Osaka Metropolitan University researchers report that melanocytes can persist inside vitiligo lesions after losing their mature, pigment-producing state. Their tissue and cell experiments link the change to remodeling of the basement membrane: laminin-332 and integrin signaling activate c-Jun and push cells toward dedifferentiation. Blocking that pathway restored pigment-related features in laboratory work. The finding suggests a route for future therapies, but it is not a clinical treatment and does not show that every lesion retains recoverable cells.

A Gulf of California group used a coordinated hold-and-ram maneuver that researchers had not previously described.
Researchers documented Gulf of California orcas processing a sharp-tail sunfish with a coordinated sequence: one animal held the fish and released it immediately before another struck at speed. The impact broke the prey apart, allowing the group to feed. The Frontiers in Ethology report describes a previously undocumented behavior from recorded observations. The researchers discuss parental investment and play as possible explanations, but the footage cannot establish the animals' motive.
Marine scientists warn that prolonged anchoring can load hulls with organisms that disperse when shipping resumes.
An international team of 24 marine scientists warns that thousands of commercial vessels stranded for months after the Strait of Hormuz closure could accumulate dense hull-fouling communities. When traffic resumes, ships may transport those organisms to distant ports, creating an unusual invasive-species pulse. The analysis identifies a plausible biosecurity risk, not evidence that a global invasion has already occurred.

FlatMux combines patterned illumination and computational reconstruction to record electrical activity across multiple brain layers.
Rockefeller University researchers introduced FlatMux, an imaging platform that captures voltage activity from roughly 200 neurons at once across several layers of the mammalian brain. The system uses multiplexed light patterns and computational reconstruction to separate fast signals that conventional microscopes struggle to follow. It is a research instrument demonstrated in laboratory settings, not a clinical brain scan.
Sickle cell disease pushed patient stem cells toward senescence, while two approved senolytics restored blood formation in models.
St. Jude researchers found aging-associated features in blood stem cells from patients ages 6 to 23 with sickle cell disease. In mouse models carrying patient cells, senolytic treatment reduced senescence markers and improved blood formation; dasatinib plus quercetin produced similar model results. The work may inform stem-cell collection for gene therapy, but it is preclinical and does not establish a treatment regimen for patients.
Rapamycin temporarily reversed several adult brain and behavior changes linked to maternal inflammation in a mouse model.
A UCLA-led mouse study linked maternal immune activation during pregnancy to lasting network overactivity, sensory sensitivity, repetitive behavior, and seizure vulnerability in adult offspring. One rapamycin dose rapidly improved several measured changes, but the benefit was temporary and repeated dosing lost efficacy. The model identifies a signaling pathway for research; it is not evidence that rapamycin treats autism in people.
SuperAgers and cognitively average peers could not be separated by APOE or current polygenic risk scores.
Researchers compared 142 SuperAgers with 89 cognitively average older adults across five North American sites. APOE status, three Alzheimer's polygenic risk scores, and rare protective variants did not explain exceptional late-life memory. The result narrows one hypothesis and redirects attention toward biological, behavioral, and social protective pathways; it does not identify what preserves memory.
RNA regulation let Streptococcus pneumoniae enter a temporary antibiotic-tolerant state inside a host model.
St. Jude researchers tracked Streptococcus pneumoniae under antibiotic and immune pressure and found adaptations in RNA regulation that supported persistence without classic resistance mutations. The temporary tolerant state can leave a surviving population after treatment. The Cell Host & Microbe result offers targets for future strategies, but it does not change current prescribing or show that every persistent infection uses this mechanism.

CLEAR grounds image embeddings in clinical concepts so researchers can inspect performance instead of accepting a black-box score.
Penn Medicine researchers introduced Concept-Level Embeddings for Auditable Radiology, or CLEAR, a foundation-model approach that ties image representations to clinical concepts. The design is intended to expose what a model recognizes and help investigate failures or performance drift. The publication describes a research framework and benchmarks, not an autonomous diagnostic system or approval for clinical use.
A 60-person Phase II study paired ultrasound with FOLFIRINOX and compared outcomes with a matched historical cohort.
A Seoul National University Hospital Phase II trial enrolled 60 people with borderline-resectable or locally advanced pancreatic cancer; 56 completed focused ultrasound plus FOLFIRINOX. Compared with 56 propensity-matched historical controls, the combination group had higher tumor response, longer median survival, and more curative-intent surgeries. The nonrandomized comparison is encouraging but cannot establish the benefit as firmly as a randomized trial.
The first high-resolution NBCn2 structure guided compounds that reduced activity in tissue studies.
Mount Sinai researchers resolved the high-resolution structure of NBCn2, a brain protein that regulates acid-base balance and has genetic links to epilepsy and other neurological conditions. The team also developed compounds that inhibited the transporter and reduced brain activity in tissue experiments. The work establishes a molecular tool and potential target, not a tested therapy.
Fruit flies stored a directional memory that guided their weaving search after an odor plume vanished.
Rockefeller University researchers tracked fruit flies moving along the fluctuating edge of an odor plume. When scent disappeared, the insects used a short-lived directional memory to cast back toward where the plume was expected, rather than simply moving forward. Neural recordings and behavioral experiments connect the strategy to specific circuitry. The study explains one laboratory navigation behavior, not all animal odor tracking.

Georgia Tech researchers examined when expanding facilities translate into jobs, revenue, infrastructure, and burdens for nearby communities.
Georgia Tech researchers analyzed the local economic promises and public costs surrounding U.S. data-center growth. Their work emphasizes that large capital investment and tax incentives do not automatically produce broad employment gains, while electricity, water, land, and infrastructure demands can be concentrated locally. The findings offer a framework for public decisions; outcomes vary by project, tax agreement, grid, and community.
A national survey found a rise from 9.0% to 13.4% over five years while planning and attempt measures stayed comparatively stable.
A Yale and National Center for PTSD team analyzed a nationally representative 2025–2026 survey of 2,636 U.S. veterans. Recent suicidal thoughts were reported by 13.4%, compared with 9.0% in 2019–2020; lifetime planning and attempt rates changed less. The observational surveys cannot assign a single cause, but they identify younger and female veterans and several clinical factors as priorities for prevention.
A study of more than 1.2 million gallbladder operations associated ICG imaging with fewer serious injuries.
UC San Diego researchers participated in a national analysis of more than 1.2 million laparoscopic gallbladder removals. Operations using indocyanine green fluorescent imaging were associated with fewer bile-duct injuries and other safety improvements. The large observational dataset supports wider evaluation of the technique, but association alone does not prove that imaging caused every difference.
Antibody profiles in nearly 2,000 stored blood samples distinguished people who later developed inflammatory bowel disease.
Mount Sinai researchers examined nearly 2,000 blood samples collected over about a decade from people who later developed Crohn's disease or ulcerative colitis. Antibody signatures appeared years before clinical diagnosis, offering a view of IBD's preclinical phase. The retrospective profiling does not create a screening test and cannot determine whether an individual with a marker will develop disease.
