When you were little did you ever dream of becoming an astronaut? Well Michael Foale did and he actually made it happen. Born in the UK Foale completed both his undergraduate and doctorate degrees in Cambridge before joining NASA and going on to become the most experienced UK-born astronaut. Well he was back in Cambridge to talk about his experiences at a Pint of Science event and Connie Orbach went along to find out how a UK lad got to be a NASA astronaut... Like this podcast?

Quantum mechanics describes the properties of light, atoms and the even smaller particles inside atoms, like electrons and protons. On these tiny scales, we observe strange effects that contradict our everyday experience and we are beginning to harness these effects to build technologies that seemed impossible before. Kerstin Gpfrich went to the 2016 National Quantum Technologies Showcase in London to find out about the latest quantum leaps in quantum technology. Like this podcast?

Compared to a lot of the objects in our solar system the Earth's Moon is a bit unusual. A new theory, published in the journal Nature, explains how the Moon got to where it is today. Professor David Rothery, from the Open University, wasn't on the paper but he took Liam through what Matja Cuk, the study's lead author had done. He started by explaining what makes the Moon such a space oddity... Like this podcast? Please help us by supporting the Naked Scientists

Plants can be good for the planet, nice to look at and often pretty tasty. But what if they were also high tech sensors that we could harness to detect harmful chemicals and even explosives in groundwater or the air around them? Michael Strano and his group from MIT have produced just such a "bionic" plant by engineering spinach plants to produce more, or less, infrared light in the presence of certain chemicals. Connie Orbach heard how... Like this podcast? Please help us by supporting the Naked Scientists

The Paris agreement is an international climate change treaty signed earlier this year by 192 countries and it aims to mitigate man-made global warming. It kicks in from this week. But will its targets be sufficient? Over half of the Arctic sea ice area has been lost in the past 40 years and we may yet lose all of it. That's according to a new study from the Max Plank Institute for Metrology in Hamburg. Kerstin Gpfrich spoke to study's author Dirk Notz. Like this podcast?

Conditions like Down's Syndrome, which are caused by babies carrying the wrong numbers of chromosomes in their cells, affect about one pregnancy in every 500. There are also many other inherited disorders that run in families but can't be diagnosed without a sample of the developing baby's DNA to test. But obtaining that DNA is risky; pregnant women have to undergo tests like an amniocentesis, where a needle is used to obtain cells from around the baby. When doctors do this, there can be up to a one per cent risk that the woman will have a miscarriage. These tests also cannot be performed... Like this podcast?

White lies are widely accepted as an integral part of our everyday lives. And yet history has taught us how a series of small transgressions can snowball with detrimental outcomes. But can we really get desensitised to lying, and if so, what happens in our brains? Tali Sharot from University College London answered this question in her new study and Kerstin Gpfrich wanted to know more about it... Like this podcast?

When most people think of dinosaurs they'll likely conjure up images of the stabbing teeth of the T-rex or the cutting claws of a Velociraptor but what about the squishy bits of dinosaurs? To find out more Liam Messin went to the University of Cambridge's Earth Science Department to speak with Dr Alex Liu. Alex was co-author of a recent study detailing a fossilised dinosaur brain. Liam started by asking Alex precisely what he and his colleagues have described in the paper Like this podcast? Please help us by supporting the Naked Scientists

According to the Office for National Statistics, the ONS, in England and Wales deaths involving heroin and morphine have more than double since 2012. The ONS say this is partially driven by a rise in heroin purity and availability over the last three years. Age, they say, is also a factor because heroin users are getting older and they often have other conditions, such as lung disease and hepatitis that make them particularly vulnerable. But are these the only reasons? John Middleton, president of the UK's faculty of public health, in an editorial in this week's British Medical Journal,... Like this podcast?

We all know that men aren't really from Mars and women aren't really from Venus, we are both from Earth and there are more similarities between sexes and genders than there are differences. But, even after many decades of campaigning there are still issues with gender equality across many areas of life from equal pay for equal work to shared parental leave or even just differences in ways of working. One topic that's really important to us here at the Naked Scientists is the balance of men and women in STEM research, that's Science, Technology, Engineering and Maths, so to delve into this a...

On the 13th of October Addenbrooke's hospital in Cambridge turned 250 years old. As an established teaching hospital, it trains hundreds of medical students with the final three years their time spent on clinical placements. Connie Orbach went to meet up with some of these students to hear how they're getting on. Starting with 4th year Keerthi Senthil who Connie grabbed on his lunch break, only weeks into his first placement on the wards... Like this podcast? Please help us by supporting the Naked Scientists

Over 35 million people worldwide are living with HIV. Treatments cost billions and don't come without significant side effects for the individual. Now, researchers from Emroy University may have found a new drug duo to eliminate the need for debilitating lifelong HIV treatments.

Levels in the atmosphere of the greenhouse gas methane released accidentally by the oil and gas industry might be up to 60% higher than climate scientists had budgeted for. A new method combining long term atmospheric measurements of methane levels with a way of fingerprinting where the gas has come from has enabled scientists at the University of Colorado to make more accurate predictions of the status quo. Grant Allen is an atmospheric scientist at the University of Manchester and wrote a commentary on the new study for the journal Nature, where it's been published this week. Chris Smith...

What makes dogs man's - or woman's - best friend? Scientists in Sweden gave a pack of dogs an impossible task to do: pushing along a plate that was actually stuck to the floor. The dogs that sought help from their owners were set up a different way genetically from dogs that like to be more wolf-like and independent. Georgia Mills spoke to researcher Per Jensen to hear what he's sniffed out... Like this podcast? Please help us by supporting the Naked Scientists

There is a centuries old debate about violence between people - is it something we're born with, or a product of our environment? Understanding the causes of violence is important if we want to try and reduce it, and so there have been hundreds of social experiments trying to establish this. But this week, some scientists have taken a different approach, and looked across all mammals for answers, and found that throughout human ancestry, we have been becoming progressively more violent. Laura Brooks spoke to Professor Mark Pagel of the University of Reading, who had been looking into the... Like this podcast? Please help us by supporting the Naked Scientists

Since the 1970s scientists have condemned fats - or lipids - as the culprits that cause heart attacks. But while that's certainly true of some fats, it's not the case for all of them. Because one, called palmitoleic acid, can potently protect arteries against becoming clogged. When it's fed to mice it cuts their levels of arterial disease by over 30 per cent. Ebru Erbay, at Bilkent University in Turkey, is sufficiently impressed with the performance of palmitoleic acid on her mice that she now even eats it herself as she told Dr. Chris Smith.
