How Blobs of Sea Snot Help Keep Our Oceans Clean

There’s so much in our oceans we have yet to explore—in part because life down there is so weird that we can’t even figure out how to study it. Now scientists have made some progress with new technology that lets them peek inside one strange animal’s floating, goopy house. The team described their progress in the journal Science Advances.

The giant larvacean (genus Bathochordaeus) is a bizarre critter. Unlike better-known filter feeders like baleen whales, Bathochordaeus has a little mouth, so it’s taken to outsourcing the actual filtration process. Every day, the larvacean blows an enormous, sticky mucus balloon, which snags all kinds of morsels as the animal drifts through the water column.

Each trapped morsel contains a little bit of carbon. After the larvacean eats its fill, it discards the now-cluttered snot bubble, which sinks, thereby bearing some of that carbon out of circulation and onto the sea floor. These delicate mucus houses are quite beautiful, in their way. But they’re also kind of a pain to study, as they tend to disintegrate at the slightest touch. Grabbing one in a net or jar has proven almost impossible.

Oceanographers at the Monterey Bay Area Research Institute (MBARI) decided to take a more hands-off approach. They adapted a technology called particle image velocimetry (PIV), which is commonly used to study the movement and flow of water. They attached a PIV laser and a camera to a miniature remotely operated vehicle (ROV) and sent it down, down, down into the depths off the California coast. When the ROV’s camera spotted a larvacean, the researchers activated the laser, which spread a sheet of light over the animal and its dwelling, illuminating every particle within.

“We were all shocked by how well it worked,” principal engineer Kakani Katija said in a statement. “There was a lot of oohing and aahing in the control room. It wasn’t just the scientists who were shocked and amazed—it was everyone on the research vessel.”

The researchers are excited to apply their new technology to all kinds of deep-sea research.

“Now that DeepPIV is available to the oceanographic community,” Katija said, “it opens up all kinds of possibilities.”

Now that Prime Day is over, and with Black Friday and Cyber Monday still a few weeks away, online deals may seem harder to come by. And while it can be a hassle to scour the internet for promo codes, buy-one-get-one deals, and flash sales, Amazon actually has an extensive coupon page you might not know about that features deals to look through every day.

As pointed out by People, the coupon page breaks deals down by categories, like electronics, home & kitchen, and groceries (the coupons even work with SNAP benefits). Since most of the deals revolve around the essentials, it's easy to stock up on items like Cottonelle toilet paper, Tide Pods, Cascade dishwasher detergent, and a 50 pack of surgical masks whenever you're running low.

But the low prices don't just stop at necessities. If you’re looking for the best deal on headphones, all you have to do is go to the electronics coupon page and it will bring up a deal on these COWIN E7 PRO noise-canceling headphones, which are now $80, thanks to a $10 coupon you could have missed.

Alternatively, if you are looking for deals on specific brands, you can search for their coupons from the page. So if you've had your eye on the Homall S-Racer gaming chair, you’ll find there's currently a coupon that saves you 5 percent, thanks to a simple search.

To discover all the deals you have been missing out on, head over to the Amazon Coupons page.

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.
