Known as CAG-170, these microbes were found at lower levels in people with a range of chronic diseases. Genetic clues suggest they help digest food and support the broader gut ecosystem. Researchers say the discovery could reshape how we measure and maintain gut health.

Using advanced MRI scans and data from nearly 26,000 people, researchers identified two surprising fat patterns tied to faster brain aging, cognitive decline, and higher neurological disease risk. One involves unusually high fat buildup in the pancreas, even without much liver fat, while the other—often called “skinny fat”—affects people who don’t appear severely obese but carry excess fat relative to muscle.

Researchers have created a world-first database that tracks beneficial bacteria and natural compounds linked to immune strength, stress reduction, and resilience. The findings challenge the long-standing obsession with germs as threats and instead highlight the hidden health benefits of biodiversity. This shift could influence everything from urban design to environmental restoration.

It relies on nanoparticles that bind to tumor markers, making cancerous areas easier to identify. The system is far more sensitive than existing tools and could speed up cancer screening. Scientists believe it may help detect tumors earlier and reduce delays in diagnosis.

New research shows these systems can infer patient demographics from pathology slides, leading to biased results for certain groups. The bias stems from how the models are trained and the data they see, not just from missing samples. Researchers also demonstrated a way to significantly reduce these disparities.

These molecules change depending on diet, genetics, and shifts in the microbiome. Some even improved insulin response in liver cells when tested in the lab. The findings could open the door to new ways of preventing or managing obesity and diabetes.

Their findings reveal how shifts in gut microbial function — including inflammation, loss of protective species, and overactive metabolic pathways — may drive disease progression. Intriguingly, even “good” bacteria like Faecalibacterium prausnitzii and Akkermansia muciniphila can become harmful under certain conditions.

The material forms a mineralized layer that halts decay and restores strength, outperforming traditional fluoride. Made from sustainable sources like hair, it could soon be available in toothpaste or gels. The discovery could transform dentistry by turning waste into a powerful tool for regeneration. Mon, 10 Nov 2025 12:04:50 EST https://www.sciencedaily.com/releases/2025/11/251110021058.htm https://www.sciencedaily.com/releases/2025/10/251024041819.htm ASU scientists found that people whose gut microbes make more methane extract more calories from fiber-rich foods. Methanogens help the microbiome turn fiber into energy by consuming hydrogen and producing methane. Using advanced metabolic chambers, researchers measured how diet and gut chemistry interact, showing that methane may signal efficient digestion. The work could lead to personalized diets based on individual microbiomes.

A new study shows that immersive virtual nature dramatically reduces pain sensitivity almost as effectively as medication. Researchers at the University of Exeter found that the more present participants felt in these 360-degree nature experiences, the stronger the pain-relieving effects. Brain scans confirmed that immersive VR scenes activated pain-modulating pathways, revealing that our brains can be coaxed into suppressing pain by simply feeling like we re in nature.

Using a 24-hour wearable device, researchers achieved nearly 97% accuracy in identifying people based solely on how they breathe through their nose. Even more intriguingly, these respiratory signatures correlated with traits like anxiety levels, sleep cycles, and body mass index. The findings suggest that breathing isn t just a passive process it might actively shape our mental and emotional well-being, opening up the possibility of using breath training for diagnosis and treatment.

Researchers have now substantiated that certain skin bacteria can protect us from the sun's ultraviolet (UV) radiation specifically by metabolizing cis-urocanic acid using an enzyme called urocanase. This enables the skin's ability to fine-tune how it responds to UV radiation. The findings demonstrate the ability of the skin microbiome to remodel host immune functions.

Surprisingly, simply watching nature videos was enough to relieve pain. Using functional magnetic resonance imaging, the researchers found that acute pain was rated as less intense and unpleasant when watching nature videos -- along with a reduction in brain activity associated with pain. The results suggest that nature-based therapies can be used as promising complementary approaches to pain management.

The first step is often a blood test for prostate-specific antigen (PSA). If PSA levels exceed a certain threshold, the next step typically involves taking a tissue sample for analysis. Another option is to use magnetic resonance imaging (MRI) to search for signs of a tumor before deciding whether a biopsy is necessary, reserving biopsies only for cases where abnormalities are detected. Researchers at conducted a study to determine whether this MRI-first approach is safe over the long term. Their findings show that this strategy poses no additional risk to patients for at least three years.

Using a novel technique of cell staining, forensic science experts have tested 100 people to confirm how people shed varying levels of touch DNA, from very low to very high.

A team of researchers aims to bring heart failure screening from the lab to the home with a point-of-care electrochemical biosensor prototype that measures levels of two biomarkers for heart failure in as little as 15 minutes from just a drop of saliva.

This could help clinicians avoid overtreating patients whose disease is unlikely to progress.

The forensic identification technique is based on the analysis of a skull (post-mortem) and photographs of the person's face (ante-mortem). It represents a major step in making objective decisions that are based on the ability to quantify the probability that a skull matches the photographs being examined.

The study shows how plants can be programmed to produce a diverse array of beneficial sugars found in human breast milk. The findings could lead to healthier and more affordable formula for babies, or more nutritious non-dairy plant milk for adults.

Some of these changes can have little effect, but others can lead to diseases, including cancer. Now, a new study introduces an original technique, called HiDEF-seq, that can accurately detect the early molecular changes in DNA code that precede mutations.
