The UK science community draws vital benefits from EU membership and could lose influence in the event of an exit, says a House of Lords report out this week. UK researchers placed a high value on collaboration opportunities afforded by EU membership. A number also believe the UK would lose its ability to influence EU science policy in the event of leaving - something that's disputed by pro-Brexit campaigners. To debate the ins and outs of being in or out of the EU, Adam is joined by Viscount Matt Ridley, a member of the committee, and Professor Paul Boyle, the Vice Chancellor of Leicester University and former president of Science Europe.Scientists at Aarhus University in Denmark are developing a quantum computer. To help them solve a particular problem, they have turned to human brain power, harnessing our ability to play computer games. The team have designed video games, such as Quantum Moves - that are helping them to understand the problem of 'slosh'- that atoms move about, when moved, like water sloshing in a cup.Many diseases are caused by a particular type of DNA error called a 'point mutation'. In our genomes, the substitution of a single letter of genetic code can be the root cause of diseases such as Alzheimer's, sickle cell anaemia, and a whole range of cancers. Recently, a new technique for editing DNA, called CRISPR, a precise genetic engineering tool, was developed, which might help combat these diseases. The problem is that the cell often reacts to this editing; trying to mend what it perceives as damage to its DNA. This week, David Liu, from Harvard University, published new research showing how his team have managed to switch out a single letter, a base pair, whilst tricking the cell into not correcting this edit.
