Climate observers have long tied the strength of a major ocean current to water temperatures in the so-called "cold blob" in the North Atlantic Ocean. The 965,000-square-mile (2.5 million square kilometers) area south and southeast of Greenland cooled by as much as 1.8 degrees Fahrenheit over the past century as other ocean waters warmed.
Our noses are home to many different species of bacteria living side by side. One of them may be S. aureus. Many people carry this bacterium without knowing it, although it can cause serious infections. Why S. aureus colonizes some people persistently but not others remains only partly understood.
A study led by researchers from the Germans Trias i Pujol Research Institute (IGTP) and the Blood and Tissue Bank (BST) has developed and validated a manufacturing platform for extracellular vesicles that meets pharmaceutical quality requirements, marking a key step toward their clinical application.
It's no secret that American politics is dominated by older politicians. When 81-year-old Joe Biden withdrew from the 2024 presidential race amid concerns about his age, it was the then-78-year-old Donald Trump who ultimately entered the White House. The median age in the House of Representatives and the Senate was 58 and 65, respectively, while the average American was just 39 years old.
Modern space exploration hasn't quite reached "Star Trek" levels of boldly going where no one has gone before. But if, like the denizens of the USS Enterprise, astronauts one day want to land on an uncharted planet, they'd first want to know what's on—and under—the surface.
Tiny skeletal plates recovered beside fossil whale bones in southern Denmark offer a rare glimpse of life around a whale carcass approximately 9.5 million years ago. Researchers have identified a new species of brittle star, Ophiura huebnerjenseni, from the Gram Clay Pit and suggest it represents the first fossil record of brittle stars associated with a whale fall.
The kids are not all right on the future. For the first time in the 26-year history of the Harvard Youth Poll, more respondents expect to be worse off financially than their parents (27%) than better off (25%).
The Southern Ocean may seem far removed from the North Pacific or the Gulf of Maine, but its waters are linked to all the world's major ocean basins through a vast circulation system.
Chinese researchers have developed a new way to improve sodium–sulfur battery performance by changing the atomic structure of a catalyst. Led by professors Wang Hui and Zheng Fangcai from the High Magnetic Field Laboratory at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, the study is published in Angewandte Chemie.
Imagine shuffling a deck of cards where some of the cards are fading just because of the way they interact with the external environment as you shuffle them. Your job is to figure out the interplay between the shuffling, or "imposed randomness," due to the way you shuffle your cards and how that relates to the fading as cards are exposed to the external environment.
Waste dumped into the Tijuana River can travel seven times farther than expected before becoming airborne and affecting San Diego's air, at least 20 miles (32 kilometers) from its source, according to new UC Riverside research.
The new study by Newcastle University and the International Union for Conservation of Nature (IUCN) offers a practical roadmap for tracking progress toward halting species extinctions by 2050. It guides users from understanding where species are most at risk in a given area, through taking action to reduce species threats, to measuring the real-world impact of conservation efforts on reducing species extinction risk over time.
