New study questions source of rare Earth metals that provide clues to life's origins
A new study in Geochemistry, Geophysics, Geosystems is reviving a decades-old debate about how Earth's rarest elements came to exist on our planet - theories that have implications for the origin of life.

NASA Mars orbiters reveal seasonal dust storm pattern
For six recent Martian years, temperature records from NASA Mars orbiters reveal a pattern of three types of large regional dust storms occurring in sequence at about the same times each year during the southern hemisphere spring and summer, according to a new study in Geophysical Research Letters.

#538 Nobels and Astrophysics
This week we start with this year's physics Nobel Prize awarded to Jim Peebles, Michel Mayor, and Didier Queloz and finish with a discussion of the Nobel Prizes as a way to award and highlight important science. Are they still relevant? When science breakthroughs are built on the backs of hundreds -- and sometimes thousands -- of people's hard work, how do you pick just three to highlight? Join host Rachelle Saunders and astrophysicist, author, and science communicator Ethan Siegel for their chat about astrophysics and Nobel Prizes.
