CONCLUSION: These findings identify oxidative stress and disrupted autophagy as key mediators of saturated-fat-induced neuronal decline and highlight a sex-specific vulnerability to dietary fat composition. This work establishes Drosophila as a powerful model for dissecting nutritional drivers of neural aging and suggests that metabolic stress pathways represent critical early targets in diet-associated neurodegeneration.

CONCLUSIONS: Personal EHR engagement among the vulnerable aging population is influenced by a complex interplay of patient, HCP, and technology-related factors, which must be addressed holistically to ensure inclusive usage and adherence to digital health tools.

A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones. By blocking these harmful protein packages before they reach new cells, researchers believe it may one day be possible to slow the disease's relentless progression.

Scientists at the University of Oxford have created a calculator that predicts a person's individual risk of serious muscle disorders from statin medications. Their analysis found that more than 98% of people who qualify for statins are at low risk for these rare complications, despite widespread concerns about side effects. The study also revealed that most eligible patients are not taking statins, potentially missing important protection against heart attacks and strokes.

Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain's energy supply. A new review examined five randomized clinical trials involving 238 participants and found mixed results. Two studies, both involving women with major depressive disorder, reported that adding creatine to standard treatment improved symptoms, while three others found no meaningful benefit.

White House asserts expanded authority to prosecute any wasteful spending “in the national interest”

A new stem-cell-inspired technique allows scientists to grow vast numbers of immune-cell progenitors that can be engineered to hunt cancer and strengthen immune responses. In animal studies, the cells fought tumors, restored immune function, and showed promise as a durable, off-the-shelf therapy platform.
