Pacific trade winds stall global surface warming -- for now

Researchers find Pacific trade winds have driven more heat into oceans, slowing global warming; however, when winds weaken, heat will rapidly return to atmosphere. The study suggests a hiatus in global warming is temporary and temperatures will soon rise rapidly.

Fight or flight? Vocal cues help deer decide during mating season

Researchers found that fallow bucks respond differently to fast vs. slow rate groans, indicating they signal aggression through calling speed. Bucks also recognize early-rut groans as more threatening than late-rut ones, helping them avoid exhausted rivals during mating season.
