Since being released on the world in 2012, the biotechnological tool CRISPR has been making headlines. Biologists used to rely on the relatively blunt tools of genetic modification, but this new tool is so precise and versatile that they now speak of gene editing instead. For people in a hurry, Nessa Carey here provides a primer on the powers and pitfalls of gene editing. Hacking the Code of Life is accessible to readers without much background in genetics, focusing more on the applications and the questions it raises than the nitty-gritty details of the tool itself.
When I reviewed the book Defending Biodiversity: Environmental Science and Ethics, one of the reasons that was discussed as to why we should protect nature was the possibility of undiscovered pharmaceutical drugs. Seasoned ethnobotanist Robert A. Voeks shows that this so-called jungle medicine narrative has a long history. Though partially true, it equally contains parts myth, sentimentality, and nostalgia. However, if you are expecting a sceptical critique of superstitious indigenous practices – I was initially wondering whether the book would – no, this book delivers something far more interesting. Without belittling traditional knowledge, Voeks instead exposes the flaws in our interpretation and delivers a nuanced and fascinating ethnobotanical history lesson to boot.
Antibiotics have been saving human lives since the drug Salvarsan was discovered in 1932. Penicillin went into mass-production in 1942. This is not a long time when you think about it, but a world without the protection offered by them already seems unimaginable. Not only have they offered protection from diseases such as tuberculosis, and stopped infections following injury or childbirth, they have also allowed us to develop surgical techniques requiring immune system suppression such as organ transplants. However, careless use of antibiotics has accelerated evolution of drug-resistant bacteria such that we are about to lose their protection.
