The discovery adds credence to the idea that Earth got its water from comets – especially as the disc seems to contain enough water to fill Earth’s oceans thousands of times over. Hot water vapour has previously been detected in the inner part of the planet-forming discs of nascent, alien solar systems. But this is […]

The system, called IndiGo, consists of a low-cost flexible plastic 2.5W solar panel that charges a battery. This is connected […]
Habits may be difficult to change, but now at least we have an insight into how they form. When a group of neurons fire simultaneously, the activity appears as a brainwave. Different brainwave-frequencies are linked to different tasks in the brain. To track how brainwaves change during learning, Ann Graybiel and Mark Howe at the […]
