DNA from old ants reveals a hidden insect apocalypse in Fiji

Insects are essential for ecosystems, but mounting evidence suggests many populations are collapsing under modern pressures. A new study used cutting-edge genomic techniques on museum specimens to track centuries of ant biodiversity across Fiji. The results reveal that nearly 80% of native ants are in decline, with losses intensifying in the past few hundred years as human activities expanded.

Structural protein essential for ciliary harmony in comb jellies

Researchers have identified a structural protein that is essential for the coordinated beating of millions of tiny cilia on the surface of comb jellies. When the protein was eliminated, the cilia began beating out of formation, stalling the locomotion of the jellies. These findings will help uncover how various organisms have adapted to life in different aquatic environments.

New portable DNA sequencer quickly and accurately diagnoses wheat viruses

A group of scientists have developed a new technology that makes it possible to rapidly identify viruses in wheat fields with a significantly higher accuracy. They collected four wheat samples from western Kansas and used a new harmonica-sized DNA sequencer and a computer program to quickly detect three different viruses in the samples. Furthermore, their results suggested that the samples contained a new virus strain.

Volcanic ash sparks a new discovery

Imagine you're getting ready to fly to your favorite vacation destination when suddenly a volcano erupts, sending massive amounts of volcanic ash into the atmosphere, and forcing the cancellation of your flight. That's exactly what happened in April 2010 when Eyjafjallajokull, a volcano in Iceland, erupted and disrupted air travel in Europe for 6 days. Scientists are now using plasma physics to predict the characteristics of these hazardous ash plumes.

California's crashing kelp forest

First the sea stars wasted to nothing. Then purple urchins took over, eating and eating until the bull kelp forests were gone. The red abalone starved. Their fishery closed. Red sea urchins starved. Their fishery collapsed. And the ocean kept warming. This ecological horror story movie took place between 2013-2017, with lasting impacts. This study chronicles the catastrophic shift in 2014 from a robust bull kelp forest to a barren of purple sea urchins.
