VLF Space Barrier

NASA scientists have discovered an energy barrier around the earth that protects us from radiation and that is accidentally man made. The barrier is made of VLF (very low frequency) radio waves, which are generally used to communication with underwater submarines but have been leaking into the atmosphere.

Space Spiders

Someone decided that it was a good idea to put spiders on the International Space Station! Experiments with the space spiders (!) have shown that the spiders need a point of reference when building their webs and that light can be used as that reference in the absence of gravity. With no point of reference the spiders spin symmetrical webs in zero-g.

Effective Reading

I came across two great guides on effective reading this week, a detailed guide from Maarten Van Doorn and a more digestible guide from Denys Zhadanov. Both posts overlap on some great techniques on how to read with purpose, take notes, and recall and synthesis those notes into long term knowledge.

Fish Farmers

Researchers at Griffith & Deaking universities have found proof that longfin damselfish have domesticated mysid shrimp. These damselfish farm algae for food, and use the mysid shrimp feces as fertilizer. They even protect the shrimp from other fish outside the farm that try to eat the shrimp.

Using prefers-reduced-data

The Polypane blog posted a great how to article on using the new prefers-reduced-data media query when creating websites. Support for the new prefers-reduced-data is on the way in browsers, and it let web developers specify lower size resources and omre efficient methods of operation for users with lower bandwidths.
