Today, bioluminescence fromAliivibrio fischeriisused to monitor water toxicity. When exposed to pollutants, light output from the bacterial culture decreases, signalling the possible presence of a contaminant. Bioluminescence has even played a part in warfare. Bioluminescent organismsaided in the sinkingof...
Each fringe can be smaller than one wavelength of the light used to create them. Decoding these interference fringes requires a key — that key is the right kind of light. Next, we'll explore exactly how light makes interference fringes. Holograms and Light Light reflection can be specular,...
so it makes bioluminescence, like fireflies make light. We're not doing anything to the cells here, we just took the picture by turning the lights off in the room, and this is what we see. 00:00 And what's actually interesting to us was not that the bacteria made light but...
While we used to think they were pretty rare, we're now seeing them caught more often in nets and the like, as well as hearing reports of them washing up on beaches. The actual range of the giant oarfish is pretty wide. They're known to be in the Atlantic (and the Mediterranean ...
Second, we performed a sensitivity analysis to determine how the choice of criterion used to define long versus short gonopodia and high versus low sexual dimorphism index standard length influenced these models. Further details can be found in Supplementary Note 3 (Supplementary Tables 6–8, ...

a lot of people actually thought it was bioluminescence initially. the difference is you can see it during the day, and usually bioluminescence isn't bright enough to be seen during the day. this is based fully on structure within the tissue, whereas bioluminescence is a chemical reaction that...
Calcium is among the most commonly used ions, in a multitude of biological functions, so much so that it is impossible to imagine life without calcium. In
bioluminescence tests check for the presence of living cell organisms, such as staphylococcus aureus , on surface preparation or distribution areas. The presence of biological material can indicate that these surfaces are contaminated and require thorough disinfection. ATP testing checks the aerobic colony...
For example, hidden blood spatter patterns can help investigators locate the point of attack and even what sort of weapon was used (a bullet makes blood splatter very differently than a knife does). Luminol may also reveal faint bloody shoe prints, which gives investigators valuable information ...
