A Xenobot, 650-750 microns in diameter. The “legs” help it shuffle around in the petri dish. ’Xenobots’ could be used to clean up microplastics or deliver medication in the body Scientists have unveiled the first ever “living robot,” an organism made up of living cells, which can move around, carry payloads, and even heal itself.

Artist’s rendition of an array of microscopic robots A troop of a million walking robots could enable scientific exploration at a microscopic level. Researchers have developed microscopic robots before, but they weren’t able to move by themselves, says Marc Miskin at the University of Pennsylvania. That is partly because of a lack of micrometre-scale actuators […]
Graphene nanoribbons could serve a variety of purposes, and a new way to produce then could help unleash this potential The wonder material graphene can take many forms for many different purposes, from transparent films that repel mosquitoes to crumpled balls that could boost the safety of batteries. One that has scientists particularly excited is […]
Faster charging, longer lasting, and lower temperatures. These are the three major benefits from a lithium battery that has been infused with wonder-material graphene. Thing is, we’ve all heard about the benefits of graphene before, but despite all the hype, we’ve yet to really see it used in devices and products that you can actually […]
Llewellyn et al realize an array of microring resonators (MRRs) to generate multiple high-quality single photons, which are monolithically integrated with linear-optic circuits that process multiple qubits with high fidelity and low noise. A research team led by University of Bristol scientists has successfully demonstrated quantum teleportation of information between two programmable micrometer-scale silicon chips. […]
Photograph of nanotubes being created Asymmetric conductors could revolutionize cooling systems for computers and other devices. Heat is something of a nuisance for electrical engineers. It reduces the reliability of electronic devices and even causes them to fail completely. That’s why computer components are liberally smeared with thermal paste and connected to heat pipes, fans, […]
Up close photograph of nanotube MIT researchers have found new ways to cure headaches in manufacturing carbon nanotube processors, which are faster and less power hungry than silicon chips. A team of academics at MIT has unveiled the world’s most advanced chip yet that’s made from carbon nanotubes—cylinders with walls the width of a single […]
With a STEM microscope, ORNL’s Ondrej Dyck brought two, three and four silicon atoms together to build clusters and make them rotate within a layer of graphene, a two-dimensional layer of carbon atoms that exhibits unprecedented strength and high electrical conductivity.

Scientists have used genetically engineered bacteria to recreate a masterpiece at a microscopic scale. By engineering E. coli bacteria to respond to light, they’ve guided the bacteria like tiny drones toward patterns that depict Leonardo da Vinci’s Mona Lisa. It’s not artistic recognition they’re after. Rather, the researchers want to show that these engineered organisms […]
A team of researchers at Germany’s Karlsruhe Institute of Technology have developed a quantum transistor using just a single atom, and capable of operating at room temperature. The device points toward major new frontiers in computing power and efficiency. Transistors, which control the flow of electronic signals, are the basis of modern electronics. The steady […]
Made of two stacked layers of graphene, diamene temporarily becomes harder than bulk diamonds under impact.
By all measures, graphene shouldn’t exist. The fact it does comes down to a neat loophole in physics that sees an impossible 2D sheet of atoms act like a solid 3D material.
