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.....»»
Examining the bio-impact of toxic chemical cocktails in the environment
Purdue University scientists are unraveling the complicated toxicity of a mixture of what are often called "forever chemicals" found in many consumer products......»»
Researchers measure magnetic field in eclipse medium of a spider pulsar PSR J2051-0827
Spider pulsars are a subclass of millisecond pulsar binary systems with low mass companions in short-period orbits. In spider pulsars, the pulsar wind and electromagnetic emission ablate and may destroy the companion......»»
Novel hydrogel finds new aptamers, or "chemical antibodies," in days
One double-helix strand of DNA could extend six feet, but it is so tightly coiled that it packs an entire sequence of nucleotides into the tiny nucleus of a cell. If that same DNA was instead split into two strands and divided into many, many short p.....»»
Constructing a global variable-resolution atmospheric physico-chemical coupling simulation framework
A research team led by Prof. Zhao Chun from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has developed a global variable-resolution modeling framework and conducted research using atmospheric sand.....»»
Researchers develop organic nanozymes suitable for agricultural use
Nanozymes are synthetic materials that mimic the properties of natural enzymes for applications in biomedicine and chemical engineering. Historically, they are generally considered too toxic and expensive for use in agriculture and food science. Now.....»»
Paving a way to green hydrogen production
A sustainable route to green hydrogen production is becoming possible through the use of efficient electrocatalysts in research by Texas A&M University chemical engineering professor Dr. Abdoulaye Djire......»»
Local chemical pressure experimentally sensed by optical probe
The practical application of high-pressure metastable materials is hindered by severe synthesis condition, poor yield, and mostly vanishing phase and phenomena after decompressing. The scaled-up capture of these metastable states to ambient pressure.....»»
Material cycle for amine chemistry: Important building blocks created from platform chemical in single step
Fossil raw materials still dominate the chemical industry. But laboratories around the world are researching ways in which large-scale processes can avoid crude oil, natural gas and coal in the future. So-called platform chemicals are gaining in impo.....»»
This Dyson-style cordless vacuum is $100 for Prime Day
The BISSELL PowerGlide 3080 is an incredible way to destroy pet hair in your home. It's on sale now for Prime!.....»»
Increase in forest fires may damage the crucial ozone layer
All particles that reach the atmosphere cause different chemical reactions. Particles come partly from natural sources such as volcanic eruptions and forest fires, and partly from pollution and emissions. Aerosol researcher Johan Friberg studies part.....»»
How phytochemical diversity affects herbivore damage in a tropical tree community
Recent advances in metabolomics are improving our understanding of the ecological impacts of plant chemical diversity. However, few studies have examined how phytochemical diversity affects herbivore damage at the community scale in tropical tree com.....»»
Scientists upcycle polyesters through new waste-free, scalable process
Researchers from Tokyo Metropolitan University have developed a new chemical process which upcycles polyesters, including PET in plastic bottles, to morpholine amide, a versatile and valuable building block for synthesizing a vast range of compounds......»»
Scientists build a spatial atlas of the chloroplast proteome, the home of photosynthesis
Plants and algae convert solar energy into chemical energy through photosynthesis. This process is vital for life on Earth and provides us with oxygen, food, fuels, and other valuable products. Photosynthesis occurs inside the cells, in structures ca.....»»
“Real Water” that poisoned dozens contained chemical from rocket fuel
An expert witness testified hydrazine was likely formed during an electrolysis process. Real Water sold in jugs. (credit: FDA) A jury this week awarded $228.5 million to seven plaintiffs in their case against Nevada-base.....»»
Jury awards $229M to victims of “Real Water” tainted with rocket fuel chemical
An expert witness testified hydrazine was likely formed during an electrolysis process. Real Water sold in jugs. (credit: FDA) A jury this week awarded $228.5 million to seven plaintiffs in their case against Nevada-base.....»»
Researchers catch protons in the act of dissociation with ultrafast "electron camera"
Scientists have caught fast-moving hydrogen atoms—the keys to countless biological and chemical reactions—in action......»»
New pipeline makes valuable organic acid from plants—saving money and emissions
In a breakthrough for environmentally friendly chemical production, researchers at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) have developed an economical way to make succinic acid, an important industrial chemical, from sug.....»»
New species of cobra-like snake discovered, but it may already be extinct
Around the world, natural history museums hold a treasure trove of knowledge about Earth's animals. But much of the precious information is sealed off to genetic scientists because formalin, the chemical often used to preserve specimens, damages DNA.....»»
Using DNA as glue to hold nanostructures together and build ultra-strong colloidal crystal metamaterials
A team of chemical and biological engineers working with a group of nanotechnologists at Northwestern University in Illinois has developed a type of super-strong colloidal crystal metamaterial by gluing together metal nanostructures using strands of.....»»
Saturday Citations: Volcano vs. asteroid; NASA"s supernova time lapse; immortal chemicals
This week, we're highlighting a study involving toxic chemical contaminants, and just for fun, a second study involving other toxic chemical contaminants. But NASA made a cool time-lapse video using the good old Hubble space telescope, and a group of.....»»
