Between 1935 and 1942, a total of 130 men, aged seventeen to twenty-four, mostly of indigenous Hawaiian heritage, colonized Howland, Baker, and Jarvis Islands for the United States, in rotation, over the course of twenty-six expeditions. As part of the American Equatorial Islands Colonization Project (AEICP), they compiled meteorological data, observed and recorded the natural life of their surroundings, collected specimens for the Bishop Museum in Honolulu, mapped the islands, and built a landing strip on Howland for Amelia Earhart. In doing so, they confirmed U.

Article Synopsis
- Limbs are a key feature of tetrapods, but some species, especially amphibians and reptiles, have lost them to adapt to different environments, prompting research into the genetic reasons behind this.
- The study focuses on the Banna caecilian, a limbless amphibian, and compares its genome with other species to identify specific genes related to limb development that have been lost or altered.
- Findings show that both caecilians and snakes have a unique set of conserved genetic elements linked to limb loss, which may play an important role in limb development evolution across tetrapods, providing new insights into how species adapt morphologically over time.

The Mary Rose, for many years the flagship of the Tudor king, Henry VIII, sank during the battle of the Solent on the 19th July 1545. 437 years later, the remains of the hull and associated contents were recovered following a four-year excavation, all dated to a precise point in history. The assemblage is a valuable resource, as the environment preserved over 19,000 objects and the remains of a minimum of 179 crew members.
