Researchers have reconstructed the genetic code of the woolly mammoth in unprecedented detail after discovering fossilized chromosomes in the skin of a 52,000-year-old carcass preserved in the permafrost of Siberia. The mammoth’s luxuriant mane led researchers to name it after Chris Waddle, the mulleted former England footballer. It was freeze-dried after death, a process that … Read more
Photo: Anna Kukekova, University of Illinois Urbana-Champaign Domesticated animals play a prominent role in our society, with two-thirds of American families enjoying the companionship of pets and many others relying on animal products for their dietary needs. But the process of domestication remains somewhat of a mystery. Convincing wild animals that they are safe enough … Read more
About 10,000 years ago, a small population of woolly mammoths became isolated on Wrangel Island off the Siberian coast. This isolation was the result of rising sea levels, a phenomenon we are all too familiar with today. Within just two generations, the woolly mammoth population on Wrangel Island grew from just eight individuals to a … Read more

Researchers have identified it Tmesipteris oblanceolataa fern from New Caledonia, which has the largest recorded genome, surpassing the previous record holder Paris japonica. This discovery, described in the iScience magazine, reveals that this fern contains more than 50 times more DNA than humans and highlights the significant implications that larger genomes have for plant biology … Read more
