In the image above, a faint trail of stars can be seen stretching across the galaxy. These structures, known as globular cluster stellar streams, are coherent stellar structures that retain a record of their dynamical history and can provide unique insights into the evolution of galaxies and the nature of dark matter.

DNA research highlights the genetic vulnerability of Asian elephants

The DNA of Asian elephants tells a concerning story. Although all four subspecies are under pressure, there are considerable differences in their genetic health. In an article published in the journal Genome Biology and Evolution, researchers show how whole-genome analyses can help identify more precisely which populations are most vulnerable and where conservation measures could have the greatest impact.

Severe weather now a key predictor of where bird species occur in North America

Scorching heat waves, severe cold snaps and other extreme weather events are limiting where species can exist—and affecting biodiversity estimates—for more than 500 North American bird species, according to a new, Yale–led study. The issue is particularly acute in the Great Plains and southwestern regions of the United States, where species ranges and total species counts are significantly overestimated when variable and extreme weather are not considered, the study says.
