- Soundwaves Harden 3D-Printed Treatments in Deep Tissues - Engineers at Duke University and Harvard Medical School have developed a biocompatible ink that solidifies into different 3D shapes and structures by absorbing ultrasound waves. https://pratt.duke.edu/news/soundwaves-harden-3d-printed-treatments-in-deep-tissues/ 4 comments futurology
- Engineers have developed a biocompatible ink that solidifies into 3D shapes by absorbing ultrasound waves and, because it responds to sound waves rather than light, the ink can be used in deep tissues for biomedical purposes ranging from bone healing to heart valve repair https://pratt.duke.edu/news/soundwaves-harden-3d-printed-treatments-in-deep-tissues/ 11 comments science
- Using a gel-like, radioactive implant, engineers have demonstrated the most effective treatment for pancreatic cancer ever recorded in mouse models, the new treatment completely eliminated tumors in 80 percent of mice across several model types, including those considered the most difficult to treat https://pratt.duke.edu/about/news/radioactive-tumor-implant 37 comments science

- Researchers have engineered a novel type of supercapacitor that remains fully functional even when stretched to eight times its original size. It does not exhibit any wear and tear from being stretched repeatedly and loses only a few percentage points of energy performance after 10,000 cycles. https://pratt.duke.edu/about/news/stretchable-supercapacitors 535 comments science
- Physics explains why time flies as we age - This apparent temporal discrepancy can be blamed on the ever-slowing speed at which images are obtained and processed by the human brain as the body ages. As webs of neurons mature, they degrade, giving more resistance to the flow of electrical signals. https://pratt.duke.edu/about/news/its-spring-already-physics-explains-why-time-flies-we-age 8 comments cogsci
