A Baycrest-led study found that experienced birders have denser, more organized brain tissue in attention and visual-perception regions, and those same regions show stronger activation when they view unfamiliar bird species, suggesting that expertise reshapes brain structure to support efficient, template-free recognition across the lifespan.
Australian researchers report preliminary MRI-based evidence that ME/CFS patients have reduced glymphatic (brain-waste clearance) function, detected with a non-invasive diffusion MRI approach and most evident in the brain's right hemisphere; the findings, published in Frontiers in Neuroscience, link sleep problems and cognitive symptoms to impaired brain clearance and suggest a potential non-invasive path toward diagnosis and treatment—though the study is small and further research is needed.
A study of 2,044 older adults (median age 69) found that higher blood vitamin C levels are associated with healthier brain structure—higher grey matter volume—and stronger connectivity in the brain's default mode network on MRI, even after adjusting for age and health factors. The study is observational (cross-sectional), so it shows association, not causation, and researchers caution that vitamin C is not a dementia cure. The article notes vitamin C’s antioxidant role and involvement in neurotransmitter production, and suggests obtaining vitamin C through a balanced diet (e.g., citrus, amla, guava, kiwifruit, peppers, leafy greens) rather than unsupervised supplementation.
Arizona Diamondbacks pitchers Michael Soroka and outfielder Jordan Lawlar were placed on the injured list after Friday’s win over the Twins, with Soroka diagnosed with a strained left glute and Lawlar with a strained right hamstring; both will undergo MRIs to determine the extent of the damage. Left-hander Philip Abner and utilityman Tim Tawa were recalled from Triple-A. Soroka exited after one inning; Lawlar left in the eighth while sprinting to first on a bunt. The injuries add to Arizona’s rotation and depth concerns, as Ryne Nelson is already on the IL and the club eyes replacements such as Mitch Bratt or Jose Cabrera.
Royals shortstop Bobby Witt Jr. left Thursday’s game with right knee discomfort and underwent additional testing; an MRI confirmed a Grade 1 MCL sprain. He’ll miss Friday and Saturday at minimum and be re-evaluated Sunday, with the Royals hopeful he can avoid an injured-list move.
In a Japanese study of about 2,000 older adults, higher blood plasma vitamin C levels were linked to better-preserved brain gray matter and stronger connectivity in the default mode network, even after adjusting for age, smoking, diabetes and other factors. While the finding suggests vitamin C status may play a role in brain health, the study is observational and cannot prove causation, with limitations including a single blood measurement and limited generalizability beyond older Japanese adults. The results highlight dietary vitamin C sources rather than supplements as a potential piece of the broader brain-health puzzle.
A Japanese observational study of 2,044 older adults found higher blood levels of vitamin C were linked to healthier brain structure—larger gray matter volume and stronger connectivity in the brain’s default mode network—independently of age, smoking, diabetes, and other factors. The study used plasma measurements rather than dietary estimates and cannot prove causation. Researchers caution results may not generalize beyond mostly older Japanese participants and note limitations like a single blood measurement; they suggest maintaining vitamin C through diet (citrus, berries, tomatoes, leafy greens) as a potential way to support brain health, while calling for more research.
Braves right-hander Spencer Strider is expected to avoid elbow surgery after an MRI showed no ligament damage, with the issue diagnosed as elbow inflammation that sidelined him to the injured list. He’ll meet with Dr. Keith Meister to map a recovery timeline; Strider previously had Tommy John surgery in 2019 and a 2024 UCL internal-brace procedure. In his absence, JR Ritchie will get another rotation opportunity as Strider recovers, following an eight-start stretch that included a 5.31 ERA over 39 innings with a 27.9% strikeout rate and 12.1% walk rate.
A study of about 2,000 adults over 64 found that lower blood plasma vitamin C is associated with reduced gray matter volume and weaker connectivity in the brain's default mode network, suggesting vitamin C status may relate to brain aging, though the results are observational and longitudinal research is planned to explore causality and cognitive impacts.
A new wave of prostate cancer care combines MRI, robotics, and AI to diagnose more accurately via transperineal biopsies guided by the Mona Lisa system, reducing infections and enabling focal, personalized treatments.
A UK Biobank study of about 23,000 middle-aged and older adults followed for roughly nine years found that sleeping outside the seven-to-nine-hour window (especially fewer than seven hours), frequent daytime napping, and sleeplessness each correlate with higher brain white matter lesion volumes on MRI, a marker linked to aging and dementia risk. After adjusting for vascular and lifestyle factors, snoring and unintentional daytime dozing did not show the same links. Short sleep showed a stronger association than long sleep, and while naps can aid alertness, frequent napping may signal underlying sleep problems. The researchers emphasize sleep as a modifiable risk factor that could help reduce brain aging and dementia risk, though nap duration details were not captured in this study.
Elly De La Cruz exited Cincinnati's win over Atlanta with right hamstring tightness and will undergo an MRI to determine the injury's extent; if no serious damage is found but soreness persists, the Reds could use a short bench during the Royals series, with potential infield depth calls if he’s sidelined.
Red Sox pitcher Garrett Crochet is dealing with tightness in his left lat, will undergo an MRI early this week, and will not participate in his scheduled throwing session, leaving his return date uncertain.
Researchers used physics-informed AI to infer three-dimensional brain fluid velocities from dynamic MRI, revealing two distinct glymphatic flows: a fast surface passage and a slow deep-tissue flow roughly 50 times slower. The method, demonstrated in animal models, aims to enable whole-brain fluid mapping for comparing healthy and diseased brains, with potential clinical uses in assessing brain circulation after concussion and screening for Alzheimer’s-related risks.
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.
