The first electric plane took flight in 1973. There was just one person on board and the plane only stayed in the air for 14 minutes, but it was the beginning of an ongoing effort to power aircraft with batteries instead of fuel. Multiple companies are working on building faster, lighter, more efficient electric planes, as well as batteries to power those planes—and last week an aircraft made by Rolls-Royce hit some new milestones in the industry.

Cheerily dubbed the Spirit of Innovation, the plane is part of the company’s Accelerating the Electrification of Flight initiative. The seemingly precocious plane just completed its maiden flight a little over a month ago, and Rolls-Royce subsequently launched “an intense flight testing phase” to collect data on the performance of the aircraft’s power and propulsion system, a 400kW electric powertrain they call “the most power-dense propulsion battery pack ever assembled in aerospace.”

Last week, the company said in a press release, they set three new world records. First, the aircraft reached a top speed of 345.4 mph (555.9 km/h) over 1.8 miles (3 kilometers). That’s 132 mph (213 k/h) faster than the existing record. The Spirit of Innovation got up to an altitude of 9,842.5 feet (3,000 meters) in 202 seconds—60 seconds faster than the existing record. And finally, the plane reached a maximum speed of 387.4 mph (623 km/h) during its flight tests, which Rolls-Royce says makes it the world’s fastest all-electric vehicle. The company is waiting on the Federal Aviation Institute to confirm and certify these claims.

Chinese Scientists have previously showed their ability to change and control the weather inside China, but now there’s proof that they may actually modify and control the weather all over the world which has disastrous results in the form of Natural DIsasters such as Tornadoes. This video explores the possiblity of China having done this knowingly and what good could possibly come from having the ability to change the climate at your will. One thing is for sure, the science and technology behind these abilities is truly breathtaking.

Southwest Research Institute worked with government and commercial collaborators to successfully develop and demonstrate full-scale turbomachinery for one of the world’s first supercritical carbon dioxide (sCO2) power systems for a concentrated solar power (CSP) plant. The technology combines sCO2 power cycles with integrated thermal energy storage.

The project was supported by the U.S. Department of Energy’s APOLLO program, which was created to improve performance and reduced the cost of electricity from CSP plants. The 10MW sCO2 turbomachinery has successfully completed performance and endurance tests in a closed-loop environment.

SCO2 is carbon dioxide held above a critical temperature and pressure, which causes it to act like a gas while having the density of a liquid. It’s also nontoxic and nonflammable, having been used in dry cleaning processes, low-GHG refrigeration systems, as well as to decaffeinate coffee.

A new discovery could help scientists to understand “strange metals,” a class of materials that are related to high-temperature superconductors and share fundamental quantum attributes with black holes.

Scientists understand quite well how temperature affects electrical conductance in most everyday metals like copper or silver. But in recent years, researchers have turned their attention to a class of materials that do not seem to follow the traditional electrical rules. Understanding these so-called “strange metals” could provide fundamental insights into the quantum world, and potentially help scientists understand strange phenomena like high-temperature superconductivity.

Now, a research team co-led by a Brown University physicist has added a new discovery to the strange metal mix. In research published in the journal Nature, the team found strange metal behavior in a material in which electrical charge is carried not by electrons, but by more “wave-like” entities called Cooper pairs.

All memory storage devices, from your brain to the RAM in your computer, store information by changing their physical qualities. Over 130 years ago, pioneering neuroscientist Santiago Ramón y Cajal first suggested that the brain stores information by rearranging the connections, or synapses, between neurons.

Since then, neuroscientists have attempted to understand the physical changes associated with memory formation. But visualizing and mapping synapses is challenging to do. For one, synapses are very small and tightly packed together. They’re roughly 10 billion times smaller than the smallest object a standard clinical MRI can visualize. Furthermore, there are approximately 1 billion synapses in the mouse brains researchers often use to study brain function, and they’re all the same opaque to translucent color as the tissue surrounding them.

Study reveals why some attempts to convert the greenhouse gas into fuel have failed, and offers possible solutions.

If researchers could find a way to chemically convert carbon dioxide into fuels or other products, they might make a major dent in greenhouse gas emissions. But many such processes that have seemed promising in the lab haven’t performed as expected in scaled-up formats that would be suitable for use with a power plant or other emissions sources.

Now, researchers at MIT.

Cloud computing and blockchain industries may very well have one property in common; both are growing rapidly while having the potential to revolutionize their respective fields. However, up until now, pioneers within the two industries have not yet found a common interest. That could soon change as projects have started embracing the idea of integrating the blockchain into the cloud computing sector, and we could soon see a future of endless possibilities.

The game-changing development could mean big things for both industries. The development of the cloud computing sector has been aided by several elements, including the increasing use of mobile devices and data storage and processing capability. However, the integration of blockchain technology into the cloud computing industry could turn out to be one of the most significant drivers of the age of cloud computing.

Space Exploration Technologies Corporation’s (SpaceX) ch8ef executive officer Mr. Elon Musk has shared the latest details for his company’s Starlink satellite internet constellation. Starlink is SpaceX’s internet service which uses low Earth orbit (LEO) small satellites to beam down the Internet to its users. Due to a rapid cadence of launches, SpaceX has ensured that Starlink is the world’s largest internet constellation in service, and the company is currently upgrading the satellites with laser based connectivity. This will allow Starlink to expand its coverage and reach areas that cannot be served without ground stations to connect the satellites and the users to internet servers.

Starlink Will Soon Start To Operate Laser Links Between Satellites Confirms Musk

Mr. Musk shared the latest details through his social media platform Twitter, as he outlined the number of Starlink satellites currently in orbit and his company’s plans to activate newer spacecraft capable of optical communication. These are crucial for evaluating the internet service’s current capacity, which has come under fire from rivals in proceedings for spectrum sharing and licensing currently underway at the Federal Communications Commission (FCC).
