Safer CRISPR gene editing with fewer off-target hits

The CRISPR system is a powerful tool for the targeted editing of genomes, with significant therapeutic potential, but runs the risk of inappropriately editing ”off-target” sites. However, a new study shows that mutating the enzyme at the heart of the CRISPR gene editing system can improve its fidelity.

Animals who try to sound ‘bigger’ are good at learning sounds

Some animals fake their body size by sounding ‘bigger’ than they actually are. Researchers studied 164 different mammals and found that animals who lower their voice to sound bigger are often skilled vocalists. Both strategies — sounding bigger and learning sounds — are likely driven by sexual selection, and may play a role in explaining the origins of human speech evolution.

Simulations shows magnetic field can change 10 times faster than previously thought

(University of Leeds) A new study by the University of Leeds and University of California at San Diego reveals that changes in the direction of the Earth’s magnetic field may take place 10 times faster than previously thought.

MOSAiC floe: Sea ice formation

The New Siberian Islands were the birthplace of the MOSAiC floe: the sea ice in which the research vessel Polarstern is now drifting through the Arctic was formed off the coast of the archipelago, which separates the East Siberian Sea and the Laptev Sea to the north of Siberia, in December 2018.

The latest findings on the MOSAiC floe

(Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research) The New Siberian Islands were the birthplace of the MOSAiC floe: the sea ice in which the research vessel Polarstern is now drifting through the Arctic was formed off the coast of the archipelago, which separates the East Siberian Sea and the Laptev Sea to the north of Siberia, in December 2018.
