New terahertz imaging approach could speed up skin cancer detection
Researchers have developed a new terahertz imaging approach that, for the first time, can acquire micron-scale resolution images while retaining computational approaches designed to speed up image acquisition. This combination could allow terahertz imaging to be useful for detecting early-stage skin cancer without requiring a tissue biopsy from the patient.

Killing bacteria by hacking plastics with silver and electricity
Researchers at the Swedish Medical Nanoscience Center at Karolinska Institutet have developed an innovative way of hacking conducting plastics so as to prevent bacterial growth using silver nanoparticles and a small electrical current. The method, which could prove to be useful in preventing bacterial infections in hospitals, is presented in the scientific journal Advanced Healthcare Materials.

Bioprinted veins reveal new drug diffusion details
Artificially constructed human tissues and organs have been developed with a number of different purposes in mind, from advanced robotics and novel materials to drug screening. The precision demanded by drug screening applications puts especially large demands on how accurately biomimetic constructs replicate tissue characteristics and behaviors involved in drug absorption.

Smaller, smarter, softer robotic arm for endoscopic surgery
Flexible endoscopes can snake through narrow passages to treat difficult to reach areas of the body. However, once they arrive at their target, these devices rely on rigid surgical tools to manipulate or remove tissue. These tools offer surgeons reduced dexterity and sensing, limiting the current therapeutic capabilities of the endoscope.
