Researchers have found that the anti-malarial drug quinine can block a cell’s ability to take up the essential amino acid tryptophan, a discovery that may explain many of the adverse side-effects associated with quinine. Once confirmed, these findings would suggest that dietary tryptophan supplements could be a simple and inexpensive way to improve the performance […]
In cell studies, seaweed extract outperforms remdesivir in blocking COVID-19 virus
In a test of antiviral effectiveness against the virus that causes COVID-19, an extract from edible seaweeds substantially outperformed remdesivir, the current standard antiviral used to combat the disease. Heparin, a common blood thinner, and a heparin variant stripped of its anticoagulant properties, performed on par with remdesivir in inhibiting SARS-CoV-2 infection in mammalian cells. […]
Particulate plutonium released from the Fukushima Daiichi meltdowns
Small amounts of plutonium (Pu) were released from the damaged Fukushima Daiichi Nuclear Power Plant (FDNPP) reactors into the environment during the site’s 2011 nuclear disaster. However, the physical, chemical, and isotopic form of the released Pu has remained unknown. Now, recent work published in the journal Science of the Total Environment has shown that Pu was […]
Cloth masks: Dangerous to your health?
The widespread use of cloth masks by healthcare workers may actually put them at increased risk of respiratory illness and viral infections and their global use should be discouraged, according to a UNSW study. The results of the first randomized clinical trial (RCT) to study the efficacy of cloth masks were published in the journal BMJ […]
Track the Coronavirus Outbreak on Johns Hopkins Live Dashboard
This tracker from Johns Hopkins University provides realtime information and counts cases of COVID-19 coronavirus in China, as well as around the world, including numbers of deaths, recovered patients, and countries affected. The World Health Organization has its own coronavirus dashboard as well, but includes only its own information, whereas the Hopkins team synthesizes data from WHO and four […]
Potential of using psychedelic drugs in psychiatry
Before they were banned about a half century ago, psychedelic drugs like LSD and psilocybin showed promise for treating conditions including alcoholism and some psychiatric disorders. In a commentary publishing April 2 in the journal Cell, part of a special issue on medicine, researchers say it’s time for regulators, scientists, and the public to “revisit drugs […]
Gardening helps to grow positive body image
New research has found that allotment gardening promotes positive body image, which measures someone’s appreciation of their own body and its functions, and an acceptance of bodily imperfections. The study, published in the journal Ecopsychology and led by Professor Viren Swami of Anglia Ruskin University (ARU), involved 84 gardeners from 12 urban allotment sites in north London. […]
How silver ions kill bacteria
The antimicrobial properties of silver have been known for centuries. While it is still a mystery as to exactly how silver kills bacteria, University of Arkansas researchers have taken a step toward better understanding the process by looking at dynamics of proteins in live bacteria at the molecular level. Traditionally, the antimicrobial effects of silver […]
Removing the novel coronavirus from the water cycle
Scientists know that coronaviruses, including the SARS-CoV-19 virus responsible for the COVID-19 pandemic, can remain infectious for days — or even longer — in sewage and drinking water. Two researchers, Haizhou Liu, an associate professor of chemical and environmental engineering at the University of California, Riverside; and Professor Vincenzo Naddeo, director of the Sanitary Environmental […]
Will Wearing a Mask Protect You Against Coronavirus?
Fear of coronavirus infection has led to a massive increase in sales of surgical face masks and respirators. While the evidence is conflicting, some studies suggest healthy people do limit their chances of infection if wearing a face mask, especially properly fitted N95 or N100 respirators. With 663,828 reported COVID-19 cases across 177 countries and territories as […]
