New electron microscopy technique reveals complex spin structures at femtosecond timescales
Plasmons are collective oscillations of electrons in a solid and are important for a wide range of applications, such as sensing, catalysis, and light harvesting. Plasmonic waves that travel along the surface of a metal, called surface plasmon polari.....»»
Climate patterns from cave mineral deposits linked to Chinese dynasty collapses
China's dynastic history spans 13 periods of rule from 2070 BC until the last emperor abdicated in 1912. While factors leading to the transitions between dynasties are a complex mixture of environmental, social and economic issues, the role of climat.....»»
Hybrid model links micro and macro scales in complex systems
In fields ranging from immunology and ecology to economics and thermodynamics, multi-scale complex systems are ubiquitous. They are also notoriously difficult to model. Conventional approaches take either a bottom-up or top-down approach. But in dist.....»»
Analysis provides new insights into the replication of BK polyomavirus, a major cause of kidney transplant failure
BK polyomavirus, or BKPyV, is a major cause of kidney transplant failure. There are no effective drugs to treat BKPyV. Research at the University of Alabama at Birmingham reveals new aspects of BKPyV replication, offering possible drug targets to pro.....»»
Critical reporting weakens the effect of "sportswashing" for authoritarian regimes, experiment reveals
Major sporting events offer authoritarian regimes the opportunity to present themselves to the population of foreign states as progressive and open. However, this positive effect on image—or "sportswashing" for short—only works in other states wh.....»»
Interdisciplinary research reveals impressive adaptation mechanisms of microscopic algae
Researchers from the University of Jena and the Leibniz Institutes in Jena have published new findings on the adaptability of the microalgae Chlamydomonas reinhardtii. The interdisciplinary study, largely carried out by scientists from the Cluster of.....»»
