Madeleine Beekman argues for a new origin of language: the need to share childcare.

New technology is allowing long chains of DNA to be manipulated opening the door for the creation of new life forms. 

A 10% honey solution can stop growth of bacteria. And strong impacts on common fungal infections have also been observed.

Despite the move to sustainable fuel in F1 car racing, the fuel powering cars cannot be tracked easily, and only amounts to 1% of the energy cost in staging a race.

Australia has the highest melanoma rates in the world — but there's some good news for Aussie kids. The presence of moles is a strong predictor of melanoma and researchers in Queensland have found that the number of moles found on children's bodies has halved in recent decades.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

Major international airports in the Middle East have been closed this week due to the war with Iran, leaving hundreds of thousands of passengers stranded.

Dr John Bolton, once of the Radiophysics Laboratory in the CSIRO to conduct secret research on radar for the military, also helped pioneer radio astronomy after the Second World War. He was invited to Caltech to show them how to build radio telescopes — but then resigned and returned to Australia to build the legendary Parkes Telescope. Guest Jonas Zmuidzinas  Professor of physics  Director of Caltech Optical Observatories  Caltech PresenterRobyn Williams

Harriet Brettle studied finance, had several varied jobs in leadership, and now heads the Keck Institute for Space Studies at Caltech. Like the “professor of everything” Bob May from Australia, who once combined his mathematical physics with the head of the Bank of England, Harriet can take risks with projects based on knowing both what’s worthwhile scientifically and sensible financially. Guest Harriet Brettle Executive director of the Keck Institute for Space Studies Caltech PresenterRobyn Williams

When raised lead levels were noticed in Los Angeles last year, Professor Francois Tissot, who usually examines the chemistry of asteroids, quickly saw that the fires that ravaged the region in January 2025 were to blame. He reveals the current extent of the concern and suggests Australia inspects its own burned regions too. Guest Francois Tissot Professor of geochemistry Caltech PresenterRobyn Williams

How do you establish a telescope? For Caltech astrophysicist Professor Jonas Zmuidzinas, the answer involves time, money, and incredibly sensitive detectors that can pick up everything from water in the dusty discs around young stars to galaxies in the far reaches of the Universe. 

Shortly after the Hubble Space Telescope launched in 1990, astronomers realised its primary mirror, designed to focus minute amounts of light from distant planets, stars and galaxies, had the wrong curve. 

A likely successor for Jane Goodall is Professor Cat Hobaiter, who’s based at the University of St Andrews in Scotland. She told the AAAS audience of her finding the 6,000-year-old mummies of baboons in Egypt. But there are no wild baboons there — so where did those dead creatures come from?  

Phoenix is an unexpected city: It is where the Jane Goodall papers and archive are kept, at the wide, shining campus of the Arizona State University. 

The editor-in-chief of the Journal of the American Medical Association (JAMA), Professor Kirsten Bibbins-Domingo, explains how she reports on the science of health care without inflicting too much political noise on her readers — mostly clinicians.

The American Association for the Advancement of Science (AAAS) was founded in 1848 and this year faced its greatest crisis — a proposed cut to research in the US of around 50 per cent, threatened by the Trump administration. What if the cuts had gone through? 

Backyard sprinklers have transformed the Aussie urban landscape. But their path to domination of our suburbs was haphazard — and hinged on the inventions of several knockabout tinkerers. Meanwhile with a rapidly drying climate, we may need to re-consider our reliance on this invention.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

With an estimated 200 million feral rabbits hopping around Australia, are current viral controls working, and do we need another virus to knock off these invasive pests?

Australia was once home to kangaroos that weighed as much as a quarter of a tonne. A new fossil analysis suggests these hefty creatures could hop - but only if they really needed to.
