Year(s) Without a Summer

In 1816, the Northern Hemisphere experienced the coolest summer on record, triggering crop failures and famine throughout Europe. The “Year Without a Summer” was later attributed to the eruption of Mount Tambora in 1815, a volcano in modern day Indonesia that killed an estimated 92,000 people.

In the News: Surveys and Shark Whisperers

Between shark whisperers and access to a soon to be unprecedented amount of survey data, scientists hope to better their understanding of these elusive creatures. Rather than portraying them as the monsters of “Shark Week,” these studies hope to address ongoing conservation issues that go beyond just sharks and affect the entire ocean:

Rulers of the Sea

Even though we were excited to see a Tyrannosaurus rex in “Jurassic World,” it is probably best that they stayed in the Cretaceous. Humans and dinosaurs certainly do not mix, but ancient mammals lived side-by-side with the T. rex. That is, until the asteroid killed off all non-avian dinosaurs in the Cretaceous-Paleogene [K/Pg] extinction event, leaving an ecological void for mammals to evolve and ultimately dominate in terrestrial ecosystems. A recent study published in PNAS by paleobiologists at UC San Diego suggests a similar story unfolded with the evolution of fish in the oceans.

Microbes and Middle Schools

Editor’s Note: For our third installment in the International Year of Soils series, we spoke with Dr. Julia Stevens about her work with soil microbiology and connecting students to science. To learn more about her work with middle school students, click here.


For Julia Stevens, a challenging aspect of teaching microbiology to middle schoolers is the sheer scope of something so small.
