A recently published study brought together experts from the fields of oceanography, genetics, ecology, fisheries biology, and social sciences to develop unprecedented insights into the natural and commercial flow of fish.

Sinuous stellar jets meander lazily across a field of stars in new images. The gently curving stellar jets are the outflow from young stars, and astronomers suspect their sidewinding appearances are caused by the gravitational attraction of companion stars. These crystal-clear observations were made using the Gemini South telescope's adaptive optics system, which helps astronomers counteract the...

A study proposes that imbalanced forces and torques in the Earth-moon-sun system drive circulation of the whole mantle. The new analysis provides an alternative to the hypothesis that the movement of tectonic plates is related to convection currents in the Earth's mantle.

People vaccinated three times or vaccinated after an earlier COVID-19 infection had comparable neutralizing antibody activity to those with a breakthrough case, according to a new study.

Researchers have identified the highly prevalent, specific mutations that are causing the Omicron variant's high rate of infection. The findings help explain how the new variant can escape pre-existing antibodies present in the human body, either from vaccination or naturally from a recent COVID-19 infection.

A study has discovered that sufficient water flows during summer can be critical to a Chinook salmon population in the interior of British Columbia.

The energy systems that power our lives also produce wasted heat -- like heat that radiates off hot water pipes in buildings and exhaust pipes on vehicles. A new flexible thermoelectric generator can wrap around pipes and other hot surfaces and convert wasted heat into electricity more efficiently than previously possible, according to scientists.

Atom-level simulations reveal the reason iron rusts in supposedly 'inert' supercritical carbon dioxide fluid. Trace amounts of water can cause a reaction at the interface between iron and the fluid, prompting the formation of corrosive chemicals.

A research team has developed an optical computing system for AI and machine learning that not only mitigates the noise inherent to optical computing but actually uses some of it as input to help enhance the creative output of the artificial neural network within the system.

Mange has decimated the population of wild vicunas and guanacos in an Argentinian national park that was created to conserve them, according to a new study. The findings suggest domestic llamas introduced to the site may have been the source of the outbreak. Cascading consequences for local predator and scavenger species are expected.

A recent study found that about 63% of clinicians surveyed agree that immediate release of electronic medical records is more confusing than helpful to patients.

To understand the dynamics of emerging topics in science and medicine, researchers looked at researcher participation in articles containing emerging keywords over 50 years. They found that although more human resources are needed for publication, large research groups less frequently generate emerging topics. Moreover, expertise in certain topics has become important for generating emerging...

Researchers conducted single-cell gene expression analysis to uncover the effects of manipulation of the sensory cell regulator POU IV in the protovertebrate Ciona intestinalis. Alteration of POU IV expression led to the induction of cells with characteristics of multiple sensory cell types and cells that express a gene expression profile that has not been previously observed in Ciona...

Our brain maps out our body to facilitate accurate motor control. For a century, the body map has been thought to have applied to all types of motor actions. Now, a research group has revealed that the body relies on multiple maps based on the choice of motor system.

A research team has set a new record in the power conversion efficiency of solar cells made using perovskite and organic materials. Their latest work demonstrated a power conversion efficiency of 23.6%, approaching that of conventional silicon solar cells. This technological breakthrough paves the way for flexible, light-weight, low cost and ultra-thin photovoltaic cells for wide-ranging...

Researchers have developed a new control approach that enables a legged robot, called ANYmal, to move quickly and robustly over difficult terrain. Thanks to machine learning, the robot can combine its visual perception of the environment with its sense of touch for the first time.

Bumblebees are important pollinators because they pollinate many different plant species and are extremely resilient. They can still manage to fly at temperatures that are too cold for other pollinators. Like many other insects, they are in sharp decline. This makes it even more important to find out what bumblebees need to reproduce successfully. A team has shown that a diverse landscape and a...

Industry and private consumers alike depend on oil and gas pipelines that stretch thousands of kilometers underwater. It is not uncommon for these pipelines to become clogged with deposits. Until now, there have been few means of identifying the formation of plugs in-situ and non-destructively. Measurements now show that neutrons may provide the solution of choice.

In a win-win for commercial fisheries and marine wildlife, researchers have found that using lighted nets greatly reduced accidental bycatch of sharks, rays, sea turtles, and unwanted finfish.

Vortex dynamics simulations reveal reconnection, an important property linked with creation of turbulence cascade, fluid mixing, and aerodynamic noise generation. Turbulent pipe flow simulated at high Reynolds number of up to 5,000.

When 2-year old mice were studied after two months of progressive weighted wheel running, despite having no prior training, it was determined that they were the epigenetic age of mice eight weeks younger than sedentary mice of the same age.

Scientists have made a discovery about the properties of water that could provide an exciting addendum to a phenomenon established over two centuries ago. The discovery also holds interesting possibilities for cooling devices and processes in industrial applications using only the basic properties of water.

Of hospitalized children who tested or were presumed positive for SARS-CoV-2, 44 percent developed neurological symptoms, and these kids were more likely to require intensive care than their peers who didn't experience such symptoms, according to a new study.

In a 50-state survey-based study, adults with depressive symptoms were twice as likely to support misinformation about COVID-19 vaccines. People who endorsed false statements were half as likely to be vaccinated against COVID-19.
