Research in the use of organic polymers as the active semiconductors in light-emitting
diodes has advanced rapidly, and prototype devices now meet realistic specifications for …

Over the past decade, there have been an increasing number of studies on the association
between vitamin D deficiency and anthropometric state. However, we did not identify any …

In the era of global industrialisation, the exploration of natural resources has served as a
source of experimentation for science and advanced technologies, giving rise to the …

Correlated quantum-chemical calculations are used to investigate the influence of interchain
interactions on the absorption and emission of π-conjugated chains. The results are …

The largest monkeypox virus (MPXV) outbreak described so far in non-endemic countries
was identified in May 2022 (refs. ). In this study, shotgun metagenomics allowed the rapid …

Plant microRNAs have been implicated in various abiotic stress responses. We identified
several conserved microRNAs that showed differential expression in Medicago truncatula …

The yellow fever virus (YFV) epidemic in Brazil is the largest in decades. The recent discovery
of YFV in Brazilian Aedes species mosquitos highlights a need to monitor the risk of …

Background A city-wide sanitation intervention was started in Salvador, Brazil, in 1997 to
improve sewerage coverage from 26% of households to 80%. Our aim was to investigate the …

Background The loss of skeletal muscle mass (MM) or muscle function (MF) alone increases
the risk for losing physical independence in older adults. We aimed to examine the …

When an exciton approaches the interface between two conjugated polymers, either energy
or charge transfer can take place. We present a detailed experimental investigation of these …
