A new breakthrough in understanding regeneration in a marine worm      (via sciencedaily.com)     Original source 

The sea worm Platynereis dumerilii is only a few centimeters long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation. By focusing more specifically on the mechanisms at play in the regeneration of this worm's tail, a research team has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis.

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.

Genetic patterns of world's farmed, domesticated foxes revealed via historical deep-dive      (via sciencedaily.com)     Original source 

Domesticated animals play a prominent role in our society, with two-thirds of American families enjoying the companionship of pets and many others relying on animal products for their nutritional needs. But the process of domestication remains a bit of a mystery.

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.

Researchers develop fastest possible flow algorithm      (via sciencedaily.com)     Original source 

Computer scientists have written a network flow algorithm that computes almost as fast as is mathematically possible. This algorithm computes the maximum traffic flow with minimum transport costs for any type of network. It thus solves a key question in theoretical computer science. The superfast algorithm also lays the foundation for efficiently computing very large and dynamically changing networks in the future.

New deep-learning model outperforms Google AI system in predicting peptide structures      (via sciencedaily.com)     Original source 

Researchers have developed a deep-learning model, called PepFlow, that can predict all possible shapes of peptides -- chains of amino acids that are shorter than proteins, but perform similar biological functions. Peptides are known to be highly flexible, taking on a wide range of folding patterns, and are thus involved in many biological processes of interest to researchers in the development of therapeutics.

Researchers find genetic stability in a long-term Panamanian hybrid zone of manakin birds      (via sciencedaily.com)     Original source 

We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, and studying them can reveal key insights into how species boundaries evolve -- or sometimes blur. Researchers now describe a hybrid zone between two manakin species in Panama that has overall remained relatively stable over the past 30 years.
