  • Breugnathair elgolensis gen. et sp. nov., an early squamate identified from a newly discovered Middle Jurassic skeleton on the Isle of Skye, provides new evidence on the origins of snakes.

  • Progressive apraxia of speech (PAOS) is a neurodegenerative syndrome of multiple etiologies which affects spoken communication. Here, the authors characterized the molecular pathology, biochemistry, genetics and longitudinal neuroimaging of 32 autopsy-confirmed patients with PAOS who were followed over 10 years.

  • The conversion of a soluble protein into polymeric amyloid structures is poorly understood. Here the authors report that the tumor suppressor protein p16INK4a changes its structure upon oxidation to form aggregated amyloid fibrils, which are fully reversible upon disulfide bond reduction.

  • Due to the pulsed nature of X-ray free electron laser (XFEL) instruments the majority of protein crystals, which are injected using continuous jet injection techniques are wasted. Here, the authors present a microfluidic device to deliver aqueous protein crystal laden droplets segmented with an immiscible oil and demonstrate that with this device an approx. 60% reduction in sample waste was achieved for data collection of 3-deoxy-D-manno-octulosonate 8-phosphate synthase crystals at the EuXFEL.

  • The origin of the unique turtle lung ventilatory apparatus is poorly understood. Here the authors show an increase in body wall rigidity early in evolution that allowed the abdominal muscles to become specialized for breathing and the ribs to eventually form the iconic turtle shell.

  • The new European X-Ray Free-Electron Laser (EuXFEL) is the first XFEL that generates X-ray pulses with a megahertz inter-pulse spacing. Here the authors demonstrate that high-quality and damage-free protein structures can be obtained with the currently available 1.1 MHz repetition rate pulses using lysozyme as a test case and furthermore present a β-lactamase structure.

  • What is the best way for predators to find food when prey is sparse and distributed unpredictably? Theory predicts that in such circumstances predators should adopt a Lé-flight strategy, in which short exploratory hops are occasionally interspersed with longer trips. When prey is abundant, simple Brownian motion should suffice. Now, analysis of a large data set of marine predators establishes that animals do indeed adopt Lévy-flight foraging when prey is sparse, and Brownian episodes when prey is abundant.
