Medical Xpress / Smooth-gradient fMRI technique could improve brain mapping during behavior
Neuroscientists and medical researchers now have a wide range of imaging techniques to study the brain and its activity. One of the most widely used is functional magnetic resonance imaging (fMRI), a noninvasive technique ...
Phys.org / Caffeine pollution could disrupt crustacean defenses against predators
While most people are aware of how plastic, arsenic and various industrial chemicals can pollute bodies of water, the effects of caffeine on freshwater environments remain largely unknown. Nonetheless, traces of caffeine, ...
Medical Xpress / Stable frontal signals, flexible hippocampal ones: How the brain preserves context as goals change
While humans are completing a task, they can temporarily store information in their minds while also manipulating and adapting it based on changing circumstances. To support this capability, known as working memory, the brain ...
Tech Xplore / How AI models decide not to answer a question
Large language models (LLMs), the artificial intelligence (AI) systems supporting the functioning of ChatGPT, Gemini and similar conversational platforms, are often expected to answer queries, generate texts for specific ...
Tech Xplore / AI imagines a harsher social world, expecting punishment where people expect inaction
Artificial intelligence (AI) systems, particularly the large language models (LLMs) that underpin ChatGPT and similar platforms, are remarkably skilled at answering queries about a wide range of topics. However, the extent ...
Phys.org / For many group-living females, breeding and raising young are shared endeavors
Some female animals living in groups raise offspring that are not their own, sometimes without reproducing themselves. While the behavior of cooperatively breeding species is well documented, some aspects remain poorly understood.
Medical Xpress / Chromatin protein DAXX may help preserve brain immune cells during aging
As humans get older, their brains undergo various changes that can affect mental functions. The cells known to be affected by aging include microglia, the primary immune cells in the brain and spinal cord, which help eliminate ...
Phys.org / AI updates can sometimes feel like breakups or losses, study finds
Artificial intelligence systems, particularly those powered by large language models and designed to communicate with users on a one-to-one basis, are increasingly used worldwide. Some of these systems, such as Replika, are ...
Phys.org / Gravitational-wave analysis narrows the search for black hole impostors
Black holes are regions of spacetime where gravity is so strong that nothing, not even light, can escape. When two black holes orbit each other and merge, they produce gravitational waves (i.e., ripples in spacetime) that ...
Phys.org / New analysis reconstructs the dawn of dinosaurs and other reptiles
About 252 million years ago, at the end of the Permian Period, a large proportion of species on Earth rapidly became extinct. After this mass extinction, many groups of organisms began to recover, while reptiles known as ...
Phys.org / Spinons may help electrons pair along stripes in some superconductors
Superconductors are materials that carry electricity with zero resistance below specific temperatures. Many of these materials become superconducting at very low temperatures, yet some enter superconducting phases at higher ...
Tech Xplore / Humanoid robot learns to sprint and perform spin kicks using AI trained on human motion data
Humanoid robots, robotic systems with body shapes and limbs resembling those of humans, could potentially assist people with manual tasks in various real-world settings. So far, however, most of these robots can reliably ...
Tech Xplore / AI controller translates VR, video and language commands into humanoid robot actions
Humanoid robots, robotic systems with limbs and body structures that resemble those of humans, could tackle various manual tasks in homes, workspaces and other settings. Yet teaching these robots to reliably perform different ...
Phys.org / Could quantum protocols make electronic voting more secure?
Electronic voting, the use of electronic systems to cast, record or count votes, could potentially simplify the process of electing new political leaders or other representatives. While some countries have already started ...
Medical Xpress / How the mouse brain learns from a single experience
Sometimes, even a single experience can be highly impactful, prompting humans and other animals to change their behavior or influencing their future choices. The formation of influential memories from a single, brief experience ...
