Challenging the dogma of gene evolution, and how chiral nanoparticles could give vaccines a boost.
In this episode:
00:45 Genome mutations may be less random than previously thought
A long-standing doctrine in evolution is that mutations can arise anywhere in a genome with equal probability. However, new research is challenging this idea of randomness, showing that mutations in the genome of the plant Arabidosis thaliana appear to happen less frequently in important regions of the genome.

16:11 How a left-handed nanoparticle could give vaccines a boost
The chirality of a molecule – whether it has a left- or right-handed orientation – can have significant impacts on how it works. This week, a team show that left-handed gold nanoparticles can stimulate the immune system of mice, and boost the activity of a flu vaccine.

A “magical” coral reef stretching as far as the eye can see has been discovered off the coast of the South Pacific island Tahiti. The beautiful reef took around 25 years to grow and was found in the “twilight zone”, where it is highly unusual to unearth such a find as there is barely enough light to sustain life. “It was magical to witness giant, beautiful rose corals which stretch for as far as the eye can see. It was like a work of art,” said French photographer Alexis Rosenfeld, who led the team of international divers that made the discovery. The acres of giant corals in pristine condition show no sign of being damaged by climate change and demonstrate just how little we know about the ocean, according to experts. They say it shows the need to protect the world’s remaining healthy reefs from environmental damage. Read the full story here: https://www.telegraph.co.uk/world-new..
