Low-fat vegan diet helps people lose weight without eating less
A low-fat vegan diet may help people lose weight without counting calories, shrinking portions, or feeling constantly hungry. In a 16-week clinical trial, people eating mostly fruits, vegetables, grains, and legumes consumed about 357 fewer calories per day even though the total amount of food they ate barely changed.
Scientists uncover the hidden nerve network fueling breast cancer
Researchers have uncovered a surprising way triple-negative breast cancer may turn the body against itself. Tumors appear to recruit macrophages—immune cells normally involved in healing and fighting infection—and use them to release a protein called BDNF that draws nerves into the tumor. Those nerves may then help the cancer grow, resist treatment, and potentially spread.
Mesenchymal Stromal Cell Rejuvenation Strategies to Enhance Clinical Translation in Cell Therapy
Cell therapies represent a promising frontier in modern medicine. Mesenchymal stromal cells (MSCs) constitute a valuable source due to their minimal ethical concerns, low immunogenicity, negligible tumorigenicity in vivo, and robust paracrine activity mediated by the secretion of anti-inflammatory and angiogenic factors. Despite these advantages, MSCs undergo rapid replicative senescence accompanied by a progressive loss of stemness markers and functional potency. In this context, cellular...
Financial Decision-Making, Financial Literacy, and Cognitive Function: Evidence From the PATH Through Life Study
CONCLUSIONS: Better cognitive function was associated with higher objective financial literacy, whereas subjective financial literacy showed no association with cognitive performance. These findings highlight the importance of cognitive function for financial literacy in later midlife to early older age adults.
TRF2 Recovers Ischemic Postconditioning Cardioprotection in Aged Myocardiocytes by Regulating CSNK2A2 Localization and FUNDC1 Dephosphorylation
Ischemic postconditioning (I/Post), which is an effective intervention by activating endogenous cardioprotective pathways, recovers ischemia/reperfusion injury. However, this intervention is not as effective in older patients, and its mechanism needs to be further investigated. In this study, we found that myocardial telomeric repeat binding factor 2 (TRF2) protein expression in male aged mice (18 months of age) was lower than that in male adult mice (4 months of age). After ligation of the...
An ANGPTL8-AKT2-mTOR Axis Drives Adipose Senescence and Aging-Related Functional Decline
Adipose tissue senescence is increasingly recognized as a key driver of systemic aging and age-related functional decline, yet the endocrine regulators that actively promote this process remain poorly defined. Angiopoietin-like protein 8 (ANGPTL8) is a metabolic factor implicated in lipid metabolism and inflammation and has been associated with multiple aging-related disorders. However, its direct role in adipose tissue senescence and organismal aging remains unclear. Here, we identify ANGPTL8...

Scientists tracked kids for 8 years — the screen time result was unexpected
An eight-year Finnish study found that children who spent more time on screens tended to show better cognitive processing as teenagers, challenging common assumptions about screen use. Researchers say the key may be balancing physical activity with screen activities that encourage learning, creativity, and active thinking.
A little-known protein may be fueling Alzheimer’s — and scientists found a way to block it
An experimental Alzheimer’s compound prevented damaging protein clumps from forming in the brains of mice, helping nerve cells survive longer and reducing amyloid buildup. The treatment also appeared to improve heart health and slow some signs of aging, raising hopes for an entirely new way to combat dementia.
This 10-cent heart drug cuts hospitalizations by 25%
A centuries-old heart drug costing less than ten cents a day could help keep heart-failure patients out of the hospital. New research suggests low-dose digoxin can reduce heart-failure hospitalizations by about 25%, potentially paving the way for its return as a major treatment.
A little movement in midlife could pay off for your brain years later
Exercise and healthy blood sugar levels in midlife may help slow cognitive decline decades later. Physical activity appeared especially beneficial for Mexican American adults, suggesting that some brain-protective factors may differ across populations.
The common mistake that could make aging joints hurt more
Aging gradually wears down the cartilage and fluid that protect our joints, but avoiding movement may actually make matters worse. Exercise helps nourish cartilage, strengthens the muscles that protect joints, and can reduce osteoarthritis pain. Low-impact activities such as swimming, cycling, tai chi, yoga, and walking on varied terrain may also improve balance and mobility. Even a few minutes of the right kind of movement can make a difference.
Aging's Competing Paradigms: Another Decade of Investigation into Damage-Driven versus Programmed Theories
The nature of aging remains debated: is it the accumulation of damage or by execution of a program? Here, we revisit this long-standing dichotomy in light of recent experimental advances, each one of us supporting one of those paradigms and being critical about the other. The damage-driven model views aging as the progressive loss of function caused by imperfect repair and modulated by factors such as rate of damage accumulation, damage resistance, biological redundancy, and tissue regeneration....
