When it comes to treating heart attacks, U.S. hospitals may have the latest tech and low readmission rates, but the country’s mortality rate is one of the highest among the nations included in a new study. The study found substantial differences in car…

Scar-like cells that make up a sizable portion of malignant pancreatic tumors and shield these cancers from immune attack are derived from mesothelial cells that line tissues and organs, a new study suggests. The findings could offer a new strategy to …

Holding the right material at the right angle, researchers have discovered a strategy to switch the magnetization in thin layers of a ferromagnet — a technique that could eventually lead to the development of more energy-efficient magnetic memory devi…

Researchers are applying a form of artificial intelligence (AI) — previously used to analyze how National Basketball Association (NBA) players move their bodies — to now help scientists develop new drug therapies for medical treatments targeting canc…

A modified PRS increases predictive accuracy by integrating data from diverse populations.

Photonics researchers have created a potentially disruptive technology for the ultraviolet optics market. Solid-state ‘metalens’ transform long-wave UV into focused ‘vacuum UV,’ a type of light used in semiconductor manufacturing that is costly, in par…

Researchers used an Artificial Intelligence Materials Selection framework (AIMS) to discover a new shape memory alloy. The shape memory alloy showed the highest efficiency during operation achieved thus far for nickel-titanium-based materials. In addit…

A new study reports a 50 to 60 percent lower risk of colorectal cancer (CRC) among women who started endoscopy screening at age 45 compared to those who had not undergone screening at all.

Agricultural water scarcity is expected to increase in more than 80% of the world’s croplands by 2050, according to a new study.

In a study that followed hundreds of mice over their lifespans, calorie restriction combined with time-restricted eating boosted longevity.

Whether it’s making rash decisions or feeling grumpy, hunger can make us think and act differently — ‘hangry,’ even. But little is known about how hunger signals in the gut communicate with the brain to change behavior. Now, scientists are using worms…

Researchers have uncovered how signals from a group of neurons in the brain’s frontal lobe simultaneously give humans the flexibility to learn new tasks — and the focus to develop highly specific skills.

Researchers have been able to study the surface of a copper-zinc catalyst when carbon dioxide is reduced to methanol. A better knowledge of the catalytic process and the possibility of finding even more efficient materials opens the door for a green tr…

A team has mapped a huge, actively circulating groundwater system in deep sediments in West Antarctica. They say such systems, probably common in Antarctica, may have as-yet unknown implications for how the frozen continent reacts to, or possibly even …

The world’s smallest marine mammal — the critically endangered vaquita porpoise, which lives only in Mexico’s Sea of Cortez — is believed to have only 10 living members, if that, of the species. The vaquita is widely thought to be on the verge of ext…

Researchers reveal a mechanism by which oxybenzone, a common sunscreen component, damages corals. The surprising findings could help guide the development and marketing of effective, coral-safe sunscreens.

In a prospective study of young, lean adults, PET/CT imaging revealed that higher levels of active brown adipose tissue (also known as ‘brown fat’) are more prevalent in individuals who exhibit very early indications of metabolic disorders. The study s…

Bicycle sharing is an attractive zero-carbon transportation option for a world that is being increasingly disrupted by climate change. But bikes need to be restored at bike ports every now and then. Calculating the optimal way to restore bicycles is ti…

The human body consists of trillions of cells that constantly communicate with each other. A central role in this communication process is played by receptor proteins on the cell surface. Since they often serve as drug targets, they have been the subje…

It’s not unheard of to find a surviving star at the scene of a titanic supernova explosion, which would be expected to obliterate everything around it, but new research has provided a long-awaited clue to a specific type of stellar death. In some super…
