Are Texas Blackouts a Warning About the Follow-on Effects of Climate Change?
This week in America, “continent-spanning winter storms triggered blackouts in Texas, Oklahoma, Mississippi and several other states,” reports the New York Times. But that was just the beginning… One-third of oil production in the nation was halted. Drinking-water systems in Ohio were knocked offline. Road networks nationwide were paralyzed and vaccination efforts in 20 states were disrupted. The crisis carries a…

Substance Found In Antarctic Ice May Solve a Martian Mystery
sciencehabit shares a report from Science Magazine: Researchers have discovered a common martian mineral deep within an ice core from Antarctica. The find suggests the mineral — a brittle, yellow-brown substance known as jarosite — was forged the same way on both Earth and Mars: from dust trapped within ancient ice deposits. It also reveals how important these glaciers were on…

Is Mars still volcanically active?
A new study of geologically young lava flows in Elysium Planitia suggests that Mars might still have residual volcanic activity below its surface. The finding could also correlate with seismic activity detected by the InSight lander in the same region and may have implications for possible martian life.
