Credit: Natural Hazards and Earth System Sciences (2024). DOI: 10.5194/nhess-24-47-2024 Scientists have successfully applied a pair of advanced computer models to simulate last year's wildfire that devastated the Hawaiian town of Lahaina. The development could lay the groundwork for more detailed predictions of wildfires that advance into towns and cities, eventually helping with firefighting efforts and safer evacuations as…

UK startup Phasecraft has developed an algorithm that brings the promise of quantum computers’ potential to reveal new materials and their properties much closer to realisation.  Due to their ability to simulate multiple complex quantum systems, quantum computers hold incredible potential in the field of material science. In turn, this could lead to technological leaps in fields such as energy, manufacturing, and medicine.  There is still a long way to go for quantum computers to scale and…

SimSpace, a startup that creates digital replicas of organizations’ tech and networking stacks for cybersecurity training, has raised $45 million in a funding round led by L2 Point Management. Bringing the company’s total raised to $70 million, the investment comes at an auspicious time for SimSpace, which had been entirely bootstrapped until about two years ago. SimSpace is on its way to hitting its annual recurring revenue goal of $50 million by the end of fiscal year 2023, according to…

UK indie studio Hello Games is building something that it's calling "more ambitious" than No Man's Sky. The studio's next game is Light No Fire, and it brings procedural generation to an entire planet on an incredibly detailed scale.Light No Fire is an open-world exploration and community-building game set on a planet the size of Earth, blending RPG elements with sandbox survival. It's a multiplayer experience in an ancient and fantastical landscape, with climbable trees, hills and mountains, and secrets to discover at…

Red and blue areas show wind speed differences within the turbulence caused by Kelvin–Helmholtz instability. Credit: Ryoichi Yoshimura A research group from Nagoya University has accurately simulated air turbulence occurring on clear days around Tokyo using Japan's fastest supercomputer. They then compared their findings with flight data to create a more accurate predictive model. The research was reported in the journal…

Multivariate K-means clustering analysis results for 4 clusters. a The clustering map shows spatial distribution, and (b) the column chart summarizes normalized indicators of displacement disparity for each cluster. c The separate clustering maps show the spatial distribution of each cluster. The clustering indicators are DOD (Difference of direction), DOV (Difference of velocity), SD (Separation distance) and SS (Skill score). Credit: Nature…

Given N chairs are arranged in a circle, and M people are standing in the circle facing the chairs. When the music starts playing, the people start walking around the circle of chairs in a clockwise direction. After each round of music, one person from each pair of adjacent people sits in a chair. The music stops after K rounds, and the remaining people take unoccupied chairs, the task is to Determine the final positions of each person after the K rounds of the music.Note: If a person with the number i is in the jth…

In 1971, 19-year-old musician Paul Southwell left Accrington and headed for the bright lights. At that time London’s gay scene consisted of a selection of seedy pubs, after-hours basement drinking dens and regular discos organised by the Gay Liberation Front, which had formed the previous October. But none of the acts playing GLF events were out: most of the entertainment was supplied by decidedly straight bands.Southwell would change that. Alongside Dave Jenkins and Alan Jordan, he formed Handbag, a powerpop band whose…

I first met John Lennon in 1975, backstage at a televised event in New York when I was staff photographer for the SoHo Weekly News. Years later, while I was still at the paper, we decided to run an interview with Yoko Ono ahead of the release of the couple’s new album, Double Fantasy. They had spent the previous five years as recluses, during which time they had their son, Sean. I didn’t know Yoko personally but I’d always had a lot of respect for her as an artist, and of course I was a big fan of John’s. The idea was…
