New foldable drone flies through narrow holes in rescue missions

December 12th, 2018
A research team has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Scientists exchanged quantum information on daylight in a free-space quantum key distribution

December 7th, 2018
Scientists have reported a successful free-space quantum key distribution (QKD) in daylight with the self-developed polarization encoding chip for the first time. QKD is one of the most promising secure communication technologies, which encodes information into a single-photon, the smallest measurable unit of light. By using the quantum mechanical properties of the single-photon, quantum cryptography guarantees secure information exchange between the distant parties.

Team converts wet biological waste to diesel-compatible fuel

December 4th, 2018
In a step toward producing renewable engine fuels that are compatible with existing diesel fuel infrastructure, researchers report they can convert wet biowaste, such as swine manure and food scraps, into a fuel that can be blended with diesel and that shares diesel's combustion efficiency and emissions profile.

Putting hybrid-electric aircraft performance to the test

November 27th, 2018
Although hybrid-electric cars are becoming commonplace, similar technology applied to airplanes comes with significantly different challenges. Aerospace engineers are addressing some of them toward the development of a more sustainable alternative to fossil fuels to power airplanes.

Drones offer ability to find, ID and count marine megafauna

November 26th, 2018
New research demonstrates that consumer-grade drones are effective tools for monitoring marine species across multiple sites in the wild. The work shows that the technology can be a valuable platform for scientists and conservationists interested in studying populations of sharks, rays, sea turtles and other marine megafauna.

Engineers fly first-ever plane with no moving parts

November 23rd, 2018
Engineers have built and flown the first-ever plane with no moving parts. Instead of propellers or turbines, the light aircraft is powered by an 'ionic wind' -- a silent but mighty flow of ions that is produced aboard the plane, and that generates enough thrust to propel the plane over a sustained, steady flight.

Could an anti-global warming atmospheric spraying program really work?

November 23rd, 2018
A program to reduce Earth's heat capture by injecting aerosols into the atmosphere from high-altitude aircraft is possible, but unreasonably costly with current technology, and would be unlikely to remain secret. Those are the key findings of new research which looked at the capabilities and costs of various methods of delivering sulphates into the lower stratosphere, known as stratospheric aerosol injection (SAI).

New scheduling system could help reduce flight delays

November 13th, 2018
Scheduling and coordinating air traffic can be difficult, but taking the airlines' and passengers' delay costs into account can actually save airlines money and result in fewer delays, according to a new study.

Fleets of drones could aid searches for lost hikers

November 2nd, 2018
Researchers describe an autonomous system for a fleet of drones to collaboratively search under dense forest canopies. The drones use only onboard computation and wireless communication -- no GPS required.

Bose-Einstein condensate generated in space for the first time
