The impact universe-a framework for prioritizing the public interest in the Internet of Things.

The connected technologies of the Internet of Things (IoT) power the world we live in. IoT systems and devices are critical infrastructure-they provide a platform for social interaction, fuel the marketplace, enable the government, and control the home. Their increasing ubiquity and decision-making capabilities have profound implications for society.

Laboratory and field insights into the dynamics and behavior of Argentine ants, Linepithema humile, feeding from hydrogels.

Background: Hydrogels that have absorbed a liquid containing a toxicant are a novel form of bait-delivery for ant control. Here, we study the abilities of Argentine ant (Linepithema humile) workers to imbibe liquid from hydrogels. We quantified feeding behavior with: (i) hydrogels containing different sucrose concentrations (20, 30, 40 and 50% w/w); (ii) hydrogels versus liquid droplets; and (iii) hydrogel age (air exposure time).
