How Sahara Desert helps the Amazon Rainforest stay green [Video]

English: Sahara desert from space. (Photo credit: Wikipedia)The Sahara Desert is known for its dry and arid regions and the sand dunes that can rise up to almost 600 feet! While this largest hot desert (yes, we have cold deserts too... guess where) can easily be made out from satellites in space, there is more that the satellites have been able to visualise than the dryness of the land.

Watch this short video from NASA below and know how the dryness of Sahara actually helps the Amazon Rainforest stay green.

Balance!



7.5 million wasps under one roof ? [Video]

Wasp (Photo credit: Wikipedia) Can you imagine what it would be to see seven and half million wasps under one roof? Don't worry they are not alive and are well segregated taxonomically. Well, this is what you can expect when you are visiting the American Museum of Natural History (AMNH).

In its recently released episode of Shelf Life, something that we have sharing at Coffee Table Science, since the day it began, the AMNH takes us to its collection of 7.5 million wasps that is still being catalogued, even though it was donated to the museum in the late 1950's. Why, because cataloging takes a lot of time and 7.5 million is a massive number.

Interestingly, the entire collection was donated by Alfred Kinsey's wife, the same Alfred Kinsey who is known for his revelations of human sexuality. If you would like read more about it, here is our post about How Sexology became a Science.

For now, let's get back to the 7.5 million wasps in this Shelf Life Episode.

This 56 year old woman is happy about having a brain stroke [Video]

Every four minutes a person dies in the United States of a stroke! Much like a heart attack, a stroke can happen at any time and to any body, irrespective of their age, sex or standard of living. Strokes occur when blood supply to the brain is affected. This might be due to a a block in the blood vessel or rupturing of the blood vessel, both of which, deprive the brain cells of essential nutrients and more importantly oxygen, and they die. When brain cells die, they take away with them some unique ability they were conferring before the event of the stroke. So, after a stroke, some people lose their control over some muscles, some may forget names, some lose their identity, while most become partially paralyzed. Any which way, stroke is a debilitating condition and usually worsens the quality of life of the person affected and no one can be happy about it.
