Catheter ablation and oral anticoagulation for secondary stroke prevention in atrial fibrillation

JAMA Neurology

2026-03-02

(Press-News.org) About The Study: In patients with atrial fibrillation and a recent stroke history, standard therapy plus catheter ablation did not significantly reduce the risk of the primary composite end point. The observed event rate was lower than anticipated, suggesting that the study was underpowered to detect clinically meaningful differences.

A new theory of brain development

2026-03-02

Your brain begins as a single cell. When all is said and done, it will house an incredibly complex and powerful network of some 170 billion cells. How does it organize itself along the way? Cold Spring Harbor Laboratory neuroscientists have come up with a surprisingly simple answer that could have far-reaching implications for biology and artificial intelligence. Stan Kerstjens, a postdoc in Professor Anthony Zador’s lab, frames the question in terms of positional information. “The ...

Pilot clinical trial suggests low dose lithium may slow verbal memory decline

2026-03-02

Lithium—a decades-old treatment for bipolar disorder—may hold potential neuroprotective benefits beyond mood stabilization. An exploratory clinical trial from the University of Pittsburgh suggests that low‑dose oral lithium may help slow the decline of verbal memory, or ability to remember and recall words and sentences, in older adults with mild cognitive impairment, particularly among those with evidence of amyloid beta—one of the hallmark biomarkers of Alzheimer’s disease. The study, ...

Bioprinting muscle that knows how to align its cells just as in the human body

2026-03-02

Building functional human muscle in the laboratory has long been a goal of regenerative medicine, but one stubborn obstacle remains: real muscle is not just a mass of cells. Its strength and function depend on exquisitely ordered myofibers, all aligned in precise directions that vary from one muscle to another. Reproducing that internal order has proved far harder than shaping muscle tissue into the right external form. Published in the International Journal of Extreme Manufacturing, a research team from Xi'an Jiaotong University has now found a way to solve both problems at once. By using electric forces during the ...

A hair-thin fiber can read the chemistry of a single drop of body fluid

2026-03-02

Some of the most revealing signals about human health are carried in fluids that are almost impossible to measure. Tears, cerebrospinal fluid, and prostate fluid appear only in tiny volumes, yet their chemical composition can reflect inflammation, hydration, or disease. For decades, engineers have struggled to analyze these fluids in real time, because most sensors require far more liquid than the body can easily provide. Researchers at Jilin University now report a way to measure the electrical conductivity of such fluids using volumes as small as 50 nanoliters. The device, reported in the International Journal of Extreme Manufacturing, is an optical fiber probe no thicker than a human ...

SwRI develops magnetostrictive probe for safer, more cost-effective storage tank inspections

2026-03-02

SAN ANTONIO — March 2, 2026 — Southwest Research Institute (SwRI) has created a magnetostrictive transducer (MST) probe that uses ultrasonic guided wave technology to detect corrosion in storage tanks, a process that normally requires emptying the tank and checking for corrosion manually. SwRI’s probe attaches to the outside of a storage tank, resulting in a more cost-effective and efficient method of corrosion detection. The SwRI MST 8x8 is a flexible strip of eight ultrasonic sensors that generate acoustic waves along a structure. The technique identifies anomalies when the waves are ...

National report supports measurement innovation to aid commercial fusion energy and enable new plasma technologies

2026-03-02

To operate fusion systems safely and reliably, scientists need to monitor plasma fuel conditions and measure properties like temperature and density that can affect fusion reactions. Making these measurements requires specialized sensors known as diagnostics. A new report sponsored by the U.S. Department of Energy (DOE) recommends increased investment in America’s fusion diagnostic capabilities, a critical new technology that could provide DOE and Congress with information to speed up the delivery of commercial fusion power plants. The report was produced as part of the DOE’s ...

Mount Sinai, Uniformed Services University join forces to predict and prevent diseases before they start

2026-03-02

NEW YORK, NY (March 2, 2026)—What if doctors could tell you a disease was coming years before you felt a single symptom—and stop it in its tracks? That is the goal of a sweeping new research initiative launched by the Icahn School of Medicine at Mount Sinai in collaboration with the Uniformed Services University of the Health Sciences (USU) and the Henry M. Jackson Foundation for the Advancement of Military Medicine (HJF). The project, called “ORIGIN: Omics to Characterize Preclinical Stages of Non-Infectious Diseases,” brings together 10 specialties across Mount Sinai Health ...

Science of fitting in: Do best friends or popular peers shape teen behavior?

2026-03-02

As children enter adolescence, peers become a dominant force in their lives. With adult supervision waning, teens look to agemates for guidance on how to act, think and fit in. But who matters most –friends or the popular classmates? A groundbreaking longitudinal study from Florida Atlantic University reveals that peer influence is not a monolithic process. Instead, different types of peers exert influence over entirely different domains of a child’s life. Researchers at FAU and collaborators at Mykolas Romeris University (Lithuania) conducted a long-term study to directly compare these two sources of influence. The study, published in the journal Development ...

USF study: Gag grouper are overfished in the Gulf; this new tool could help

2026-03-02

Anglers along the Gulf Coast have long prized the hard-fighting, mild-tasting gag grouper (Mycteroperca microlepis), but some may have been surprised over the past few years by shortened seasons for this desirable reef fish. Due to concerns about the population of the species, the gag season lasted just 41 days in 2023, 15 days in 2024, and 14 days in 2025 — far shorter than the six-month seasons in previous years. A new paper by researchers from the University of South Florida (USF) and Florida Fish and Wildlife Conservation Commission (FWC) may assist resource managers who make tough decisions about the lengths of fishing ...

New study from Jeonbuk National University finds current climate pledges may miss Paris targets

2026-03-02

International efforts to tackle climate change reached a major milestone with the Paris Agreement, adopted by more than 190 countries. The agreement aims to limit the average global temperature rise to well below 2 °C, preferably to 1.5 °C. However, questions remain as to whether current national climate pledges are sufficient to meet these goals. Against this backdrop, a new collaborative study by Assistant Professor Taeyoung Jin of Jeonbuk National University and researchers from Pusan National ...
