Credit: THOM LEACH / SCIENCE PHOTO LIBRARY/ Getty Images A UCLA-led research team has identified a genetic system in gut bacteria that helps them adapt rapidly to the human gut microbiome, a finding that could change the current understanding of this vital component of human health and suggest new ways to enhance it as a method to treat a variety of diseases. The study, published in the journal Science, focused on how diversity-generating retroelements (DGRs), which carry collections of genes that work together to create random mutations in specific hotspots in bacterial genomes, accelerate bacterial evolution and allow the microbes…
Researchers noted both what did and didn’t surprise them about 2025’s Nobel Prizes.Image credit:© iStock, rrodrickbeilerAs this year’s Nobel Prize week comes to a close, the editors at The Scientist surveyed researchers on their reactions to the award winning research, specifically the Chemistry Nobel Prize honoring metal-organic frameworks and the Physiology or Medicine Nobel Prize for peripheral immune tolerance. Looking back at our poll of scientists’ Nobel Prize predictions from a couple weeks ago, the award-winning research certainly seems to have been a surprise to some! Read on to see what scientists are saying:Immunologists Celebrated Regulatory T cells’ WinMichael Mina,…

Sale listing on the dark web for nitazenes have gone up as listings for fentanyl (pictured) have gone down.Credit: Gary Coronado/Los Angeles Times/GettyResearchers who study trends in illicit drug use are concerned that sales of a potent class of synthetic opioids called nitazenes are on the rise globally.The opioid class of drugs includes heroin and morphine. Unlike those drugs, which are derived from naturally occurring opium, nitazenes are synthesized from scratch in a laboratory. The first nitazenes were developed as painkillers in the 1950s, but were never approved for medical use because they carried a high risk of dangerous side…
How Protein Plays a RoleLifting weights, however, can help you preserve muscle mass. It can act as a signal to retain and even gain muscle if paired with the right diet, according to the University of Maryland Medical System.The key is to track your protein intake as well as the magnitude of your calorie deficit.In your body, protein is broken down into amino acids, which are like building blocks. Your body reassembles those amino acids to build muscle and other tissues, helping you recover after a workout. But if you don’t eat enough, your body doesn’t have the building blocks…
Global consumption of plastics is on the rise, but only a small percentage of plastic waste is recycled. Credit: Justin Sullivan/GettyCrucial negotiations on what would have been the first ever global agreement to limit plastic pollution collapsed last month amid acrimony and distrust. This week, hopes for an agreement suffered another blow when Ecuador’s ambassador Luis Vayas Valdivieso resigned as chair of the intergovernmental negotiating committee (INC) for the treaty.Plastics pollution is surging — the planned UN treaty to curb it must be ambitiousAt the last INC meeting, held in Geneva in August, negotiations ran long into the night, but…
Neurodegenerative diseases remain difficult to detect and monitor with high precision. However, emerging sequencing-based methylation tools are enabling new ways to track the progression of these complex conditions. In this Inside Precision Medicine webinar, speakers will explore how analysis of cfDNA, powered by Oxford Nanopore Technologies, is advancing the detection and monitoring of neurodegenerative conditions such as Alzheimer’s and Parkinson’s. Researchers from Wasatch BioLabs will present a cfDNA methylation approach built from native-read whole-methylome models in brain tissue that expands the informative loci available for resolving cell-type signals, differentiating diseases, and tracking neuronal signals for therapeutic evaluation. Experts from Oxford…
