Self-supervised AI learns physics to reconstruct microscopic images from holograms      (via sciencedaily.com) 

Researchers have unveiled an artificial intelligence-based model for computational imaging and microscopy without training with experimental objects or real data. The team introduced a self-supervised AI model nicknamed GedankenNet that learns from physics laws and thought experiments. Informed only by the laws of physics that universally govern the propagation of electromagnetic waves in space, the researchers taught their AI model to reconstruct microscopic images using only random artificial holograms -- synthesized solely from 'imagination' without relying on any real-world experiments, actual sample resemblances or real data.

Robots cause company profits to fall -- at least at first      (via sciencedaily.com) 

Researchers have found that robots can have a 'U-shaped' effect on profits: causing profit margins to fall at first, before eventually rising again. The researchers studied industry data from the UK and 24 other European countries between 1995 and 2017, and found that at low levels of adoption, robots have a negative effect on profit margins. But at higher levels of adoption, robots can help increase profits.

GPT-3 can reason about as well as a college student, psychologists report      (via sciencedaily.com) 

The artificial intelligence language model GPT-3 performed as well as college students in solving certain logic problems like those that appear on standardized tests. The researchers who conducted the experiment write that the results prompt the question of whether the technology is mimicking human reasoning or using a new type of cognitive process. Solving that question would require access to the software that underpins GPT-3 and other AI software.

Researchers tickle rats to identify part of the brain critical for laughter and playfulness      (via sciencedaily.com)     Original source 

To study play behaviors in animals, scientists must be able to authentically simulate play-conducive environments in the laboratory. Animals like rats are less inclined to play if they are anxious or restrained, and there is minimal data on the brain activity of rats that are free to play. After getting rats comfortable with a human playmate, tickling them under controlled conditions, then measuring the rats' squeaks and brain activity, a research team reports that a structure in rat brains called the periaqueductal gray is essential for play and laughter.

Bacteria as Blacksmiths      (via sciencedaily.com)     Original source 

A hot bath is a place to relax. For scientists, it is also where molecules or tiny building blocks meet to form materials. Researchers take it to the next level and use the energy of swimming bacteria to forge materials. A recent study shows us how this works and the potential sustainability benefits that may arise from this innovative approach.
