Phys.org: Posts, tweets spread widely as the Harvey missing are sought. “Photos with pleas for help in finding the missing from Hurricane Harvey are being posted, cut-and-pasted and retweeted by thousands of people as desperate family members seek loved ones who they fear might be dead, but may only have a dead phone. No official number of the unaccounted-for had been released Tuesday night amid the vast uncertainty of the storm’s fourth day, with authorities saying the 18 deaths confirmed so far could surge in the days to come.”
