Carbon Neutral Fuel

We often hear about “carbon footprint“. What does this actually mean? A carbon footprint refers to the amount of carbon dioxide equivalent is being produced for an action or activity. When we refer to carbon neutrality, we’re speaking about ways in which the output of these gasses can be reclaimed to offset the production. Essentially, this means we are offsetting the carbon footprint.

We know that many of the “greenhouse gasses” come from industry, particularly with the burning of fuel. A recent article illustrates one possible way to address this.

The article states:

(Petroleum) was simply ancient algae that had been covered over by shallow seas and then was covered over by silt and dirt,” said Mayfield. “The algae’s proteins and carbohydrates degraded away, leaving the fat, which we call crude oil. So the algae we produce in ponds today makes the same stuff.

So indirectly, this is a roundabout way of harnessing solar energy… but less roundabout than before.

Creating new organs

Rat Kidneys Made in Lab

A recent development in bioengineering has resulted in the production of replacement kidneys that function in rats. This has a great potential for a shortage of organ donations in humans. You can read about this in this article.

About 17,000 people with end-stage kidney disease receive a donor organ each year in the United States, but more than five times as many patients are on waiting lists. In 2011, nearly 5,000 people died while awaiting transplants. Bioengineered kidneys, especially if made using nonhuman sources, could ease or eliminate this organ shortage.

Alien Invasion!

Aliens invade Florida

Here’s an article about an emerging problem involving an invasive species of snails. These snails (Giant African Land Snail) originally come from Africa. They are highly confiscated at airports because they are typically smuggled in for the pet trade. In the wild, they don’t have native predators so they can explode in numbers. They’re pests because they like to devour stucco in buildings for the calcium content since this helps them grow their shells.

I usually have a pretty good way to deal with such pests. However, these snails can carry disease, like rat lungworm that can cause meningitis in humans.
