Tech Xplore / Microrobots overcome navigational limitations with the help of 'artificial spacetimes'

Microrobots—tiny robots less than a millimeter in size—are useful in a variety of applications that require tasks to be completed at scales far too small for other tools, such as targeted drug-delivery or micro-manufacturing. ...

Phys.org / Surface-only superconductor is the strangest of its kind

Something strange goes on inside the material platinum-bismuth-two (PtBi₂). A new study by researchers at IFW Dresden and the Cluster of Excellence ct.qmat demonstrates that while PtBi₂ may look like a typical shiny gray ...

Phys.org / Heat-resistant kelp cultivars for warmer seas: A novel triploid breeding method

Kelp species such as Saccharina japonica and Undaria pinnatifida serve as critical global economic resources. However, global warming, marked by rising seawater temperatures, is severely impacting kelp cultivation. This reality ...

Medical Xpress / Pause and rewind: How the brain keeps time to control action

Whether speaking or swinging a bat, precise and adaptable timing of movement is essential for everyday behavior. Although we do not have sensory organs like eyes or a nose to sense time, we can keep time and control the timing ...

Phys.org / Using AI to predict earthquakes: Machine learning detects subtle changes before lab-scale fault failures

Predicting earthquakes has long been an unattainable fantasy. Factors like odd animal behaviors that have historically been thought to forebode earthquakes are not supported by empirical evidence. As these factors often occur ...

Medical Xpress / A 'magic bullet' for polycystic kidney disease in the making

Polycystic kidney disease (PKD) is a debilitating hereditary condition in which fluid-filled sacs form and proliferate in the kidneys. Over time, the painful, growing cysts rob the organs of their function, often leading ...

Phys.org / Central America's 'five great forests' are lifelines for North America's migratory birds

Every spring, the familiar songs of Wood Thrushes and warblers return to the parks and backyards of eastern North America. But their journey begins far to the south—in the lush, remote forests of Central America that sustain ...

Phys.org / Extending the lifespan of electrocatalysts via continuous chromium dissolution

Although chromium itself is not an active element, its continuous dissolution enables a reversible surface transformation that keeps the Co-Cr spinel oxide electrocatalyst active and stable. This could significantly improve ...
