'Aneurysm Number' may help surgeons make treatment decisions

Aneurysms form as abnormal bulges or balloonings over an artery, and, if ruptured, can lead to serious health complications or even death. Some aneurysms can exist for a long time without rupturing, and the surgery involved ...

Measuring stress around cells

Tissues and organs in the human body are shaped through forces generated by cells, that push and pull, to "sculpt" biological structures. Thanks to a new tool developed at McGill University, scientists will now be able to ...

Scientists discover how mechanical strain shapes plants

Scientists from Nanyang Technological University, Singapore (NTU Singapore) and Carnegie Mellon University in the U.S. have discovered how mechanical forces can influence the shapes of plant leaves and flower petals.

A hydrogel that adheres firmly to cartilage and meniscus

EPFL researchers have developed a hydrogel – made up of nearly 90% water – that naturally adheres to soft tissue like cartilage and the meniscus. If the hydrogel carries repair cells, it could help damaged tissue to heal.

Titanium dioxide as a nanoscale sensor of mechanical stress

Scientists from EPFL, Germany and France have revealed a new property of the cheap and abundant material anatase titanium dioxide, which promises applications as a medium for room-temperature nanosensors of mechanical stress ...
