A fully electric flying car that’ll cost about $300,000 just won approval to start testing on the road – and in the air.
Alef Aeronautics, a Californian automaker, said in a press release it had received a Special Airworthiness Certification from the Federal Aviation Administration (FAA) for the Model A.
It’s the first such approval for a flight-capable car, according to the startup, which has been backed by the likes of SpaceX.
A system using photonics-based synthetic dimensions could be used to help explain complex natural phenomena.
Researchers at the University of Rochester have developed a chip-scale optical quantum simulation system using controlled photon.
A photon is a particle of light. It is the basic unit of light and other electromagnetic radiation, and is responsible for the electromagnetic force, one of the four fundamental forces of nature. Photons have no mass, but they do have energy and momentum. They travel at the speed of light in a vacuum, and can have different wavelengths, which correspond to different colors of light. Photons can also have different energies, which correspond to different frequencies of light.

A breathtaking scientific revolution is taking place – biotechnology has been progressing at stunning speed, giving us the tools to eventually gain control over biology. On the one hand solving the deadliest diseases while also creating viruses more dangerous than nuclear bombs, able to devastate humanity.

Computers are built around logic: performing mathematical operations using circuits. Logic is built around things such as Adders—not the snake; the basic circuit that adds together two numbers. This is as true of today’s microprocessors as all those going back to the very beginning of computing history. You could go back to an abacus and find that, at some fundamental level, it does the same thing as your shiny gaming PC. It’s just much, much less capable.
Nowadays, processors can do a lot of mathematical calculations using any number of complex circuits in a single clock. And a lot more than just add two numbers together, too. But to get to your shiny new gaming CPU, there has been a process of iterating on the classical computers that came before, going back centuries.

A team led by Academician Prof. Guangcan Guo from the Chinese Academy of Sciences (CAS) provides a comprehensive overview of the progress achieved in the field of quantum teleportation. The team, which includes Prof. Xiaomin Hu, Prof. Yu Guo, Prof. Biheng Liu, and Prof. Chuanfeng Li from the University of Science and Technology of China (USTC), CAS, was invited to publish a review paper on quantum teleportation in the peer-reviewed scientific journal Nature Review Physics. The paper was officially released online on May 24.
As one of the most important protocols in the field of quantum information, quantum teleportation has attracted great attention since it was proposed in 1993. Through entanglement distribution and Bell-state measurement, quantum teleportation enables the nonlocal transmission of an unknown quantum state, which has deepened the understanding of quantum entanglement. More importantly, quantum teleportation can effectively overcome the distance limitation of direct transmission of quantum states in quantum communication, as well as realize long-range interactions between different quantum bits in quantum computing.

Our ideas about the universe are based on a century-old simplification known as the cosmological principle. It suggests that when averaged on large scales, the Cosmos is homogeneous and matter is distributed evenly throughout.
This allows a mathematical description of space-time that simplifies the application of Einstein’s general theory of relativity to the universe as a whole.
Our cosmological models are based on this assumption. But as new telescopes, both on Earth and in space, deliver ever more precise images, and astronomers discover massive objects such as the giant arc of quasars, this foundation is increasingly challenged.

SpaceX has announced a plan to give T-Mobile customers direct access to the Starlink satellite constellation, ensuring they’ll have mobile coverage nearly everywhere in the US.
“I think this is really a massive game changer,” said SpaceX CEO Elon Musk during a live event at SpaceX’s Starbase facility in Texas. “In a nutshell, it’s no more dead zones.”
The challenge: Cell coverage is widespread in the US, but there are still more than half a million square miles — nearly twice the size of Texas — where you won’t find a signal from any carrier.
