Participants lost more weight on a low-fat vegan diet than on the Mediterranean diet, largely due to eliminating animal foods and reducing oils and nuts. Increased intake of plant foods, even “unhealthy” ones, was strongly associated with greater weight loss.

Scientists are uncovering what makes some carcinomas so resistant: their ability to change identity. Two new studies reveal crucial proteins and structures that could become targets for future therapies. These discoveries deepen understanding of how tumors reprogram themselves and point toward highly specific treatments. The work raises hopes for safer, more selective cancer drugs.

Hypertension begins harming the brain surprisingly early, even before measurable blood pressure increases. Key cells related to blood vessels, signaling, and myelin maintenance begin aging prematurely and malfunctioning. These disruptions resemble early patterns seen in cognitive decline and Alzheimer’s. Encouragingly, losartan reversed some of this early damage in mice.

A research team has found that specific immune cells can connect with muscle fibers in a lightning-fast, neuron-like way to promote healing. These cells deliver quick pulses of calcium, triggering repair within seconds. The mechanism works in both injury and disease models. The discovery could inspire new treatments for muscle recovery and degeneration.

A massive long-term study shows that Mediterranean and plant-based diets can help prevent chronic constipation in aging adults. Surprisingly, the benefits weren’t explained by fiber alone. Western and inflammatory diets raised constipation risk, while low-carb diets showed minimal impact. The research underscores how diet quality influences gut health well beyond traditional advice.
