It's been 8 years since the Large Hadron Collider went online and started smashing protons together at just below the speed of light. CERN announced this week that they're ready for a massive upgrade, and on Friday last week, there was a ceremony to break ground on what is being called the High luminosity LHC. Particle physicist Jon Butterworth from UCL discusses the next generation of particle accelerators that are undergoing early trials and what the newly announced upgrade means for particle physics.

Medical surgeons routinely stitch or pin organs and blood vessels with needle and thread and secure medical devices like pacemakers with hooks. But what if you could just use glue? Material scientist Terry Steele from Nanyang Technological University in Singapore has devised Voltaglue, a flexible adhesive that works in wet environments by putting an electric current across an inert substance. He explains how this new kind of chemistry could revolutionise many medical procedures.

This weekend Sir David Attenborough will reopen The Museum of Zoology at Cambridge University. It's undergone a five-year redevelopment, showcasing thousands of incredible specimens from across the animal kingdom, and exploring stories of conservation, extinction, survival, evolution and discovery. Adam Rutherford visits the new displays under the watchful eye of conservator Natalie Jones and zoologist and museum manager Jack Ashby.

And Professor Tim Birkhead of the University of Sheffield discusses The Wonderful Mr Willughby - his fascinating new account of 17th century ornithologist Francis Willughby who together with the celebrated naturalist John Ray pioneered the way we think about birds in science.
