"Cancer Immunotherapy Channeled via Remote Control"
We're a long way from controlling our immune systems as easily as we might change the channels on our televisions, but a new remote-control system, in the hands of clinicians, could enable the narrowcasting of immunotherapies. For example, cancer immunotherapies could be "switched on" in solid tumors and "switched off" in healthy tissues. The new remote-control system, then, could avoid the toxicities associated with the broadcasting of cancer immunotherapy throughout the body.

"Cancer-fighting cells activated with ultrasound"
UC San Diego-led researchers have developed cancer-killing immune cells activated by ultrasound. Their work in cell cultures could lead to more precise cancer treatment with fewer side effects. Cells can be activated at up to 10 centimeters (nearly 4 inches), reaching deep with the body. The ultrasound method could be applied to other biological functions, either for research or clinical applications.

"How immune cells can be controlled to kill cancer"
By engineering cancer-killing T cells that can be manipulated noninvasively by remote control, researchers have added a potentially powerful feature to an already promising type of immunotherapy known as CAR T cell therapy. In their journal report, Prof. Wang and colleagues describe how they added new features to CAR T cell therapy in which the T cells carry modules that can be manipulated to produce gene and cell changes through remotely controlled and noninvasive ultrasound.

"You won't believe just how sensitive our sense of touch is"
Our sense of touch is so sensitive that we can feel the difference of just a single layer of molecules, researchers have found. We can easily tell the difference between a range of surfaces, from the roughest of sand paper to a soothing caress. We read eye charts to test our visual acuity before getting behind the wheel of a car. Newborns take simple audio tests to check that they can hear before they go home with their parents. But in comparison, our sense of touch has been a bit neglected. Recently, researchers in California put our tactile sense to the test.
