Getting a shot at the doctor's office may become less painful in the not-too-distant future.
Hate getting shots? Jet device works without needles

Massachusetts Institute of Technology researchers have engineered a device that delivers a tiny, high-pressure jet of medicine through the skin at the speed of sound, without the use of a hypodermic needle. The device can be programmed to deliver a range of doses to various depths — an improvement over similar jet-injection systems that are commercially available.
The researchers say that among other benefits, the technology may help reduce the potential for needle-stick injuries; the Centers for Disease Control and Prevention estimates that hospital-based health care workers accidentally prick themselves with needles 385,000 times each year. A needleless device may also help improve compliance among patients who might otherwise avoid the discomfort of regularly injecting themselves with drugs such as insulin.
