To understand how heat normally flows, you could study the second law of thermodynamics – or wrap your hands around a hot mug of coffee. Both tell us that heat tends to flow toward cooler regions. As a material’s thermal energy increases, its atoms vibrate, and quantum mechanics describes these vibrations as phonons: quasiparticles that transport heat. Normally, collisions between phonons cause heat to dissipate slowly. But in highly ordered, pure crystals, these collisions can result in a fluid-like, directional heat flow known as phonon hydrodynamics. Researchers from the group of Theory and Simulation of Materials, led ...

New research confirms Arctic peatlands are expanding as temperatures continue to rise.  The Arctic is warming faster than the rest of the planet, with average temperatures increasing by about 4°C in the last four decades.  The new study, led by the University of Exeter, shows peatlands have expanded since 1950, with some peatland edges moving by more than a metre a year.  Given that the study covered a broad range of Arctic conditions – ...

Environmental pollutant analysis typically requires complex sample pretreatment steps such as filtration, separation, and preconcentration. When solid materials such as sand, soil, or food residues are present in water samples, analytical accuracy often decreases, and filtration can unintentionally remove trace-level target pollutants along with the solids. To address this challenge, a joint research team led by Dr. Ju Hyeon Kim at the Korea Research Institute of Chemical Technology (KRICT), in collaboration with Professor Jae Bem You’s group at Chungnam National University, has developed a microfluidic-based analytical device that enables direct ...

Summary When AI powered prosthetic arms that move autonomously become widespread, understanding how people feel about them and accept them will be crucial. In this study, we used virtual reality to simulate a situation in which a participant’s own arm was replaced by a robotic prosthetic arm, and examined how the prosthesis movement speed affects embodiment, including body ownership, the sense of agency, usability, and social impressions of the robot such as competence and discomfort. We found that both overly fast and overly slow movements reduced body ownership and usability, whereas a moderate speed close to natural human reaching, with a movement duration of about ...

Kyoto, Japan -- Cell and gene therapies, or CGT, have come a long way since they were first introduced.

In 2016 while hiking on a hillside in Morocco, geologist Rowan Martindale saw something that made her stop in her tracks: a slab of sedimentary rock covered in a wrinkly texture reminiscent of elephant skin.  “I looked at the wrinkles and I was like, ‘These aren’t supposed to be in rocks like this. What the heck is going on?’” said Martindale, an associate professor at The University of Texas at Austin’s Jackson School of Geosciences. Rock textures hold clues about the geological activity that shaped them. To Martindale, these wrinkles in time were a textbook example of microbial mat fossils. They captured a teeming ...
