Fun Facts

Recommended Posts

Biologists have long known that bones glow under ultraviolet (UV) light, but the researchers were astonished to learn that chameleons could harness this characteristic to display visible fluorescent patterns through their skin, study co-author Frank Glaw, a herpetology curator at the Bavarian State Collection of Zoology (ZSM) in Munich, Germany, said in a statement.

"That animals use this phenomenon to fluoresce themselves has surprised us and was previously completely unknown," Glaw said.

Fluorescence, in which special structures glow in the presence of light, differs from bioluminescence, a process that describes light generated by a chemical reaction between compounds in an animal's body. Fireflies, some types of fungi and numerous deep-sea creatures are bioluminescent, while fluorescent animals include scorpionscoralsjellyfish, a rare type of sea turtle, and now, chameleons.

The study's authors looked at 160 specimens representing 31 species in the Calumna genus, a group of chameleons native to Madagascar, and 165 specimens from 20 species of the Furcifer genus, found in Madagascar and parts of Africa. They photographed living animals in their habitats as well as preserved specimens, using UV light to illuminate the chameleons and reveal their glowing patterns.

Next, they turned to micro-computed tomography — 3D X-ray imaging on the microscopic level — to literally connect the dots, matching the glowing spots in the patterns to raised bumps in the lizards' bones known as tubercles, which provided the source of the glow.

In the brown leaf chameleon (<i>Brookesia superciliaris</i>), tubercles on its skeleton generate glowing patterns of dots that are visible through its skin.

Nearly all the species revealed previously unseen blue patterns on their skin when under UV light, the researchers discovered. Most of the lizards displayed patterning on their heads, but some showed fluorescent markings across their bodies, the study's first author David Prötzel, a ZSM doctoral student, said in the statement. The patterns appeared blue because the lizards' thin outer layer of skin serves as a filter, nudging the fluorescence toward the blue end of the spectrum, according to the study.

The thin skin stretched over the bumps serves as a window, allowing UV light to reach the bone and then enabling the shine to reflect through the skin. In shadowy, humid forest habitats, intermittently-visible fluorescent patterns could allow the lizards to signal each other without drawing the attention of predators, the study authors wrote.

Patterns tended to cluster around the chameleons' eyes and the front of their heads, areas known to be important for communication between individuals. On average, male specimens across species displayed more patterning than females; while it is still uncertain how the chameleons may use fluorescence, this male-skew suggests it may play a role in sexual selection, though further study will be required to say for sure, the scientists explained.

"Fluorescence in terrestrial vertebrates has been underestimated until now, and its role in the evolution of ornamentation remains largely unexplored, but this is a promising avenue for future research," the study authors reported.

The findings were published online Jan. 15 in the journal Scientific Reports.

The first post was interesting. 

I do not want anything political/racial in nature on our forum.

We're a gaming clan forum not a political discussion board.

If I may make note of one thing in today's news... 3 political prisoners are released by the government of N.Korea ahead of historic peace talks featuring de-nuclearizing and reuniting Korea after a 60 year war seemingly about to result in nuclear confrontation. I, if not the Nobel committee would like to congratulate our deplorable President Donald J. Trump for a dazzling foriegn policy success and a boon to the future of Mankind.

However it is political in nature (June 12th if I get what you are hinting at, a meeting between politicians)

 

 I really don't want a gaming clan forum to become an outlet for politics. As I have stated before.

You can treat mosquito bites by applying hot spoons on bites as it breaks up the venom.  It usually takes a couple applications.  You can heat spoons in boiled water and cool slightly but it won't work unless its very hot.

Sound like that could hurt of they stayed in the boiling water too long.  :shock:

It does not feel pleasant.  Also it might not work if your bites are from something else like a spider.  You fan the spoon a couple times and it cools it. 

 

...You can pour boiling water into a glass cup without cracking it only if there's a metal spoon in the cup, because it absorbs heat
