Medical Xpress / Astrocytes in the amygdala may play a key role in anxiety
In a study published in Neuron, Ciaran Murphy-Royal, researcher at the Center de recherche du Center hospitalier de l'Université de Montréal (CRCHUM), and his team show that astrocyte activity in the brain's fear center, ...
Tech Xplore / Video-based AI gives robots a visual imagination
In a major step toward more adaptable and intuitive machines, Kempner Institute Investigator Yilun Du and his collaborators have unveiled a new kind of artificial intelligence system that lets robots "envision" their actions ...
Phys.org / Ancient fish used their lungs to hear underwater, scientists reveal
How did ancient fish perceive their environment in the deep sea? An international team led by scientists from the Natural History Museum of Geneva (MHNG) and the University of Geneva (UNIGE) reveals that some coelacanths—fish ...
Phys.org / Light-activated nanoparticles trigger copper overload to kill cancer cells
Cuproptosis was discovered in 2022. It was a previously unknown type of cell death caused by an excess of copper. The research group led by Professor Johannes Karges at Ruhr University Bochum, Germany, used this mechanism ...
Medical Xpress / Targeted ultrasound may help the brain overcome fear more quickly
Neuroscientist Sjoerd Meijer of the Donders Institute at Radboud University has shown for the first time that targeted ultrasonic sound waves can help the brain overcome fear more quickly. These findings may open new avenues ...
Tech Xplore / Holographic storage approach packs more data into the same space by encoding three properties of light
Researchers have developed a holographic data storage approach that stores and retrieves information in three dimensions by combining three properties of light—amplitude, phase and polarization. By allowing more data to ...
Phys.org / Medieval DNA reveals trans-Saharan connections, rapid genetic mixing and leprosy in Islamic Ibiza
Medieval Ibiza was far from a quiet Mediterranean backwater. New DNA evidence shows that the island was part of a dynamic world linking Europe, North Africa and even the Sahel zone, south of Sahara. An international research ...
Tech Xplore / AI system learns to prevent warehouse robot traffic jams, boosting throughput 25%
Inside a giant autonomous warehouse, hundreds of robots dart down aisles as they collect and distribute items to fulfill a steady stream of customer orders. In this busy environment, even small traffic jams or minor collisions ...
Phys.org / Galactic warming: The 'car engine-like' effect heating our Milky Way
Our Milky Way's halo of hot gas is warmer to the "south" than the "north" because of an internal combustion engine-like effect that is compressing the gas like a piston, a new study has found. Computer simulations reveal ...
Medical Xpress / How the brain fine-tunes fear as threats fade
Researchers at Tulane University have identified brain circuits that help determine how fear responses change as perceived threats diminish, offering new insight into how the brain regulates defensive behavior and why those ...
Phys.org / Researchers create a three-nanometer single-layer UiO-66 MOF nanosheet
Metal-organic frameworks (MOFs) are porous structures composed of metal ions (or clusters) and organic linker molecules—much like a molecular scaffold. Thanks to their high porosity and large surface area, MOFs can store ...
Tech Xplore / ByteDance rolls out Seedance 2.0 globally, expanding AI video generation
Chinese artificial intelligence powerhouse and TikTok creator ByteDance has quietly rolled out its latest video generator Seedance 2.0 worldwide, while its US rival OpenAI called time on a similar product.
