Around 2500 years ago, a star ejected most of its gas, forming the beautiful Southern Ring Nebula, NGC 3132, chosen as one of the first five image packages from the James Webb Space Telescope (JWST).
Alan Cowman wins $50,000 CSL Florey Medal for Lifetime Achievement for revealing how malaria parasites infect humans, paving the way for new drugs and vaccines for a disease that infects more than 240 million people a year, and keeps communities in poverty.
Past CSL Florey Medallists include Graeme Clark, Ian Frazer, Ruth Bishop, and Nobel Laureates Barry Marshall and Robin Warren.
Melbourne scientist Professor Alan Cowman AC has worked to understand how the malaria parasite Plasmodium falciparum causes disease in humans and how it evolves to outwit antimalarial drugs. He has also created genetic tools to modify the parasite, which have been used by malaria researchers worldwide.

Researchers working with stem cells to restore sight and fight blood cancers are the two winners of the 2022 Metcalf Prizes for Stem Cell Research, awarded by the National Stem Cell Foundation of Australia.

Dr Anai Gonzalez-Cordero research aims to restore sight in people with inherited retinal diseases, by repairing or replacing damaged photoreceptor (light-sensing) cells in the eye.
She has already shown that she can grow cultures of healthy photoreceptor cells in a dish in the lab and then use the cells replace the defective cells and restore sight in laboratory models of hereditary blindness. And she has shown that gene therapy can repair diseased human retinal cells grown in the lab as ‘mini-organs’ (or ‘organoids’), providing them with normal light-sensing ability.
Her $55,000 Metcalf Prize will contribute to developing systems to progress both concepts towards clinical trials. She is based at Children’s Medical Research Institute (CMRI) in Western Sydney.

Dr Ashley Ng is revealing how blood stem cells are controlled, and how they sometime go rogue, leading to blood cancers. He has discovered how a protein known as ‘ERG’ underpins healthy development of blood cells, and how it also plays a role in Down syndrome-associated leukaemia and a range of other blood cancers.
As a researcher at WEHI and a clinician at the Royal Melbourne Hospital and Peter Mac, Ashley will use his $55,000 Metcalf Prize to advance his ideas from the laboratory into treatments for blood and blood cancer diseases.

The alignment between galaxy spins and the large-scale structure of the universe reveals the processes by which different components of galaxies form.
Like our own Milky Way, most galaxies have two components: an extended disk in which new stars form from gas and a central bulge of mostly older stars that grows over time.
An observational study recently published in Monthly Notices of the Royal Astronomical Society found that the size of the galaxies’ bulge changes how their spins align with the surrounding structure.

Earlier this year a machine learning algorithm identified up to 5,000 potential gravitational lenses that could transform our ability to chart the evolution of galaxies since the Big Bang.
Now astronomer Kim-Vy Tran from ASTRO 3D and UNSW Sydney and colleagues have assessed 77 of the lenses using the Keck Observatory in Hawai’i and Very Large Telescope in Chile. She and her international team confirmed that 68 out of the 77 are strong gravitational lenses spanning vast cosmic distances.

Planetary scientist Katarina Miljkovic is available to discuss the nature of planets in Brisbane this week. She will give free public talks on Thursday 29 September and Friday 30 September. It’s part of a national tour of public and school talks promoting opportunities for women in physics.
The planets in our solar system are vastly different although they all formed from the same cloud of gas and dust around a star – our sun. Why is this?
Associate Professor Katarina Miljkovic thinks the answers lie in studying how asteroids, comets and meteors bombarded the planets in the past, changing the surface conditions.
She works at Curtin University’s Space Science and Technology Centre and School of Earth and Planetary Sciences and uses data from several NASA missions.
