Despite the global importance and extraordinary diversity of soils, they have been notoriously challenging to study.
One reason memory has proven challenging to study, Dr. Aronov argues, is in part tied to how it is investigated.
Similar behavior occurs inside of supersonic combustors (scramjets) under startup conditions, but it is challenging to study these conditions experimentally.
Synthetic biologists have engineered living, communicating cells to form cellular patterns1,2 and synchronize gene expression3 but living systems are inherently challenging to study and engineer.
The organized flight of birds is one of the most easily observed, yet challenging to study, phenomena in biology.
Early steps in spliceosome assembly are challenging to study biochemically and structurally due to compositional and conformational dynamics.
Conclusion: Our results highlight the importance of analyzing narrative notes to understand the scope of conditions such as insomnia that are challenging to study using structured variables alone.
"It is challenging to study these types of questions because systematic data on return migrants are not typically collected," Abramitzky said.
Historically, it has been challenging to study the broad range of base modifications because very few are amenable to molecular biology techniques, especially sequencing.
Soil organic matter is central to agriculture, carbon cycling, and contaminant sequestration, but due to its extreme heterogeneity it is challenging to study with most modern analytical approaches.
Zoonotic diseases are challenging to study from the ecological point of view as, broadly speaking, datasets tend to be either detailed on a small spatial extent, or coarse on a large spatial extent.
