Ultrafast Domain Wall Dynamics in Metallic and Insulating Ferrimagnets - LivestreamA promising approach to encode bits of information for next-generation memory and logic is by using solitons, such as chiral domain walls (DW) or topological skyrmions, which can be translated by currentsacross racetrack-like wire devices. One technological and scientific challenge is to stabilize small spin textures and to move them ...
Many Pleistocene archaeological and paleontological sites beyond the c. 50-thousand-year 14C limit remain poorly constrained in age or undated entirely. Yet, they host key evidence about terrestrial ecosystems, the biological and cultural evolution of H. sapiens, and human geographic range expansion out of Africa. Many such deposits host giant avian ...

Perfect Storm: Climate Change in Asia - LivestreamThe Asia-Pacific region is the world’s most vulnerable region to climate change risks. With its densely populated low-lying territories and high dependence on natural resources and agriculture sectors, Asia is increasingly susceptible to the impacts of rising sea levels and weather extremes. The impacts of climate change encompass multiple socioeconomic ...
