Dr. Seol Seung-Kwon’s Smart 3D Printing Research Team at KERI and Professor Lim-Doo Jeong’s team at Ulsan National Institute of Science and Technology (UNIST) developed core technology for smart contact lenses that can implement augmented reality (AR)-based navigation, with a 3D printing process.

A smart contact lens is a product attached to the human eye like a normal lens that provides various information. Research on these lenses is currently focused mainly on diagnosing and treating health problems. Recently, Google and others are developing smart contact lenses for displays that can implement AR. Yet many obstacles to commercialization exist due to several technical challenges.

In implementing AR with smart contact lenses, electrochromic displays that can be driven with low power are necessary, and a “pure Prussian blue” color, with cost competitiveness and quick contrast and transition between colors, is attracting attention as the lens’ material. In the past, the color was coated on the in the form of a film using the electric plating method, which limited the production of advanced displays that can express various information (letters, numbers, images).

That’s exactly what researchers in Germany set out to do, making use of “acoustic holograms” to form distinct 3D shapes out of particles suspended in water — all in “one shot,” said study lead author Kai Melde, a researcher from the Max Planck Institute, in a press release.

According to a study on the work, published last week in the journal Science Advances, the researchers were able to create a helix and a figure 8 out of silica gel beads, assembled biological cells into spherical clumps, and even provided a compelling concept for forming the shape of a dove in future experiments.

These acoustic holograms work by cleverly manipulating the pressure exerted by high frequency ultrasonic waves via the inexpensive use of a conventionally 3D-printed plate.

We need to double check the answers.

By Ankita Garg: ChatGPT became popular in no time for providing accurate and good answers to any query that people have. Following this, Microsoft also announced its AI-powered Bing tool to catch on the trend and help people offer a better experience using artificial intelligence. However, the ChatGPT-powered Bing tool from Microsoft made quite a lot of mistakes and showed inaccurate results during the company’s public demo last week.

The AI-backed tool by Microsoft quoted the wrong operating margin of Gap during the demo event, according to the details revealed by engineer and writer Dmitri Brereton. The tool reported clothing brands’ operating margin as 5.9 percent; however, Gap’s earning report reveals that the margin was 4.6 percent.

CAMBRDIGE, United Kingdom — “Quantum light” may sound like something out of a Marvel movie, but scientists say it may hold the real-world key to revolutionizing science as we know it. An international team says generating this high-energy light and controlling it can unlock a whole new realm in quantum computing.

Researchers from the University of Cambridge, as well as scientists in the United States, Israel, and Austria, have come up with a theory describing this new state of light. They say it has controllable quantum properties and a wide range of frequencies which reach X-ray levels. Harnessing this power could lead to advances in microscopy — or the ability to see incredibly small things normally invisible to the naked eye.

Life looks completely different at the atomic level.

Quantum mechanics is simultaneously beautiful and frustrating.

Its explanatory power is unmatched. Armed with the machinery of quantum theory, we have unlocked the secrets of atomic power, divined the inner workings of chemistry, built sophisticated electronics, discovered the power of entanglement, and so much more. According to some estimates, roughly a quarter of our world’s GDP relies on quantum mechanics.

Yet despite its overwhelming success as a framework for understanding what nature does, quantum mechanics tells us very little about how nature works. Quantum mechanics provides a powerful set of tools for successfully making predictions about what subatomic particles will do, but the theory itself is relatively silent about how those subatomic particles actually go about their lives.

QuEra Computing, maker of the world’s first and only publicly accessible neutral-atom quantum computer—Aquila—today announces its research team has uncovered a method to perform a wider set of optimization calculations than previously known to be possible using neutral-atom machines.

The findings are the work of QuEra researchers and collaborators from Harvard and Innsbruck Universities: Minh-Thi Nguyen, Jin-Guo Liu, Jonathan Wurtz, Mikhail D. Lukin, Sheng-Tao Wang, and Hannes Pichler.

“There is no question that today’s news helps QuEra deliver value to more partners, sooner. It helps bring us closer to our objectives, and marks an important milestone for the industry as well,” said Alex Keesling, CEO at QuEra Computing. “This opens the door to working with more corporate partners who may have needs in logistics, from transport and retail to robotics and other high-tech sectors, and we are very excited about cultivating those opportunities.”
