Since 2011, enormous seaweed blooms have spread across the Atlantic Ocean, spanning over 5,000 miles from West Africa to the Gulf of Mexico.

Known as the Great Atlantic Sargassum Belt, the leviathan — visible from space — has wreaked havoc on environments and economies throughout the Caribbean Sea and Gulf of Mexico, where unprecedented…

‘A history of contact’: Princeton geneticists are rewriting the narrative of Neanderthals and other ancient humans

Ever since the first Neanderthal bones were discovered, people have wondered about these ancient hominins. How are they different from us? How much are they like us? Did our ancestors get along with them? Fight them? Love them? The recent discovery of a group called Denisovans, a Neanderthal-like group who populated Asia and Oceania, added its…

Pouring cream into coffee creates a show of eddies that rivals Jupiter’s roiling storms. But one clank of the spoon collapses all that black and tan chaos into a smooth, uniform brown.

It turns out there’s a lot to that mixing. For one thing, industries rely on robust mixing processes to make all kinds of material goods…

Imagine it’s flu season, and that tickle in the back of your throat has turned into symptoms bad enough to drive you to visit your doctor. Your physician would ideally run some tests to diagnose what pathogen is afflicting you, but unless they are at a large hospital, they may not have access to the complicated, costly tests they need. That’s…

In a funding venture that could be transformational for imaging single molecules within a cell, the Gordon and Betty Moore Foundation has awarded a $3.4M grant to a collaboration between Princeton’s Departments of Chemistry and Molecular Biology.

The four-year grant supports the development of a new microscope that will enable researchers…

How eavesdropping viruses battle it out to infect us

Written by Liz Fuller-Wright, Office of Communications

Viruses, like movie villains, operate in one of two ways: chill or kill.

They can lie low, quietly infiltrating the body’s defenses, or go on the attack, making many copies of themselves that explode out of hiding and fire in all directions. Viral attacks are almost always suicide missions, ripping apart the cell that the virus has been…

Written by Wendy Plump, Department of Chemistry

Studying the microbiology of any entity, be it a molecule or a dolphin, ideally means putting a spotlight as close to the source material as possible. That can be especially challenging when you’re investigating the Rube Goldberg environment of a cell’s nucleus.

But in research published this week in Nature, Princeton chemists…

More possible entry points for COVID spike protein identified by Princeton scientists

Author
Written by Wendy Plump, Department of Chemistry

One of the essential factors the COVID-19 virus needs to enter a host is a receptor on a human cell — a place where the universally recognized spike protein can latch onto the cell surface, pierce it, disgorge its infectious contents, and replicate.

Without a receptor, there is no replication. Without replication, there is no infection…
