Diatomite, a crumbly rock made of fossilized algae shells, was tested as a cheap, natural material for measuring radiation doses. When exposed to gamma rays, it glows predictably when heated and maintains a stable signal for at least 35 days, with a response that scales linearly across the tested dose range. Its atomic composition is close to human bone, making it a promising low-cost alternative for radiation dosimetry.

Plain English
A clinical trial tested opicinumab, a drug designed to help the brain repair myelin damage, as an add-on treatment in 263 people with relapsing multiple sclerosis. The drug did not significantly improve the primary disability measure compared to placebo over 72 weeks, though patients who were older or had more advanced disease showed a numerical trend toward benefit. The results will help shape the design of future trials targeting myelin repair.

Plain English
Two simple, low-cost methods were developed to tag and track individual baby cichlid fish that are too small for standard marking techniques. A tattoo ink injection lasts several weeks, while a thin fishing-line tag lasts months, with both allowing unique color-coded identification. Physiological and behavioral tests confirmed the fish recover well from the procedures, making these methods suitable for developmental and long-term studies.

Plain English
Researchers developed a lab test to detect antibiotic, antifungal, and antiparasitic drug residues simultaneously in plant-based protein foods like beans, peas, and nuts. The method was accurate, precise, and sensitive enough to detect very small amounts of contamination. When applied to 97 legume products from Southeast Asian markets, none showed detectable levels of these drug residues.

Plain English
European death records from 26 countries were analyzed to measure how COVID-19 compared to seasonal flu in terms of excess deaths from 2020 to 2023. Before vaccines and control measures were in place, COVID-19 caused far more deaths than typical flu seasons, especially in people over 65. Later in the pandemic, after vaccines rolled out, excess deaths dropped to levels similar to bad flu seasons.

Plain English
Researchers mapped all the biological pathways controlled by the gene PHACTR1, which has been linked to heart and blood vessel diseases. Using four types of molecular data from human cells, they found PHACTR1 does far more than regulate cell shape — it also controls the cell cycle, iron storage, and how mitochondria produce energy. These discoveries identify new potential targets for treating vascular disease.

Plain English
Military pilots and aircrew suffer high rates of neck, shoulder, and back injuries from the physical stresses of flying. A systematic review and meta-analysis of 20 studies found that non-drug rehabilitation therapies — such as exercise and physical therapy — produce modest but real improvements in strength and pain compared to standard care. These findings support embedding rehabilitation specialists within military units to keep flight crews operational.

Plain English
Scientists built a partnership called the Shorebird Science and Conservation Collective to turn GPS tracking data from migratory shorebirds into real conservation action. In three years, 75 organizations contributed over 7 million location records covering 3,420 individual birds across 36 species, which fed directly into 18 conservation projects. The model shows how a dedicated intermediary can rapidly bridge the gap between research data and on-the-ground wildlife protection.

Plain English
Ancient pig DNA from Neolithic sites in the Netherlands and Britain revealed how wild European boars and domesticated pigs from the Middle East interbred when farming spread into northwest Europe. At a Dutch Neolithic site called Swifterbant, pigs showed very high levels of wild boar ancestry and were likely living alongside humans in a commensal relationship — tolerated but not fully controlled — rather than being kept as true livestock. The findings show that early farming communities in northwest Europe relied heavily on wild boar recruitment rather than managing closed herds of domestic pigs.

Plain English
A new X-ray imaging platform was built and tested at the National Ignition Facility to take ultra-sharp snapshots of extremely dense, hot matter — conditions relevant to nuclear fusion research. By using a toroidal (donut-shaped) crystal instead of a spherical one, the system eliminated a common image-blurring problem, achieving better than 10-micrometer resolution with a 110-picosecond time window. A new multi-plane grid approach was also introduced to validate the system's performance and measure the size of the X-ray source in a single shot.

Plain English
Congenital heart disease kills more children in low- and middle-income countries than anywhere else, largely because specialized surgical care is inaccessible. This review examines existing global training models and proposes a new international program to train local healthcare providers using technology-enabled education and standardized credentialing. The goal is a scalable, locally sustained system for pediatric cardiac care rather than reliance on periodic visiting surgical teams.

