A marine animal that looks like you know what
|
view preview
This is Urechis unicinctus, a species of marine spoon worm. It is also know as the fat innkeeper worm or (I bet you'll never guess why) the penis fish. They live in burrows of sand and mud and are commonly eaten raw with salt and sesame oil in Korea and parts of Japan.

What would happen if you didn't get stitches?

I have a big scar on my leg from when I was a kid. I often wonder what would have happened if we let it heal on its own without using stitches. Here's what happens when you do get stitches: Here's what happens without stitches: And finally, this scenario often leads to contamination. In this case, you'd get this: ...

Potential treatment for Down's syndrome?
|
view preview
Down syndrome is caused by a triple copy of chromosome 21, which leads to a number of cognitive and physical delays. Now researchers from the Sanford-Burnham Medical Research Institute in La Jolla, California, have found a protein that restores the some of the cognitive and behavioral disorders found in the disease. Mice who were deficient in the SNX27 protein exhibited similar characteristics to mice with Down syndrome—namely, they had fewer glutamate receptors, which are important for learning and memory, the team reported in Nature Medicine on Sunday (March 24). The researchers also showed that in mice with Down syndrome, the protein is blocked by a molecule encoded on chromosome 21, and produced in excess in Down syndrome mice as a re ...

The kiwi bird
|
view preview
The kiwi is a flightless bird found only in New Zealand. They're around the size of a chicken, and lay the largest eggs in relation to their body size of any bird in the world. Their eggs can be up to 20% of the females body weight - the equivalent of a 130 pound woman giving birth to a 26 pound baby. ...

Termites are nature's architects
|
view preview
Termites are pretty astonishing creatures by anyone's standards -- their queens are thirty times the size of soldiers and they produce an amazing thirty eggs per minute. Relative to their size, termites build the largest structures in the animal kingdom. Their towers can reach an incredible 25ft (7.6m) high and 40ft across (12.1m) - and that's just above the ground! They can burrow as far as 225ft (68m) below the surface.

The mammoth of birds
|
view preview
This bird, known as the elephant bird, went extinct sometime in the 17th century as a result of human activity. Although flightless, the birds were widespread, inhabiting the northern to the southern tip of Madagascar. Not only are they three times the size of an ostrich, they are also known for their massive egg. These fossils are so rare that one is currently being auctioned and is expecting to go for an upwards cost of $40 000..

What causes the brown staining of some childrens teeth?
|
view preview
The brownish staining of a child's tooth enamel is due to excessive ingestion of fluoride. Fluoride is a mineral compound that is useful in preventing dental caries. It is thought to work by strengthening the mineral composition of tooth enamel making it more resistant to acid attacks. It may also reduce the acid-producing ability of microorganisms in dental plaque. The water supply may naturally provide fluoride, or it may be added. Mild fluorosis causes white mottling of the teeth; severe cases show brown staining and usually occur in areas where the level of fluoride in the water is many times greater than the recommended level of 0.7 to 1.2 parts per million. ...

Peanut the turtle
|
view preview
This is Peanut the turtle, shortly after being found in Missouri in 1993. She was taken to to a zoo in St. Louis where the six-pack ring was removed. It seems that she was trapped in the plastic ring as a young turtle and was unable to free herself. Subsequently, her shell moulded itself to the plastic ring and she grew in the strange shape you see here. Unfortunately the damage is permanent, but peanut is expected to live a long life and today she serves as a mascot for the fight against beach littering. Please, always remember to clean up after yourself at the beach. ...

A Genetically Modified World...?
|
view preview
Genetic modification is one of the most controversial topics in all of modern science and with the advancement of synthetic biology over the last decade or so it is sure to become even more of a talking point in the future. Genetic modification is a subject that most people seem to have an opinion on, but I must say that a great deal of those opinions are built upon misconceptions or influenced by the charm of organic propaganda. I cant help but find such misunderstandings quite ironic, for example, the man who strongly opposes the consumption of genetically modified foods, yet requires the injection of insulin produced via genetically modified micro-organisms to keep his diabetes under control, to name just one such example. It seems that ...

Look at this larva that resembles an adult snake
|
view preview
This is the larva of the Hemeroplanes triptolemus moth. In its larval form it is capable of expanding its anterior body segments to give it the appearance of a snake, complete with simulated eyes. It's mimicry extends even to the point where it will harmlessly strike at potential predators.
