"If we leave writing to AI chatbots, we won't just lose a craft and the skills. Because writing is more than that. Writing is thinking", argues Giorgio Iemmolo, Director of the Language Centre at ETH and the University of Zurich.

What is your opinion?
Giorgio Iemmolo, is learning possible without writing?
AI chatbots are taking over writing for students and researchers. Linguist Giorgio Iemmolo explains what we are jeopardising in the interest of efficiency gains.

Mayor of London, Sadiq Khan @london.gov.uk · 8d
184 years earlier than predicted, London has met the legal limits for toxic NO2 for the first time.

This historic milestone proves that bold action like expanding ULEZ works, protecting children’s health and giving millions cleaner air to breathe.
London Ulez reduced nitrogen dioxide to legal limit, mayor says
The mayor of London says the fall in airborne toxins is due to the Ultra low emission zone expansion.

Our paper examining the chemical conditions of past chamber studies is out! This work explores assumptions made when creating SOA parametrizations based on laboratory data, and can hopefully point to ways of improving model representation of SOA.
