[NEWS] Five D-Brief links: atomic clocks and dark matter, Chang'e-4, Phoebe, health, exoplanets

• D-Brief notes that upcoming generations of atomic clocks can be so accurate that they might be able to detect dark matter.


• China's Chang'e-4 moon lander is en route to our nearest partner world, D-Brief reports.


• D-Brief notes that the ratio of hydrogen to deuterium in the water of the Saturn moon of Phoebe differs not only from that on Earth but that of the icy worlds in the Saturn system, suggesting Phoebe formed elsewhere.


• The stresses of living in space makes organisms like mice and human beings prone to infections, D-Brief notes.


• A study of nascent exoplanets in a starforming region of Taurus, some 450 light-years away, provides invaluable information about how planets form, D-Brief observes.
