2023 Breakthrough Prize in Life Sciences for Anthony Hyman and Clifford Brangwynne

World’s largest science prize for discovering a new mechanism of cellular organization

23-Sep-2022

Anthony Hyman, the managing director of the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG), and Clifford Brangwynne, Professor of Chemical and Biological Engineering at Princeton University and Howard Hughes Medical Institute, have been honored with one of the three 2023 ...

Molecular networks serve as cellular blueprints

20-Apr-2020

Networks are at the heart of everything from communications systems to pandemics. Now researchers have found that a unique type of network also underlies the structures of critical cellular compartments known as membraneless organelles. These findings may provide key insights into the role of ...

Speed limit on DNA-making sets pace for life's first steps

15-Mar-2019

Fruit flies make for stingy mothers, imparting only a portion of the genetic building blocks their offspring need to survive. The rest must be produced by the fertilized egg in its first few steps of growth. Scientists puzzled for two decades over this seemingly unnecessary withholding. Now ...

For infection-fighting cells, a guideline for expanding the troops

Researchers at Princeton look into the mathematical relationship that describes how T cells expand in response to infection

13-Mar-2019

T cells are like the special ops forces of the immune system, detecting and killing infected cells. When a new threat is detected, the cells ramp up from just a few sentry cells to a full platoon. But how does the immune system make just the right amount of T cells, when the starting populations ...

Timing is key for bacteria surviving antibiotics

04-Jul-2018

For bacteria facing a dose of antibiotics, timing might be the key to evading destruction. In a series of experiments, Princeton researchers found that cells that repaired DNA damaged by antibiotics before resuming growth had a much better chance of surviving treatment. When antibiotics hit a ...

A factor important for ZIKA Virus host species restriction uncovered

21-Jun-2018

Princeton University researchers Qiang Ding, Alexander Ploss, and colleagues have identified one of the mechanisms by which ZIKA virus (ZIKV) circumvents immune control to replicate in human cells. In 2013, and again in 2015, the world witnessed devastating outbreaks of ZIKV, a hitherto obscure ...

Chemical coatings boss around bacteria, in the bugs' own language

01-Jun-2017

Princeton researchers have developed a way to place onto surfaces special coatings that chemically "communicate" with bacteria, telling them what to do. The coatings, which could be useful in inhibiting or promoting bacterial growth as needed, possess this controlling power over bacteria because, ...

Wave of the future

Terahertz chips a new way of seeing through matter

10-Feb-2017

Electromagnetic pulses lasting one millionth of a millionth of a second may hold the key to advances in medical imaging, communications and drug development. But the pulses, called terahertz waves, have long required elaborate and expensive equipment to use. Now, researchers at Princeton ...

Light powers new chemistry for old enzymes

23-Dec-2016

Enzymes are nature's tools for catalyzing life's essential reactions. Though unrivaled in their efficiency and selectivity, enzymes only carry out a narrow range of natural reactions, limiting their usefulness in modern organic synthesis. Now, Princeton researchers report a method that expands ...

The brain performs feats of math to make sense of the world

30-Aug-2016

Even if we find it difficult to calculate complicated probabilities on the spot, our brains constantly carry out these sorts of computations without our awareness -- and they're remarkably good at it. Princeton University researchers show in a new study how our brains combine complicated ...
