MIT researchers have found that mechanical training could be used to produce synthetic hydrogels that perform more like human muscles, reports Sam Spiller for Popular Mechanics. “Stretched and treated to a mechanical workout in a water bath, the [hydrogels] became unyielding and resistant to molecular ruptures,” writes Spiller. “They were able to stay structurally sound despite continuous repetitive movements.”
New Scientist reporter Andy Coghlan writes that MIT researchers have engineered bacteria to produce full-color, living photocopies. Coghlan explains that the technique could “enable finer control of the bacteria grown in fermenters to churn out vital drugs, antibodies and materials. Another application could be using light to sculpt living biomaterials, such as tissues and organs for transplant.”
In this “Science of Innovation” segment, NBC Learn explores Prof. Angela Belcher’s work using viruses engineered in her laboratory to form nanoscale wires for tiny batteries. “By harnessing nature’s own processes, Angela Belcher has been able to turn today’s viruses into tomorrow’s batteries.”
Writing for Popular Science, Lindsey Kratochwill reports that MIT researchers have discovered that the hundreds of eyes on a chiton's shell can see. Kratochwill explains that the researchers hope that by “understanding how these eyes work and the materials that make them up could lead to manmade materials that are both protective and perceptive of their environments.”
Atlantic reporter Ed Yong writes that MIT researchers have found that chitons, a type of mollusk, have a suit of armor dotted with hundreds of eyes that can perceive objects. The researchers found that chitons could “detect the shape of a 20-centimeter fish from a few meters away.”
Graduate student Eric Arndt discusses his research on the bombardier beetle’s ability to produce a boiling-hot stream of liquid on the PBS program SciTech Now. “Insects, as it turns out, are very good material scientists,” explains Arndt. “Just studying these fundamental systems has the possibility of opening up all kinds of doors in all kinds of industries.”
In a Boston Globe article about the high level of patent activity in Massachusetts, Emeralde Jensen-Roberts highlights MIT postdoctoral fellow Keith Hearon’s work developing a new type of biodegradable styrofoam, which he is patenting. “Now in the development phase, Hearon believes the citrus plastic with styrofoam has vast potential for larger-scale applications, thanks to its strength.”
A team led by Professor Markus Buehler has created a device that can produce spider silk, writes Andrea Alfano for the Tech Times. Buehler explains that silk produced by this new device is, “a lot more modifiable than spider silk,” and could be used to create synthetic organs.
Sindya Bhanoo writes for The New York Times that MIT researchers have discovered how the bombardier beetle produces blasts of a hot, lethal toxin to fend off predators. “The beetle has a really complicated explosion system that’s all connected together,” explains Prof. Christine Ortiz.
MIT researchers have figured out how the bombardier beetle can fire off chemicals when threatened, writes Washington Post reporter Rachel Feltman. Feltman explains that the researchers used “high-speed x-ray imaging” to examine the beetle’s defense mechanisms in action.
By examining X-ray images, MIT researchers have uncovered how bombardier beetles are able to produce “machine-gun style” blasts of chemicals to fend off predators, reports Andy Coghlan for New Scientist. “The researchers were surprised to find that a passive mechanism generates the pulses,” Coghlan explains.
New MIT research offers a detailed look at how the bombardier beetle produces the scalding black liquid it expels as a defense mechanism, writes Brooks Hays for UPI. “The process operates almost like an assembly line of chambers and valves -- chemicals mixed, pressure builds, chemical released in jet-like spray through valve, relax and repeat.”
Kevin Hartnett of The Boston Globe looks at Professor Christine Ortiz’s work to develop better body armor technology by mimicking the tough qualities of fish scales. “Armored fish have multi-hit capability,” explains Ortiz. “Basically, when it gets hit, it just cracks locally in a circle.”
