New research uncovers biological drivers of heart disease risk      (via sciencedaily.com)     Original source 

Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.

New approach to tackling bacterial infections identified      (via sciencedaily.com)     Original source 

Researchers have identified a new approach to controlling bacterial infections. The team found a way to turn on a vital bacterial defense mechanism to fight and manage bacterial infections. The defense system, called cyclic oligonucleotide-based antiphage signaling system (CBASS), is a natural mechanism used by certain bacteria to protect themselves from viral attacks. Bacteria self-destruct as a means to prevent the spread of virus to other bacterial cells in the population.

Researchers discover key to molecular mystery of how plants respond to changing conditions      (via sciencedaily.com)     Original source 

A team of researchers recently published a pioneering study that answers a central question in biology: how do organisms rally a wide range of cellular processes when they encounter a change -- either internally or in the external environment -- to thrive in good times or survive the bad times? The research, focused on plants, identifies the interactions between four compounds: pectin, receptor proteins FERONIA and LLG1 and the signal RALF peptide.

A new origin story for deadly Seattle fault      (via sciencedaily.com)     Original source 

The Seattle fault zone is a network of shallow faults slicing through the lowlands of Puget Sound, threatening to create damaging earthquakes for the more than four million people who live there. A new origin story, proposed in a new study, could explain the fault system's earliest history and help scientists improve hazard modeling for the densely populated region.

Extra fingers and hearts: Pinpointing changes to our genetic instructions that disrupt development      (via sciencedaily.com)     Original source 

Scientists can now predict which single-letter changes to the DNA within our genomes will alter genetic instructions and disrupt development, leading to changes such as the growth of extra digits and hearts. Such knowledge opens the door to predictions of which enhancer variants underlie disease in order to harness the full potential of our genomes for better human health.

Microbial division of labor produces higher biofuel yields      (via sciencedaily.com)     Original source 

Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels. Their approach relies on careful timing and a tight division of labor among synthetic yeast strains to yield more ethanol per unit of plant sugars than previous approaches have achieved.

A clutch stretch goes a long way      (via sciencedaily.com)     Original source 

New results reveal a new mode of force transmission in which dynamic molecular stretching bridges the extracellular matrix and flowing F-actin moving at different speeds. This discovery underscores the necessity of molecular elasticity and random coupling for sufficiently transmitting force. The findings also call for revising the role of molecular unfolding.

Gut bacteria can process dietary fiber into an anti-allergy weapon      (via sciencedaily.com)     Original source 

Short-chain fatty acids (SCFAs), which are produced by gut bacteria from dietary fiber, regulate our immune system, but the mechanism of their action remains unknown. In a recent study, researchers investigated how SCFAs interact with mast cells, a type of white blood cell that plays a central role in allergic reactions. Their findings and insights could lead to innovative and effective anti-allergy medications, supplements, and diets, paving the way for healthier lives.

Shining a new light on the tug-of-war between virus and host      (via sciencedaily.com)     Original source 

The interplay between ribonucleic acid (RNA) and proteins is not only important for maintaining cellular homeostasis but is also at the center of the tug-of-war between virus and host. Until now, there has been no method to globally map direct interactions of individual RNA regions in an unbiased fashion without the need for genetic modification of the target RNA or cell. Researchers have now developed a breakthrough tool that overcomes this limitation.
