[Sigfpe on angles and transcendentals] The issue is that the word ‘angle’ has two meanings. One sense of the word ‘angle’ is a set of equivalence classes of intersections between two lines. The pair…

Heme is a circlet of atoms that hold an iron atom much as a setting holds the diamond in a ring. The body needs iron because it easily accepts and donates electrons, which makes it useful for all…

Now we’re using a special type of DNA-linking device — a kind of ‘smart glue’ — that affects how the particles connect to make structures that are switchable between different configurations,”

The koalas communicate across the Australian forests by making low-frequency calls that are shockingly uncute (listen to the embedded video). The upside to the sounds is that they can travel longer…
