Why plants don't get sunburn

Researchers found that plants produce special molecules called sinapate esters to protect themselves from harsh ultraviolet-B radiation. These molecules appear to block UVB radiation from penetrating deeper into leaves, hindering plant growth. The study provides insight into the mechanics of how these natural plant sunscreens work.

Glacier song

A recent study published in Geology reveals that harmonic tremor occurs within mountain glaciers and that individual icequakes can exhibit harmonic properties. This discovery suggests a complex network of fluid-induced fracture processes at the glacier base, which can lead to damaging floods in valleys below the glacier.

Pair bonding reinforced in the brain

Researchers found that zebra finch pairs utilize their innate calls for bonding and cohesion, with brain activity correlating to these calls. This suggests an evolution of songbirds' brain regions from simple vocalization systems to specialized networks for learned songs.
