We can’t easily monitor the health
of plants, by the time we see that they’re sick it’s usually too late to save
that. That’s an issue for your house plants, a field of wheat, orchards and
Karina Khambatta has developed a
way to use the waxy surface of leaves to monitor their health.
Astronomers from CSIRO and
Curtin University have used pulsars to probe the Milky Way’s magnetic field.
Working with colleagues in Europe, Canada, and South Africa, they have
published the most precise catalogue of measurements towards mapping our
Galaxy’s magnetic field in 3-D.
The Milky Way’s magnetic
field is thousands of times weaker than Earth’s, but is of great significance
for tracing the paths of cosmic rays, star formation, and many other
astrophysical processes. However, our knowledge of the Milky Way’s 3-D
structure is limited.
