Colossal Biosciences successfully hatched 26 healthy chicks from 3D-printed artificial eggshells, advancing their de-extinction goals. The silicone-based membrane lattice allows oxygen passage while protecting embryos, crucial for species like the South Island giant moa that are too large for existing surrogates. Their system could potentially apply to conservation efforts despite ongoing criticism.

The European Space Agency and Chinese Academy of Sciences jointly launched the Smile spacecraft to study Earth's magnetic shield through X-ray observations and ultraviolet imaging of northern lights. Equipped with specialized cameras and analyzers, the mission launched from French Guiana on May 19 and will begin collecting data in July, offering unprecedented views of Earth's protective magnetic field.

Scientists reanalyzed 14 years of Hubble data and reduced confidence in water vapor plumes on Jupiter's moon Europa from 99.9% to less than 90%. Meanwhile, SpaceX's Starship V3 completed its first test flight, demonstrating continued progress in the company's ambitious space exploration goals.
