NIH supports research on how pathogens evolve

For several years, physicist John Barton at the University of California, Riverside, has been working on developing models to understand and predict how pathogens, such as HIV, evolve. This research pursuit has just received support from the National Institutes of Health.

Oxytocin can aid in the control and prevention of osteoporosis

Oxytocin, produced by the hypothalamus and sometimes known as the "love hormone" for its involvement in pair bonding and orgasm, can be a strong ally in the control and prevention of osteoporosis, according to a study by scientists at São Paulo State University in Brazil.

CRISPR-based COVID-19 surveillance

A recent US study available on the medRxiv preprint server supports the use of self-collected oropharyngeal swabs, together with CRISPR- and PCR-based diagnostic assays, as rapid, feasible and reliable approach for the surveillance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in university students and other asymptomatic individuals

Mouthwashes could lower the transmission of SARS-CoV-2

Sars-Cov-2 viruses can be inactivated using certain commercially available mouthwashes. This was demonstrated in cell culture experiments by virologists from Ruhr-Universität Bochum together with colleagues from Jena, Ulm, Duisburg-Essen, Nuremberg and Bremen. High viral loads can be detected in the oral cavity and throat of some Covid-19 patients.

Researchers identify new treatment for osteoarthritis

The study results revolve around the long-established idea that machines within animal and human cells turn the sugars, fats, and proteins we eat into energy used by the body's millions of cells.

Mathematical model shows how brain remains stable amid varying disturbances

Whether you are playing Go in a park amid chirping birds, a gentle breeze and kids playing catch nearby or you are playing in a den with a ticking clock on a bookcase and a purring cat on the sofa, if the game situation is identical and clear, your next move likely would be, too, regardless of those different conditions.

Chronic fatigue syndrome and Gulf War illness produce different patterns of brain activity after moderate exercise

A brain imaging study of veterans with Gulf War illness (GWI) and patients with chronic fatigue syndrome (CFS) (sometimes called myalgic encephalomyelitis), has shown that the two illnesses produce distinctly different, abnormal patterns of brain activity after moderate exercise.

COVID-19 patient with repeatedly undetectable SARS-CoV-2 antibodies

A recent case study published in the Journal of Applied Laboratory Medicine in August 2020 illustrates this with its finding of persistent seronegativity in a patient confirmed to be SARS-CoV-2 positive.

A titanium oxide nanowire-based air filter can trap and destroy pathogens

Filter “paper” made from titanium oxide nanowires is capable of trapping pathogens and destroying them with light. This discovery by an EPFL laboratory could be put to use in personal protective equipment, as well as in ventilation and air conditioning systems.

Researchers establish new 3D in vitro model for pulmonary arterial hypertension

Pulmonary arterial hypertension is a rare--albeit deadly--disease that affects the arteries of the lung. In PAH, abnormal growth of cells of the vascular media--or the elastic wall--of the pulmonary arteries, called pulmonary arterial smooth muscle cells, results in thickening of the walls.

Advanced analysis offers new insights into immune system’s role in severe COVID-19

By conducting advanced analyses of immune system activation in patients with severe COVID-19, researchers at Karolinska Institutet have managed to identify several cell types that play a key part in the immune response to the new coronavirus and the hyperinflammation seen in severe cases of the disease.
