You can mend a broken heart this valentine’s day now that researchers invented a new hydrogel that can be used to heal damaged heart tissue and improve cancer treatments. University of Waterloo chemical engineering researcher Dr. Elisabeth Prince teamed up with researchers from the University of Toronto and Duke University to design the synthetic material …
Superior knee and hip replacements are a step closer after Flinders University and Chinese researchers further test and develop a new orthopedic implant coating that has the strong ability to ward off infection — as well as stimulate bone growth. The technology, which has been patented after more promising results just detailed in the lead …
The discovery that football players were unknowingly acquiring permanent brain damage as they racked up head hits throughout their professional careers created a rush to design better head protection. One of these inventions is nanofoam, the material on the inside of football helmets. Thanks to mechanical and aerospace engineering associate professor Baoxing Xu at the …
Image: A biofilm-powered sensor, on the neck, that measures the mechanical signal of swallowing. Credit: Liu et al., 10.1038/s41467-022-32105-6 Researchers at the University of Massachusetts Amherst recently announced that they have figured out how to engineer a biofilm that harvests the energy in evaporation and converts it to electricity. This biofilm, which was announced in …

Adv. 8, eabo6163 (2022) A team of scientists in the Physical Intelligence Department at the Max Planck Institute for Intelligent Systems have combined robotics with biology by equipping E. coli …
Image: Smart skin is a wafer-thin material that reacts simultaneously to force, moisture and temperature with extremely high spatial resolution and emits corresponding electronic signals. Credit: © Lunghammer – TU Graz The “smart skin” developed by Anna Maria Coclite is very similar to human skin. It senses pressure, humidity, and temperature simultaneously and produces electronic …
The combination of nucleic acid nanotechnology and cryo-EM gives unprecedented insights into the structures of large and small RNAs, enabling fundamental advances in RNA biology and drug design We live in a world made and run by RNA, the equally important sibling of the genetic molecule DNA. In fact, evolutionary biologists hypothesize that RNA existed …
