Article Synopsis
- - The study examines the relationship between tree maturation size and reproduction, finding that larger tree species tend to start reproducing at a smaller size than expected, challenging previous assumptions.
- - Researchers analyzed seed production data from 486 tree species across different climates, revealing that maturation size increases with maximum size but not in a straightforward manner.
- - The results indicate that this trend is particularly pronounced in colder climates, highlighting the importance of understanding maturation size to better predict how forests will respond to climate change and disturbances.
Article Synopsis
- - Small nucleolar RNAs (snoRNAs) are non-coding RNAs crucial for the creation of ribosomes and spliceosomes by targeting specific sites on ribosomal and spliceosomal RNAs for modifications, though many snoRNAs still lack comprehensively identified functions.
- - An enhanced method called chimeric eCLIP was developed to investigate snoRNA-target RNA interactions, confirming known interactions in cell lines and discovering new ones, particularly for orphan snoRNAs.
- - The study found that snoRNA complexes with certain accessory proteins, such as WDR43 and NOLC1, have unique interactions that influence ribosome and spliceosome biogenesis, highlighting the dual role of snoRNAs in modifying RNA and regulating splicing processes.
Recent climate change should result in expansion of species to northern or high elevation range margins, and contraction at southern and low elevation margins in the northern hemisphere, because of local extirpations or range shifts or both. We combined museum occurrence records from both the continental U.S.

This phenomenon, known as genomic imprinting, results in genes preferentially transcribed from one parental allele. While local epigenetic factors such as DNA methylation are known to be important for the establishment of imprinted gene expression, less is known about the mechanisms by which differentially methylated regions (DMRs) lead to differences in allelic expression across broad stretches of chromatin.

A high-throughput array receiver has been developed that enables communication in radio frequency interference-rich environments with field programmable gate array (FPGA)-based frequency channelization and packetization. In this study, a real-time interference mitigation algorithm was implemented on graphics processing units (GPUs) contained in the data pipeline.
