Biology of ventilationAir moves from our lungs into the bloodstream through tiny, air-filled sacs called alveoli. Open circuit ventilatorsThis is a very simple version of a ventilator where waste gas is expelled from the system without recycling. Closed circuit ventilatorsThis... Continue Reading →
Northwestern University engineers have developed the smallest-ever remote-controlled walking robot — and it comes in the form of a tiny, adorable peekytoe crab. Just a half-millimeter wide, the tiny crabs can bend, twist, crawl, walk, turn and even jump. The... Continue Reading →
Researchers have developed electronic artificial skin that reacts to pain just like real skin, opening the way to better prosthetics, smarter robotics and non-invasive alternatives to skin grafts. The prototype device developed by a team at RMIT University in Melbourne,... Continue Reading →
MIT engineers have designed a "brain-on-a-chip," smaller than a piece of confetti, that is made from tens of thousands of artificial brain synapses known as memristors -- silicon-based components that mimic the information-transmitting synapses in the human brain. The researchers... Continue Reading →
This summer, NASA plans to launch its next Mars rover, Perseverance, which will carry with it the first aircraft to ever fly on another planet, the Mars Helicopter. As the first of its kind, the Mars Helicopter will carry no... Continue Reading →
When electronics need their own power sources, there are two basic options: batteries and harvesters. Batteries store energy internally, but are therefore heavy and have a limited supply. Harvesters, such as solar panels, collect energy from their environments. This gets... Continue Reading →
One of the ways we experience the world around us is through our skin. From sensing temperature and pressure to pleasure or pain, the many nerve endings in our skin tell us a great deal. Our skin can also tell... Continue Reading →
The X-59 Quiet SuperSonic Technology, or QueSST, wing assembly is lifted by a crane and moved to another area of the manufacturing floor in preparation for wing skin installation. The aircraft is under construction at Lockheed Martin in Palmdale, California, and will... Continue Reading →
Scientists at the University of Massachusetts Amherst have developed a device that uses a natural protein to create electricity from moisture in the air, a new technology they say could have significant implications for the future of renewable energy, climate... Continue Reading →
