Medical Xpress / How multinucleated cells help the brain reorganize after localized astrocyte loss
The human brain contains various types of cells that collectively support its functions. In addition to neurons, nerve cells that communicate via electrical and chemical signals, it also relies on star-shaped cells known ...
Medical Xpress / Large-scale brain scan study reveals unexpected differences in motor and visual regions linked to depression
Major depressive disorder, commonly referred to as depression, is a debilitating psychiatric disorder estimated to affect roughly 5% of the global population. Depression is characterized by persistent sadness and hopelessness, ...
Phys.org / Lichen-like life 600 million years ago may push back origins of fungal-algal partnerships
Two organisms inhabiting a common environment can sometimes mutually influence each other, either benefiting or, in some cases, damaging one another. This mutually beneficial or ambivalent biological relationship is known ...
Medical Xpress / Sleep replay of learned skills can occur independently of the hippocampus, mouse study finds
Sleep is a crucial physiological process that supports recovery, clears metabolic waste products from the brain, regulates metabolism and supports the functioning of the immune system. Sleep is also known to play a key role ...
Phys.org / Two Arctic charr populations evolved in less than a century, study finds
Evolution, the process through which animals and other living organisms change their inherited traits over time, typically unfolds slowly over thousands or even millions of years. Some species, however, can adapt at a faster ...
Phys.org / Physicists create Bose–Einstein condensate from ultracold polar molecules
Bose–Einstein condensates are states of matter that form when particles called bosons are cooled to temperatures that are only a fraction of a degree above absolute zero (i.e., 0 Kelvin [-460°F]). In these states, particles ...
Tech Xplore / Popular vs. reliable sources—a blind spot in how LLMs assess information
Large language models (LLMs), the artificial intelligence (AI) systems underpinning ChatGPT and similar conversational platforms, are now used by many people worldwide to find and summarize information and generate different ...
Phys.org / Rare-earth ions could enable telecom-ready control of interacting qubits
Quantum technologies are devices and systems that exploit the laws of quantum mechanics and could perform tasks that are difficult or impossible to tackle using their classical counterparts. These technologies process and ...
Medical Xpress / Brain fluid structure may flag future dementia risk years before diagnosis
Dementia, a progressive loss of memory and decline in mental function that can be caused by various neurological conditions, is estimated to affect more than 57 million people worldwide. Identifying specific biological and ...
Phys.org / Moon's thick crust could amplify elusive gravitational-wave signals
Gravitational waves are tiny ripples in the fabric of spacetime that are produced when massive objects in the cosmos accelerate or collide. By detecting these waves, astrophysicists can study various cosmic events, including ...
Phys.org / How flying together helps Andean condors save energy
Animals are constantly moving to find food, water, suitable habitats, mates and safe places to rest. Because moving requires substantial energy, animals often rely on various biological and behavioral strategies to reduce ...
Medical Xpress / Working memory rapidly updates its priorities after distractions, study finds
When humans tackle many everyday tasks, ranging from driving to completing household chores and work assignments, they rely heavily on working memory. This is the brain's ability to temporarily store and manipulate important ...
Phys.org / A quantum heat engine that simultaneously provides work and refrigeration
The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins the operation of numerous ...
Tech Xplore / Seed crystals push solvent‑free perovskite cells to 25.53% efficiency
Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries, where they are helping to reduce reliance on electricity generated from fossil fuels. While most solar cells used today ...
Phys.org / Plumage reflectance framework offers new insight into how birds evolved heat-controlling feathers
Birds can inhabit various environments with different climates and temperatures, ranging from cold polar regions to scorching hot deserts. To survive and thrive in these very different environments, they need to effectively ...
