Exhibit about history of universe opens at TWOSE
A person explores Telus World of Science Edmonton's "Stardust: The Universe in You" exhibit on May 30, 2025. (Darcy Seaton / CTV News Edmonton) Telus World of Science Edmonton's newest exhibit will offer a chance to explore the oldest parts of the universe's history when it opens on Saturday. 'Stardust: The Universe in You' covers the big bang, or the universe's birth, the creation of stars, and leading research from the James Webb Space Telescope into infrared light. 'It explores basically what is in all of us. How did all the atoms in our universe get their start? How do we go from the big bang to these complex organic molecules that we have here on the earth?' said Frank Florian, the senior manager of planetarium and space science at TWOSE. 'Science itself is always this evolving structure. As we learn new things about the universe, we have to change the way we look at things in the universe itself. So this (exhibit) here creates a bit of an eye-opening experience – and maybe creates more questions than answers.' The exhibit's interactive features include triggering a supernova, creating a galaxy, walking through a star explosion and experimenting with infrared.

What We Are Reading Today: ‘Becoming Earth'
Author: Ferris Jabr Published in 2024 and written by Ferris Jabr, 'Becoming Earth' talks about how the planet we know and live in started and came to life. One of the significant thoughts Jabr argues through his book is the idea that billions of years ago, life transformed from a collection of orbiting rocks into what we now know as our cosmic oasis. This process released oxygen into the atmosphere, formed seas and oceans, and shaped rocks into fertile soil. Through the book, the author also discusses various environmental systems and how they operate. He talks about the roles of microbes in shaping continents, the Amazon rainforest's self-sustaining rain cycle and the impact of human activities on planetary systems, all connected to other natural events. Surprisingly, as Jabr discusses the disadvantages of human activity leading to environmental crises, he also highlights the importance of humans in improving ecosystems. Despite the negative impacts people have had on the environment, humanity has expended a great deal of energy to understand and mitigate environmental problems, he argues. However, the book has received some criticism, with reviewers arguing that Jabr may have conflated his personal perspective on Earth with scientific research and evidence in the process of using metaphors to explain science. Other reviewers said that a few sections of 'Becoming Earth' may need improvement and more in-depth scientific evidence to support the conclusions Jabr makes.

How should government tackle the quantum conundrum?
Lots of discussion and debate about net zero commitments and obligations this week. But for this week's Insiders On Background, let's explore what the Australian economy looks like under a net-zero scenario. How will it differ from today's resources-heavy economy? Is the answer artificial intelligence and quantum computing? Former chief scientist Cathy Foley joined David Speers to talk about the emerging technologies and quantum literacy.

Scientists finally work out how clapping hands generates sound
A study has unravelled the physics behind the sound of hand claps, revealing it's more complex than just hands hitting each other. The sound is generated by a pocket of air compressed between the hands and rapidly expelled, causing air molecules to vibrate, similar to the Helmholtz resonance principle. Researchers used live experiments, theoretical modelling, and silicone replicas of hands, modifying speed, shape, and skin softness to understand clapping. The elasticity of hands causes energy absorption, resulting in a short "pop" sound rather than a longer noise. Researchers suggest clapping could potentially be used for human identification due to the unique sound and frequency of each person's clap.

White House MAHA Report may have garbled science by using AI, experts say
Some of the citations that underpin the science in the White House's sweeping 'MAHA Report' appear to have been generated using artificial intelligence, resulting in numerous garbled scientific references and invented studies, AI experts said Thursday. Of the 522 footnotes to scientific research in an initial version of the report sent to The Washington Post, at least 37 appear multiple times, according to a review of the report by The Washington Post. Other citations include the wrong author, and several studies cited by the extensive health report do not exist at all, a fact first reported by the online news outlet NOTUS on Thursday morning.
