Luminescence Developments Help Scientists See The Light
James Kling | May 11, 1997 | 9 min read
Biologists are constantly seeking more sensitive assays to detect the presence of organisms or telltale DNA, RNA, and proteins. Although radioactive tags incorporated into the target itself (or into a complementary strand)-and later detected by Geiger counters or film exposures-have traditionally given good sensitivity, the problems of waste disposal and laboratory monitoring have driven a search for alternative tags that have radioactivity's sensitivity but avoid its hazards. Fluorescent tags-

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
