Expanded susceptibility and transmission in circulating avian influenza viruses reshape wild bird mortality

Internal changes due to the sun's "active biorhythm" have become increasingly "skin-deep" over the past four solar activity cycles, according to a new study.

A decade ago, Bradley Markle, an assistant professor at the Institute of Arctic and Alpine Research at the University of Colorado Boulder, noticed an odd pattern while sifting through temperature records from the end of the last ice age in Antarctica. The records seemed to defy prevailing theories of how temperatures vary across the Antarctic continent.

Persistent methane emissions from sectors such as agriculture and growing debates over the credibility of carbon offsets are creating new challenges for governments and companies pursuing net-zero commitments. New research suggests that temporary carbon storage may have a scientifically valid role in helping support climate goals, if used in the right way.

When a team of researchers recorded a low thundering underneath the surface of the Hudson River, they thought they were hearing the muffled rumble of trains. A closer look and listen led to a much more interesting discovery: The thunder came from Atlantic sturgeon—an iconic and endangered species—spawning in the depths of the river.
