Border Drone Downing Spurs Demands for Interagency Oversight

Democratic lawmakers condemned the Trump administration after the military used a high-powered laser to down what it said was a threatening drone near the US–Mexico border, later identified as a CBP drone, highlighting interagency coordination gaps. The incident follows a prior episode where a CBP laser hit a party balloon, and ongoing airspace restrictions near Fort Hancock, with Republicans and Democrats urging independent review and stricter coordination between the FAA, the Pentagon, and CBP. The FAA seeks a safety review of anti-drone lasers and has paused testing until it’s completed, while agency disagreements about pre-approval for laser use persist.

Laser flips magnetism in twisted 2D material, enabling light-defined circuits

Researchers demonstrated optical, non-thermal control of magnetism in a twisted bilayer MoTe2; a laser pulse reversibly flips the ferromagnetic polarity, with switching dynamics tied to whether electrons reside in a topological insulating or metallic state. This links topology and magnetism in a single platform and suggests future possibilities for light-written topological circuits and tiny interferometers on chips.

DC Jury Clears Man in Laser-Targeting of Marine One Amid Trump-Era Tension

A Washington, DC jury acquitted Jacob Winkler of a felony charge for aiming a laser at Marine One as a Trump-era helicopter flight, delivering the verdict in about 35 minutes and marking a setback for US Attorney Jeanine Pirro’s office, which had pursued harsh penalties for perceived threats to the president. Defenders argued the case wasted resources policing poverty, noting Winkler was homeless with a cat toy keychain at the time of his arrest.
