Hurricane researchers sent a marine drone into Hurricane Fiona, where it captured intense footage of the tropical storm. The research drone will help scientists better understand how tropical storms rapidly intensify.

Recently, the collaboration between the U.S. National Oceanic and Atmospheric Administration (NOAA) and Saildrone, a company that develops sailing drones, did exactly that. They sent a robot into Hurricane Fiona, the tropical storm that has deluged Puerto Rico and is now headed towards Canada’s east coast, Mashable reported.
Russia’s war on Ukraine has turned a lot of assumptions about the fundamental nature and trajectory of how wars are fought, on its head.
For one thing, Ukraine’s strong defense has upended conventional wisdom about big powers being able to violate at will the sovereignty of little powers.
The technology, which has been tested in the lab, could ultimately be used for manufacturing and building in difficult-to-access or dangerous locations such as tall buildings or help with post-disaster relief construction, say the researchers.
3D printing is gaining momentum in the construction industry. Both on-site and in the factory, static and mobile robots print materials for use in construction projects, such as steel and concrete structures.

Florida’s “silent” flying dish-rack, powered by ionic propulsion, is on track for commercial rollout in 2024, according to Undefined Technologies, which has released new outdoor flight test video. We remain curious, but unconvinced it’ll be viable.
The “Silent Ventus” drone doesn’t use propellers to fly. Instead, its entire broad structure creates two stacked grids of electrodes, designed to create high-voltage electric fields that can ionize the oxygen and nitrogen molecules in the air, freeing electrons to give them a positive charge, and then propelling these downward to create an “ionic wind” that can produce thrust.

The drones will help the construction industry in hard-to-reach and dangerous places.
Consider the drone bees. These bees, which probably gave their name to today’s drones, are also may have inspired by their physical features. Let’s learn how.

The California-based Matternet has been testing its Model M2 drone over the past four years in the US as part of the FAA’s Unmanned Aircraft System (UAS) program. Matternet says getting the green light from the FAA could help streamline the process of “implementing new networks and getting approvals.”
Matternet partnered with UPS in 2019 to deliver medical supplies in North Carolina, and later started delivering prescriptions in Florida. Matternet also expanded its footprint to Switzerland, where it teamed up with the Swiss Post to deliver lab samples and blood tests. The program was briefly suspended in 2019 after its drones suffered two crashes in the country, but Matternet has since announced that it’s taking over the Swiss Post’s drone delivery program starting in 2023.
In a statement, the FAA says Matternet’s Model M2 drone “meets all federal regulations for safe, reliable and controllable operations and provides a level of safety equivalent to existing airworthiness standards applicable to other categories of aircraft.” The four-rotor drone’s been approved to carry four-pound payloads and fly at an altitude of 400 feet or lower with a maximum speed of 45mph.
Iran’s recent seizure of unmanned US Navy boats shined a light on a pioneering Pentagon program to develop networks of air, surface and underwater drones for patrolling large regions, meshing their surveillance with artificial intelligence.
The year-old program operates numerous unmanned surface vessels, or USVs, in the waters around the Arabian peninsula, gathering data and images to be beamed back to collection centers in the Gulf.
The program operated without incident until Iranian forces tried to grab three seven-meter Saildrone Explorer USVs in two incidents, on August 29–30 and September 1.
160,000 square kilometers of the Ukrainian territory of land may be “contaminated” by landmines.
New technology to detect lethal explosives designed to maim and kill has been tested by researchers from the Demining Research Community.
