The trials and tribulations of trees

It's 150 years since Darwin's theory of Evolution was presented to the Linnean Society, and so we've Naturally Selected the Science of Evolution! We find out why scientists have revisited a textbook example of natural selection in action, find out why horny sheep are gambling on good weather and how bacteria in the lab can evolve into a new species! We find out why tragedy almost kept Darwin's ideas from ever being seen, by looking at the archives of his own letters. Plus, why crocodiles chat from inside their eggs, a new way to send messages underwater and why Martian soil would be good... Like this podcast? Please help us by supporting the Naked Scientists

Mirrors, Magnets and Meteorites make an appearance in this week's Naked Scientists Question and Answer Show. We find out how the immune system could be convinced to fight skin cancer, how future MRI scans could be in colour, and why easy-clean computer keyboards could help keep MRSA out of hospitals. We answer your questions about inhaling helium, wind turbines, bacteria and the molecular basis of mirrors. Plus, in Kitchen Science Dave sets us the Balloon Kebab Challenge! Like this podcast?

Get Red Hot and Dirty with the Naked Scientists as we explore the science of volcanoes. We discover how the heat from hot rocks can be used to work out what gases are emerging, how likely a volcano is to erupt and whether it will go with a bang or a whimper. We also hear how hot runny rock can shatter under pressure to trigger an earthquake, and dip into the cooler, dirtier world of mud Volcanoes, like Lusi, which is currently pouring millions of gallons of mud onto the island of Java. Plus, we find out how a small date plant made history by being the oldest seed ever to germinate, why the... Like this podcast? Please help us by supporting the Naked Scientists

Ancient Greece is on the naked scientists' menu this week as we travel back in time to 1200 BC to discover how modern science and a 3000 year old poem have solved an ancient riddle. A team of classicists, geologists and archaeologists claim to have found the island of Ithaca, home of the legendary Greek hero Odysseus. Digging further into the past we also hear how geophysics can help archaeologists to see what lies buried underground but without having to lift a trowel. We also learn how dormant brain stem cells can be brought back to life, why it's not just size that is important when it... Like this podcast? Please help us by supporting the Naked Scientists

Footballs in space, mind-controlled machines and long-lasting bubbles join your questions on this week's Naked Scientists Question and Answer show. We discover the feminine side of prostate cancer and the robot that can walk up walls, and also hear how a computer has designed the next generation of mosquito repellents. Plus, we revisit the Phoenix mission on Mars, and also find out how surfing the internet can contribute more carbon to climate change than surfing the skies in an aeroplane! Plus, in Kitchen Science, Dave demonstrates a psychedelic effect with some milk. Like this podcast? Please help us by supporting the Naked Scientists

Hours before NASA's phoenix mission was due to land on Mars, the Naked Scientists took our own tour of the Martian landscape. We discuss how looking in valleys could tell us what shaped the Martian surface, and how probing Martian mud could reveal signs of life past and present. Also, we find out how scientists have watched the explosive death of a star, and how an asteroid collision millions of miles away could have seen the birth of the meteorite that killed off the dinosaurs. Plus, in Kitchen Science, we show you how to make weightless water! Like this podcast? Please help us by supporting the Naked Scientists

Come with us on a tour of your body to discover how the bacteria that live on and in you play an important role! Bad breath bacteria, good gut bugs and the ones that escape through the other end all make an appearance, as we find out how bacteria are essential to your health and how probiotics could prevent or even treat asthma and allergies. Plus, we find out how clot busting drugs could treat brain haemorrhages, why pilot whales are the cheetahs of the sea and how a robot could give you a full head of hair. Plus, in a smelly kitchen science we ask if coughs and sneezes can spread diseases,... Like this podcast? Please help us by supporting the Naked Scientists

Using nature's own tricks, we find out how to avoid mosquito bites, grow more crops and keep the weeds away in this week's Naked Scientists. We find out why mosquitoes prefer some people to others, and how to use pheromones to turn an insect's sex-drive against it! Also, why dentists could use plasma to cut down on drilling, why breast is best for bigger brains and why Popeye was right, spinach really does make you stronger. Plus, in Kitchen Science, we brave a box of biting mozzies to see if insect repellent really does repel! Like this podcast? Please help us by supporting the Naked Scientists
