A host of positive "tipping points" can spark rapid nature recovery, a leading expert says. Action to protect and restore nature must accelerate radically to meet global goals for 2030 and beyond. Writing in the journal Nature ...

How are bacterial pathogens able to effectively overcome plants' defense mechanisms? Researchers working with Professor Şuayb Üstün at Ruhr University Bochum, Germany, have found a surprising answer to this question: The ...

A new study by scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) has revealed significant cryptic diversity within two-toed sloths (Choloepus) in Amazonia, challenging the long-established ...

The Fe Kα line, or iron Kα line, is often used in astronomical research to understand the physical composition of astronomical objects. This line is produced when a K-shell electron of an iron ion in the photosphere—the gas ...

At first glance, the white plastic box with a bright orange floor looks like something for storing children's toys. However, the box isn't used to store Lego bricks; it contains real mice—with the aim of minimizing their ...

Storing genetic material as DNA or RNA is all well and good for life on Earth, but it would be entirely pointless if we couldn't do anything with it. To use our genetic blueprints, all organisms need to translate the message ...

Quartz crystals are difficult to knap due to size, hardness, and crystalline structure, making them a "low-quality" raw material. However, the Clovis people of North America sometimes made points and other tools from this ...

Astronomers, using the Atacama Large Millimeter/submillimeter Array (ALMA), have confirmed the existence of a close quasar pair housed in a pair of merging galaxies seen when the universe was less than a billion years old, ...

Generative artificial intelligence (AI) has transformed college writing. As paper drafts are increasingly co-written with AI, professors are left wondering not whether students are using AI, but how. A 2025 AI in Education ...

Using artificial intelligence, engineers at the University of California San Diego have developed a new way to watch the inner workings of living cells in real time. The process both captures images that are twice as sharp ...

For the first time, researchers have mapped how the boundaries of magnetic nanostructures behave on extremely short timescales. The work of physicist Johan Mentink of Radboud University shows that these boundaries are much ...

When humans are moving as a crowd, their movements tend to be highly coordinated, similarly to the collective motions of bird flocks or other groups of animals. These group behaviors can limit collisions in dynamic environments, ...
