New vestiges of the first life on Earth discovered in Saudi Arabia

Stromatolites are the earliest geological record of life on Earth. These curious biotic structures are made of algae carpets growing toward the light and precipitating carbonates. After their first appearance 3.48 Ga ago, stromatolites dominated the planet as the sole living carbonate factory for almost three billion years. Stromatolites are the earliest geological record of life…

New photonic crystal approach can enable sensitive and affordable detection of biomarkers

Biomarkers are small molecules of interest to researchers, because they can indicate underlying diseases, often even before symptoms even appear. However, detecting these markers can be challenging as they are often present in very low quantities, especially in the early stages of a disease. Traditional detection methods, while effective, usually require expensive components like prisms,…

Scientists are testing mRNA vaccines to protect cows and people against bird flu

The bird flu outbreak in U.S. dairy cows is prompting development of new, next-generation mRNA vaccines—akin to COVID-19 shots—that are being tested in both animals and people. The bird flu outbreak in U.S. dairy cows is prompting development of new, next-generation mRNA vaccines—akin to COVID-19 shots—that are being tested in both animals and people. Agriculture Phys.org – latest…

Mussels downstream of wastewater treatment plant contain radium, study reports

Burrowed into streambeds and rarely moving for their decades-long lifespans, freshwater mussels are biomonitors, meaning they indicate how clean their environment is, according to Penn State researchers. As the bivalves feed on organic matter and filter the water around them, their inner tissues and hard shells begin to reflect whatever is in their environment—including radioactive…
