A fish that spits
|
view preview
Besides what we probably have seen while watching The Little Mermaid - fish singing and playing instruments, Finding Nemo, Shark Tale - whale being cleaned at a whale wash! , or even Spongebob Square pants - making hamburgers that is, have you ever seen or heard of a spitting fish? Well, I have not, until today.. Apparently, the archerfish from the family Toxotidea, literally "spit" to catch their prey. It is like a frog, but upgraded, in the sense that it catches insects and land based prey without a weapon, or a physical means. It just teleports its prey from above water, into the water by knocking it out via shooting water droplets. The missile strength of the water droplet is created and altered based on how far and how big their prey is ...

Bipolar Vitamin C

It is extremely essential, that it is your guardian angel in times of stress and need, maintaining your relaxed pain-free state, while keeping your internal pluming up an going.. I like to call it the secondary police of the cell, after the primary cell cycle genes, that is. Not only does it go around making sure all compounds are receiving and exchanging electrons, but it is also among the military forces of the cell. It stands loyal to the cell when it is being invaded. When the cell's economy is no longer stable, mischievous backstabbers- bacteria and viruses or even toxins- love to take action and bring the cell city down, and that happens when there is a lack of electrons circulating, which is when Vitamin C military forces are cut bac ...

Are silent farts worse?
|
view preview
On average, they are, because they tend to contain more sulphur, which is what gives farts their unpleasant smell. Loud farts, on the other hand, tend to contain more nitrogen, hydrogen and carbon dioxide, which are all odourless gases.

How to stand out in Australia
|
view preview
A 2-year-old albino kangaroo has been spotted in Canberra’s Namadgi National Park. Albino kangaroos in the wild usually don’t survive because they stand out and become an easy target for predators. Albino animals also have a genetic predisposition towards sight and hearing issues, making life in the wild almost impossible—but Rene(e), which is always surrounded by its mob, has survived against all odds.

Birds with purple crowns
|
view preview
These beautiful birds are called purple-crowned fairy wrens, endemic to northern Australia. The picture was taken by ornithologists (bird banders) studying the birds as part of population monitoring in Australia. The way they are holding them is called "photographer's grip" which gently secures the legs while keeping the rest of the bird free. Handling time is generally very short.

view preview
A pink Amazon river dolphin on the warm side of the "Meeting of the Waters." This is where the sandy Amazon River meets the dark waters of the Rio Negro in Manaus, Brazil. A strong density gradient contributes to their visible separation, as well as a significant temperature difference - the Amazon flows at around 22°C, while the Rio Negro is around 28°C.

Dental hygiene and the rainforest
|
view preview
Chewing sticks are used by many people instead of toothbrushes. The neem tree grows in many Asian, African, and Middle Eastern countries. Indigenous people in these areas know that chewing neem twigs is good for their teeth. The epidermal tissues contain chemicals that kill bacteria and reduce inflammation. The study of how indigenous (native) plants are used by different cultures is known as ethnobotany.
