In April 2020, as microbiologist Cameron Myhrvold had just finished his second interview to join Princeton’s faculty, his paper was published in Nature introducing the revolutionary CARMEN system that simultaneously tests for the 170 most prevalent human-infecting viruses — including the then-novel coronavirus. At the time, only 39 of those…

Princeton team discovers new organelle involved in cancer metastasis

Written by Liz Fuller-Wright, Office of Communications

Some of Princeton’s leading cancer researchers were startled to discover that what they thought was a straightforward investigation into how cancer spreads through the body — metastasis — turned up evidence of liquid-liquid phase separations: the new field of biology research that investigates how liquid blobs of living materials merge into…

How we can use psychological principles to foster collaboration in the fight against COVID-19

COVID-19 can be thought of as a game of chicken, except instead of driving head-on towards each other and betting the other person will swerve at the last minute, we’re going out when we should be staying home and foregoing social distancing, masks and hygiene measures.

“If we can rely on other people to follow the rules, we can get…

The Howard Hughes Medical Institute (HHMI) has named Princeton postdoctoral researcher Sofia Quinodoz a 2020 Hanna Gray Fellow, bolstering her study into how the structures within cells contribute to disease.

Quinodoz will receive up to $1.4 million over…

True toll of coronavirus on sub-Saharan Africa may be obscured by tremendous variability in risk factors and surveillance

Written by Morgan Kelly, High Meadows Environmental Institute

One early feature of reporting on the coronavirus pandemic was the perception that sub-Saharan Africa was largely being spared the skyrocketing infection and death rates that were disrupting nations around the world.

While still seemingly mild, the true toll of the novel coronavirus, SARS-CoV-2, on the countries of sub-Saharan Africa…

Scientists and research based at Princeton University played a critical role in a new national report that investigates the technology, policy and societal dimensions of accelerating decarbonization in the United States.

On Feb. 2, the National Academies of Sciences, Engineering, and Medicine published the interactive report, “

Dewdrops on a spiderweb reveal the physics behind cell structures

Written by Caitlin Sedwick for the Department of Molecular Biology

As any cook knows, some liquids mix well with each other, but others do not.

For example, when a tablespoon of vinegar is poured into water, a brief stir suffices to thoroughly combine the two liquids. However, a tablespoon of oil poured into water will coalesce into droplets that no amount of stirring can dissolve. The physics that…

Mange in Yellowstone wolves reveals insights into human scabies and conservation biology

Author
Written by Liana Wait, Department of Ecology and Evolutionary Biology

Before wolves were reintroduced to Yellowstone National Park in the mid-1990s, they were vaccinated for common diseases and treated for any parasite infections they already carried. As a result, the first few generations of wolves were relatively disease-free, but over the years, various diseases have found their way into the population. 

Social bacteria build shelters using the physics of fingerprint patterns

Written by Catherine Zandonella, Office of the Dean for Research

Forest-dwelling bacteria known for forming slimy swarms that prey on other microbes can also cooperate to construct mushroom-like survival shelters known as fruiting bodies when food is scarce. Now a team at Princeton University has discovered the physics behind how these rod-shaped bacteria, which align…
