An ambitious effort to create a neurophysiological paradigm to explain near-death experiences has failed to capture many fascinating and often perplexing aspects of people's brushes with death, top University of Virginia experts argue in a new paper. https://medicalxpress.com/news/2026-01-death-scientists.html Wed, 14 Jan 2026 10:04:43 EST news687607450 Health officials want you to think twice before buying one of those brightly colored little bottles often sold at gas stations, convenience stores and smoke shops. https://medicalxpress.com/news/2025-06-gas-station-heroin-technically-illegal.html Sun, 15 Jun 2025 07:12:53 EDT news669190359 A multidisciplinary team led by the University of Liège has proposed a unified neuroscientific model explaining the mechanisms behind near-death experiences (NDEs), drawing on converging empirical findings across neurobiology, psychology, and evolutionary theory. https://medicalxpress.com/news/2025-04-neuroscientific-death-physiological-pattern.html Wed, 02 Apr 2025 10:00:01 EDT news662804575 Reiterating a warning first issued in November, the U.S. Food and Drug Administration is urging Americans to stay away from supplements containing tianeptine, known on the street as "gas station heroin." https://medicalxpress.com/news/2024-01-fda-issues-tianeptine-products-seizures.html Thu, 25 Jan 2024 13:37:03 EST news625412221 A new paper published online in the Annals of the American Thoracic Society discusses how smoking may affect risk for COVID-19 and the types of research that are needed to better understand the link between smoking and COVID-19 risk. https://medicalxpress.com/news/2021-03-paper-covid-.html Mon, 01 Mar 2021 12:15:19 EST news533823315 In a proof-of-concept experiment, researchers from Johns Hopkins Medicine say they have successfully used microscopic man-made particles to predict the severity of patients' chronic obstructive pulmonary disease (COPD) by measuring how quickly the particles move through mucus samples. The technique, say the researchers, could eventually help doctors deliver more effective treatments sooner. https://medicalxpress.com/news/2019-09-nanoparticles-wiggling-mucus-severe-copd.html Mon, 30 Sep 2019 10:26:53 EDT news489058006 In a study of mice, researchers at Johns Hopkins have identified a new molecular pathway involved in the growth of tiny air sacs called alveoli that are crucial for breathing. The scientists say their experiments may lead to the first successful treatments to regrow the air sacs in people who suffer from diseases such as emphysema in which the air sacs have been destroyed by years of smoking. The work may also suggest new therapy for premature infants born before their lungs are fully developed. https://medicalxpress.com/news/2013-02-air-sacs-mouse-emphysema-growth.html Thu, 14 Feb 2013 17:10:01 EST news280083445 Chronic obstructive pulmonary disease (COPD) is among the most common causes of death in the US. It is a smoking-related disease for which there are currently no disease-altering therapies. However, hope that one could be developed is now provided by the work of Enid Neptune and colleagues, at Johns Hopkins University, Baltimore, in a mouse model of lung disease caused by exposure to cigarette smoke. https://medicalxpress.com/news/2011-12-blood-pressure-drug-limits-cigarette.html Mon, 19 Dec 2011 12:00:02 EST news243517235
