Scientists Say: Mass
Mass shows how much an object resists speeding up or slowing down when force is applied — a measure of how much matter is in it.

Let’s learn about plastic pollution
The world is cluttered with plastic waste. All that junk kills animals far and wide.

Abdominal fuzz makes bee bodies super slippery
Scientists find that tiny hairs on a honeybee’s abdomen reduce wear and tear as a bee’s outer skeletal parts rub against each other all day long.

Uncovering secrets of the glasswing butterfly’s see-through wings
The tricks of its transparency include sparse, spindly scales and a waxy coated membrane.

Spin in this Milky Way bar may show cosmic dark matter does exist
A method akin to studying a tree’s rings reveals the timeline of a slowdown in those stars at the heart of our Milky Way galaxy.

Birds could get their sense of direction from quantum physics
Songbirds could detect north and south using a protein in their eye. It works somewhat like a compass.
- Physics
Nuclear clocks are nearly here
More precise clocks could improve technologies such as GPS and help scientists test major ideas in science.
- Physics
Light from space has record-breaking energy
Hundreds of newly detected gamma rays hint at environments in the cosmos that accelerate particles to energy extremes.

‘Smart’ pasta morphs into fun shapes as it cooks
The trick to this shape-shifting are grooves cut into the raw pasta. Those grooves affect how the noodles swell as they cook.

Stars made of antimatter could lurk in our galaxy
Fourteen sources of gamma rays in our galaxy look like they could be antistars — celestial bodies made of antimatter.

Scientists Say: Bond
In chemistry, this attachment between atoms forms because of the power of attraction. Chemical bonds make up every solid object on Earth.

The pebbled path to planets
Small pebbles zipping through a sea of gas may give rise to mighty planets.
