PFAS, or "forever chemicals," are widespread in the environment and can accumulate in our bodies. These synthetic chemicals infiltrate our food, water, household products, and even our bodies. They resist breakdown and persist in the environment and the human body, earning the label "forever chemicals". Specific strains of human gut bacteria can effectively absorb these "forever chemicals", trapping them within their cells. The full impact of PFAS on health remains unclear, but studies have connected these chemicals to cancer, heart disease, reduced fertility, and other adverse effects.
While no method has been found to destroy PFAS, recent discoveries suggest potential strategies for removing these harmful "forever chemicals" from our bodies, where they cause the most damage. Scientists are investigating targeted probiotic supplements to increase PFAS-absorbing bacteria in the gut, aiming to strengthen the body’s natural capacity to eliminate these toxic chemicals before they build up to harmful levels.
The study has identified nine bacterial species capable of capturing up to 75% of these toxic compounds. When introduced into mice, within minutes these bacteria quickly absorbed PFAS chemicals. As the bacteria were expelled through the gut, they carried the forever chemicals out with them in waste. The study showed they consistently removed a stable proportion of the toxins, indicating their potential as a natural gut filter.
Scientists aim to create probiotic supplements to enhance these beneficial bacteria, providing a novel approach to lowering PFAS levels in humans. However, although encouraging, these findings have not yet been directly tested in human subjects. The next phase involves conducting human clinical trials to determine if probiotics can boost the levels of PFAS-absorbing bacteria in the gut and to evaluate the safety of these interventions.

Brain aging encompasses the gradual biological and functional shifts in the brain as we age, changes that may or may not affect cognitive performance. A recent study explored whether creativity offers more than just enjoyment or emotional benefits, investigating if it provides tangible biological advantages for brain health.
Could your meal timing weaken your bones? A recent study suggests that habits like skipping breakfast or eating late-night dinners may heighten the risk of developing osteoporosis. This pioneering research is the first to highlight a clear link between such eating patterns and an increased chance of bone fractures due to osteoporosis.
While melanoma and squamous cell carcinoma are generally slow-growing and rare, a new study finds that people with tattoos face a greater risk of developing melanoma. While tattoos raised melanoma risk, they did not increase the odds of squamous cell carcinoma, another sun-driven skin cancer that, unlike the much more lethal melanoma, arises from different skin cells.
