Thebacteria that cause tuberculosis (TB) also infect macrophages, the very immune cells meant to capture and destroy them. Once inside, the bacteria create a niche where they can persist for months or even years, tolerating even powerful antibiotics. This resilience is a major reason TB treatment requires long, intensive drug regimens lasting six to nine…

A sample of thorium. | Photo Credit: Alchemist-hp Atomic clocks keep time by counting the ‘ticks’ of electrons moving between two energy levels. Physicists have long wanted to count a nuclear tick instead. A nucleus is more shielded than an atom’s outer electrons, so its energy levels are expected to be less sensitive to disturbances….

Blame neurogenic inflammation. | Photo Credit: Jack Newing/Unsplash When we eat spicy food containing chillies, a substance in them called capsaicin binds to receptors on the nerve endings in our mouth and nose. These receptors work like sensors. When a specific molecule attaches to them, they send a signal that triggers a response. Capsaicin attaches…
