Researchers from Umeå have found a new way to synthesize graphene oxide which has significantly fewer defects compared to materials produced by most common method. Similarly good graphene oxide could be synthesized previously only using rather dangerous method involving extremely toxic fuming nitric acid. Graphene oxide is often used to produce graphene by removing oxygen. … Read more
The evolutionary status of HD 1936. Credit: Çalışkan et al, 2024 Using the Ankara University Kreiken Observatory (AUKR) in Turkey, astronomers have performed high-resolution spectroscopic observations of a metal-poor star known as HD 1936. Results of the observations campaign, published February 15 on the preprint server arXiv, shed more light on the chemical composition of … Read more
From forgetfulness to difficulties concentrating, many people who have long Covid experience âbrain fogâ. Now researchers say the symptom could be down to the blood-brain barrier becoming leaky. The barrier controls which substances or materials enter and exit the brain. âItâs all about regulating a balance of material in blood compared to brain,â said Prof … Read more

Cycles of a diet that mimics fasting can reduce signs of immune system aging, as well as insulin resistance and liver fat in humans, resulting in a lower biological age, according to a new USC Leonard Davis School of Gerontology-led study. The study, which appears in Nature Communications on Feb. 20, adds to the body … Read more
(a) Conventional chimeric VLP vaccine requires first producing fusion viral proteins conjugated with self-assembling modules by challengeable gene design and expression and then carrying out unpredictable self-assembly of the proteins to get the vaccine particles. (b) VPNVax requires fewer structural designs of the viral proteins and could directly apply the production line of subunit proteins. … Read more
