This month, Horizon looks at the growing field of bio-inspired robotics to find out how nature is inspiring machine design. We investigate the surgical tools that mimic how octopus arms become flexible or stiff on demand, sensors based on the orientation ability of maggots, and marine robots inspired by lilypads, fish and mussels.
Animals have evolved sophisticated ways of processing sensory data to make sense of their surroundings. Now, robotics researchers are drawing inspiration from biological processes to improve the way machines handle information, perceive their surroundings, and react to stimuli.
Robotic arms inspired by the octopus could help doctors to perform new operations using keyhole surgery. By mimicking the octopus arm to transform from soft and flexible to stiff and rigid, these soft robotic tools could increase the scope for operations through small incisions.
The model of our universe as expanding at an accelerated rate has given rise to theoretical constructs such as dark energy and dark matter, which scientists believe could make up 95% of the universe. In September, Horizon takes a deeper look at what we really know about the expanding universe. We speak to Prof. Subir Sarkar, who believes that the Nobel-winning discovery that universe expansion acceleration could be a fluke, and the scientists who are trying to answer the question by allowing us to better measure the expansion rate. We also look at the significance of accurately measuring gravity in deep space, and what dark matter haloes can tell us about the existence of dark energy.
This month, Horizon takes an in-depth look at a shared human trait – our emotions. We find out how science is seeking to better understand and regulate human emotions across a range of applications, from mental health to politics. We uncover the implications of a neuroscientist’s efforts to determine how the brain controls fear and anxiety, with possible implications for treating mental health disorders and autism. We explore how emotions shape our politics and ask whether this can help provide a different perspective on the Israeli-Palestinian conflict. And we look at research examining how apps and online games can help people manage their emotional sides.
Earthworms and tiny water fleas could help deliver clean water to billions of people living in remote areas of the world by eating up sewage and other pollution.
A sister and brother who created shock-activated protective gear featuring a starch liquid for people who in-line skate, motorcycle and do other risky sports, won one of the three first prizes at this year’s European Union Contest for Young Scientists (EUCYS).
Biofilters offer in-situ low-maintenance ways of treating wastewater.
Winners from Germany and Canada take home top prizes.
Electric cars with liquid batteries could be charged in minutes, says Prof. Cronin.
