The window shuts tonight. Eight international internships are open across 7 countries, and every one of them closes today, 28 July 2026. Several are paid, and paid well: an acoustics and vibrations role at a Montreal consulting firm at CAD 7,500 a month, polymer research in Switzerland at up to CHF 2,500, and two bio based science placements in Ghent. Alongside them sit some of the most meaningful communications roles in the world: coordinating ocean acidification science at the IAEA in Monaco, and reporting from inside the UN programme clearing unexploded bombs in Laos. From biotech and materials science to climate and ocean communication, this is a genuinely global set of last day internships.
The funding is refreshingly clear on the science side and honest elsewhere. The two Belgian bio based placements pay €300 a month, the Canadian acoustics role CAD 7,500, the Swiss polymer role CHF 2,100 to 2,500, and the Italian NGO communications role €600. The Qatar, Monaco and Laos roles at the Global Green Growth Institute, the IAEA and UNDP offer experience at world class institutions rather than a stated salary. Every application closes today, 28 July 2026.

Tell the story of a country clearing its own war.
Eight internships, seven countries, one shared cut off. The paid science track is the strongest it has been in a while, from a CAD 7,500 acoustics role in Montreal and polymer research in Switzerland to two bio based fermentation placements in Ghent, all routed through IAESTE. The institutional track is just as compelling in a different way: coordinating ocean acidification science at the IAEA in Monaco, climate communications at the Global Green Growth Institute in Qatar, campaign work for an NGO in Italy, and reporting from inside the UNDP unexploded ordnance programme in Laos. Whether you are a chemistry student chasing a paid lab role or a communicator drawn to the UN, one of these fits, and all of them close today, 28 July 2026. Send the application before the day is gone.
