For the 2nd time, Northrop Grumman catches a satellite in Earth orbit

Northrop Grumman said last week that its Mission Extension Vehicle 2 – a robot spacecraft designed to help prolong the life of satellites in space – successfully docked to a commercial communications satellite. “We are now the only provider of life extension services for satellites,” a company spokesperson said.

‘Like a Beautifully-tuned Instrument’: 2000 Microphones Unlock the Mystery of Why Hummingbirds Hum

The hummingbird is named after its pleasant humming sound when it hovers in front of flowers to feed. But only now has it become clear how the wing generates the hummingbird’s namesake sound when it is beating rapidly at 40 beats per second. Researchers from Eindhoven University of Technology, Stanford University, and Sorama meticulously observed […]

Controlled by light alone, new smart materials twist, bend and move

(Tufts University) Engineers created light-activated materials that execute precise movements and form complex shapes without the need for wires, motors or other energy sources. The research could lead to smart light-driven systems such as high-efficiency solar cells that automatically follow the sun’s direction.

NASA selects 16 futuristic space technology concepts

NASA has selected 16 cool new futuristic space technology concepts for further study. Four of them are from NASA’s own Jet Propulsion Laboratory (JPL), including a railway system on the moon to move cargo.

Microbiome boost may help corals resist bleaching

(King Abdullah University of Science & Technology (KAUST)) Providing corals with cocktails of natural probiotics could enhance their tolerance to stress and reduce mortality in coral bleaching events.

Using genes to improve greenhouse gases conversion

(University of Queensland) Greenhouse gas waste from factories could be turned into environmentally-friendly chemicals and fuels under an international project seeking to better understand the gene function of bacteria.

What impact will robots and autonomous systems have on urban ecosystems?

(University of Seville) Unmanned aerial vehicles (drones), autonomous cars, robots that can repair urban infrastructure and wireless sensor networks used for monitoring, etc. are just some of the devices that will spring up all over our cities in a few years. They have a wide range of potential applications, such as autonomous transport, waste collection, infrastructure maintenance and repair, surveillance and precision agriculture, among others. However, we must also consider the impact these technologies will have on urban biodiversity and its ecosystems in the future.
