Forbes reporter Amanda Kooser spotlights a new study by MIT scientists that has found eggs are less likely to crack when dropped on their side. “The researchers put eggs through their paces in two different tests,” explains Kooser. “One was a static compression test that applied increasing force to the eggs. The other was a drop test.”
Researchers at MIT have discovered that eggs dropped on their side are less likely to crack than those dropped on their tips, reports Doyle Rice for USA Today. The researchers conducted both a drop and compression test on the eggs, and the findings “suggest that future research could explore the application of these findings to engineering scenarios, such as how structures respond to dynamic loads,” writes Rice.
A study by MIT researchers has found that “dropping an egg horizontally is more likely to keep it intact than a vertical drop,” reports Ed Cara for Gizmodo. “People tend to have better intuition for stiffness and strength, which are important in statics,” explains Prof. Tal Cohen. “It is common that they refer intuitively to the redistribution of a load along the arch. However, when dynamics are involved, toughness is also an important quantity.”
MIT researchers have discovered that “eggs are less likely to crack when they fall on their side,” reports Adithi Ramakrishnan for the Associated Press. “It’s commonly thought that eggs are strongest at their ends — after all, it’s how they’re packaged in the carton,” explains Ramakrishnan. “The thinking is that the arc-shaped bottom of an egg redirects the force and softens the blow of impact. But when scientists squeezed eggs in both directions during a compression test, they cracked under the same amount of force.”
Researchers at MIT have found that eggs dropped on their sides and not their tips are more resilient and less likely to crack, reports Veronique Greenwood for The New York Times. The researchers found that “eggs dropped so they landed on their sides were substantially less likely to crack,” writes Greenwood. “When they hit, the shell was able to compress, absorbing some of the blow. Eggs dropped on their ends, where the shell is stiffer, did not show such flexibility.
Six MIT faculty members – Prof. Emerita Lotte Bailyn, Prof. Gareth McKinley, Prof. Nasser Rabbat, Prof. Susan Silbey, Prof. Anne Whiston Spirn, and Prof. Catherine Wolfram – have been elected to the American Academy of Arts and Sciences, reports Sarah Mesdjian for The Boston Globe. “The academy aims to honor accomplished leaders in a wide array of fields and ‘cultivate every art and science which may tend to advance the interest, honor, dignity, and happiness of a free, independent, and virtuous people,’” explains Mesdjian.
Materials World reporter Sarah Morgan spotlights how MIT researchers have “combined the waterproof stickiness of mussel-inspired polymers with the germ-fighting properties of mucus-derived proteins, mucins, to form a cross-linking gel that strongly adheres to surfaces.” The new adhesive could be used to coat medical implants to prevent infection and bacteria build-up. Postdoc George Degen explains: “We demonstrate adhesion to wet tissue and metal-oxide surfaces, important substrates for biomedical applications. Moreover, our mucin-derived hydrogels discourage the formation of bacterial biofilms, raising the possibility of antifouling coatings.”
Researchers at MIT have developed a new technique to fabricate “a metamaterial that is both stretchy and strong,” reports Alex Knapp for Forbes. The researchers also discovered that their new fabrication technique can be applied to the development of new materials, Knapp explains, adding that: “future research will be directed toward developing stretchy glass, ceramics and textiles.”
Defense One reporter Patrick Tucker writes that MIT researchers have developed “a new way to make large ultrathin infrared sensors that don’t need cryogenic cooling and could radically change night vision for the military or even autonomous vehicles.” Tucker notes: “This research points to a new kind of vision: not just night vision without cooling, but a production method for faster and cheaper development of night vision equipment with more U.S. components.”
Prof. Amos Winter speaks with WBUR reporter Grace Griffin about his work developing a desalination system that relies on solar power. “The majority of water you find in the ground around the world is salty,” says Winter. “The reason we use solar power is that most people around the world are going to be resource-constrained. They may have lower income levels or not have access to grid electricity. So, our technology makes desalination much more accessible in all areas around the world.”
Syntis Bio, a biopharmaceutical company co-founded by Prof. Giovanni Traverso and Prof. Robert Langer, is developing a daily obesity pill that mimics the effects of gastric bypass, reports Emily Mullin for Wired. “This material is something you would take as a capsule or liquid, but the next day it's gone because of the natural turnover of our mucosal surface in the GI tract,” says Traverso.
A study by MIT researchers finds “using scrubbers to treat exhaust from heavy fuel oil may offer environmental performance on par with, and in some areas superior to, burning low-sulfur fuels in maritime shipping,” reports Hassan Ahmed for Engineeringness. “The research provides data that could help policymakers and industry leaders better assess the comparative costs and benefits of available fuel options,” explains Ahmed.
Kodiak Brush '17 speaks with Fast Company reporter Jesus Diaz about his work tackling football helmet design. The Apache helmet Brush designed for Light Helmets is the “lightest on the market—and yet it has achieved the highest safety score ever recorded by Virginia Tech’s independent helmet testing lab.” Diaz notes that for Brush, “success isn’t measured by sales figures or accolades—it’s about changing how people think about football safety and avoiding traumatic brain injuries.”
Researchers at MIT and elsewhere have developed a new robot aimed at assisting first-responders called SPROUT (short for Soft Pathfinding Robotic Observation Unit), reports WHDH. The robot has a built-in camera and motion sensors so that first responders could “scope out a site, before sending rescue teams in to save survivors.” The robot operates with a “soft, air-inflated tube that unfolds into small spaces,” explains WHDH. “It can maneuver around sharp corners in disaster zones.”
MIT engineers have developed a new system that helps pesticides adhere more effectively to plant leaves, allowing farmers to use fewer chemicals without sacrificing crop protection, reports Michigan Farm News. The new technology “adds a thin coating around droplets as they are being sprayed onto a field, increasing the stickiness of pesticides by as much as a hundredfold.”
