What does a ring of 18 carbon atoms look like? An atomic scale image settles the debate.
More than just our genetic code: how chemical modifications affect gene expression
DNA is the instruction manual for how to produce an organism, one gene at a time. But our heart cells, liver cells, and brain cells are different, despite having the same DNA, thanks in part to the “epigenetic” modifications that control which genes are expressed.
Light me up: can visible light impact forensic luminol reactions?
Crime scene techs use luminol to reveal latent bloodstains – can normal, visible light increase the reaction’s sensitivity?
Smelling chemicals with an artificial nose
Nothing compares to a well-trained dog’s nose for smelling out faint odors. But a new artificial nose made with living cells may come close!
Scientists Are Now Shooting Lasers at Historic Art
What do lasers and the Mona Lisa have in common? Well, it turns out scientists can use lasers to help save old paintings from degrading, preserving our masterpieces for future generations. Pump-probe microscopy is one such technique.
Is that molecule moving?
Scientists can now observe molecules vibrating

What’s In A Screen? Improving Charge Transfer in Quantum Dot Films
What’s in a screen? It might be tiny particles called quantum dots – a novel material for everything from screens to solar cells. But how do researchers optimize new materials like quantum dot films? One type of spectroscopy – called transient absorption – could help.
Skeletons tell Stories– Chemistry of the burned bones!
Happy Halloween Everyone! In this article, we are going to honor the dead and discuss their stories and also learn to communicate with them using analytical chemistry techniques. Explore with me the power of infrared spectroscopy and walk down the memory lane with the skeletons!
The influence of one water molecule on the gas-phase structure of triglycine
Can one water molecule change the conformation of a peptide? Vibrational spectroscopy in the gas-phase is the perfect technique to answer this question.
What can you do with a glucose meter?
More than you might think! Researchers have “hacked” glucose meters to detect enzymes, bacteria, and viruses using a device millions of people already use every day.
Chemistry, archaeology and the ergot fungi: solving the mystery of the past
During thousands of years of burial, cereals from ancient artifacts are degraded and consumed, but ergot fungi produce a fingerprint of lipids that we can use to trace them.
Proteomics Aids a Cheesy Discovery in Ancient Egypt
What can we learn when anthropology and chemistry join forces? Analytical chemists used proteomics to study the world’s oldest cheese sample discovered in an ancient Egyptian tomb.
