A ruinous hailstorm in Spain may have been supercharged by warming seas
Giant hail that pummeled northeast Spain in August 2022 could not have formed without climate change, computer simulations suggest.

How a sugar acid crucial for life could have formed in interstellar clouds
Computer calculations and lab experiments have revealed a possible mechanism for the creation of glyceric acid, which has been seen in meteorites.
- Life
This is the first egg-laying amphibian found to feed its babies ‘milk’
Similar to mammals, these ringed caecilians make a nutrient-rich milk-like fluid to feed their mewling hatchlings up to six times a day.

A vaccine for bees has an unexpected effect
Honeybees vaccinated against a bacterial disease were also protected from a viral disease.

A fiber inspired by polar bears traps heat as well as down feathers do
Scientists took a cue from polar bear fur to turn an ultralight insulating material into knittable thread.
- Planetary Science
Our picture of habitability on Europa, a top contender for hosting life, is changing
The moon of Jupiter is considered one of the most promising places to look for life, but its subsurface ocean may be less habitable than once thought.
- Animals
The Brazilian flea toad may be the world’s smallest vertebrate
Brazilian flea toads are neither a flea nor a toad, but they are almost flea-sized. The frogs are small enough to fit on a pinkie fingernail.

Here’s how tardigrades go into suspended animation
A new study offers more clues about the role of oxidation in signaling transitions between alive and mostly dead in tardigrades.
- Anthropology
50 years ago, evidence showed that an extinct human ancestor walked upright
Fossil finds have since pushed back the ability of hominids to walk on two legs by millions of years.
- Archaeology
These South American cave paintings reveal a surprisingly old tradition
Radiocarbon dates point to an artistic design practice that began in Patagonia almost 8,200 years ago, several millennia earlier than previously recorded.

Male dragonflies’ wax coats might protect them against a warming climate
The reflective wax, which cools males on sunny courtship flights, may also armor them against the effects of climate change.
- Genetics
A genetic parasite may explain why humans and other apes lack tails
Around 25 million years ago, a stretch of DNA inserted itself into an ancestral ape’s genome, an event that might have taken our tails away.
