Researchers build circuit that harnessed the atomic motion of graphene to generate an electrical current that could lead to a chip to replace batteries.

A team of University of Arkansas physicists has successfully developed a circuit capable of capturing graphene’s thermal motion and converting it into an electrical current.

“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 Paul Thibado, professor of physics and lead researcher in the discovery.

Researchers have identified a bio-chemical circuit that supports neuron-microglia communication. When neurons are active, they release ATP. Microglia sense extracellular ATP and the compound draws the immune cell toward the neuron.circuit that supports neuron-microglia communication. When neurons are active, they release ATP.

The first Super Heavy prototype has entered assembly operations, with the forward barrel sleeved and the fuel stack section spotted. The LR1600/2 crane (aka Tankzilla) continued to grow, and Orbital Launch Pad construction continued with more concrete being pumped into the legs. Starships SN5 and 6 remain outside after having been moved out of the High Bay yesterday, and work continued around the site.

Scientists have created a device which could make it easier to harness super-fast quantum computers for real-world applications, a team at Finland’s Aalto University said on Wednesday.

Quantum computers are a new generation of machines powered by energy transfers between so-called “”— a fraction of a millimetre across.

Scientists believe the devices will eventually be able to vastly outperform even the world’s most powerful conventional supercomputers.

ESA’s new exoplanet mission, Cheops, has found a nearby planetary system to contain one of the hottest and most extreme extra-solar planets known to date: WASP-189 b. The finding, the very first from the mission, demonstrates Cheops’ unique ability to shed light on the Universe around us by revealing the secrets of these alien worlds.

Launched in December 2019, Cheops (the Characterising Exoplanet Satellite) is designed to observe nearby stars known to host planets. By ultra-precisely measuring changes in the levels of light coming from these systems as the planets orbit their stars, Cheops can initially characterize these planets — and, in turn, increase our understanding of how they form and evolve.

The new finding concerns a so-called ‘ultra-hot Jupiter ’ named WASP-189 b. Hot Jupiters, as the name suggests, are giant gas planets a bit like Jupiter in our own Solar System; however, they orbit far, far closer to their host star, and so are heated to extreme temperatures.
