The recent discovery in the octopus genome suggests that cephalopods may have the oldest sex chromosomes among all animals. This finding challenges the previous notion that sex determination in these creatures was purely based on observation. Biologists have traditionally differentiated between male and female octopuses based on their ability to lay eggs or produce sperm.
The existence of giant star-shaped sand dunes in modern deserts has puzzled scientists for years, especially considering that only one such dune has been identified in the geological records, dating back more than 250 million years in north-east Scotland. This is surprising, given that these unique dunes can be found in various deserts across the
In a groundbreaking development, scientists have achieved a significant milestone by successfully growing small yet intricate models of human organs from live fetus cells. This pioneering research not only provides valuable insights into human development but also holds the potential for innovative treatments for prenatal malformations. These organoids, although not exact replicas of organs, closely
