A woolly story about resurrecting mammoths raises serious questions for medical ethics. News of a scientist's plan to resurrect mammoths has spread around the world. However the story is largely untrue. We look at how this kind of 'fake science news' story can impact on perceptions of real medical research - some times with negative consequences. Almost all Europeans and Asians carry Neanderthal genes. Until recently these were thought to have little impact on us today, but new research shows they may be involved with determining height and aspects of both our physical and mental health. And what were Lennon and McCartney really thinking when they wrote their hit songs? Thanks to the number crunching power of computer algorithms the emotional content of 23 years worth of their compositions have been analysed. The results are both startling and for Beatles fans perhaps a little unsurprising.

Testing cyber security with science. The UK now has a new National Cyber Security Centre. However there is very little scientific evidence against which to test the detection of cyber attacks and effectiveness of measures to prevent them. We ask what is needed to turn cyber security into a more scientific discipline.Winston Churchill and Aliens. Throughout his life Churchill maintained a strong interest in scientific developments and wrote widely on subjects from quantum mechanics to nuclear energy. Newly discovered papers show he also had an interest in the potential for life on other planets.Dinosaurs and egg laying. A new fossil find revealing a dinosaur with an unborn baby suggests live births may have occurred many years earlier than previously thought. Turn off at level crossings. New research suggests personal messages about the impact of engine fumes on health may be the most effective way of persuading drivers to switch off their engines at level crossings.

Quantifying the impact of humanity on the earth's natural systems. Why human activity now has a larger effect on our planet than the forces of nature. We look at how mathematical equations can now be used to compare historical natural processes with contemporary man made changes. And we ask where current developments will take us in years to come.The Queen Elizabeth Prize for Engineering has been awarded to the inventors of digital imaging sensors. First invented in the 1970's, many of us use this technology everyday. These sensor can be found inside every digital camera ever made, from the devices used on space probes to collect distant images from the far reaches of the universe to the ubiquitous pocket cameras in our mobile phones.The earth is surrounded by junk - space junk. Many thousand of pieces of junk orbit the planet, left over from the history of everything we've ever sent into space. A new project has given a voice to this junk, and created a machine which plays simulated sounds of the junk as it passes overhead.Producer: Julian SiddlePresenter: Gareth Mitchell
