ExpeRimental; Rosetta; MOOCs

ExpeRimental There's an online wealth of science demonstrations you can try at home with your kids. But what's sometimes lacking is the encouragement of questioning the science in these DIY experiments. Science teacher and film maker Alom Shaha has devised a series of videos with the Royal Institution showing parents experimenting with home-made lava lamps, bubbles and bottle cannons. He hopes that amidst the mess and mistakes, some scientific thinking can be nurtured.

Rosetta The European Space Agency's robotic spacecraft Rosetta is about to start its detailed study of the comet Churyumov-Gerasimenko. In the audacious and risky mission, the craft will follow the orbit of the comet as it approaches and passes the Sun. It will attempt to land a probe on the surface of the icy, rocky mass. It's hoped the mission will provide great insight into what comets are made of, how they behave as they heat up, creating its gassy coma and tail. And it's hoped Rosetta and its lander will be able to tell about where Earth's water and even some of the building blocks for life might have come from.

MOOCs Massive Open Online Courses are free and open to anyone with access to the internet. You can study a huge range of topics from cancer and dental photography to quantum physics, and even the archaeology and history of Hadrian's Wall. Critics say these higher education courses are just a PR exercise by universities, and that it will set up a two tier system in education. But Kathryn Skelton from FutureLearn, a platform for many of these MOOCs, argues that they encourage people who would not normally extend their education to take part and the universities providing the courses can gain great insight into the changing face of teaching methods.

Evolutionary Psychology Last week Adam Rutherford and Alice Roberts had a robust discussion on the biologising of the human condition, with Professor David Canter. Listeners wrote in to complain that we didn't give an evolutionary psychologist a right to reply, so this week, listener and evolutionary psychologist Rob Burriss has his say.

Pluto images, Space elevator, Insect migration, Imagination app

This summer, the spaceship New Horizons sped past Pluto at 30,000mph, snapping photographs as it went. The pictures sent back this week have transformed our view of this former planet. It isn't a dead rock; it is geologically active, with ice volcanoes and plenty of terrestrial movement. Dr Cathy Olkin from the mission explains what has got her team so excited.The space elevator, first dreamt up in the 19th century, is a tower tall enough to reach space. The sci-fi concept took a step towards reality recently, when the Canadian engineering company Thoth were granted a patent for an inflatable tower 20 kilometres high. Adam speaks to Thoth's Chief Engineer Ben Quine about the viability and possibilities of this project.It's the season when 30 million European songbirds fly south for the winter. Lower profile and harder to study are the billions of insects that take a similar journey. Dr Jason Chapman from Rothamsted Research tells Adam how to study animals that are too small to tagCan you measure imagination? A team from the Hungry Mind Lab at Goldsmiths University in London thinks you can. The goal of their two year project is to produce an app that can improve imagination by training it. To improve it, first they need to reliably measure it. Adam tries out their new test.

Homo Naledi, New spacesuit, Quantum biology, A possible cure for motion sickness

Tracey Logan talks to Professor Chris Stringer about the discovery a new human ancestor, Homo Naledi. With ape and human like features its age isn't known yet but could it be evidence of the origin of the genus homo? Astronauts' spines can elongate as much as 7 centimetres in space because of the loss of gravity potentially causing severe back problems. Tracey talks to David Green from Kings College, London about a new elastic suit he has helped develop to mimic the effects of gravity. What exactly is quantum biology? Marnie Chesterton talks to Jim Al Khalili and Johnjoe McFadden authors of 'Life on the Edge, The coming of age of Quantum Biology which is short-listed for the Royal Society Winton Book prize. Tracey meets Dr Qadeer Arshad at Charing Cross hospital to try a new potential cure for sea sickness. By applying an electric current to the scalp is it possible to prevent the symptoms of nausea? A limited number of tickets for Write on Kew are available by emailing writeonkew@kew.org with BBC Inside Science in the subject line.

El Nino, Sphagnum moss and peatlands, Inside Cern, Measuring air pollution with iPhones

Tracey Logan investigates the latest science news. Roland Pease reports on recent warnings that we're heading for one of the most severe El Ninos on record which could distort weather patterns around the world. Spongey sphagnum moss provides a protective layer to peat lands but in the bogs of the Peak District industrial and urban air pollution has killed nearly all the moss. This means the peat lands can erode releasing tonnes of ancient carbon. Tracey talks to horticultural ecologist, Neal Wright about his technique for creating tiny gel beads of sphagnum moss to spray on the moors to help restore their peat lands back to health. Marnie Chesterton talks to John Butterworth about his book, 'Smashing Physics' which is another short-listed entry for the Royal Society Winton book prize. He talks about the highs and lows of the discovery of the Higgs Boson and why CERN might soon be creating dark matter. Tracey talks to Toby Shannon, from the Institute of Physics about the International Year of Light citizen science project to measure air pollution using an iPhone.

Why the expansion of the paleolithic brain was powered by cooked carbohydrates. Gareth Mitchell talks to Professor of Evolutionary Genetics, Mark Thomas, about the difficulties of establishing what our ancestors ate. More than half the world's corals grow in deep, cold waters, many around the shores of the British Isles. But a new study shows they are under severe threat from ocean acidification caused by increased levels of carbon dioxide. Gareth talks to Professor of Marine Biology, Murray Roberts, from Heriot Watt University about why these corals could all be gone by the end of the 21st century. This week's short-listed Royal Society Winton Prize book is Life's Greatest Secret: The Race to Crack the Genetic Code. Marnie Chesterton talks to the author Matthew Cobb. BBC Science and environment reporter, Jonathan Webb, joins Gareth from the American Chemical Society meeting in Boston to talk about why the grime on buildings could be a new source of air pollution and why carbon dioxide in the atmosphere could be used to make carbon fibres.

