Pepsin-degradable plastics of bio-nylons from itaconic and amino acids
Currently available conventional nylon such as nylon 6, nylon 66, and nylon 11 are nondegradable. On the other hand, bio-nylons derived from itaconic acid showed higher performance than conventional ones and are degradable in soil, but degradability.....»»
Unique IDs for individual (digital) specimens from natural history museums streamline and future-proof science
The wealth of data hosted in natural history collections can contribute to finding a response to global challenges ranging from climate change to biodiversity loss to pandemics. However, today's practices of working with collected bio- and geodiversi.....»»
Wastewater bacteria can break down plastic for food, yielding new possibilities for cleaning up plastic waste
Researchers have long observed that a common family of environmental bacteria, Comamonadacae, grow on plastics littered throughout urban rivers and wastewater systems. But exactly what these Comamonas bacteria are doing has remained a mystery......»»
Synthetic modules boost production of animal-based nutrients in plants
It's important to eat your veggies, but some essential vitamins and nutrients can only be found in animals, including certain amino acids and peptides. Now, in a proof-of-concept study published in the Journal of Agricultural and Food Chemistry, rese.....»»
Scientists find plausible geological setting that may have sparked life on Earth
Researchers have discovered a plausible evolutionary setting in which nucleic acids—the fundamental genetic building blocks of life—could enable their own replication, possibly leading to life on Earth......»»
Researchers use carbon nanotube derivatives to strengthen recyclable plastics
Reducing the environmental impact caused by plastics can be addressed through different strategies, such as the manufacture of more durable plastics or recycling. In general, there are two main types of plastics. The first is thermoplastics, which ca.....»»
Citizen scientists help discover microplastics along the entire German coastline
The global production of plastics and the resulting plastic waste has increased to such an extent that plastics have become ubiquitous in our environment. Plastics of various sizes are also found along the German North Sea and Baltic coasts......»»
"Convergence" growing on global plastics treaty: UN environment chief
The UN environment chief said Sunday she was beginning to see convergence on the world's first binding treaty on plastic pollution despite differences on production caps and a tax-like plastic fee......»»
Vaporizing plastics recycles them into nothing but gas
Polypropylene and polyethylene can be broken down simultaneously. Enlarge (credit: Derek Berwin) Our planet is choking on plastics. Some of the worst offenders, which can take decades to degrade in landfills, are polypro.....»»
Plastics: navigating the maze of dizzying acronyms
Plastics are all around us—from food packaging and drinking bottles to the insulation in our homes......»»
CRISPR/Cas9 modifies Euglena to create potential biofuel source
News about biofuels sometimes mentions used cooking oil as a feedstock, but if these substances contain animal fat, they can solidify in colder temperatures. This happens because, chemically, the fatty acids of these and many other saturated fats hav.....»»
Team develops new tool to map fossil fuel emissions from space
University of Minnesota researchers have developed a new tool to measure ethane from space, leading to a better understanding of fossil fuel emissions worldwide. Ethane is commonly found in natural gas and is primarily used in plastics manufacturing......»»
Zeolite catalyst method uses microwaves to convert waste cooking oil into useful chemicals
Researchers from Kyushu University have revealed that a zeolite material called Na-ZSM-5 is effective in improving the chemical conversion of biomass into olefins—a precursor chemical that makes everything from plastics to pharmaceuticals—using m.....»»

Greenpeace sounds alarm on microplastics ingested by Hong Kong wildlife
Microplastic particles turned up in the vast majority of waste samples taken from Hong Kong wildlife in a Greenpeace study, the group said Monday, suggesting that animals still ingest plastics even if they are not feeding in urban areas......»»
Glitch in protein synthesis could affect tumor growth
During protein synthesis, or translation, genetic information transcribed in the cell's mRNA directs the stringing together of amino acids—the building blocks of proteins. As the translation machinery carouses along the string of nucleotides that m.....»»
Catalytic process vaporizes plastic bags and bottles, yielding gases to make new, recycled plastics
A new chemical process can essentially vaporize plastics that dominate the waste stream today and turn them into hydrocarbon building blocks for new plastics......»»
Compounds from nucleic acids in food show anticancer effects
When people eat, they ingest the nucleic acids that reside in all living things. The compounds in these acids could inhibit the growth of cancer cells, according to findings published in PLOS ONE by Osaka Metropolitan University Associate Professor A.....»»
Experts meet as final global plastic treaty talks near
With months until crunch talks on the world's first binding treaty on plastic pollution, experts are meeting in Bangkok to discuss financing options and problematic plastics......»»
Researchers identify effective materials for protecting astronauts from harmful cosmic radiation on Mars
Researchers have identified specific materials, including certain plastics, rubber, and synthetic fibers, as well as Martian soil (regolith), which would effectively protect astronauts by blocking harmful space radiation on Mars. These findings could.....»»
Coaxing purple bacteria into becoming bioplastic factories
In a world overrun by petroleum-based plastics, scientists are searching for alternatives that are more sustainable, more biodegradable and far less toxic to the environment......»»
