A tardigrade is given a dose of CRISPR tools to change one of its genes, and those of the eggs it will produce. Credit: 2024 Tokiko Saigo et al. Some species of tardigrades are highly and unusually resilient to various extreme conditions that are fatal to most other life forms. The genetic basis for these … Read more
Woolly rhinos were once widely distributed across northern and central Eurasia before becoming extinct about 10,000 years ago. Credit: Mauricio Anton Advanced computer modeling shows that persistent human hunting contributed to the extinction of the woolly rhino by blocking their migration to new habitats during post-ice age warming. This underlines the continued impact of human … Read more
Resume: Researchers created the first complete chromosome sequences of non-human primates, revealing significant variations in Y chromosomes between species. This groundbreaking study provides crucial insights into the rapid evolution of these chromosomes and previously undiscovered regions of great ape genomes. The research highlights how these sequences can influence our understanding of human evolution. The findings … Read more

Researchers from the University of Bern have successfully dated a prehistoric agricultural settlement in northern Greece to between 5328 and 5140 BC, using dendrochronology and a significant radiocarbon spike in 5259 BC, from a cosmic event known as a Miyake event. This breakthrough provides an accurate chronological reference for other archaeological sites in southeastern Europe … Read more
