PsiQuantum presses ahead with photon-based large-scale quantum computer
Quantum computing company PsiQuantum is accelerating efforts to build a large-scale quantum computer using photons. It is pursuing an approach that makes chips in existing semiconductor production facilities and connects about 100 cooling cabinets to implement a practical-scale system. Founded in 2016 by four physicists from British universities, the company has raised $1 billion and begun work on a Chicago hub, while preparing a second hub in Australia.

Seoul National University professor Roh Seong-hoon wins July Korea Science and Technology Award
Roh Seong-hoon (노성훈), a professor in the Department of Biological Sciences at Seoul National University, was selected as the July recipient of South Korea\'s Science and Technology Award, the Ministry of Science and ICT and the National Research Foundation of Korea said on Tuesday. Roh identified how a \"chaperone regulator\" regenerates the cytoskeleton by selecting, assembling and recycling tubulin. He used cryo-electron microscopy to analyse tubulin-chaperone binding at atomic level.

Gut microbes directly produce \'happiness hormone\' serotonin, probiotic pairing is key
Gut microbes previously seen as only indirect helpers of intestinal cells can directly produce serotonin, often called the “happiness hormone,” according to research. The study found serotonin is synthesised only when two Lactobacillus-related probiotic strains work together, not when cultured separately. Animal tests reproduced the mechanism. The findings may offer clues for identifying and treating irritable bowel syndrome, which affects 7 to 10 percent of South Korea’s population.
