For The Better

A new study examines ice cores from the summit of the highest tropical mountain in the world, and finds unique insight into the climate record of the Amazon Basin over the last six decades. 

Scientists mapped the gene regulatory networks responsible for progressive differentiation states of tumor-infiltrating T cells, using a technology known as single-cell CRISPR screening to knock out or genetically perturb multiple genes potentially inv…

Bacteria have an array of strategies to counter viral invasion, but how they first spot a stranger in their midst has long been a mystery.

A study found people who have a healthy weight use more energy during the day, when most people are active and eat, while those who have obesity spend more energy during the night, when most people sleep. Researchers also found that, during the day, th…

From invisible wafts of diesel exhaust to sun-choking plumes of orange smoke, air pollution is known to damage respiratory well-being. Now, research suggests another reason to hold our breath: Polluted air also may hurt reproductive health.   In a stud…

After a distant star’s explosive death, an active stellar corpse was the likely source of repeated energetic flares observed over several months — a phenomenon astronomers had never seen before, astronomers report.

For the first time, researchers have succeeded in printing a robotic hand with bones, ligaments and tendons made of different polymers using a new laser scanning technique. The new technology makes it possible to 3D print special plastics with elastic …

Newly discovered iron storage ‘ferrosomes’ inside the bacterium C. diff — the leading cause of hospital-acquired infections — are important for infection in an animal model and could offer new targets for antibacterial drugs. They also represent a ra…

Astronomers have used recent observations made with the James Webb Space Telescope to study the atmosphere of the nearby exoplanet WASP-107b. Peering deep into the fluffy atmosphere of WASP-107b they discovered not only water vapor and sulfur dioxide, …

A new technique offers a safe, reliable, and high-throughput way to dynamically characterize microscale metamaterials. The method could speed up the development of acoustic lenses, impact-resistant films, and other futuristic materials.

Seabirds roam far and wide in the Indian Ocean — so they need ocean-wide protection, new research shows.

Engineers have developed a high-throughput, multimaterial 3D inkjet printer that uses computer vision to rapidly and automatically control the amount of material being deposited during the printing process in real time. This enables the use of a wide r…
