Washington, Nov 7 : For the first time ever, MIT engineers have attached tiny "backpacks" in cells, allowing them to deliver chemotherapy agents, diagnose tumours or become building blocks for tissue engineering.

According to Michael Rubner, director of MIT''s Center for Materials Science and Engineering and senior author of a paper on the work, this is the first time anyone has attached such a synthetic patch to a cell.

The polymer patch system consists of three layers, each with a different function, stacked onto a surface. The bottom layer tethers the polymer to the surface, the middle layer contains the payload, and the top layer serves as a "hook" that catches and binds cells.

Washington, Nov 7 : Growth hormone therapy can significantly increase height in children with short stature, says a new study.

The study involving 150 short children, followed over a period of 20 years showed that growth hormone was effective in increasing the final height of in GH deficient children with short stature, as well as non GH deficient kids. However, further studies are still required.

The kids were randomized to no treatment, low GH dosage, or high GH dosage. The treatment could increase their height to nearly eight inches.

Melbourne, Nov 7 : Canadian born actress Pamela Anderson’s Ugg boots are now on demand from men who want to add them to their fashion accessories.
