El servidor de preimpresión líder cierra las puertas a la "maldición de IA"
Resumen
La nueva política de arXiv requiere que los autores primerizos obtengan un respaldo de un investigador establecido. Este cambio tiene como objetivo mejorar la calidad y la credibilidad de los preprints científicos presentados.
Área de la Ciencia:
- La comunicación científica es la comunicación científica.
- La publicación académica es la publicación académica.
Sus antecedentes:
- arXiv es un repositorio de acceso abierto ampliamente utilizado para preprints científicos.
- Históricamente, arXiv permitía el envío directo por cualquier usuario.
Objetivo del estudio:
- Informar a los investigadores sobre la nueva política de envío de archivos de arXiv.
- Para explicar la lógica detrás de requerir endosos de autor.
Principales métodos:
- Implementación de políticas por parte de los administradores de arXiv.
- Comunicación de la nueva política a la comunidad científica.
Principales resultados:
- Los carteles por primera vez en arXiv ahora requieren el respaldo de autores establecidos.
- Este cambio de política afecta el proceso de presentación inicial para nuevos investigadores.
Conclusiones:
- El requisito de endoso está destinado a mejorar la integridad de las preimpresiones.
- Esta medida puede racionalizar el proceso de revisión por pares al garantizar una línea de base de credibilidad.

Feedback Inhibition
44.1K
Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Feedback Loops
43.9K
In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.

Imprinting
10.0K
Behavioral imprinting is observed in some newborn animals and occurs when they develop strong and specific attachments to another animal (usually a parent) following brief, early-life exposures. Offspring imprint onto parents within a brief period after birth or hatching; this time window is called the critical period. Once imprinting occurs, the bond established between the parents and their offspring is usually long-lasting.

pre-mRNA Processing
49.0K
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...

Nonsense-mediated mRNA Decay
9.4K
The Upf proteins that carry out nonsense-mediated decay (NMD) are found in all eukaryotic organisms, including humans. Each protein has an individual role, but they need to work in collaboration. Upf1 is an ATP-dependent RNA helicase that unwinds the RNA helix. Because Upf1 can unwind any RNA, Upf2 and Upf3 are required to help Upf1 discriminate between nonsense and normal mRNAs.
Usually, Upf3 binds to an Exon Junction Complex (EJC) at mRNA splice sites. If a ribosome fully translates the mRNA,...
