The Future of 3D Printing and Healthcare

When it comes to 3D printing, the sky is the limit. As 3D printing technology continues to advance, applications can be as far reaching as  airplane  and  automobile parts  to medical devices and even anatomically correct, biocompatible models. Although 3D printing technology is developing at a rapid pace, the technology itself is not new. It emerged in  the 1980s  as a means of creating rapid prototypes. In recent years the applications for 3D printed models have evolved with the available hardware, software, and printable materials. Evolving technology, paired with the creative and innovative minds of scientists, engineers, and physicians, has been the launching pad for developments within 3D printing technology specific to healthcare. One way 3D printing technology is poised to create better patient outcomes is in creating an anatomically and  patient-specific models  to aid in surgery and medical procedures. With the capability to 3D print patient-specific models, more acc

High-Tech Toothbrush Corrects Common Brushing Errors

There are few things more routine than brushing your teeth: At least twice a day, every day, you stand in front of the mirror and go through the motions. So it might come as a surprise to learn that most people are probably doing it wrong. Now, a uniquely designed toothbrush aims to guarantee that brushers get it right.
Most people have heard that they should brush their teeth for at least 2 minutes, twice a day. But it's perhaps less well-known that the way you brush is just as important. The American Dental Association recommends holding the toothbrush at a 45-degree angle away from the gums and brushing in short, downward strokes.
More commonly, people hold their toothbrushes perpendicular to their teeth and gums, said Alexander Kandemir, inventor of the new iBrush 365. The gums should make a tight seal with the teeth, but holding a toothbrush perpendicular to the teeth pushes the gums upward and makes them start to pull away, he added. This makes brushing less effective and can contribute to oral problems like gum disease.
The new iBrush 365 aims to correct bad brushing behavior by allowing people "to brush in ways the dentist wants, without changing our old habits," Kandemir told Live Science. The electrical toothbrush has a cylindrical head that is loaded with more than 13,000 soft "micro bristles" (compared to the 2,500 bristles in a standard toothbrush) that can effectively clean the entire mouth in less than a minute.
In practice, using the brush feels a lot like using a regular electric toothbrush. You hold it perpendicular to your teeth and move it from side to side. The rotating head ensures that teeth are brushed in a downward direction and that the bristles are at a 45-degree angle to the gums, the company said. The toothbrush's head can rotate in either direction, changing with a simple push of a button so that the movement is always directed downward.
The cylindrical head also cleans more than just the teeth. "Clean teeth doesn't mean a clean mouth," Kandemir said. "You need to brush your gums, tongue, and cheeks, too."
The iBrush 365 was tested on more than 300 people, and Kandemir said the results show that the device is the most effective brush on the market.
The iBrush 365 is equipped with a lithium-ion battery that lasts six weeks on a single charge, the company said. Users can charge the device with a USB power cord and a universal wall plug that works from 110 to 240 volts.
The project raised more than $29,000 through a crowdfunding campaign on Kickstarter. The brush is now available for preorder on the company's website for $79, and orders will begin shipping this month.

Phthalates and BPA Regulations: Are We There Yet?

It’s better to be safe than sorry.  But the Environmental Protection Agency  recently withdrew two proposed rules regulating chemicals  that it had developed under authority of the Toxic Substances Control Act (TSCA) and submitted to the White House’s Office of Information in 2010 and 2011.  Dr. Richard Deninson  of the Environmental Defense Fund explains it further: Faced presumably with the reality that OIRA [Office of Information and Regulatory Affairs] was never going to let EPA even propose the rules for public comment, EPA decided to withdraw them.  The two proposed rules that were just withdrawn would have: Designated as ‘chemicals of concern’ three classes of chemicals for which evidence is more than sufficient to warrant such a designation:  bisphenol A (BPA), a category of phthalates, and a category of polybrominated diphenyl ethers (PBDEs).  By listing a chemical as ‘of concern,’ EPA may obtain, and provide to the public, more information about the chemical than it

The Science Behind 4 Of The Greatest Polymers Of All Time

PMMA Applications: Lucite, dentures, aquarium windows Developed in: 1877 Polymethylmethacrylate is a very versatile polymer. If you ever see a clear plastic block, it's probably PMMA. It was first commercialized in the 1930s in Germany, and is now found anywhere one needs clear, strong material. This includes bulletproof "glass" at your favorite corner liquor store and the huge shark tanks at the Monterey Bay Aquarium. But my favorite use of PMMA is in so-called "frozen lightning" or Lichtenberg figure sculpture. Basically, put a chunk of PMMA into an electron accelerator, fire a bunch of electrons into the plastic until it's got about two million volts of charge, then touch the side of the plastic with a bit of wire and watch as bolts of lightning carve tracks inside the clear plastic. Superabsorbers Applications: Diapers Developed in: 1960s Back in the day, diapers were made from cloth. Frequently, those cloth diapers were filled with wads of n

Virginia Tech Students Create Foldable Bike Helmets

Helmets: Something you may have hated with a passion as a child, but your parents made you wear. As adults, one could argue helmet use is pretty divided. If you head down your local bike path or along a neighborhood street, you’ll see a good number of riders not wearing their helmets. Two Virginia Tech students think that’s a problem. Co-founders David Hall and Jordan Klein started  Park & Diamond  and set out to create a safe, compact, and stylish helmet to hopefully convince people to wear them every time they bike. The interest in refining technology to prevent bike related head injuries is  incredibly personal  for the team of innovators, especially for Hall. In 2015 Hall’s younger sister was involved in a bike accident in Philadelphia and remained in a coma for four months. The bicycle crash occurred at the corner of Park Avenue and Diamond Street in Philadelphia—which is reflected in the name of their company. How Helmets Work Just like the  crumple zone  in y
