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.

3-D printed models could improve patient outcomes in heart valve replacements


Heart valve models created with advanced 3-D printers could soon assist cardiologists in preparing to perform life-saving heart valve replacements. Researchers at Georgia Institute of Technology and Piedmont Heart Institute are using standard medical imaging and new 3-D printing technologies to create patient-specific heart valve models that mimic the physiological qualities of the real valves.

New flu test: one drop of blood could save your life


Australian researchers have developed a world first test to identify which influenza patients will need urgent, life-saving, medical treatment. The High-risk Influenza Screen Test (HIST) measures 'an early warning signal' released by the patient's body into their blood to 'kick start' their immune system's fight against the infection.

Using light to reach higher precision in cell mechanic research


Not only muscle cells, but also all other cell types continually generate forces in the human body. An interdisciplinary cooperation of biologists and physicists including Heidelberg researcher Prof. Ulrich Schwarz now succeeded in performing high-resolution measurements of cell forces using light to switch them on and off in a controlled manner.

Biofilm discovery suggests way to prevent infections


Microbial biofilms - dense, sticky mats of bacteria that are hard to treat and can lead to dangerous infections - often form in medical equipment, such as flexible plastic tubing used in catheters or in tubes used to help patients breathe. By some estimates, more than 1 million people contract infections from medical devices in U.S. hospitals each year, many of which are due to biofilms.
