Dinosaurs lived relatively long lives. The oldest Tyrannosaurus rex specimens that we’ve found were alive for about 30 years. It’s likely that many dinosaurs, especially sauropods, lived much longer than that. And with long lives and aging comes diseases. But what do we know, and what can we know about the diseases that impacted our favorite dinosaur species?According to Penélope Cruzado-Caballero, an assistant professor of paleontology at the University of La Laguna in Spain, dinosaurs ...read more
There’s no way to sugarcoat it: Animal and plant life is declining across the globe at rates never seen before in human history. And alongside this decline, extinction rates are speeding up — as many as one million plant and animal species are at risk of being lost forever, according to a landmark United Nations report in 2019.What’s more, humans may be uniquely responsible for fueling these losses. Activities like agriculture and aquaculture are changing the habitats of animals at an “u ...read more
The weekends just don’t feel long enough. On Fridays, you’re exhausted from a long work week. Saturdays are for running around doing errands that you weren’t able to get done on the weekdays.

Here’s why you’re getting the Sunday Scaries an ...read more

While once hotly debated, this observational reality now forms the bedrock for our modern conceptions of the cosmos.The first evidence for an expanding universe came through Albert Einstein’s discovery of the general theory of relativity in 1917. Other scientists have since gathered more evidence, and expanded his ideas into more tangible models.Einstein's Expanding UniverseEinstein’s t ...read more
These days, we're accustomed to seeing very high resolution satellite images revealing the horrifying impact of extreme weather. Below, I offer a particularly dramatic example: before and after images of the destruction wrought by a tornado — one of at least 20 in an outbreak across the South — that ravaged Rolling Fork, Mississippi on March 24, 2023.But I was struck even more by the broader perspective seen in the image above, published by NASA. Instead of a relatively close up view of home ...read more
