How Roots Push Through Compacted Soil

Soil compaction from heavy machinery and drought makes farming harder. Researchers found how roots thicken, swell and reinforce their outer layer so they can push into dense soil; a protein (a transcription factor) helps this process.

Hair can record chemical exposure

Researchers at the University of Texas at Austin found that human hair stores a timeline of chemical exposure. By heating intact strands and scanning the released molecules, the team reconstructed past exposures that blood or urine cannot show.
