Scientists at MIT have developed spinach plants that can detect and alert people about explosives, reports Matthew Gunther for Scientific American. Grad student Min Hao Wong explains that plants are good sensors as “through the transpiration process, plants draw up water and other analytes from the ground, and can accumulate even trace levels of analytes within [their] tissues.”
CBS News reporter Brian Mastroianni writes that MIT researchers have engineered spinach plants to serve as sensors by embedding the leaves with carbon nanotubes. Mastroianni explains that the researchers feel this work shows that “plants could ultimately serve as great collaborators in helping people better understand the environment around them.”
Washington Post reporter Sarah Kaplan writes that MIT researchers have developed bionic spinach plants that can detect explosives. Kaplan explains that the researchers were able to “turn plants into bomb-sniffing machines with the help of tiny cylinders of carbon that can detect ‘nitroaromatics’ — chemical compounds often used in explosives.”
Kate Samuelson writes for TIME that MIT engineers have created a method for turning spinach plants into bomb detectors that can wirelessly transmit warning signals. The research "opens the door to the use of wild-type plants for infrared communication in wide areas, and real-time monitoring of environments,” explains Samuelson.
MIT researchers have created bomb-detecting spinach by embedding fluorescent nanoparticles into the plant’s leaves, The Guardian reports. Plants are ideal for this detection system because they “have built-in power sources and are able to move fluids around very efficiently,” explains Prof. Michael Strano.
BBC News reporter Paul Rincon writes that by embedding carbon nanotubes into spinach leaves, MIT researchers have created plants that can detect explosives. “The plants could be used for defense applications, but also to monitor public spaces for terrorism related activities,” explains Prof. Michael Strano.
CSAIL researchers have a developed a system that can predict human emotions by using wireless signals to monitor breathing and heartbeats, writes Edd Gent in a Scientific American article. "The idea is that you can enable machines to recognize our emotions so they can interact with us at much deeper levels," says graduate student Fadel Adib.
CSAIL researcher have created a device that uses changes in heart beat and breathing to detect emotions, writes Forbes’ Kevin Murnane. The heart of the system,” writes Murnane, “is the algorithm that extracts the heartbeat from the RF signal. It’s an impressive achievement that solves a difficult problem.”
A device created by CSAIL researchers can detect emotions by wirelessly measuring heartbeats, according to the Associated Press. The device is “87 percent accurate in using heartrate and what it’s already learned about a person to recognize joy, pleasure, sadness or anger.”
CSAIL researchers have developed a device that can determine a person’s mood using wireless signals, write Jordan Graham and Donna Goodison for The Boston Herald. “We view this work as the next step in helping develop computers that can better understand us at an emotional level,” explains Mingmin Zhao.
CSAIL researchers have developed a device that can determine emotion by analyzing reflections from wireless signals bounced off the human body, writes Mary Beth Griggs for Popular Science. “Because it can measure heart rate, it might also be a less invasive way for doctors to monitor patient's heartbeats, potentially watching for conditions like arrhythmias,” writes Griggs.
Matt McFarland writes for CNN that CSAIL researchers have developed a non-invasive device that uses radio waves to detect human emotion. "Imagine if the machines around you can understand when you are stressed or your emotional state is negative,” explains Prof. Dina Katabi."[It could] try to detect depression."
MIT scientists have developed a device that can evaluate the ripeness of an apple by measuring the glow of chlorophyll in the fruit’s skin, writes Jesse Emspak for CBS News. “Such a gadget could make a big difference for apple distributors, who sometimes have to guess when deciding where to send their stock,” explains Emspak.
MIT researchers have developed a handheld sensor that can determine the ripeness of a piece of fruit, reports Deborah Netburn for The Los Angeles Times. The new device could “help farmers determine the optimal time to harvest fruit, or help them rapidly sort apples in storage facilities based on their ripeness.”
A new book by Prof. Carlo Ratti and graduate student Matthew Claudel focuses on the impact technology has on cities, writes Kate Abbey-Lambertz for The Huffington Post. “Ratti and Claudel envision a potential future where new technology ― from individualized heating grids to neighborhood 3D-printing fabrication studios ― ‘weaves into a tapestry of citizen empowerment’.”
