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
Recently, the a fossil of a Ornithomimus dinosaur was found with preserved skin and feather structures, helping confirm the long-standing theory that some dinosaurs had feathers. The feather and skin patterns also help give insight into how these dinosaurs may have regulated their body temperatures.
Continuing with the fossil-related news, a new study proposed that limb-regeneration was ubiquitous in the ancestors of modern tetrapods. This means that this ability has likely been lost in most current tetrapod lineages. Keeping this evolutionary information in mind may lead to a better understanding of limb regeneration and why humans are not capable of this.
Antibiotic resistance is a problem in modern medicine, and one that threatens to undo all of the progress modern medicine has had regarding infectious disease. There are many different approaches to this problem, but a new approach harnessing currently used antibiotics and antibodies has proved very successful in rats, although it remains to be seen how successful it may be in humans.
