Sea slugs increase the longevity of the chloroplasts they steal from algae by limiting the harmful side-effects of photosynthesis.

Slug chloroplasts avoid damage to photosynthesis by maintaining an oxidized electron transfer chain with the help of oxygen-sensitive electron acceptors.

The discovery of new skeletal remains of Homo naledi in the Lesedi Chamber, South Africa, adds more evidence to our understanding of the morphology and behavior of this recently discovered species.
