Lego-like 3D-printed beams offer lightweight alternative to concrete

Reinforced concrete beams serve as important structural elements for buildings and bridges, but they are long and heavy and therefore require large machinery to both transport and install. Researchers at Spain’s Polytechnic University of Valencia have … Continue reading Lego-like 3D-printed beams offer lightweight alternative to concrete

Smart speaker uses AI to detect irregular heart rhythms in the room

Scientists at the University of Washington (UW) have leveraged modern machine learning technology to produce a prototype smart speaker that can monitor a person’s heart, without the need for them to physical touch it. The contactless method of tracking… Continue reading Smart speaker uses AI to detect irregular heart rhythms in the room

Blue Origin’s spinning New Shepard capsule to simulate lunar gravity

For NASA and anyone else developing technologies for use on the Moon, opportunities to test them out beforehand in lunar-like conditions are rather limited.
