WiFi Drones Stand Up Network During Emergencies


by Michael Keller

Some of the first responders to enter future disaster zones might be tiny drones equipped with transmitters designed to reestablish WiFi and cellphone communications. 

University of North Texas electrical engineers have unveiled prototypes of the multirotor aerial vehicles that they are designing to fly in pairs after the network goes down. One drone would land in the area—perhaps on a rooftop—and the second would be placed in line of sight of the first up to almost two miles away. 

See the video and read more below.

Spiders are important predators. By one estimate, the spiders on one acre of woodland alone consume more than 80 pounds (36 kg) of insects a year. (Those insect populations would explode without the predators.)

Spiders employ an amazing array of techniques to capture prey.

They play tricks:

Some pirate spiders of the family Mimetidae fool their prey: other spiders. They vibrate the spiders’ webs the same way a struggling insect might. Then, when the host spiders come close, the pirates grab them.

They spit: 

Spiders of the genus Scytodes catch prey by ejecting a glue from their chelicerae (spider mouthparts that end in fangs and inject venom into prey). Once it hits, the gooey substance shrinks, trapping the prey in place.

They use a home field advantage:

Lynx spiders of the family Oxyopidae hunt on plants. They are agile, jumping from stem to stem, and have better vision than many other spiders.

Whip spiders (Amblypygi)

Amblypygi form a separate order of arachnids alongside the spiders, scorpions and others. They are harmless to humans. Amblypygids possess no silk glands or venomous fangs. They rarely bite if threatened, but can grab fingers with pedipalps, resulting in thorn-like puncture injury. They are found in tropical and subtropical regions worldwide. Some species are subterranean; all are nocturnal. Amblypygids range from 3 to 23.6 inches (7.6 to 60 cm) in size according to legspan. The first pair of legs act as sensory organs and are not used for walking. The sensory legs are very thin and elongate, have numerous sensory receptors, and can extend several times the length of body. Typically, the animal holds one of these legs out in front of it as it moves, and uses the other to probe the terrain to the side. Amblypygids will consume any appropriately sized prey. Most of their diet likely consists of insects.

Candy crab (Hoplophrys oatesi)

The candy crab is a very colourful crab that grows from 1.5 to 2 cm. It lives on various species of soft coral in the Dendronephthya genus. It camouflages itself by mimicing the colours of the polyps among which it hides. It adds further camouflage by attaching polyps to its carapace. Colours vary depending on the colour of the coral, and may be white, pink, yellow or red. This crab is widespread in the Indo-Pacific and it feeds on plankton. photo credits: digimuse, Brian Maye, divemecressi
