The secret behind smoother, better-tasting protein shakes
A new whey protein manufacturing technique could make protein shakes taste better and feel smoother in the mouth. Researchers traced unwanted bitterness to concentrated minerals and found a way to remove them without sacrificing the improved texture.

Reversing prediabetes cuts risk of deadly heart problems by 58%
Bringing blood sugar levels back to normal may dramatically reduce the danger posed by prediabetes. Researchers found that people who reversed prediabetes cut their risk of cardiovascular death or hospitalization for heart failure by 58% and lowered their chances of major heart problems such as heart attacks and strokes by 42%. The benefits lasted for decades and were seen across large long-term studies in both the U.S. and China.
Trajectory of frailty among the older people in a community setting: A cohort study from the Shizuoka Kokuho Database
CONCLUSIONS: These findings highlight severe frailty as a late high-risk state and may inform age- and sex-specific frailty risk stratification and care planning.
Cellular senescence in ischemic stroke: cell-type specificity, temporal dynamics, and response to therapeutic interventions
Increasing experimental and clinical evidence indicates activation of cellular programs resembling senescence and senescence-associated secretory phenotype signaling after stroke. However, a central challenge is definitional: in injured brain tissue, many senescence-associated features overlap with acute stress responses, transient cell-cycle perturbations, and reactive glial or vascular programs, complicating interpretation across models, time points, and cell types. Here, we synthesize the...
Nacre extract attenuates age-related functional and tissue alterations under post-onset intervention conditions in two murine aging models
Aging is accompanied by the accumulation of senescent cells and chronic low-grade inflammation, which together contribute to functional decline and tissue remodeling across organs. We previously reported that long-term nacre extract supplementation can delay age-related deterioration when initiated early; however, whether it can provide benefit under post-onset intervention conditions remains unclear. Here, we evaluated a water-soluble nacre extract derived from Pinctada fucata using (i)...
Awareness of active ageing and its association with quality of life among older adults in a tertiary care setting in Saudi Arabia: a cross-sectional study
CONCLUSIONS: The study findings showed a low level of awareness of the concept of active ageing among older adults in a tertiary care clinic in Saudi Arabia. Greater awareness of active ageing was positively associated with better quality of life among older adults, despite limited familiarity with the concept. These findings highlight the importance of integrating active ageing education into healthcare services and public health initiatives to support healthier and more fulfilling ageing...

Scientists found a surprising problem with sugar-free diets
A surprising new study suggests that completely eliminating sugar may backfire. Mice on a sucrose-free low-fat diet showed worse blood sugar control, increased inflammation, disrupted gut bacteria, and signs of fatty liver compared with mice that consumed some sucrose. Researchers say the results highlight the importance of a balanced diet and a healthy gut microbiome rather than focusing solely on cutting out sugar.
People taking GLP-1 weight loss drugs like Ozempic started moving less
People taking popular weight-loss drugs such as Ozempic, Wegovy, Mounjaro, and Zepbound may be losing pounds, but they could also be moving less. Researchers analyzing Fitbit data found that daily step counts and exercise levels dropped after people started these medications, despite successful weight loss. Because the drugs can reduce muscle mass along with fat, the decline in physical activity raises concerns about preserving strength and long-term health.
Why middle age is becoming a breaking point in the U.S.
A new international study finds that middle-aged Americans are lonelier, more depressed, and experiencing worse memory and health than earlier generations. Researchers say growing financial strain, weaker social supports, and chronic stress may explain why the U.S. is falling behind other wealthy nations.
Your brain can keep improving into your 90s, study finds
A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health, including thinking clarity, emotional well-being, and sense of purpose.
Learning a musical instrument in your 70s could help protect memory
Learning a musical instrument later in life may help keep the brain younger for longer. In a four-year study, older adults who continued practicing maintained their memory performance and showed less age-related brain shrinkage than those who quit. The benefits were especially noticeable in brain regions tied to memory and learning.
