New cancer drug sabotages tumour's escape route →
Some untreatable cancers could soon be held in check by an experimental drug that targets not only the tumour itself, but also how it evolves to spread through the body.
The new drug, Cabozantinib, or cabo for short, simultaneously neutralises two mechanisms cancers need to survive. First, it chokes each tumour’s blood supply by blocking a molecule on the surface of its blood vessels,...

'Immortal' Tasmanian devil brings vaccine hope →
A bizarre facial cancer threatening to wipe out the Tasmanian devil probably evolved from a single female about 16 years ago, new scans of the cancer reveal. The scans are also helping to identify gene mutations found in the cancer but not healthy tissue, which might provide targets for a vaccine to rescue the endangered species.
Devil facial tumour disease is unusual in that the cancer cells...

'DNA robot' targets cancer cells →
Scientists have developed and tested a “DNA robot” that delivers payloads such as drug molecules to specific cells.
The container was made using a method called “DNA origami”, in which long DNA chains are folded in a prescribed way.
Then, so-called aptamers - which can recognise specific cell types - were used to lock the barrel-shaped robot.

Morphogenesis & Pattern Formation Mathematical biology and Morphogenesis was the last work in which Turing worked on. He wanted to decode the markings and patterns formed in nature such as patterns on animals or patterns formed in plant structures and how they emerge. His reaction-diffusion model was the basis to understanding pattern...

Clint Eastwood helps reveal secrets of brain... →
Clint Eastwood might sound like an unlikely candidate to help investigate the evolution of the brain, but he has lent a helping hand to researchers doing just that. It turns out that brain regions that do the same job in monkeys and humans aren’t always found in the same part of the skull.
Previous studies comparing brains across species tended to assume that human brains were just...

SPACE DOCTOR! →
Welcome to the Extraterrestrial Gene Therapy Lab!
As Space Doctor, you’ll use your gene therapy knowledge to treat three ailing aliens who come into your clinic.
Before starting, you might want to review Tools of the Trade and the Gene Therapy Case Studies found in other sections of this module.
Space doctor hell yeah!
