A novel technique for studying vortices in quantum fluids has been developed by physicists. Turbulence in quantum systems, for example in superfluid helium 4, takes place on microscopic scales, and so far scientists have not had tools with sufficient precision to probe eddies this small. But now the team, working at temperature of a few thousandths of a degree above absolute zero, has harnessed...

Clavelina oblonga, an invasive marine fouling species, not only reduces diversity in communities it invades, it also interferes in their recovery following natural disasters - a process known as 'succession.'

Researchers have used a mouse model to demonstrate the pivotal role of cholesterol in CIPN, and proposed a novel therapeutic approach to reverse it.

New observations reveal that Mars could still be volcanically active, raising the possibility for habitable conditions in the near surface of Mars in recent history. Ongoing research investigates the possibility that the most recent volcanic activity on Mars, which occurred about 50,000 years ago, might have been triggered by a nearby asteroid impact that happened around the same time.

As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, researchers have designed a way to make the...

Poor air quality caused by food production in the U.S. is estimated to result in 16,000 deaths annually, 80% of which are related to animal production, according to a new study. The study also shows how improving animal and crop management practices, as well as how eating more plant-rich diets, can substantially reduce mortality from food-related air pollution.

Researchers have devised a novel technique to 'flip' the optical wavefront of an image for both polarizations simultaneously, so that it can be transmitted through a multimode fiber without distortion.

Engineers develop a new version of their wireless implant that allows for multiple stimulators to be programmed and magnetically powered from a single transmitter outside the body. The implants could be used to treat spinal cord injuries or as pacemakers.

Twins produce fewer gestures and gesture to fewer objects than other children. Language use also lags for twins, and language -- but not gesture -- is also affected by sex, with girls performing better than boys.

Geoscientists have found that shallow wastewater injection -- not deep wastewater injections -- can drive widespread deep earthquake activity in unconventional oil and gas production fields.

A new survey found that the future of hunting in the United States might look different than it has in the past.

Scientists have carried out a study investigating whether deep neural networks can represent associations between gene expression, histology, and CT-derived image features. They found that the network could not only reproduce previously reported associations but also identify new ones.

Forests' ability to adapt to the disruptions wrought by climate change may depend, in part, on the eddies and swirls of global wind currents, suggests a new study. The study compared global wind patterns with previously published genetic data of nearly 100 tree and shrub species collected from forests around the world, finding significant correlations between wind speed and direction and genetic...

By engineering a short chunk of protein, or peptide, that can prevent the attachment of human parainfluenza viruses to cells, researchers have improved a method in rodent models intended to help keep children healthy.

Single-photon imaging is the future of high-speed digital photography and vastly surpasses conventional cameras in low-light conditions. However, fixing the blurring caused by the motion of independent objects remains challenging. Recently, researchers at developed an innovative de-blurring approach that accurately estimates the motion of individual objects and adjusts the final image accordingly....

Scientists are researching a new COVID-19 vaccine that would target only a small portion of the virus's spike protein. The vaccine has shown promise in laboratory experiments, and more vaccines could be necessary in the years ahead as additional SARS-CoV-2 variants emerge.

Scientists have found that many esophageal cancers turn on ancient viral DNA embedded in our genome, a finding that could lead to improvements in immunotherapy.

How a planet comes together has implications for whether it captures and retains the volatile elements, including nitrogen, carbon and water, that eventually give rise to life, according to scientists.

NASA's Voyager I spacecraft has long since zipped past the edge of the solar system through the heliopause - the solar system's border with interstellar space - into the interstellar medium. Now, its instruments have detected the constant drone of interstellar gas (plasma waves).

The relationship a dog has with its owner is related to its stress level. This is the conclusion of a newly published study. The results also suggest that the link between stress and the owner's personality traits differs between dog breeds.

A potential new vaccine has proven effective in protecting monkeys and mice from a variety of coronavirus infections -- including SARS-CoV-2 as well as the original SARS-CoV-1 and related bat coronaviruses that could potentially cause the next pandemic.

After infection, SARS-CoV-2 causes the host cell to produce new virus particles and suppresses host cell defence mechanisms. Virus protein nsP3 plays a central role in the latter process. Using structural analyses, researchers have now discovered that a decomposition product of the remdesivir binds to nsP3. This previously unknown effective mechanism may be important for the development of new...

Captive pelicans that are free to choose their own friendships are more likely to breed successfully on repeated occasions, new research suggests.

MRSA skin infections are often treated with intravenous injection of antibiotics, which can cause significant side effects and promote the development of resistant bacterial strains. To solve these problems, researchers are developing a microneedle patch that delivers antibiotics directly into the affected skin area. New results show that the microneedle patch effectively reduces MRSA bacteria in...
