Massive implications with this one.
It’s been a rough few days in the condensed matter physics realm following claims of the world’s first room-temperature superconductor being achieved. However, work to verify and replicate the results.
Transparent electronic devices could have numerous valuable real-world applications. Among other things, they could enable the creation of new optical devices, smart gear or wearables, invisible solar panels and integrated communication systems.
Researchers at Xidian University, Southeast University and Wuhan University of Technology recently developed new, highly promising, transparent metadevices based on quasi-one-dimensional surface plasmon polariton (quasi-1D SPP) structures. These devices, introduced in a paper published in Nature Electronics, could be used to develop optically and radiofrequency transparent wireless communication systems and other promising technologies.
“Transparent and invisible electronic device is a fascinating goal that scientists and engineers are enthusiastically pursuing,” Prof. Bian Wu, one of the researchers who carried out the study, told Tech Xplore. “Currently, transparent electronics typically rely on the intrinsic properties of optically conductive materials, which are not radiofrequency transparent and have low operating efficiency. SSPs can be used to concentrate, channel and enhance energy. However, the use of SPPs in the development of optical and radiofrequency transparency remains blank.”
Apple CEO Tim Cook says he isn’t afraid of criticism. Here’s how he’s learned to handle negative feedback.
Meta’s new Twitter competitor, Threads, is looking for ways to keep users interested after more than half of the people who signed up for the text-based platform stopped actively using the app, Meta CEO Mark Zuckerberg reportedly told employees in a company town hall yesterday. Threads launched on July 5 and signed up over 100 million users in less than five days, buoyed by user frustration with Elon Musk-owned Twitter.
“Obviously, if you have more than 100 million people sign up, ideally it would be awesome if all of them or even half of them stuck around. We’re not there yet,” Zuckerberg told employees yesterday, according to Reuters, which listened to audio of the event.
Third-party data suggests that Threads may have lost many more than half of its active users. Daily active users for Threads on Android dropped from 49 million on July 7 to 23.6 million on July 14, and then to 12.6 million on July 23, web analytics company SimilarWeb reported.
MySpace gave us co-founder Tom right off the bat: join the social network and you started with at least one friend, even if he never interacted with you. Now social platforms like Snapchat and Facebook are using generative artificial intelligence to give us smarter and more engaging friends.
When Facebook parent company Meta reported financial results last week, CEO Mark Zuckerberg said he saw the AI friend as an assistant or coach that “can help you interact with businesses.” Facebook’s AI chatbots will reportedly offer a range of personalities and capabilities, presumably in the hope that at least one will appeal to most if not all Facebook users.
According to Financial Times reporting, Zuckerberg is “spending all his energy and time” on this: a massive shift from the metaverse and virtual reality, his previous idée fixe.
It’s no secret that AI chatbots like OpenAI’s ChatGPT have a strong tendency to make stuff up. They’re just as good at inventing facts as they are assisting you with work — and when they mix up the two, disaster can strike.
Whether the people creating AI can fix that issue remains up for debate, the Associated Press reports. Some experts, including executives who are marketing these tools, argue that these chatbots are doomed to forever cook up falsehoods, despite their makers’ best efforts.
“I don’t think that there’s any model today that doesn’t suffer from some hallucination,” Daniela Amodei, co-founder and president of Anthropic, maker of the AI chatbot Claude 2, told the AP.

Wearable electronic devices are playing a rapidly expanding role in the acquisition of individuals’ health data for personalized medical interventions; however, wearables cannot yet directly program gene-based therapies because of the lack of a direct electrogenetic interface. Here we provide the missing link by developing an electrogenetic interface that we call direct current (DC)-actuated regulation technology (DART), which enables electrode-mediated, time-and voltage-dependent transgene expression in human cells using DC from batteries. DART utilizes a DC supply to generate non-toxic levels of reactive oxygen species that act via a biosensor to reversibly fine-tune synthetic promoters.
