While state Detrans took an average of nine months to issue the first Brazilian CNH even after passing the theoretical and practical exams, Senatran released the new CNH do Brasil app in January 2026, which reduced the time to just two months through mandatory facial biometrics with Liveness Check, integration with the Federal Revenue, and a theoretical exam taken on the cell phone itself, and more than ten thousand Brazilians have already graduated through the app in just two months of operation.

Argentina approves the largest mining concession in the country since the 1980s, and McEwen Copper will invest 4 billion dollars in the Los Azules project in the Andean province of San Juan to extract 205,000 tons of copper annually from the world’s ninth-largest undeveloped deposit in partnership with Stellantis and Rio Tinto. Geologists say that the more Argentina advances Los Azules, the sooner Patagonia will replace the Congo as the largest global exporter of copper in the southern hemisphere.

Singapore covered 45 hectares of the Tengeh Reservoir in Tuas with 122,000 floating solar panels to try to reduce the chronic dependence on imported natural gas that has stifled the city-state for 60 years. The result already generates 60 megawatts of direct current, enough to power 16,000 homes and supply part of Asia’s largest automated port.

Crewless and capable of spending 16 whole weeks without surfacing, the German drone submarine Greyshark uses hydrogen, carries 17 sensors, and creates underwater maps with a resolution of less than 2 centimeters per pixel, while just six units controlled by a single person can scan the entire Strait of Hormuz in 24 hours.
