Rewriting the evolutionary history of critical components of the nervous system      (via sciencedaily.com)     Original source 

A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.

Study reveals oleoyl-ACP-hydrolase underpins lethal respiratory viral disease      (via sciencedaily.com)     Original source 

Respiratory infections can be severe, even deadly, in some individuals, but not in others. Scientists have gained new understanding of why this is the case by uncovering an early molecular driver that underpins fatal disease. Oleoyl-ACP-hydrolase (OLAH) is an enzyme involved in fatty acid metabolism. A study shows that OLAH drives severe disease outcomes.

Researchers ID body's 'quality control' regulator for protein folding      (via sciencedaily.com)     Original source 

Anyone who's tried to neatly gather a fitted sheet can tell you: folding is hard. Get it wrong with your laundry and the result can be a crumpled, wrinkled mess of fabric, but when folding fails among the approximately 7,000 proteins with an origami-like complexity that regulate essential cellular functions, the result can lead to one of a multitude of serious diseases ranging from emphysema and cystic fibrosis to Alzheimer's disease. Fortunately, our bodies have a quality-control system that identifies misfolded proteins and marks them either for additional folding work or destruction, but how, exactly, this quality-control process functions is not entirely known. Researchers have now made a major leap forward in our understanding of how this quality-control system works by discovering the 'hot spot' where all the action takes place.

Pre-surgical antibody treatment might prevent heart transplant rejection      (via sciencedaily.com)     Original source 

Anti-rejection regimens currently in use are broad immunosuppressive agents that make patients susceptible to infections. By using specific antibodies, it may be possible to just block the inflammation that leads to rejection but leave anti-microbial immunity intact.

Why carbon nanotubes fluoresce when they bind to certain molecules      (via sciencedaily.com)     Original source 

Nanotubes can serve as biosensors. They change their fluorescence when they bind to certain molecules. Until now, it was unclear why. Researchers have gained new insights into the cause of the fluorescence.

Bacteria in lakes fight climate change      (via sciencedaily.com)     Original source 

Methane-oxidizing bacteria could play a greater role than previously thought in preventing the release of climate-damaging methane from lakes, researchers from Bremen report. They also show who is behind the process and how it works.

How mortal filaments' self-assemble and maintain order: Align or die      (via sciencedaily.com)     Original source 

A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto 'dying to align': Misaligned filaments 'die' spontaneously to form a ring structure at the center of the dividing cell. The work could find applications in developing synthetic self-healing materials.

Breakthrough heart MRI technique accurately predicts heart failure risk in general population      (via sciencedaily.com)     Original source 

MRI scans could replace invasive heart tests, as new research shows they can reliably estimate pressures inside the heart to predict if a patient will develop heart failure.

Treating radiation wounds with aspirin hydrogels      (via sciencedaily.com)     Original source 

Radiation is a powerful tool for treating cancer, but prolonged exposure can damage the skin. Radiation-induced skin injuries are painful and increase a person's chances of infection and long-term inflammation. Now, researchers report an aspirin-containing hydrogel that mimics the nutrient-rich fluid between cells and accelerates healing of skin damaged by radiation in animals. With further development, the new salve could provide effective and rapid wound healing for humans.

A new mechanism for shaping animal tissues      (via sciencedaily.com)     Original source 

A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams have now found a mechanism by which tissues can be 'programmed' to transition from a flat state to a three-dimensional shape.

Increasing solid-state electrolyte conductivity and stability using helical structure      (via sciencedaily.com)     Original source 

Solid-state electrolytes have been explored for decades for use in energy storage systems and in the pursuit of solid-state batteries. These materials are safer alternatives to the traditional liquid electrolyte -- a solution that allows ions to move within the cell -- used in batteries today. However, new concepts are needed to push the performance of current solid polymer electrolytes to be viable for next generation materials.
