A research team led by Lawrence Berkeley National Laboratory (Berkeley Lab) has developed “supramolecular ink,” a new technology for use in OLED (organic light-emitting diode) displays or other electronic devices. Made of inexpensive, Earth-abundant elements instead of costly scarce metals, supramolecular ink could enable more affordable and environmentally sustainable flat-panel screens and electronic devices.

“By replacing precious metals with Earth-abundant materials, our supramolecular ink technology could be a game changer for the OLED display industry,” said principal investigator Peidong Yang, a faculty senior scientist in Berkeley Lab’s Materials Sciences Division and professor of chemistry and materials science and engineering at UC Berkeley.

“What’s even more exciting is that the technology could also extend its reach to organic printable films for the fabrication of wearable devices as well as luminescent art and sculpture,” he added.

Language models offer promises in encoding quantum correlations and learning complex quantum states. This Perspective discusses the advantages of employing language models in quantum simulation, explores recent model developments, and offers insights into opportunities for realizing scalable and accurate quantum simulation.

Summary: A new study identified a crucial link between anxiety disorders and the brain receptor TACR3, as well as testosterone. This groundbreaking research found that rodents with high anxiety had low TACR3 levels in the hippocampus, a key area for learning and memory.

Notably, the study showed that testosterone deficiency-related anxiety could be addressed by targeting TACR3. This discovery opens new therapeutic possibilities for treating anxiety disorders, especially in individuals with hypogonadism.

A team of MIT researchers has found that in many instances, replacing human workers with AI is still more expensive than sticking with the people, a conclusion that flies in the face of current fears over the technology taking our jobs.

As detailed in a new paper, the team examined the cost-effectiveness of 1,000 “visual inspection” tasks across 800 occupations, such as inspecting food to see whether it’s gone bad. They discovered that just 23 percent of workers’ total wages “would be attractive to automate,” mainly because of the “large upfront costs of AI systems” — and that’s if the automatable tasks could even “be separated from other parts” of the jobs.

That said, they admit, those economics may well change over time.

The first vertical takeoff and landing test (VTVL) for the Zhuque-3 reusable methane-powered carrier rocket was successfully conducted in the Gobi Desert in northwestern China on Friday afternoon, according to its developer LandSpace, a Chinese commercial aerospace company.

The company said that the test flight lasted for about 60 seconds, with the trial rocket reaching a height of approximately 350 meters above the ground. The rocket landed 100 meters away from the liftoff point with a precision of about 2.4 meters.

The company said that the full-sized trial rocket prototype verified the key technologies for the first stage of Zhuque-3, which is set to be launched in 2025. These technologies include variable-thrust technology with a wide range and landing guidance and control.
