Diversifying Aquaculture

You are in a restaurant and the server comes up to take your order. You think about getting grilled steak, but you decide to go with some seafood-- or more specifically, fish.

Largest Known Prime Number Discovered

Luke Durant found the largest prime number in October of 2024. It contains 41,024,320 digits. The number was 2136279841-1 on GIMPS. Luke Durant, a 36-year-old NVIDIA employee, used GPUs to conclude that 2136279841-1 is prime. Durant is a member of the Great Internet Mersenne Prime Search (GIMPS). GIMPS has named this number M136279841 instead of the actual number (because the actual amount would be too large to write). Durant’s number beats the previous number (discovered in 2016) in digits, by 16,000,000 digits. He was in a line at the airport when he found that one of his supercomputers had come out with a number that was probably prime. He says he “wasn’t as excited as I could be about finding the number."

Researcher Kylie Maguire from CSIRO sits in front of a large computer screen.

Kylie recognises what it is: an underwater nursery for the Antarctic skate! Her colleagues all stare at their own computer screens, peering at the images taken by the underwater picture takers Marimba, UMI and IMOS. This scene shows use of the IMOS (Integrated Marine Observing System) and the UMI (Understanding of Marine Imagery project) which are showing the underwater world to scientists and the general public and building on to different projects.

Old Clothes are Recycled into Concrete

Over 200,000 tonnes of textiles end up in Australian landfills. A team at RMIT University in Melbourne Australia have found a way to lower this number. David Law, Chamila Gunasekara, Shadi Houshyar, Sujeeva Setunge and Nayanatara Ruppegoda Gamage are all part of the team that used old textiles as a material in concrete to help reduce cracks and boost the durability of it.
