‘A History of Contact’: Geneticists Rewrite the Story of Neanderthals and Other Early Humans

Detection of modern human-to-Neanderthal gene flow (H→N) and its consequences. Modern human-to-Neanderthal admixture causes a local increase in heterozygosity in the Neanderthal genome, a feature that enabled approaches to quantify and detect introgressed sequences. We used modern human-introgressed sequences in the Neanderthal genome to refine estimates of Neanderthal ancestry in contemporary humans by decomposing IBDmix-detected … Read more

Rapidly cooling weird creatures rewrite the physics of neutron stars

SciTechDaily

Neutron stars are among the densest objects in the universe. The material inside them is so tightly compressed that scientists don’t yet know what shape it takes. The core of a neutron star may be a thick soup of quarks, or it may contain exotic particles that could not survive anywhere else in the universe. … Read more

“Major” archaeological developments could help rewrite early human history

A researcher examining a Neanderthal hearth

An innovative technique used in a study of Neanderthal hearths – places where fires started – has been described by researchers as a ‘major’ development in archaeology, one that could help shed light on the behavior of prehistoric people. For a study published in the journal Naturean interdisciplinary team of researchers has discovered that a … Read more
