In what way are cells similar to atoms? Where do killer T-cells develop? Why are animal cells more irregularly shaped than plant cells? Do endothelial cells regenerate? How does mycoplasma spread in cell culture? Why does a cell undergo mitosis?
Molecules are made up of atoms that are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.
As you do so, skin cells that are trillions of atoms thick flake off your hand and flutter down all around it, burying it in a pile of atomic doppelgangers. Meanwhile, moisture and atmospheric particles shoot about, bouncing on and off the scale and sending its atom-sensitive needle ...
Determining the charge of an atom is easy in most cases but not all. Atoms are held together by the electromagnetic forces between the protons in the nucleus and the electrons surrounding it, and this means that most of the time there isn't actually much to work out. But when elements lo...
Making them requires steps that are similar to what it takes to make a photograph: A shutter opens or moves out of the path of a laser. (In some setups, a pulsed laser fires a single pulse of light, eliminating the need for a shutter.) The light from the object beam reflects off ...
The two main types of solar cells are monocrystalline and polycrystalline. The "photovoltaic effect" refers to the conversion of solar energy to electrical energy. The EnergySage Marketplace is a great way to get in contact with solar panel installers near you and start powering your home with ...

Like the SOFC, these fuel cells are also best suited for large, stationary power generators. They operate at over 600 degrees Celsius, so they can generate steam that can be used to generate more power. The cell uses a molten salt solution as a catalyst that separates hydrogen particles from...
Seeing with photons is fine if you want to look at things that are much bigger than atoms. But if you want to see things that are smaller, photons turn out to be pretty clumsy and useless. Just imagine if you were a master wood carver, renowned the world over for the finely carved ...
I like to think of a spiritual connection in scientific terms as well as emotional ones. When two people are spiritually connected they operate on the same spiritual wavelength. They vibrate to the same energy as one another. Remember, all atoms vibrate to their own unique frequency. Imagine ...
