Bismuth, a puzzling material in quantum research, has now revealed a surprising twist. Kobe University scientists discovered that its surface properties can obscure its true nature, challenging a foundational assumption in topological material science. For nearly two decades, scientists have puzz
The emerging field of neurosymbolic AI could solve these issues, while also reducing the enormous amounts of data required for training LLMs. So what is neurosymbolic AI and how does it work?
LLMs work using a technique called deep learning, where they are given vast amounts of text data and use advanced statistics to infer patterns that determine what the next word or phrase in any given response should be. Each model—along with all the patterns it has learned—is stored in arrays of powerful computers in large data centers known as neural networks.
LLMs can appear to reason using a process called chain-of-thought, where they generate multi-step responses that mimic how humans might logically arrive at a conclusion, based on patterns seen in the training data.
It looks like the “learn to code” push is backfiring spectacularly for those who majored in computer science in college.
People who follow a MIND diet, even if started later in life, were significantly less likely to develop Alzheimer’s disease or related forms of dementia, according to new research.
The MIND diet stands for “Mediterranean-DASH Intervention for Neurodegenerative Delay” and combines many elements of the Mediterranean diet and DASH (“Dietary Approaches to Stop Hypertension”). It emphasizes brain-healthy foods like leafy greens, berries, nuts and olive oil.
The study, being presented Monday at the American Society for Nutrition’s annual meeting, analyzed data from nearly 93,000 U.S. adults aged 45 to 75 starting in the 1990s.

Objective To improve early diagnosis of patients who have basilar artery occlusion (BAO) and to provide evidence for treatment decisions based on clinical characteristics, treatment strategies, and prognostic outcomes of cases of bilateral hearing loss as a prodromal symptom.
Methods We conducted a retrospective analysis of six patients who had BAO with an initial symptom of hearing loss. This analysis encompassed demographic data, clinical symptoms, examination findings, treatment approaches, and prognostic outcomes.
Results Six patients (mean age 62±16.5 years) presented with bilateral sudden hearing loss and were diagnosed with proximal BAO. All had subtle initial symptoms, leading to diagnostic delays (mean 13 ± 5.4 hours). Five underwent endovascular treatment (EVT), and all patients required rescue balloon angioplasty because of underlying atherosclerotic stenosis.
The venous system maintains the health of our brains by removing deoxygenated blood and other waste products, but its complexity and variability have made scientific study difficult. Now, a UC Berkeley-led team of researchers has developed an innovative MRI technique that may expand our understanding of this critical system.
In a study published in Nature Communications, the researchers demonstrate how their new imaging method, Displacement Spectrum (DiSpect) MRI, maps blood flows “in reverse” to reveal the source of blood in the brain’s veins. This approach could help answer long-standing questions about brain physiology as well as provide a safer, more efficient way to diagnose disease.
Like some current MRI methods, DiSpect uses the water in our blood as a tracing agent to map perfusion, or blood flow, in the brain. The water’s hydrogen atoms possess a quantum mechanical property called spin and can be magnetized when exposed to a magnetic field, like an MRI scanner. But what makes DiSpect unique is its ability to track the “memory” of these nuclear spins, allowing it to map blood flow back to its source.
A trial of an interactive game that trains people to alter their brain waves has shown promise as a treatment for nerve pain—offering hope for a new generation of drug-free treatments.
The PainWaive technology, developed by UNSW Sydney researchers, teaches users how to regulate abnormal brain activity linked to chronic nerve pain, offering a potential in-home, noninvasive alternative to opioids.
A recent trial of the technology, led by Professor Sylvia Gustin and Dr. Negin Hesam-Shariati from UNSW Sydney’s NeuroRecovery Research Hub, has delivered promising results, published in the Journal of Pain.
In cohorts of lean controls, obese participants without Type 2 Diabetes Mellitus (T2DM) and obese T2DM participants, we find that T-cell expression of senescence biomarkers is altered only in the T2D…
Are we facing tech-stinction?
An Oklahoma tech expert predicted that artificial intelligence will become so omnipresent on the planet that Earth — with a current estimated population of about 8 billion — will have just 100 million people left by the year 2300.
“It’s going to be devastating for society and world society,” Subhash Kak, who teaches computer science at Oklahoma State University in Stillwater, Oklahoma, told the Sun. “I think people really don’t have a clue.”
