The update mainly quantifies the receiver’s operating conditions, newly reporting 520-nanometer input and temperatures around 80–90°C. The core result and its experimental limitations remain unchanged.

The story is largely a reframing rather than a substantive new development: the same laser-powered drone receiver remains laboratory-only, but the current version trims institutional detail and emphasizes practical barriers more directly. The scope also broadens slightly to note additional prospective applications, including military use.
