OpenAI will announce plans for a search engine powered by artificial intelligence on Monday May 13, Reuters reports. It's the latest challenge to search king Google and comes just one day before the tech giant's annual developer conference. On this week's Tech 24, Peter O'Brien looks at what might get Google sweating, amid changing search habits, a federal antitrust trial and smart new AI "answer engines".

It has been called an invisible epidemic. Every year, around 300,000 people in Europe die prematurely because of air pollution, according to the European Environment Agency. Those of us living in cities are particularly exposed to unsafe levels of fine particulate matter and nitrogen dioxide. The EU is trying to bring air quality closer to World Health Organization guidelines, but the political deal that has been struck includes a clause that will allow member states to delay action by up to 10 years, if specific conditions are met.

With just a few weeks to go before EU elections, the far right in France is on track for a comfortable win, if the polls are correct. The National Rally only just beat France's ruling party, Renaissance, in the last EU elections in 2019. This time, a wide gap has opened between the two, potentially striking a serious political blow to President Emmanuel Macron and his idea of a more powerful Europe. The National Rally has struck a chord with its campaign about purchasing power, standards of living and crime in French cities.
