Researchers have uncovered a tiny but powerful protein that helps keep our cells’ energy factories humming – a discovery that could spark new approaches to tackling obesity and age-related decline. Scientists at the Salk Institute in La Jolla found that a “microprotein” in mouse fat cells plays a critical role in maintaining healthy mitochondria , the structures that generate energy in our cells. By preserving mitochondrial function, this diminutive protein helps cells burn fuel efficiently, which in turn could influence body weight and the aging process. The findings shine light on how molecular biology connects to everyday health, opening the door to science-backed strategies for better metabolism and longevity.

Hyperuricemia occurs when the body accumulates too much uric acid because humans lack the enzyme uricase, which normally breaks down purines. A recent review led by Weizheng Zhang explains that high uric acid can develop through a combination of genetic variations (such as differences in genes for uric‑acid transporters and enzymes) and lifestyle factors. Purine‑rich foods (organ meats, red meat, some seafood and beer), obesity, impaired kidney function and dehydration all contribute to this imbalance. When excess uric acid crystallizes, it can trigger gout and raise the risk of cardiovascular disease, metabolic syndrome and kidney problems.
The review highlights that lifestyle changes are central to preventing and managing hyperuricemia. Dietary adjustments—such as reducing intake of purine‑dense foods, alcohol and sugar‑sweetened beverages—lower uric‑acid production, while a diet rich in fruits, vegetables and whole grains supports overall metabolic health. Moderate exercise helps with weight management and insulin sensitivity, but intense workouts can temporarily raise uric‑acid levels. Good hydration dilutes uric acid and promotes its excretion, and adequate sleep and stress management further support metabolic balance.
On the molecular side, variations in genes that encode uric‑acid transporters (SLC2A9, ABCG2) and enzymes such as xanthine oxidase can make some individuals more susceptible to hyperuricemia. Emerging research suggests that the gut microbiome plays a role in uric‑acid metabolism, hinting that probiotics or fiber‑rich diets may help regulate levels. Advances in imaging and omics technologies offer more precise diagnostic tools and may enable personalized treatments in the future, but for now, the cornerstone of care remains holistic lifestyle modification.
