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?…

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?…

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?…

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?…

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.
