Four 24-meter suction sails that generate up to 7 times more lift than traditional sails have been installed on a Maersk oil tanker. The autonomous system can reduce consumption by up to 20% and is already recording savings of up to 5.4 tons of fuel per day at sea, with annual cuts potentially reaching thousands of tons on a single vessel.

A hidden metal piece in the bow redesigns the water flow, reduces drag, and can save over 10,000 tons of fuel per year; this invisible solution allows giant ships to cut millions in costs without changing engines or routes.

The world’s first container ship powered by renewable ammonia promises to avoid around 11,000 tons of CO₂ per year. The vessel, scheduled to operate in 2026, will connect Norway, Germany, and the Netherlands on one of the shortest and most strategic routes in Europe.

Nine giant ships of up to 210,000 gross tons equipped with dual fuel ammonia engines are being launched by Japan and Belgium. The project includes the world’s first Capesize vessels using this fuel, with contracts of up to 12 years, marking the beginning of a carbon-free ocean fleet starting in 2026.

With a length of 121 meters and four rigid sails of 36 meters that automatically rotate to capture the wind, Canopée is the world’s first hybrid industrial cargo ship powered by wind, used to transport rockets and reduce fuel consumption by up to 30% on transoceanic routes.

The German ship Bottsand splits its hull in two halves in the middle of the ocean to swallow spilled oil on the surface, separating the oil from the water inside a 790 cubic meter tank and then closing again. It is the only ship in the world factory-designed to split in half as part of normal operations, and the crew of six people who operate everything is civilian.

Seen from space, an image taken by an astronaut shows an unlikely oasis in the Saudi Arabian desert, protected by a terrain that slows the advance of sand, surrounded by green circles, remnants of an extinct lake and nearly 10,000 years of preserved history.

While the U.S. still faces limitations in deep space, China is developing unprecedented technology with strategic satellites that maintain communication with the far side of the Moon and aims for dominance by 2030.

In Botswana, a salt flat of up to 16,000 km² that was once an African megalake spends months as an absolute white desert, but during the rainy season it transforms into a shallow sea that reappears from nowhere and can be seen from space in the middle of southern Africa.

The Blood Falls of Antarctica hide a living ecosystem trapped under the ice for over 2 million years, where microbes survive without light, without oxygen, and without ever having seen the Sun.

Bavarian archaeologists unearthed a medieval skeleton that had an articulated iron hand in place of its left arm, and the discovery reveals that doctors were already creating sophisticated prosthetics over 500 years ago.
