Matter and Its Interactions
- Materials Science
These colorful butterflies were printed with transparent ink
Clear ink creates a whole rainbow of colors when printed in precise, microscopic patterns. This phenomenon is known as structural color.
- Physics
Scientists Say: Convection
Convection is a process that transfers heat through the movement of liquid or gas.
- Tech
Scientists find a ‘greener’ way to make jeans blue
When coated onto jeans, a plant-based polymer reduces water and cuts the amount of toxic chemicals needed.
- Chemistry
Chemistry solves a French royal mystery
Ink analysis reveals the hidden words of Marie Antoinette's letters and who tried to hide them.
- Environment
Everyday plastics can pollute, leaching thousands of chemicals
Plastic bags and containers leach potentially toxic chemicals into both food and water, but researchers yet don’t know how they might affect health.
- Materials Science
Bacteria make ‘spider silk’ that’s stronger than steel
Part spider silk, the material is better than what some spiders make. Researchers think it might make the basis for surgical threads or unusually strong fabrics.
- Agriculture
Potty-trained cows could help reduce pollution
About a dozen calves have been trained to pee in a stall. Toilet training cows on a large scale could cut down on pollution, scientists say.
- Chemistry
Scientists Say: Electron
Electrons are negatively charged particles. They are attracted to the positively charged particles in the center, or nucleus, of an atom.
- Chemistry
Chemists win Nobel Prize for faster, cleaner way of making molecules
Both scientists independently came up with new process — asymmetric organocatalysis. That name may be a mouthful, but it’s not that hard to understand.
- Plants
Well-known wildflower turns out to be a secret meat-eater
Look closely at Triantha occidentalis, and you’ll see gluey hairs — and a trail of insect corpses on its stem.
- Tech
Synthetic trees could tap underground water in arid areas
They also could also help coastal residents mine fresh water from salty sources.
- Physics
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.
