Tiny robots in your blood? The possibilities of nanotechnology

Some things are so tiny you can't see them under a normal microscope – think proteins and molecules. These are a thousandth of the size of the red blood cells running through your veins. We measure these things in nanometres where one nanometre is a billionth of a metre. Scientists have some adventurous ideas harnessing things at the nanoscale - a field called nanotechnology. Some ideas are realistic, others are still science fiction. Dr Sophie Calabretto talks to Cosmos Magazine journalist Ellen Phiddian about nanotechnology, what's realistically possible and how on Earth you work with things this small.

You're shedding your DNA everywhere you go

Ancestry.com, hair samples and crime scenes - that's likely what you think of when you hear DNA. Probably not fish mucus and kangaroo scat. That's what's called environmental DNA - or eDNA - and ecologists can track it down pretty easily to find out what animals and organisms have been where. But some are concerned about human eDNA could be collected and used in nefarious. Dr Sophie Calabretto talks to Cosmos Magazine journalist Ellen Phiddian about the good and the bad uses of environmental DNA.

Antarctic ice is melting five times faster than we thought

We’ve modelled the ice melting in Antarctica for decades, but new research suggests it’s melting five times faster than we previously thought. The biggest concern is that more melting ice means higher sea level rise, but that’s far from the only thing we should be worried about. Dr Sophie Calabretto talks to Cosmos Magazine journalist Matthew Ward Agius about what’s going on with Antarctica and putting a plug in sea level rise before it gets worse.

Masses of people online claimed to remember events or images as being one way, when they’re actually completely different to how they recall them. False memories have mostly been thought of as chance or a result of believing some conspiracy, however researchers are now trying to see if there’s a scientific explanation at play here.

Demystifying Forensics part 4: Unreliable forensic science has sentenced innocent people to death

There are HEAPS of other forensic methods we haven’t been able to cover in this series. And unfortunately, a whole bunch of them are nowhere near as reliable as you might think. At times, they can be flat out inaccurate. Dr Sophie Calabretto talks to Cosmos Magazine journalist Jacinta Bowler about the unreliable forensic methods, how some have sent the wrong people to jail and even sentenced innocent people to death.

What do astronauts eat in space?

Sitting down for dinner isn't so easy when you're floating around a spacecraft. Not only is dining quite different in space but the food options for astronauts are much more limited. Meals mostly come in tins, vacuum packs or protein pastes in squidgy tubes - but these can get boring fast, so researchers are brainstorming other options to keep astronauts and their tummies happy. Dr Sophie Calabretto talks to Cosmos Magazine journalist Evrim Yazgin about space food and how long until we can start growing food in space.

A lot of people are freaked out by spiders – no explanation needed – but fear often breeds contempt and spiders get an especially bad rap. Misinformation about spiders – or spider ‘fake news’ - spreads like wildfire online. So how much of what we read about our crawly friends is actually true? Dr Sophie Calabretto talks to Cosmos Magazine journalist Jacinta Bowler about where spider misinformation comes from and how many news stories are spun like a web of lies.

A covid update: what do we know about the new subvariants?

The relaxing of rules around mask-wearing, venue sign-ins and vaccination requirements has got a lot of people thinking we’re out of the woods when it comes to covid. But the arrival of new covid subvariants shows that's not the case. Dubbed the ‘scrabble’ variants - named after high scoring letters from the boardgame like B, Q and X - they’re spreading fast across Europe, Asia, the US and have now landed on Australian shores. Cosmos Magazine journalist Matthew Agius gives Dr Sophie Calabretto a covid update and looks at whether Australia is equipped to deal with another potential outbreak.

Putting the mystery drug to the pill test

A mysterious substance was brought to a pill testing clinic in Canberra, and they couldn’t figure out what it was. Pill testing is for people who choose to take illegal drugs and want a better idea of what they’re taking, but it’s not always easy to figure that out. Dr Sophie Calabretto talks to Cosmos Magazine journalist Ellen Phiddian about where this mystery substance could have come from and the lengthy chemical processes to uncover what it is.

Malaria: how far away are we from global eradication?

In many parts of the world, a mosquito bite can be deadly, as it could be carrying malaria. But mosquitoes are just vessels, it’s actually an infectious parasite that’s at the root of transmitting the disease to humans. While treatments and prevention programs have eradicated the disease in many countries around the world, malaria is still an incredibly scary reality for many. Dr Sophie Calabretto talks to Cosmos Magazine journalist Jacinta Bowler about the defences we have against malaria and whether or not we can globally eradicate the disease.

Stumbling over dinosaur fossils in outback Queensland

How many more fossils are we yet to discover? You might not be aware, but there’s a stretch of land in outback Queensland that’s a hotspot for some really old dinosaur remains. And it’s keeping paleontologists busy! Every living thing that’s ever existed could leave a fossil and advances in technology mean we’re starting to discover a whole lot more of them. Dr Sophie Calabretto talks to Cosmos Magazine journalist Evrim Yazgin about uncovering fossils in 2022 and the farmers, to this day, stumbling over dinosaur bones in outback Australia.

Renewable energy certificates: why they are falling short

Planet Earth could be 2.7 degrees warmer by the end of the century according to some estimates. This is leagues above the globally agreed Paris target of well below 2 degrees Celsius or preferably 1.5. Many big emitters are saying we can reach this target through something called renewable energy certificates, but recent research has found these certificates have low integrity across the board. Dr Sophie Calabretto talks to Cosmos Magazine journalist Ellen Phiddian how renewable energy certificates work and why in some cases they aren’t reducing emissions at all.
