vibration

Vibration-absorbing, sound-damping materials such as sheets of rubber and expanded foam tend to be thick, bulky and soft. A new material is a big exception to that tendency, however, as it absorbs vibrations while staying stiff and thin.

Checking on bee health is normally an invasive process that risks harming the colony, particularly the queen. Now, researchers have found that a new method, when combined with sound recording, can let beekeepers see just how healthy their honey-makers are.

Scientists have demonstrated an intriguing new technique to treat cancer – “molecular jackhammers” that latch onto cancer cells, then vibrate vigorously to kill them when activated by infrared light.

The FDA has granted clearance to a novel, wearable belt that delivers targeted vibrations to the spine and hips to treat low bone density, the precursor to osteoporosis, making it the first non-drug prescription medical device to treat the condition.

The stomach signals the brain to say when you’ve had enough to eat – although we ignore it at the holidays. MIT scientists have found a way to hijack that mechanism with a vibrating pill that can help reduce appetite and potentially treat obesity.

For the past year or so, a student team from the Eindhoven University of Technology has been working on a wearable that could allow folks to understand what's being said in another language through vibrations on the arm.
