The Science of Lab-grown Diamonds
The Science of Growing 100,000 Carats of Real Diamonds in a Lab In Silicon Valley, where seemingly anything can be produced in a lab, so can diamonds. Diamond Foundry recently opened a new diamond lab in South San Francisco that … Continue reading
Celebrity fossil reveals all for science
With the help of an artist, a geology professor has figuratively speaking breathed life into one of science’s most well-known fossil species; Agnostus pisiformis. The trilobite-like arthropod lived in huge numbers in Scandinavia a half-billion years ago. Today, this extinct … Continue reading
Evolution of ‘true frogs’ defies long-held expectations of science
New research shows, in contrast to expectations, ‘the rapid global range expansion of true frogs was not associated with increased net-diversification.’ Paleontology News — ScienceDaily
Cryospheric science: Asia’s glacier changes
Nature Geoscience 10, 621 (2017). doi:10.1038/ngeo2995 Author: Daniel Farinotti Mass changes in High Mountain Asia’s glaciers have been under dispute for almost a decade. An analysis of satellite data archives provides an observation-based mass budget for every single glacier in … Continue reading
Planetary science: Bypassing the habitable zone
Nature Geoscience 10, 545 (2017). doi:10.1038/ngeo2996 Author: Andrew P. Ingersoll In our own solar system, Venus is too hot, Mars is too cold and Earth is just right. Simulations show that making an icy planet habitable is not as simple … Continue reading
Cryospheric science: The power of glacial microbes
Nature Geoscience 10, 329 (2017). doi:10.1038/ngeo2933 Author: Elizabeth B. Kujawinski Organic carbon fluxes from glaciers are a key control on biogeochemical cycles in polar regions. Two analyses of carbon cycling in glaciers show the importance of glacier–surface microbial communities in … Continue reading
Earth science: Rock samples indicate water is key ingredient for crust formation
By examining the cooling rate of rocks that formed more than 10 miles beneath the Earth’s surface, scientists have found that water probably penetrates deep into the crust and upper mantle at mid-ocean spreading zones, the places where new crust … Continue reading

Planetary science: A nickel for your planet’s thoughts
Nature Geoscience 10, 249 (2017). doi:10.1038/ngeo2909 Author: Paolo A. Sossi Variability of iron isotopes among planetary bodies may reflect their accretion or differentiation histories. Experiments suggest nickel may be the ingredient controlling iron isotope signatures, supporting fractionation during core formation. … Continue reading
