• Lab Notes: Why aurora season isn't over yet

  Astrophotographers have had another great month, with the aurora australis lighting up night skies as far north as southern Queensland.And while you might've heard that the best of this bunch of auroras is behind us, don't put your camera away just yet. There's good reason to think the southern lights will illuminate the sky well into 2026.It all depends on what the Sun shoots in our direction … and we might find ourselves in the firing line more often over the next few months.Featuring:Brett Carter, space weather researcher at RMIT UniversityMore information:The Sun Reversed Its Decades-long Weakening Trend in 2008When the southern lights are seen further north

• Lab Notes: How are long-range weather forecasts made?

  It looks like most of Australia is in for a warmer-than-usual summer this year.That's according to the Bureau of Meteorology's long-range forecast, which was released in October.So — without a crystal ball — how do meteorologists make weather predictions so far out, how accurate are they, and how is climate change affecting them?You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia). You'll find episodes on animal behaviour, human health, space exploration and so much more.Get in touch with us: [email protected]:Karl Braganza, National Manager of Climate Services at the Bureau of MeteorologyMore information:BOM's first long-range summer forecast shows increased chance of extreme heat

• Bragg winners for science writing, more from the Prime Minister’s Prizes for Science and water droplets used for geoengineering

  In just 75 years the Earth’s average temperature is predicted to be close to 3 degrees above pre-industrial levels. We are in the fast lane to a different world, one that will not be friendly to the current range of plants and animals, including humans. The race is on to cool our overheating planet.

• Lab Notes: How breastfeeding can protect against cancer

  Thanks in part to 18th-century nuns, we now know that having children and breastfeeding reduces a mum's risk of developing breast cancer for years, even until her kid is well into primary school.Now Australian scientists have discovered how breastfeeding specifically enlists the immune system to protect against an aggressive and hard-to-treat type of breast cancer.You can binge more episodes of the Lab Notes podcast with science journalist and presenter Belinda Smith on the ABC Listen app (Australia).
