Washington University researchers report that biomolecular condensates formed from disordered proteins create interfacial electric fields and alter nearby water in ways that accelerate several hydrolysis reactions. The effect appeared with laboratory condensates and in bacterial cells, including reactions involving nucleic acids and ATP. The team calls the emergent catalysts "condenzymes," but the finding does not make every cellular droplet an enzyme or establish a disease treatment.

A prototype ring draws sweat through an osmotic hydrogel and tracks as many as four biochemical markers at once.
A UC San Diego-led team integrated an electrochemical sensor array, passive osmotic sweat collection, fluid channels, electronics, and a flexible battery into a ring. In initial tests with healthy volunteers and people with type 1 diabetes, configurations measured up to four markers selected from glucose, ketones, vitamin C, uric acid, lactate, and alcohol, while the battery supported roughly 12 hours of operation. The prototype tracked trends against commercial references, but it is not an approved medical device and the study does not establish clinical outcomes.
A new USDA-funded project will compare volatile compounds and bacteria to build a species-specific lure for New World screwworm.
Colorado State University researchers are beginning a USDA-funded project to identify the volatile compounds and wound bacteria that attract New World screwworm flies. By comparing those signals with secondary screwworm, the team aims to design a lure specific enough for surveillance traps as detections reach the southern United States. The project is a research plan, not a finished lure or evidence that current monitoring has failed.

A nickel-catalyzed electrochemical method joins alkyl alcohols directly without first converting them into conventional coupling partners.
A Nature Synthesis paper reports a doubly dehydroxylative route that makes carbon-carbon bonds directly between alkyl alcohols under nickel catalysis. The method tolerated varied functional groups and modified hydroxyl-containing bioactive molecules, potentially removing prefunctionalization steps from some syntheses. It is a laboratory synthetic platform, not evidence that a drug can now be manufactured at scale.
A modified Bifidobacterium delivered an altered IL-2 payload to oxygen-poor pancreatic tumors in animal models.
University of Chicago researchers engineered Bifidobacterium longum to accumulate in hypoxic tumors and release a modified interleukin-2 payload. In mouse models of pancreatic cancer, the system activated tumor-fighting CD8 T cells and improved responses when combined with chemotherapy, radiation, or anti-PD-L1 treatment. The work has not been tested in people, and safety and control of a living therapy remain open questions.
Whole-genome analysis linked germline variants to treatment activity and toxicity in aggressive lymphoma trials.
Researchers analyzed whole genomes from more than 200 people treated with CAR-T cells in two aggressive-lymphoma trials. Variants near STXBP2 correlated with toxicity, ADAMTSL3 variants with protection, and PTPN22 variants with CAR-T expansion and activity. These are associations that need replication; they do not yet justify selecting or withholding treatment from an individual patient.
A phase 3 trial found better event-free survival with enfortumab vedotin plus pembrolizumab around bladder-cancer surgery.
In a phase 3 study of 808 people with muscle-invasive bladder cancer at 158 sites, perioperative enfortumab vedotin plus pembrolizumab reduced the risk of progression, recurrence, or death by 47% compared with cisplatin-based chemotherapy. At two years, roughly 80% of patients in the combination group and 66% in the chemotherapy group were event-free. Serious side effects were more frequent with the new regimen, so the survival result does not erase treatment tradeoffs.
Lipoic acid trisulfide limited nitration of hepatocyte growth factor in biochemical tests and a mouse disuse model.
Kyushu University researchers found that lipoic acid trisulfide reduced chemical nitration of hepatocyte growth factor, a modification that weakens its ability to bind the c-Met receptor. At a high ratio in laboratory tests, protected HGF more than doubled receptor binding, and suspended mice showed less nitration after treatment. Aging studies, dosing, and safety work are still needed before the result can support a therapy.

A simplified hadronization model ran on IBM hardware as researchers test routes toward harder particle-physics calculations.
Berkeley Lab and Oak Ridge researchers used IBM quantum hardware to simulate a simplified version of hadronization, the process by which quarks and gluons form composite particles. The Physical Review D study develops methods for representing the evolving quantum system and checking hardware output. It is groundwork for future calculations, not a full simulation of quantum chromodynamics or a replacement for collider experiments.
Higher TMAO levels were associated with atrial fibrillation and electrical changes in a large clinical cohort and cell studies.
Cleveland Clinic researchers studied more than 5,000 people undergoing heart procedures and found that higher trimethylamine N-oxide levels were associated with atrial fibrillation. Laboratory experiments also linked TMAO exposure to changes in the electrical environment of heart cells. The clinical finding is observational and does not show that changing diet or TMAO alone will prevent the rhythm disorder.
Modeling suggests a rare convergence could have pushed the eastern Mediterranean past a severe drought threshold.
Stockholm University researchers used the EC-Earth climate model to test how several natural cycles could have combined over the eastern Mediterranean during the late Bronze Age. When the cycles aligned, the model produced an unusually persistent drought capable of crossing a regional hydroclimatic threshold. The result supports climate as one pressure among many; it does not establish drought as the sole cause of social upheaval.
Tap-water samples and long-running urine data point to persistent, geographically uneven exposure across participating communities.
Columbia University researchers compared drinking-water samples collected from 2022 through 2024 with urinary lithium measurements gathered over 15 years in western U.S. Tribal communities. They found widespread exposure and substantial regional variation, consistent with water as a persistent source. The study maps exposure; it does not by itself establish a health effect or define a safe community-level threshold.

Age-stratified allele frequencies in more than 72,000 people revealed genetic variants that may still be under selection.
Researchers analyzed Taiwan Biobank data from more than 72,000 Han Taiwanese participants, comparing allele frequencies across age groups to identify variants whose representation changes between generations. The American Journal of Human Genetics study found signals consistent with ongoing natural selection, including rare variants connected to disease traits. Cross-sectional age patterns can be influenced by population history and participation, so the framework needs confirmation in other cohorts.
U.S. data from 2014 through 2021 found similar seasonal peaks in mass shootings and suicide deaths.
Researchers comparing national records from 2014 through 2021 found that mass shootings and suicides both peaked during summer months. The parallel seasonal pattern may help frame prevention research and timing, but the analysis does not identify a shared cause or predict individual behavior. Differences in definitions, reporting, and the relatively short study period also limit interpretation.
Lower cerebral glucose metabolism on existing PET scans was associated with higher one-year mortality in advanced disease.
A retrospective study of patients with advanced non-small cell lung cancer examined FDG-PET scans acquired between 2010 and 2023. Lower brain glucose metabolism was associated with higher one-year mortality and added prognostic information beyond established clinical variables. The marker is an association from historical records, not proof that brain metabolism drives survival or that it should yet change treatment.
Operando measurements show copper and titanium sites cooperating dynamically as a photocatalyst turns carbon dioxide into carbon monoxide.
Chinese Academy of Sciences researchers tracked single copper atoms on titanium dioxide while the material photoreduced carbon dioxide to carbon monoxide. In-situ spectroscopy indicated that the copper and neighboring titanium sites change roles under illumination and cooperate during the reaction rather than acting as a fixed center. The mechanistic study explains a laboratory catalyst; it does not establish industrial carbon removal or energy efficiency.
