Circadian rhythm, the body’s internal clock, may affect a person’s risk of dementia. People with weaker or more irregular body clocks had a higher risk of developing dementia. Being most active later in the day, instead of earlier, was linked to a 45% increased risk of dementia.

Injectable nanoparticles reprogram immune cells within tumors to attack cancer: New therapy directly converts macrophages inside tumors into anti-cancer cell therapies. In mouse models with melanoma, tumor growth was markedly suppressed, and therapeutic effect extended to a systemic immune response.

Research shows that a single binge-drinking episode—about four drinks for women or five for men in two hours—can weaken the gut in measurable ways. Even in healthy adults, alcohol makes the intestinal lining more permeable, allowing bacteria and toxins to enter the bloodstream.
