NASA Helps Return Giant Tortoises to Galápagos After 150 Years

NASA satellite technology helped guide the return of 158 giant tortoises to Floreana Island in the Galápagos, where the species vanished 150 years ago. Scientists used data from Landsat and other missions to map ideal release spots for the animals, which once shaped the island’s ecosystem. The rewilding project could serve as a model for future restoration efforts worldwide.

Chinese scientists put quantum chaos in slow motion for first time

Chinese Academy of Sciences researchers have directly observed and manipulated prethermalisation, a stable phase before quantum systems descend into chaos. Using the 78-qubit Chuang-tzu 2.0 processor, the team led by Fan Heng can lengthen or shorten this information-preserving window. The breakthrough offers new possibilities for quantum error correction and extending the lifetime of quantum states, bringing practical quantum computing closer to reality.

Germany’s Max Planck Institute Finds Giant Virus Hijacks Cell Machinery

Scientists from Germany’s Max Planck Institute have discovered that a giant virus called mimivirus hijacks host cells’ protein-making machinery to multiply up to 100,000 times faster. The virus makes a complex of three proteins that takes over ribosomes, forcing cells to produce viral proteins instead of their own. Published in Cell on February 17, this is the first experimental evidence that viruses can co-opt a system typically associated with cellular life.
