If confirmed, tubes in 890-million-year-old rock may be the oldest animal fossils
Pale, wormlike tubes in 890-million-year-old rock may be ancient sea sponges, a new study concludes. If confirmed, that controversial claim would push back the origin of the earliest sponges by…
3.42-billion-year-old fossil threads may be the oldest known archaea microbes
Threadlike filaments pressed in rock may be the remnants of archaea that burped methane near hydrothermal vents 3.42 billion years ago. If so, these strands in rock excavated in South…
Pterosaurs may have been able to fly as soon as they hatched
Pterosaur hatchlings may have been able to fly right out of the shell — although the flight of those ancient baby reptiles might have looked a bit different from that…
The first step in using trees to slow climate change: Protect the trees we have
Between a death and a burial was hardly the best time to show up in a remote village in Madagascar to make a pitch for forest protection. Bad timing, however,…
How Romanesco cauliflower forms its spiraling fractals
The swirling green cones that make up the head of Romanesco cauliflower also form a fractal pattern — one that repeats itself on multiple scales. Now, the genes that underlie…
A widely studied lab plant has revealed a previously unknown organ
A common lab plant that’s been poked and put under microscopes for decades may seem unlikely to keep secrets. But in widely studied Arabidopsis thaliana, scientists have identified the “cantil”…
These ferns may be the first plants known to share work like ants
High in the forest canopy, a mass of strange ferns grips a tree trunk, looking like a giant tangle of floppy, viridescent antlers. Below these fork-leaved fronds and closer into…
‘Tree farts’ contribute about a fifth of greenhouse gases from ghost forests
If a tree farts in the forest, does it make a sound? No, but it does add a smidge of greenhouse gas to the atmosphere. Gases released by dead trees…
Catnip repels insects. Scientists may have finally found out how
A whiff of catnip can make mosquitoes buzz off, and now researchers know why. The active component of catnip (Nepeta cataria) repels insects by triggering a chemical receptor that spurs…
