You’d be in bad shape if your cells couldn’t fix DNA issues that arise.
Cells must repair the thousands of bits of DNA damage they incur every day. These cellular mechanisms fend off cancerous tumors, and cancer researchers are working to harness their power.
Tomas Lindahl, pictured here in the lab, along with Paul Modrich and Aziz Sancar, received the Nobel Prize for Chemistry.
The recipients of this year's Nobel Prize for Chemistry showed that DNA is far from static. Rather, it is bombarded by damaging forces, but our bodies know how to repair these precious strands.

The 2015 Nobel Prize for Medicine went partly for research done during the Chinese Cultural Revolution based on traditional Chinese medicine. Here's the story of Project 523.
Never before has a Nobel gone to an expert in traditional Chinese medicine.
The first Chinese Nobel Prize in medicine was awarded for work based on traditional Chinese medicine. Will traditional medical knowledge now share the spotlight with evidence-based medicine?

Stephens’ banded snake is one of Australia’s few arboreal (tree-dwelling) venomous snakes.
Most people avoid venomous creatures, but they can also teach us a lot about chemical reactions that take place outside of the body - or exochemistry.
Smells good – but how does it work?
New research couldn't find evidence for a controversial theory of how our sense of smell works.

Fluorescent security ink produces multicolor barcode visible under UV light.
Invisible under normal light but fluorescent under UV light, this ink can print out unique signatures that use 'molecular encryption' to authenticate anything they tag.

Mass spectrometry will identify those explosive molecules.
You’ve probably had your hand luggage swabbed after walking through the metal detector at the airport. Whatever molecules were picked up by the swab have been separated using gas chromatography. So how…
You have gas chromatography and mass spectrometry to thank for keeping you safe from explosives in air travel.
As the holidays draw near, many of us will hop on a plane to visit friends and family – or just get away from it all. Some will be subjected to a swab at the airport to test clothes and baggage for explosives…
