Phys.org / Recovery of unique geological samples sheds light on formation of today's Antarctic ice sheet
In recent years, global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root ...

Phys.org / Phage viruses, used to treat antibiotic resistance, gain advantage by cutting off competitors' reproduction ability
Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don't seem to have a role to play in the competition for survival, or so researchers thought.
