Epstein-Barr virus reactivation may play a role in long COVID and severe COVID-19 cases

Two recently published studies available on the National Institutes of Health website indicate Epstein-Barr virus (EBV) reactivation may play a role both in the development of long COVID symptoms, as well as severe COVID-19 cases.

New motor imagery-based BMI system turns intentions into actions

A new wearable brain-machine interface (BMI) system could improve the quality of life for people with motor dysfunction or paralysis, even those struggling with locked-in syndrome – when a person is fully conscious but unable to move or communicate.

Study reveals calcium's role in directing blood flow in the brain

Unlike the rest of the body, there is not enough real estate in the brain for stored energy. Instead, the brain relies on the hundreds of miles of blood vessels within it to supply fresh energy via the blood. Yet, how the brain expresses a need for more energy during increased activity and then directs its blood supply to specific hot spots was, until now, poorly understood.

Emerging SARS-CoV-2 mutations L452R & Y453F evade cellular immunity

The study, published in the journal Cell Host & Microbe, also showed emerging mutations L452R and Y453F in the SARS-CoV-2 spike receptor-binding motif evade (HLA) A24-restricted cellular immunity. Meanwhile, the L452R enhances spike stability, viral fusogenicity, and viral infectivity. Hence, the findings suggest that HLA-restricted cellular immunity potentially affects the evolution of viral phenotypes.

Use of topical fluorides for caries prevention in primary teeth

Alexandria, Va., USA - Parach Sirivichayakul, Mahidol University, Bangkok, Thailand, presented the poster "Preventing Approximal Caries in Primary Teeth With Topical Fluorides" at the virtual 99th General Session & Exhibition of the International Association for Dental Research (IADR), held in conjunction with the 50th Annual Meeting of the American Association for Dental Research (AADR) and the 45th Annual Meeting of the Canadian Association for Dental Research (CADR), on July 21-24, 2021.

Study finds link between residential proximity to oil and gas drilling and lower birthweights in infants

A new study from Oregon State University found that infants born within 3 kilometers of oil and natural gas drilling facilities in Texas had slightly lower birthweights than those born before drilling began in their vicinity.

Structural home repairs in low-income neighborhoods linked with reduced crime rates

Investing in structural home repairs in historically segregated, low-income, Black, and Latino neighborhoods have been associated with reduced crime rates.

Survey provides insights into 'pure awareness' state experienced by meditators

In the context of meditation practice, meditators can experience a state of "pure awareness" or "pure consciousness", in which they perceive consciousness itself.

Scientist explore conserved RNA elements as potential targets for anti-SARS-CoV-2 drugs

The study, published in the journal Angewandte Chemie International Edition, identified many small molecules that bind to certain parts of the SARS-CoV-2 genome that are less likely altered by mutations using dedicated substance libraries. The scientists derived key functional units and groups in ligands for effective and safe targeting of SARS-CoV-2 RNA.

Study: Older adults are just as capable as younger people of learning behaviors that benefit others

Older adults may be slower to learn actions and behaviors that benefit themselves, but new research shows they are just as capable as younger people of learning behaviors that benefit others.

Two-dose regimen of mRNA vaccines provides protection against Alpha and Beta variants in France

Over the past six months, the World Health Organization has categorized four SARS-CoV-2 variants as being "of concern" because they are more transmissible or may escape the immune response.

SARS-CoV-2 proteins manipulate autophagy

The ongoing coronavirus pandemic (COVID-19) has claimed more than 4.1 million lives worldwide. This pandemic is caused by a novel single-stranded RNA virus, namely, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that was first reported in 2019 in Wuhan, China. The rapid spread of this virus is attributed to its high infectiousness and its ability to escape and counteract host immune responses, e.g., autophagy.

Experts call for immediate action to ensure physical activity is built into everyday lives

Not enough progress has been made to address physical inactivity worldwide, with adolescents and people living with disabilities (PLWD) among the least likely populations to have the support needed to meet the World Health Organization (WHO)'s physical activity guidelines.

SARS-CoV-2 genomic surveillance identifies intricacies of stabilizing vs. destabilizing mutations

Some of these variants, known as variants of concern (VoC), have a much higher rate of transmission and increased mortality than the original SARS-CoV-2 strain. Therefore, it is imperative to assess the efficacy of the available vaccines against the circulating SARS-CoV-2 strains. In addition, tracking the continuously evolving genetic variants is also vital to prevent future outbreaks.
