Research ArticlePLANETARY SCIENCEScience Advances1 Jan 2025Vol 11, Issue 1INTRODUCTIONOrbital and in situ observation magnetic data indicate that the present-day Moon does not have a global magnetic field; nonetheless, large-scale crustal magnetization with maximum local magnetic anomalies at the lunar surface reaching hundreds of nanoteslas suggests the presence of a strong magnetic field in the past (1, 2) (Fig. 1).

AbstractUnravelling the volcanic history of the enigmatic lunar farside is essential for understanding the hemispheric dichotomy of the Moon1-3. Cratering chronology established for the lunar nearside has been used to suggest long-lived volcanism on the farside of the Moon3,4, but without sample verification. Here we report two newly recognized episodes of basaltic volcanism with Pb-Pb dating for basalt fragments returned by the Chang’e-6 mission.

Laser ablation has been used in different surgical procedures to perform precise treatments. Compared with previous free-beam laser delivery systems, flexible-optical-fiber-based systems can deliver laser energy to a curved space, avoiding the requirement of a straight working path to the target. However, the fiber tip maintains direct contact with the tissue to prevent laser divergence, resulting in fiber damage, uneven ablation, and tissue carbonization.
