Briefs: Medical
A team has developed a new cable system for heart pumps that doesn’t cause infections. This is particularly important given that wireless methods of transmitting power remain unavailable to patients in the foreseeable future.
Briefs: Robotics, Automation & Control
A team at ETH Zurich has developed an ultrasonically actuated glass needle that can be attached to a robotic arm. This lets them pump and mix minuscule amounts of liquid and trap particles.

One of the strategies to combat the mounds of waste found in oceans — especially around coral reefs — is to employ robots to master the cleanup. However, existing underwater robots are mostly bulky with rigid bodies, unable to explore and sample in complex and unstructured environments, and are noisy due to electrical motors or hydraulic pumps.

Hydraulic-Based Spherical Robot
Current spherical robots rely upon rotating mechanical weights inside the sphere to change the center of gravity of the sphere, causing the robot to roll. The use of rotating mechanical weights is not optimal due to the reliance upon moving parts, which can present burdensome maintenance issues. It would be...
