Science and Technology

NASA researchers test new material capable of withstanding contact with melted lunar dust, one of the biggest challenges of space missions: technology may help astronauts produce oxygen, fuel, and structures using resources found on the lunar surface itself.

Science and Technology

Scientists are already cultivating algae that produce three times more biomass than conventional ones and can become fuel for ships and planes without a drop of oil, but the energy sector doesn’t want to buy what no one yet produces at scale, and producers don’t want to expand without a guaranteed buyer.

Science and Technology

Scientists at Rice University have created a material that boosts the interaction between electricity and magnetism by up to 100 times and could pave the way for much faster and more economical computers.

Science and Technology

Researchers use artificial rays to transform natural gas into methanol and create cleaner fuel; the technology reduces emissions, utilizes wasted methane, and advances global sustainable energy solutions.

Mother and daughter build a 70 m² house with more than 8,000 discarded glass bottles and impress with their creativity; known as the Casa de Sal, the property is located on Itamaracá Island, in Pernambuco.

Workers were opening a new road connection near the Marginal Tietê when they found, in the underground of the construction site, remnants of locomotives, wagons, and boilers from the 19th century linked to the forgotten history of Lapa.

Instead of burning or burying old tires, an American city is transforming about 2,000 of them into the street itself, paving its first sections with a quieter and more durable rubber asphalt.

China transforms desert-devastated area into the world’s largest artificial forest, planting trees for 60 years, blocking sand that reached Beijing, and creating a “green lung” of 92,000 hectares in a region once considered lost.

Greek island offers free housing for volunteers, but there’s a condition: you need to take care of rescued cats.

Engineers want to carve through Africa with a giant canal to bring water from the world’s second-largest river to a dying lake on the edge of the Sahara Desert that has already lost 90% of its water.

China has deployed snake-shaped robots to slide along power lines, where they have already inspected over 130 kilometers of cables using cameras and sensors to detect damaged wires, worn-out parts, and overheating.
