Samsung unveils “Ballie” SPY MACHINE that rolls around your home spying on everything while controlling your electronic devices
In a race with Amazon to the bottom, Samsung has unveiled a new spy machine robot called “Ballie” that rolls around people’s homes watching and listening to everything they do while controlling all their electronic devices. First unveiled back in 2020, Ballie’s latest hypothetical design is roughly the size of a bowling ball on wheels […]

Scientists build circuit that generates clean, limitless power from graphene
Physicists from the University of Arkansas (UArk) have successfully developed a circuit capable of generating electricity from the natural thermal motion of graphene. “An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors,” said lead researchers Paul Thibado, a professor of physics and lead […]

“Wearable microgrid” uses energy from the human body to power small gadgets
Engineers at the University of California, San Diego (UC San Diego) have developed a “wearable microgrid” that’s able to utilize energy from the human body to power small electronic devices. In a paper published on March 9 in the journal Nature Communications, the researchers said that they drew inspiration from community microgrids. “We’re applying the concept of […]

New catalyst material can help spur the rise of lithium-sulfur batteries
Lithium-sulfur batteries (LSBs) are some of the most promising batteries available today. They are cheaper, lighter and capable of storing much more energy than conventional lithium-ion batteries (LIBs), which currently power most kinds of electronic devices. But LSBs can only be recharged a few times before degrading. Now, South Korean researchers might have just found the right catalyst […]

“Important theoretical finding” shows how breaks in temporal symmetry result in molecules that can encode data from Weyl semimetals
A study published in Scientific Reports shows that breaks in temporal symmetry can produce molecules in materials called Weyl semimetals that can encode data. Researchers from Brazil and Iceland said that the theoretical finding can contribute to the development of quantum computing and spintronics – an emerging technology that uses electron spin instead of electron charge for faster, more efficient […]

Physicists build “energy harvesting” circuit from graphene
A team of physicists from the University of Arkansas (U of A) has successfully developed graphene-based circuits capable of providing nearly limitless power for small devices. Described in a paper published in the journal Physical Review E, the findings prove a theory the physicists developed at the U of A three yeas ago. This theory stated that freestanding graphene […]

Reusing carbon dioxide: Scientists capture and convert it into useful molecules
Researchers at Michigan Technological University have developed a novel device that captures carbon dioxide (CO?) and converts it into useful products. The device, which the team presented at the Society of Mining, Metallurgy and Exploration’s annual meeting in Denver, works just like a carbon scrubber to remove CO? from flue gas emitted from power plants. But unlike other scrubbers, which industries are […]

College students now tracked like cattle, using new technology that monitors their every move across campus, 24 hours a day
If you’ve ever visited, worked at, or merely observed a cattle ranch, you probably noticed that the animals had colored tags in their ears that identified their owners and helped to keep tabs on their whereabouts. Well, the same thing is now happening at colleges and universities all across the country as many institutions of […]

Tough new high-tech fiber developed by engineers could be used as skin for robots
It’s not just jobs that robots are taking over from humans; they could soon look like one, too. Researchers from North Carolina State University have developed a tough high-tech fiber with the toughness and elasticity of human skin. It can be incorporated into soft robotics, packaging materials or next-generation textiles. The researchers made fibers using a gallium metal core surrounded by […]

Scientists discover “electric” bacteria – can it lead to next-gen batteries and miniature pacemakers?
Experts know that a strange species of bacteria found in oxygen-deprived sediment and soil can generate electricity. But they only recently learned that the microorganism achieves this through a method that differs from that used by other electric bacteria. Called Geobacter sulfurreducens, the anaerobic bacteria possess a unique biological structure. This previously unidentified feature makes it possible […]
