Researchers developed a digital twin that automatically uses real-time data to adjust how products are disassembled. In a representative scenario, it reduced modeled lead time by 78% and increased profit by 2% compared with a process without real-time replanning.
Researchers analyzed Japanese health-insurance claims for people aged 75 or younger who had tooth extractions between April 2012 and March 2024. After dental antibiotic guidelines were introduced or updated, use of third-generation cephalosporins fell overall, especially in some hospitals and later in dental clinics; surgical-site infection rates did not change in the analysis. Because this was an observational study, the findings show patterns associated with the guidelines rather than proving that the guidelines alone caused them.
A study of Boston Logan International Airport found that aircraft-related ultrafine particle pollution differed between winter and summer. Including aircraft-specific particle sizes in the analysis improved agreement between computer estimates and measurements from seven monitoring stations.
Researchers developed an iron-based cathode for protonic ceramic fuel cells that reached a peak power density of 2.2 W/cm² at 700 °C. The cell also operated stably for more than 400 hours, according to the study.
Researchers developed a 3D-printed gripper that changes shape at 40.5 °C, close to physiological temperatures. In laboratory tests, it recovered about 94% of its programmed shape and retained about 98% of that recovery after 15 cycles.
Researchers reviewed 110 randomized clinical trials involving 22,608 children and adults who received cefepime or another beta-lactam antibiotic. Across all included trials, cefepime was associated with slightly higher odds of death, although the overall statistical interval included the possibility of no difference.
UFC winners have increasingly been associated with striking actions, especially significant strikes, over the sport’s modern history. Grappling has become less prominent in separating winners from losers, but the findings point to a combined striking-and-grappling skill set rather than a simple shift away from grappling.
Researchers reviewed 77 studies published from 1990 through 2023 to estimate how often neurocysticercosis—a brain infection caused by the larval stage of a tapeworm—occurred among people with epileptic seizures. Across studies with clear definitions and appropriate testing, the estimated proportion was 25.2%, but the studies differed substantially and the result should not be treated as universal.
Researchers tested two ultra-light foams used in elite racing shoes and found that both returned energy with little loss while behaving differently under stretching and sideways forces. An artificial-intelligence-based modeling approach captured these behaviors and could support simulations of running economy and individual injury risk.
Researchers have described Stolephorus lotus, a previously unknown anchovy species from Australia’s Northern Territory. Its identification is based on several physical features that distinguish it from two related species.
Researchers conducted a systematic review of published human studies on paradoxical vocal fold motion linked to confirmed disorders of the brain, spinal cord, nerves, or related systems. Across 11 included studies, 42 patients were identified with both this vocal-fold movement problem and a confirmed neurological disorder. The findings describe reported associations and treatment outcomes; they do not establish how common these causes are or prove that one condition caused another.
An AI-based security system deployed on a core banking platform identified 1,100 incidents during a year of operation, according to a study in Scientific Reports. The bank reported a drop in false alarms from 32% to 2% and in average response time from 45 minutes to five.
A multi-processor ultraviolet reactor reduced Ralstonia solanacearum and Pectobacterium carotovorum in surface irrigation water by 4 logs, or 99.99%, after pre-filtration. In tests with tomato seedlings and potato tubers, treated water significantly suppressed bacterial wilt and soft rot.
This retrospective human cohort study examined 60,980 adults with autoimmune rheumatic conditions who developed COVID-19 between December 2020 and August 2024. Researchers found that vaccinated patients, including those who received an updated 2023–2024 vaccine or a booster, had lower adjusted odds of COVID-19-related hospitalization than patients with no recorded vaccine doses. The study found associations, not proof that vaccination caused the lower risk.
The Devil’s Arrows, Britain’s tallest surviving standing stone alignment, were probably deliberately quarried at Brimham Rocks and transported about 18 kilometres, a study finds. The conclusion is based on matching geological age patterns, regional ice-flow evidence and similarities in surface weathering.
