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.

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.”

Lubin received funding from NASA last year to study the possibility of using photonic laser thrust, a technology that does exist, as a new system to propel spacecraft to relativistic speeds, allowing them to travel farther than ever before. The project is called DEEP IN, or Directed Propulsion for Interstellar Exploration, and the technology could send a 100-kg (220-pound) probe to Mars in just three days, if research models are correct. A much heavier, crewed spacecraft could reach the red planet in a month—about a fifth of the time predicted for the SLS.

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.

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 could now separate these entangled dice. You could have your friend Alice take one of these to Macau, while the other one stays with you in Las Vegas. And as soon as you rolled your dice, the other one would always instantly show a number that added up to 7.

Since this happens instantly, did your dice communicate at faster than speed of light to Macau?

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.

Can you imagine a brain and its workings being replicated on a computer? That is what the EBRAINS Cellular Level Simulation Platform aims to do. The Platform is available to researchers worldwide, so that they can compare their experimental results with model predictions and conduct investigations that are not possible experimentally.

Simulation also aims to replicate work on animal models, such as the mouse. In addition, the computing environment used for simulation offers the possibility of studying disease processes electronically.

However, the challenge is a complex one, as the human brain contains 86 billion brain cells (known as neurons) each with an average of 7,000 connections to other neurons (known as synapses). Current computer power is insufficient to model a entire human brain at this level of interconnectedness.
