In the three years since the James Webb Space Telescope sent back its first images, it's pulled back the veil on a whole bunch of mind-blowing cosmic phenomena. So how has this $13 billion bit of kit shaped what we know about the Universe — and what is yet to come?

We hear from scientists who push the boundaries of creation, whether that's building wild and wacky snack flavours (successfully) or cloning extinct tropical frogs (unsuccessfully … so far).  And since President Donald Trump retook office, the state of health and science research in the US has been precarious for many who work in those areas.  But there is a silver lining. Other countries such as Australia are implementing programs to recruit US researchers looking to relocate.

We often hear about places where the air quality is bad, even dangerous, but what about where the air is the cleanest on Earth? That air can be found blowing onto the north-west tip of Tasmania at Kennaook/Cape Grim, where an air pollution station has quietly been keeping track of how humans have changed the makeup of our atmosphere for 50 years. So what does the world's cleanest air tell us?

A couple of months ago, a killer started mobilising off the South Australian shore — one that would wipe out marine life, make surfers feel sick, and smother picturesque beaches in thick foam. The culprit? A bloom of tiny organisms called microalgae. We can't see them with the naked eye, but in big enough numbers, they can devastate ecosystems. So what made the South Australian algal bloom so lethal, and can anything be done about blooms like it?

People have been in the Australian wilderness for generations. But can people be considered part of the natural landscape or will they always have an impact?

If you were impressed by generative AI such as ChatGPT, then artificial general intelligence or AGI promises to really knock your socks off. Over the past couple of decades, tech companies have been racing to build AGI systems that can match or surpass human capabilities across a whole bunch of tasks. So will AGI save the world — or will it spell the beginning of the end for humanity?

She could only read and write from age 10. She reared children and had a first unsupportive husband. But Mary Somerville was able to correct the work of Isaac Newton, help discover Neptune, and write a science book which became a university text.

The next time you pick up a bag of spuds from the supermarket or fill up the car with petrol, you can thank the Treaty of the Metre for the metric system that underpins daily life. The treaty was signed exactly 150 years ago, when delegates from 17 countries gathered on a Parisian spring day to establish a new and standardised way of measuring the world around us. But the metre's inception predates the treaty that bears its name by nearly 100 years. So how did it come about, and how has its definition changed over the centuries?

Amateur fossil hunters make a major discovery. And Marilyn Renfree describes the sophisticated reproduction of marsupials.

Southern right whales (Eubalaena australis) were named by whalers because their high oil content made them the "right" ones to kill. In the decades since whaling was banned, southern right numbers increased — but a new study shows that population growth stalled, and might've dropped a bit, despite current numbers still far below what they were in pre-whaling times. So what's going on with the southern rights?

David Walker at UCLA says he can halt aging in fruit flies. Can the same concepts be applied to humans? And two tertiary students and an artist describe combining science and artistic pursuits.

Cobras, taipans, black mambas — Tim Friede's been intentionally bitten more than 200 times by some of the most venomous snakes on Earth. And he survived, mostly because years of self-injecting venom let him develop immunity to them. (Please do not try this yourself!) Now his blood's been used to make a broad-spectrum antivenom that researchers say may protect against nearly 20 deadly snakes. But this is not how antivenom is usually made. So how are snake antivenoms produced, and where are we with a "universal" version?

Mansi Kasliwal describes how she detects supernovae – the massive stellar explosions where elements are formed. We learn how dung beetles saved the Australian environment from the big problem, and David Attenborough shares his love for Birds-of-paradise.

Hate getting needles? You're in good company — one in five people in Australia have needle fear.

Sharks have survived 500 million years while mass extinctions have wiped out other species. Now, sharks are under threat.

Somewhere out past Mars in the early hours of Easter Monday, a space probe called Lucy whizzed by an asteroid named Donaldjohanson. Lucy then sent back images showing Donaldjohanson is about five kilometres wide and shaped like a peanut. It's one of a handful of asteroids on Lucy's 12-year itinerary. So what does the billion-dollar mission hope to achieve?

Palaeontology helps reveal why some animals are in desperate need of help while others thrive.

Gout Gout is fast becoming the face of Australian athletics, regularly clocking blisteringly quick times over 100- and 200-metre sprints. And he's only 17. Many think the best is yet to come. So what is it about Gout that makes him such an impressive sprinter at such a young age?

A protein in the immune system, DECTIN-1 - primarily responsible for defending the body against fungal infections, has been found to control the severity of autoimmune diseases such as irritable bowel disease (IBS), type 1 diabetes, eczema, and other chronic disorders.

We've been hearing a lot about a certain proposal to get nuclear power up and running in Australia, but little's been said about what happens when plants reach the end of their life. Decommissioning a single nuclear power plant can cost hundreds of millions of dollars and take decades. So what's involved, and why is the process so long and expensive?

Soils are too often neglected but caring for them brings many benefits for plant nutrition, human health and a boost for the farm economy.

Hearts, kidneys and now livers — over the past couple of years, surgeons have taken all these from gene-edited pigs and put them in people.
