The Axolotl Can Rebuild Its Own Brain — Here Is How Scientists Think It Works
With feathery gills and a permanent smile, the axolotl looks harmless. But this little salamander holds one of biology's biggest mysteries: the ability to regenerate parts of its own brain.
Do Insects Feel Pain? New Cricket Study Suggests the Answer Might Be Yes
When researchers applied a warm probe to cricket antennae, the insects carefully groomed the sore spot for a long time — behaviour scientists say could be a sign of real pain. Here is what the discovery means for how we think about tiny creatures.
