The world’s oceans are overfished, polluted and – for something that makes up 70% of the Earth’s surface – still little understood. This month, Horizon looks at some of the science that could help us take better care of our oceans, from robots trash collectors out at sea to finding ways to track the plastic that enters our waters. Plus, we look at how climate change is affecting plans for sustainable aquaculture, tech that can help divers reduce the cost of their dives by more than 50%, and the challenges facing research in the Black Sea.
A Roomba-like ocean trash collector modelled on a whale shark and a microplastic filter made from jellyfish slime could prevent litter from entering our oceans and help tackle a growing problem that poses threats to wildlife, deters tourists and impacts on coastal economies.
The structure of the EU’s next research funding programme is based on the mantra of ‘evolution, not revolution’ and so will not contain any major surprises, according to Jean-Eric Paquet, the EU’s recently appointed director-general for research and innovation, who takes up his new role on 3 April.
The act of confronting a troublesome past can be challenging by itself, and the Germans even have a word for it — Vergangenheitsbewältigung. Roughly one-third of current EU Member States spent decades behind the Iron Curtain, and many experienced one-party government for decades, but researchers see confronting uncomfortable history as part of a new common European identity — a shared experience that can bring people closer together.
A lot of lip service is being paid to making scientific papers free to access but when it comes to action there is a lot of hypocrisy, according to Robert-Jan Smits, the EU's outgoing director-general for research, science and innovation. He has recently been appointed the EU's special envoy on open access, tasked with helping make all publicly funded research in Europe freely available by 2020.
Swarms of firefighting drones could one day be deployed to tackle hugely destructive megafires that are becoming increasingly frequent in the Mediterranean region because of climate change, arson and poor landscape management.
