Femtosecond laser ablation permits non‐invasive surgeries in the bulk of a sample with
submicrometer resolution. We briefly review the history of optical surgery techniques and the …

In animals, proper locomotion is crucial to find mates and foods and avoid predators or
dangers. Multiple sensory systems detect external and internal cues and integrate them to …

Analysis of Neandertal DNA holds great potential for investigating the population history of
this group of hominins, but progress has been limited due to the rarity of samples and …

The desert-dwelling sandfish (Scincus scincus) moves within dry sand, a material that
displays solid and fluidlike behavior. High-speed x-ray imaging shows that below the …

Worm-like filaments that are propelled homogeneously along their tangent vector are
studied by Brownian dynamics simulations. Systems in two dimensions are investigated …

Alternative patterns of neural activity drive different rhythmic locomotory patterns in both
invertebrates and mammals. The neuro-molecular mechanisms responsible for the …

The effects of fluid elasticity on the swimming behavior of the nematode Caenorhabditis
elegans are experimentally investigated by tracking the nematode's motion and measuring …

To navigate different environments, an animal must be able to adapt its locomotory gait to its
physical surroundings. The nematode Caenorhabditis elegans, between swimming in water …

Many animals, including humans, select alternate forms of motion (gaits) to move efficiently
in different environments. However, it is unclear whether primitive animals, such as …

PVD and FLP sensory neurons envelope the body of the C. elegans adult with a highly
branched network of thin sensory processes. Both PVD and FLP neurons are …
