How do you destroy a forever chemical?
3M offers $10.3 billion settlement over PFAS contamination in water systems. What's next? Enlarge (credit: Andrew Brookes) PFAS chemicals seemed like a good idea at first. As Teflon, they made pots easier to clean starti.....»»
3D pattern generation via chemical vapor deposition of ceramic eutectic system for novel solid-state phosphors
The eutectic structure of metals and ceramics occurs when multiple solid phases solidify from a liquid phase, forming a three-dimensional (3D) pattern through a self-organizing phenomenon. Traditionally, it was believed that eutectic structures could.....»»

Reconstructing an alien astronomer"s view of our home galaxy"s chemistry
Researchers have reconstructed what alien astronomers observing our Milky Way galaxy from afar would find if they analyzed our home galaxy's chemical composition. The study, which is led by researchers from the Max Planck Institute for Astronomy, is.....»»
Stars collided in galactic “demolition derby,” produced oddball gamma-ray burst
Such oddball events tell astronomers a lot about spectacular diversity of cosmic explosions. Enlarge / Astronomers studying a powerful gamma-ray burst (GRB) may have observed a never-before-seen way to destroy a star. (credit: In.....»»
Stellar demolition derby births powerful gamma-ray burst
While searching for the origins of a powerful gamma-ray burst (GRB), an international team of astrophysicists may have stumbled upon a new way to destroy a star......»»
Rain gardens could save salmon from toxic tire chemicals
Specially designed gardens could reduce the amount of a toxic chemical associated with tires entering our waterways by more than 90 percent, new research shows......»»
Discovery of novel primitive xeno nucleic acids as alternative genetic polymers adds piece to origin of life puzzle
The chemical origin of life on Earth is a puzzle that scientists have been trying to piece together for decades. Many hypotheses have been proposed to explain how life came to be and what chemical and environmental factors on early Earth could have l.....»»
Understanding how chemical communication evolved in insects
All around us, insects are speaking to each other: jockeying for mates, searching for food, and trying to avoid becoming someone else's next meal. Some of this communication is easy to spot—like the flashes of fireflies on a summer night or a screa.....»»
Smart farming platform improves crop yields, minimizes pollution
A new farming system developed by researchers at The University of Texas at Austin aims to solve one of the biggest problems in modern agriculture: the overuse of fertilizers to improve crop yields and the resulting chemical runoff that pollutes the.....»»
Scientists develop inorganic resins for generating and purifying radium and actinium
Targeted alpha therapy can destroy cancerous cells without harming healthy cells. It's especially useful for treating metastasized cancers. The Department of Energy (DOE) Office of Science's Isotope Program is developing and marketing novel radioacti.....»»
Pheromone found to put scared rats at ease could lead to humane pest control
Some animals release chemical pheromones which can trigger behavioral or hormonal changes in other animals. It is known that calm rats can reduce fear in nearby rats, but the exact mechanism was unknown. Researchers, including those from the Universi.....»»
Opinion: To achieve climate neutrality in the chemical industry, we must also cut demand
Chemical products, such as plastics, fertilizers and solvents pervade our modern lifestyle. The vast majority are derived from crude oil or natural gas—and producing them generates around 5% of global CO2 emissions. To transition the chemical indus.....»»
Webb Telescope is powerful enough to see a variety of biosignatures in exoplanets, argues new paper
The best hope for finding life on another world isn't listening for coded messages or traveling to distant stars, it's detecting the chemical signs of life in exoplanet atmospheres. This long hoped-for achievement is often thought to be beyond our cu.....»»
Theoretical discovery: A new path for quantum physics to control chemical reactions
Controlling chemical reactions to generate new products is one of the biggest challenges in chemistry. Developments in this area impact industry, for example, by reducing the waste generated in the manufacture of construction materials or by improvin.....»»
New study reveals willingness of papaya farmers in Kenya to reduce pesticide use
A new study published in the CABI Agriculture and Bioscience journal has revealed a willingness of smallholder papaya farmers in Kenya to reduce their chemical pesticide use to fight the papaya mealybug (Paracoccus marginatus)......»»

Light and nickel found to simplify cross-coupling reactions
Cross-coupling reactions—chemical transformations in which two fragments are joined together—are a valuable tool in the synthesis of organic molecules. Applications range from drug development and synthesis of naturally occurring molecules to mat.....»»
Photosynthesis starts with a single photon, study shows
Using a complex cast of metal-studded pigments, proteins, enzymes, and co-enzymes, photosynthetic organisms can convert the energy in light into the chemical energy for life. And now, thanks to a study published June 14 in Nature, we know that this o.....»»
Retooling the ribosomal translation machine could expand chemical repertoire of cells
Synthetic biologists have become increasingly creative in engineering yeast or bacteria to churn out useful chemicals—from fuels to fabrics and drugs—beyond the normal repertoire of microbes......»»
