Phys.org / Southern Ocean may flip from carbon sink to carbon source under mitigation scenarios

Plans to limit the global temperature rise to 1.5°C above preindustrial levels depend on reaching net-zero emissions and, in many cases, actively removing carbon dioxide (CO2) from the air. While this helps limit extreme ...

Phys.org / Why are the stars around our galaxy's black hole missing their companions?

A new study suggests that the young stars orbiting the Milky Way's central black hole may have a surprisingly ordinary origin. But the black hole's influence may be what makes their origin look more exotic than it really ...
