We've devised a way to factor in noise annoyance levels in drone design.
South Africa produces about 16% of sub-Saharan Africa’s maize.
As African economies recover from the COVID-19 pandemic, governments should explore technologies like global positioning systems and blockchain for use in the registration of land rights.

New research suggests individual bees are born with one of two learning styles – either curious or focused. Their genetic tendency has implications for how the hive works together.
They began as wartime technology, but now drones are changing the way we witness the world, especially when we can't see it for ourselves.
The federal government has used military-grade border patrol drones like this one to monitor protests in US cities.

The COVID-19 crisis highlights the importance of supply chains. But even with the increased recent attention, most supply chains remain murky. Consumers can play a key role in lifting that cloud.
Reverse-engineering birdflight helped researchers create a powerful new kind of drone.
Inspired by the aerobatic manoeuvres of the swift, a new "flapping wing" aircraft can hover, glide and dive much better than quadcopter-style drones.
Recent shark-related deaths fuel the debate around the best way to keep people safe in the water, without hurting marine wildlife.

An influx of drone technology will mean changes to how cities are built.
Koalas are notoriously difficult to detect. Traditional methods are costly and labour intensive. So we found a more efficient way to locate koalas in eastern NSW, using drones.
The only way to learn about the sensory abilities of dolphins is with the help of trained dolphins.
Wild dolphins are fast, smart and hard to study, but it is important to understand how human actions affect their health. So we are building a drone to sample hormones from the blowholes of dolphins.
A swarm of roughly 40 million desert locusts can eat the same amount of food in one day as about 35,000 people.
A robot dog called Spot patrols a Singapore park playing a recorded message telling people to observe physical distancing measures.
Smart city solutions have proved handy for curbing the contagion, but recent experience has also shown how much they rely on public trust. And that in turn depends on transparency and robust safeguards

Police are using drones to enforce rules and surveil and intimidate people.
Some species, including blue whales, spend little time at the surface. So despite their overwhelming size, they can be hard to find and tough to study.
The usefulness of drones to the medical sector has been clear for several years – and well-funded start-ups have been trialling services around the world.
Police in Bhopal, India use a drone to monitor adherence to lockdown measures.
Start-ups in India, many in Kerala, have taken up the challenge of finding innovative solutions to the problems raised by COVID-19.

Robots are helping health care workers and public safety officials more safely and quickly treat coronavirus patients and contain the pandemic. They have something in common: They're tried and tested.
While 'good drones' have been valuable in this pandemic, using drones to embed new systems of surveillance could be a dangerous and slippery slope.
