Tech Xplore / Rule-breaking discovery reveals new way to strengthen metal in extreme conditions
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 ...
Medical Xpress / From the lab to the living room: Decoding Parkinson's patients' movements in the real world
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 ...
Tech Xplore / Midair haptics and levitation may get steadier with predictable ultrasonic airflow
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 ...
Phys.org / Ancestral motif enables broad DNA binding by NIN, a master regulator of rhizobial symbiosis
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 ...
Phys.org / Scientists decipher how two bacterial species cooperate to avoid being eaten
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 ...
Phys.org / X-ray platform images plasma instability for fusion energy and astrophysics
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 ...
Phys.org / New astronauts launch to the International Space Station after medical evacuation
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.
Tech Xplore / From flattery to debate: Training AI to mirror human reasoning
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 ...
Medical Xpress / False alarm in newborn screening: How zebrafish can prevent unnecessary spinal muscular atrophy therapies
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 ...
Tech Xplore / 'Dynamic plastic delocalization' can slow metal alloy cracking, engineers find
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 ...
Medical Xpress / How pancreatic cancer prepares the tumor environment: A possible biomarker for the earliest stage of development
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. ...
Tech Xplore / What is 'AI-induced psychosis'? Study explains how chatbots may sustain delusions
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 ...
