Using a single memory atom in a cavity, a deterministic protocol is implemented to efficiently grow Greenberger–Horne–Zeilinger and linear cluster states by means of single-photon emissions.
Researchers from North Carolina State University used computational analysis to predict how optical properties of semiconductor material zinc selenide (ZnSe) change when doped with halogen elements, and found the predictions were confirmed by experimental results. Their method could speed the process of identifying and creating materials useful in quantum applications.
Creating semiconductors with desirable properties means taking advantage of point defects—sites within a material where an atom may be missing, or where there are impurities. By manipulating these sites in the material, often by adding different elements (a process referred to as “doping”), designers can elicit different properties.
“Defects are unavoidable, even in ‘pure’ materials,” says Doug Irving, University Faculty Scholar and professor of materials science and engineering at NC State. “We want to interface with those spaces via doping to change certain properties of a material. But figuring out which elements to use in doping is time and labor intensive. If we could use a computer model to predict these outcomes it would allow material engineers to focus on elements with the best potential.”
James Webb Space Telescope’s first exoplanet image could tell us a lot about our own Solar System.
NASA just released the James Webb Space Telescope’s first infrared images of an exoplanet, and it could shed light on how solar systems evolve.
The trial was only on 8 people, but it appears to have worked well across the board.
Published in GeroScience, a groundbreaking study from the renowned Conboy lab has confirmed that plasma dilution leads to systemic rejuvenation against multiple proteomic aspects of aging in human beings.
This paper takes the view that much of aging is driven by systemic molecular excess. Signaling molecules, antibodies, and toxins, which gradually accumulate out of control, cause cells to exhibit the gene expression that characterizes older cells.
While the bloodstreams of old and young mice have been joined in previous experiments with substantial effects [1], this heterochronic parabiosis approach is neither feasible nor necessary for human beings. Instead, this paper focuses on therapeutic plasma exchange (TPE), a procedure that simply replaces blood plasma with saline solution and albumin. This procedure has already been used to dilute pathogenic, toxic compounds [2], the systemic problems associated with autoimmune and neurological disorders, including Alzheimer’s [3], and even the lingering aftereffects of viral infection [4].
The aircraft is one of Northrop Grumman’s best models.
The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning aircraft. Its latest and most advanced version is the E-2D Advanced Hawkeye.
which features the AN/APY-9 radar (capable of detecting fighter-sized stealth aircraft), radio suite, mission computer, integrated satellite communications, flight management system, improved T56-A-427A engines, a glass cockpit and aerial refueling.
“It’s historic,” says MIT scientists.
In a significant breakthrough, the Massachusetts Institute of Technology’s (MIT) lunchbox-sized machine has been producing oxygen from the Red Planet’s atmosphere for more than a year, giving hope of life on Mars one day.
Since April 2021, the MIT-led Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) successfully made oxygen from the Red Planet’s carbon-dioxide-rich atmosphere, according to a press release published by the institute on Wednesday.
“It’s historic,” said MOXIE’s deputy principal investigator Jeffrey Hoffman, a professor of the practice in MIT’s Department of Aeronautics and Astronautics.
The Large Hadron Collider
Posted in computing, particle physics
To smash atoms with unimaginable power.
Cern’s Large Hadron Collider (LHC) is back online after a three-year technical shutdown period. The expert scientists at the famous research facility ran the powerful accelerator at the end of April, and Run 3 physics started in early July. The entire process ran at the highest energy level ever achieved in an accelerator.
The LHC experiments are expected to collect so much data on nature at its smallest levels that it is measured in petabytes.
(LHC) is the world’s largest and most powerful particle accelerator. It consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way.
The contract will run through 2030 and makes SpaceX over $4.9 billion in total.
You haven’t seen the tail end of SpaceX launches to the International Space Station (ISS) quite yet. NASA awarded the Elon Musk-founded company a $1.4 billion contract to send five more astronaut missions to the ISS, per NASA’s press release.
The contract, part of the agency’s Commercial Crew Transportation Capability (CCtCap), runs through 2030 and brings the total value of the signed agreement with SpaceX to over $4.9 billion.
NASA has awarded five additional missions to Space Exploration Technologies Corporation (SpaceX) of Hawthorne, California, for crew transportation services to the International Space Station as part of the agency’s Commercial Crew Transportation Capability (CCtCap) contract.
When you hit the jackpot-or don’t.
Imagine receiving $10.5 million while expecting a $100 refund to be transferred to your bank account and no one, except you, recognizes it until seven months have passed. That’s recently what happened in Melbourne, Australia when a cryptocurrency company bestowed a fortune to a woman, initially reported by 7NEWS. Back in May 2021, Crypto.com, one of the world’s largest cryptocurrency trading platforms, transferred the amount to Thevamanogari Manivel. Upon receiving the money, Manivel and her sister Thilagavathy Gangadory started spending it like greased lightning.
It took the company seven months to realise its mistake. By the time they did, millions had already been spent.
It can generate 1.3 gigawatts of clean energy.
Hornsea 2, the world’s largest offshore wind farm located in the North Sea, has gone fully operational, a press release from its builder, Orsted, said. In its bid to achieve net zero carbon emissions by 2050, the U.K. is banking heavily on wind-generated power. To this effect, it commissioned the Hornsea One project, which was the largest offshore wind farm in the world at the time of achieving fully operational status in 2020. Two years later, the Hornsea 2 project is fully operational and has claimed the bragging rights for being the largest offshore wind farm in the world.
The Hornsea zone, an area of the North Sea covering more than 2,000 km2, is also set to include Hornsea 3. The 2.8 GW project is planned to follow Hornsea 2 having been awarded a contract for difference from the UK government earlier this year.
Hornsea 2 has played a key role in the ongoing development of a larger and sustainably competitive UK supply chain to support the next phase of the UK’s offshore wind success story. In the past five years alone, Ørsted has placed major contracts with nearly 200 UK suppliers. Ørsted has invested GBP 4.5 billion in the UK supply chain to date and expects to make another GBP 8.6 billion of UK supply chain investments over the next decade.
Ørsted now has 13 operational offshore wind farms in the UK, providing 6.2GW of renewable electricity for the UK – enough to power more than 7 million homes. Hornsea 2 makes a significant contribution to Ørsted’s global ambition of installing 30 GW offshore wind by 2030. Ørsted currently has approx. 8.9 GW offshore wind in operation, approx. 2.2 GW under construction, and another approx. 11 GW of awarded capacity under development including Hornsea 3.
