Phys.org / Why some water fleas suddenly grow helmets: Key receptors reveal how predator warnings trigger defense
Daphnia, commonly known as water fleas, are tiny crustaceans that live in freshwater ponds and lakes. When they sense predators in their surroundings, these small organisms can swiftly move away or adapt their body shape, ...
Medical Xpress / Hippocampal ripples and replay reveal how brain recombines past knowledge for flexible planning
When facing new situations or problems, humans typically rely on knowledge they acquired in the past. Specifically, neuroscience studies suggest that the brain reorganizes past experiences and previously acquired knowledge, ...
Medical Xpress / Inside the cerebellum, unique neurons predict the timing of future events
Humans and other animals constantly make predictions about future events based on previous experiences and their perceptions of the surrounding environment. This predictive process is described by a mathematical framework ...
Medical Xpress / How the brain switches between older and newer memories
As humans and other animals experience new things, their brains continuously update their memory of past events. These updates allow them to adapt to changing environments, all while preserving older memories that could still ...
Tech Xplore / Signal-folding design helps neuromorphic chip slash AI energy use
Artificial intelligence systems, such as large language models (LLMs) and convolutional neural networks (CNNs), can analyze large amounts of data and rapidly generate desired content or identify meaningful patterns. However, ...
Phys.org / Strange 500-million-year-old marine fossils reveal a feeding strategy that still shapes oceans today
More than 500 million years ago, during what is known as the Cambrian period, the seas and oceans on Earth were filled with a myriad of marine animals, many of which have now become extinct. This evolutionary burst in new ...
Phys.org / Atomic bands in two transition metal dichalcogenides hint at long-theorized quantum state
Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an unusual insulating state dubbed obstructed atomic insulator (OAI), in which electrons are localized inside ...
Medical Xpress / Fear memories fade faster when brain immune cells engage key neurons, study suggests
Post-traumatic stress disorder (PTSD) and anxiety disorders are often characterized by fearful responses in specific situations that the mind learns to view as threatening. These fearful responses typically emerge following ...
Phys.org / Engineered exosomes reverse sleep deprivation brain damage in mice
Sleep is a vital physiological process that allows humans and other animals to restore both the mind and body, while also consolidating memories, clearing out toxins and regulating their metabolism. Several past studies showed ...
Phys.org / Work songs can improve team coordination, study finds
Work songs, musical pieces designed to be performed or sung while working, have been widely documented across various cultures and in different historical periods. For instance, people in different nations have been known ...
Tech Xplore / 'Touch dreaming' helps humanoid robots handle five tricky tasks with 90.9% higher success
Humanoid robots, robotic systems with a body structure that resembles that of humans, could soon assist humans with various tasks in household environments, manufacturing sites, hospitals and other settings. While some humanoid ...
Tech Xplore / Quantum dot emitter delivers near-identical telecom photons at 40 million per second
Quantum technologies, devices that perform specific functions leveraging quantum mechanical effects, could soon outperform their classical counterparts on some tasks. Quantum emitters, devices that release individual particles ...
Medical Xpress / How the brain decides which memories belong together could reshape schizophrenia research
Our memories of past events are typically not isolated, but they are linked to other related memories. This ability to establish connections between related memories is highly advantageous, as it helps us to recognize familiar ...
Phys.org / When uncertainty spikes, chasing rewards backfires and a more informed strategy pulls ahead
Humans and other animals are constantly required to make decisions under uncertain conditions or while in rapidly changing environments. Past psychology and biology studies showed that some decision-making strategies can ...
Tech Xplore / Contact between 2D and 3D perovskites reshapes crystal order, lifting efficiency to 26.25%
Perovskites, a class of material with a characteristic crystal structure that can convert light into electricity, have proved to be promising for the development of more affordable, flexible, and efficient solar cells than ...