Plain English
A DNA capture method was developed using short RNA probes to efficiently recover mitochondrial and Y-chromosome DNA from eight major domesticated animal species out of ancient bone, soil, and even fossilized dung samples. The approach required minimal sequencing and worked on samples up to 43,000 years old, recovering complete mitochondrial genomes at high coverage. This tool dramatically lowers the cost of tracking how livestock populations have changed over time across archaeological sites.

Plain English
A 12-week smoking cessation program tailored for LGBTQ+ people living in Oklahoma — a high-stigma environment — was piloted with 20 participants, combining volunteer community activities with remote behavioral support and nicotine replacement therapy. Retention was 80%, and 45% of all participants reported not smoking at the end of the program. Participants also reported feeling greater belonging and reduced internalized stigma, suggesting that addressing minority stress may enhance smoking cessation efforts.

Plain English
Lithium barium borate glass doped with three different rare earth or transition metals — vanadium, samarium, and dysprosium — was tested as a radiation dosimeter under clinical photon beam exposure. Adding dopants substantially improved the linearity and reproducibility of the glass's light-emission response compared to undoped glass. All three doped formulations showed strong potential for accurate radiation dose measurement in clinical and research settings.

Plain English
Daily CT imaging was used to detect and correct patient positioning errors before each radiotherapy session in 411 cancer patients treated at a single center. Positional errors were small overall, averaging about 1-2 mm, and were most consistent in head and neck patients. The findings confirm that daily imaging-guided correction improves treatment precision across cancer sites.

Plain English
Ancient DNA from medieval cemeteries in eastern Spain was analyzed to trace how the Islamic conquest and subsequent Christian Reconquista changed the genetic makeup of the population. North African ancestry entered the region during the Islamic period and persisted in Christian communities until the 17th century, when the mass expulsion of Moriscos in 1609 abruptly severed a long-standing genetic connection between Iberia and North Africa. The study also uncovered evidence of slave trafficking from North Africa and shows the Reconquista itself had little genetic impact.

Plain English
An online sexual health service in Ireland and Northern Ireland added throat swabs to standard STI testing for young heterosexual adults aged 17-24. Gonorrhea was detected in the throat in 92% of all positive cases, with 63% of infections limited to the throat only — infections that would have been completely missed by standard genital-only testing. The findings strongly suggest that throat testing should be included in gonorrhea screening for young heterosexual people.

Plain English
The FIKK kinase family is a group of 15-21 proteins that the malaria parasite Plasmodium falciparum exports into red blood cells to manipulate them. Despite evolving rapidly and diversifying their functions, all FIKK kinases share a conserved ATP-binding pocket, and researchers identified a single compound that inhibits the entire family. A drug that blocks all FIKKs simultaneously could be harder for the parasite to resist and might reduce the severity of malaria infections.

Plain English
Five types of colored commercial cement were tested as low-cost, widely available materials for measuring radiation exposure after the fact. Blue and yellow cements produced the strongest signals when heated after gamma irradiation, with blue cement showing the most linear and sensitive response across doses up to 8 Gy. These findings make pigmented cements a practical candidate for emergency radiation monitoring in scenarios where specialized dosimeters are unavailable.

Plain English
This paper reviews what is known about the health of pregnant people who are incarcerated and identifies major gaps in research. It provides historical context on the intersection of mass incarceration, structural racism, and reproductive rights in the United States. The authors propose a research agenda to address inequities in maternal and infant outcomes for people who experience incarceration during pregnancy.

Plain English
Blood sugar responses to seven different carbohydrate-rich foods were measured in 55 people using continuous glucose monitors, revealing wide differences between individuals eating the same foods. People who spiked strongly after potatoes tended to be insulin-resistant, while strong responders to grapes were more insulin-sensitive, and rice-spikers were more likely to be Asian. Adding fiber, protein, or fat to a rice meal reduced blood sugar spikes less effectively in insulin-resistant individuals, suggesting personalized dietary advice may be more effective than universal guidelines.

Plain English
Thirteen years of citizen science bird observation data were analyzed to track how the breeding range of the long-billed curlew — a large shorebird — has shifted across North America. The species' range expanded northward by about 198 km overall, while regional analysis showed westward shifts consistent with grassland loss in eastern North America. The results demonstrate the value of combining continental-scale and regional analyses to guide conservation of wide-ranging at-risk species.

