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?

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?

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?

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?

As far as planets go, they don't get much more iconic than Saturn. A huge golden ball encircled by gigantic rings. But those distinctive rings — the very things that give Saturn its pizzazz — have seemingly disappeared.
So what’s going on, and when will they be back?

Lord Howe Island may appear an island paradise, but its ecology has been under intense pressure from invasive species such as rats and pigs. Now birds are being found with stomachs full of plastic.

They might be the epitome of cool, but Formula 1 race car drivers can get hot — really hot.
An F1 cockpit can heat up to 60 degrees Celsius, and this affects cognition — the last thing you want when you're fanging around a track at 300kph.
This year, a new rule was introduced to give F1 drivers a bit of relief from that heat … which is just one of the risks of F1 racing.
Because we often hear about the performance of the cars in the race, but what about the humans behind the wheel?

80% of diseases are impacted by environment or lifestyle described as your exposome. Thomas Hartung expects information from studying the exposome will bring benefits on par with those brought by studying the human genome.

For women who get bacterial vaginosis or BV, a common condition that can cause a fishy-smelling discharge, many will get it again (and again).
Why some people were prone to recurrent BV was a mystery … until now.
Australian researchers have shown that BV-related bugs can be sexually transmitted, and treating male partners significantly cuts recurrence rates.

A weekly injection that stops that hankering for hot chips and donuts?
Many people on Ozempic and similar medications report this phenomenon, saying they no longer have incessant thoughts about sweets and fried food.
So how do these drugs, known as GLP-1 agonists, work in the brain to dial down "food noise" and help people lose weight?
