Permanent liquid magnets have now been created in the lab

Posted by in categories: biotech/medical, nanotechnology, robotics/AI

The rules about what makes a good magnet may not be as rigid as scientists thought. Using a mixture containing magnetic nanoparticles, researchers have now created liquid droplets that behave like tiny bar magnets.

Magnets that generate persistent magnetic fields typically are composed of solids like iron, where the magnetic poles of densely packed atoms are all locked in the same direction (SN: 2/17/18, p. 18). While some liquids containing magnetic particles can become magnetized when placed in a magnetic field, the magnetic orientations of those free-floating particles tend to get jumbled when the field goes away — causing the liquid to lose its magnetism.

Scientists Print Magnetic Liquid Droplets

Posted by in categories: bioengineering, biotech/medical, robotics/AI

Scientists at Berkeley Lab have made a new material that is both liquid and magnetic, opening the door to a new area of science in magnetic soft matter. Their findings could lead to a revolutionary class of printable liquid devices for a variety of applications from artificial cells that deliver targeted cancer therapies to flexible liquid robots that can change their shape to adapt to their surroundings.

NASA’s Voyager twins refuse to die

Posted by in categories: robotics/AI, space travel

It’s been almost 42 years since NASA sent its two Voyager spacecraft on record-breaking missions, and both of the decades-old robots are still alive. Voyager 1 and 2 are 13.5 billion and 11.1 billion miles from Earth, respectively, and it’s up to NASA engineers to ensure they remain up and running for as long as possible.

As the agency reveals in a new update, mission managers recently decided to shut down one of the heaters on Voyager 2 which is designed to keep its cosmic ray subsystem (CRS) instrument at a comfortable temperature. This was done to conserve energy, but the CRS itself miraculously still works, despite dipping well below the temperatures it was tested at over four decades ago.

Tiny vibration-powered robots the size of the world’s smallest ant

Posted by in categories: 3D printing, biotech/medical, robotics/AI

Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these “micro-bristle-bots” might work together to sense environmental changes, move materials—or perhaps one day repair injuries inside the human body.

The respond to different frequencies depending on their configurations, allowing researchers to control individual bots by adjusting the vibration. Approximately two millimeters long—about the size of the world’s smallest ant—the bots can cover four times their own length in a second despite the physical limitations of their small size.
