Astronomers have revealed new evidence about the properties of the giant bubbles of high-energy gas that extend far above and below the Milky Way galaxy's center.

For millions of people with seasonal allergies, springtime means runny noses, excessive sneezes and itchy eyes. And, as with many things, climate change appears to be making allergy season even worse. Researchers have now shown that common allergen-producing plants ryegrass and ragweed emit more smaller, 'subpollen particles' (SPPs) than once thought, yet climate would likely be most affected by...

Discarded or drifting in the ocean, plastic debris can accumulate on the water's surface, forming floating islands of garbage. Although it's harder to spot, researchers suspect a significant amount also sinks. In a new study in ACS' Environmental Science & Technology, one team used computer modeling to study how far bits of lightweight plastic travel when falling into the Mediterranean Sea. Their...

A team of researchers has improved a new generation of organic-inorganic hybrid materials that can improve image quality in X-ray machines, CT scans and other radiation detection and imaging technologies.

Astronomers used NASA's James Webb Space Telescope to image the warm dust around a nearby young star, Fomalhaut, in order to study the first asteroid belt ever seen outside of our solar system in infrared light. But to their surprise, the dusty structures are much more complex than the asteroid and Kuiper dust belts of our solar system. Overall, there are three nested belts extending out to 14...

Birds across the Americas are getting smaller and longer-winged as the world warms, and the smallest-bodied species are changing the fastest.

Imagine a cocktail party full of 3D-printed, humanoid robots listening and talking to each other. That seemingly sci-fi scene is the goal of an augmented listening laboratory. With precise control over the simulated subjects, the researchers can adjust the parameters of the experiment and even set the machines in motion to simulate neck movements.

A new study provides the first observational evidence of the stabilization of the anti-cyclonic Beaufort Gyre, which is the dominant circulation of the Canada Basin and the largest freshwater reservoir in the Arctic Ocean.

A limited menu of prey may weave a tangled food web by emboldening wolf spiders of multiple species to dine on each other and even cannibalize their own, says a new study.

Scientists find an auto-signaling mechanism driving the T cell anti-tumor response; findings may inspire new cancer therapeutics and biomarkers.

Scientists have identified new genetic risk factors for two types of non-Alzheimer's dementia. These findings detail how researchers identified large-scale DNA changes, known as structural variants, by analyzing thousands of DNA samples. The team discovered several structural variants that could be risk factors Lewy body dementia (LBD) and frontotemporal dementia (FTD).

New research shows the use of a new cellular probe helped discover new findings about certain cellular processes.

A new study finds that incoming students who participated in an online belonging exercise completed their first year as full-time college students at a higher rate than their peers, but only when their institution had strong strategies and resources in place to support diverse students' belonging.

A new study found that air pollution from the oil and gas sector in the United States has substantial adverse impacts on air quality, human health, and health costs. The findings show that the pollutants nitrogen oxide (NO2), fine particulate matter (PM2.5) and ozone (O3) from U.S. oil and gas production contributed to 7,500 excess deaths, 410,000 asthma attacks, and 2,200 new cases of childhood...

Using a new technique, researchers have shown that they can map interactions between gene promoters and enhancers with 100 times higher resolution than has previously been possible.

Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in free space. These are the first to demonstrate simultaneous control of all four optical degrees of freedom. Because they're so thin, transparent, and compatible with photonic integrated circuits, they...

Scientists find new route in bacteria to decarbonize industry. The discovery could reduce greenhouse gas emissions from the manufacturing of fuels, drugs, and chemicals. A research team has engineered bacteria to produce new-to-nature carbon products that could provide a powerful route to sustainable biochemicals.

Researchers are creating a high-resolution atlas that depicts the development of the human retina. One technique they use is a new method that allows them to visualize more than 50 proteins simultaneously. The atlas helps scientists to better understand diseases.

Researchers have developed a zebrafish model that provides new insight into how the brain acquires essential omega-3 fatty acids, including docosahexaenoic acid (DHA) and linolenic acid (ALA), with the potential to improve understanding of lipid transport across the blood-brain barrier and of disruptions in this process that can lead to birth defects or neurological conditions.

After a stroke, physical activity can be pivotal to successful recovery. People who spend four hours a week exercising after their stroke achieve better functional recovery within six months than those who do not, a new study shows.

Depression is a condition affecting millions across the globe. However, efficient drugs with minimal adverse effects are scarce. Now, researchers have reported how KNT-127, a delta opioid receptor agonist, quickly and efficiently reduces classic parameters of depression in a mouse model. This anti-depressant agent exhibits the dual nature of being a stress reliever and an anti-depressant and could...

Humans inherited genetic material from Neanderthals that affects the shape of our noses, finds a new study.

Quantum dots in semiconductors such as silicon or gallium arsenide have long been considered hot candidates for hosting quantum bits in future quantum processors. Scientists have now shown that bilayer graphene has even more to offer here than other materials. The double quantum dots they have created are characterized by a nearly perfect electron-hole-symmetry that allows a robust read-out...

As AI becomes increasingly realistic, our trust in those with whom we communicate may be compromised. Researchers at the University of Gothenburg have examined how advanced AI systems impact our trust in the individuals we interact with.
