Our eyes move three times per second. Every time we move our eyes, the world in front of us flies across the retina at the back of our eyes, dramatically shifting the image the eyes send to the brain; yet, as far as we can tell, nothing appears to move. A new study provides new insight into this process known as "visual stabilization". The results are published in the Proceedings of the National Academy of Sciences.

CLEVELAND: New findings from Cleveland Clinic researchers show for the first time that the gut microbiome impacts stroke severity and functional impairment following stroke. The results, published in Cell Host & Microbe, lay the groundwork for potential new interventions to help treat or prevent stroke. The research was led by Weifei Zhu, Ph.D., and Stanley Hazen, M.D., Ph.D., of Cleveland Clinic's Lerner Research Institute.

Immune cells that normally repair tissues in the body can be fooled by tumors when cancer starts forming in the lungs and instead help the tumor become invasive, according to a surprising discovery reported by Mount Sinai scientists in Nature in June.

While air-borne droplets bounce off commonly used plexiglass dividers, they stick to surfaces coated with the new material, then get absorbed and dry up.

European scientists propose a personalized protocol for optimizing stimulation of optic nerve fibers, for the blind, which takes into account feedback from the viewer's brain. The protocol has been tested on artificial neural networks known to simulate the physiology of the entire visual system, from the eye to the visual cortex. The stimulation protocol will be tested in clinical trials with partners in Rome.

A ball of 4,000-year-old hair frozen in time tangled around a whalebone comb led to the first ever reconstruction of an ancient human genome a decade ago. The hair, which was preserved in arctic permafrost in Greenland, was collected in the 1980s. It wasn't until 2010 that evolutionary biologist Professor Eske Willerslev was able to use pioneering shotgun DNA sequencing to reconstruct the genetic history of the hair. It sparked a 'decade of discovery.'

What The Study Did:Â This study demonstrated an association between receiving the mRNA-1273 (Moderna) vaccine and a reduction in SARS-CoV-2 infection in health care workers beginning eight days after the first dose.

Survival among people with early-onset (diagnosed before age 50) colorectal cancer compared with later-onset colorectal cancer (diagnosed at ages 51 through 55) was compared using data from the National Cancer Database.

Researchers examined to what extent cannabis use is associated with thickness in brain areas measured by magnetic resonance imaging in a study of adolescents.

A new study led by researchers from McGill University and INRAE found that between 51-60% of the 64 million kilometres of rivers and streams on Earth that they investigated stop flowing periodically, or run dry for part of the year. It is the first-ever empirically grounded effort to quantify the global distribution of non-perennial rivers and streams. The research, which was published today in Nature, calls for a paradigm shift in river science and management.

When Betelgeuse, a bright orange star in the constellation of Orion, became visibly darker in late 2019 and early 2020, the astronomy community was puzzled. A team of astronomers have now published new images of the star's surface, taken using the European Southern Observatory's VLT, that clearly show how its brightness changed. The new research reveals that the star was partially concealed by a cloud of dust, a discovery that solves the mystery of the "Great Dimming" of Betelgeuse.

It is possible to re-create a bird's song by reading only its brain activity, shows a first proof-of-concept study from the University of California San Diego. The researchers were able to reproduce the songbird's complex vocalizations down to the pitch, volume and timbre of the original. The study is a first step towards developing vocal prostheses for humans who have lost the ability to speak.

Quantum computers could outperform classical computers at many tasks, but only if the errors that are an inevitable part of computational tasks are isolated rather than widespread events. Now, researchers at the University of Wisconsin-Madison have found evidence that errors are correlated across an entire superconducting quantum computing chip -- highlighting a problem that must be acknowledged and addressed in the quest for fault-tolerant quantum computers.

When Betelgeuse, a bright orange star in the constellation of Orion, lost more than two-thirds of its brightness in late 2019 and early 2020, astronomers were puzzled.

A University of Iowa team has found that babies twitch during a sleep stage called quiet sleep, not just during REM sleep. The results may show there's more communication between snoozing infants' brains and motor systems than previously known. Results appear in the journal Current Biology.

Small modeling errors may accumulate faster than previously expected when physicists combine multiple gravitational wave events (such as colliding black holes) to test Albert Einstein's theory of general relativity, suggest researchers at the University of Birmingham in the United Kingdom. The findings appear June 16 in the journal iScience.

By repurposing common ingredients in hair conditioner, scientists have designed an inexpensive, transparent coating that can turn surfaces like windows and ceilings into glue pads to trap airborne aerosol droplets. This new strategy is described June 16 in the journal Chem.

Some of the world's most vulnerable cities suffer disproportionate economic losses because of the health consequences of in-car air pollution, finds a new study.

Fundamental signaling pathway is crucial for longevity.

Researchers from the University of Kent's School of Psychology have found that when people are presented with the idea of a COVID-19 'immunity passport,' they show less willingness to follow social distancing and face covering guidelines.
