New spinning drone hides in plain sight: 'Phantom Twist' harnesses motion blur to nearly vanish in flight

By exploiting the quirks of human vision, Northwestern University engineers have designed a drone that nearly disappears before the eyes. For years, researchers have tried to design invisible drones and robots using camouflage, ...

Engineers develop robot that judges its surroundings and walks, runs, and jumps like an animal

An era in which robots decide "how to walk" on their own has arrived. A four-legged robot has been developed that, much like a person or an animal, autonomously chooses the appropriate gait strategy for its surroundings—changing ...

Researchers mimicked bird bones to create lightweight, high-performance structures

Using bird bone structure as inspiration, Xin Ning and Sepideh Ebad Sichani, Ph.D. '26, have created a new class of aircraft wing structures—unbound by traditional designs of ribs, spars and stiffeners. The researchers are ...

Lower printing temperatures cut defects in aluminum 3D-printed parts, study finds

Scientists at The University of Manchester have uncovered how subtle changes in temperature during a promising metal 3D printing process can significantly affect the quality of aluminum components.

Smaller homes could cut Europe's CO₂ building emissions

Buildings are responsible for around 40% of CO2 emissions in the European Union. This means the building sector has a central role to play in achieving the EU's climate targets by 2050. An EU research project involving Graz ...

Sand could be key to safer, stronger structures

Engineers have been working for centuries to protect buildings, bridges and other structures from damage caused by severe weather and natural hazards, but one of the best methods may begin with sand, according to a newly ...

Holographic printer produces 3D shapes in one shot

University of Utah researchers have demonstrated a new method of 3D printing that avoids the leaky seams that come with the layer-by-layer process. Using a nanoscale "mask" that diffracts laser light into a holographic pattern ...

Supercharging the grid: How to free up 20% more power

Implementing effective monitoring measures could yield much more energy from the cable network—all without digging a single new trench. Just a dream scenario? No, it is entirely possible, say researchers.

Dust-prone desert of the Southwest may be ideal for solar energy

Solar energy developers eyeing parts of southern New Mexico may have less to worry about than expected when it comes to dust. A new study led by University of Texas at El Paso researchers concludes that photovoltaic panels ...

Engineering

Carbon ratios in concrete can improve carbon accounting

For the first time, researchers, including those from the University of Tokyo, have found out how to determine how much carbon dioxide (CO2) from either natural or anthropogenic sources can be absorbed by special concrete ...

Why your building is often too hot, or cold—and the simple fix

In many cases, heating can be significantly improved simply by adjusting existing controls to account for sunlight, ventilation and how many people are inside, according to researchers at KTH Royal Institute of Technology ...

Accelerating the production of higher-performance batteries

Demand for batteries for electric vehicles and energy storage systems is growing exponentially. Fraunhofer ITWM relies on digital simulation tools and innovative measurement systems to ensure that manufacturing processes ...

Efficiently cooling satellite components in space

Space is a vacuum. Heat therefore cannot be transferred to the surroundings by thermal conduction. This poses a problem for any type of space-capable electronics, which can quickly overheat under these conditions. The only ...

NASA's X-59 prepares for first supersonic flight

NASA's X-59 quiet supersonic research aircraft is preparing for some of its most significant flights yet. The X-plane is about to begin a new block of test flights that will include its first time flying faster than the speed ...

Underground acoustic signals reveal hidden tunnels

For decades, engineers have searched for underground tunnels by sending signals from the surface downward—an approach that can miss what lies below. By reversing that approach, researchers at the Department of Energy's (DOE) ...
