First robot leg with ‘artificial muscles’ jumps nimbly: Study

While conventional robotic legs are driven by an electromagnetic rotary motor (left), for their musculoskeletal system the researchers use electrohydraulic actuators – i.e. artificial muscles (right). Credit: Thomas Buchner / ETH Zurich and Toshihiko Fukushima / MPI-IS Researchers said on Monday they had designed the first robotic leg with “artificial muscles”—oil-filled bags allowing machines to … Read more

Researcher examines model to foster just and equitable youth engagement in residential facilities

Credit: Unsplash/CC0 Public Domain Recent research by Andrew Nalani, a faculty member at Vanderbilt Peabody College of education and human development, examines the viewpoints of youth care workers in juvenile residential facilities and their desires for fostering more just and equitable systems through youth-adult partnerships. Youth-adult partnerships (Y-APs) are a model for promoting social justice … Read more

Unraveling the fundamental principles of eutectic solidification with real-time, nanoscale imaging

Unraveling the fundamental principles of eutectic solidification with real-time, nanoscale imaging

Credit: Acta Materialia (2024). DOI: 10.1016/j.actamat.2024.120314 During eutectic solidification, a mixture of two or more solids self-assemble, forming composite microstructures ranging from ordered layers to intricate maze-like patterns that underlie properties like tensile strength or ductility. Up to this point, researchers have not understood what conditions drive eutectics to form certain patterns, which is critical … Read more

Scientists prove long-standing wave amplification theory

Scientists prove long-standing wave amplification theory

Equipment used in the Zel’dovich experiment. Credit: University of Southampton Physicists at the University of Southampton have tested and proven a 50-year-old theory for the first time using electro-magnetic waves. They have shown that the energy of waves can be increased by bouncing “twisted waves”—those with angular momentum—off of an object which is rotating in … Read more

Drought sinks longest Polish river to record-low level

Drought sinks longest Polish river to record-low level

This aerial photograph taken on September 6, 2024 shows a view of the drought-affected Vistula River in Warsaw. Poland’s longest river, the Vistula, on Sunday hit a record-low water level in the capital because of drought, the national weather agency said. Its level at one Warsaw measuring station fell to 25 centimeters (10 inches), beating … Read more

New Mo carbide catalysts show high stability and activity in CO₂ conversion

New Mo carbide catalysts show high stability and activity in CO₂ conversion

Abstract image. Credit: DICP Molybdenum (Mo) carbides, known for their unique electronic and structural properties, are considered promising alternatives to noble metal catalysts in heterogeneous catalysis. However, traditional methods for preparing Mo carbides suffer from complex processes, stringent synthesis conditions, challenging crystal regulation, and high energy consumption. Additionally, Mo carbides are susceptible to oxidation and … Read more

How context-specific factors control gene activity

How context-specific factors control gene activity

Credit: Pixabay/CC0 Public Domain Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene regulation; essentially how and when genes are turned on and off to meet the cell’s demands. But … Read more
