Per- and polyfluoroalkyl substances (PFAS) have become ubiquitous throughout the environment, and increasing evidence has demonstrated their deleterious effects. A group of smaller, fluorinated compounds are becoming replacements for these 'forever chemicals,' though research suggests the smaller versions could also be harmful. Now, a study reports that the levels of these substances in many indoor and human samples are similar to or higher than those of legacy PFAS.

Among people who report memory and thinking problems, some show no signs of a problem on standard tests, while others have subtle declines on their tests. A new study shows that people who have subtle problems with these tests may have an increased risk of developing mild cognitive impairment, which can be a precursor to dementia.

Pleural mesothelioma (PM) is mainly caused by asbestos exposure and characterized by poor prognosis and limited therapeutic options. A recent research study identified the oncoprotein YB-1 as an attractive therapeutic target in PM and demonstrates that indirect targeting of YB-1 is a promising approach to enhance sensitivity to chemo- and radiotherapy.

Under normal conditions, the floating macroalgae Sargassum spp. provide habitat for hundreds of types of organisms. However, the Great Atlantic Sargassum Belt (GASB) that emerged in 2011 has since then caused unprecedented inundations of this brown seaweed on Caribbean coastlines, with harmful effects on ecosystems while posing challenges to regional economies and tourism, and concerns for respiratory and other human health issues.
