UF researcher: Animals think in their own way, but unlike humans
... you ever heard that dolphins are the only species apart from humans that engage in sex for pleasure and not for procreation?" Wynne asked. "I've heard this so many times I always ask, 'So you mean that other animal species know when they're having sex that they're doing it in order to have offspring?'" At...UF study: Barren Siberia, of all places, may be original home to animal life
...split off from and spent differing amounts of time apart from each other, Lieberman said. The analysis also suggests the first trilobite originated on Siberia several million years before the first fossil record of the animals appears. Both studies and methods resulted in the same outcome. "He had trilob...Received truth turned on end in cancer research
... of cancer is that the chromosomes in a cell break apart and then recombine in an incorrect way. At the points of fissure, gene fragments are exposed that can recombine with so-called fusion genes, yielding fusion proteins. Leukemias-blood cancer-normally develop from cells that contain such fusion prote...Functional food Safety aspects

In the opinion of the DFG Senate Commission on Food Safety, it is precisely these safety aspects that have not been adequately cons...Genetic trick adapted from viruses makes gene therapy vectors more versatile
...es. These 2A peptides acted like cleavers to break apart the long protein into the four different, smaller CD3 proteins. The cell used these smaller proteins to build the large TCR:CD3 receptor. In order to replicate inside a cells, the retrovirus RNA must first be changed back into DNA. A retrovirus is a ...UC San Diego bioinformatics experts help reconstruct the genomic makeup of our ancestors

"Intuitively, you can tell apart the temporal bone of a human and the temporal bone of a gorilla, but the beauty for us is that we found that our mathematical formulations were mapping those common-sense intuitive differences in a beautiful, quantitative way."

Three of the cell types couldn't complete the VDJ recombination, and further studies of these cells led to the discovery of major components...Tigers: Big cats need cat food

"When a tumour metastasizes, cells in fact have to decide to leave it and invade other tissues," said Dr. Reed. "Here, in flies, you have cells leaving the tissue, but thei...Search for macular degeneration genes narrows

How the strands of RNA and DNA are pushed apart has a simple physical explanation: the RNA polymerase inserts itself as a wedge between the two, with the RNA trailing out the hole.
