Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different substances, including solids, liquids, and gases that are all ...

These clusters of strongly bonded atoms are called molecules. See how they're represented by two circles of different size and colour that are joined together. This particle diagram represents ...

Students will also be able to explain that since different liquids are made of different atoms and molecules, they act in their own characteristic way. When observing different liquids, the way a ...

mRNA is the most variable class of RNA, and there are literally thousands of different mRNA molecules present in a cell at any given time. Some mRNA molecules are abundant, numbering in the ...

MIT scientists find the protein IL-17 that fights infection also acts on the brain, inducing anxiety or sociability. This adds to evidence that immune molecules can influence behavior during illness.

Using models of the protein, they designed more than a hundred different molecules, which were then produced. When the ...

It has also provided a comprehensive analysis of the expression of snoRNA molecules during development and between different adult animal tissues. "This is the first time that someone has ...

Scientists have determined that the key structural feature that makes these molecules different is the position of their double bonds. The position of these double bonds can be described in ...

NASA's Curiosity Mars rover has detected the largest organic (carbon-containing) molecules ever found on the red planet.

using different experimental techniques, and has shown evidence of clay minerals, as well as the first (smaller and simpler) organic molecules found on Mars, back in 2015. These included several ...

The process of catalysis—in which a material speeds up a chemical reaction—is crucial to the production of many of the ...
