Investigation reveals global fisheries are in far worse shape than we thought—and many have already collapsed

Investigation reveals global fisheries are in far worse shape than we thought—and many have already collapsed

Numbers of jackass morwong have plummeted. Credit: Graham Edgar, CC BY When fish are taken from our oceans faster than they can reproduce, their population numbers decline. This over-fishing upsets marine ecosystems. It’s also bad for human populations that rely on fish for protein in their diets. To manage fishing areas sustainably, we need accurate … Read more

But scientists are getting closer to finding it

Credit: Matthew Kapust / Sanford Underground Research Facility Most of the matter in the universe is missing. Scientists believe around 85% of the matter in the cosmos is made of invisible dark matter, which has only been detected indirectly by its gravitational effects on its surroundings. My colleagues and I—a team of some 250 scientists … Read more

Data from space probes show that Alfvén waves drive the acceleration and heating of the solar wind

Data from space probes show that Alfvén waves drive the acceleration and heating of the solar wind

NASA’s Parker Solar Probe and ESA’s Solar Orbiter missions measuring the same stream of plasma flowing away from the sun at different distances. Parker measured copious magnetic waves near the edge of the corona (the “Alfvén surface”), while Solar Orbiter, located past the orbit of Venus, observed that the waves had disappeared and that their … Read more

Hunt for rare bird shows how Ecuador narco violence impedes research

Mario Yanez, another biologist from Inabio, said his current work revolves around finding ‘windows of opportunity’ to continue researching despite the violence. Biologist Cesar Garzon was searching for a small, endangered parakeet in southern Ecuador when he was warned he may be kidnapped, highlighting the danger for scientists in the biodiverse country engulfed in narco … Read more
