00:47 An automated way to monitor wildlife recoveryTo prevent the loss of wildlife, forest restoration is key, but monitoring how well biodiversity actually recovers is incredibly difficult. Now though, a team have collected recordings of animal sounds to determine the extent of the recovery. However, while using these sounds to identify species is an effective way to monitor, it’s also labour intensive. To overcome this, they trained an AI to listen to the sounds, and found that although it was less able to identify species, its findings still correlated well with wildlife recovery, suggesting that it could be a cost-effective and automated way to monitor biodiversity.

00:49 What caused the Universe to become fully transparent?Around 13 billion years ago, the Universe was filled with a dense ‘fog’ of neutral hydrogen that blocked certain wavelengths of light. This fog was lifted when the hydrogen was hit by radiation in a process known as...
The phenomenon of animals catching diseases from humans, called reverse zoonoses, has had a severe impact on great ape populations, often representing a bigger threat than habitat loss or poaching.
However, while many scientists and conservationists agree that human diseases pose one of the...
