The Story of Crispr-Cas9 and Why Gene Editing Will Change Everything.
The discovery of an extremely precise, cheap and easy-to-use genome editing tool is causing a revolution in the field of genetic modification. It has the potential to cure thousands of diseases, to massively boost food security and will almost certainly herald the dawn of the era of genetically enhanced humans, changing the human genome forever. It’s a very big deal that has scientists equally excited and concerned.
In the 1997 science fiction film Gattaca, normal human beings are deemed as inferior to an upper class of genetically engineered “valid” humans, all with 20/20 vision, perfect skin and teeth, superior athleticism and intelligence and no genetic predisposition to genetic disease.
Fast-forward about 20 years: Chinese scientists have just announced (in November) that they were the first to use a revolutionary gene-editing technique called CRISPR-Cas9 to inject gene-altered cells into a living person, a patient with aggressive lung cancer. This, according to Nature, is part of a groundbreaking clinical trial at the West China Hospital in Chengdu that will likely kick off“Sputnik 2.0”, a biomedical space race between China and the US to see who can get gene-edited cells into the clinic first. Gene editing, and soon genetic enhancement in humans, has suddenly become a reality.

Making the most out of your grinder
THE HUMBLE BENCH GRINDER IS A STAPLE of the handyworker's home shop, largely due to its versatility. But, while you can employ one to remove metal from just about anything, the traditional kind may not provide the precision you need for every grinding operation. Here, we shed light on the best ways to use the different types of grinders, gleaned from our testing.

F1 taught me that speed starts with comfort
AS A FAN OF MOTORSPORT, I'M ALWAYS fascinated with the finer details that go into Formula One racing. Piloting the fastest racing cars on the planet subjects drivers to savage forces - up to 6 G's under braking which has led to an almost endless pursuit of comfort.
