Recently, a research group led by Prof. Peng Tong from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), significantly improved the negative thermal expansion (NTE) effect of Cu2P2O7, a new but excellent NTE material, and prepared a zero thermal expansion (ZTE) Cu2P2O7/2024Al composite with high specific thermal conductivity and good machinability.

The research results were published in Journal of Materials Science & Technology and Ceramics International.

With the advancement of high-tech fields, it is not possible to adjust the dimensions of precision equipment. However, thermal expansion with temperature is a of many regularly used materials that is difficult to control. Combining NTE materials with ordinary positive materials is an efficient way to produce ZTE materials.

Right in time for spooky season, scientists have discovered the existence of something called the “demon” particle. While the name of the material may strike terror in some, its discovery is actually far less sinister. Hidden from researchers for over seven decades, the “composite” of electrons was recently discovered according to a new study published in Nature.

“Demons have been theoretically conjectured for a long time, but experimentalists never studied them,” paper senior author Peter Abbamonte said in the study. “In fact, we weren’t even looking for it. But it turned out we were doing exactly the right thing, and we found it.”

This talk was given at a local TEDx event, produced independently of the TED Conferences. Stella Davies asks a powerful question: If you could save the life of a child with 2 hours of your time-would you? Her talk is inspiring and encouraging. Depending on the kindness of strangers is shown throughout this talk. We have a profound impact on what we can do for each other even if we don’t know each other. Stella was born in Liverpool, England. She came to the USA in 1989, planning to stay for a year and learn more about bone marrow transplantation. Three weeks after arrival she met her American husband and has been in the US ever since. Stella is now the director of the bone marrow transplant program at Cincinnati Children’s Hospital.

About TEDx, x = independently organized event In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

The need for modern technologies to dismantle existing underwater infrastructure is growing due to increasing demand for renewable energy sources. For example, to bring a wind power plant in the sea up to higher powers, the existing old steel frames, which may be below sea level, must first be dismantled so that engineers can rebuild them to obtain these higher powers.

In laboratory tests, researchers at the Fraunhofer Institute for Material and Beam Technology IWS (Fraunhofer IWS) have developed a shortwave green laser method for beneath-sea cutting that offers multiple advantages over commonly used techniques that use saws, automatic saw wires, and plasma cutters, for example.

According to the researchers, the technique is possible because of the availability of shortwave green lasers in the more-than-1-Kw-class, which are required to achieve the necessary cutting power. In the future, the researchers said, shorter-wavelength versions with blue lasers are conceivable.

Sal Khan, the founder and CEO of Khan Academy, thinks artificial intelligence could spark the greatest positive transformation education has ever seen. He shares the opportunities he sees for students and educators to collaborate with AI tools — including the potential of a personal AI tutor for every student and an AI teaching assistant for every teacher — and demos some exciting new features for their educational chatbot, Khanmigo.

Here’s my new article for Aporia magazine, the final futurist story in my 4-part series for them!

Written by Zoltan Istvan.

I met my wife on Match.com 15 years ago. She didn’t have a picture on her profile, but she had written a strong description of herself. It was enough to warrant a first date, and we got married a year later.

But what if ordinary dating sites allowed users to see their potential date naked using advanced AI that could “virtually undress” that person? Let’s take it a step further. What if they gave users the option to have virtual sex with their potential date using deepfake technology, before they ever met them in person? Some of this technology is already here. And it’s prompting a lot of thorny questions – not just for dating sites but for anyone who uses the web.

Researchers at Max Planck Institute of Quantum Optics (MPQ) and Technical University of Munich (TUM) demonstrated a potential platform for large-scale quantum computing and communication networks. Secure quantum networks are of interest to financial institutions, medical facilities, government agencies, and other organizations that handle personal data and classified information due to their much higher level of security.

To create an environment that supported quantum computing, the researchers excited individual atoms of the rare-earth metal erbium. The excitation process caused the erbium atoms to emit single photons with properties suitable for the construction of quantum networks.
