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.

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.

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 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.

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.

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 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.

CONCLUSIONS: This study challenges the prevailing assumption that the "digital divide inevitably isolates the older adults from participating in a digitized society." By integrating digital technologies into older adults care services, we demonstrate that smart elderly care is positively associated with bridging technological barriers and addressing the unmet needs of aging populations. These findings further propose a synergistic mechanism-policy innovation, technological adaptation, and...

CONCLUSIONS: Multidomain predictors spanning objective movement behaviours, body-composition indicators, and built-environment measures showed value for identifying education-stratified MoCA-defined MCI in community-dwelling older adults. LightGBM achieved the best overall performance among the candidate models. These findings support the potential utility of integrating behavioural, biological, and environmental information for community-based cognitive-risk stratification, although external...

A child psychologist says grandparents are more important than ever as youth mental health challenges continue to rise. He argues that children need supportive relationships, meaningful conversations, and a sense of purpose—not just pressure to achieve. Grandparents can help by listening, encouraging, and creating positive experiences that strengthen emotional resilience.

Scientists have uncovered a surprising new genetic cause of a rare movement disorder after analyzing nearly 3,000 patients with conditions affecting coordination and muscle control. The team identified mutations in a gene called CD99L2, previously linked only to the immune system, and showed that it plays an essential role in keeping nerve-cell communication running smoothly.

A new experimental vaccine developed by Scripps Research could offer a powerful new way to prevent fentanyl overdoses by stopping the drug before it reaches the brain. Rather than targeting only fentanyl itself, the vaccine trains the immune system to recognize a broad range of fentanyl-related designer drugs, including some of the most dangerous variants.

A new nature-inspired membrane uses perfectly uniform one-nanometer pores to filter molecules with remarkable precision. The technology could transform industries such as pharmaceuticals and textiles by reducing energy consumption, improving water reuse, and delivering separation performance far beyond current filters.

A low-calorie fasting-style diet significantly reduced inflammation linked to gum disease in a small clinical study. The findings suggest that what people eat may influence gum health almost as much as what they do with a toothbrush.

Researchers discovered that mutations linked to blood cancers may help trigger Alzheimer’s disease by creating overly inflammatory immune cells in the brain. The unexpected finding could lead to new blood-based screening methods and potential treatments borrowed from cancer medicine.

A new treatment that blocks an aging-related protein restored lost cartilage in old mice and helped prevent arthritis after knee injuries. Human cartilage samples showed similar signs of regeneration, raising hopes for a future drug that could repair joints instead of replacing them.
