Mussels survive by sticking to rocks in the fierce waves or tides underwater. Materials mimicking this underwater adhesion are widely used for skin or bone adhesion, for modifying the surface of a scaffold, or even in drug or cell delivery systems. However, these materials have not entirely imitated the capabilities of mussels.
A joint research team from POSTECH and Kangwon National University (KNU) - led by Professor Hyung Joon Cha and Ph.D. candidate Mincheol Shin of the Department of Chemical Engineering at POSTECH with Professor Young Mee Jeong and Dr. Yeonju Park of the Department of Chemistry at KNU - has analyzed Dopa and lysine, which are the amino acids that make up the surface adhesive proteins secreted by mussels, and verified that their roles are related to their location. The team has taken a step closer to revealing the secret of underwater adhesion by uncovering that these amino acids can contribute to surface adhesion and cohesion differently dependi

YouTube is a treasure trove of virtual reality fails: users tripping, colliding into walls and smacking inanimate and animate objects. By investigating these VR Fails on YouTube, researchers at the University of Copenhagen have sought to learn more about when and why things go sideways for users and how to improve VR design and experiences so as to avoid accidents.
Millions of YouTube viewers have enjoyed hearty laughs watching others getting hurt using virtual reality - people wearing VR headsets, falling, screaming, crashing into walls and TV sets, or knocking spectators to the floor. Some of us have even been that failing someone. Now, videos of virtual reality mishaps, called VR Fails , have actually become a field of research.
An interdisciplinary research team from TU Dresden at the Chair of Network Dynamics headed by Prof. Marc Timme (Center for Advancing Electronics Dresden - cfaed & Institute of Theoretical Physics) has studied people s motivation to use shared mobility offers.
In the modern day, our interactions with voice-based devices and services continue to increase. In this light, researchers at Tokyo Institute of Technology and RIKEN, Japan, have performed a meta-synthesis to understand how we perceive and interact with the voice (and the body) of various machines. Their findings have generated insights into human preferences, and can be used by engineers and designers to develop future vocal technologies.
Panayiotis Panos Diplas, P.C. Rossin Professor of Water Resources Engineering in Lehigh University s P.C. Rossin College of Engineering and Applied Science, has been named as the recipient of the 2021 Hunter Rouse Hydraulic Engineering Award. The award is presented annually by the Environmental and Water Resources Institute (EWRI) of the American Society of Civil Engineers (ASCE) to honor an individual who has made outstanding contributions to hydraulics and waterways.
