Injections At Supersonic Speed, Without Needles

Alternatives to needle injections have been sought after for many years, and the results have had varying degrees of success. A team of scientists think they've come up with a solution.

What's the Latest Development?

Researchers at the University of Twente in the Netherlands say they've come up with a method of drug injection that may be a viable alternative to needles. With the help of a laser pulse, tiny shockwaves expel a microjet of liquid at a speed of up to 2000 miles per hour -- about as fast as a supersonic jet -- easily penetrating the skin and delivering a precise amount into the body. 

What's the Big Idea?

Needles are by far the preferred method of injecting drugs, but they have their downsides, including possible disease transmission. Various alternatives have been developed and used over the years, many of which involve the same technique of forcing liquid into the body via some sort of pressure. Unfortunately if the dose isn't delivered properly, splashing can occur, ruining the injection. The amount of force used can also damage the skin. Concerning its method, the team still has additional research to do, including testing on a variety of actual people: So far the only tests have been done on gelatin covered with synthetic skin.

Politics & Current Affairs

For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
