New technique illuminates DNA helix

Cornell researchers have identified a new way to measure DNA torsional stiffness—how much resistance the helix offers when twisted—information that can potentially shed light on how cells work.

Study: How cells and tissues maintain their shape

Scientists have long pondered how the body's tissues maintain their stiffness in the face of growth, injury, and other forces. In a new study, Yale researchers have described this mysterious process, which is key to healthy ...

Acoustic waves can monitor stiffness of living cells

MIT engineers have devised a new, noninvasive way to measure the stiffness of living cells using acoustic waves. Their technique allows them to monitor single cells over several generations and investigate how stiffness changes ...

The smallest steerable catheter

Scientists have developed a very small magnetic steerable catheter for minimally invasive surgery. Thanks to its variable stiffness, surgeons can perform more complex movements inside the body with a lower risk of injury ...

Ionizing radiation found to soften tumor cell microenvironment

Nearly half of all cancer patients receive radiation therapy to curb the growth of malignant cells. But little is known about how ionizing radiation affects the extracellular matrix (ECM), a patchwork of proteins and other ...

Origami-inspired self-locking foldable robotic arm

A research team of Seoul National University led by Professor Kyu-Jin Cho has developed an origami-inspired robotic arm that is foldable, self-assembling and also highly-rigid. (The researchers include Suk-Jun Kim, Dae-Young ...
