A brain injury like a stroke or a neurodegenerative condition like Huntingdon or Parkinson’s disease can be a long and arduous ordeal. It can be difficult to diagnose and there are no clear treatments, but scientists are working hard to solve it. We find out about the important role Glial cells play in supporting neurons and how things can go wrong if they are disrupted. We also find out about ways to use the abundance of Glial cells to make new neurons. Plus we get a better understanding of cell death and repair and the roll proteins can play in slowing down those processes to give your brain time to recover.

Lagrange Point Episode 311 - Stellar deaths, black holes, white dwarf accomplices and crystal stars12/1/2019
What happens when a star dies? We can investigate what is left behind at the scene of the crime to piece together the final moments of a star. Some become white dwarfs so cold and cool they crystalise with thick oxygen and carbon skins. Others collapse in on themselves becoming supernova in a catastrophic core collapse. But sometimes in complex binary systems there is an accomplice that pushes the star over the edge, into supernova territory. Plus super massive black holes can devour passing stars, but sometimes they have a little help.
Lagrange Point Episode 309 - Fast Radio Bursts. Mysterious signals from outside our galaxy12/1/2019 Space is filled with incredibly strange objects, from black holes to neutron stars. In the right conditions these strange stellar objects create incredibly powerful radio bursts which give radio astronomers a treasure trove of data. From the WOW! Signal to Pulsars we recap the history of strange space signals, and we look at the modern hunt for Fast Radio Bursts (FRBs) and how the CHIME observatory in Canada is shedding light on this mystery.
Having a traumatic injury, serious infection or cancer is bad enough let alone if you have to have an amputation. But once that amputation has occurred how do you make life easier for the amputee? Prostheses are helpful, but they can require retraining your brain and lack the sense of touch. Plus phantom limb pain can make life painful and frustrating. This week we find out about surgical and biomedical treatments to help improve prostheses and give amputees better quality of life.
