Our ancestors are known to have gotten frisky with other, now-extinct species of humans, leaving traces in our DNA to this day. A new analysis has found that a certain genetic variant inherited from the Denisovans may have given modern humans (Homo sapiens) an edge in populating the American continents. “Typically, genetic novelty is generated through a very slow process,” …

Whether it’s investigating the financials of Elon Musk’s pro-Trump PAC or producing our latest documentary, ‘The A Word’, which shines a light on the American women fighting for reproductive rights, we know …

Microsoft AI’s CEO Mustafa Suleyman is clear: AI is not human and does not possess a truly human consciousness. But the warp-speed advancement of generative AI is making that harder and harder to recognize. The consequences are potentially disastrous, he wrote Tuesday in an essay on his personal blog.  Suleyman’s 4,600-word treatise is a timely reaction to a growing phenomenon of …

TEL AVIV, Israel (AP) — Modern humans and Neanderthals were interacting 100,000 years earlier than previously thought, according to researchers who used CT scans and 3D mapping to study the bones of a child they believe was the result of interbreeding between the two distinct groups. The child, described in a recent study published in the peer-reviewed journal L’Anthropologie, was …

As most people who have used adaptive cruise control in traffic can no doubt appreciate, the most common event that required intervention was a car ahead cutting into the driver’s lane. These occurred about once every 8.6 miles, or 24.4 minutes, with 90 percent requiring intervention by the driver. Inadequate lane centering was the next most common event, occurring once …

Skull of a female A africanus – credit, Didier Descouens, CC BY-SA 4.0, From Ethiopia comes an incredible discovery—early humans seem to have potentially lived alongside the very apes they evolved from. The discovery centers around teeth: that of a member of the genus Homo, of which we are a part, found next to the tooth of Australopithecus, the last in …

Genetic mutation in key enzyme may explain why humans survived while Neanderthals went extinct  Archaeology News Online MagazineView Full Coverage on Google News Source link

A protein that helps synthesize DNA is different in modern humans than it is in Neanderthals and Denisovans — our closest extinct relatives — and new experiments in mice genetically modified to express the modern human version hint that this may have made us behave differently. That discovery, in turn, could shed light on why Neanderthals and Denisovans vanished, researchers …

If humans ever leave Earth to colonize other planets, they will need companions that are incredibly resilient and able to shrug off the lethal conditions found in outer space. Tiny animals called tardigrades, only visible under magnification, are perfect for the job. At about 0.004 inches long, a tardigrade can nap through a blast of ionizing radiation strong enough to …

A team of Japanese astronomers have spotted an explosion in deep space that is not only influencing the very star that triggered it, but also distorting the planet-forming disk surrounding it. The discovery suggests that if such explosive events are commonplace in young star systems, newborn stars and any planets that form around them may exist in environments far more …
