Flight system of flies is driven by wings and mechanosensory halteres that operate as independently driven but coupled oscillators, thereby imparting robustness against wing or thorax damage.

Newly recovered lumbar vertebrae belonging to Malapa Hominin 2, an adult female of the fossil hominin species Australopithecus sediba, demonstrate that this individual was adapted to upright posture and bipedal locomotion but also had adaptations for climbing in trees.

Socially exchanged fluids passed mouth-to-mouth in ant colonies contain protein signatures of colony maturity and individual behavioral role, indicating that this fluid may underlie a distributed metabolism that functions over the scale of the colony.

The protein components of an essential and conserved meiotic interface, the synaptonemal complex, have highly conserved coil-coiled domains and protein length, despite highly diverged sequence.

Comparative study provides evidence that males are under stronger total selection compared to females.

Developing Monosiga brevicollis as a model to study choanoflagellate immune responses reveals that the innate immune protein STING mediates responses to cyclic dinucleotides in choanoflagellates, providing insight into the evolution of STING signaling on the animal stem lineage.

Permian xylophagous beetles suffered a severe extinction during the end-Permian mass extinction largely due to the collapse of forest ecosystems.

A 'hotspot' position in an olfactory receptor protein family underlies changes in odor tuning in different receptors at different times during evolution.

Experimentally evolved budding yeast populations reveal the role of contingency and chance in shaping the emergence and dynamics of pleiotropic effects of adaptation.

Intergenerational adaptations to stress play a critical role in organismal responses to changing environments and are largely lost or erased after one generation.
