Major boost in carbon capture and storage essential to reach 2°C climate target

Large expansion of carbon capture and storage is necessary to fulfill the Paris Climate Agreement. Yet a new study shows that without major efforts, the technology will not expand fast enough to meet the 2 C target and even with major efforts it is unlikely to expand fast enough for the 1.5 C target.

Bacterial 'flipping' allows genes to assume different forms

Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called inversions. A study has now shown that inversions, which cause a physical flip of a segment of DNA and change an organism's genetic identity, can occur within a single gene, challenging a... Read more ›
