The devices have a camera and multiple microphones to catch the wide range of sounds. Since dolphins have a variety of squeaks and clicks they seem to have a “secret language” and the team wants to try and decipher it.
Scientists at Nagoya University have identified neurons that fine-tune mammals’ body temperatures and keep them at 37°C. Exposing rats to hot temperatures activated EP3 neurons that tried to keep the animals’ temperatures consistent. This information could be used to artificially modify body temperature, helping people keep cool in hot environments for example.
The random movements that babies make in the womb may not be so random, found scientists from the University of Tokyo. The movements are thought to help the baby learn to control its body. The babies’ spontaneous movements can help coordination by performing a variety of movements rather than repetitive actions.
