Neanderthal is an insult still thrown around to suggest someone is stupid and out of touch.

The more we learn about our Stone Age cousins, the more it seems the opposite is true. Neanderthals were not brutal cave dwellers they made sophisticated tools, threads and art and buried their dead with care.

A new discovery in a Siberian cave this week reveals an intimate portrait of Neanderthal family life and suggests it may be time for Homo sapiens to shed that superiority complex once and for all.

Scientists have discovered the oldest known family group using ancient DNA from Neanderthals who lived in Chagyrskaya Cave in southern Siberia, Russia.

The riverside hunting camp, about 54,000 years ago, was home to a tight-knit community of about 20 Neanderthals, including a father and his teenage daughter, a young man who may have been a nephew or cousin, and a grown woman who was of the second degree. relative—perhaps an aunt or grandmother.

The researchers also detected an unexpected pattern of female migration between different lines of genetic ancestry.

The most likely explanation for this was that most of the Neanderthal women in the small Chagyrskaya group came from another community – perhaps to join their partner’s family.

If you lived in London during the Black Death, the odds of defeating the bubonic plague were not good – it killed 50% of Europe’s population within seven years.

The lucky survivors of the Black Death that ravaged Europe had – in part – their genes to thank, new research has discovered. Using DNA extracted from the teeth, scientists were able to identify a key genetic difference that influenced who survived and who died from the disease.

That genetic inheritance still affects the human immune system today, according to researchers, but in a less desirable way when it comes to certain autoimmune diseases.

The V-1302 John Mahn, a German ship sunk by the British in World War II, continues to leak toxic elements onto the seabed.

Shipwrecks exert a unique pull on our collective imagination—the lure of sunken treasure and war battles won and lost. But while long-lost ships on the ocean floor can function as artificial reefs and have tremendous storytelling value, they can also pose a risk to the marine ecosystem.

A World War II ship is still leaking explosives and other toxic elements onto the floor of the North Sea more than 80 years after it sank, according to a new study that analyzed samples collected from the ship’s steel hull as well as sediment from i swear

The samples revealed heavy metals such as nickel and copper, in addition to arsenic and explosive compounds.

The researchers involved in the study estimated that the wrecks from both world wars – found in the Earth’s oceans – contain between 2.5 million and 20.4 million metric tons of petroleum products.

One of the most powerful explosions in the universe was detected on October 9.

The gamma-ray burst – seen as a long, bright pulse of light – was the birth cry of a black hole.

It happened when a massive The star, located in the constellation Sagitta, about 2.4 billion light-years away, collapsed in a supernova, forming the new black hole.

Billions of years after traveling through space, the colossal black hole explosion has finally arrived in our corner of the universe, and scientists say it’s a rare opportunity to explore long-standing questions about this type of explosion.

Meanwhile, the James Webb Space Telescope captured a spectacular image of the strange plumes of cosmic dust and gas that mark the beginning of a stellar life cycle.

A 3-tonne sunfish, believed to be the world's heaviest bony fish, has been found in Azores waters.

The carcass of a giant sunfish was discovered floating in the seas around the Portuguese archipelago of Azores in December. Weighing 2,744 kilograms (3 tons), it is believed to be the heaviest bony fish in the world.

A new study has revealed that the animal had a bruise that could provide clues to its death. The researchers found traces of red paint – used to cover the keels of boats – embedded in the wound. However, it is not known whether the impact occurred before or after the creature’s death.

The discovery was “a sign that the oceans are still healthy enough to support the heaviest species in existence,” said José Nuno Gomes-Pereira, a postdoctoral researcher at the Atlantic Naturalist Association, “but a warning for more conservation in what concerns the pollution and the boat. traffic near oceanic islands.”
