Researchers have created functional brain-like tissue without relying on any animal-derived materials, marking a major step toward more ethical and reproducible neurological research. By transforming a chemically inert polymer (PEG) into a porous, maze-like scaffold, scientists enabled donor brain cells to organize into active neural networks.

A new wearable system uses stretchable electronics and artificial intelligence to interpret human gestures with high accuracy even in chaotic, high-motion environments. Unlike traditional gesture-based wearables that fail under movement noise, this patch-based device filters interference in real time, allowing gestures to reliably control machines such as robotic arms.

A sweeping analysis of 235 studies shows that holding onto impossible goals harms mental and physical wellbeing, increasing stress and lowering life satisfaction. In contrast, releasing unachievable goals — and crucially, shifting toward new, attainable ones — improves mood, resilience, and overall psychological health.

A rare intracranial brain-recording study revealed that tirzepatide, a GLP-1 and GIP receptor agonist, temporarily silences craving-related neural activity in a key reward circuit of the brain. Using implanted electrodes in a patient with treatment-resistant obesity and loss of control eating, researchers observed that the drug initially shut down signaling in the nucleus accumbens.

New research shows that the brain separates “what an odor is” from “how it feels,” with each processed at distinct times. Shortly after an odor is presented, the brain activates a fast, objective signal that tracks molecular features and supports accurate odor discrimination.

New research shows that depression beginning before age 25 has a much stronger hereditary component than depression that emerges later in life. By analyzing genetic data from over 150,000 people with depression, researchers identified distinct genetic regions linked specifically to early-onset cases.

New research shows that people often feel worse when telling others about their good deeds than when keeping them private or discussing personal achievements. Across five studies, participants predicted more shame and embarrassment when sharing altruistic acts, partly because they feared appearing motivated by social credit.

Experts reviewing decades of research conclude there is no scientific evidence that the gut microbiome causes autism. They highlight major flaws in observational studies, mouse experiments, and clinical trials, including inadequate sample sizes and contradictory findings.

New research reveals that women with long COVID show distinct biological disruptions — including gut inflammation, anemia, and abnormal hormone levels — that may explain their heightened and persistent symptoms. These findings emerged from immune, biomarker, and genetic analyses in people one year after infection.

Researchers surveyed more than 4,300 people to create the first large-scale inventory of modern real-life risky choices, revealing which decisions people actually struggle with in daily life. The most common risks weren’t financial or recreational—they were job-related choices, such as quitting or starting a new role, followed by health, financial, and social decisions.
