Philadelphia Spanish speakers break traditional rules of formal and informal speech with signs around town
The Spanish signs of Philadelphia contradict the grammatical lessons that most of us have been taught. Credit: Daniel Guarin Buitrago, CC BY-ND I have found fascinating about how Philadelphia Spanish speakers deal with each other and communicate through public indications. This finding is part of my research on Philadelphia language patterns, challenging what many students have learned in Spanish classes.…

Earth’s hidden carbon recycling: Sulfur bacteria work together to break down organic matter from the seabed
To determine the molecular tools sulfate-reducing bacteria use, researchers analyzed the entire set of proteins known as the proteome. In total, they looked at the results of 80 different test conditions. Each time, the protein mixture was separated in several steps until individual compounds were identified. Here, a separation gel containing a blue band with proteins of similar size and…

Light triggering processes break down polymers into monomers and make recycling easier
The return of commercially available plexiglass to the starting material, the monomers. Credits: Hyun Suk Wang and Athina Anastasaki A team of materials scientists and engineers from Eth Zurich have developed a light chemical process to break down specific polymers into component monomers. This paper has been published in Journal Science. In recent years, scientists have noticed new problems associated…

Powerful marine fungi can eat it and break down plastic and condition it to make it faster
A variety of colorful marine bacteria grown in Anthony revised Lab Petri cuisine. Credit: Syrena Whitner at the University of Hawaii Plastics are the most common marine pollutants, and plastic surfaces are the fastest growing habitat in the ocean. Researchers at the University of Hawaii in Manoa (Um) recently discovered that many species of fungi isolated from Hawaii’s near waters…

The first major chunks break away from the world’s largest iceberg
The world’s largest iceberg was almost intact because it drifted through the sea, but scientists have now disconnected 19 km (12 miles). Scientists told AFP on Friday. More than twice the size of London, the giant iceberg, which weighs nearly 1 trillion tons, has been almost the same since it began to move north slowly in 2020. It drifts toward…

Wind break brings hope to Los Angeles fires
Families hug each other and cry as they look at their burnt-out homes in the Altadena neighborhood of Los Angeles County, California. Winds are expected to ease around Los Angeles on Friday, as massive efforts to extinguish five major fires wreaking havoc around the United States’ second-largest city intensify. One of the worst disasters to ever hit California, inferno has…

Chemists say it’s time to break 100-year-old rules and rewrite textbooks
Credit: Pixabay/CC0 Public Domain Chemists at UCLA have discovered a big problem with the basic rules of organic chemistry that have existed for 100 years. That’s not true at all. And they say, “It’s time to rewrite the textbooks.” Organic molecules are primarily composed of carbon and are characterized by having a specific shape and arrangement of atoms. Molecules known…
