New AR display tech boosts real‑world visibility while keeping virtual objects lifelike

Optical see-through augmented reality (AR) glasses are designed to overlay digital information onto the real world, but improving the realism of virtual objects often comes at a cost. Existing occlusion technologies physically ...

3D-printed bridge points the way to greener construction

Concrete is the most widely used building material on Earth, and producing it is one of the largest single sources of carbon emissions. One promising way to reduce its environmental footprint is to 3D-print concrete, laying ...

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 ...

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 ...

A metamaterial that bridges air and water

Have you ever tried yelling underwater? Not only is it difficult to make the noise, but it is rarely audible to those outside of the water. Sound travels differently in mediums of different densities, and that causes a high ...

Artificial tendons give muscle-powered robots a boost

Our muscles are nature's actuators. The sinewy tissue is what generates the forces that make our bodies move. In recent years, engineers have used real muscle tissue to actuate "biohybrid robots" made from both living tissue ...

Climate-friendly metals can come from deep-sea ores

The demand for metals will increase significantly in the coming years, primarily because the climate-friendly transformation of the economy is only possible through the electrification of industrial processes, transport and ...
