Researchers have discovered that atomic vibrations can modulate the macroscopic electric polarization of ferroelectric materials. The study uses ultrafast x-ray diffraction to track charge dynamics and link them to macroscopic properties, paving the way for high-speed electronics.
High-ranking mothers' cubs have lower CDV infection probability and reduced mortality, while high-ranking adults are more likely to be infected but experience similar mortality rates. The study highlights the impact of social status on immune processes and disease transmission in a wildlife population.
Physicists develop new method to precisely characterise extremely short light pulses, allowing for detailed information about electron place of origin in novel materials. This enables study of superconductors and topological materials, crucial for quantum computing and energy-efficient processors.
Researchers found that non-selective ion channels, like the NaK channel, have a selectivity filter with sizeable dynamics, unlike selective channels. The study revealed two different forms of the selectivity filter, one for each ion type, which explains why the NaK channel can pass both sodium and potassium ions.
The vampire bat's unique blood-based diet requires specific genetic and microbial adaptations, including enhanced iron assimilation and immunity, to tackle nutritional and non-nutritional challenges posed by blood meals. The findings suggest that the bats' microbiome plays a crucial role in their defense against viral infections.
Microplastics in soils and freshwaters can have damaging effects on ecosystems, triggering adverse reactions in organisms and potentially disrupting hormone systems. Humans also ingest microplastics through food, highlighting the need for reliable data on microplastic degradation and effects.
Researchers discover mechanism responsible for limit on indium content in InGaN thin films, affecting blue light emitting diodes. A regular pattern of atoms within the monolayer limits indium concentration to 25-30%.
The study reveals that water molecules at the RNA surface perform tipping motions, known as librations, which influence the structure and dynamics of RNA. The findings show a complex scenario where water fluctuations are transferred to RNA vibrations, essential for avoiding local overheating.
Researchers have elucidated the ultrafast motions and structural characteristics of protons in water under ambient conditions, identifying the Zundel cation as a predominant species. The proton explores all locations between two water molecules within less than 100 fs, losing memory quickly due to strong electric field fluctuations.
