With a career that balances mountaineering, teaching, and research, Hari Mix uses his background in Earth systems and geology to reconstruct past climates, examine mechanisms producing extreme precipitation, and teach the next generation of students about the planet.
According to Stanford University Mars experts, NASA’s latest Martian rover will drive a wave of exciting discoveries when it lands on the Red Planet – and possibly alter scientists’ understanding of the blue one it launches from.
Nikki Seymour will be studying a formation known as the Orocopia Schist in west-central Arizona, which may help provide a better understanding of the age or origin of things like copper deposits in Arizona.
Scientists are still trying to piece together how Earth transformed from a molten planet to one with living creatures walking around on its silicate mantle and crust. Hints lie in the strange ways materials behave under extreme temperatures and pressures.
“It’s rare to get this many sporangia with well-preserved spores that you can measure,” said Andrew Leslie, referring to a new species of ancient plant. “We just kind of got lucky in how they were preserved.”
Researchers have discovered an ancient plant species whose reproductive biology captures the evolution from one to two spore sizes – an essential transition to the success of the seed and flowering plants we depend on.
New research indicates river delta deposits within Mars’ Jezero crater – the destination of NASA’s Perseverance rover on the Red Planet – formed over time scales that promoted habitability and enhanced preservation of evidence.
Researchers present new evidence that the deoxygenation of the ocean wiped out biodiversity during one of the “Big Five” mass extinctions in Earth’s history – relevant information as climate change contributes to decreasing oxygen in the oceans today.
