Rutgers wastes 4 M. pounds of food per year APARNA RAGUPATHI CORRESPONDENT
In 2016, Rutgers—New Brunswick produced almost four million pounds of food scraps from all of the campus dining areas combined, said Dorothy Lee, a School of Environmental and Biological Sciences senior and president of RU Compost. Currently, the dining halls either send their food scraps to pig farms or put the scraps through digesters that liquify the food so it can be put down the drain, she said. Joe Charette, executive director of

Rutgers Dining Services, clarified this in a recent interview with Nolan Fehon, a School of Environmental and Biological Sciences firstyear and member of Students for Environmental Awareness. “According to Charette, all of the dining halls have a Somat Pulper that condenses the food into a pulp that is then taken to a local pig farmer. The effluent then goes down the drain and is beneficial because it cleans the pipes,” Fehon said. While the digesters can digest all of the food scraps and the pigs can SEE YEAR ON PAGE 4

Members of Rutgers University Career Services (UCS) hope to help students on their career paths with the Rutgers Internship and Coop Program (RICP), emphasizing internships as a good first step. Director of Career Exploration and Experiential Education Sue Pye said those at UCS define internships as “professional level experience SEE CO-OPS ON PAGE 4
Research reveals new role for brain signals RYAN HALSTATER CONTRIBUTING WRITER
The mice used in the study were roughly half the size of an adult’s cupped hands, with a short white device that resembled an antenna sticking out of its head. The structure of a mouse’s brain is relatively similar to that of an adult’s. WIKIMEDIA COMMONS
Researchers at the Margolis Lab, which is in the Depar tment of Cell Biology and Neuroscience, have discovered a new dif ference in the behavior of mice when dif ferent par ts of the brain are stimulated. “We were interested in understanding how different sensory inputs can affect how mice respond to a particular sensory input or sensory stimulus,” said Christian Lee, the study’s lead author and research associate.
The structure of the parts of the brain studied are largely similar between mice and humans, Lee said. The part of the brain that the study focused on was the cortex, which is involved in motor control and transforming sensory input into action. In the study, researchers found that mice trained to respond to texture tend to respond more when their motor cortex, which is the part of the brain that controls movement, was activated compared to their sensory cortex, which is SEE SIGNALS ON PAGE 5
Metamaterials advance 3D printing into newly created 4D technology CHRISTIAN BALBUENA CONTRIBUTING WRITER
The pinnacle in the realm of creation just a few years ago was 3D printing. Now, researchers in the Department of Aerospace and Mechanical Engineering at Rutgers University have discovered a new frontier in 4D printing. Chen Yang, a graduate student and researcher, said that “4D printing is 3D printing with shape transformation capability over time.” This means that this new technology, unlike the stiff plastics created though 3D printing, is able to create complex machinery. This innovation in printing technology was not so much due to the printer itself evolving, but the
materials used for the printing itself advancing, he said. These new materials are known as metamaterials, which are described by Yang as “materials engineered to exhibit unusual and counter intuitive properties … The name ‘metamaterials’ is from the Greek word ‘meta,’ meaning ‘higher’ or beyond.” The use of metamaterials will give way to machines that were physically impossible though conventional means. “We combine design of metamaterials, shape-memor y polymer and 3D printing to create tunable metamaterials,” Yang said. “Previous metamaterials didn’t have the tunability in mechanical
proper ties and flexibility of shape transformation. But it will soon give way to new innovations that allow machines to adapt to cer tain situation if need be.” Yang also said the tunable metamaterials we created can be potentially used in shock absorption mechanism, morphing airplane or drone wings and soft robotics. When using shock absorption mechanisms, for example in a car, it can tune to absorb the shock for safety and comfor t. When using it in airplane wings, it can morph to optimize drag force. In soft robots, it can deform to adapt to environmental constraints. SEE TECHNOLOGY ON PAGE 5
Despite the name, 4D printing is essentially 3D printing, except that the materials are more flexible. The process of 4D printing also involves temperature. WIKIMEDIA COMMONS
