European rainforest
The largest national park in the European Union is in South America.
Cat-in-chief
Who rules the cats of England? Since at least the 1920s, 10 Downing Street has had an official cat: the Chief Mouser to the Cabinet Office.
Underwater unknown
A strange honeycomb pattern appears on sea ridges around the world. We think that it is created by living creatures, but no-one has ever seen one. Oh, and there are fossils of the patterns going back 500 million years.
Plastic-eating bacteria
In 2016, Japanese scientists discovered a new and unique type of bacteria outside a recycling factory in Sakai. It can eat plastic.
Prospecting plants
You can search for gold the easy way, with a pan or a pickaxe. Or you could examine the local Eucalyptus trees. This is geobotanical and biogeochemical prospecting.
Second-fastest animal
Everyone knows that the cheetah is the fastest land animal in the world – but what’s the second-fastest? And why is it so fast?
Stomach tadpoles
Remember those fish that raise their children inside their mouths? Two Australian frog species went even further: they raised tadpoles in their stomachs.
Hyperparasites
Parasites live off – and often on – other animals. But what live on the parasites?
Great Green Wall
It’s no surprise that one of the ways we’ll fight climate change is to plant a lot of trees. Across the entirety of northern Africa, millions of trees are being planted to help, and also to hold back the spread of the Sahara.
Elephant justice
Topsy the elephant was famously electrocuted in 1903. History has not been kind to her, so let’s set the record straight. No, she was not a victim of the AC vs. DC wars. No, she was not a killer elephant. Yes, she killed one man, but in clear self defence.
Cuckoo bees and cuckoo fish
Cuckoos are not the only animal to have their young raised by other species. Bees, wasps, and fish also exhibit the same parasitic behaviour.
Learned pig
Before television, people had to make their own fun. So they trained pigs to read.
Whale snot drone pilots
Everyone dreams of being a scientist, but few understand just what that profession entails. Well, among other things, you could be a whale snot drone pilot.
Elf ring
Ever see a set of mushrooms growing in a near-perfect circle? Or an arc of dead or dark grass on a green field? Folklore calls it the elf ring or fairy ring, but it actually has a very reasonable biological explanation.
Immortal dog
Some time more than 200 years ago, a dog or wolf in China or Siberia got cancer. It was a strange type of cancer: the cancer cells were contagious. That cell line is still alive today, and will probably be alive forever.
