Astronomers have, for the first time, found a source in the process of becoming a Little Red Dot, using the James Webb Space Telescope (JWST). Little Red Dots are likely early galaxies and some of the most intriguing objects ...

The effects of individual climate factors on ecosystems are usually considered in isolation. However, in reality, they occur simultaneously and influence each other. Increasing CO2 concentrations in the atmosphere contribute ...

Two diamonds formed 700 kilometers below the Earth's surface reveal a life-giving synchronicity between shifting continents and the cycling of phosphorus, a vital building block of DNA and cell membranes.

Indonesian astronomers have conducted a comprehensive study of an open cluster in the constellation Norma, known as NGC 6134. Results of the new study, available in a research paper published June 23 on the preprint server ...

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this ...

In 1562, Cardinal Giovanni de Medici, a scion of the dynastic family that dominated politics and banking in Tuscany during the Renaissance, died of malaria. Twenty-five years later, his older brother, Grand Duke Francesco ...

Plants need nitrogen to grow. Many legumes meet this need through a symbiotic relationship: They harbor bacteria that fix atmospheric nitrogen and make it available to the plant. Until now, it was largely unclear how a perennial ...

Astronomers have identified one of the most distant candidate galaxies known to leak ionizing radiation—the same kind of radiation thought to have transformed the early universe during the epoch of reionization.

A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells "walk" toward each other to close a wound for the first time. An associate professor of molecular genetics and cell biology ...

Researchers report some corn plants are genetically predisposed to develop longer, less constricted water-conducting tissues and deeper roots, which helps them deal with drought. That's the conclusion of a team led by Penn ...

A University at Buffalo-led team of researchers has developed a method for producing advanced nanoparticles that could accelerate the discovery of new materials for energy and electronic applications. The study, published ...

Every year, bacteria kill more than a million people worldwide through infections that no longer respond to antibiotics. In many cases, why those bacteria are so hard to stop comes down to their uniquely powerful structure.
