If humans are to travel to distant destinations in space like the moon or Mars, they’ll need ways to live for long periods of time. And one of the key challenges of that includes how to have safe food and water to eat and drink when far from Earth.
Robots that use artificial intelligence to recognise the health of fruit and vegetable crops and when they’re ready to harvest are being trialled to help small, organic and greenhouse farmers with weeding and patrolling for pests.
By harnessing the power of strong winds at higher altitude than turbines reach, airborne wind energy could be another key source of renewable energy, but it will need a combination of successful designs, more robust software and good storytelling to really take off.
New prosthetic technologies that stimulate the nerves could pave the way for prostheses that feel like a natural part of the body and reduce the phantom limb pain commonly endured by amputees.
We need to improve how we keep track of objects in space and predict where they will go in order to avoid collisions in Earth’s increasingly crowded orbit, according to Dimitra Stefoudi, a space law researcher from Leiden University in the Netherlands.
Applying a coat of paint on the walls of a house may soon help to heat it, saving energy and reducing CO2 emissions. It could also clean the air that we breathe, breaking down chemicals and pollutants, and eliminating harmful pathogens.
When Timothée Boitouzet studied architecture in Japan, where buildings need to survive earthquakes, he realised the next smart material might be one that humans have used for thousands of years – wood.
The red planet may be our best bet for finding out whether we’re alone in the universe.
Reducing crew numbers onboard ships could overcome labour shortages and increase shipping levels.
Metagenomics can help us spot emerging diseases such as coronavirus, says virologist Marion Koopmans.
