Development of a new, non-invasive and topical sampling method uses low molecular weight, skin cancer biomarkers for better detection for early stages of skin cancer diagnostics.
Where is the calcium? First steps toward a new MRI brain-imaging technique
Calcium is important in bones and in brains. But which brain regions have a lot of calcium? Do disease states affect calcium levels? A new tool is being developed to find out.
More than just genes: looking for disease markers in methylated DNA
A tiny methyl group (one carbon bound to three hydrogen atoms) can be a big marker for disease.
Upcycling Plant Matter
Avocado peels and uprooted invasive plants can become a source for anti-inflammatories. I’ll toast to that!
MicroRNAs: A New Assay Searches for Targets
If your DNA is a cookbook of “recipes” your cells could make, microRNAs help decide what’s for dinner.
Looking for Viruses in Wild Bats
Cataloguing viruses in bats and other animals may help predict or trace viral transmission to humans in the future.
More than SPF: Some Common Sunscreen Ingredients to Avoid
Buying sunscreen? Take a look at the ingredients list first.
Polishing a Drug Lead: A Replacement for Opioids Reaches Clinical Trials
Many molecules can decrease enzymatic breakdown of our body’s natural painkillers…but which one is fit to be the best new drug?
Pathogenic E. coli Can Survive Stomach Acid…For Now
Infected cattle can transmit E. coli to humans through contaminated ground beef, but scientists are looking for a solution.
Harnessing bacteria to become royalty
Engineering bacteria to make the dye ‘royal purple’
The Smell of Rain Has a Biological Function
The earthy smell of soil originates from the bacteria that live there. But why do they produce this particular scent?
Unveiling cryptic compounds
How do you get microbes to produce cryptic compounds?
Biochemical Circuits: Modular Systems for Disease Detection
Instead of the wires, batteries, and light bulbs used in electric circuits, biochemical circuits use DNA and enzymes to get the job done.
Life in the Hot Springs: Bacterial Tricks for Thermal Stability
When cooking an egg, heat denatures proteins in the egg. How does a thermophilic bacteria prevent its proteins from denaturing too?
From Lead Pipes to Contaminated Drinking Water: Lead’s Chemical Accomplices
Lead pipes still exist in older infrastructure, but chemical water treatment can prevent (or increase!) the release of lead from the pipes to drinking water.
Better Antibiotics: Active in the Body, Degraded in the Environment
Antibiotics are lifesaving, but current practices don’t keep them from accumulating in the environment where they can damage nature and human health. A new antibiotic design aims to solve this problem.
Downstream Effects of Adding Hydrochar Nutrients to Soil
Thermochemical degradation of plant matter can create a great plant fertilizer called hydrochar. But what effect does this hydrochar have on the soil ecosystem?
Rapidly Developing Disease-Specific Detection Methods
Antibodies in your body help fight disease by specifically targeting a viral or bacterial strain. This specificity makes antibodies useful for disease detection, but how do scientists reduce the chance of false positives and false negatives?
How Long Do Nanoparticles Stay in the Body?
As nanotechnology is developed into drugs for human health, scientists need to study nanoparticle clearance rates from the body.
Enzymes Get Closer to Traditional Organic Chemistry – The Case of Reductive Amination
A clever, two-part biocatalytic strategy grants access to products of reductive amination that can be troublesome to obtain through more traditional synthetic methods.
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.
Is that molecule moving?
Scientists can now observe molecules vibrating
New Insights on The Elusive Protein Sulfinylation
Proteins bear a staggering collection of small chemical modifications that have large effects on their function. This research provides an elegant method to study cysteine sulfinylation, a chemical mark that has proven to be pretty elusive.
Chemistry and the cannon balls preservation
How can chemistry help preserve our cultural heritage?
Making computers from molecules – Molecular Turing Machines
In this article, explore the tiny molecules that could be used for computational work in future of smartphones! Inspired by your own body, machines made from molecules could be the next generation of computers!
