  • How Two Students Fixed the Focus of James Webb from Earth with Prof. Peter Tuthil, Dr. Louis Desdoigts & Max Charles (468)
    Apr 4 2026

    When a problem with the James Webb Space Telescope left its images frustratingly out of focus, the solution wasn't fixed in space... it was fixed from Earth. At the University of Sydney, PhD students Dr. Louis Desdoigts and Max Charles spent two years rewriting and refining code to recalibrate a critical instrument designed by Professor Peter Tuthill: the Aperture Masking Interferometer.

    Their breakthrough sharpened the telescope's infrared vision unlocking clearer views of distant worlds, including volcanic activity on Io, one of Jupiter's moons. In a fitting tribute, the pair even got matching tattoos of the hardware they helped fix!

    Not only did their work restore clarity to one of humanity's most powerful observatories, it also saved NASA the immense cost and impossibility of repairing the telescope in space.

    Mar 28 2026

    This episode features Dr. Linzi Wilson-Wilde and Hannah Jarman discussing the realities of forensic science beyond shows like CSI. Through cases such as the Phantom of Heilbronn case and Lindy Chamberlain-Creighton, they explore how flawed evidence and forensic myths have contributed to wrongful convictions. They also examine common misconceptions around techniques like bite mark analysis, fire investigation, and glass evidence. The conversation emphasises the importance of approaching forensic science holistically, recognising it as just one piece of the broader investigative puzzle.
