Attention paleo dieters
|
view preview
A new study suggests that humans who live in industrialized societies don’t have the guts to stomach a real hunter-gatherer diet. Compared with hunter-gatherers, industrialized peoples’ intestines have fewer kinds of microbes - and are missing at least one major group of ancient bacteria.

Bringing the wholly mammoth back to life
|
view preview
Before you get any ideas that we're cloning wholly mammoths back into the 21st century, it's not that. An American geneticist has extracted DNA from the frozen remains of a long-dead mammoth found on Wrangel Island in the Arctic Ocean (shown above), created a synthetic replica of it, and implanted it into elephant cells that have been isolated in a petri dish, using a new technique of DNA splicing that allows for unprecedented accuracy. The technique used to join synthetic mammoth DNA fragments with the genetic code of an elephant is called CRISPR/Cas9, and while it’s been recently used to create transgenic organisms, this is the first time it’s been used on the DNA of an extinct organism. Way to go! Source: http://www.sciencealert.com/mammot ...

Can plastic be converted back to oil?
|
view preview
Start by watching the video below In the video, a Japanese man converts plastic waste into usable oil and fuel using a machine that thermochemically decomposes the plastic in a process known as pyrolysis. Pyrolysis works by thermochemically breaking down material at temperatures above 350 degrees Celsius in the absence of water. This not only physically melts down an object, but also changes its chemical composition so that, in the case of plastic waste, it reverts back into boiling liquid and eventually gas.

Lithops are succulents that have evolved to avoid being eaten by animals by blending in with pebbles and stones. In botany, succulent plants, are plants having some parts that are more than normally thickened and fleshy, usually to retain water in arid climates or soil conditions. Succulent plants may store water in various structures, such as leaves and stems. ...

Did you know underwater cables power the internet?
|
view preview
I didn't lol Hundreds of thousands of kilometres of submarine cables lye on the ocean floor - sometimes at depths nearing 8,000 metres. These cables are essential for powering the modern Internet, transmitting 99 percent of all international data. The Submarine Cable Map is a free resource from TeleGeography. Data contained in this map is drawn from the Global Bandwidth Research Service and is updated on a regular basis. ...
