Animals don’t have to die for exotic leather products. It is, however, perfectly legal to use tusks from extinct mammoths for making luxury wood carvings, chess figures or jewellery. Since this type of ivory is mostly extracted from permafrost regions or near Polar seas, many elephants fall victim to the illegal ivory trade. It is impossible to make out...

Monitoring the fish population could prevent overfishing. Where industrial fishing is concerned, however, there is still room for improvement. Using satellite images and vessel GPS trackers, a US-based non-profit organisation collated 2 million gigabytes of data spanning the years 2017-2021. Data harnessed, in turn, to train an artificial intelligence that could map vessel activities and offshore infrastructure such as...

Birds use the earth’s magnetic field as their compass. But how do animals perceive their surroundings in general? Tortoises and insects such as bees can differentiate between red, blue and green and see ultraviolet light. Snakes can recognise infrared light. With dogs and cats, meanwhile, it’s only shades of blue and green. Animals also experience different intensities and gradations...

Image analysis can find hidden ruins or save elephants’ lives. But that’s just the start. A female-led startup in Nairobi is using satellite images and artificial intelligence to strengthen the continent’s agriculture industry. After all, around 60% of sub-saharan Africa’s jobs are dependent on it - most of them smallholders significantly impacted by climate change. The machine-based image analysis...

Donations left by a desert robot could help create an oasis. The same cannot be said, however, for humans leaving their “mark” and their tissues in nature. Enter an Israeli design student’s sustainable toilet paper. Made from oranges and aloe vera, each individual leaf is woven with plant seeds such as mint, rose or parsley. Though thicker than traditional...

Wind turbines warn birds about deadly collisions. Lions, meanwhile, are often shot to protect farm animals, and ensure smallholders have food on their plates. In the last 20 years, however, the lion population in Africa has reduced by half. Now a resourceful Maasai founder and his startup are looking to arrest this decline through a solar electricity-powered light system....

Building elements filled with seeds and surfboards containing straw are allowing nature to grow. Now, a Hong Kong-based startup is 3D printing hexagonal tiles from clay which are installed on the seafloor and planted with young coral. A coral-specific algorithm tells a robotic arm how to print the tiles' labyrinthine structure. This not only promotes growth but enables corals...

Documenting fish stocks makes commercial fishing more sustainable. But certain organisms such as fast-growing algae create havoc for aquatic ecosystems. They deprive fish of their basis for life. Water fleas feed on algae, however, and thus have a positive impact on the natural order of things. Selecting four different genotypes of water flea, a female student from Canada examined...
