A study of nearly 500,000 births in Ontario found that Asian parents experience 1.5 times the obstetric trauma rate of White parents, while Black economic immigrant and refugee parents face 20-30% higher risk. Duration of residence in Canada was associated with declining risk, suggesting better care access over time.

The American College of Sports Medicine published its first resistance training update since 2009, based on 137 systematic reviews and over 30,000 participants. The central message: any resistance training improves strength, muscle size, and function. Elastic bands, bodyweight, or barbells - consistency beats complexity.

The largest global study of emergency patients presenting with visible blood in urine found that 10% die within 90 days and 25% have underlying cancer. Patients who received a CT scan or cystoscopy within 48 hours were diagnosed faster and had better outcomes. The WASHOUT study spanned 8,500 patients across 380 hospitals.

New research comparing prostate cancer screening with Germany's established breast cancer program finds similar rates of significant cancer detection and biopsy accuracy, with prostate biopsies actually more likely to find significant cancer (50-68% vs 10%). The findings, presented at EAU26, challenge the rationale for rejecting organized prostate screening.

Insilica's ToxIndex platform uses AI agents to produce comprehensive toxicological risk assessments in hours instead of months. Endorsed by Johns Hopkins CAAT director Thomas Hartung, the platform integrates 600+ open-source models, in vitro evidence from 60 billion data triples, and regulatory databases to deliver fully traceable safety evaluations.

The RESIL-Card consortium has launched a free online tool that helps hospital cardiovascular teams assess how well their care pathways would hold up during a crisis. Developed through EU4Health funding with input from clinicians, patients, and policymakers across Europe, it guides teams through a four-step resilience evaluation.

Tokyo Metropolitan University researchers have detected laser-assisted electron scattering using circularly polarized light for the first time - a technical milestone that could reveal how atomic-scale chirality affects electron behavior. The signal matched theoretical predictions from Kroll-Watson theory.

A 12-week trial of the Melonga App found that men using the app doubled their time to ejaculation (from 61 to 125 seconds), with 22% no longer meeting criteria for premature ejaculation. The CLIMACS study, presented at the EAU Congress 2026, is the first to test an app-based treatment for the condition.

A juvenile female fisher traveled 118 kilometers from Durham to Lincoln, New Hampshire - the longest dispersal ever recorded for the species - through deep winter snow. The finding, published in Northeastern Naturalist, underscores the need for connected forest habitats as fisher populations decline.

Indiana has signed House Bill 1266, requiring data science integration across all K-12 subjects and creating a dedicated high school data science track covering AI engineering and computer science. The law follows a statewide summit and aims to replicate Indiana's jump to sixth nationally in reading.

A single injection of self-amplifying RNA into skeletal muscle produced a cardiac repair hormone called ANP that reduced scarring and improved heart function across multiple animal models, including aged mice and diabetic animals, for at least four weeks.

Research across China and North America found that abusive supervision triggers organizational dehumanization - making employees feel like tools rather than people - which drives burnout through inauthenticity and kills teamwork through perceived powerlessness.

Rice University developed a hydrogel from chitosan - a crustacean shell polymer - that encapsulates electroactive bacteria near an electrode, solving the mediator loss problem in liquid environments and enabling a living sensor that detected sakacin P in milk.

A Chemical Reviews paper from the University of Illinois describes how photonic substrates and nano-assemblies can detect microRNA signals associated with cancer development years before traditional diagnostic tools, by tapping into the previously ignored magnetic flux of electromagnetic radiation.

At the Precision Medicine World Conference 2026, Insilico Medicine's Alex Zhavoronkov chaired the aging and longevity track alongside epigenetic clock pioneer Steve Horvath, a decade after receiving the conference's Emerging Company Award for early AI drug discovery work.

Duke engineers demonstrated that ultrasound-burst microbubbles can create nanoscopic pores in cancer cell membranes, allowing delivery of PROTAC drugs too large to enter cells normally - killing 50% of cancer cells while 99% of healthy cells survived.

By exposing individual fireflies to blinking LED lights in pitch darkness, CU Boulder researchers derived the mathematical rules that allow thousands of Photuris frontalis to flash in unison - insights that could improve swarm robotics.

The American Meteorological Society and four partner organizations issued a statement opposing the removal of a climate science chapter from the federal judicial reference manual, warning it could limit courts' access to established scientific evidence and discourage expert participation.

Americans over 65 would travel an average of 68 minutes for primary care, 113 minutes for a diagnostic test, and 128 minutes for a specialist - but those in poor health, large cities, or with transportation barriers are far less willing to make the trip.

University of Utah researchers discovered that the Overdrive gene acts as a quality-control checkpoint during sperm development in Drosophila, and that selfish chromosomes from two different species independently hijack this system to kill competing sperm.

A King's College London review of 35 studies covering 52,584 participants with an average age of 17 found that problematic smartphone use was significantly associated with disordered eating behaviors and body dissatisfaction, with the link especially strong above seven hours of daily use.

Researchers propose 'just-shoring' as an alternative to current on-shoring, re-shoring, and friend-shoring strategies for critical minerals, arguing that without enforceable community governance rights, the clean energy transition risks replicating fossil fuel-era injustices.

A new manufacturing method using an IL-7/IL-15/IL-21 cytokine scaffold produced CAR-T cells that were more than 50% T memory stem cells - compared to under 5% with standard protocols - enabling sustained tumor control and HIV suppression in mouse models.

Scientists at KTH Royal Institute of Technology and Kinetic Chemistry Research have made the first direct observation of tetroxides - fleeting, oxygen-rich molecules assumed to exist for 70 years but never seen - finding they survive 0.2 to 200 milliseconds in ordinary air.

Using afterimages as a tool, Berlin researchers found that the brain predicts the visual consequences of eye movements with striking accuracy - reaching 94% of the true shift - but consistently falls slightly short, revealing a built-in bias in visual perception.
