For The Better

A new description of two well-preserved ancient fossil plant specimens in Washington state is prompting paleobotanists to rethink how plants might have been dispersed during the Late Cretaceous, between 66 and 100 million years ago.

It was a medical mystery: When scientists induced a particular genetic mutation in mouse eggs, the resulting embryos would all die in the womb within a week. And yet, people with the same troublesome gene are thriving.

Researchers have successfully used CRISPR-Cas9 to edit the genomes of the black-legged tick. To accomplish this feat, they developed an embryo injection protocol that overcame a major barrier in the field.

In a new, rare study of direct brain recordings in children and adolescents, scientists have discovered as brains mature, the precise ways by which two key memory regions in the brain communicate make us better at forming lasting memories. The findings…

A modeling study raises questions about how far droplets, like those that carry the virus that causes COVID-19, can travel before becoming harmless.

Carrying data streams using the terahertz (THz) spectral region could meet the ever-growing demand for unprecedented data transfer rates, i.e. terabits-per-second (Tb/s), since it offers a higher available bandwidth. However, it is extremely challengin…

Vaccine-associated myocarditis shows a similar injury pattern on cardiac MRI compared to other causes of myocarditis, but abnormalities are less severe, according to a new study.

Researchers have succeeded in developing a simple hydrocarbon molecule with a logic gate function, similar to that in transistors, in a single molecule. The discovery could make electric components on a molecular scale possible in the future.

Families of fish tend to share similar reactions to stressful situations, new research shows.

Antibodies elicited by COVID-19 vaccination become steadily more powerful for at least six months after vaccination, according to a new study.

Scientists reveal a way to make ammonia from its constituent molecules of nitrogen and hydrogen at ambient pressure.

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.

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.

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 …

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.

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 …

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…

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.