Scottish GM ban, Earth's magnetic field, OCD, Birth of a new galaxy

As Scotland announces it ban on GM crops and with the current post of chief scientific adviser for Scotland vacant, Adam talks to the previous post holder, Professor Muffy Calder about the role of science advice to government and her reaction to news of the ban. The Earth's magnetic field is weakening which could be a sign that the magnetic poles are soon due to flip. Daniel Lathrop and team at Maryland University are trying to model the Earth's magnetic field using a large molten globe of sodium. Should we be worried if a flip is on the cards? Royal Society Winton book prize short-list: Science writer, David Adam, author of 'The Man Who Couldn't Stop' talks to Marnie Chesterton about his experience of Obsessive Compulsive Disorder. Adam hears about the birth of a new galaxy seen for the very first time. He talks to Chris Martin from Caltech about his latest galactic research published in Nature.

Pluto's surface, Increased Arctic ice in 2013, Linking brains together, Signals of fertility

The New Horizons probe is now millions of miles past Pluto, journeying throgh the Kuiper Belt, but still sending back gigabytes of data coming in via the Deep Space Network. Its latest image of Pluto's surface was released by NASA on Wednesday, of huge mountains emerging from an otherwise flat plain, Dr John Spencer one of the lead scientists on New Horizons, a planetary geologist, discusses what's to be read into the surface images captured over the last weekA new paper just published in Nature Geoscience shows that in 2013, which was a slightly cooler summer than average, arctic ice had grown, by 41% on the previous year. The study, uses data from ESA's Cryosat 2, which incorporates not just the surface area of ice, but the all-important number - the volume Adam examines the results with Rachel Tilling from University College London.Computing has taken a Sci fI step forward this month. Professor Miguel Nicollelis of Duke University, a specialist in brain machine interface experiments, has linked together the brains of four individual rats in order to use the computational power of their brains to carry out tasks including image processing, data retrieval, and even weather predictions. But could this have a therapeutic use in brain damage? Professor Andrew Jackson from Newcastle University, an expert in called 'neural prosthetics' examines the potential.Across the animal kingdom, signals advertising when females are at their most fertile can be pretty striking. Humans are more subtle, though plenty of studies have shown that female behaviour and physiology does change during the menstrual cycle. A new study by Dr Robert Burriss from Northumbria University suggests that faces may be advertising a woman's most fertile time of the month. But are the traits too subtle for most people to notice?Producer Adrian Washbourne.

Pluto: New Horizons

Pluto: New Horizons

It's billed as the last great encounter in planetary exploration. For the past nine years the New Horizons spacecraft has travelled 5bn km (3bn miles) to get to Pluto On July 14th it performed its historic fly-by encounter with the dwarf planet.Adam Rutherford examines the first images from the New Horizon's probe and hears the first interpretations from mission leaders and scientists at the NASA New Horizon's space centre as the data arrives back to earth. Expect new light to be shed on the Solar System's underworld as first impression s reveal Pluto to be a champagne coloured body with 11000 ft ice mountains and surprisingly smooth surfaces that suggests recent geological activityFor people who grew up with the idea that there were "nine planets", this is the moment they get to complete the set. Robotic probes have been to all the others, even the distant Uranus and Neptune. Pluto is the last of the "classical nine" to receive a visit. Dame Jocelyn Bell Burnell discusses how this 2,300km-wide ice-covered rock was demoted in 2006 to the status of mere "dwarf planet", but as "Pluto killer" Mike Brown argues, this shouldn't dull our enthusiasm.As Adam Rutherford reveals, nothing about this corner of the solar system has been straightforward. Little is known about Pluto's creation -but as the New Horizons probe passed Pluto for this first close up of the dwarf planet , scientists anticipate new insights into the evolution of our solar system and even earth's early history.With contributions from mission scientists Alan Stern, Fran Bagenell, Joel Parker and astronomer Mark Showalter. Updates too as interpretations rapidly develop, from BBC correspondent Jonathan Amos and astrophysicist Chris Lintott.Producer Adrian Washbourne.

Intrusive memories, Silent aircraft, Nuclear fusion, Pluto

Adam Rutherford talks to Emily Holmes from the Medical Research Council’s Cognition and Brain Sciences Unit in Cambridge, about two new studies on preventing intrusive memories. She discusses why stopping someone from sleeping after seeing a lab based film of traumatic events like a news reel or car crash may actually stop people from forming intrusive memories about those films. This offers an intriguing insight in to the role that sleep has in consolidating intrusive and possibly traumatic memories. She also explains how if memories of a traumatic event are laid down, why playing a computer game like Tetris could disrupt that memory and stop it from becoming intrusive. Silent Aircraft: The Davies report recently recommended a new, third runway should be built at Heathrow airport but as flight numbers increase how quiet can planes of the future become? Adam talks to Jeremy Astley from Southampton University and Michael Carley from Bath University about where the noise in jet engines comes from, how engineering can make them quieter and will the silent aircraft initiative ever make a truly silent aircraft.Nuclear Fusion. For decades scientists have tried to harness the power of the Sun to smash atomic nuclei together to create a clean, limitless energy source from nuclear fusion. Marnie Chesterton talks to scientists from Tokomak energy about their new design for a Tokomak machine that has already exceeded previous records. Could it be a vital step forward in the quest for nuclear fusion on Earth?New Horizons: On 14th July 2015 the spaceship, New Horizons will complete its 10 year mission to flyby Pluto. BBC Science correspondent Jonathan Amos gives Adam a preview and tells him why he's so excited about the mission and what they hope to discover about the darker regions of our Solar System.
