Colossal Biosciences has included the blue antelope, extinct around 1800 due to hunting in South Africa, in its de-extinction program, a project that requires more than 100 genetic alterations from a reconstructed genome of one of the five museum specimens, using DNA editing, stem cells, and eggs from living antelopes.

The biotechnology company already working to bring back the woolly mammoth, the dodo, and the dire wolf has now included an extinct antelope on its list of animals it intends to “resurrect”. Colossal Biosciences announced this Thursday (30) that the blue antelope, scientifically named Hippotragus leucophaeus, officially described in 1766 and extinct around 1800 due to intensive hunting in South Africa, has joined the company’s de-extinction projects, which already include the woolly mammoth, the dodo, the moa, the thylacine, and the dire wolf. The blue antelope disappeared in just over three decades after being scientifically cataloged, a victim of European colonization that decimated entire populations of the animal for its hide and meat.

The challenge of bringing the antelope back is technically complex but has an advantage that other de-extinction projects do not. The genetic proximity between the blue antelope and living species such as the roan antelope and the sable antelope facilitates experiments because it allows the use of eggs and reproductive structures from existing animals as a basis to generate embryos with edited characteristics to approximate the extinct species. The Colossal team estimates that recreating the characteristics of the blue antelope will require more than 100 alterations to the genetic code, a number that reflects both the complexity of the process and the limitation of available information about an animal that only survives in five specimens preserved in museums around the world.

A Colossal quer ressuscitar antílope extinto há 200 anos com mais de 100 alterações genéticas. Só existem 5 exemplares em museus. Entenda o projeto de desextinção.

The starting point for the de-extinction of the blue antelope is a detailed genome reconstructed from one of the five museum specimens. Despite the scarcity of available genetic material, researchers were able to sequence the preserved DNA and identify the differences between the extinct antelope and its closest living relatives, a mapping that guides which genetic alterations need to be performed to transform cells from a roan antelope into something genetically similar to the disappeared animal.

Forget petroleum-based asphalt: a Scottish company transforms 684,000 plastic bottles into one kilometer of road that is 60% more resistant and up to 10 times more durable, and the technology has already started replacing traditional asphalt in more than 30 countries.

With billions in loans, China is rebuilding Nigeria’s railway network from scratch, abandoning the British colonial tracks that have turned to scrap and creating a corridor of over 1,300 km to take the load off the roads of Africa’s largest economy.

Austrian engineers have developed an inflatable concrete technology that transforms flat slabs into domes using only air pressure, eliminating scaffolding and temporary forms, and potentially changing the way bridges, tunnels, and curved roofs are constructed worldwide.

Australia prepares to dredge 96.5 million m³ in Moreton Bay to deepen, widen, and realign channels of the Port of Brisbane, in a project of up to 25 years designed to accommodate larger ships and enhance maritime safety and regional port efficiency.

Study solves great ancient mystery: remains of Philip II, father of Alexander the Great, are identified in Vergina and resolves the enigma of the Macedonian royal tombs that had lasted half a century.

Larger than the Toyota Hilux and with a towing capacity of 3.5 tons, the new MG U9 2026 features a 2.5 turbodiesel engine, 520 Nm, 4×4 traction with three locks, and an almost full-size build.

For the first time in history, a submarine cable will descend to four thousand meters deep under the ice of the North Pole to ensure that the internet between Europe and Asia no longer depends on conflict zones in the Middle East.

While the world discusses geopolitics, China is quietly closing a deal with its Kazakh neighbor to secure grain supplies during any global food crisis, with more than 3,600 Kazakh companies already able to export directly to the Chinese market.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

Amid the United States’ economic blockade, China delivers 15,000 tons of rice to Cuba as part of a 60,000-ton donation personally approved by Xi Jinping. The package includes 80 million dollars and solar panels for hospitals.

The James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.
