New antibiotic candidates for drug-resistant bacteria may reside inside prions, misfolded proteins in the brain best known for rare and fatal degenerative brain diseases. Prion and prion-like proteins may hide short peptides, ...
Methane is one of the most powerful greenhouse gases, and lakes and wetlands are among its largest natural sources. In many lakes, methane can be seen bubbling up from the bottom and escaping directly into the atmosphere.
Researchers at the University of São Paulo (USP) in Brazil have discovered 45 new toxins produced by Salmonella bacteria, some of which are associated with foodborne infections. The study was conducted at the Center for Research ...
Researchers have characterized the oral microbiomes of the Japanese population across time by analyzing the DNA preserved in dental calculus of human skeletal remains. The researchers compared microbial composition in dental ...
Living in the Dead Sea would be a very unpleasant experience for most creatures. With salt concentration above 30% and temperatures ranging from 10–50°C, it takes unique environmental adaptations to survive in such harsh ...
How did life make the leap from single cells to coordinated, multicellular organisms? And how do genetically identical cells still perform a version of that feat every time an embryo begins to take shape?
Stored in an open-air warehouse in tropical Darwin, Australia, are dozens of trays containing cylindrical cores of rock. They are from drill holes bored hundreds of meters below the surface by mineral exploration companies ...
Advances in DNA sequencing have expanded our view of the microbial world, but the inability to cultivate most microbes has been a major constraint. Now, a systematic, predictive framework that combines existing genomic and ...
In a new paper, an international team led by scientists from Charles University, Czechia, has brought evidence linking widespread release of methane (CH₄)—a strong greenhouse gas—from the Greenland Ice Sheet (GrIS) to a warmer ...
A study conducted in the Brazilian state of Amazonas has demonstrated that small amounts of Amazonian dark earth (ADE)—an anthropogenic soil created by ancient Amazonian populations—can increase the height and diameter of ...
