Mars landscapes misread as trees sparks new NASA view
NASA scientists say dark patches on Mars resemble trees but are patches of exposed sand among frost.

Scientists caution against picturing real vegetation on the red planet.

Invasive species threaten ecosystems across the U.S.
The rise in global trade has spurred a bioinvasion, with species like purple loosestrife zebra mussel Asian long horned beetle and leafy spurge spreading from coastal ports to the Great Plains. These aliens disrupt habitats, damage agriculture and threaten native wildlife, causing billions in losses.
