Special Editions
Probing the weird, wacky and spectacular, the Naked Scientists Special Editions are special one-off scientific reports, investigations and interviews on cutting-edge topics by the Naked Scientists team.
Boaty McBoatface and the Antarctic mystery
In March 2016 the public voted to name a new polar research vessel "Boaty McBoatface", ultimately though, it was decided that "RRS Sir David Attenborough" was a more fitting choice. But the name "Boaty McBoatface" lived on and was instead given to one of the ship's autonomous submarine vehicles. Now,…
Smarter, safer robots
Robots are increasingly used to take over repetitive tasks in industry and agriculture, but they are still limited in what they can do. This also means that humans still need to work alongside them and often things can go badly wrong. 13000 injuries and 60 deaths were caused by accidents…
Fish: a small world after all
The world is facing a global fish issue - a fissue, if you will. One third of all fish stocks are being overfished, and most of the efforts to prevent this involve exclusive zones in the ocean managed by individual countries. But a study released this week shows how the…
Asthma: mapping the human lung
The chest disease asthma is becoming more common. It can lead to life-threatening breathing difficulties when the airways constrict and the lung tissue overproduces mucus; this is usually an allergic reaction that can be worsened by air pollution. But our understanding of what's going on in an asthmatic lung is…
Cracking the secret of Antarctic ice holes
Holes in the Antarctic sea ice have been forming for decades, and are a mystery to science For information regarding your data privacy, visit acast.com/privacy
A special skill?
When it comes to understanding how the brain functions, scientists have done a great deal of work on studying macaque monkeys, our evolutionary relative. We share 93% of our DNA and in a lot of ways, our brains are very similar. Even for high level operations such as learning, memory…
Recyclable crisp packets using nanotechnology
At the end of 2018, Walkers launched their own recycling scheme for crisp packets after more than 300,000 people signed an online petition demanding that they change to a fully recyclable material for their packaging. Crisp packets are made from plastic and coated with a thin layer of metal. The…
CRISPR cuts life expectancy in twins
CRISPR stands for clustered regularly interspaced short palindromic repeats. Long name, but easy to picture: the sequence is synonymous to a word processor for a book, the book being DNA, which allows scientists to not only read the book, but to also edit a specific 'passage' of the book. Using…
How to mend a broken heart
Around 1.4 million people alive in the UK today have survived a heart attack, but survivors can suffer from debilitating heart failure, because the heart is damaged during the attack. Ten years ago The Naked Scientists spoke to Sian Harding from Imperial College London about some promising new "heart patches"…
An antibiotic made from metal
Antibiotic resistance occurs when bacteria evolve to sidestep the drugs we use to kill them. With resistance rising, we could be facing an "antibiotic apocalypse", where even trivial infections become untreatable. What's worse, almost no new antibiotics are being developed by the major pharmaceutical companies. Now, though, Kirsty Smitten has…
Sensing air pollution
To better understand how personal exposure to air pollution can impact an individual's health, Katie Haylor met up with Cambridge University chemist Lia Chatzidiakou for a walk around central Cambridge. And to find out how air pollution can be monitored across a whole city, Katie climbed up to the roof…
Bacteria not slowed by obstacles
Researchers have gained new insights into how bacteria move in complex environments. Bacteria move using a system called "swim-and-tumble": they swim in a straight line for a bit, then tumble in a circle, which gives them a chance to correct their course. They can't see where they're going - they…
Hiroshima buildings found in beach sand
Geologists from the University of California, Berkeley, found something unexpected in sand samples from Japan. Rather than natural particles, from rocks or plants, these tiny blobs of glass seem to have been formed in an atomic blast, and they might mean that the destroyed buildings of Hiroshima have been hiding…
Reducing harassment online
Harassment in online communities is not a new phenomenon, but it is a growing one, with 40-46% of people reportedly having experienced it. Communities like reddit, one of the internet's, and the world's largest discussion forums, often have moderation teams responsible for applying self-imposed rules which govern acceptable behaviour. These…
Mystery of the miniature T-Rex
Everyone's heard of T-Rexes, the twenty-foot-tall monsters that roamed the Earth back in the Late Cretaceous Period. But you may not have heard of their miniature cousin. It's a six foot tall dinosaur called Suskityrannus hazelae, and it gives us a clue about when and how T-Rexes got as big…
Biodegradable bags might not biodegrade
Our society uses - and then throws away - a vast amount of plastic, which then accumulates in the environment. To combat this, in recent years, new types of plastic bags have become available, labelled as "compostable" or "biodegradable."Both of these terms indicate the bag can break down and so…
Caster Semenya and testosterone limits
Caster Semenya, a South African athlete with unusually high testosterone for a woman, has lost her appeal against new regulations from the International Association of Athletics Federations. The regulations set an upper limit on how much testosterone a female athlete is allowed to have compete in middle distance running, and…
DNA unveils origins of farming in Britain
Before Britain was a nation of shopkeepers we were a nation of farmers; before that, the population were a bunch of hunter gatherers. But farming didn't catch on here until 1000 years after it had in Europe. Why was always a mystery, but now DNA technology is shedding new light…
Premature labour: understanding the mechanics
Human babies grow inside their mothers for 40 weeks enclosed in a watery bag that expands as they do. And as the clock ticks during pregnancy, various processes kick in to thin the membrane material that surrounds the baby so that the bag ruptures at the right time to promote…
AI predicting battery performance
Batteries are in almost everything we use. Our phones, computers, energy storage, even in transport. Typically, to see how well a battery performs, scientists have to charge and discharge them over and over until, ultimately, the battery stops working. This can take years of development and testing, plus it's an…
