A new study reveals how a remarkable group of plants on the Galápagos Islands developed their diverse leaf shapes—offering unique insight into evolution at the genetic level. A large international team of researchers has ...

MIT researchers discovered a paradoxical phenomenon in optical physics that could enable a new bioimaging method that's faster and higher-resolution than existing technology. They discovered that, under the right conditions, ...

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 ...

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 ...

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 ...

Human languages are known to have grown and changed considerably over the course of history, often reflecting technological, cultural, and societal shifts. Studying the evolution of languages can thus offer valuable insight ...

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, ...

A detector buried deep in Antarctic ice has captured the first experimental evidence of a predicted but never-before-seen phenomenon: radio pulses generated when high-energy cosmic rays slam into the ice sheet and trigger ...

The internet and social media platforms have given rise to a rising wave of misinformation, with many users now posting fake news, AI-generated photos or videos and other types of misleading content online. Over the past ...

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 ...
