The World’s First Flying Car Approved in US: Here’s What It Looks Like

Posted by in category: transportation

In two years, the world’s first flying car will no longer be a science-fiction concept. The Federal Aviation Administration gave the Alef Aeronautics “Model A” car a Special Airworthiness Certification in June, approving the vehicle for road and air tests, the New York Post reported.

What Happens When Scientists Put a Human Intelligence Gene Into a Monkey?

Posted by in categories: biotech/medical, evolution, genetics, neuroscience

Scientists adding a human intelligence gene into monkeys — it’s the kind of thing you’d see in a movie like Rise of the Planet of the Apes. But Chinese researchers have done just that, improving the short-term memories of the monkeys in a study published in March 2019 in the Chinese journal National Science Review. While some experts downplayed the effects as minor, concerns linger over where the research may lead.

The goal of the work, led by geneticist Bing Su of Kunming Institute of Zoology, was to investigate how a gene linked to brain size, MCPH1, might contribute to the evolution of the organ in humans. All primates have some variation of this gene. However, compared with other primates, our brains are larger, more advanced and slower to develop; the researchers wondered whether differences that evolved in the human version of MCPH1 might explain our more complex brains.

ChatGPT Is Replacing Humans in Studies on Human Behavior—and It Works Surprisingly Well

Posted by in categories: biological, robotics/AI

The show provides a glimpse into humanity’s astonishing diversity. Social scientists have a similar goal—understanding the behavior of different people, groups, and cultures—but use a variety of methods in controlled situations. For both, the stars of these pursuits are the subjects: humans.

But what if you replaced humans with AI chatbots?

The idea sounds preposterous. Yet thanks to the advent of ChatGPT and other large language models (LLMs), social scientists are flirting with the idea of using these tools to rapidly construct diverse groups of “simulated humans” and run experiments to probe their behavior and values as a proxy to their biological counterparts.

A new type of quantum bit in semiconductor nanostructures

Posted by in categories: computing, nanotechnology, quantum physics

Researchers have created a quantum superposition state in a semiconductor nanostructure that might serve as a basis for quantum computing. The trick: two optical laser pulses that act as a single terahertz laser pulse.

A German-Chinese research team has successfully created a quantum bit in a semiconductor nanostructure. Using a special energy transition, the researchers created a state in a quantum dot—a tiny area of the semiconductor—in which an electron hole simultaneously possessed two different energy levels. Such superposition states are fundamental for quantum computing.

However, excitation of the state would require a large-scale free-electron that can emit light in the terahertz range. Additionally, this wavelength is too long to focus the beam on the tiny quantum dot. The German-Chinese team has now achieved the excitation with two finely tuned short-wavelength optical .

Breakthrough metasurface materials tech unleashes enhanced control for advanced telecommunications and beyond

Posted by in categories: materials, mobile phones

Cities can be obstacle courses for communications signals. A radio signal must travel from a cell phone to a router to a cell tower, and onward to its recipient—all while bouncing between walls, buildings and other structures. When it hits an obstacle, the radio wave gets scattered, diminishing the signal. This in turn reduces the bandwidth. At the same time, the signal must compete with the bandwidth needs of numerous other devices in the area. All this reduces the amount of information the signal can communicate.

Newly developed small, lightweight could revolutionize communications in crowded environments by providing unprecedented control over electromagnetic signals, like radio waves.

Historically, engineers have used repeaters— that receive a signal and retransmit it—to help these communications signals cover longer distances and get around obstacles, but this technology is reaching its limits. Now, engineers are looking to modify the behavior of the communications signal itself. Enter reconfigurable intelligent surfaces (RIS).
