Metagenomics of the deep Mediterranean Sep 19, 2007
Now, some of the genes detected have been positively identified as luxA, directly involved in bioluminescence. Why would deep sea bacteria be luminescent" One possible explanation is that they become attractive to animals that at these depths are very photosensitive. Being swallowed by one of these creatures would give the bacteria a temporary oasis of nutrient-rich conditions before another long dip in the abyssal black. ### Dr Rodriguez-Valeras paper, entitled, Metagenomics of the Deep...

Giant luminescent squid captured on film for first time Feb 15, 2007
The footage, according to the research paper, shows the squid's attacking behaviour and bioluminescence (propensity to emit light) which suggests that the cephalopod is far from the sluggish, inactive creature it was previously suspected of being. Kubodera and his team note that the squid swims both forwards and backwards by flapping its large triangular fins and changes direction quickly by bending its flexible body. (Ninemsn)

Early To Bed, Early To Rise: Genetics Of The Morning Lark Sep 21, 2006
They identified 21 sites, one of which (Serine 659), was implicated in FASPS. By monitoring the bioluminescence cycles of cell lines, the researchers demonstrated that mutation of Serine 659 causes a shortening of the luminescence period and recapitulates the FASPS phenotype. The researchers determined that the mutated form of Serine 659, which does not get phosphorylated, leads to PER2's destabilization and earlier clearance from the cell nucleus. (Science Daily)
