Why can a phone call make you talk louder?

On a call, you hear the other person through a device while hearing your own voice through a mixture of air, your body, and sometimes electronic feedback. Change that feedback or add background noise, and your speaking level may change too. Experiments on vocal intensity help separate those effects from the simple assumption that distant listeners need louder speech.

Questions you could explore

  • What would happen if your own voice sounded quieter to you while the listener’s voice stayed the same?
  • How could background noise and hearing your own voice affect speaking volume in different ways?

Daylight and the body's clock

Even in a room with no clocks, your body follows an internal roughly 24-hour schedule of sleepiness, hunger, and alertness. Those internal daily rhythms respond to outside cues, with morning and evening light helping reset and coordinate the body's master clock.

How vaccines build immune memory

The first time the immune system encounters an unfamiliar antigen, building a response takes time. Vaccines help develop recognition and memory before a later encounter with a pathogen. Different types introduce antigens or instructions for making them in different ways, offering a starting point for exploring how immune memory works.

Antibiotics and the viruses they cannot treat

Antibiotics can treat certain bacterial infections, but they do not treat the viruses that cause a common cold. Because bacteria are living cells with their own metabolic machinery and viruses are tiny genetic packages that hijack your cells, an antibiotic that disables bacteria has no matching target in the viruses that cause a cold.
