Proteins trapped in glass could yield new medicinal advances


The protein, captured in an extremely thin piece of glass — around 50 nanometres in diameter, is sliced up, atom by atom, with the help of an electrical field. It is then analysed through Atom Probe Tomography, and the 3D structure is recreated on a computer.

Researchers at Chalmers University of Technology, Sweden, have developed a unique method for studying proteins which could open new doors for medicinal research. Through capturing proteins in a nano-capsule made of glass, the researchers have been able to create a unique model of proteins in natural environments. The results are published in the scientific journal, Small.

Researchers develop new method to grow human skin from stem cells that replicates the real thing

The method could viably produce enough skin samples to be used commercially for drug and cosmetics testing.

The use of animal testing for medical research than for cosmetics testing is much easier to defend.  Yet many cosmetics companies continue to test on animals to ensure that their products don’t produce negative outcomes for their human customers.