Plain English
Researchers used multiple imaging and spectroscopy methods to map exactly how a common solar cell material — methylammonium lead iodide — breaks down when an electric field is applied. They identified a threshold electric field strength above which the material rapidly loses mass, forms an amorphous layer, and stops fluorescing, driven by iodine migration, vacancy formation, and decomposition of the organic component. Understanding these degradation pathways is essential for making perovskite solar cells last longer.

Plain English
Raman spectroscopy — a laser-based technique that identifies molecules by how they scatter light — was tested as a tool to distinguish normal human tissue from tissue containing amyloid deposits, the protein aggregates linked to diseases like Alzheimer's and amyloid cardiomyopathy. The technique reliably identified amyloid-specific molecular signatures in heart, kidney, and thyroid samples. It has potential as a rapid, label-free diagnostic tool for amyloid disease.

Plain English
Monte Carlo computer simulations were used to independently verify radiation dose calculations for cervical cancer brachytherapy, comparing them against a commercial treatment planning system. The planning software consistently predicted higher doses to both the tumor and nearby organs than the more detailed simulations did, with differences of roughly 8% for tumor dose. The results highlight that standard planning software may overestimate doses in complex tissue environments, reinforcing the value of independent verification.

Plain English
The diabetes drug dulaglutide was found to reduce fat buildup in the liver through mechanisms beyond simply causing weight loss. In obese animals, dulaglutide directly reduced fat synthesis, stabilized fat droplets, and dampened inflammation and oxidative stress in liver tissue. These weight-independent effects on the liver suggest GLP-1 drugs may benefit patients with fatty liver disease regardless of how much weight they lose.

Plain English
Biochar, a carbon-rich material made by heating organic matter without oxygen, was tested as a cheap radiation dosimeter by measuring how it glows when heated after gamma ray exposure. The material's glow signal scaled reliably with radiation dose up to 200 Gy and remained stable enough for passive dosimetry use. Structural analysis confirmed that gamma rays create measurable damage in the biochar's crystal lattice, validating its dosimetric potential.

Plain English
Clinical outcomes were analyzed for 406 Rwandan children who had heart surgery for congenital heart defects between 2006 and 2020, most of it performed by visiting surgical teams. Overall survival was 96%, but complications — including residual structural problems and pneumonia — occurred in 35% of patients, with malnutrition and long bypass times linked to worse outcomes. The authors recommend a national cardiac registry to improve follow-up and reduce the 14% rate of lost patient records.

Plain English
Ancient horse DNA from 87 specimens spanning the last 26,000 years was used to reconstruct the full genetic history of horses in the Iberian Peninsula. Wild horses native to Iberia were gradually displaced after domesticated horses from the Eurasian steppes arrived around 1850 BCE, with wild restocking continuing until about 350 BCE. Iberian horse bloodlines then had wide influence across Europe, North Africa, and eventually the Americas.

Plain English
A study mapped exactly how a short protein docking sequence on a yeast signaling protein binds to its partner protein, testing thousands of mutations in living cells. Mutations outside the standard docking region also strongly affected binding, revealing that a broader stretch of the protein contributes to the interaction than previously thought. This expands our understanding of how cells achieve precise protein-protein recognition in signaling networks.

Plain English
Researchers used a new brain imaging technique — functional ultrasound — to measure blood flow changes in mice whose brain insulation (myelin) had been stripped away, mimicking multiple sclerosis. Areas with myelin loss showed larger and longer-lasting blood flow responses to sensory stimulation, matching what is seen in MRI scans of MS patients. The approach provides a non-invasive way to study blood vessel changes in MS, which have been underexplored compared to the nerve damage itself.

Plain English
Sixteen children with Schinzel-Giedion Syndrome, a rare genetic disorder, were assessed for their communication, feeding, and movement abilities using caregiver questionnaires. Most children functioned at the level of a newborn to four-month-old in communication and motor skills, though a few showed relative strengths. The findings highlight the need for early feeding support and communication aids, and for measurement tools sensitive enough to detect small improvements in such severely affected children.

Plain English
A semi-automated computer tool called OrbitJ was built and tested to measure facial features around the eyes more quickly and reliably than manual methods. Compared to manual measurements, OrbitJ was highly accurate and cut measurement time from 13 minutes to 5 minutes per photo, while two fully automated AI tools performed less reliably on several key measurements. The tool has practical value for clinicians assessing patients with conditions affecting facial structure.

