Here’s a summarized version of the article:
This week’s recap highlights intriguing scientific studies, including Neanderthal and modern human connections, astronomical phenomena, and ecological insights.
A study reveals that Neanderthal men had more offspring with Homo sapiens women than the reverse, leading to a "Neanderthal desert" in the modern human genome, particularly on the X chromosome. This suggests a strong sexual bias favoring these pairings, evident in the genetic patterns observed over 200,000 years.
In astronomical news, the red supergiant star WOH G64 underwent a drastic change to a yellow supergiant, providing rare insights into the life cycles of such stars and their potential fate—either exploding as a supernova or collapsing into a black hole.
Ecologically, researchers examine female caribou, which uniquely possess antlers, for their nutritional benefits. Postpartum, these females might eat their shed antlers for vital nutrients, enhancing calf survival.
Finally, a new species of dinosaur, Spinosaurus mirabilis, has been discovered in the Sahara, notable for its scimitar-shaped skull. This finding reinforces the understanding of the semi-aquatic lifestyle of these giant carnivores, emphasizing their role as charismatic megafauna.
