Researchers recently demonstrated the design of softwood lignin-based polymers with potential application as alternatives to petroleum-based polystyrene. These softwood materials can be obtained from sources such as pine, cedar, spruce, and cypress trees.
Scientists have for the first time shown that it is possible to derive from a human embryo so-called ?na´ve? pluripotent stem cells ? one of the most flexible types of stem cell, which can develop into all human tissue other than the placenta.
Researchers have created a hydrogel scaffold replicating the environment found within the human breast. The scaffold supports the growth of human mammary tissue from patient-derived cells and can be used to study normal breast development as well as breast cancer initiation and progression.
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.
