-2 appear to actively shed infectious virus for about 8 days, but there is a wide range of variability from person to person.

Ebola virus antibodies found in people prior to 2018 DRC outbreak

Scientists found antibodies to Ebola virus in people up to a year before the 2018 Ebola virus disease outbreak began in the Eastern Democratic Republic of Congo, or DRC.

Zinc-embedded polyamide fabrics are effective in absorbing and inactivating SARS-CoV-2

An international team of scientists has recently demonstrated that zinc-embedded polyamine fibers can effectively absorb and inactivate human respiratory viruses, including influenza A virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Thus, a face mask or other personal protective equipment (PPE) made from this fiber is expected to provide better protection against viral transmission.

Computational study reveals SARS-CoV-2 spike protein structural stability

Using dynamic contact maps and energy differences between different conformations of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (or S-protein), an international team of researchers have recently published an article on the bioRxiv preprint server showing the different stable conformations of the spike protein.

An analysis of genetic diversity of D614G mutation in SARS-CoV-2

A new study published in the preprint server bioRxiv in November 2020 reports that the effect of the mutation is minimal, in terms of pathogenicity or altered response to neutralizing antibodies elicited against the native virus strain.

D614G mutation enhances stability of SARS-CoV-2 spike protein

A new study, published on the preprint server bioRxiv in November 2020 by researchers at the Indian Institute of Science, has explored this issue further. The researchers have found that this mutation is associated with structural and energetic changes that cause this spike variant to become more available during infection, thus rendering the associated strain more infective.

Ozone water found to rapidly inactivate SARS-Cov-2

As the coronavirus disease 19 (COVID-19) pandemic appears here to stay, a new study published on the preprint server bioRxiv* in November 2020 reports an effective and rapid inactivation tactic for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2); namely, through the use of ozone water.
