“In this study, inulin supplementation was found to improve bowel symptoms and quality of life but had no superior effect on symptoms of depression and stool type compared to the placebo group,” wrote researchers at Mardin Artuklu University and other institutions in Turkey.Inulin is a soluble dietary fiber that acts as a prebiotic. In the colon, gut microbiota ferment inulin to produce beneficial metabolites, such as short-chain fatty acids, that support gut health and immunity. By supporting the microbiota, inulin can regulate colon transit time, stool consistency and the frequency of defecation. In addition, previous studies have suggested that inulin…

When it comes to running and walking gear, REI is the go-to destination. The major retailer has everything you need, whether you’re going for a multi-day hike with the family or training for your first marathon. If you’re anything like me, you might need some activewear upgrades now that the fall season is beginning to set in. Luckily, you can grab aptly timed price drops at the outdoor equipment giant.  I found REI sales on Hoka shoes, Yeti tumblers, Columbia jackets and more for up to 70% off. Start the new season with the right gear at the right price…

A new study finds that dietary carbohydrate quality is a promising factor in promoting healthy aging in women. This positive association challenges the idea that all dietary carbohydrates are negatively associated with chronic disease risk and all-cause mortality. Nutrition Insight speaks to the study’s co-author about how carbohydrates are important for older adults. “Consuming high-quality carbohydrates is favorably linked with healthy aging, and on the same line, consuming carbohydrates from refined sources, such as refined grains or added sugars, is linked to lower chances of becoming a healthy ager,” says Andres V. Ardisson Korat, Sc.D., Scientist II at Jean Mayer…

AnimalsMale and female C57BL/6 mice were kept on a 12-h light–dark cycle, provided with food and water ad libitum, and housed individually following headpost implants. A subset of mice used for optogenetic experiments were heterozygous for PV-ires-Cre (PV–Cre+; strain 008069, Jackson Laboratory) or for SST-ires-Cre (SST–Cre+; strain 013044, Jackson Laboratory). Mouse cohorts are detailed in Supplementary Table 2. All animals were between 3 and 6 months of age at the time of the experiment. All animal handling and experiments were performed according to the ethical guidelines of the Institutional Animal Care and Use Committee of the Yale University School of…

Europe’s health commissioner has warned that “unnecessary clinical trials” and bureaucracy are “not sending the right message” to the pharmaceutical industry, while other leaders stressed the need to “bring medicines to Europe” at the European Health Forum in Gastein, Austria.Their comments come amid an exodus of pharmaceutical investors from the UK and the threat of 100% tariffs on drugs sold to the US, which has reportedly led to plans to increase the amount the NHS spends on drugs.12Speaking to delegates last week, Olivér Várhelyi, health and animal welfare commissioner for the European Union, said that the “current regulatory environment does…

Naked mole-rats are well known for both their wrinkly appearance and for their unexpectedly long lives. The source of this extended lifespan has been under scrutiny for decades. While many rodents are relatively short-lived—mice tend to live approximately four years—naked mole-rats can live nearly 10 times as long. Further, as different as they seem from the outside, the genetics of naked mole-rats are more similar to humans than the oft-used mouse model. This makes them especially useful for studying the underlying genetics behind their longevity and the possible applicability to human longevity understanding. Current research into the genetics behind the…

Nature, Published online: 08 October 2025; doi:10.1038/d41586-025-03235-wThe light frequency associated with changes in the energy state of atoms can be used to define the ticking of high-precision optical clocks. Experiments with ytterbium atoms have further enhanced the clocks’ precision by using a quantum amplification technique.

Studying regulatory mechanisms of acetogenic bacteria can help researchers identify and engineer microbes to more efficiently use carbon dioxide.Image credit:©iStock.com, koya79Rising levels of atmospheric carbon dioxide (CO2) represent an urgent global issue, with communities already experiencing more extreme weather because of a changing climate. One strategy that companies are exploring to reduce the level of this greenhouse gas is to capture it and store it deep underground.Byung-Kwan Cho and his group identify novel acetogens and explore their metabolic mechanisms to find those that could provide climate solutions.

Small experimental mouse is on the researcher’s hand [unoL/ iStock/ Getty Images Plus] In a significant advance for gene therapies targeting rare severe brain disorders, scientists at the Allen Institute have developed a new gene therapy that successfully reversed major symptoms of SYNGAP1-related disorders (SRD) in mice. The gene therapy, published in the journal Molecular Therapy, represents the first demonstration that SYNGAP1 gene supplementation can restore neurological function after symptoms have appeared. “Gene supplementation is providing a functional new copy of a defective gene, a strategy that has great potential for correcting diseases where a gene is completely missing or…
