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.
Antibiotics in our food?
Antibiotics are all something we have all taken at one point or another – but how many of us wonder about what happens to those antibiotics next? When we stop and think about it, we might start to realise how our actions are unintentionally impacting the environment around us.
How God views Chemistry is ultra cool!
The world which we perceive is governed by the laws of classical mechanics. Whereas when we bring down the temperature conditions of a reaction to the ultracold regime, we start appreciating the reactions’ true nature.
Science of Soot
A new look on the chemistry occurring inside a flame!
Molecular tweezers pick viral membranes apart
While most scientists search for specific treatments for viruses like Ebola, Zika and SARS-Cov-2, non-specific methods can have broad impact. Researchers from the United States and Germany joined forces to make non-specific molecular “tweezers” that pluck pieces out of its membrane, leading to disintegrating and dead viruses.
Boiling mulberry juice increases its anti-cancer properties
Black mulberry juice is a known antioxidant – compounds that can consume free radicals before they can harm your cells. Researchers at Guangdong University also show that boiling mulberries increases its ability to treat colon cancer in cell culture, but not through antioxidant mechanisms.
#BlackInChem: Creating Support and Community for Black Women in STEM
Devin Swiner, one of the founders for #BlackInChem, shares what’s she’s learned, the hard-won wisdom she has earned as a Black woman in analytical chemistry.
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.
Monitoring Vital Signs with Temporary Tattoos
Skin-conforming, ultra-thin wearable medical sensors could make going to the doctor less invasive than ever before. This newly developed, “tattooable” sensor uses a newly developed material to create one of the thinnest yet.
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?
Monitoring plant maturation with a Wack reaction
When the authors’ blurb about their own work is “Okay, bloomer,” you know you have to read it.
Catching it Early: New Ways of Detecting Coronavirus
Coronavirus has affected every one of us directly or indirectly. Early detection can lower the spread of the disease. Let’s learn about a new technique for rapid detection of SARS-CoV-2, the virus responsible for COVID-19.
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.
Road Salt Impacts the Atmosphere
A surprising new source of chlorine to the atmosphere: road salt!
How effective are fabric masks?
The COVID-19 global pandemic has affected nearly every aspect of our lives, including the daily use of face masks. But how well do home-made fabric masks really filter the air we breathe?
What a shock: material changes can impact charge
The amount of charging on an object changes when it is folded or unfolded.
Discovery of a New Ozone Depleting Substance in the Atmosphere
The first complete iodine measurements in the middle atmosphere detected higher levels than expected.
Vanilla substitute loosens up cell membranes to increase drug uptake
Could vanillin, the flavoring molecule extracted from vanilla bean, increase our body’s ability to absorb ingested drugs?
Chemistry of Photography: How Veiled Photographs are Made
Mordançage is a photography technique that has been used by artists for decades, but only recently have researchers discovered the chemistry behind the process.
Development of Sensors for Amino Acids
Researchers develop an easy to use method to identify the chirality of the amino acids, amines and alcohols.
A fifty-year-old question about molecular structure answered with a picture
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!
