Researchers have shown that there is an anti-correlation between the number of aggregation prone regions (APRs) in a protein's sequence and its solubility, suggesting that mutational suppression of APRs could provide a simple strategy to increase protein solubility.
Some bacteria that live inside paramecia, which are tiny aquatic organisms, use a coiled protein ribbon that unfurls like a Chinese paper yo-yo to deliver a toxin to threatening organisms. The protein packs a punch, bursting through membranes of the paramecia's competitors as it elongates.
A researcher is making major progress on a first-of-its kind device to free kidney patients from dialysis. He is building an implantable artificial kidney with microchip filters and living kidney cells that will be powered by a patient's own heart.
Engineers have modified the cotton candy machine to create complex microfluidic networks that mimic the capillary system in living tissue and have demonstrated that these networks can keep cells alive and functioning in an artificial three-dimensional matrix.
