Antibodies improve in quality for months after COVID-19 vaccination
Antibodies elicited by COVID-19 vaccination become steadily more powerful for at least six months after vaccination, according to a new study.
Accelerated ammonia synthesis holds promise for conversion of renewable energy
Scientists reveal a way to make ammonia from its constituent molecules of nitrogen and hydrogen at ambient pressure.
Speed of sound used to measure elasticity of materials
Researchers have devised a revolutionary new technique for measuring the microscopic elasticity of materials. Known as SRAS, the technology works by measuring the speed of sound across the material’s surface.
Human olfactory mucosa cell model opens a new perspective on Alzheimer’s disease
Researchers have developed and characterized a new cell model for Alzheimer’s disease that has wide utility for research and could prove useful in early diagnosis and testing of new therapies.
Psilocybin treatment for major depression effective for up to a year for most patients, study shows
Previous studies have shown that psychedelic treatment with psilocybin relieved major depressive disorder symptoms in adults for up to a month. Now, in a follow-up study of those participants, the researchers report that the substantial antidepressant …
Psyche, the iron giant of asteroids, may be less iron than researchers thought
Scientists have thought that the asteroid Psyche could be a big ball of pure iron, but new research suggests it’s likely harboring a hidden rocky component.
Lichens are in danger of losing the evolutionary race with climate change
To learn how lichens might be able to adapt to climate change, researchers examined the evolutionary history of the algae that’s a part of 7,000 kinds of lichens. By studying genetic relationships between algae and building a giant family tree to show …
Model of the human nose reveals first steps of SARS-CoV-2 and RSV infection
Researchers report the development of a versatile human nose organoid — a laboratory representation of the cells layering the inside of the nose where the first events of a natural viral infection take place — where they studied SARS-Cov-2 and RSV in…
Researchers use supercomputers for largest-ever turbulence simulations of its kind
Despite being among the most researched topics on supercomputers, a fundamental understanding of the effects of turbulent motion on fluid flows still eludes scientists. A new approach aims to change that.
Reacting to a changing environment involves inhibiting previous behavior
Researchers teamed up to understand the role of flexibility and inhibition in problem solving and how they relate to each other in a behaviorally flexible urban bird species, the great-tailed grackle. The researchers assessed the cognitive abilities of…
