Moths aren’t known as beasts of burden, but a new super lightweight sensor they can carry on their backs might change that.

A team of researchers at the University of Washington (UW) developed a sensor that weighs 98 milligrams (one tenth the weight of a jellybean) and can survive a six-story fall. The sensors are designed to last three years and collect and wirelessly transmit environmental data like temperature or humidity. 

The tough little sensors can be delivered by dainty drones or carried on the backs of insects. A video released by UW shows both of these options in action. The hawkmoth shown in the footage is a large species of moth and the sensor fits easily on its back.

Turkey is developing an increasing variety of lethal armed drones that range from large high-flying bomb-laden ones to very small, low-flying ones that can form deadly swarms.

In recent years, Turkey has developed an impressive local drone industry from the ground up. Armed Turkish-built Bayraktar TB2 and Anka-S drones have already proven themselves in combat in operations in Syria, Iraq, and even as far afield as Libya.

Ankara is presently building a variety of bigger and smaller drones that will fulfill a multitude of different roles for the Turkish military.

The Australian National University (ANU) and Optus announced on Thursday the pair would attempt to develop a national system to detect and extinguish fires using a mixture of satellites, drones, and robotics.

The first step of the program, which is due to run until 2024, will be to create an “autonomous ground-based and aerial fire detection system”.

It will begin with the trial of long-range infra-red sensor cameras placed on towers in fire-prone areas in the ACT, which will allow the ACT Rural Fire Service (RFS) to monitor and identify bushfires.

The long-term goal, though, is to put out fires using drones.

“We hope to develop a system that can locate a fire within the first few minutes of ignition and extinguish it soon afterwards,” ANU vice-chancellor Professor Brian Schmidt
