Plastic-eating fungi thriving in man-made ‘plastisphere’ may help tackle global waste

Year 2023 😗 😁


A new study published in the Journal of Hazardous Materials by researchers at the Royal Botanic Gardens, Kew, and partners has identified a diverse microbiome of plastic-degrading fungi and bacteria in the coastal salt marshes of Jiangsu, China.

The international team of scientists counted a total of 184 fungal and 55 bacterial strains capable of breaking down polycaprolactone (PCL), a biodegradable polyester commonly used in the production of various polyurethanes. Of these, bacterial strains within the genera Jonesia and Streptomyces have the potential to further degrade other petroleum-based polymers—natural or synthetic chains of molecules bound together.

The plastic-degrading microorganisms were sampled in May 2021 from Dafeng in eastern China, a UNESCO-protected site near the Yellow Sea Coast. The sampling confirmed the presence of a terrestrial plastisphere, a term that is relatively new to terrestrial ecology as past studies have primarily focused on marine environments. The microbiome of this “man-made ecological niche” of coastal plastic debris was further found to be distinct from the surrounding soil.

Lucid cuts prices by up to $8000 to attempt to surge demand

Lucid has cut prices on the Air electric vehicle lineup by as much as $8,000 in an attempt to surge demand.

The Lucid Air Pure Rear-Wheel-Drive is now priced at $69,900. The most affordable and accessible trim of the Air features a sleek interior and exterior design and a driving range of up to 410 miles. It was previously priced at $77,400.

The Lucid Air Touring is now priced at $77,900 and features an All-Wheel-Drive powertrain that produces 620 horsepower. It was previously $85,900.

Ecosystem Under Siege: An Alien Invasion That Could Trigger Catastrophic Changes Is Underway Across North America

An alien invasion capable of triggering catastrophic changes is underway across North America. At least 70 imported earthworm species have colonized the continent, and represent a largely overlooked threat to native ecosystems, according to a new study by researchers at Stanford University, Sorbonne University, and other institutions.

The analysis, recently published in the journal Nature Ecology & Evolution, provides the largest-ever database of such earthworms and warns of the need to better understand and manage the invaders in our midst.

“Earthworms tell the story of the Anthropocene, the age we live in,” said study senior author Elizabeth Hadly, the Paul S. and Billie Achilles Professor in Environmental Biology in the Stanford School of Humanities and Sciences. “It is a story of global homogenization of biodiversity by humans, which often leads to the decline of unique local species and the disruption of native ecosystem processes.”

Harnessing light with hemispherical shells for improved photovoltaics

In the pursuit of sustainable energy solutions, the quest for more efficient solar cells is paramount. Organic photovoltaic cells have emerged as a promising alternative to traditional silicon-based counterparts due to their flexibility and cost-effectiveness. However, optimizing their performance remains a significant challenge.

In a pioneering move, new research from Abdullah Gül University (Türkiye) reimagines the structure of organic photovoltaic cells, opting for a hemispherical shell shape to unlock unprecedented potential in and angular coverage.

As reported in the Journal of Photonics for Energy, this innovative configuration aims to maximize light absorption and angular coverage, promising to redefine the landscape of renewable energy technologies. The study presents advanced computational analysis and comparative benchmarks to spotlight the remarkable capabilities of this new design.

Tesla is now accounting for ‘battery age’ in its range calculation

Tesla is now starting to account for “battery age” in its estimated range calculation for its electric vehicles.

I have long been advocating for prioritizing accurate range prediction over a longer range in curbing range anxiety.

Don’t get me wrong, a longer range can be useful, but if you know what where you are going, the main thing is that you know you can get there and your range doesn’t start dropping faster than anticipated.
