Cells manage a wide range of functions in their ... Eventually, when the carbon atoms from a complex organic food molecule are fully oxidized at the end of the reaction chain, they are released ...

Here, travel into the tiny world of DNA, all the way down to the level of the atoms that make up a single DNA base. The human body contains about 100 trillion cells, each working together in a ...

UC Santa Barbara researchers are working to move cold atom quantum experiments and applications from the laboratory tabletop ...

they become unstable free radicals that seek other atoms or molecules to bond to. Free radicals are a natural byproduct of cell metabolism, so it is not possible to avoid them entirely.

When sunlight hits the cells, it knocks electrons loose from their atoms. As the electrons flow through the cell, they generate electricity. On a much larger scale, solar-thermal power plants ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...

Cells are the smallest unit of life. Cells in multicellular plants and animals are arranged into tissues, organs and organ systems. Cells. Tissues. Organs. Organ systems. And the organism itself ...

Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.
