“Electron family” state of matter hints at new type of superconductivity

Posted by in categories: particle physics, quantum physics

Superconductivity occurs when electrons in a metal pair up and move through the material without resistance. But there may be more to the story than we thought, as scientists in Germany have now discovered that electrons can also group together into families of four, creating a new state of matter and, potentially, a new type of superconductivity.

Conductivity is a measure of how easily electrons (and therefore electricity) can move through a material. But even in materials that make good conductors, like gold, electrons will still encounter some resistance. Superconductors, however, remove all such barriers and provide zero resistance at ultracold temperatures.

The reason electrons can move through superconductors so easily is because they pair up through a quantum effect known as Cooper pairing. In doing so, they raise the minimum amount of energy it takes to interfere with the electrons – and if the material is cold enough, its atoms won’t have enough thermal energy to disturb these Cooper pairs, allowing the electrons to flow freely with no loss of energy.

The thinnest CD-RW: Atomic-scale data storage possible

Posted by in categories: computing, encryption, nanotechnology

Using a focused laser beam, scientists can manipulate properties of nanomaterials, thus ‘writing’ information onto monolayer materials. By this means, the thinnest light disk at atomic level was demonstrated.

The bottleneck in atomic-scale area may be broken by a simple technique, thanks to recent innovative studies conducted by scientists from Nanjing Normal University (NJNU) and Southeast University (SEU).

Through a simple, efficient and low-cost technique involving the focused laser and ozone treatment, the NJNU and SEU research teams, leading by Prof. Hongwei Liu, Prof. Junpeng Lu and Prof. Zhenhua Ni demonstrated that the photoluminescence (PL) emission of WS2 monolayers can be controlled and modified, and consequently, it works as the thinnest light disk with rewritable data storage and encryption capability.

The Femtojoule Promise of Analog AI

Posted by in categories: mathematics, robotics/AI, space

Want AI that can do 10 trillion operations using just one watt? Do the math using analog circuits instead of digital.


There’s no argument in the astronomical community—rocket-propelled spacecraft can take us only so far. The SLS will likely take us to Mars, and future rockets might be able to help us reach even more distant points in the solar system. But Voyager 1 only just left the solar system, and it was launched in 1977. The problem is clear: we cannot reach other stars with rocket fuel. We need something new.

“We will never reach even the nearest stars with our current propulsion technology in even 10 millennium,” writes Physics Professor Philip Lubin of the University of California Santa Barbara in a research paper titled A Roadmap to Interstellar Flight. “We have to radically rethink our strategy or give up our dreams of reaching the stars, or wait for technology that does not exist.”

Rolls-Royce Claims Its All-Electric Plane Is World’s Fastest

Posted by in categories: government, sustainability, transportation

In a recent news release 0, the company, not to be mistaken for the car company owned by BMW, claimed that the Spirit of Innovation set three new world records earlier this week. On flight tests carried out on Nov. 16, Rolls-Royce said its aircraft reached a top speed of 345.4 mph (555.9 km/h) over 1.8 miles (3 kilometers), exceeding the current record by 132 mph (213 k/h). It broke another record in a subsequent 9.3-mile (15 kilometer) flight, during which it reached 330 mph (532.1 km/h), surpassing the current record by 182 mph (292.8 km/h).

The Spirit of Innovation didn’t stop there, though. Rolls-Royce affirms that it smashed another record when it reached 9,842.5 feet (3,000 meters) in 202 seconds, beating the current record by 60 seconds. In the company’s view, it also took the title of the world’s fastest all-electric vehicle when it reached a maximum speed of 387.4 mph (623 km/h) during its flight tests.

The company’s aircraft is powered by a 400kW electric powertrain and “the most power-dense propulsion battery pack ever assembled in aerospace.” It’s part of the Accelerating the Electrification of Flight project 0, which receives half of its funding from the UK government and the Aerospace Technology Institute.

Entanglement Theory may Reveal a Reality we can’t Handle

Posted by in categories: particle physics, quantum physics

What is entanglement theory? It is a Mystery, and here is a potential solution. But its implications are so paradigm shattering that most scientists refuse to believe it. Maybe we can’t handle the truth?

Imagine you found a pair of dice such that no matter how you tossed them, they always added up to 7. Besides becoming the richest man in Vegas, what you would have there is something called an entangled pair of dice.

You don’t have free will, but don’t worry

Posted by in categories: ethics, neuroscience, quantum physics

In this video I explain why free will is incompatible with the currently known laws of nature and why the idea makes no sense anyway. However, you don’t need free will to act responsibly and to live a happy life, and I will tell you why.

Why are we conscious? The answer lies in other animals’ heads

Posted by in category: neuroscience

It’s easy to think human conscious experience is unique, but a better understanding of consciousness’s mysteries comes by tracing it back in the evolutionary tree.
