• Europe's most active volcano may have a secret origin

  Mount Etna has long puzzled geologists because it doesn't fit any of the three classic ways volcanoes are thought to form. A new study suggests it may instead be fueled by ancient pockets of magma that are pushed upward through cracks created by shifting tectonic plates. If confirmed, Etna could belong to a rare fourth category of volcano, revealing that much larger volcanoes can form through processes previously associated only with small submarine eruptions.

• This common pesticide may be quietly wiping out future bumblebees

  A next-generation pesticide designed to kill crop pests may also be interfering with the reproductive health of bumblebees. Researchers discovered that low-dose exposure to sulfoxaflor changed gene activity, especially in tissues involved in reproduction, raising concerns about long-term impacts on bee populations. Because pollinators are essential for about one-third of the world's food production, finding ways to protect them while controlling pests has become increasingly important.

• Hawaii's famous “happy-face” spider has a surprising relative

  A newly discovered Happy-Face spider in the Himalayas closely resembles Hawaii's iconic species but evolved independently, according to DNA evidence. Its mysterious smile-like markings, many color forms, and unexpected link to ginger plants have scientists eager to learn how the two distant species are connected.

• Trees keep absorbing carbon long after they stop growing

  Oak trees keep absorbing carbon dioxide long after their annual growth has ended, revealing that photosynthesis and wood production are not as closely linked as scientists once believed. The finding could reshape forecasts of how much carbon forests will be able to store in a warmer future.

• Rare goblin shark filmed alive for the first time in the deep sea

  For the first time, researchers have filmed the elusive goblin shark alive in the deep ocean where it naturally lives. The remarkable sightings greatly expand the shark's known range and depth, showing that this 125-million-year-old "living fossil" still has plenty of secrets left to reveal.
