Science and Technology

A creature with 20 arms gliding through the icy waters of Antarctica surprises researchers and intrigues science: the discovery of the genus Promachocrinus fragarius reveals unusual life forms and raises an inevitable question — how many marine “aliens” have yet to be found?

Construction

Shotcrete replaces manual plastering, can double or even triple productivity on site, and delivers more uniform walls; this industrialized technique has been gaining ground precisely where there is a lack of skilled labor.

Science and Technology

A South African father and son 3D print a drone structure, spend over 2 years destroying prototypes, and achieve 657.59 km/h with the Peregreen V4, a world record certified by Guinness that places the independent project among the fastest electric quadcopters ever built.

Science and Technology

The first authenticated artifacts from Japan’s largest imperial tomb emerge after more than 150 years as a university analyzes a ceremonial sword and armor sealed in paper from 1872; metallurgy reveals advanced techniques from the 5th century in a giant tomb nearly 500 meters long that the government keeps closed to science.

Science and Technology

In the “quintal” of the Solar System, an invisible cloud 3,400 times more massive than the Sun was discovered just 300 light-years away and revealed a hidden ocean of hydrogen that had gone unnoticed for decades until a groundbreaking technique exposed this giant stellar nursery.

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.

Egypt wants to draw 10 million cubic meters of water from the Nile per day into the desert, irrigate a new agricultural frontier, and build a city where there is currently only sand.

Ethiopia has banned gasoline and diesel cars, placed over a hundred silent electric buses on the streets of Addis Ababa, and now aims for half a million electric vehicles by 2030, all powered by Africa’s largest dam and a courage that few countries have shown.

Norway is drilling 27 kilometers of rock 392 meters below the bottom of a fjord to build the world’s largest and deepest underwater road tunnel — when completed, a 21-hour journey will be reduced to 10.

An astronaut spent 340 days in space while his twin brother stayed on Earth, and NASA found a “rejuvenating” effect, genes, microbiome, cognition, and immune system that revealed the biological cost of living outside the planet.

After 14 years of construction and a diplomatic crisis that nearly led to a military confrontation over control of the Nile, Ethiopia inaugurated the largest hydroelectric power plant in Africa — the dam is 170 meters high, holds 74 billion cubic meters of water, and generates 5,150 megawatts.
