The simplest approach is often the best, whether you’re talking about writing a news story, building an airplane or, in the case of one of this week’s discoveries, turning the desert into color. green.

Embankment, an ancient and low-tech construction technique, is having a profound impact on the degraded land in two different places.

In Tanzania, farmers use bunds – barriers that at their most basic level, simply mound – yes Pick the arid, overgrown and eroded land has turned green. Barriers keep water from flowing over the ground and allow it to penetrate the earth.

Grass seeds sown inside the bunches will grow, and over time the greenery will outgrow them, dramatically alter the landscape.

Similar techniques are restoring peatlands, wetland landscapes have large carbon reserves in soil, in Northern Ireland, has the potential to improve the quality of drinking water there.

Dig this

Lost cities can have a powerful appeal to the imagination, and archaeologists working in Iraqi Kurdistan believe they may have located a city.

Excavations of the 2,000-year-old fortress in the Zagros Mountains revealed fortifications nearly 2.5 miles (4 km) long, two smaller settlements, rock carvings and a religious complex.

The research team believes the ruins may be part of a lost royal city called Natounia. The community was part of Adiabene, a small kingdom that paid tribute to the neighboring Parthian Empire, which stretched through parts of Iran and Mesopotamia.

The city is known only because of the small details found in rare coins, but archaeologists have carefully pieced together the clues found during their digging at the ancient site.

Wild Kingdom

The Patagonian Ice Dragon is what scientists call an extreme species, or a creature that can live in extreme environments.

It’s a fitting name for an ice-dwelling insect of the Andes . mountains in South America. This tiny insect is rare because the glaciers it calls home are melting rapidly due to global warming. Entomologist Isaí Madríz is trying to figure out everything about the mystery the inner workings of endangered species, including why it’s so unlikely you’ll spot a young ice dragon.
His mission is featured in the new CNN documentary “Patagonia: Life on the edge of the world“discovery of one of the wildest places on Earth. Watch the latest episode at 9 p.m. ET/PT Sunday.

Black holes are powerful cosmic phenomena, but they do not emit any light. This means finding one can take several years of detective work for astronomers.

Researchers are called “black hole police” after making previous discoveries that say they have found a particularly elusive type of black hole for the first time outside our galaxy.

Located in the Large Magellanic Cloud, a neighboring galaxy, the newly discovered space object is at least 9 times the mass of our sun. Called VFTS 243, it orbits a hot, blue star 25 times the mass of the sun, making it part of a binary system.

The astronomers said they were confident their discovery was watertight.


A diner finds dinosaur footprints in the courtyard of a restaurant in Sichuan province, China.
A diner with sharp eyes at a restaurant in Sichuan province, China Discovered dinosaur footprints 100 million years old.

The prints in the restaurant yard belong to two species of sauropods – the plant-eating dinosaurs known for long neck and tail, according to paleontologist Lida Xing of China University of Geosciences in Wuhan, who was exposed to the diner.

Rapidly developing China is enjoying the golden age of dinosaur discoveries, but Xing says paleontologists like him have to get out quickly. He tries to verify any potential discoveries discovered by the public within 48 hours for fear that they could be destroyed by construction work.

In this case, he got lucky. The restaurant owner fenced the area to prevent people from stepping on the pit and possibly built a shed to protect them.
