Our galaxy, perhaps like many in the universe, is a bit of a Frankenstein’s monster. A new study makes a compelling case that a central structure in the Milky Way is actually composed mostly of stars born in another galaxy, brought to us by a long-ago galactic smash-u ...read more

(Inside Science) — Soil bacteria respond dramatically to changes in climate, but the full impacts aren’t felt for at least half a century, according to new research. The findings suggest that today’s climate conditions will continue to cause upheaval in the soil for decades.
A team of Chinese and American researchers analyzed data from soil samples collected in recent years from 144 sites in Tibet, the U.S. and Canada. Next, they use ...read more
