Phys.org / Ancient DNA challenges family assumptions in medieval Scandinavian graves

When archaeologists find adults and children buried together in medieval graves, it is often assumed that they were members of the same family. A new study from Stockholm University in Science Advances suggests otherwise.

Dialog / Dark energy flips its sign, but the Hubble tension refuses to budge

For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the Supernova Cosmology Project, led by Saul Perlmutter, and the High-Z Supernova Search Team, led by ...

Phys.org / Could exoplanets locked in eternal day and endless night support life?

Ever so slightly bigger than Earth, the exoplanet LHS 3844b orbits its parent star, LHS 3844, a red dwarf 48.5 light-years from our solar system. Its rotational speed mirrors its orbital speed. The result? One side of LHS ...
