- Chemistry
Scientists Say: Plasma
In physics, plasma refers to one of the four states of matter. In medicine, plasma describes the part of blood that ferries cells, nutrients and more throughout the body.

Tiny swimming robots may help clean up a microplastics mess
Big problem, tiny solution. Researchers in the Czech Republic have designed swimming robots that can help collect and break down microplastics.
- Chemistry
Scientists Say: Aerosol
Aerosols are tiny bits of solids or drops of liquids suspended in gas. Aerosols include mist, fog and soot, as well as pollution from fossil fuels.

Take a look at this weird, bendy type of ice
These specially grown threads of ice bend into curves, then spring back when released.
- Physics
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.
- Environment
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.
