Scientists create a robot made entirely of living cells

September 8th, 2020 at 11:29 am » Comments Off

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. […]

Army of a million microscopic robots created to explore on tiny scale

September 1st, 2020 at 10:07 am » Comments Off

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 […]

Atom-by-atom assembly makes for cheap, tuneable graphene nanoribbons

July 10th, 2020 at 3:54 am » Comments Off

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 […]

New graphene battery recharges blazingly fast, and it’s already on the market

January 19th, 2020 at 8:54 pm » Comments Off

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 […]

Researchers demonstrate chip-to-chip quantum teleportation

December 29th, 2019 at 12:09 am » Comments Off

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. […]

A nanotube material conducts heat in just one direction

December 21st, 2019 at 2:49 am » Comments Off

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, […]

The world’s most advanced nanotube computer may keep Moore’s Law alive

September 6th, 2019 at 11:32 am » Comments Off

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 […]

Scientists forge ahead with electron microscopy to build quantum materials atom by atom

October 19th, 2018 at 9:37 am » Comments Off

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.

Genetically engineered bacteria paint microscopic masterpieces

September 3rd, 2018 at 10:11 am » Comments Off

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 […]

German researchers have built a quantum transistor using just a single atom

August 22nd, 2018 at 10:09 am » Comments Off

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 […]

Graphene-based armor could stop bullets by becoming harder than diamonds

December 24th, 2017 at 9:18 am » Comments Off

Made of two stacked layers of graphene, diamene temporarily becomes harder than bulk diamonds under impact.

Strange atomic ripples in graphene could unlock clean, limitless energy

December 12th, 2017 at 10:40 am » Comments Off

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.
