Medical Xpress / Predator-like scent activates an anxiety-related brain circuit in mice
Anxiety disorders are some of the most common psychiatric conditions, estimated to affect around 4.4% of people worldwide, according to the World Health Organization. While neuroscientists have been studying these disorders ...
Tech Xplore / Robots recognize the shape of an arena by messaging each other
Humans can create loose maps of environments they are exploring in their minds, using their senses and navigation skills. Many robots, on the other hand, rely on set maps of known environments or new maps produced using data ...
Tech Xplore / AI models can answer differently when told they are being watched
Large language models (LLMs), the AI systems underpinning the functioning of ChatGPT, Gemini and other similar platforms, are now widely used worldwide. While the responses provided by these models can be useful in many situations, ...
Medical Xpress / How the brain rapidly learns to interpret ambiguous images
Both humans and image recognition algorithms can take time to identify the objects and scenes depicted in some images. Emblematic examples of this phenomenon are Mooney images, pictures that are intentionally reduced to patches ...
Phys.org / Wider daily temperature ranges linked to stronger fevers in amphibians and reptiles
When amphibians and reptiles get an infection, they sometimes raise their body temperature above its usual level by moving to a warmer environment. This well-documented behavioral response is known as behavioral fever.
Medical Xpress / Brain imaging uncovers a shared memory network linked to mild cognitive impairment
As they age, many individuals can struggle to remember recent events or what they meant to say next during a conversation, while also frequently losing or misplacing objects. In some cases, cognitive tests detect these memory ...
Phys.org / The tropics weren't always the most diverse marine environments, study finds
Today, tropical waters typically host a wider range of marine animals than polar waters. This decline in marine biodiversity from the equator toward the North and South poles is known as the latitudinal diversity gradient.
Phys.org / Deeper dives are linked to longer surface recovery in sea lions
Sea lions, marine mammals belonging to the eared seal family, have to dive to search for food and other resources. Between dives, however, they return to the surface to breathe and recover.
Tech Xplore / Extra robotic thumb lets wearers complete two-handed tasks with one hand
To complete many everyday tasks and chores, humans typically use both of their hands. For instance, when opening a bottle, they use one hand to hold the bottle and the other to twist its cap. Researchers at the University ...
Phys.org / Optical experiment demonstrates the strong Mpemba effect in a single qubit
Typically, after a physical system is disturbed, it can gradually return toward a state of thermal equilibrium by exchanging heat with its surroundings. Thermal equilibrium is a state in which there is no net transfer of ...
Tech Xplore / Team unlocks large-scale Fourier transforms for analog in-memory computing
Fourier transforms are mathematical calculations that can be used to identify the frequencies that make up a signal and shed light on their individual contributions. These transforms have been used, for example, to unveil ...
Medical Xpress / Microglia drive excessive iron transfer in Parkinson's disease models
Parkinson's disease (PD) is a neurodegenerative condition associated with worsening tremors, slowed movements, changes in walking and speech, muscle rigidity and postural instability. Many of its symptoms are associated with ...
Medical Xpress / How neurons in the hippocampus separate different aspects of experiences
When remembering an experience, people often recall not just where it happened, but also its timing and how it unfolded over time. This helps them to recall sequences of events and associations that can guide their actions ...
Phys.org / Call adjustments help bats keep their echolocation signals distinct, study finds
Bats can produce ultrasonic pulses with high frequencies between 20,000 and 120,000 hertz, which are inaudible to humans. The sound waves they produce travel forward, hitting nearby objects and bouncing back in the form of ...
Medical Xpress / Slow brain rhythms do more than reflect sleep—they help trigger it, fruit fly study suggests
For most animals, the need for sleep gradually increases during waking hours and then decreases while sleeping. In neuroscience, this accumulating need to sleep is known as sleep pressure.
