Elpistostege watsoniIn the late 1930s, our understanding of the transition of fish to tetrapods -- and the eventual jump to modern vertebrates -- took an unexpected leap forward. The evolutionary a'ha came from a single partial fossil skull found o...

BERNARDO, NEW MEXICO - The juniper pollen has cranked up early this year, and the irrigators with groundwater pumps (legal or not, it's hard to know) are firing them up, but the most telling sign of spring was the kettling sandhill cranes this morning.

AVUELO has encountered one of the wettest and cloudiest dry seasons in memory. After a series of great acquisitions over core and important areas, our airborne science has stood down for several days with heavy cloud cover. So, what do AVUELO a...

As climate change warms the Arctic, permafrost is thawing, and carbon trapped within the soil is moving into the atmosphere. Permafrost stores twice as much carbon as the atmosphere, but the degree to which this frozen carbon will thaw and accelerate climate change has remained a point of scientific inquiry. Taking widespread on-the-ground permafrost measurements is not logistically feasible in the remote Far North.

Woolly Mammoths, Mammuthus primigenius,  have always held wonder for me. These massive, hairy -- and likely very smelly beasts -- lived alongside us for a time. If you stood beside him and reached way up, you might be able to touch his tu...

It's really hard to believe, but I will already be departing Panama tomorrow.  When I arrived a week ago, on February 5, I had a hunch but didn't fully appreciate just how busy our AVUELO ground and airborne teams would be keeping up wit...

New research challenges the assumption that only strong earthquakes cause liquefaction. Scientists from Poland demonstrated that even low-magnitude shocks (~M3.5) can trigger sediment deformation in water-saturated fine-grained sediments. This finding expands our understanding of seismic activity and its effects on geological structures.

Clarivate is the content-hoarding corporation that owns ProQuest, the Web of Science and EndNote, among many other services widely used in academia. Plus a ton of content. Today's announcement, "Introducing ProQuest Digital Collections, a new library subscription offering unparalleled breadth, value and access", sounds nice, doesn't it? And the first few paragraphs are certainly full of praise for the changes they're making.

More pocked with craters than any other object in our solar system, Jupiter's outermost and second-biggest Galilean moon, Callisto, appears geologically unremarkable. In the 1990s, however, NASA's Galileo spacecraft captured magnetic measurements near Callisto that suggested that its ice shell surface--much like that of Europa, another moon of Jupiter--may encase a salty, liquid water ocean.

Students at Merritt College must often wonder about the big expanse of empty land north of the campus -- loosely fenced off, dotted with piles of wood chips, gravel everywhere. Campus old-timers may remember it as rough parking lots. Oakland old-timers recall youthful exploits there in the "Devil's Punchbowl." I'm pretty sure no one alive remembers its days as the Leona Heights rock quarry.* I'm here to celebrate it all.
