Will ice floating in the Arctic Ocean move faster or slower over the coming decades? The answer to this question will tell us whether marine transportation can be expected to get more or less hazardous. It might also have important implications for the…

Researchers have developed a new catheter-based device that combines two powerful optical techniques to image the dangerous plaques that can build up inside the arteries that supply blood to the heart. By providing new details about plaque, the device …

Each year, approximately 2,000 people die annually of gallbladder cancer (GBC) in the U.S., with only one in five cases diagnosed at an early stage. With GBC rated as the first biliary tract cancer and the 17th most deadly cancer worldwide, pressing at…

Scientists recently combined satellite data, field observations and sophisticated numerical modeling to paint a picture of how 22.45 million square kilometers of the Arctic will change over the next 80 years. As expected, the overall region will be war…

A new fossil, named ‘Attenborough’s strange bird’ after naturalist and documentarian Sir David Attenborough, is the first of its kind to evolve a toothless beak. It’s from a branch of the bird family tree that went extinct in the mass extinction 66 mil…

While summer sea ice loss in the Arctic is inevitable, it can be reversed if the planet cools down, researchers say.

These reptiles move around tree trunks to seek warmth or shade. With trees disappearing, they would have trouble controlling their body temperature, a new study shows.

Green walls can strip pollution from the air — and some plants do it better than others, according to new research. Researchers planted 10 species on a custom-built 1.4m green wall.

Coronary artery calcium scoring with CT can identify symptomatic patients with a very low risk of heart attacks or strokes. Researchers said the findings may one day help some patients with stable chest pain avoid invasive coronary angiography.

Scientists have developed a novel triple-junction perovskite/Si tandem solar cell that can achieve a certified world-record power conversion efficiency of 27.1 per cent across a solar energy absorption area of 1 sq cm, representing the best-performing …

A collaborative team of researchers developed an implant coating triggering antibiotic release in response to bacterial infection.

People who experience sleep apnea may be more likely to also have memory or thinking problems, according to a preliminary study. The study shows a positive association but did not determine whether sleep apnea causes cognitive decline.

The James Webb Space Telescope is helping scientists uncover how planets form by advancing understanding of their birthplaces and the circumstellar disks surrounding young stars. Scientists have imaged winds from an old planet-forming disk (still very …

Scientists have pioneered a method for using semiconductor technology to manufacture processors that significantly enhance the efficiency of transmitting vast amounts of data across the globe.

Most of the sunlight reaching the Arctic Ocean is reflected to space by sea ice, effectively shielding ocean ecosystems from sunlight. As the Arctic sea ice continues its downward trend, larger areas of the ocean become exposed to sunlight for longer p…

Individual white storks incrementally straightened their migration routes to find more direct ways to move between destinations during the spring migration to summer breeding and nesting grounds, suggesting that experiential learning is an important pa…

In a new article, members of the Strategic Council of the National Academy of Sciences, Engineering, and Medicine examine what has happened to public confidence in science, why it has happened, and what can be done to elevate it. They say that while th…

A new study found differences at the cellular level of leaves from infected Beech trees — variations that may account for tree mortality.

Researchers have developed an artificial intelligence model that can accurately identify tumors and diseases in medical images. The tool draws a map to explain each diagnosis, helping doctors follow its line of reasoning, check for accuracy, and explai…

A recently published study that shows lactating mothers who get the COVID-19 booster pass along the antibodies to their children via their breast milk — and potentially protect babies too young to receive the vaccine.
