New glass-ceramic emits light when under mechanical stress

WASHINGTON — Researchers have created a new glass-ceramic that emits light in response to mechanical stress, a property known as mechanoluminescence. With further development, the new material could be used to create a light source that is switched on by mechanical stress. This could be useful for monitoring stress in artificial joints in the body … Read more

What the mechanical forces behind protein folding can tell us about metastatic cancer – BIOENGINEER.ORG

Tallinn is a protein that controls cellular attachment and movement, but its malfunctioning also allows cancer cells to spread. DCL1 is a tumor-suppressing protein. But scientists don’t fully understand how either protein works – or what happens when they don’t work the way they should. Tallinn is a protein that controls cellular attachment and movement, … Read more

Scripps Research scientists identify sensor underlying mechanical itch – BIOENGINEER.ORG

LA JOLLA, CA—Scientists at Scripps Research have identified a protein in sensory nerves that works as a key detector of itch — specifically the “mechanical” itch stimulus of crawling insects, wool fibers, or other irritating objects that touch the skin. LA JOLLA, CA—Scientists at Scripps Research have identified a protein in sensory nerves that works … Read more

Researchers Just Found That Kidneys Act on Blood Differently Than We Thought Before

By this time tomorrow, every drop of blood in your body will have passed through your kidneys dozens of times. With each pass, water saturated with waste is removed to form urine, and freshly cleaned blood then returns back into circulation. We might imagine this vital task as a kind of force-fed filtration driven by … Read more

Scientists Just Measured a Mechanical Quantum System Without Destroying It

There’s a key aspect of quantum computing you may not have thought about before. Called ‘quantum non- demolition measurements’, they refer to observing certain quantum states without destroying them in the process. If we want to put together a functioning quantum computer, not having it break down every second while calculations are made would obviously … Read more

How Properties of Mechanical Quantum Systems Can Be Measured Without Destroying the Quantum State

Going gentle on mechanical quantum systems – BIOENGINEER.ORG

When thinking about quantum mechanical systems, single photons and well- isolated ions and atoms may spring to mind, or electrons spreading through a crystal. More exotic in the context of quantum mechanics are genuinely mechanical quantum systems; that is, massive objects in which mechanical motion such as vibration is quantized. In a series of seminal … Read more

MIT class journeys to fascinating places where mechanical engineering affects biology | MIT News

Even for a second-year PhD student researching the mechanics of living cells, the influence of physical forces within the world of living things is a source of wonder. “I did undergrad in engineering mechanics, and ever since I started to look at cells, the more I’ve found it fascinating to look at them as delicate‘ … Read more
