• What can the water monster teach us about tissue regeneration in humans?
  

  Based on two new studies by researchers at the Salk Institute for Biological Studies, regeneration of a new limb or organ in a human will be much more difficult than the mad scientist and supervillain, Dr. Curt Connors, made it seem in the Amazing Spider-man comics and films.As those who saw the rec more

• Mobile DNA Elements Can Disrupt Gene Expression And Cause Biological Variation, Study Shows

  The many short pieces of mobile DNA that exist in the genome can contribute to significant biological differences between lineages of mice, according to a new study led by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Res more

• Cornell Chronicle: NSF plant genome program awards

  A team of Cornell researchers will develop a tool to knock out genes in maize and another team will sequence wild rice genes, identify their functions and insert key genes into cultivated lines for breeders, thanks to multimillion-dollar grants from the National Science Foundation (NSF).

• CHH islands: de novo DNA methylation in near-gene chromatin regulation in maize [RESEARCH]

  Small RNA-mediated regulation of chromatin structure is an important means of suppressing unwanted genetic activity in diverse plants, fungi, and animals. In plants specifically, 24-nt siRNAs direct de novo methylation to repetitive DNA, both foreign and endogenous, in a process known as RNA-direct more

• HP1a, Su(var)3-9, SETDB1 and POF stimulate or repress gene expression depending on genomic position, gene length and expression pattern in Drosophila melanogaster

  Heterochromatin protein 1a (HP1a) is a chromatin-associated protein important for the formation and maintenance of heterochromatin. In Drosophila, the two histone methyltransferases SETDB1 and Su(var)3-9 mediate H3K9 methylation marks that initiates the establishment and spreading of HP1a-enriched more
