3-D technology enriches human nerve cells for transplant to brain

Scientists have developed a 3D micro-scaffold technology that promotes reprogramming of stem cells into neurons, and supports growth of neuronal connections capable of transmitting electrical signals. The injection of these networks of functioning human neural cells - compared to injecting individual cells - dramatically improved their survival following transplantation into mouse brains.

Spongy material helps repair the spine (w/video)

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.

Research team documents design of wood-based polymers

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.

Making better enzymes and protein drugs

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.
