Only the T cells best adapted to the "enemy" undergo the second activation phase First trained, then selectively activated: The "killer cells" of our immune system are prepared for action in two phases instead of just one, as researchers have discovered. In the first phase, the T cells learn the characteristics of the pathogens they are to destroy. In the second, newly discovered phase, however, only the T cells that best recognize the pathogens are activated and dispatched,

A one-minute 100-hertz tone reduces dizziness and nausea caused by seasickness, driving, or flying Sound as medicine: A new type of sound stimulation could help combat motion sickness and seasickness. When our ears are exposed to a loud, pure tone of 100 hertz, it helps our vestibular system, as experiments with test subjects have shown. The approximately one-minute tone triggers vibrations in the inner ear and counteracts the disruptive effects of the rocking ship, the fligh

Demis Hassabis and John Jumper, the 2024 Nobel Prize laureates in chemistry, have developed an AI model to solve a 50-year-old problem: predicting proteins’ complex structures.In 2020, Hassabis and Jumper presented an AI model called AlphaFold2. With its help, they have been able to predict the structure of virtually all the 200 million proteins that researchers have identified. Since their breakthrough, AlphaFold2 has been used by more than two million people from 190 count
