There's a reason why blacksmiths fire metals before hammering them. Heat always softens metal, making it more malleable and easier to reshape. Or does it? In a surprising new study, Northwestern University engineers discovered ...

Scientists have traditionally studied how the brain controls movement by asking patients to perform structured tasks while connected to multiple sensors in a lab. While these studies have provided important insights, these ...

Acoustic streaming generated by airborne ultrasonic phased arrays plays a critical role in the performance of advanced ultrasonic technologies, including midair haptic feedback, odor delivery, and acoustic levitation. Researchers ...

Researchers at University of Tsukuba have uncovered a master transcriptional regulator that controls rhizobial symbiosis between plants and nitrogen-fixing bacteria. By identifying an amino acid motif that emerged before ...

Back in 2021, Pierre Stallforth and his team at the Leibniz-Institute for Natural Product Research and Infection Biology (Leibniz-HKI) showed that bacteria of the genera Pseudomonas and Paenibacillus join forces to protect ...

Harnessing the power of the sun holds the promise of providing future societies with energy abundance. To make this a reality, fusion researchers need to address many technological challenges. For example, fusion reactions ...

A new crew rocketed toward the International Space Station on Friday to replace the astronauts who returned to Earth early in NASA's first medical evacuation.

Generative artificial intelligence systems often work in agreement, complimenting the user in its response. But human interactions aren't typically built on flattery. To help strengthen these conversations, researchers in ...

A positive newborn screening for spinal muscular atrophy (SMA) is currently considered a medical emergency. Without early treatment, severe disability or death in infancy are likely. However, research findings from Germany ...

Metal alloys crack and fail through a mechanism called "fatigue" when repeatedly loaded and strained. While it is well known how to design alloys to withstand static loads and pressures, it is very difficult to design resistance ...

Even before a tumor in the pancreas becomes discernible, an activated cancer gene actively remodels its future environment and creates an inflammatory and immune-defensive microenvironment in which the carcinoma can grow. ...

When generative AI systems produce false information, this is often framed as AI "hallucinating at us"—generating errors that we might mistakenly accept as true. But a new study argues we should pay attention to a more ...
