Scientists have uncovered a sweet twist in the body’s fight against cancer. Glucose, best known as the fuel that powers our cells, also helps immune cells called T cells communicate and organize their attack on tumors. By turning sugar into special building blocks, T cells strengthen their internal signals and become far more effective cancer killers. Read more

Every year, Panama’s Pacific coast benefits from powerful seasonal winds that drive nutrient-rich waters to the surface, sustaining fisheries and protecting coral reefs. But in 2025, for the first time in at least four decades, this crucial upwelling did not occur. Scientists suspect weakened trade winds linked to climate disruption played a role, leaving cooler waters absent and fisheries under stress. Read more

Scientists from Finland and the UK have uncovered groundbreaking evidence that heart attacks may be triggered by infectious processes rather than just cholesterol and lifestyle factors. Hidden bacterial biofilms inside arterial plaques can remain dormant for decades, shielded from the immune system, until activated by a viral infection or another external trigger. Once awakened, the bacteria spark inflammation, rupture arterial plaques, and cause blockages that lead to heart attacks. Read more
