Researchers advance new route to chemically recyclable plastics

As the planet's burden of rubber and plastic trash rises unabated, scientists increasingly look to the promise of closed-loop recycling to reduce waste. A team of researchers at Princeton's Department of Chemistry announces ...

Researchers report role of quantum vibrations in electron transfer

Princeton Chemistry's Scholes Group is reporting evidence that quantum vibrations participate in electron transfer, establishing with ultrafast laser spectroscopy that the vibrations provide channels through which the reaction ...

What caused the ice ages? Tiny ocean fossils offer key evidence

The last million years of Earth history have been characterized by frequent "glacial-interglacial cycles," large swings in climate that are linked to the growing and shrinking of massive, continent-spanning ice sheets. These ...

Social bacteria build shelters using the physics of fingerprints

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 ...
