“Acoustic holograms” quickly assemble objects from particles or cells

Posted on by

Scientists have created “acoustic holograms” that can assemble matter into 3D objects, using just sound. The technique works with various types of particles and even living cells, allowing for a new kind of 3D printing that’s fast and contact-free.Cont… Continue reading “Acoustic holograms” quickly assemble objects from particles or cells→

Consumer drone adapted to help predict volcanic eruptions

Posted on by

The analysis of volcanic gases allows scientists to determine what processes are taking place deep within volcanoes, including the possibility of impending eruptions. And while big, expensive drones have previously been used to sample those gases, a sm… Continue reading Consumer drone adapted to help predict volcanic eruptions→
