Scientists look to hack photosynthesis for a ‘greener’ planet
Photosynthesis turns sunlight into energy for plants. Scientists want to know more about it, imitate it — even improve it.
- Animals
Piranhas and plant-eating kin replace half their teeth at once
Piranhas and pacus shed and replace half of their teeth at a time. New teeth lock together as they push up from the jaw.
- Life
A new spin on lab-grown meat
A technique inspired by how cotton candy is spun could help produce lab-grown meat at a lower cost and on a bigger scale.
- Animals
Blood vessels in their heads kept big dinos from overheating
Giant dinosaurs evolved several ways to cool their blood and avoid heatstroke.

Scientists Say: Octopod
These marine animals have soft bodies and eight sucker-lined arms. Some are known for their smarts or ability to quickly change colors.
- Animals
Fossils show mammals’ rise to dominance after the dino-killing asteroid
What happened to mammals after an asteroid wiped out the dinosaurs? Newfound fossils show how they grew in size, eventually dominating much of life on Earth.
- Animals
Weird little fish inspires the development of super-grippers
Suction-cup designers were inspired by the rock-grabbing tricks of the aptly named clingfish.
- Climate
Powerful storms may be causing ‘stormquakes’ offshore
A perfect-storm mixture of hurricane, ocean and seafloor structures can create distinct seismic signals that have now been named ‘stormquakes.’
- Physics
Scientists Say: Power
This word describes the rate at which energy is delivered or used to do work, along with related ideas, such as ways of making electricity.
- Animals
Humpback whales catch fish using bubbles and flippers
Scientist for the first time have captured details of humpback whales’ hunting tactics on camera.
- Chemistry
Chemistry’s ever-useful periodic table celebrates a big birthday
2019 is the International Year of the Periodic Table. But the traditional chart is just one of many shapes that chemists and other scientists have developed to organize the elements.
- Physics
Frozen’s ice queen commands ice and snow — maybe we can too
In the Frozen movies, Elsa magically manipulates snow and ice. But scientists, too, make snowflakes. If they reinforce it, architects can build with ice and snow.
