Low concentration CO2 can be reused in biodegradable plastic precursor using artificial photosynthesis
Osaka Metropolitan University scientists have developed a process using artificial photosynthesis to successfully convert more than 60% of waste acetone into 3-hydroxybutyrate, a material used to manufacture biodegradable plastic. The results were ob.....»»
Poor countries recycle far more imported plastic than previously thought—but it"s not enough
Countries like Malaysia import many metric tons of plastic waste from Europe each year, paying a few pennies per kilo. This might seem strange, but according to Kai Li, it makes sense......»»
Developing artificial muscles to give weakened people their strength back
Researchers have succeeded in making artificial muscle fibers from rubber thread, paving the way for sewing the muscles into a blouse and giving renewed strength to the wearer......»»
Study elucidates a mechanism for phosphorus cycling in subtropical forests
Phosphorus (P) is an important nutrient element in plant photosynthesis. However, the adsorption of mineral P via leaching and erosion leads to a decrease in P availability and consequently P deficiency......»»
Exxon Mobil says advanced recycling is the answer to plastic waste: But is it really?
When California Attorney General Rob Bonta filed suit against Exxon Mobil and accused the oil giant of misleading the public about the effectiveness of plastic recycling, many of the allegations surrounded the company's marketing of a process called.....»»
Designing multifunctional framework materials for sustainable photocatalysis
The goal of sustainable chemistry has motivated chemists to use renewable energy in chemical reactions, minimizing hazardous waste, and maximizing atom economy. Nature provides a blueprint with photosynthesis, in which carbohydrates are produced from.....»»
"We nicknamed it Eddy": What do schools and teachers think of AI in classrooms?
It's almost two years since ChatGPT burst onto the scene in late 2022. Since then, educators worldwide have been grappling with what generative artificial intelligence might mean for classrooms and learning......»»
Breathing may introduce microplastics to the brain—new study
Small plastic particles are everywhere: in the soil where our food is grown, in the water we drink and in the air we breathe. They got there from the plastic we throw away, which ends up in landfill sites, rivers and seas. There the plastic waste slo.....»»
How iron and metabolic constraints can aid gene discovery for photosynthesis and biofuel production
The single-cell green alga Chromochloris zofingiensis is an emerging model organism for photosynthesis and metabolism research. Previous research has shown that with the addition of glucose, Chromochloris zofingiensis shuts off photosynthesis, rerout.....»»
The unexpected role of magnetic microbes in deep-sea mining
Polymetallic nodules are potato-sized formations on the ocean floor that are rich in minerals such as nickel, cobalt, and manganese. Their concentration of rare, economically important minerals has made the nodules the focus of controversial deep-sea.....»»
Rethinking privacy: A tech expert’s perspective
Data privacy has become one of the most pressing challenges of our time, but it didn’t happen overnight. The proliferation of data collection, coupled with the rise of advanced technologies like artificial intelligence and machine learning, has.....»»
AI trained on evolution"s playbook develops proteins that spur drug and scientific discovery
A new artificial intelligence model developed by researchers at The University of Texas at Austin paves the way for more effective and less toxic treatments and new preventive strategies in medicine. The AI model informs the design of protein-based t.....»»
Key negotiator Norway sees "positive signals" ahead of plastic talks
In the single week that world leaders convened for high-level UN talks in New York, nearly 100,000 water bottles' worth of microplastics swirled through the city's air, posing known and still unknown risks to human health......»»
Do you feel eco-guilt or eco-shame? Emotions reveal how much we care about the environment
Air travel, meat in the shopping cart, waste sorting, plastic toys—consumers are faced with a barrage of everyday decisions and priorities when navigating environmental concerns. But what drives these choices?.....»»
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......»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
Spinning artificial spider silk into next-generation medical materials
It's almost time to dust off the Halloween decorations and adorn the house with all manner of spooky things, including the classic polyester spider webs. Scientists reporting in ACS Nano have made their own version of fake spider silk, but this one c.....»»
Researchers are commercializing technology to turn waste into plastic-free, biodegradable packaging
Seafood is a major industry in New England. It generates a lot of revenue for coastal communities, but with that productivity can come a lot of waste......»»
Study shows artificial light at night changes the behavior of fish, even into the next generation
Scientists have shown that light pollution—especially light in the blue spectrum—can alter the behavior of fish after only a few nights, and have knock-on effects for their offspring. The team from China has studied how female zebrafish responded.....»»
"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......»»
