Novel Antidote to Liver Cancer
A US-based research team has designed a protocell that can ferry a drug cocktail to kill tenacious drug-resistant liver cancer cells. The protocell has been tagged with peptide to specifically target liver cancer cells.
The protocell showed 10,000-fold greater affinity for cancer cells than normal liver cells and immune cells. The researchers say that protocells can be loaded with combinations of therapeutic (drugs, small interfering RNA and toxins) and diagnostic (quantum dots) agents.
The protocell is actually porous nanoparticle-supported lipid bilayers exhibiting combined properties of liposomes and nanoporous particles. This new avenue to treat liver cancer will shun the need of conventional chemotherapy that usually unleashes side effects. The study has been published in the 17 April 2011 online issue of Nature Materials.

| First Computer Mouse (Photo credit: www.geekologie.com) |
It helps you while typing words on a word processor. It aids in drawing and painting a nice digital picture. With a simple click, it connects you to Internet. Yes, I am talking about computer mouse that almost permeates every sphere of our gadget-savvy life. But, have you ever wondered how the first computer mouse looked like? Who invented it?
The earliest computer mouse was very different from what we see now. The first mouse was actually a wooden shell with two metal wheels. A wire tail came out of this system. At that time, this device was named as ‘X-Y position indicator for a display system’.
Douglas Engelbart, a researcher at the Stanford Research Institute invented this earliest precursor to modern day mouse. Without realizing its value, the institute licensed the device to Apple for “something like $40,000”.
