Comments Off on Acoustic tractor beams could allow humans to levitate in the near future

Researchers from the University of Bristol are taking us into the future with a new discovery that could pave the way for human levitation. The powerful new technology uses tractor beams of sound to levitate liquids or even large objects – like a human beings – in mid-air. It’s like something straight out of a science fiction movie. Up until now, acoustic tractor beams could only lift tiny objects – anything larger than the wavelength would become rapidly unstable. But this new technology utilizes acoustic vortices that shift rapidly to hold and move objects. It’s kind of like trapping an object in a powerful tornado of sound, with a silent eye and loud sound on the exterior. By quickly changing the rate of rotation, scientists can stabilize the tractor beam and even manipulate it to hold larger objects.

This was only thought to be possible using lower pitches making the experiment audible and dangerous for humans,” said Senior Research Associate Dr. Mihai Caleap. + Physical Review Letters Via Phys.org Images via Physical Review Letters

Yes, that’s a see-through mouse you are looking at. And yes, it’s pretty gross, but thankfully, no, it’s not alive . The transparent mouse represents a breakthrough for scientists at the California Institute of Technology who say that it will lead to a better understanding of the relationships between nervous systems and organs through “whole-organism mapping.” Despite the queasiness factor, the technique has the potential to aid research into a variety of health issues, including autism, chronic pain and the development of cancerous cells.

Comments Off on High-Powered Lasers Could Help Scientists Harness Sustainable Fusion Energy

A newly-published study describes how for the first time, scientists have been able to generate more energy through an experiment than was used to initiate nuclear fusion . For more than 50 years, researchers have struggled to harness the same physical process that fuels the sun, and use it to generate a powerful source of sustainable energy here on Earth. While only a small amount of material was used in this experiment and the technology is years away from commercial use, this announcement represents a major breakthrough in the field.
