Ultrasound can selectively kill cancer cells

A new technique could offer a targeted approach to fighting cancer: low-intensity pulses of ultrasound have been shown to selectively kill cancer cells while leaving normal cells unharmed.

Adding memory to pressure-sensitive phosphors

Mechanoluminescence (ML) is a type of luminescence induced by any mechanical action on a solid, leading to a range of applications in materials research, photonics and optics. For instance, the mechanical action can release ...

Robotic gripping mechanism mimics how sea anemones catch prey

Most robotic gripping mechanisms to date have relied on humanlike fingers or appendages, which sometimes struggle to provide the fine touch, flexibility or cost-effectiveness needed in some circumstances to hold onto objects. ...

New method produces robust transistors

A new method to fit together layers of semiconductors as thin as a few nanometers has resulted in not only a scientific discovery but also a new type of transistor for high-power electronic devices. The result, published ...

Polymer-based optical fiber for visualization of material stress

Fiber-optic strain sensing is known for its ability to monitor large areas. However, most types of fiber-optic strain sensors require spectrum analysis instruments, which drastically increases the overall cost of sensor systems. ...
