A stiff defense: Rethinking gum disease
Dentists Kyle H. Vining and Hardik Makkar from the University of Pennsylvania are taking a new approach to treating severe gum disease by focusing on the physical properties of gum tissue. Using a Jell-O-like hydrogel, their team discovered that physically stiffening model tissues dramatically reduced inflammation, paving the way to strengthen the gums and halt the destructive cycle of periodontal disease.

Howard G. Smith MD, AM on Instagram: "Injectable Gel Restores Voices
Scientists at Canada’s McGill University have developed a novel injectable gel that could one day help people recover their voices after vocal cord injury and avoid repeated restorative procedures.
Our voices are normal when vocal cords meet and produce vibrations that are modified by ours lips and tongues. Voice loss often becomes persistent when injured vocal cords fail to meet and produce the necessary vibrations.
Current injectable treatments move the cords together but break down quickly necessitating multiple injections. Each additional injection can increase the risk of further damage to the delicate vocal cords.
In a preclinical study published in the journal Biomaterials, McGill researchers show that their newly developed hydrogel, made from natural tissue proteins, stays intact for weeks. This is far longer than existing materials and gives injured vocal cords sufficient time to heal properly.
The gel has not yet been tested in humans. Once clinical trials are complete, the gel could lead to longer-lasting, minimally invasive therapy for vocal inadequacy…..someday soon,

What if a

#inject an electricity-conducting liquid into the body, let it temporarily solidify to record
#nerve signals or jump-start healing, and then return it to liquid form for easy removal?

#Wassersammler entzieht #trockener #Wüstenluft #Wasser:
Die #Atacama-Wüste gilt als die trockenste Region der Welt.
Ein solcher #Wassersammler entzieht nachts der kühlen #Luft #Feuchtigkeit. Wenn die Sonne ihn tagsüber erwärmt, gibt er das Wasser ab. Das Team um Bachir El Fil vom Georgia Institute of Technology nutzt ein #Hydrogel als #Absorbermaterial. Es basiert auf vernetzten #Polyacrylamid-Polymeren, die mit dem #Salz #Lithiumchlorid versetzt wurden.

New technique expands plant cells for better microscopic imaging
The way we study plant cells is expanding—literally—thanks to new research from Kevin Cox, an assistant professor of biology in Arts & Sciences at Washington University in St. Louis and an assistant member of the Donald Danforth Plant Science Center. In a new study published in The Plant Journal, Cox and his team describe how they have developed ExPOSE (Expansion Microscopy in Plant Protoplast Systems), a technique that brings expansion microscopy to plants.
