SARS-CoV-2 RNA discovery unlocks new potential treatments
An international and multidisciplinary team led by researchers at the University of Oxford, University of Glasgow, and University of Heidelberg, has uncovered the interactions that SARS-CoV-2 RNA establishes with the host cell, many of which are fundamental for infection. These discoveries pave the way for the development of new therapeutic strategies for COVID-19 with broad-range antiviral potential.

For men, low testosterone means high risk of severe COVID-19
A new study from Washington University School of Medicine in St. Louis suggests that, among men, low testosterone levels in the blood are linked to more severe COVID-19. The study contradicts widespread assumptions that higher testosterone may explain why men, on average, develop more severe COVID-19 than women do.

Association between bitter taste receptor types, clinical outcomes among patients with COVID-19
What The Study Did: This study evaluates the association between bitter taste receptor types (supertasters who experience greater intensity of bitter tastes; tasters; and nontasters who experience low intensity of bitter tastes or no bitter tastes) and outcomes after infection with SARS-CoV-2.

Silver attacks bacteria, gets 'consumed'
As antibiotic-resistant bacteria become more prevalent, silver has seen steep growth in its use in things like antibacterial coatings. Still, a better understanding can provide clues on how to best apply it. In Chemical Physics Reviews, researchers monitored the interaction of silver nanoparticles with a nearby E. coli culture and found the silver undergoes several dramatic changes. Most notably, the E. coli cells caused substantial transformations in the size and shape of the silver particles.

'Rejuvenating' the Alzheimer's brain
Alzheimer's disease is the main cause of dementia and current therapeutic strategies cannot prevent, slow down or cure the pathology. The disease is characterized by memory loss, caused by the degeneration and death of neuronal cells in several regions of the brain, including the hippocampus. Researchers from the Netherlands Institute for Neuroscience have identified a small molecule that can be used to rejuvenate the brain and counteract the memory loss.

Russian scientists synthesize effective compounds for anticancer drugs
New effective compounds, which can be endogenous donors of a signaling molecule - hydrogen sulfide in the body, were synthesized by SUSU scientists. Due to this property, the obtained compounds are potential drugs with a cancer-preventing effect. The research work was published in the Russian Chemical Bulletin (Q3).

Researchers seek deeper understanding on how cells in the body operate
Cells sense and respond to the mechanical properties of the cellular microenvironment in the body. Changes in these properties, which occur in a number of human pathologies, including cancer, can elicit abnormal responses from cells. How the cells adapt to such changes in the mechanical microenvironment is not well understood.

"Bite" defects in bottom-up graphene nanoribbons
Scientists at Empa and EPFL have identified a new type of defect as the most common source of disorder in on-surface synthesized graphene nanoribbons, a novel class of carbon-based materials that may prove extremely useful in next-generation electronic devices. The researchers identified the atomic structure of these so-called "bite" defects and investigated their effect on quantum electronic transport. These kinds of defective zigzag-edged nanoribbons may provide suitable platforms for certain applications in spintronics.

Superflimsy graphene turned ultrastiff by optical forging
Graphene is an ultrathin material characterized by its ultrasmall bending modulus, superflimsiness. Now the researchers at the Nanoscience Center of the University of Jyväskylä have demonstrated how an experimental technique called optical forging can make graphene ultrastiff, increase its stiffness by several orders of magnitude. The research was published in Nature Partner Journals in May 2021.
