Hello, and welcome to the #bioscinews round-up! This is the place where you can find all the important biosci new stories from the past week, in a short, digestible paragraph.

This week’s news

In a rare find, palaeontologists in Scotland have stumble upon some sauropod footprints. The area where the footprints were found is thought to have been a lagoon in the Middle Jurassic – another dinosaur footprint was found in the area also. This marks the largest discovery of dinosaur footprints in Scotland, and adds to what we already know about Sauropods.

Malaria can be a large problem in certain areas of the world, and it is likely to spread with global warming, so control methods will be vital in the future. Since it is spread by specific mosquitoes, many strategies are aimed at reducing mosquito populations in malaria-prone areas. CRISPR (a new, promising gene-editing technology, and a technology which has been in our news quite a lot recently) has been used for the first time to cause heritable sterility in female mosquitoes. The technique was more than 90% effective, and models indicate that it would be a possible strategy to control wild populations of mosquitoes.

Turning differentiated cells back into stem cells is possible in some cases, but some problems still remain. It has not been possible to return all cell-types back to the pluripotent stage (a cell capable to turn into any other cell-type), but recent findings about epigenetic mechanisms may pave the way for improvements in this area. A central pathway in chromatin remodelling can be manipulated in order to return more cells to this “ground state”. Hopefully this advance will be useful not only in research, but also in regenerative medicine.

Easier pluripotent stem cells-

We hope you enjoyed this week’s news round-up, thanks for reading!
