Doctor in Israel reinfected with COVID-19 three months after recovering

There is still a lot to learn about coronavirus disease (COVID-19), which is currently ravaging across the globe. Though scientists are slowly gaining a better understanding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), it is still unclear if being infected once may provide long-lasting immunity against the novel coronavirus.

More than half of American children lack cardiorespiratory fitness

A new study strengthens the claim that children today are not as healthy as those decades ago. In fact, the study by researchers on behalf of the American Heart Association (AHA) has found that nearly 60 percent of American children do not have healthy cardiorespiratory fitness (CRF), a key measure of physical fitness and overall health.

New nanoparticle vaccine for SARS-CoV-2 shows protective traits in preclinical study

A new nanoparticle vaccine for SARS-CoV-2, the virus that causes COVID-19, has shown hints of protection and immunity in a preclinical study, safely eliciting the production of antibodies and antiviral T cell responses in mice and pigtail macaques.

An abundance of biomolecules linked to COVID-19 status and severity

Tapping into the potential of the multi-omic method to uncover functional connections between various classes of biomolecules, researchers from notable institutions in the United States have discovered sets of co-varying molecules that shed light on coronavirus disease (COVID-19) pathophysiology and provide treatment opportunities.

Cyanobacterial blooms in Florida waters release multiple toxins detrimental to human health

In 2018, cyanobacteria from nutrient-rich waters in Lake Okeechobee were released down the Caloosahatchee river at the same time that red tides were gathering along the Florida west coast, potentially exposing coastal residents to a mixture of toxins.

Researchers identify underlying mechanism for metabolic memory and diabetic complications

For people with diabetes, vascular complications like kidney disease and atherosclerosis, which can lead to poor health and even death, are seen at increased rates.

Involvement of nicotine receptors in COVID-19

Researchers from the University of Bristol, Oxford Brookes University and the University of California San Diego neatly demonstrated how the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exhibits high affinity for nicotinic acetylcholine receptors (nAChRs), with significant implications for coronavirus disease (COVID-19) pathology and infectivity. Their findings are published on the bioRxiv* preprint server.

Age-related hearing loss mainly caused by damage to hair cells, study shows

In a new study of human ear tissues, hearing scientists have demonstrated that age-related hearing loss, also called presbycusis, is mainly caused by damage to hair cells, the sensory cells in the inner ear that transform sound-induced vibrations into the electrical signals that are relayed to the brain by the auditory nerve.

Prostate tumors reactivate dormant molecular program during metastatic progression

When prostate cancer progresses to a more-dangerous metastatic state, it does so by resurrecting dormant molecular mechanisms that had guided the fetal development of the prostate gland but had been subsequently switched off, say scientists from Dana-Farber Cancer Institute.

New assay improves detection of SARS-CoV-2 antibodies

Researchers at the University of California Santa Cruz have developed a new assay for the detection of antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that they say provides significant advantages over the techniques currently used.

Study reveals the roles of non-REM and REM sleep in visual perceptual learning

Which sleep stage is most important for learning: REM or non-REM? Does sleep improve learning by enhancing skills while people snooze, or by cementing those skills in the brain so that they're less likely to forget them? Do these processes occur every time someone sleeps, or only after they have learned something new?
