Making flying actually sustainable

CO2 -neutral synthetic fuels are technically feasible today and the best promise for decarbonizing aviation. The right policy instruments could turn promise into reality, writes Anthony Patt.

To improve drones, researchers study flying insects

The unmanned aircraft known as drones, used by hobbyists, researchers and industry to take aerial images and perform other tasks, are growing ever more popular—and smaller. But that miniaturization, which has produced drones ...

A new manufacturing process for aluminum alloys

An advanced manufacturing process to produce nano structured rods and tubes directly from high-performance aluminum alloy powder—in a single step—was recently demonstrated by researchers from the Pacific Northwest National ...

A device emerges from the fusion of IGZO and ferroelectric-HfO2

As a part of JST PRESTO program, Associate professor Masaharu Kobayashi, Institute of Industrial Science, the University of Tokyo, has developed a ferroelectric FET (FeFET) with ferroelectric-HfO2 and ultrathin IGZO channel. ...

Drones for early detection of forest fires

The UC3M's researchers coordinating the scientific part of the project, Fernando García y Abdulla al-Kaff, from the Department of Systems Engineering and Automation, have developed the complete automatic flight system, as ...

Making the 'human-body internet' more effective

Wireless technologies such as Wi-Fi and Bluetooth have made remote connectivity easier, and as electronics become smaller and faster, the adoption of "wearables" has increased. From smart watches to implantables, such devices ...

Soon, air pollution could be measured on every street corner

Air pollution is responsible for 550,000 premature deaths a year in Europe and 7 million worldwide, according to the WHO. Measuring it can be a challenge, however, as the equipment tends to be large and expensive. But soon, ...

Injection-molding wood powder for sustainable fabrication

Biomass materials such as wood are environmentally-friendly alternatives to fossil resources. As an example, wood is typically non-toxic and carbon neutral. Furthermore, wood can be produced in a sustainable manner by appropriate ...

EU publishes Europe-wide rules on drone operation

The European Union has published EU-wide rules on drones to provide a clear framework for what is and isn't allowed, improve safety and make it easier for drone users to operate their craft in another European country.

Clarifying the economic value of adjusting power consumption

Since the output of renewable energy such as photovoltaic generation tends to fluctuate, the power system can be viewed as a large-scale complex system with uncertainty. To stabilize the balance of supply and demand of electricity, ...

Legislators: Boeing wanted to wait 3 years to fix Max flaw

Two key lawmakers said Friday that Boeing planned to delay fixing a nonworking safety alert on its 737 Max aircraft for three years and sped up the process only after the first of two deadly crashes involving Max planes last ...
