Q&A: How physics could explain why people respond differently to coronavirus infection

The immune system is constantly hedging its bets to rearrange itself to protect from future infection, says physicist Aleksandra Walczak. Image credit - Ketut Subiyanto/pexels.com

Some people’s immune systems contain pre-existing protection against coronavirus, indicating that they have encountered a similar infection to Covid-19 before, according to Dr Aleksandra Walczak, a physicist at École Normale Supérieure in Paris, France. Her team uses statistical physics to model the human immune system and try and predict how it will behave. She is currently … Read more

Studying Asian glaciers provides glimpse into future of extremes

Scientists may have solved a 25-year-old puzzle about the mysterious behaviour of certain glaciers in High Mountain Asia. In most of this region, they are shrinking; but in the northwest, they are growing. High Mountain Asia includes ranges that span the borders of Afghanistan, Bhutan, Nepal, India, China and Pakistan. The rate of glacier melting … Read more
