MIT Scientists Are Building Biomedical Research Labs Out of LEGO Blocks

When it comes to microfluidics, precision is everything. Researchers in this field—which analyzes the behavior and control of tiny amounts of fluids— can use a miniscule, flat chip etched with channels (a "lab-on-a-chip") to control the mixing of liquids at a microscopic level. Now, Co.Design reports that MIT scientists have invented a system that achieves the same results using material that most people would recognize: LEGO blocks.

In their study published in the journal Lab on a Chip, the scientists explain how LEGO fits perfectly into their research. They started out carving grooves into LEGO bricks about 500 microns wide—about the width of handful of human hairs—and sealing them with clear film. Next, they built pathways for fluids by interlocking the blocks so the end of one channel lined up with the start of another.

Assembling a custom microfluidics lab this way takes seconds, which is nothing compared to the involved and costly process of building a lab-on-a-chip from scratch. The same blocks used in one configuration can also be deconstructed and rearranged to create a whole new design. As is the case with the traditional chips, the LEGO-based lab can be used in biomedical research to filter fluids, sort cells, and isolate molecules.

The scientists didn't choose LEGO blocks just because they're fun—they're also practical. The plastic toy blocks are some of the most uniform materials available for building modular systems. The molds used in LEGO factories have to meet strict standards, so only 18 pieces of every million created are technically imperfect.

But LEGO toys aren't the ideal building blocks for every microfluidics study. They don't work for experiments performed on the nano-level, and their plastic structure isn't tough enough to stand up to some chemicals. The MIT scientists are looking into developing protective coatings and possibly molding their own LEGOs from stronger materials to open the door to even more research in the future.

8 Great Gifts for People Who Work From Home

World Market/Amazon
World Market/Amazon

A growing share of Americans work from home, and while that might seem blissful to some, it's not always easy to live, eat, and work in the same space. So, if you have co-workers and friends who are living the WFH lifestyle, here are some products that will make their life away from their cubicle a little easier.

1. Folding Book Stand; $7

Hatisan / Amazon

Useful for anyone who works with books or documents, this thick wire frame is strong enough for heavier textbooks or tablets. Best of all, it folds down flat, so they can slip it into their backpack or laptop case and take it out at the library or wherever they need it. The stand does double-duty in the kitchen as a cookbook holder, too.

2. Duraflame Electric Fireplace; $179

Duraflame / Amazon

Nothing says cozy like a fireplace, but not everyone is so blessed—or has the energy to keep a fire going during the work day. This Duraflame electric fireplace can help keep a workspace warm by providing up to 1000 square feet of comfortable heat, and has adjustable brightness and speed settings. They can even operate it without heat if they just crave the ambiance of an old-school gentleman's study (leather-top desk and shelves full of arcane books cost extra).

3. World Explorer Coffee Sampler; $32

UncommonGoods

Making sure they've got enough coffee to match their workload is a must, and if they're willing to experiment with their java a bit, the World Explorer’s Coffee Sampler allows them to make up to 32 cups using beans from all over the world. Inside the box are four bags with four different flavor profiles, like balanced, a light-medium roast with fruity notes; bold, a medium-dark roast with notes of cocoa; classic, which has notes of nuts; and fruity, coming in with notes of floral.

4. Lavender and Lemon Beeswax Candle; $20

Amazon

People who work at home all day, especially in a smaller space, often struggle to "turn off" at the end of the day. One way to unwind and signal that work is done is to light a candle. Burning beeswax candles helps clean the air, and essential oils are a better health bet than artificial fragrances. Lavender is especially relaxing. (Just use caution around essential-oil-scented products and pets.)

5. HÄNS Swipe-Clean; $15

HÄNS / Amazon

If they're carting their laptop and phone from the coffee shop to meetings to the co-working space, the gadgets are going to get gross—fast. HÄNS Swipe is a dual-sided device that cleans on one side and polishes on the other, and it's a great solution for keeping germs at bay. It's also nicely portable, since there's nothing to spill. Plus, it's refillable, and the polishing cloth is washable and re-wrappable, making it a much more sustainable solution than individually wrapped wipes.

Buy It: Amazon

6. Laptop Side Table; $100

World Market

Sometimes they don't want to be stuck at a desk all day long. This industrial-chic side table can act as a laptop table, too, with room for a computer, coffee, notes, and more. It also works as a TV table—not that they would ever watch TV during work hours.

Buy It: World Market

7. Moleskine Classic Notebook; $17

Moleskin / Amazon

Plenty of people who work from home (well, plenty of people in general) find paper journals and planners essential, whether they're used for bullet journaling, time-blocking, or just writing good old-fashioned to-do lists. However they organize their lives, there's a journal out there that's perfect, but for starters it's hard to top a good Moleskin. These are available dotted (the bullet journal fave), plain, ruled, or squared, and in a variety of colors. (They can find other supply ideas for bullet journaling here.)

Buy It: Amazon

8. Nexstand Laptop Stand; $39

Nexstand / Amazon

For the person who works from home and is on the taller side, this portable laptop stand is a back-saver. It folds down flat so it can be tossed into the bag and taken to the coffee shop or co-working spot, where it often generates an admiring comment or three. It works best alongside a portable external keyboard and mouse.

Late MythBusters Star Grant Imahara Honored With New STEAM Foundation

Fans of MythBusters and White Rabbit Project host Grant Imahara were saddened to hear of his passing due to a brain aneurysm in July 2020 at the age of 49. Imahara, a graduate of the University of Southern California, used the television medium to share his love of science and engineering. Now, his passion for education will continue via an educational foundation developed in his name.

The Grant Imahara STEAM Foundation was announced Thursday, October 23, 2020 by family and friends on what would have been Imahara’s 50th birthday. The Foundation will provide mentorships, grants, and scholarships that will allow students from diverse backgrounds access to STEAM education, which places an emphasis on science, technology, engineering, arts, and math. (Formerly referred to as STEM, the “A” for art was added more recently.)

Imahara had a history of aiding students. While working at Industrial Light and Magic in the early 2000s, he mentored the robotics team at Richmond High School to prepare for the international FIRST Robotics Competition. Whether he was working on television or behind-the-scenes on movies like the Star Wars prequels and The Matrix sequels, Imahara always found time to promote and encourage young engineering talent.

The Grant Imahara STEAM Foundation’s founding board members include Imahara’s mother, Carolyn Imahara, and close friends Don Bies, Anna Bies, Edward Chin, Fon H. Davis, Coya Elliott, and Ioanna Stergiades.

“There are many students, like my son Grant, who need the balance of the technical and the creative, and this is what STEAM is all about,” Carolyn Imahara said in a statement. “I’m so proud of my son’s career, but I’m equally proud of the work he did mentoring students. He would be thrilled that we plan to continue this, plus much more, through The Grant Imahara STEAM Foundation.”

Imahara friend Wade Bick is also launching an effort in concert with the USC Viterbi School of Engineering to name a study lounge after Imahara. Donations can be made here.

You can find out more about the foundation, and make a donation, on its website.
