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 …

Tissue slide preparation Mouse C57 embryo sagittal frozen sections (MF-104-11-C57 and MF-104-13-C57) were purchased from Zyagen. Freshly collected E11 or E13 mouse embryos were snap frozen in optimal cutting temperature (O.C.T.) compounds and sectioned at 7–10 μm thickness. Tissue sections were collected on poly-l-lysine-coated glass slides (Electron Microscopy Sciences, 63478-AS). Juvenile mouse brain tissue (P21) was obtained from the C57BL/6 mice …

Scientists decoded the true identity of the mezcal worm, long shrouded in myth. Credit: Stock A genetic study has finally solved the mystery of the worm inside mezcal bottles. While speculation ranged from butterflies to weevils, DNA analysis revealed that all sampled larvae came from a single moth species, Comadia redtenbacheri. This insect is a traditional delicacy in Mexico, believed …

For the first time, researchers have uncovered direct genomic evidence of the bacterium behind the Plague of Justinian — the world’s first recorded pandemic — in the Eastern Mediterranean, where the outbreak was first described nearly 1,500 years ago. The landmark discovery, led by an interdisciplinary team at the University of South Florida and Florida Atlantic University, with collaborators in …
