We talk to volcano scientist Ed Marshall in Iceland about working at the volcano which has burst into life spectacularly again after a year of quiet.    Also in the programme, we'll be following migrating moths across Europe in light aircraft to discover the remarkable secrets of their powers of navigation, and hearing how synthetic biology promises to create smarter and more adaptable genetically engineered crops.

Friday, April 13th 2029 – mark it in your calendar. That’s the day an asteroid the size of an aircraft carrier will fly past Earth, closer than some satellites. Don’t worry – it will miss, but it’ll will pass so close to Earth that it will be visible to the naked eye of 2 billion people, particularly in North Africa and Western Europe. Roland Pease this week attended the Apophis T-5 Years conference at the European Space Research and Technology Centre (ESTEC) in the Netherlands, meeting astronomers scrambling to get missions up to the object to learn what kind of threats such asteroids might pose to us in the future and to discuss the science of planetary defence.  NASA’s OSIRIS-APEX, a follow-on to OSIRIS-REx, will study the physical changes due to the gravitational forces from the Earth as it closely passes us by. But will there be an armada of spacecraft sent to monitor Apophis? The European Space Agency hope to gather support for their own mission, RAMSES. Presenter: Roland Pease

An armada for asteroid Apophis?

A black hole just discovered in our Milky Way galaxy, weighing 33 times the mass of the Sun, and dating back to near the time of the Big Bang, gives new clues to the origins of this dark astronomical mysteries. And dancing with a Sun-like star in our galactic neighbourhood, it offers a great opportunity for astronomers to take a detailed look in coming years, as astronomer Professor Gerry Gilmore of Cambridge University tells the programme.   Presenter Roland Pease has headed to the lab of Professor Ludovic Orlando in Toulouse, France where they are extracting ancient DNA from horses as part of a project called “Horsepower” - to reveal how our prehistoric ancestors tamed and domesticated these powerful animals (long after cattle and sheep) and in the process helped shape the extraordinary history of the first states of China and Mongolia.   
  
And a deep look into the mechanisms of addiction – showing how drugs of abuse, such as cocaine, hijack the neuronal pathways that had evolved to drive our innate needs such as eating and drinking. Roland hears from psychiatrist Eric J. Nestler of the Friedman Brain Institute at Icahn School of Medicine at Mount Sinai in New York, how this could one day improve addiction treatments.

Unexpected black hole in our galaxy

The highly pathogenic strain of bird flu, H5N1, has arrived on the continent. Australian bird specialist Megan Dewar, from the Federation University of Australia, has led a mission aboard the research ship the Australis.   Science in Action remembers physicist Peter Higgs 60 years after his Nobel prize winning theory of the Higgs particle.   The unfolding scandal of manipulated data behind claims of incredible room-temperature superconductivity. Science writer Dan Garisto has seen the details in a Rochester University internal investigation.  And the alga – single-celled seaweed – with superpowers. As well as capturing carbon from CO2 in the atmosphere, like other plants, this one can directly capture nitrogen too, essential for life, but which few organisms can do for themselves. We hear from the marine scientist who has revealed this evolutionary trick.  Presenter: Roland Pease

Bird flu in Antarctica

A powerful earthquake hit Taiwan on Wednesday morning, but thanks to the country’s early warning system and engineering-preparedness, there was little destruction and few deaths. Seismologist Ross Stein, CEO of earthquake consultancy Temblor, Inc., shares his analysis. 
 
The highly pathogenic bird flu H5N1 has been detected in cattle in the US and in a cattle handler in Texas. To learn more about this special animal-to-human transmission, Roland speaks to virologist Richard Webby of St. Jude Children’s Research Hospital in Tennessee and Director of the World Health Organization Collaborating Center for Studies on the Ecology of Influenza in Animals. 
 
French Space Institute Supaero in Toulouse is collaborating with Japan’s space agency JAXA to send and land a rover on Phobos, one of Mars’ tiny moons. Roland travels to the University of Toulouse to learn more about building this wheeled Rover from Supaero’s Naomi Murdoch.  Transitioning to a clean energy future requires mining materials like rare earth minerals, but how will this impact our environment? Jessi Junker of the ecology charity ReWild explains her research and concerns for great apes as mining for these materials expands in Africa.   Presenter: Roland Pease

Earthquake in Taiwan

3000 light years from Earth, a white dwarf star called T Coronae Borealis is on the brink of a “once-in-a-lifetime” explosion.  Astrophysicist Bradley Schaefer is enthusiastic about the bright star set to appear in the night sky in the coming months.  Professor Irving Weissman has been researching ways to restore youth using mouse models for decades. He has sewn old and young mice together to join their circulatory systems and has found that giving old mice blood from younger mice reverses some signs of ageing. In his group’s paper, the use of an antibody-based therapy has been shown to restore a declining immune system in ageing mice. Not quite the fountain of youth but potentially a key step in halting many age-related diseases. Roland gets the details from Irving and first-author Dr Jason Ross.  And, in the small town of Cabrières in Southern France, producer Ella Hubber goes on the hunt for some 480-million-year-old fossils with part-time fossil prospectors Eric and Sylvie Monceret. Their latest excavation site is a gold mine of rare, soft-bodied fossils from the period during a time when this part of France was underwater. And at the South Pole.   Presenter: Roland Pease
