A meta-analysis published in JAMA Pediatrics found screen time has a small but significant within-person correlation with later sleep onset in youth, but daily fluctuations in screen use do not meaningfully reduce total sleep duration or quality.

A pilot randomized clinical trial of low-dose lithium in mild cognitive impairment confirmed feasibility and safety but none of the coprimary outcomes reached the prespecified significance threshold, warranting a larger powered trial.

A randomized trial in atrial fibrillation patients with recent stroke history found that adding catheter ablation to standard anticoagulant therapy did not significantly reduce the primary composite endpoint, partly because the observed event rate was lower than predicted.

A new theory from Cold Spring Harbor Laboratory proposes that the developing brain solves the positional information problem by keeping descendant cells near each other, much like how human populations cluster by ancestry - a mechanism validated in mouse and zebrafish models.

A two-year pilot trial at the University of Pittsburgh found low-dose lithium was safe and associated with slower verbal memory decline in older adults with mild cognitive impairment, particularly those positive for amyloid beta. The results justify a larger, more definitive trial.

A research team used electric forces during the bioprinting process to reorganize fibrin proteins into aligned nanoscale tracks at 3,000 volts, producing muscle tissues with correctly oriented cells - a key step for functional muscle repair.

A Jilin University probe uses laser-printed optical structures and capillary action to pull just 50 nanoliters of fluid into a sensing cavity, measuring electrical conductivity without metal electrodes and without interference from temperature or pH.

Southwest Research Institute's MST 8x8 probe attaches externally to storage tanks, using guided ultrasonic waves to generate 2D corrosion maps without the costly process of emptying, cleaning, and manually inspecting the vessel.

A DOE report from 70 researchers across academia, industry, and national labs identifies seven areas where better plasma diagnostics are needed to reach commercial fusion energy, from radiation-hardened sensors to AI-accelerated design tools.

The ORIGIN initiative will use blood samples from the DoD Serum Repository - collected years before any illness - to identify early molecular markers for over 25 diseases including cancers, autoimmune disorders, and PTSD.

A FAU study following 543 students ages 10-14 found that peer influence splits by type: close friends shape emotional health and academics, while popular classmates set the public standards for appearance and social media.

Gulf of Mexico gag grouper seasons have shrunk from six months to just 14 days in 2025. A USF-FWC statistical model now predicts harvest risk more accurately by accounting for how anglers respond to regulation changes.

A Jeonbuk National University study using the RICE-2010 economic-climate model projects 2.48C warming by 2300 under current national pledges - missing the 2C Paris target and leaving global climate damages at nearly US$19 trillion by 2200, versus US$15 trillion under a 1.5C-aligned pathway.

A NIMS Physical Review B study shows that in Mott and Kondo insulators, applying light, magnetic fields, or chemical doping can generate new electronic states within the energy gap - a property absent in ordinary semiconductors that could enable tunable electronic and optoelectronic devices.

A Spanish study published in Basic Research in Cardiology found that brief controlled interruptions of blood flow to a limb - applied using a standard pressure cuff - protected heart function during anthracycline chemotherapy in tumor-bearing mouse models without reducing the drugs' tumor-killing effectiveness.

A Mayo Clinic controlled study found that a single 25 mg dose of amphetamine-dextroamphetamine salts caused significant blood pressure increases, elevated heart rate, and doubled the heart rate spike on standing - from 19 to 38 beats per minute - in healthy young adults without ADHD diagnoses.

Wake Forest University School of Medicine researchers engineered macrophages to express a chimeric antigen receptor targeting mesothelin, a protein on lung cancer cells in the brain. In mouse models, the cells crossed the blood-brain barrier, attacked tumors, reshaped the immune environment, and extended survival - though human trials have not begun.

A University of Michigan study modeling battery degradation across 300 cities under multiple warming scenarios found that batteries made after 2019 lose an average of just 3% of lifetime in a 2-degree-Celsius warmer world, compared to an 8% loss for batteries made before 2018, published in Nature Climate Change.

A University of Warwick study published in Nature Biomedical Engineering analyzed over 8,000 cancer patient samples and found that AI pathology models frequently reach accurate-looking predictions by learning correlations between biomarkers rather than isolating the specific biological signal - raising concerns about reliability in clinical settings.

A collaboration between The Jackson Laboratory and MIT produced a microneedle patch that harvests antigen-specific T cells and inflammatory proteins from skin without needles or biopsies. The first human trial demonstrated live immune cell collection, enabling new ways to monitor responses to vaccines, infections, and cancer therapies.

University of Copenhagen researchers analyzed dental records and cardiovascular outcomes for 568,000 Danish children and found those with multiple cavities had up to 45% higher rates of adult cardiovascular disease - with severe gingivitis linked to a 41% increase - though the study shows association, not causation.

A preliminary study comparing roughly 11,000 chronic migraine patients on GLP-1 drugs to 11,000 on topiramate found GLP-1 users were about 10% less likely to visit the ER and 14% less likely to be hospitalized over the following year - though this observational data cannot establish causation.

A Danish study of 8,300 people with inflammatory bowel disease found that patients with higher polygenic risk scores for developing IBD also face significantly greater odds of a severe disease course - a first step toward personalized treatment decisions at the time of diagnosis.

Applied Microbiology International's video series features two microbiologists - Professor Nicola Holden and Dr. Gil Domingue - examining the raw milk debate: what pasteurization actually does, why recent papers on asthma and microRNAs are intriguing but not yet actionable, and how social media outpaces the science.

In a peer-reviewed study of 76 adults, University of East Anglia researchers used EEG brain scans to show that reward-processing brain circuits continue responding to food cues at full intensity even after satiation - suggesting overeating may be driven more by automatic neural habits than conscious choice.
