Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

A beetle called the polyphagous shot-hole borer (Euwallacea fornicatus) is silently spreading through Perth and its surrounds, forcing councils to chop and chip hundreds of trees — even century-old Moreton Bay figs. So how does the tiny pest cause such massive problems?…

Play Later Play Later Lists Like LikedA 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?…

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?…

Play Later Play Later Lists Like LikedSouthern 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.

Play Later Play Later Lists Like LikedCobras, 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?…
