Cement manufacturing is one of the largest sources of CO₂ emissions in the construction industry. At the Department of Architecture, Karen Antorveza Paez, who has just completed her doctorate at ETH Zurich, is researching an alternative that works in a different way: instead of firing rocks at over 1,000°C, she is getting bacteria to bond grains of sand together into solid architectural elements.

Bacteria turn a virus’ own weapon against it

Researchers have uncovered a new way bacteria detect viral attacks: a virus-produced enzyme cuts a bacterial sensor protein, triggering a self-destructing immune response. The discovery could lead to more effective phage therapies against antibiotic-resistant bacteria and provide
