Introduction: Acute promyelocytic leukemia (APL) features leukemic cell differentiation arrest at the promyelocytic stage, mainly due to the t (15;17), (q24; q21) translocation that forms the PML-RARA ...

Focusing on the core issue of the multi-scale characteristics and driving mechanisms of spatial differentiation of rural settlements (RS) in the middle-lower Yellow River Basin (ML-YRB), this study ...

Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...

Even a few nights with insufficient sleep promote molecular mechanisms linked to a greater risk of heart problems. This has been shown in a new study in which the researchers investigated how sleep ...

A Yale-led research team has uncovered how a naturally occurring biological mechanism is able to prevent sperm cells from interacting with an egg, preventing fertilization. The discovery, found in ...

The data sets are very large: with more than 75 permanent forest dynamics plots in 29 countries worldwide, the Forest Global Earth Observatory network (ForestGEO) of the Smithsonian Tropical Research ...

The spatial distribution of tree species in species-rich tropical forests is highly complex. The figure shows the spatial position, species identity (color) and size of individual trees in a 500 m × ...

Abstract: Spatial-temporal fusion algorithms commonly encounter difficulties in effectively striking a balance between the extraction of intricate spatial details and changes over time. To mitigate ...
