Fish that stayed active and slept mostly at night tended to live longer, while those slowing down earlier lived shorter lives. Surprisingly, aging didn’t unfold smoothly but in sudden jumps between stages. The work suggests that tracking daily habits in humans could reveal early clues about how we age.

Fiber plays a powerful role in keeping the body healthy, from supporting digestion and feeding beneficial gut microbes to helping regulate blood sugar and cholesterol. Researchers say getting enough fiber may even lower the risk of conditions like obesity, diabetes, and certain cancers.

In a large national study of more than 3,800 Americans age 70 and older, those who received the shingles vaccine showed slower biological aging compared to those who didn’t. Researchers found lower levels of chronic inflammation and slower changes in gene activity linked to aging, suggesting the vaccine may calm the body’s “inflammaging” — the low-grade inflammation tied to heart disease, frailty, and cognitive decline.

While many preservatives showed no association, several widely used ones, including potassium sorbate, sulfites, sodium nitrite, and potassium nitrate, were tied to increased risks of overall cancer and specific types such as breast and prostate cancer. Tue, 27 Jan 2026 01:58:24 EST https://www.sciencedaily.com/releases/2026/01/260127010154.htm https://www.sciencedaily.com/releases/2026/01/260109080211.htm Foods that rely heavily on preservatives may be doing more than extending shelf life. In a large study spanning more than a decade, people with the highest intake of preservative additives were far more likely to develop type 2 diabetes. The increased risk appeared across many commonly used additives found in everyday processed foods. Researchers say the findings support advice to limit highly processed products when possible.

Scientists found that this “epigenetic drift” follows a clear pattern and appears in both aging intestines and most colon cancers. Some regions age faster than others, forming a patchwork of weakened tissue more prone to degeneration. Encouragingly, researchers showed this drift can be slowed—and partly reversed—by restoring iron levels or key cellular signals.

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.

The team used a gene knockout mouse model to help them study the effects of disrupting selenoprotein synthesis. This knockout negatively impacted hematopoietic stem cells and B cell-lineage immune cells, which was driven by the lack of selenoprotein-mediated fighting of lipid peroxides. These phenotypes mimic what is observed in age-related diseases, emphasizing the importance of selenoproteins in these disorders.

The results lead directly to the idea that modifying the diet has the potential to be a new weapon in the fight against antimicrobial resistance. And this does not require eating some exotic diet, but eating a diverse diet, adequate in fiber, a diet that some Americans already eat.

The researchers have also identified antioxidants that can be added to skin products to mop-up the harmful iron, thereby minimizing sun damage.

Examining cerebrospinal fluid samples from patients with cognitive impairment ranging from subjective impairment to a diagnosis of Alzheimer's disease, they found a shift in the profile of specialized liquid mediators from pro-resolving to pro-inflammatory.

The results showed that total fiber, and more specifically cereal fiber but not fruit or vegetable fiber, was consistently associated with lower inflammation and lower CVD incidence. Until now there had been limited data on the link between fiber and inflammation among older adults, who have higher levels of inflammation compared with younger adults.

They designed a fabric that works like a microphone, converting sound first into mechanical vibrations, then into electrical signals, similarly to how our ears hear.

The findings shed light on wasting mechanisms in advanced stage cancer patients, for whom prevalence of devastating skeletal muscle atrophy known generally as cachexia reaches 80 percent.

In a large-scale study, over 3500 Japanese adults completed a dietary survey and were then followed up for two decades. Adults who consumed more fiber, particularly soluble fiber, were less likely to go on to develop dementia. These findings may relate to interactions between the gut and the brain.
