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...

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. The main candidate for a nuclear clock is...

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 to receptors that normally react to actual heat....
