LiquiGlide, an MIT startup, has announced several new partnerships aimed at developing sustainable, zero-waste packaging solutions, reports Janelle Nanos for The Boston Globe. “LiquiGlide wants to fix one of life’s longstanding frustrations: trying to squeeze out the end of a toothpaste tube,” writes Nanos. “Since it’s often difficult to empty out sticky pastes, gels, and creams, hundreds of millions of dollars worth of those substances are discarded annually, still stuck to the insides of their containers.”

Prof. Kripa Varanasi speaks with Boston 25 reporter Jim Morelli about a food-safe coating, called LiquiGlide, that makes it possible to squeeze every drop out of containers of items like ketchup and toothpaste. “It’s a universal kind of a problem,” Varanasi says. “The interface between the liquid and the solid is what makes these products stick to containers.”

Gizmodo reporter Andrew Liszewski writes that LiquiGlide, an MIT startup, is working with Colgate to introduce a “new recyclable toothpaste container that leverages LiquiGlide so that every last drop of the product can be squeezed out with minimal effort.”

MIT researchers have developed a new robot, dubbed RF Grasp, that can sense hidden objects using radio waves, reports Brian Heater for TechCrunch. “The tech allows RF Grasp to pick up things that are covered up or otherwise out of its line of vision,” writes Heater.

MIT researchers have created a new filter from tree branches that could provide an inexpensive, biodegradable, low-tech option for water purification, writes Shaena Montanari for Popular Science. “We hope that our work empowers such people to further develop and commercialize xylem water filters tailored to local needs to benefit communities around the world,” says Prof. Rohit Karnik.

7 News reporter Byron Barnett spotlights how MIT researchers are developing new face masks aimed at stopping the spread of Covid-19. Prof. Giovanni Traverso is creating reusable masks with pop-put disposable filters, and Prof. Michael Strano is developing a mask that could “destroy the virus, using a nine-volt battery to heat the mask and kill the virus before the wearer breathes it in.”

Wall Street Journal reporter Suzanne Oliver spotlights two MIT efforts to innovate the face mask. Prof. Giovanni Traverso and his colleagues are developing a reusable, silicon-rubber mask with “sensors that give feedback on fit and functionality,” while Prof. Michael Strano has designed a version that “incorporates a copper mesh heated to about 160 degrees that traps and deactivates the virus.”

UPI reporter Brooks Hays writes that MIT researchers have created a new water filter from tree branches that can remove bacteria. “The filter takes advantage of the natural sieving abilities of xylem -- thin, interconnected membranes found in the sapwood branches of pine, ginkgo and other nonflowering trees,” writes Hays.

Prof. Gio Traverso speaks with CNN’s Jeanne Moos about his new study examining how comfortable patients were interacting with Dr. Spot, a robotic dog outfitted with a computer tablet that allows ER doctors to engage with patients remotely. “The robot looks like a dog, and dogs are endearing to many, so actually, the reception was very positive,” said Traverso.

NY Post reporter Asia Grace writes that MIT researchers have found that patients are comfortable with allowing robotic assistants perform medical evaluations, as part of an effort to help reduce the spread of Covid-19. “People are very positive and accepting of robotic systems in health-care settings, particularly during the pandemic,” says Prof. Giovanni Traverso.

UPI reporter Brooks Hays writes that MIT researchers have developed a new technique for turning plastic into a wearable material. “Engineers at MIT have managed to weave polyethylene into fibers that absorb and evaporate water more quickly than cotton, nylon, polyester and other common textiles,” writes Hays. “The authors of the new paper hope their technology will incentivize plastic recycling.”

BBC News reporter Helen Briggs writes that MIT researchers have developed a technique to create fabrics from polythene, a plastic found in food packaging and plastic bags. "There's no reason why the simple plastic bag cannot be made into fibre and used as a high-end garment," says research scientist Svetlana Boriskina. "You can go literally from trash to a high-performance garment that provides comfort and can be recycled multiple times back into a new garment."

Graduate student Ashley Beckwith speaks with BBC Radio 5 about her work developing a new concept for growing wood in the lab, as part of an effort to supplement traditional forestry methods. "We dedicate a lot of resources to growing whole plants, when all we use really is a very small portion of the plant,” says Beckwith. “So somehow we needed to figure out a more strategic way to reproduce materials that isn't so reliant on the land."

Writing for Wired, Keith Gillogly spotlights how MIT researchers have devised a new technique that could lead to the development of lab-grown wood and other biomaterials. “The hope is that, if this becomes a developed process for producing plant materials, you could alleviate some of [the] pressures on our agricultural lands. And with those reduced pressures, hopefully we can allow more spaces to remain wild and more forests to remain in place,” says graduate student Ashley Beckwith,

Popular Mechanics reporter Kyro Mitchell explores how MIT researchers have created a biodegradable medical patch that could be used to repair internal injuries. Mitchell notes that the patch “can be easily wrapped around robotic tools like a balloon catheter and a surgical stapler and then be inserted into the patient.”
