The vision of mining space for resources is no longer science fiction. The moon's proximity to Earth and the presence of precious resources make it an increasingly attractive prospect for exploitation.
The Jahn-Teller effect, proposed by Jahn and Teller in 1937, describes how molecules or crystals with degenerate electronic orbitals can lower their total energy by distorting their structure. This distortion lifts the degeneracy, stabilizing certain orbitals that become
When two homozygous plant lines with different characteristics are crossed, the resulting offspring are often more robust and productive than their parents. This phenomenon is called heterosis. It can be caused by positive variants of genes that dominate negative ones, or by
Some wildfires are so intense, they create their own weather—thunderstorms driven by heat that hurtle smoke as high as 10 miles into the sky like giant chimneys.
More than a decade after the first Neanderthal genome was sequenced, scientists are still working to understand how human-specific DNA changes shaped human evolution.
