Reheating brewed coffee several times shifts its chemistry, increasing bitterness and acidity as chlorogenic acids break down. For many, a single reheat is fine, but daily multiple reheats can aggravate reflux or dyspepsia. To keep your gut happier: drink fresh, avoid reheating more than once, use a tumbler to minimize heat cycling, and consider milder roasts or cold brew.
Scientists have discovered that cancer cells create an "acid wall" to evade the immune system, as revealed in a study published in Nature Biomedical Engineering. The acidic environment around tumors, caused by the cells' production of lactic acid, was found to be polarized, with increased acidity on one side compared to the other. This acidity forms a protective barrier against the immune system, preventing the infiltration of killer T cells. The findings open new possibilities for targeted cancer treatments and the development of drugs to prevent cancer cells from creating acid walls, making them more vulnerable to immune system attacks.
