Across the sector of for-profit companies that manufacture gene therapy drugs, a sobering process is taking place. Even when they create a treatment that works, companies price it exorbitantly (about $2-3 million per patient), arguing that a one-time treatment saves the healthcare system years of supportive care. expensive. For diseases with less than 100 patients, …

Scientists have identified the oldest DNA ever discovered and, in doing so, revealed a complex ecosystem that existed two million years ago in modern Greenland, according to the results of a new study published in the journal Nature . The double helix-shaped molecule Deoxyribonucleic acid (or DNA for short) is present in almost every cell …

In the summer of 2008, in a cave nestled in the Altai Mountains in Siberia, Russian scientists have unearthed a finger bone fragment. At first, scientists assumed the fossil was from a Neanderthal – the cave was a known treasure trove of stone artifacts left behind by our thick-browed ancestors. But it was not until …
DNA study reveals how mysterious missing human shaped our immune system Read More »
An encounter with a mysterious and extinct human relative – the Denisovans – left a mark on the immune traits of modern Papuans, especially those living on the island of New Guinea. This is a new finding that we describe in a study published today in PLoS Genetics. It further suggests that our modern human …
Reconstruction of the Kap København formation two million years ago at a time when the temperature was significantly warmer than the far north of Greenland today. 1 credit A new ‘game-changing’ chapter in evolutionary history has been opened after two million years DNA DNA, or deoxyribonucleic acid, is a molecule made up of two long …

The oldest DNA ever recovered has revealed a remarkable two-million-year-old ecosystem in Greenland, including the presence of an unlikely explorer: the mastodon. The DNA, found locked in sediments in an area called Peary Land in the far north of Greenland, shows what life was like during a much warmer time in Earth’s history. The landscape, …
