This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

The dot and cross diagram shows that a water molecule is made up of one oxygen atom joined to two hydrogen atoms, so the formula of water is H 2 O. A nitrogen molecule is made up of two nitrogen atoms ...

The formula is H 2 O so the dot and cross diagram includes two H atoms and one O atom. H has 1 outer electron. O has 6 outer electrons. The H circles must each overlap the O circle. Nitrogen molecules ...

Our bodies are made up of countless cells, and each one is enclosed by a thin layer called the cell membrane. This membrane is not a rigid wall, but a soft, flexible sheet made of lipids. Beneath it ...

Computational modeling could improve how scientists and planners understand and prepare for natural disasters on our coasts and even inland. In an article published in the International Journal of ...

Abstract: Field-control-based nanorobotic manipulation of ions at the single atomic level is an enabling technique for such applications as in-situ prototyping and characterization for fundamental ...

The art of finding patterns or communities plays a central role in the analysis of structured data such as networks. Community detection in graphs has become a field on its own. Real-world networks, ...

Sep. 12, 2025 — Physicists have achieved a breakthrough by using a 58-qubit quantum computer to create and observe a long-theorized but never-before-seen quantum phase of matter: a Floquet ...

Sep. 18, 2025 — Faint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish ...
