PITTSBURGH, Jan. 12, 2026—Scripted television often shows outdated CPR techniques for lay people, potentially fueling misconceptions that could delay bystanders’ lifesaving interventions in the crucial moments after a real-life cardiac arrest. That’s according to University of Pittsburgh School of Public Health and School of Medicine researchers in the first analysis of TV depictions of bystander CPR, published today in Circulation: Population Health and Outcomes.

Shedding pounds almost invariably brings health benefits. But until now, it has been unclear to what extent weight loss also restores the health of the fat tissue itself. A new study from University of Southern Denmark offers insights into the profound changes in fat tissue in response to weight loss.

Japanese researchers have developed a living sensor display that turns engineered skin into a biological monitor, visually indicating internal inflammation without requiring blood sampling.

A new interdisciplinary study led by researchers from Nanyang Technological University, Singapore (NTU Singapore), with collaborators from the City University of Hong Kong, has found that El Niño events significantly reduce life expectancy across high-income Pacific Rim countries, resulting in economic losses of up to US$35 trillion by the end of the 21st century.

Using over six decades of mortality records from 10 high-income Pacific Rim countries, the research team shows that El Niño is a persistent driver of health and economic loss, not just a short-term weather anomaly. El Niño-driven climate extremes, such as heatwaves and air pollution, disrupt healthcare systems and raise long-term mortality risks, particularly among vulnerable populations.

The research, published in the scientific journal Nature Climate Change and part of NTU’s Climate Transformation Programme, shows that El Niño events not only cause immediate health impacts but also persistently slow long-term improvements in mortality rates, leading to enduring reductions in life expectancy.
