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 phenomenon. Researchers hope the identification of the protein will lead to advances in cloning techniques and potential therapies. The study will be published in the journal Nature Cell Biology on Feb. 17 (www.nature.com/ncb)
“The nucleolus, one of the largest structures found within the cell’s nucleus, contains numerous proteins that have essential roles in cell biology, for cancer, stem cells, and aging,” said lead researcher Nobuaki Kikyo, M.D, Ph.D., assistant professor of medicine, Stem Cell Institute. “By understanding how the nucleolus disassembles and reassembles, we hope to learn more about normal cell development, the roles of specific proteins, and their impact on human diseases.”

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
