A recent paper demonstrated that mice show elevated stress levels in the presence of male hormones. What implications does this have for future mouse research? Adam Rutherford heads to University College London to speak to Dr Clare Stanford, who works with mice and men.How do you get jet fuel from thin air? Just add water, carbon dioxide and a large amount of concentrated sunlight. A team from the European Solar Jet Project has, for the first time, proved that you can make 'green' or carbon neutral paraffin, the hydrocarbon used in jet fuel. It's feasible; the next step is to try and make this process commercially viable.Neuroscience is a fast growing and popular field, so naturally there are an abundance of stories reported in the press often illustrated with a beautiful picture of the brain. But despite the advances, when an area of the brain 'lights up" it does not tell us as much as we'd like about the inner workings of the mind. Adam Rutherford speaks to neuroscientists to get to the bottom of what brain imaging can be useful for and when over-interpretation is an issue.Our resident zoologist Dr Tim Cockerill recently found himself filming animals deep in the jungles of Borneo. Before he left, we gave him an audio recorder to see what he could discover about the animal communities there, just by listening to them. It seems you can set your watch by some of their calls.Producer: Marnie Chesterton.

Y Chromosome We learn from a young age that if a fertilised egg carries XX chromosomes it will be a girl, but with XY it will be a boy. This male Y sex chromosome has lost many genes along its evolution over the past 180 million years and now only about 20 genes remain. Now two new studies in Nature journal have given clues into how the Y chromosome evolved into its current state by looking at the genetic make up of 15 species the team built an archaeological record of all the mutations that occurred over time - to trace the timing of how the Y originated.... Professor Henrik Kaessmann from the University of Lausanne in Switzerland explains that the genes that remain play a more important role than previously believed.Everest Avalanche Last week the biggest single loss-of-life event occurred on Everest: a huge avalanche killed 16 Sherpa guides. All were so-called "icefall doctors", possibly the riskiest job of all, which involves finding a route through the broken mass of icefall, and then securing ladders and ropes for mountaineer tourists to follow. The Himalayan Sherpas have abandoned the climbing season out of respect for the fallen. There are many questions about health and safety, but we want to know what could be done to help? BBC Science Reporter Victoria Gill has been looking at the science behind avalanches, Are avalanches predictable? And will global warming in the Himalayan region make them more common? Aphid Survey This month the Rothamsted Research in Hertfordshire's Insect Survey will have been monitoring national aphid populations for fifty years. Aphids, such as greenfly and blackfly, can cause extensive damage to plants and crops. The aphid season - as many gardeners will know - is just about to start. But how has the recent mild, wet winter affected their numbers?Lichens An Inside Science listener emailed in to ask about lichens - what are they and how do they live. We called in plant ecologist Professor Howard Griffiths, at the University of Cambridge to fill us in on these hardy, pioneering organisms.Longitude 300 years ago there was no way of knowing the position of a ship out on the high seas. The greatest scientific challenge of the age was navigation. Britain's response was to offer a large prize fund for the solution to the problem of Longitude. Richard Dunn, curator and head of science and technology at Royal Museums Greenwich tells Marnie Chesterton the story of John Harrison, a clockmaker and carpenter, who solved this seemingly impossible problem.Producer: Fiona Roberts.

How sperm recognises the egg The discovery of a protein on mammalian sperm almost a decade ago, sparked the search for the corresponding receptor on the egg. Now researchers in the UK have found this receptor in mouse egg cells. They propose to call it Juno, after the Roman Goddess of fertility and marriage. The finding indicates that these two proteins need to interact for normal fertilisation to occur. And in humans, it could lead to early screening of couple to decide which appropriate fertility treatment they require.Dogs as clinical models Dogs play an important companion role in society, but man's best friend can suffer from hundreds of different diseases. Surprisingly, many of these are very similar to human diseases, including cancer and autoimmune conditions. Research into a range of naturally occurring canine conditions has the potential to lead to some ground-breaking medical advances and improve human health.Automatic Facebook Keeping up with your online social network of 'friends' on Facebook can sometimes be time consuming and arduous. Now artificial intelligence expert, Boris Galitsky, has invented a robot to do the bulk of his social interactions online. But how realistic is it? And does it fool his cyber pals?Artistic brains feedback Last week we ran an item showing that researchers have found that artists' brains were structurally different from those of non-artists. This sparked a lot of listener feedback and debate on what is the difference between being an artist and being creative? Is it nature or nurture, or both? We attempt to get your points across!Invasive Alien Species The European Parliament has approved new legislation which hopes to contain the spread of invasive species of plants and animals in Europe. It has proposed bans on the possession, transport, selling or growing of restricted species. The list, which includes plants like Japanese knotweed and Himalayan balsam and animals like the "killer" shrimp, which can wreak havoc when they spread, was restricted to just 50 species. But now it will be open-ended, so when new alien invasive species arise, they can be dealt with more easily. But in the UK, what constitutes an 'alien' species and how do you decide whether it's invasive? And what about all the 'alien' plants we already grow in our gardens?Producer: Fiona Roberts.
