A new catalyst that transforms carbon dioxide into added-value chemical products
Global warming is an increasingly worrying problem. Although the greenhouse effect is a necessary process to maintain living conditions on Earth, our current societies are increasing the emission of greenhouse gases into the atmosphere and increasing.....»»
Fish-on-Chips: An optofluidic platform to investigate the neural and chemosensory axes of zebrafish
Neuroscientists study chemosensory processing by establishing chemical cues and the corresponding behavioral responses to record large-scale neuronal activity. In a new report now published in Nature Communications, Samuel Sy and a team of scientists.....»»
Town where child cancer rose blasts deal over polluted site
In hindsight, it's clear that something was very wrong in this suburban town at the Jersey Shore, where many people worked at or lived near a chemical company that was flushing toxic waste into waterways and burying it in the ground......»»
California wants to ban the toxic chemical that gives chrome its classic shine
For decades, hexavalent chromium has provided the silvery showroom finish to countless consumer products, from automobile bumpers and grilles to kitchen faucets and light fixtures. It has also served as an indispensable rust-resistant coating for avi.....»»
Plant protection of the future may come from the plants themselves
Humans and animals all have chemical and microbial signatures that influence their well-being in one way or another. In medicine, the use of probiotics rather than antibiotics has become high on the agenda. However, humans and animals are not the onl.....»»
What happens to drugs after they leave your body?
Swallowing a pill only seems to make it disappear. In reality, the drug eventually leaves your body and flows into waterways, where it can undergo further chemical transformations. And these downstream products aren't dead in the water......»»
An overview of the 30-year history of metabolic engineering
A research team comprised of Gi Bae Kim, Dr. So Young Choi, Dr. In Jin Cho, Da-Hee Ahn, and Distinguished Professor Sang Yup Lee from the Department of Chemical and Biomolecular Engineering at KAIST have summarized the 30-year history of metabolic en.....»»
An online tool can help researchers synthesize millions of molecules
Enzymes are substances that cause chemical reactions. Certain types of enzymes, such as polyketide synthases and nonribosomal peptide synthetases, have the ability to shuffle their parts, allowing them to produce new chemicals. If scientists can unde.....»»
The world’s farms are hooked on phosphorus, and that’s a problem
Nonrenewable fertilizer powers 50% of Earth's agricultural productivity. Enlarge (credit: Brian Brown/Getty Images) Disrupting Earth’s chemical cycles brings trouble. But planet-warming carbon dioxide isn’t the only.....»»
Micelles—the meeting place boosting reactions and interactions
The occurrence of chemical reactions between like-charged compounds in aqueous solutions is very slow since particles repel each other. A recent breakthrough published in Nature Communications shows a new way to control chemical reactions by charge n.....»»
"Rubble pile" asteroids nearly impossible to destroy, study suggests
Curtin University-led research into the durability and age of an ancient asteroid made of rocky rubble and dust, revealed significant findings that could contribute to potentially saving the planet if one ever hurtled toward Earth......»»
Virus plus microplastics equal double whammy for fish health
Microplastics—tiny particles generated as plastics weather and fragment—pose a growing threat to ecosystem and human health. A new laboratory study shows these threats extend beyond direct physical or chemical impacts, revealing that the presence.....»»
D&D maker still wants to revoke earlier versions of “open” gaming license
Core rules would go under Creative Commons, "hateful" content would be barred. Enlarge / Artist's conception of D&D-maker Wizards of the Coast trying to destroy its original Open Gaming License with fire. (credit: Lego / WotC).....»»
Using cancer cells as logic gates to determine what makes them move
Cancer cells migrate through the body for multiple reasons; some are simply following the flow of a fluid, while others are actively following specific chemical trails. So how do you determine which cells are moving and why? Purdue University researc.....»»
How was the solar system formed? The Ryugu asteroid is helping us learn
Mineral samples collected from the Ryugu asteroid by the Japan's Hayabusa2 spacecraft are helping UCLA space scientists and colleagues better understand the chemical composition of our solar system as it existed in its infancy, more than 4.5 billion.....»»
Researchers unravel the complex reaction pathways in zero carbon fuel synthesis
Photosynthesis is the natural process of converting carbon dioxide (CO2) to useable chemical compounds. In contrast, carbon capture and utilization technologies through processes such as electrochemical CO2 reduction (eCO2R) are the man-made equivale.....»»
Biomolecular analyses now have an expanded chemical toolkit
The 2022 Nobel Prize in Chemistry was awarded in part for what can be a quite difficult problem: precisely altering one aspect of biomolecules without affecting the rest of the cell. Now, in a study recently published in Organic Letters, researchers.....»»
Chemical navigation: Scientists develop a water remediation method using nanoparticles
Chemists from St Petersburg University have developed a method for purifying water from organic compounds using tin oxide nanoparticle based photocatalysts. The findings of the research are published in the Journal of Alloys and Compounds ......»»
Chemical isotopes from plant xylem can improve representations of the forest water cycle
Plants are an integral part of the water cycle. Certain plant traits, like rooting depth and water storage, can govern water availability across an entire ecosystem......»»
Building better catalysts to close the carbon dioxide loop
The best way to stave off the worst effects of climate change is to reduce CO2 emissions around the world. And one way to do that, says Zhongwei Chen, a professor in the Department of Chemical Engineering at the University of Waterloo, is to capture.....»»
