Scientists discover hidden “winds” inside cells that could explain cancer spread
Researchers have uncovered a previously unknown system of internal currents inside cells that actively transport proteins to where they're needed, overturning long-held assumptions about how cells function. These "cellular winds" appear to accelerate cell movement and repair by directing materials toward the leading edge of the cell. The discovery could be a critical missing piece in understanding why certain cancer cells metastasize with unusual speed.

Scientists just found DNA “supergenes” that speed up evolution
Researchers studying cichlid fish in Lake Malawi have identified chromosomal inversions—flipped sections of DNA that bundle advantageous gene combinations into so-called "supergenes"—as a key driver of rapid speciation. These genetic structures lock in winning trait combinations, allowing populations to adapt quickly to distinct environments without beneficial genes being scrambled by reproduction. The finding offers a compelling mechanism for one of evolution's longest-standing puzzles: how hundreds of species can emerge in a geological blink.
