Remember those colorful 'grow capsules' that blossom into animal-shaped sponges in water? Using a similar idea, scientists have developed biodegradable polymer grafts that, when surgically placed in damaged vertebrae, should grow to be just the right size and shape to fix the spinal column.
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.
