This photograph shows used nitrous oxide canisters being emptied during the recycling process, at DI Services' recycling factory in Saint-Pathus, north-east of Paris on May 7, 2026. In this noisy warehouse in Seine-et-Marne, canisters of nitrous oxide pile up by the thousands as beyond the public health scourge by the diversion of its use as "laughing gas" in party and recreational settings, it poses a colossal environmental challenge to gather and recycle these bottles which are abandoned all over France.

HERCEGHALOM, HUNGARY - MAY 06: Highway traffic passes through a mega construction project on the M1 Motorway some 30 kilometers west of Budapest on May 6, 2026 in Herceghalom, Hungary. The highway expansion is seen by manyt as an example of the business overlap between the Orban family and his close associates and family friends. Hungary is entering a new political era after the defeat of Orban, the architect of a self-described "illiberal democracy" who led the country for 16 years. Peter Magyar, leader of Hungary's center-right Tisza Party, is scheduled to be sworn in as the new prime minister this week. (Photo by John Moore/Getty Images)
