Army researchers are working with the University of Illinois Chicago on unmanned technology for recharging drone swarms.
The university has been awarded a four-year, $8 million cooperative agreement “to develop foundational science in two critical propulsion and power technology areas for powering future families of unmanned aircraft systems,” according to a statement released by the Army Research Laboratory.
“This collaborative program will help small battery-powered drones autonomously return from military missions to unmanned ground vehicles for recharging,” the Army added. “The university is developing algorithms to enable route planning for multiple teams of small unmanned air and ground vehicles.”
ARMY DEVELOPING DRONES THAT CAN CHANGE SHAPE MID-FLIGHT
The military is looking to make the process of recharging vast drone swarms as efficiently as possible by using fast, recharging batteries and wireless power transfer technologies. This, researchers say, will let multiple drones to hover over an unmanned ground vehicle and recharge
When immune system T cells find and recognise a target, they release chemicals to attract more T cells which then swarm to help subdue the threat, shows a new study published today in eLife.

The discovery of this swarming behaviour, and the chemical attractants that immune cells use to direct swarms towards tumours, could one day help scientists develop new cancer therapies that boost the immune system. This is particularly important for solid tumours, which so far have been less responsive to current immunotherapies than cancers affecting blood cells.
“Scientists have previously thought that cancer-killing T cells identified tumours by randomly searching for them or by following the chemical trails laid by other intermediary immune cells,” says lead author Jorge Luis Galeano Niño, a PhD graduate at UNSW Sydney. “We wanted to investigate this further to see if it’s true, or whether T cells locate tumours via another mechanism.”

A swarm of more than 400 earthquakes has hit California in the area between the San Andreas fault and the Imperial fault, with further seismic activity and potentially larger earthquakes set to follow over the next week.
The biggest earthquake that has been recorded in the swarm so far was a magnitude 4.9, which hit at 5.31 p.m. local time on September 30, but bigger quakes are a possibility.
“In a typical week, there is approximately a three in 10,000 chance of a magnitude 7+ earthquake in the vicinity of this swarm,’ the U.S. Geological Survey (USGS) said in a statement. “During this earthquake swarm, the probability of larger earthquakes in this region is significantly greater than usual. Currently, the swarm is rapidly evolving, and we expect to update this forecast with more specific probability information as we collect more data.”
The most likely scenario is that the rate of

SAN FRANCISCO – Swarm Technologies, a Silicon Valley startup seeking to connect sensors in a low-cost, global internet-of-things (IoT) network, announced prices for its satellite communications products Sept. 29, including data services starting at $5 per device per month..
Swarm launched its first 12 operational Spacebee satellites in early September aboard an Arianespace Vega rocket. The Mountain View, California, company plans to complete its constellation of 150 hockey-puck-size satellites before the end of 2021, Sara Spangelo, Swarm co-founder and CEO, said in a Sept. 21 blog post.
Swarm Tile, the company’s satellite modem, carries a $119 price tag. Customers are encouraged to embed Swarm Tile, which is built around a single printed circuit board, into devices.
“Now, every person and IoT machine can have affordable access to two-way data services from any point on Earth at all times,” Spangelo said in a Sept. 29 statement. “Swarm’s global network enables customers
