Why shaving dulls even the sharpest of razors

Human hair is 50 times softer than steel, yet it can chip away a razor’s edge, a new study shows.

Recent work from MIT CSAIL addresses how computers divide objects into sets of smaller elements, a procedure known as “meshing.” Zhang et al. produced a range of detailed 2D images without depending on unreliable methods that try to trace out features like curves and edges ahead of time.

Better simulation meshes well for design software (and more)

New work on 2D and 3D meshing aims to address challenges with some of today’s state-of-the-art methods.

Using a new calcium indicator that accumulates in the cell bodies of neurons (boxes at right), MIT neuroscientists are able to more accurately image neuron activity. Traditional calcium indicators (boxes at left) can generate crosstalk that blurs the images.

A focused approach to imaging neural activity in the brain

New molecule for imaging calcium in neurons reduces crosstalk from neighboring neurons.

A new technology called ELAST transforms tissues, such as this slab of human brain, to make them reversibly stretchable or compressible, as well as much more durable. This allows them to be repeatedly stretched out or squished down thin for much faster infusion of labeling probes, which labs use to highlight cells or molecules under the microscope.

Making tissue stretchable, compressible, and nearly indestructible

Chemical process called ELAST allows labeling probes to infuse more quickly, and makes samples tough enough for repeated handling.

In this lidar map, AI algorithms have identified roads (red). By pairing this map with OpenStreetMaps, users can plan routes around roads that are deemed impassable and can do so at the scale of an entire sortie, which here covers about 400 square miles.

With lidar and artificial intelligence, road status clears up after a disaster

Automated tools can help emergency managers make decisions, plan routes, and quantify road damage at city scales.

A new ultrasound technique uses lasers to produce images beneath the skin, without making contact with the skin as conventional ultrasound probes do. The new laser ultrasound technique was used to produce an image (left) of a human forearm (above), which was also imaged using conventional ultrasound (right).

Researchers produce first laser ultrasound images of humans

Technique may help remotely image and assess health of infants, burn victims, and accident survivors in hard-to-reach places.
