Scientific American presents four toys that inspired innovations in science and technology. For example, University of Pittsburgh physicist Jeremy Levy had an Etch A Sketch in mind when developing a new way to fabricate nanoscale transistors. And UC Irvine biomedical engineer Michelle Khine used Shrinky Dink technology to make microfluidic systems for "labs on a chip." (Images above.) From Scientific American:
Khine knew that when Shrinky Dinks condense, any ink lines on the plastic become raised--and that's precisely what she sought in a microfluidics mold. She bought Shrinky Dink plastic designed for computer printer use, printed a pattern, and baked it for several minutes in her toaster oven. The results exceeded her expectations. Instead of just making molds, Khine ultimately developed a technique to make microfluidics chips directly from Shrinky Dink plastic. "It actually worked really well," Khine says, well enough to found a company based on that basic premise. To create products such as stem cell research devices and solar cells, Shrink Nanotechnologies has developed a new material that trumps the toy's abilities. Says Khine: "Shrinky Dinks shrink by 60 percent, but our new polymer shrinks 95 percent. And the properties shrink more consistently."
In 2009, President Obama pledged to “restore science to its rightful place.” He said, “We will not just meet, but we will exceed the level achieved at the height of the space race, through policies that invest in basic and applied research, create new incentives for private innovation, promote breakthroughs in energy and medicine, and […]
When I was little, my mother had a 1960s sit-under hair dryer with a huge translucent plastic hood that I’d imagine was a variation on a Star Trek Transporter. But that hulking machine had nothing on these vintage hair dryers from the first part of the 20th century. These would have provided me with years […]
In a new report, the U.S. Government Accountability Office reveals that the “Department of Defense uses 8- inch floppy disks in a legacy system that coordinates the operational functions of the nation’s nuclear forces.” That floppy format was developed in the late 1960s and was obsolete by the 1980s. I wonder if the DoD saves […]
Experienced shutterbugs with DSLR cameras have boatloads of lens options for capturing the moment. Unfortunately, smartphone photographers often get stuck with their one crummy lens, which means limited zoom and focus for their final image.Step up your smartphone’s photographic power with the Acesori 5-Piece Smartphone Camera Lens Kit, now just $9.99 in the Boing Boing Store.Magnetic rings easily […]
Some truths are universal. For one, your phone will always run out of power when you most need it. For another, the charging cords that come packaged with your Apple device will fray, split, and rip faster than Usain Bolt in a game of tag.Instead, pick up a charging cord that anyone would have a tough […]
Some people say magic tricks are nerdy and best left to your 12-year-old asthmatic cousin. But others see value in perfecting the slight of hand and showmanship associated with a perfectly executed routine. We’re firmly in the latter camp. And now, we’re giving you the ability to put a few parlor tricks up your sleeve with the Penguin […]
