Protein used during cell development important in cloning technique
Researchers at the University of Minnesota have identified the protein responsible for disassembly of donor nucleoli in the context of nuclear cloning. Although it was already known that nucleoli, essential structures for protein synthesis, normally disassemble or disappear for a period of time in the early animal development and also during nuclear cloning, it was not known until this study what causes this phenomeno
Human intelligence is like a mental juggling act in which the smartest performers use specific brain regions to resist distraction and keep attention focused on critical pieces of information, according to a new brain imaging study from Washington University in St. Louis.
“Some people seem to perform better than others in novel, mentally-demanding situations, but why?” asks Jeremy R. Gray, Ph.D., co-author of the study to be posted Feb. 18 in an advance online issue of the journal Nature N
UI researchers discover new mechanism controlling movement of cell structures
Organelles are compartments and structures inside cells that perform varied and vital functions, including energy production, storage and transportation of important substances and removal of waste products. Normal cellular function requires that organelles be positioned in specific locations in a cell. Thus, movement of the organelles to their appropriate destinations is critical.

Sex and gender scientists explore a revolution in evolution
Darwin may have been wrong about sex. Or at least too narrow minded
At the annual meeting of the American Association for the Advancement of Science, leading researchers and theorists in the evolution of sexual behavior will gather to present the growing evidence that Darwins idea of sexual selection requires sweeping revisions.
I dont have a theory to address it all by any means,
NIAB has patent protection pending for a number of schemes for encoding non-genetic information into DNA. The patent describes four methods by which DNA can be made to hold information in a binary or other number base format as a DNA barcode.
Jonathan White, Head of NIABs Molecular and Genotyping Group said, “The encoding of non-genetic information has the overall major benefit of providing a means of ready identification and authentication of goods and organisms and is particul
Educators and scientists should discard the idea that a cells nucleus is just a bag of chromosomes, according to Johns Hopkins cell biologist Kathy Wilson, Ph.D. In a Feb. 17 session at the annual meeting of the American Association for the Advancement of Science (AAAS) in Denver, Wilson and five others will introduce visual evidence of the nucleuss newly recognized importance.
“The old view is that the nucleus is simply a warehouse for chromosomes,” says Wilson, associate
