Scientists have come up with a way of developing new drugs by using so-called “genetic scissors”. These are molecules which literally snip out 40 disease genes in order to test new drugs on them. They say that the technique know as crisper will enable them to test new drugs more quickly, cheaply and accurately.
We have had a very precise technology to do exactly what we want to do.
It’s hoped the technology will speed the development of medicines for a range of illnesses including diabetes, heart disease and many cancers. Another doctor from the European Bioinformatics Institute explains how crisper works.
In particular in cancer, what you can do is you can take a cancer cell which you know now has gone wrong. It’s growing inappropriately. And then you can test in a single experiment, you can test every single gene. And so a single experiment will do that for all of them.
Previously each one of those will be a projectby itself. And you can not just do that on one cancer line, you’ll do it on maybe five hundred or thousand. And this way you can start to say “Aha, this particular gene is the gene that we should try and build a drug to”. About ninety percent of drugs fail. And there are many points where their failure happens. And this technology allows people to do experiments that are just transformative cuz you can test all the genes at once.
And you can find out more about that on the health pages of our website.
In 1977, a 27-year old woman Robyn Davidson decided to embark on an epic solo adventure. Her plan was to trek nearly three thousand kilometers across the Australian outback with only four camels and her dog for company. Rick Smolan photographed her trip for the National Geographic magazine. And his pictures are simply stunning. They’ve been republished in his new book Inside Tracks. Rick Smolan spoke to Dan Damon about this extraordinary adventure and how it began.
Robyn Davidson when she was 27 years old decided for reasons that she still never shared with anybody. Sheset off on this sort of strange journey alone, 1,700 miles across the Australian outback out to the IndianOcean. So she had four camels and her dog. And no one knew why she was doing it. And I was sent by National Geographic to find her five times during this nine-month journey and to photograph her.
It was one of the most uncomfortable journeys anybody could plan for. Here is an image of her covered in flies.
