Hamstring Hurdles Prompt MRIs for Williams and Harper After Game 2

Hamstring Hurdles Prompt MRIs for Williams and Harper After Game 2

Thunder forward Jalen Williams and Spurs guard Dylan Harper exited Game 2 with hamstring injuries and will undergo MRIs to determine if there’s a re-injury. Williams’ left hamstring tightness, a strain he suffered earlier in the playoffs, could sideline him longer, while Harper’s right hamstring is also being evaluated. If Williams is out, Ajay Mitchell or Cason Wallace could see increased minutes for OKC; if Fox and Harper miss time, the Spurs may rely on Stephon Castle and Jordan McLaughlin, though Castle has struggled with turnovers. Davis coach updates are pending medical results.

ADHD Is Not One Thing: Brain Scans Reveal Three Distinct Profiles

A multinational MRI study of about 1,800 children reveals ADHD can be divided into three brain-based biotypes with distinct neural fingerprints, including a hidden severe type marked by widespread changes in emotion-regulation regions and neurochemical signatures. The findings suggest ADHD treatment may need to target emotion regulation and biology beyond dopamine-focused stimulants; however, MRI cannot diagnose individuals yet. Over four years, most groups improved in attention, but the severe biotype often maintained emotional difficulties and higher risk for mood disorders. The study was replicated in a separate cohort, bolstering the case for biological subtypes guiding future diagnosis and personalized care.

NG101 Antibody Clears Growth Barrier to Boost Spinal Cord Repair

In a multicenter phase 2b trial, NG101 neutralizes Nogo-A, enabling surviving and newly grown nerve fibers to regenerate around spinal lesions and reestablish connections with the spinal centers that control the limbs. MRI data show faster lesion reduction and preserved tissue, providing objective biomarkers for early treatment effects and suggesting potential gains in hand/arm function after acute cervical spinal cord injury, though full mobility restoration remains uncertain.

Metamaterial MRI Antenna Delivers Sharper Eye and Brain Imaging on Existing Scanners

Researchers at the Max Delbrück Center and Rostock University Medical Center unveiled a metamaterial-based MRI antenna that strengthens signals from deep tissues, enabling higher-resolution images of the eye and occipital brain regions and potentially shorter scan times without new equipment. Tested at 7.0 Tesla on volunteers, the compact antenna can be adapted to different body parts, may help reduce heating near implants, and could enhance MRI-guided therapies; larger clinical studies are planned and the approach targets broader organ imaging in the future.

Pregnant Brains Rewire Across Gestation, Redefining Maternal Neuroscience

Pregnant Brains Rewire Across Gestation, Redefining Maternal Neuroscience

A US-led Maternal Brain Project tracked brain changes in several mothers from before through after pregnancy using MRI, finding widespread cortical gray-matter loss during gestation with partial rebound after birth and notable shifts in cerebrovascular dynamics. Across 400 brain regions, about 97% showed alterations, suggesting the maternal brain adapts to motherhood rather than deteriorating. The work, involving about 20 participants over 18 months and more than 150 scans, aims to build an open-access database to answer questions about cognition, postpartum mood, and pregnancy complications, and to address historic underrepresentation of women in neuroimaging research.

Moderate Drinking May Reduce Brain Blood Flow, Especially With Age

A small study of 45 healthy adults found that even moderate alcohol use is linked to reduced brain blood flow, with stronger effects in older participants and in frontal/temporal regions tied to thinking and language. The findings suggest potential cognitive implications but come from a limited, observational sample, so researchers call for larger studies before any guideline changes.

Yawning May Help Clear the Brain, MRI Study Finds

A UNSW-led study used MRI to watch 22 healthy participants yawning, deep-breathing, and resting. Yawns moved cerebrospinal fluid away from the brain (unlike deep breaths), while both yawns and deep breaths increased blood flow leaving the brain. The findings suggest yawning could play a role in brain cleaning or cooling, and that yawning patterns are highly individual, likely governed by a central pattern generator; the study was published in Respiratory Physiology & Neurobiology (2026).

Ultra-processed diets linked to fatty thigh muscles and knee joint risk

Ultra-processed diets linked to fatty thigh muscles and knee joint risk

A UCSF-led study of 615 people at risk for knee osteoarthritis found that higher ultraprocessed food intake, irrespective of total calories, is associated with greater intramuscular fat in the thigh, a sign of weaker muscles that may raise knee joint stress; while causality isn’t proven, experts advise low-impact exercise and a diet of real, minimally processed foods, plus practical steps to cut ultraprocessed items (read labels, add whole foods, swap sugar-sweetened drinks, and eat out less).
