Fun Fact: There is enough DNA in the human body to stretch from the Sun to Pluto and back  Fox News Source link

Image by Getty / NASA / Futurism Researchers have found that human stem cells are constantly under stress in the microgravity of space — activating hidden, ancient sections of DNA called the “dark genome.” In a study published in the journal Cell Stem Cell last week, a team of researchers led by Sanford Stem Cell Institute director Catriona Jamieson used …

For the first time in tropical latitudes, scientists have sequenced ancient DNA from the only mammoth endemic to North and Central America: the Columbian mammoth. The research revealed unexpected — and as yet unexplained — genetic differences that made these animals distinct from their northern counterparts. Columbian mammoths (Mammuthus columbi) were approximately 13feet (4 meters) tall and towered over their …

Assembly and quality control of DNA methylation data We assembled and processed with a harmonized pipeline14 (v4.1; see Code availability section) 2,430 bulk sample Illumina methylation array data of normal and neoplastic lymphoid cells from previous publications14,21,22,23,24,25,26,27,28,29,30. As healthy control samples, this dataset contained sorted CD19+ B cells (n = 40), CD3+ T cells (n = 35), peripheral blood mononuclear cells (n = 6) and whole-blood …

Chimpanzees, along with bonobos, are humans’ closest living relatives. In fact, you may have heard that humans and chimps share 98.8% of their DNA. But is this actually true? And what does “similar DNA” actually mean? The truth is that the frequently cited 98.8% similarity between chimp (Pan troglodytes) and human (Homo sapiens) DNA overlooks key differences in the species’ …

When it comes to interactions between animals and microbes in the ancient past, focus has primarily been on humans and our closest ancestors rather than extinct animals, such as mammoths. A new study led by Benjamin Guinet from the Swedish Museum of Natural History has analysed microbial DNA from no fewer than 483 mammoth remains. These remains span over one …