Plain English
The effectiveness of flu vaccines during the 2023-24 season was measured among patients admitted to hospitals in Northern Ireland with respiratory illness. Overall, vaccination reduced the odds of confirmed flu infection by about 48%, with the strongest protection seen in children (65%) and weaker but still meaningful protection in adults over 65 (40%). Protection was highest in the first two months after vaccination and declined over time.

Plain English
England's NHS Diabetes Prevention Programme was evaluated to see whether completing it reduced the risk of developing not just type 2 diabetes but also 30 other chronic conditions. Program completers had significantly lower rates of diabetes and related conditions for at least two years, with about half the odds of developing diabetes compared to non-attenders. The results suggest the program's benefits extend well beyond blood sugar control, though some of the effect may reflect selection bias.

Plain English
A low-cost DNA chip was developed to track genetic diversity across six farm animal species — cattle, sheep, goats, horses, pigs, and chickens — using just 10,000 genetic markers per species. The chip was validated across 253 breeds and can cluster breeds by ancestry, confirm parentage, and costs about 15 euros per sample when ordered in bulk. This affordable tool fills a gap for gene bank managers and conservation programs that need cost-effective genetic screening.

Plain English
A large ongoing study of UK healthcare workers tracked COVID-19, flu, and RSV infections over the winter of 2023-24. Nearly 1,900 infections were detected among 5,287 workers, and over one-third took sick leave totaling more than 10,000 days. All three viruses contributed to staff absence, highlighting the ongoing strain respiratory infections place on healthcare staffing.

Plain English
Treatment planning software for prostate radiation therapy typically ignores the dose delivered while the radioactive source is moving between positions inside the body. Detailed computer simulations of three commercial radiation delivery machines showed that this overlooked "transit dose" can account for up to 10% of the total radiation dose to surrounding healthy tissue. Accounting for source movement in treatment planning would improve the accuracy of dose estimates to vulnerable organs.

Plain English
A hospital system in Detroit rolled out a digital cognitive behavioral therapy program for insomnia and tracked its real-world impact on 340 patients compared to matched controls. Patients using the digital program were 64% less likely to fill sleep medication prescriptions and showed sustained reductions in outpatient visits after an initial uptick. The implementation approach worked smoothly within existing clinic workflows and reduced ongoing medication use.

Plain English
A study compared healthcare costs for over 11,000 people who used a digital cognitive behavioral therapy program for insomnia against matched patients receiving standard care. Those using the digital program saved between $1,508 and $2,657 per person per year — a 42% cost reduction — largely by reducing reliance on sleep medications and other services. Scaling up digital CBT for insomnia could substantially lower healthcare spending while improving patient access to effective treatment.

Plain English
People living with Alzheimer's disease and related dementias described what matters most to them in their care and treatment. Maintaining independence, staying socially connected, and having a sense of purpose emerged as their top priorities. Their perspectives call for more person-centered care and emphasize that participating in clinical trials can itself feel meaningful and hopeful.

Plain English
A large real-world study examined whether surviving a severe episode of acute pancreatitis increases the risk of developing diabetes. Comparing over 2,000 severe cases to matched mild cases, people with severe pancreatitis were 64% more likely to develop diabetes afterward, with the risk especially pronounced in men. The findings argue for long-term blood sugar monitoring in patients who have had a severe pancreatitis episode.

Plain English
Researchers calculated the extra radiation dose delivered to cancer patients by the daily CT imaging used to position them for radiotherapy, and assessed whether this added dose meaningfully increased risk of complications or secondary cancers. For most patients, the risk was negligible, but for breast cancer patients under 40, higher-dose imaging protocols raised theoretical secondary cancer risk substantially. The findings support tailoring imaging protocols to patient age and cancer site rather than using a one-size-fits-all approach.

Plain English
Three radiation delivery techniques — standard 3D radiotherapy, IMRT, and VMAT — were compared for treating brain metastases while protecting the hippocampus from radiation damage. Both IMRT and VMAT reduced the dose to the hippocampus by more than half compared to standard treatment, while still covering the tumor adequately. IMRT offers a practical option for clinics that lack VMAT equipment.
