Science and Technology

Scientists simulated what would happen if all of Earth’s oceans evaporated — and found the same mark on Mars, suggesting that one-third of the red planet was once covered by water.

Mining

The United States wants to extract minerals from the bottom of the Pacific at a depth of 4,000 meters — the problem is that 90% of the species living there are still unnamed, and in tests, life on the seabed decreased by 37%.

Renewable Energy

Climate change should be combated by solar and wind energy — but extreme heat reduces the efficiency of panels, violent winds shut down the turbines, and extreme rainfall floods entire power plants.

Interesting facts

On the seabed near Singapore, divers found the country’s first ancient shipwreck — the 14th-century ship carried 3.8 tons of Chinese porcelain and the largest collection of Yuan Dynasty blue and white pieces ever recovered from a shipwreck.

Construction

130 kilometers off the coast and with 260-meter-tall turbines, the world’s largest offshore wind farm is being assembled on the bottom of the North Sea — when complete, its 277 turbines will generate energy for 6 million homes in the United Kingdom.

Interesting facts

Astronomers have already found more than 6,000 planets outside the Solar System, but only 14 orbit two stars at the same time — and Einstein’s theory may explain why the others disappeared.

Interesting facts

During works to build an artificial island in Indonesia, workers dredged 5 million cubic meters of sand from the seabed and found over 6,000 fossils from a lost continent that submerged 10,000 years ago.

Industry

Usiminas closed a contract to supply 5,200 tons of special steel for the four most advanced frigates the Brazilian Navy has ever built — each ship carries 1,300 tons of plates that need to resist the sea and explosions.

Interesting facts

Scientists have reconstructed for the first time the complete skeleton of the largest crocodile that ever existed — it was almost 10 meters long, weighed as much as an elephant, and was capable of dragging dinosaurs into the water.

Oil and Gas

An oil drilling company drilled 6 kilometers of rock in Colorado in just 18 days — but this time it didn’t want oil, it wanted the infinite heat that exists inside the Earth at 300 degrees Celsius.

Construction

While in Brazil the São Paulo-Rio high-speed train never materialized, China plans to tunnel 120 km under the sea to connect two cities by rail — 90 km will be underwater, with trains at 250 km/h, and the 8-hour journey will be reduced to 40 minutes.

Nuclear Energy

China has just commissioned the world’s first commercial mini-nuclear reactor — it is only 14 meters tall, generates energy for 526,000 homes, and prevents 880,000 tons of CO₂ per year.
