Electrons can help infer laser intensities that are too high to measure using conventional methods.

In a world filled with endless connections and constant communication, the relationship between loneliness and aloneness is not always clear. Now, University of Arizona researchers have analyzed that relationship—and found that they are two different things that are not closely correlated.

People don’t feel lonely until they spend three-quarters of their time alone, the study found. However, when their alone time goes beyond 75%, it becomes difficult for them to avoid feelings of loneliness.

Published in the Journal of Research in Personality in September, the study also concludes that among older adults, there is a particularly strong association between time spent alone and feeling lonely. The study was led by Alex Danvers, a former postdoctoral associate at UArizona, and Liliane Efinger, a former visiting graduate student.

Researchers from Tsinghua University, China, have developed an all-analog photoelectronic chip that combines optical and electronic computing to achieve ultrafast and highly energy-efficient computer vision processing, surpassing digital processors.

Computer vision is an ever-evolving field of artificial intelligence focused on enabling machines to interpret and understand visual information from the world, similar to how humans perceive and process images and videos.

It involves tasks such as image recognition, object detection, and scene understanding. This is done by converting analog signals from the environment into digital signals for processing by neural networks, enabling machines to make sense of visual information. However, this analog-to-digital conversion consumes significant time and energy, limiting the speed and efficiency of practical neural network implementations.

They also recognised that AI itself may exhibit certain biases, and different settings it was deployed with were able to dramatically change output, in extreme cases rendering it unusable. In other words, setting the bots up correctly is a prerequisite to success. At least today.

So, for the time being, I think we’re going to see a rapid rise in human-AI cooperation rather than outright replacement.

However, it’s also difficult to escape the impression that through it we will be raising our successors and, in not so distant future, humans will be limited to only setting goals for AI to accomplish, while mastering programming languages will be akin to learning Latin.

Researchers at the University of Wisconsin–Madison and Academia Sinica of Taiwan have harnessed a combination of lab-grown cells to regenerate damaged heart muscle.

The study is published in Circulation. It addresses major challenges of using heart muscle cells, called cardiomyocytes, grown from stem cells, and takes a crucial step toward future clinical applications.

Previous research has shown that transplanting cardiomyocytes made from induced pluripotent stem cells (iPSC) can replace muscle in the hearts of mammals. Researchers have struggled to bring the treatment to the clinic, in part because the implanted cells haven’t developed enough life-sustaining blood vessels to survive very long.
