Tamara Pico, a postdoctoral fellow, is using records of flooding in the Bering Strait to make inferences about how the ice sheets that covered North America responded to the warming climate, and how their melting might have contributed to climate changes.

An analysis of 20 butterfly genomes found evidence that many butterfly species — including distantly related species — show a surprisingly high amount of gene flow between them, Harvard researchers found.

Using precisely focused lasers that act as “optical tweezers,” Harvard scientists have been able to capture and control individual ultracold molecules – the eventual building-blocks of a quantum computer – and study the collisions between them in more detail than ever before.

Samuel Mehr has long been interested in questions of what music is, how music works, and why music exists. To help find the answers, he’s created the Music Lab, an online, citizen-science project aimed at understanding not just how the human mind interprets music, but why music is a virtually ubiquitous feature of human societies.

Study shows that students learn more when taking part in classrooms that employ active-learning strategies
A new Harvard study shows that, though students felt like they learned more from traditional lectures, they actually learned more when taking part in active-learning classrooms.

Martin Haesemeyer set out to build an artificial neural network that worked differently than fish’s brains, but what he got was a system that almost perfectly mimicked the zebrafish — and that could be a powerful tool for understanding biology.
