How Halogens Caused the End-Permian Extinction

How Halogens Caused the End-Permian Extinction

The end-Permian extinction was devastatingly destructive on a scale hard to comprehend. Ozone degradation and large fluctuations in temperature made the earth unsuitable for habitation, leading to the extinction of over 90 percent of all marine life and over 70

A study of strike-slip indicators on Ganymede reveals striking findings Do objects in outer space, which appear so enigmatic and extraterrestrial from our perspective, actually have geologic processes that resemble what we have on Earth? According to researchers from the

Implementing global changes in food production and consumption. Of all the apocalyptic scenarios one can imagine—war, disease, explosion of the sun—one that may not come to mind is humanity’s food system.  Some models predict that our robust food system, which

Improving the localization of rare soft-tissue fossils Think of a fossil. What do you see? Perhaps dinosaur bones, teeth, or mollusk shells? When we think of fossils, we traditionally picture hard tissue parts. However, more rare soft tissue fossils are

Legionnaires’ Disease Linked to Some CT Watersheds

In the 21st century, some believe water contamination in the United States is an issue of the past. Advancements in plumbing, sanitation, and water treatment have drastically reduced the number of diseases spread through infected water. In Connecticut, however, one

Are You There, Exoplanets? It’s Me, Earth

Space: the final frontier. Researchers at Yale work to boldly go where no researcher has gone before. With a newly designed EXtreme PREcision Spectrograph (EXPRES) that will clarify pre-existing data, Professor Debra Fischer and graduate student Lily Zhao are leading

The Confounding Simplicity of Coastal Carbon

The Confounding Simplicity of Coastal Carbon

What do a Florida mangrove swamp, a Connecticut cattail-lined salt marsh, and an Oregon tidal freshwater forest all have in common? Sure, that funky low-tide smell is shared by each, but they’re all different in essential ways—some are cold, others

Diamond-Studded Rock Contrasts Prevailing View of Early Solar System

A meteorite found in Egypt in 1996, deemed “Hypatia,” was recently further analyzed by researchers at the University of Johannesberg. In their published results, they found that due to a number of unusual compositional features—including high carbon content and unique

Under the Sea: Unusual Mantle Behavior

Under the Sea: Unusual Mantle Behavior

Though hidden, Earth’s interior is full of activity. Heat from Earth’s interior drives plate tectonics, the movement of giant slabs of the Earth’s crust. At certain areas, such as along the coast of Chile, one plate slides under another, sinking
