Research shows how RNA 'junk' controls our genes      (via sciencedaily.com)     Original source 

Researchers have made a significant advance in understanding how genes are controlled in living organisms. The new study focuses on critical snippets of RNA in the tiny, transparent roundworm Caenorhabditis elegans (C. elegans). The study provides a detailed map of the 3'UTR regions of RNA in C. elegans. 3'UTRs (untranslated regions) are segments of RNA involved in gene regulation.

Proteins and fats can drive insulin production for some, paving way for tailored nutrition      (via sciencedaily.com)     Original source 

When it comes to managing blood sugar levels, most people think about counting carbs. But new research shows that, for some, it may be just as important to consider the proteins and fats in their diet. The study is the first large-scale comparison of how different people produce insulin in response to each of the three macronutrients: carbohydrates (glucose), proteins (amino acids) and fats (fatty acids). The findings reveal that production of the blood sugar-regulating hormone is much more dynamic and individualized than previously thought, while showing for the first time a subset of the population who are hyper-responsive to fatty foods.

Shrinking glaciers: Microscopic fungi enhance soil carbon storage in new landscapes created by shrinking Arctic glaciers      (via sciencedaily.com)     Original source 

Shrinking glaciers expose new land in the Arctic, creating unique ecosystems. Researchers studied how microbes colonize these barren landscapes. The study reveals a crucial role for specific fungal species in capturing and storing carbon in the newly formed soil. These findings suggest fungi are essential for future carbon storage in the Arctic as glaciers continue to recede.

Degradation of cell wall key in the spread of antibiotic resistance      (via sciencedaily.com)     Original source 

A study provides new clues in the understanding of how antibiotic resistance spreads. The study shows how an enzyme breaks down the bacteria's protective outer layer, the cell wall, and thus facilitates the transfer of genes for resistance to antibiotics.

Researchers thwart resistant bacteria's strategy      (via sciencedaily.com)     Original source 

Bacteria are experts at evolving resistance to antibiotics. One resistance strategy is to cover their cell walls in sticky and gooey biofilm that antibiotics cannot penetrate. A new discovery could put a stop to this strategy.

Unraveling the origin and global spread of the potato blight pathogen      (via sciencedaily.com)     Original source 

A new study challenges the common theory that the devastating potato blight pathogen Phytophthora infestans originated in Mexico. Researchers meticulously reconstructed its global migration history and found it likely originated in the South American Andes before spreading globally. This research provides significant insights into the pathogen's evolutionary journey, which is crucial for developing better disease management strategies worldwide.

Melanin from cuttlefish ink as a sustainable biomass resource      (via sciencedaily.com)     Original source 

Melanin is a ubiquitous compound in nature, produced by many organisms. However, its potential as a biomass resource to produce value-added chemicals and materials remains relatively unexplored. In a recent study, researchers investigated the chemical decomposition of melanin derived from cuttlefish ink and showcased its application in the synthesis of biopolymer films and particles. Their efforts will hopefully pave the way to the adoption of melanin upcycling.

Long-standing marine mystery solved: How algae get nitrogen to grow      (via sciencedaily.com)     Original source 

Scientists shed light on an unexpected partnership: A marine diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean. This symbiosis likely plays a key role for global marine nitrogen fixation and productivity, and thus uptake of carbon dioxide. The newly-discovered bacterial symbiont is closely related to the nitrogen-fixing Rhizobia which live in partnership with many crop plants and may also open up new avenues for engineering nitrogen-fixing plants.
