Evolution of Life’s Molecular Systems: Insights into the Rise of Nanomachines

Researchers at Université de Montréal (UdeM) have made a significant discovery regarding the evolution of molecular systems crucial to the development of life. Through the linking of molecules, they have uncovered insights into the emergence of intricate self-regulating mechanisms. Alexis Vallée-Bélisle, a professor at UdeM and the lead researcher of the investigation, explained that life’s sustenance on our planet stems from myriad nanostructures. These nanomachines have undergone evolution over countless years.

Biofilm Microstructure Could Enhance Pathogenic Infection Control: Microbial Ecology

Generally, bacteria are envisioned as tiny, single-cell organisms scattered thinly on surfaces or floating in liquids. However, in various settings, bacteria prefer to grow in clusters known as biofilms. The formation of biofilms provides certain advantages to bacteria. In these clusters, bacteria can collaborate and create a protective environment that enhances their survival and growth. Biofilms, while aiding in kombucha tea production, present a challenge by complicating the control of bacterial growth. When bacteria form a biofilm, it acts like a protective shield, making the cells resistant to antibiotics.

Molecular Atlas of Spider Silk: Fibrous Protein Assembly

Researchers at Southwest University in China have successfully constructed the chromosomal-scale genome assembly as well as the complete spidroin gene set of the golden orb-weaving spider. The chromosomal-scale genome assembly represents genome sequence; while the spidroin refers to proteins in spider silk. Different spidroins determine the varieties in spider silks.   With this new insight, researchers can dive deeper into the silk-producing capabilities of spiders. Eventually, this might lead to the development of new materials with desirable mechanical properties.

DNA Mutations are Not Random: Genetics Challenges Evolutionary Theory

Plant evolves to protect itself, there is no random mutation at DNA level. In a collaborative effort, researchers from University of California, Davis, and the Max Planck Institute for Developmental Biology in Germany concluded that when it comes to mutations, there is no such thing as randomness. In fact, it is in a non-random way that benefits the plant, claimed Grey Monroe, an assistant professor in the UC Davis Department of Plant Sciences.

Probiotics Protect Bleached Corals from Death: Beneficial Microorganisms

Coral reefs harbour the highest biodiversity of any ecosystem globally. Constant rise in temperature is causing havoc to marine life as well. Coral reefs across the globe are suffering from bleaching and mass mortality due to warming ocean temperatures. Recent research by King Abdullah University of Science and Technology (KAUST) shows probiotic treatment can boost coral health.
