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.
Ichthyosaur found in Rutland
The astonishing discovery of this jurassic era creature has been covered on our show before, but this recording features special insight into the dig itself. Mark Evans from the British Antarctic Survey and Emily Swaby from The Open University describe the significance of finding the skeletal remains of this marine…
The Reforestation Re-evaluation
Tropical rainforests are deforested at an alarming rate to make way for cultivating crops and rearing livestock. But what happens when these forest areas are abandoned and left to recover in their natural way? Research published in the journal Science gives a message of hope, explaining how forests are able…
Sleep and Alzheimer's
Changing the way the brain controls how we sleep, as a new study suggests, might be a way to cut the risk of Alzheimer's Disease. Alzheimer's is the commonest form of a group of conditions known as senile dementia. They occur when brain cells are lost, progressively robbing us of…
Do Asteroids Pose a Real Threat?
Katie King interviews Huw James, from the Royal Astronomical Society, about the reality of the chances planet-killing asteroids could collide with Earth. What these objects are, how they are found, and what methods are being trialled to prevent any potential collisions... Like this podcast? Please help us by supporting the…
Listening vs hearing
Hearing and listening... is there a difference? I am sure that we have all been guilty of letting our minds drift out of a conversation before realising and immediately trying to tune back in. New research published in Cell Reports describes how brain activity varies during listening and hearing and…
Language and the Brain
Understanding the human brain and how it completes complex tasks, like processing other people's speech as well as producing its own, is a complex task in and of itself. As it stands, neuroscience isn't able to tell us the underlying computations that lead to human language. New research from the…
What is the impact of a black hole?
Astronomers believe that nearly every galaxy has a supermassive black hole at its centre, this being true for our very own Milky Way. These objects exert such strong gravitational forces on the matter contained within them that it cannot escape the black hole's pull. Scientists using the LOFAR telescope in…
IVF embryos are more successful than expected
During IVF or in-vitro fertilisation, sperm and eggs are mixed together in a dish to produce fertilised embryos, one or two of which are placed in the uterus where the hope is they will trigger a successful pregnancy. Previously, embryologists would pick out and use only what they judged to…
Making antibiotics more effective
While the coronavirus pandemic is at the forefront of our minds, it's not the only health crisis looming on the horizon. Antimicrobial resistance has been called the "hidden pandemic". One of the ways to counteract resistance is by developing drugs that make current antibiotics more effective, and new research published…
Omicron update: what's in store for Australia
Dr Chris Smith joins Indira Naidoo on the ABC's Nightlife programme to discuss the latest developments in science and answer questions from listeners. This time they look at the difficult decisions confronting politicians and policymakers internationally and how they should react to the omicron new variant, which appears super transmissible…
The recent evolution of human beings
Us humans are thought to have appeared on Earth around 300,000 years ago. But how much have we changed since then? New research from Shanghai Jiao Tong University has found many of our most complex traits have continued to be tweaked, even in the past two to three thousand years…
100 years of insulin
2021 marks 100 years since insulin was first discovered. The World Health Organisation estimates that 422 million people around the world have diabetes, a disease where the body either can't produce enough insulin or doesn't respond properly to insulin. In the UK, 1 in 15 people are affected, and that's…
Cooling down rapidly warming cities
More than 50% of the world's population now lives in urban areas and, in recent years, many major cities have been hit with extreme weather events due to the effects of climate change, like the flooding that hit the London underground - and Queen guitarist Brian May's basement - in…
Tree growth extended in urban jungles
Cities have been found to be warming at faster rates than the rest of the planet due to the materials used such as concrete absorbing heat more readily than organic materials. This is known as the "urban heat island" effect. One antidote, scientists have found, is to plant trees. But…
The science of hugs
As we near Christmas, we will be subjected to a fair few more hugs than usual! Some of them can be great, and others... just downright awkward. But what makes a bad hug? What makes a good hug? New research has been published investigating the most pleasant hugging style. Katie…
Sleep schedules & healthier hearts
We know that sleep is critical for our physical and mental wellbeing, but as it turns out, the answer doesn't simply lie in the number of hours we spend unconscious each night. New research from digital healthcare company, Huma, suggests that a goldilocks bedtime between 10-11PM is linked with a…
Omicron, variant of concern. What do we know?
Virologist Chris Smith talks with Radio New Zealand National's Kim Hill on Saturday 27th November as the world contemplates the discovery of the Covid-19 variant that the WHO has dubbed "Omicron" and labelled as a "variant of concern". How will scientists investigate this agent, and how are policymakers responding? Will…
Whales eat (and poop) more than we thought
Earth's largest animals, whales, need a lot of food... that goes without saying. But, new research from a team at Stanford University have found that whales need 10-20 tonnes of food on a feeding day, which is up to three times more than initially thought. Of course that means three…
NASA's planetary defence test
Now this might have flown under your radar, but last Wednesday NASA launched the DART mission, a spacecraft on a one-way collision course with an asteroid, in the world's first full-scale planetary defence test. Tricia Smith asked Space Author Colin Stuart, if life as we know it is in danger…
Covid Surges in Europe
Covid cases in many European countries are suddenly substantially up. But in a dramatic role reversal, the UK has gone from the standout Covid-19 bad boy of Europe to one of the better performers in terms of daily cases and hospitalisations. According to the London School of Hygiene and Tropical…
