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.
Hormones are blamed for everything from weight gain to mood swings and this December, Horizon takes a closer look at these chemical regulators and their effects on our bodies and minds. We explore the impact of the so-called love hormone on the human-dog relationship and what it can tell us about social disorders. We find out what’s being done to neutralise the hormone-disrupting chemicals that are found in water and sewage, and we discover the importance of hormonal rhythms in tracking disorders that can lead to obesity, heart disease and osteoporosis.
Forests cover around 30 % of the Earth’s surface, are home to millions of species, capture and store carbon dioxide (CO2), influence the local climate and provide us with water. This month, Horizon examines how the health of the world’s forests impacts on climate change. We explore the link between deforestation, forest degradation and CO2 emissions, examine the push to combine farming and forestry for better land management, and find out how scientists are using tree rings and DNA to combat illegal logging.
Hormonal disorders can affect people's immune systems, metabolism and even bones, and unravelling the mystery around something called ultradian rhythms could help improve diagnosis and lead to better treatments, according to Professor Eystein Sverre Husebye, who works at the Department of Clinical Science at the University of Bergen (UiB) in Norway.
Monitoring ultradian rhythms could speed up diagnosis.
Experts looked at how to increase the food from our oceans.
Bulgarian entrepreneur Kristina Tsvetanova says innovation is on the rise in Eastern Europe but more could be done.
