A bit of electricity can glue hard metals to soft materials
Using this method to stick and unstick metals from soft materials could one day create new types of batteries.

The movie Frozen inspired the icy, 3-D printing of blood vessels
Ice guides a 3-D printing method to make realistic, artificial blood vessels. One day, such vessels could be used in lab-grown organs.

Turning jeans blue with sunlight might help the environment
When dipped in indican and exposed to sunlight, yarn turns a deep blue. This process is more eco-friendly than the current denim dyeing method.

Explainer: What is the solar cycle?
Here’s what causes the sun’s 11-year cycle of activity and what it means for us on Earth.

Forests could help detect ‘ghost particles’ from space
If trees could act as natural antennas, one physicist proposes that they just might pick up signals of hard-to-spot ultra-high energy neutrinos.

Here’s why blueberries aren’t blue — but appear to be
Blueberries actually have dark red pigments — no blue ones — in their skin. Tiny structures in the fruits’ waxy coat are what make them seem blue.

The weird sky glow called STEVE is really confusing scientists
Researchers are trying to figure out the recipe of atmospheric conditions that creates this aurora-like light show.
