2 December 17: Deep blue secrets

I once wrote an article about how marine life is helping us to cure disease. They may look like they’re simply anchored to a rock or snaffling around on the seabed, but species such as the cone snails and deep sea sponges are helping modern medicine to fight the likes of cancer and chronic pain. Then there’s the stunning purple-blue sea whip plant, Pseudopterogorgia elisabethae, whose extracts from its delicate fronds have been shown to speed up wound healing. Amazing. Makes me love the briny blue even more.
