Can you recognize an old friend, but forget what you had for breakfast yesterday? Our brains constantly rearrange their circuitry to retain information, but the molecular basis behind this process isn't well understood. New research suggests that complex sugars called glycosaminoglycans might play a major role in the 'plasticity' of the brains of mice and could be used to repair neural connections after injury.

Research is underway around the world to find alternatives to our current electronic computing technology, as great, electron-based systems have limitations. A new way of transmitting information is emerging from the field of magnonics: instead of electron exchange, the waves generated in magnetic media could be used for transmission, but magnonics-based computing has been (too) slow to date. Scientists have now discovered a significant new method: When the intensity is increased, the spin waves become shorter and faster -- another step towards magnon computing.

A new method allows large quantities of muscle stem cells to be safely obtained in cell culture. This provides a potential for treating patients with muscle diseases -- and for those who would like to eat meat, but don't want to kill animals.

The Noelin family of secreted proteins bind to the external portion of AMPA glutamate receptors and stabilize them on the neuronal cellular membrane, a process necessary for transmission of full-strength signals between neurons, according to a new study.

Scientists have made a significant advance in developing alternative materials for the high-speed memory chips that let computers access information quickly and that bypass the limitations of existing materials. They have discovered a way that allows them to make sense of previously hard-to-read data stored in these alternative materials, known as antiferromagnets.

From text-generating ChatGPT to voice-activated Siri, artificial intelligence-powered tools are designed to aid our everyday life -- as long as you speak a language they support. These technologies are out of reach for billions of people who don't use English, French, Spanish or other mainstream languages, but researchers in Africa are looking to change that. Scientists now draw a roadmap to develop better AI-driven tools for African languages.

While engaging in cell division research, researchers made a surprisingly quiet discovery. When cells express RNA, there is always some fluctuation, or noise, in how much RNA is produced. The scientists found several genes whose noise dips below a previously established threshold, known as the noise floor, during expression.

Researchers hope that a new, publicly available database they have created will shrink, not grow, over time. That's because it is a compendium of the thousands of understudied proteins encoded by genes in the human genome, whose existence is known but whose functions are mostly not.

New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.

Tumor cells are known to be fickle sleeper agents, often lying dormant in distant tissues for years before reactivating and forming metastasis. Numerous factors have been studied to understand why the activation occurs, from cells and molecules to other components in the so-called tissue microenvironment.

Researchers have unveiled an artificial intelligence-based model for computational imaging and microscopy without training with experimental objects or real data. The team introduced a self-supervised AI model nicknamed GedankenNet that learns from physics laws and thought experiments. Informed only by the laws of physics that universally govern the propagation of electromagnetic waves in space, the researchers taught their AI model to reconstruct microscopic images using only random artificial holograms -- synthesized solely from 'imagination' without relying on any real-world experiments, actual sample resemblances or real data.

The success of artificial intelligence technologies depends largely on how physicians interpret and act upon a tool's risk predictions -- and that requires a unique set of skills that many are currently lacking, according to a new perspective article.

The research team at The University of Texas at Austin created a noninvasive electroencephalogram (EEG) sensor that they installed in a Meta VR headset that can be worn comfortably for long periods. The EEG measures the brain's electrical activity during the immersive VR interactions.
