Ask 40,000 surgeons from around the world what they would pick to scientifically investigate and what do they choose? They voted for a new trial to establish whether changing to new surgical gloves and clean instruments just before abdominal wounds are closed up during surgery, would reduce infection. Thirteen thousand operations in seven countries later (in Benin, Ghana, India, Mexico, Nigeria, Rwanda and South Africa) the answer to the most common complication of surgery is in, and the results are published in the journal, the Lancet. Co-author Aneel Bhangu, senior lecturer in surgery at the University of Birmingham, tells Claudia how the findings of this apparently simple step, will change surgical guidelines around the world.

But what has social distancing and the pandemic done to our personal space? Science writer David Robson reports from one of the biggest brain sciences conferences in the world, Neuroscience 2022, in San Diego. New research using virtual reality, reveals that our personal space had shrunk. But, crucially, while our personal force field has reduced, it has also hardened. And according to the study, David says, we are now much less tolerant if this new, reduced 'peripersonal distance' is breached.
