Wildlife populations around the world are in crisis. Recent analysis by the World Wide Fund For Nature estimated that over the past 50 years, wildlife populations have reduced by 73 per cent. In the face of these unprecedented declines, it's more important than ever that scientists understand the challenges animals face and how they're responding to a changing planet. This requires data collection on a scale never attempted before - tracking the lives of animals at a global level and scientists are turning to technology to make this mammoth task possible.
The development of radio-tracking technology has already opened many new research avenues for scientists interested in animal behaviour, but these studies have been limited by the large size of the tracking devices and the need to follow the animals with receivers, or retrieve the tags later, to access the data.
In industry, new technological advances such as miniaturised sensors and communication devices have enabled the development of large-scale wireless digital networks that track the location and status of objects, from shipping containers to factory equipment - known as the 'Internet of Things' or IoT.
ICARUS the International Cooperation for Animal Research Using Space - aims to leverage this technology to create a global animal observation network to track and monitor wildlife on an unparalleled scale. The system uses state-of-the-art miniature transmitters to relay data about animals' movements, activity and even health, to receiver antennae in space, allowing scientists to tap into a wealth of research data through their computers.
"We're about to have an internet of animals and that's super exciting," says Prof Martin Wikelski, Director of the Department of Migration at the Max Planck Institute of Animal Behavior and ICARUS Initiative founder.

COULD MARINE CLOUD BRIGHTENING HELP US FIGHT CLIMATE CHANGE?
The theory behind marine cloud brightening is that brighter or whiter clouds reflect more sunlight back into space.
IS IT SAFE TO RUN EVERY DAY, OR SHOULD I DITCH MY RUN STREAK TO SAVE MY KNEES?
A running streak, where you run every day without taking rest days, can be highly motivating and beneficial for overall fitness. Running is great cardiovascular exercise and isn't to be discouraged (and finding a routine with some consistency is great). Getting a bit of exercise as often as possible is also hugely beneficial for your mental health.
WHAT MAKES THE MEDITERRANEAN DIET SO GOOD FOR US?
The Mediterranean diet may help you live longer, especially if you also adopt the lifestyle of people living near the Med during the 1950s.
WHAT IS MEXICO'S BLUE HOLE?
The world's deepest blue hole (marine sinkhole) lies off the coast of Mexico's Yucatán Peninsula. It's at least 420m (1,378ft) deep, but explorers still haven't found its bottom.
HOW CAN I TELL IF I'VE GOT HIGH CORTISOL LEVELS?
Cortisol is a hormone produced by glands in our bodies called the adrenal glands, which sit above the kidneys. It plays a critical role in various bodily functions, including regulating metabolism, reducing inflammation and helping the body respond to stress. While essential for our health, chronic elevation of cortisol levels can lead to several issues.
THE LUNGFISH
In 1836, European scientists discovered a peculiar animal from the River Amazon that they struggled to identify. Its eel-like body was a few feet long and its air-filled lungs persuaded anatomists it must be a reptile.
ARE WE THE ONLY SPECIES TO HAVE BEEN THROUGH A STONE AGE?
The Stone Age might conjure up images of early humans, sitting around a campfire or hunting prehistoric beasts, but evidence shows that we're not the only species that has learned how to work with stone tools. Wild chimpanzees (Pan troglodytes) use stone tools to crack open nuts.
Should we scrap daylight saving time?
Most of us look forward to the extra hour we get in bed every October, but researchers argue that changing the clocks twice a year harms our health
THE INTERNET OF ANIMALS
SCIENTISTS ARE USING ELECTRONIC TAGS AND SATELLITES TO TRACK WILD ANIMALS AND CREATE A DATA NETWORK THAT COULD HELP US ADDRESS THE BIODIVERSITY CRISIS
MUSIC FOR A DISTRACTED GENERATION
The number of things competing for our attention is often overwhelming. Can dreamy soundscapes created with neuroscience help our bewildered brains to concentrate?
