An analysis of Organ Procurement and Transplantation Network data found that donation after circulatory death climbed from 2% of U.S. donors in 2000 to 49% in 2025, now constituting the majority of donors at 44% of organ procurement organizations, with today's donors being older and medically more complex than in earlier years.
Read the releaseMcGill University and Universidad Adolfo Ibanez researchers synthesized over 100 brain-imaging studies to map how nature exposure shifts neural activity - finding a four-stage cascade from easier sensory processing to reduced stress, restored attention, and quieter mental rumination, even from exposures as brief as three minutes.
Read the releaseA multi-center real-world study of more than 1,700 patients with metastatic castration-resistant prostate cancer found that serial circulating tumor DNA testing consistently detected androgen receptor alterations emerging after treatment - alterations linked to shorter survival regardless of which therapy patients received.
Read the releaseFlorida Atlantic University's Harbor Branch Oceanographic Institute received a $900,000 four-year grant from the National Academies' Gulf Research Program to develop scenario-based sea-level projections for the Gulf of Mexico, integrating climate models, vertical land motion data, and AI-based forecasting tools for underserved coastal communities.
Read the releaseA systematic review of 36 studies spanning 1971 to 2025 found that terminal ileum intubation during colonoscopy should be standard practice with photo documentation, while biopsy is most valuable in patients with diarrhea, suspected IBD, abdominal pain, or anemia - where diagnostic yield reaches 12-27%.
Read the releaseUsing nuclear magnetic resonance and cellular experiments, researchers at Washington State University, University of Arizona, and Mount Sinai identified a specific binding region of the protein leiomodin that acts as a 'leaky cap' controlling actin filament length in heart muscle - a mechanism relevant to inherited cardiomyopathies.
Read the releaseAn analysis of 34 colorectal cancer patients with POLE mutations identified two distinct subgroups: one driven primarily by POLE mutations with an ultramutant phenotype and better outcomes, and one with traditional driver mutations where POLE changes appear secondary. The distinction may guide immunotherapy eligibility.
Read the releaseWhen a Swiss high school shifted from a fixed 7:20 AM start to a flexible model allowing students to begin at 7:30 or 8:30 AM, 95% chose the later option. Students gained 45 minutes of sleep per night, reported fewer sleep problems, and showed measurable improvements in language and math assessments.
Read the releaseA Princeton University study examining 38 countries on five continents found that nations underestimate wastewater greenhouse gas emissions by 19 to 27 percent, primarily due to outdated IPCC 2006 accounting guidelines and excluded systems like latrines and untreated sewage.
Read the releaseA phase 3 randomized trial published in The Lancet shows that orforglipron, a GLP-1 pill with no food restrictions, reduced blood sugar and body weight more than oral semaglutide in people with type 2 diabetes - though gastrointestinal side effects caused 9-10% of patients to stop treatment.
Read the releaseA study of 618 adolescents aged 12 to 17 in Spain found bidirectional links between cardiorespiratory fitness, lower-body strength, speed-agility, and general self-efficacy - suggesting youth health programs should address both physical and psychological dimensions together.
Read the releaseA new set of Mandarin-language cognitive tests, validated in 208 older adults across New Jersey, New York, and the Bay Area, shows strong stability over six months and links to Alzheimer's blood biomarkers - potentially expanding clinical trial access for Chinese Americans.
Read the releaseSociologist Carolina Valdivia's book 'Sanctuary Making' documents how immigration enforcement has penetrated deep into American domestic life - transforming neighborhoods, workplaces, hospitals, and homes into what she calls 'hot spots' - and chronicles how affected families constructed their own protective geographies in response.
Read the releaseResearchers at the University of Basel achieved surgical laser cuts in bone reaching 4.5 centimeters depth by changing the energy distribution profile of the laser beam - more than doubling the previous depth record of 2-3 cm and potentially enabling laser-based cutting for deep joint implant procedures.
Read the releaseAn analysis of U.S. hospital data from 2011 to 2022 found that in-hospital death rates after a first severe heart attack rose by 1.2 percentage points among adults under 55, with women dying at higher rates than men - and with nontraditional risk factors like low income and kidney disease accounting for more of the risk than traditional factors like high blood pressure.
Read the releaseIn the most accurate measurement of iron inputs from an Antarctic glacier to date, Rutgers University marine scientists found that meltwater from an ice shelf delivers far less bioavailable iron to surrounding Southern Ocean waters than widely assumed - raising questions about whether glacial iron fertilization provides a meaningful natural buffer against rising CO2.
Read the releaseA small USC clinical trial used focused ultrasound to temporarily open the blood-brain barrier in patients with recurrent high-grade astrocytoma, then administered immune checkpoint inhibitors. Median overall survival was 13.5 months - substantially longer than the 4-5 months typical for this patient group, though the trial's small size requires larger studies to confirm.
Read the releaseA University of Osaka mouse model of achondroplasia traced how cells carrying the FGFR3 mutation accumulate abnormally in the growth plate's resting zone and fail to progress normally, identifying the CREB signaling pathway as a target with potential for therapeutic intervention in the most common genetic cause of dwarfism.
Read the releaseVirginia Tech researchers discovered that water puddles up to 1 centimeter in diameter can jump off water-repellent surfaces when a bubble trapped inside them bursts - a phenomenon never previously documented and roughly three times larger than the previous size limit for jumping droplets.
Read the releaseAn international team identified Aurora-related kinase 1 (ARK1) as essential for malaria parasite replication by acting as a traffic controller during the parasite's atypical cell division. Switching off ARK1 in lab experiments blocked both replication and mosquito transmission, identifying it as a potential drug target.
Read the releaseAnalysis of daily assault reports and air quality data in Seattle from 2013 to 2023 found that wildfire smoke events, which raised PM2.5 levels by an average of 7 micrograms per cubic meter, were associated with a 3.6% increase in violent assaults on smoke-affected days - the first causal evidence linking wildfire pollution to urban violence.
Read the releaseUniversity of Bath researchers developed a carbon nitride photocatalyst combined with a microporous polymer that uses sunlight to break down PFAS chemicals - offering a proof-of-concept approach that is easy to synthesize and avoids rare materials, with potential future applications in environmental remediation.
Read the releaseThe EU-funded SUPREME project, led by the University of Southern Denmark with TU Graz and international partners, is developing PFAS-free, iridium-reduced PEM electrolysis technology for green hydrogen production - targeting cost and sustainability barriers that currently prevent the technology from scaling.
Read the releaseDenmark has launched the Civil Engineering and the Green Transition in the Built Environment (CEBE) research program with a billion-DKK grant to develop new materials, methods, and knowledge aimed at reducing the construction sector's climate footprint - targeting an industry currently responsible for 37% of global CO2 emissions.
Read the releaseUniversity of Michigan researchers surveyed over 1,000 households in Malawi over two years and found that while solar technology is spreading rapidly in Africa, high costs, low power capacity, and social barriers prevent many families from getting meaningful energy services - even when systems are physically available.
