‘Absolute miracle’ breakthrough provides recipe for zero-carbon cement

Concrete is the world’s most used building material, and making it is a particularly dirty business – concrete production alone is responsible for about 8% of total global CO2 emissions. But according to new research from the University of Cambridge, throwing old concrete into steel-processing furnaces not only purifies iron but produces “reactivated cement” as a byproduct. If done using renewable energy, the process could make for completely carbon-zero cement.

Chile to create network of protected salt flats

Currently, only around 8% of Chile’s salt flats are protected. The new network of protected salt flats will raise that to 25%. This also aligns with the 30×30 goal as outlined by the global Convention on Biological Diversity, which ensures that at least 30% of the planet’s ecosystems are protected by 2030. The protection plan is part of the broader National Lithium Strategy, which seeks to make Chile the world’s lead producer of lithium, a critical component of EV batteries.

Crime in England and Wales has plummeted 80% in 30 years

As of 2024, violence, burglary, and car crime have been declining for 30 years and by close to 90%, according to the Crime Survey for England and Wales (CSEW). The drop in violence includes domestic violence and other violence against women. Anti-social behavior has similarly declined.
