Back from the dead: Some corals regrow after 'fatal' warming
  • 38% of coral colonies, lost to a heat wave in 2003 around Spain’s Columbretes Islands, show signs of regrowth.
  • This finding is promising in terms of saving coral reefs around the world.
  • Coral is made of thousands of tiny creatures called polyps which, in the damaged coral, shrunk and gradually -- over several years -- grew into new formations.
  • It’s the first time that this phenomenon was observed and it gives hope.
  • However, the regrowth is still too slow, ~3 millimeters per year, considering that heat waves are happening more often.

We can tell where a whale has travelled from the themes in its song
  • Whales sing different songs in different regions of the world, and whales that pass through a new place also learn its song.
  • By recording whale songs in different locations and breaking them down, researchers identified three distinct song types from 52 whales.
  • Type 1 dominated the central Pacific, type 2 was common in the west, and type 3 was only heard near eastern Australia.
  • This means that scientists can pinpoint where a whale has come from by the song its singing.

Humans haven’t just changed what dogs look like—we’ve altered the very structure of their brains
  • Profound insights from new study show that humans have influenced the development of dog brains -- not just their looks and physical traits.
  • Analysis of MRI brain scans from 62 purebred dogs uncovered six networks in dog brains that varied from dog to dog, depending on what they were bred for.
  • For example, police dogs had differences in the sight and smell network, and fighting dogs showed alterations in the stress response and anxiety network.
  • The study shows that we have a greater influence on the beings around us than we thought.

Clever crows
  • Cleverly designed experiment on 15 Caledonian crows shows that animals can enjoy using tools to solve tasks.
  • Series of tests have shown that crows are more optimistic after tool use.
  • It suggests that there’s much more going on in their heads than we thought, and they can enjoy problem-solving just like humans do.
  • Study author hopes these findings will be used to improve the enclosures of captive animals by adding complex, species-specific enrichment.

Trendy e-scooters might not be as green as they seem
  • E-scooters can benefit your local environment only if you use them instead of your car.
  • Mining materials for them, and manufacturing these vehicles generates pollution.
  • So does collecting them and transporting them to charging stations, which is usually done by employees in private cars.
  • If you don’t use e-scooters to replace your vehicle, then it’s less carbon intensive to just walk or bike.
