Researchers at the University of Oregon have developed an artificial intelligence tool that can read genetic code the way large language models like ChatGPT read text. Scanning the genome for biological mutation patterns, the computer model traces pairs of genes back in time to their last common ancestor. It’s the first language model designed for […]

A middle-aged white man raises his sword to the skies and roars to the gods. The results of his genetic ancestry test have just arrived in his suburban mailbox. His eyes fill with tears as he learns that he is “0.012% Viking”. These are the scenes from a video advertisement for the TV-series Vikings. This […]

A new study , co-led by researchers at the Icahn School of Medicine at Mount Sinai, demonstrates that genes associated with autism risk are largely the same across people of different ancestries. The findings, based on one of the largest genomic studies of Latin American individuals to date, provide strong evidence that the genetic architecture […]

Scientists believe individuals of the most recently discovered hominin group (the Denisovans) that interbred with modern day humans passed on some of their genes via multiple, distinct interbreeding events that helped shape early human history. In 2010, the first draft of the Neanderthal genome was published, and comparisons with modern human genomes revealed that Neanderthal […]

The evolution of the human being has a complex form in which some branches bifurcate and form two different species and some different branches come together again and form individuals with a certain degree of hybridization. The only hominin remaining today is Homo sapiens and the last to disappear was Homo neanderthalensis. Neanderthals, our closest […]

When we say that someone is black or white, we may think that he or she belongs to a biological category defined by his or her color. Many people believe that skin pigmentation reflects belonging to a race, “one of the main groups that humans can be divided into according to their physical differences, for […]

The cause of Mars’ strongest quake The strongest quake recorded on Mars, which lasted six hours but left no visible signs on the planet’s surface, was caused by tectonic activity rather than a colliding asteroid. While scientists believe Mars does not have plate tectonics like Earth, the quake was likely caused by the release of […]

inheritance Author: Juan F. Trillo, PhD in Linguistics and Philosophy (U. Autónoma de Madrid), PhD in Literary Studies (U. Complutense de Madrid). The question about to what extent there is a direct relationship between the language spoken by a specific population and its genetic heritage has been controversial for some time, mainly due to the […]

About two-thirds of Jews today – or about 10 million people – are Ashkenazi, referring to a recent origin from Eastern and Central Europe. They reside mostly in the United States and Israel. Ashkenazi Jews carry a particularly high burden of disease-causing genetic mutations, such as those in the BRCA1 gene associated with an increased […]
