Sloths once came in a dizzying array of sizes. Here’s why
A new fossil and DNA analysis traces how dozens of sloth species responded to climate shifts and humans. Just two small tree-dwelling sloths remain today.

Seafloor amber may hold hints of a tsunami 115 million years ago
Oddly shaped deposits of tree resin point to massive waves that struck northern Japan roughly 115 million years ago and swept a forest into the sea.

Among chimpanzees, thrill-seeking peaks in toddlerhood
In humans, teens do the most dangerous things. In chimpanzees, that honor goes to toddlers. The difference may lie in caregiver supervision.

In a Quebec park, a science game brings predator-prey dynamics to life
Results show that players’ choices echo predator-prey patterns seen in wildlife, though scientists stress the limits of the analogy.
- Microbes
To make a tasty yogurt, just add ants (and their microbes)
Spiking milk with live ants makes tangy traditional yogurt. Researchers have identified the ants' microbial pals and enzymes that help the process.
- Plants
Plants packed close enough to touch are more resilient to stress
Signals transmitted via leaves can warn neighboring plants of stressful events, making the group collectively more resilient than plants in isolation.

Fires in the Amazon forest may melt sea ice in Antarctica
Satellite data reveal a link between the amount of black carbon in the atmosphere and rates of Antarctic sea ice loss in recent years.
- Archaeology
Neandertals mastered fire-making tools 400,000 years ago
Archaeologists found flint, iron pyrite to strike it and sediments where a fire was probably built several times at an ancient site in England.
- Life
We all have a (very tiny) glow of light, no movie magic needed
Normal cellular processes in living things — from germinating plants to our own cells — create biophotons, though escaping light isn’t visible to us.

An all-female wasp is rapidly spreading across North America’s elms
The elm zigzag sawfly has spread to 15 states in five years. Now it's attacking the tree that cities planted to replace Dutch elm disease victims.
- Archaeology
Humans moved into African rainforests at least 150,000 years ago
This oldest known evidence of people living in tropical forests supports an idea that human evolution occurred across Africa.
- Anthropology
A foot fossil suggests a second early human relative lived alongside Lucy
Foot bones and other fossils have been attributed to Australopithecus deyiremeda, a recently discovered species that may shake up the human family tree.
