A new preprint says SETI may be searching for the wrong type of optical signal.
The authors argue practical civilizations might prefer longer, cheaper laser pulses over ultra-short bursts.
They also suggest detectable beacons may be placed far from a home star to reduce interference.

University of Virginia researchers developed a continuous-wave infrared laser method for backsheet removal in end-of-life silicon solar modules.
The process heats the silicon-EVA interface through the front glass and enables clean mechanical delamination.
Researchers say the method is non-chemical and could offer a lower-energy, lower-cost alternative to conventional recycling routes.

Two new experiments support the smaller proton size first flagged in 2010.
Both studies used hydrogen atoms and laser-controlled electron transitions.
The measurements point to a proton radius of about 0.84 femtometres.
A firmer proton radius could improve future precision tests and searches for new particles.
