Curiosity set out to answer the question: Did Mars ever have the right environmental conditions to support small life forms called microbes? Early in its mission, Curiosity’s scientific tools found chemical and mineral evidence of past habitable environments on Mars. It continues to explore the rock record from a time when Mars could have been …

Daran-Lapujade’s lab took human DNA (in red) encoding core functions in muscle cells and inserted it into the DNA (chromosomes in purple) of a yeast cell (in yellow). The humanized yeast can be used as a tool for medical studies, for example in drug screening and cancer research. Credit: Ella Maru Studio / Pascale Daran-Lapujade …

Precise measurements show that Earth’s rotation has been mysteriously slowing down since 2020, making the day longer. Precise astronomical observations, combined with atomic clocks, have revealed that the length of a day is suddenly getting longer. Scientists don’t know why. This has critical impacts not just on our timekeeping, but also on things like GPS …
