This hybrid approach accurately predicts air pollution and corrects multi-day errors without violating the laws of physics, minimizing the unfeasible guesses often made by pure AI systems. Every day, millions of people rely on air quality forecasts to protect their health, while cities depend on them to trigger emergency pollution responses and emission controls. Yet delivering forecasts that are both pinpoint-accurate and scientifically explainable has long posed a daunting dilemma. Traditional chemical transport models simulate atmospheric physics and chemistry by calculating governing equations but are severely constrained by unpredictable human emissions. Meanwhile, purely data-driven artificial intelligence (AI) has advanced rapidly, but pure AI models lack physical common sense: they frequently produce erratic, physically unfeasible concentration swings, fail during unprecedented weather extremes, and operate as opaque black boxes that cannot diagnose why errors occur.

Bioengineer.org news storyFor people living with HIV, modern antiretroviral therapy can suppress the virus to levels below what standard laboratory tests can detect. Yet some patients on long-term treatment experience a curious phenomenon: a single test result showing a small, transient amount of virus in the blood, followed by an immediate return to undetectable levels. These events, known as viral blips, have puzzled clinicians and researchers for years, raising questions about whether they represent harmless statistical noise, brief bursts of viral production from hidden reservoirs, or early warnings of impending treatment failure. A new nationwide Swedish study, published in BMC Infectious Diseases, offers one of the most comprehensive answers to date. Drawing on the Swedish national InfCareHIV cohort, researchers analyzed data from 4,210 treatment-naïve adults who began antiretroviral therapy from 1 January 2007 onward, with follow-up data extracted through 30 September 2020. The median observation time was 5.5 years, with some individuals followed for as long as 13.7 years.

European Medical Journal news storyPeople living with HIV may experience subtle changes in heart muscle function even when conventional measures of cardiac performance remain normal, according to findings from a systematic review and meta-analysis. Researchers identified significantly impaired global longitudinal strain (GLS) among people with HIV compared with HIV-uninfected individuals, despite preserved left ventricular ejection fraction (LVEF) in both groups. The findings suggest that speckle-tracking echocardiography (STE) could provide additional information about early myocardial dysfunction in this population. Read the full news story here.

Among cancer patients, the high financial cost of cancer care is a prevalent problem. This financial burden is also associated with potentially harmful behavioral strategies that patients might use to cope with costs, such as delaying or forgoing treatment and skipping medications. Collectively, researchers refer to this impact as financial toxicity.
