New Dental Imaging Method Uses Squid Ink to Fish for Gum Disease

Squid ink might be a great ingredient to make black pasta, but it could also one day make getting checked for gum disease at the dentist less tedious and even painless. By combining squid ink with light and ultrasound, a team led by engineers at the University of California San Diego has developed a new dental imaging method to examine a patient's gums that is non-invasive, more comprehensive, and more accurate than the state of the art.

Non-Invasive Imaging Predicts Cancer Malignancy

A new study by Osaka University scientists shows that non-labeling multiphoton microscopy (NL-MPM) can be used for quantitative imaging of cancer that is safe and requires no resection, fixation, or staining of tissues. It’s expected to simplify and reduce the time of cancer diagnosis.

Soft Robotic Gripper Manipulates Objects Without Training

An engineering team at the University of California San Diego has designed and built a gripper that can pick up and manipulate objects without needing to see them and without being trained. The gripper is unique because it brings together three different capabilities. It can twist objects, it can sense objects, and it can build models of the objects it’s manipulating. This allows the gripper to operate in low light and low visibility conditions, for example.

Vacuum System Powers Modular Soft Robot

Researchers at the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have created the first functional robot powered entirely by vacuum. It is made up of soft building blocks that move by having air sucked out of them. The robot can be reconfigured to perform different tasks, like climbing vertical walls and grabbing objects.
