No circ. clock for reindeer?
Edyta Zielinska | Mar 10, 2010 | 2 min read
Arctic reindeer, which live most of the year in 24-hour darkness or daylight, may lack an internal clock common to most organisms, according to research published online today (March 11) in __Current Biology.__ ReindeerImage: Per Harald Olsen/WikimediaThe study found no evidence of cyclic changes in reindeer gene expression, consistent with behavioral evidence that the arctic animals do not rely on such daily rhythms. But the fact that the researchers only investigated two clock genes in one

Once believed to be unique to birds and mammals, sleep is found across the metazoan kingdom. Some animals, it seems, can’t live without it, though no one knows exactly why.

Alternative Splicing Goes Mainstream
Sam Jaffe | Dec 14, 2003 | 10 min read
In eukaryotic genetics, the one-gene/one-protein concept has, for the most part, breathed its last. Researchers have rallied behind mechanisms such as alternative splicing, which may allow a lowly 30,000-gene genome to produce the dizzying variety of proteins that some believe is necessary to produce beings as complex as humans. Alternative splicing--the post-transcriptional editing process that can result in various mRNAs--was previously seen as an interesting but relatively uncommon sidesh
