Artificial intelligence predicts dementia before onset of symptoms


Imagine if doctors could determine, many years in advance, who is likely to develop dementia. Such prognostic capabilities would give patients and their families time to plan and manage treatment and care. Thanks to artificial intelligence research conducted at McGill University, this kind of predictive power could soon be available to clinicians everywhere.

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.

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.
