Graphene scientists from The University of Manchester have created a new ‘nano-petri dish’ using a two-dimensional (2D) material to create a new method of observing how atoms move in a liquid. Published in the journal Nature, a team led by researchers based at the National Graphene Institute (NGI) used stacks of 2D materials such as graphene to trap liquids to better understand how the presence of liquids changes the behavior of solids. The team was able to capture images of a single atom ‘swimming’ in a liquid for the first time. These findings could have far-reaching implications for the future development of green technologies such as hydrogen production. When a solid surface comes into contact with a liquid, the two substances change their configuration in response to the proximity of the other. Such atomic-scale interactions at the solid-liquid interface regulate the behavior of batteries and fuel cells for clean electricity generation, as well as determin...

This time last year, most Australians stayed at home, perhaps taking solace in the performance of the Australian swimming team, which took home multiple gold medals from the Tokyo Olympics. This year, we can expect more as the Dolphins face the best swimmer at the Commonwealth Games in Birmingham. The team had successfully won the world championship in Budapest in June and stayed together for training camp in France before starting their assault on the Birmingham pool. Once again, the team will be led by a group of extraordinary women who have taken the world by storm: Emma McKeon, Ariarne Titmus and Kaylee McKeown will be joined by Australia’s newest teen swimming superstar, Mollie O’Callaghan. Australian women have posted the fastest Commonwealth times this year in 12 of the 16 races at the Birmingham programme, and that doesn’t take into account McKeon, who has taken a lot of time off this year but will return for the Olympics. Even so, head coach Rohan Taylor is re...

And she sure looks happy. Just like the sponsors who have invested millions of dollars in the two athletes; with broadcasters, women’s magazines and mainstream media off the sports page, it all piles up. Simpson has even launched his own fashion line. The more news about the McKeon-Simpson relationship (which certainly deserves a portmanteau celeb? Codem? Maybe Emody?), the greater the return on sponsor investment, and at a time when competition for corporate endorsements is fierce. After his victory at the Tokyo Olympics, manager McKeon Tony Box revealing sponsorship has changed dramatically since the times Ian Thorpe shaken in the millions, telling PS last year: “There’s more competition and sports and athletes who don’t provide regular content have suffered.” “Content” is one thing that “Emody” will not lack, especially if Simpson’s social media posts are any indication, as is being filmed – allegedly clandestinely...

On a cold Melbourne winter night, Em Fox braves the cold for a leg workout. Key points: Last month, FINA voted to limit the participation of transgender women in elite women’s competitions Dr Ada Cheung says the debate around transgender athletes is disproportionate to the perceived problem While some athletes are concerned about the impact of FINA’s policies, others are broadly supportive He is happy to be here because 10 years ago he thought he would never play again. “2012 was the last year I played in the men’s soccer competition,” he said. “I’ve always found playing in the men’s team challenging, even though I may have come across as an outwardly masculine identity. “It wasn’t how I felt, and being in a hyper-masculine environment was very uncomfortable. “So when I decided not to play football anymore I thought it would have a lot of finality.” She went on to become the first openly transgender woman in the wom...
