Animals

A persistent scientific mystery over the past century has been exactly how some animals seemingly have the ability to sense the Earth’s magnetic field. A team of researchers are suggesting the magnetic-sensing bacteria could be symbiotically generating this novel sense.

The oldest known animal sperm sample has been discovered, dating back 100 million years. Dozens of ostracods were found in a piece of amber with their “soft parts” out, and their giant sperm measuring around a third of the animals’ body length.

In a breakthrough that promises to revolutionize the precision breeding of animals, scientists have used the CRISPR gene editing tool to produce infertile animals that become "surrogate sires" and produce sperm containing only donor animal DNA

Lighting, composition, exposure, technique ... None of it matters if your photo can't tell a story and convey emotion – and the finalists from the 2020 Comedy Wildlife Photography Awards each tell a thousand words, and hopefully give you a grin!

We're on the brink of a sixth major extinction event, largely thanks to human activity and climate change. The least we could do is try to prevent some of them, and now a study has quantified how many species we may have saved in the last few decades.

It can be hard to determine if an animal is extinct or just really good at hiding. A new study shows how environmental DNA can help the hunt, with several missing frog species rediscovered in Brazil, including one that hasn’t been seen in 50 years.

Be thankful you didn’t live 20 million years ago, when the seas were patrolled by the Megalodon. This monstrous prehistoric shark was more than twice the size of a great white, and now a new detailed analysis has found just how big it really was.

Liver cells are quick to regenerate, and now researchers have discovered just how persistent those cells can be. In tests in pigs with severe liver damage, functional new backup livers were found to grow in the animals’ lymph nodes.

A long-lost species has been rediscovered alive and well. The Somali sengi, an insect-eating mammal that hasn’t been seen in over 40 years, has turned up in East Africa, with researchers snapping the first-ever photos and video of them in the wild.

All kinds of fascinating discoveries are waiting in the deep sea. Now scientists have pulled a new monster out of the waters off the Indonesian coast. The creature is a new species of “supergiant” isopod, a huge marine relative of the common pillbug.

In April 2020, a bull calf named Cosmo was born to a team of scientists. This probably wouldn’t normally be news except that this particular bouncing baby boy had his genome edited as an embryo, to make him more likely to produce male offspring.

Scientists have discovered ultra-black fish that absorb almost all light that hits them, allowing them to effectively hide in the deepest, darkest parts of the ocean. The find could help inform future advances in optical and camouflage technology.
