Worldwide radiation dose in coronary artery disease diagnostic imaging

JAMA

2026-02-25

(Press-News.org) About The Study: Given increasing rates of coronary artery disease (CAD) worldwide, the findings of this study of marked variation in radiation dose to patients from diagnostic testing identify a critical need for training, standardized protocols, and updated equipment to reduce radiation worldwide. This especially affects patients in low- and middle-income countries and patients undergoing coronary computed tomography angiograph. There are therefore important opportunities to improve the quality of CAD diagnosis for patients across the globe.

Heat and pregnancy

2026-02-25

About The Article: Climate change is increasing the frequency and intensity of heat waves and the exposure of pregnant individuals to extreme heat. This article summarizes current evidence about risks to maternal health from ambient heat (hot weather, high indoor temperatures, and occupational exposures) and how these risks can be managed.

Superagers’ brains have a ‘resilience signature,’ and it’s all about neuron growth

2026-02-25

Brains of older adults with super healthy cognition grow more new neurons than those of their peers, according to a study from UIC, Northwestern University and the University of Washington. Researchers found that the brains of superagers — octogenarians with uncommonly nimble minds — were the most neuronally fertile, while those with Alzheimer’s disease had negligible new growth. “This is a big step forward in understanding how the human brain processes cognition, forms memories and ages. Determining why some brains age more healthily ...

New research sheds light on why eczema so often begins in childhood

2026-02-25

[New York, NY [February 25, 2026]—A team of researchers at the Icahn School of Medicine at Mount Sinai, Weill Cornell Medicine, and other institutions have uncovered a key biological explanation for why eczema so often starts in childhood. The study, in young mice, found that some types of immune cells in early-life skin are more reactive than those in adults, a difference that may help explain why children are more vulnerable to inflammation and allergic skin disease. The findings suggest that early childhood represents a critical window for immune-driven ...

Small models, big insights into vision

2026-02-25

Small models, big insights into vision Understanding how the brain processes what we see is one of the central questions in neuroscience. Our visual system is incredibly powerful, able to recognize faces, objects, and scenes with ease, yet the details of how individual neurons respond to images remain complex and difficult to study. A new study published in Nature shows that it is possible to capture these responses using models that are both highly accurate and far simpler than previous approaches. The team began with a large computer model designed to predict how neurons in the visual cortex ...

Finding new ways to kill bacteria

2026-02-25

The scientists report their findings in the February 26 issue of the journal Nature. The lead author of the paper is Yancheng Evelyn Li, a graduate student in the lab of Bil Clemons, the Arthur and Marian Hanisch Memorial Professor of Biochemistry at Caltech, who is the corresponding author. "Evolution is powerful, and in bacteria, resistance to antibiotics develops quickly. This means that we now deal with bacteria that are resistant to all the medicines that we have," Clemons says. "In the USA alone, tens of thousands of people die every year from antibiotic-resistant bacterial infections, ...

An endangered natural pharmacy hidden in coral reefs

2026-02-25

Coral reefs are teeming with life: they are home to over a third of all marine animal and plant species on Earth, despite covering less than one percent of the ocean floor. However, this immense diversity is under threat from rising ocean temperatures. Since the 1950s, half of the world’s coral population has already disappeared. Beyond the reef’s visible inhabitants, countless microorganisms are also under threat. These often live in symbiosis with corals, sponges and other reef dwellers, which benefits them ...

The Frontiers of Knowledge Award goes to Charles Manski for incorporating uncertainty into economic research and its application to public policy analysis

2026-02-25

The BBVA Foundation Frontiers of Knowledge Awards in Economics, Finance and Management has gone in this eighteenth edition to Charles F. Manski for his pioneering contributions to the measurement of uncertainty in economic research and its application to public policy analysis. The professor at Northwestern University (Chicago, United States) is described by the committee as a “foundational figure” in the development of modern methods that have transformed how economists infer conclusions from data, report degrees of uncertainty in their models, ...

As health care goes digital, patients are being left behind

2026-02-25

Patients are now expected to navigate much of their care online — from seeing their doctor on a screen to booking appointments, refilling prescriptions, and checking test results through health care portals.  Yet, according to a new study by UC San Francisco, most health systems are skipping a crucial step: asking whether their patients have the access and skills to use these digital tools.  The researchers surveyed nearly 150 clinicians and informatics leaders from health care systems across the country during the first half of 2024. Just 44% said they asked their patients if they could use digital devices. Among the ...
