Citric acid: a natural preservative?
|
view preview
If you are into purchasing organic foods, you are likely the type of person who reads the ingredients label of everything you buy. A common food ingredient found in organic foods is citric acid. The name of the chemical reminds us of citrusy fruits, but have you ever questioned why it is used, where it comes from, or how it is produced? Or do you simply trust the ingredients of products labelled 'organic'? Most consumers will assume that citric acid is naturally extracted from fruit sources, such as lemons and limes, and used as a "natural" alternative to chemical preservatives, but that's far from the truth. The citric acid found in jarred foods and beverages is typically manufactured in factories using a species of black mold called Asperg ...

Camel spiders!
|
view preview
Solifuges are a variety of arachnids found in deserts. While they are called Camel Spiders, they belong to a different order from true spiders. It may appear terrifying. However, it seems the internet blows its fear factor out of proportion. After a few photos circulated around the internet, outlandish claims about their astounding physical abilities and voracious appetite for human flesh arose. No. They cannot run at 30 mph. (They do run at 10 mph, which is still incredibly fast.) They cannot kill humans, although they have a painful, albeit non-venomous bite. They can only grow to about 6 inches. They do not subsist on a diet of camel stomachs. Solifuges are content with eating insects, small reptiles, birds and rodents. ...

Bonobos, Chimpanzees, and the 98% DNA Link
|
view preview
When it comes to the animal kingdom, we often find ourselves marveling at the diversity of species that inhabit our planet. Regardless of our differences, the more we delve into the intricacies of genetics and biology, the more we realize just how interconnected all life on Earth truly is. One remarkable example of this interconnectedness is the relationship between humans, bonobos, and chimpanzees. Despite the differences in their "personality" traits, our DNA tells a compelling story of our shared ancestry with these incredible primates. Bonobos and chimpanzees, our closest living relatives in the animal kingdom, are often viewed as two sides of the same evolutionary coin. While they share approximately 98 percent of their DNA with each ot ...

Before the iPhone and before the iPad, there was the Newton
|
view preview
The MessagePad, released in 1993, was the first in a series of Newton devices to be developed and sold on the market. The 1.4 pound physical device was collaboratively manufactured by Apple and Sharp. The MessagePad packed a 20MHz ARM 610 RISC processor, 640 kilobytes of RAM, and a 336x240 monochrome LCD touch screen with stylus and handwriting recognition support. It was powered by four AAA batteries. It ran Newton OS version 1.05 and cost $699.99. The Newton platform was axed from the Apple product line for two main reasons. (1) The early Newton OS that shipped with the original MessagePad proved to be not so user friendly, especially when it came to the unpredictable handwriting recognition software. The press and other media outlets (inc ...

Albert Einstein in colour!
|
view preview
This is a colourised photograph of Albert Einstein taken during a lecture in Vienna, Austria, in 1921. To create colourised images, digital artists take a black and white or sepia photograph and use historical references to work out which colours should go where. This photo was originally taken by Ferdinand Schmutzer and coloured by Dana Keller from History in Color.

Abortion is a tough lemon to swallow

view preview
Take a good look at this premature child. It's hard to deny that it isn't a fully formed human being, though in some parts of the world, abortions at the second and third trimester are perfectly legal  Thoughts are welcome.
