A cognitive neuroscientist explains that the biological reason the image 'moves' is because the V5 (middle temporal visual area) part of your brain – devoted to motion processing – activates or fires due to the V4 part of your brain – devoted to colour and shape – becomes overstimulated.

In fact, V4 neurons are saturated so much that the resting firing frequency of middle temporal neurons is interpreted as an actual sensory signal. The effect of this illusion strictly depends on several factors, namely on the receptive field sizes (the illusion changes as a function of viewing distance), V4 preference for spirals and spheres, and the middle temporal involvement in 3D and stereopsis. It is a very complex interaction, that rarely lead to suc [ ... ]

One-time use technology or throw-away electronics are becoming increasingly popular with consumers and product manufacturers. Apart from the disposable cameras offered in the 1980s and into the late 90s, tech-based companies could rarely offer such convenience due to the cost of certain parts required. The main reason why companies can now offer inexpensive products, including smartphones and computers, without compromising on modern technology or quality is due to the wide-spread production and availability of transistors – a major component of computers or any microprocessor (shown above).

As the technology gets more expensive the return on investment is even higher - the resulting products outperform, are smaller and less power hungry in each succeeding generation and therefore more valuable to end users.

If you live in North America, you've probably never given the cost of water a second thought. In fact, you've probably taken its value for granted probably because it costs very little or because it's vastly abundant. 

In places like Saudi Arabia, however, a liter of water costs five times as much as a liter of gasoline. This is because much of the water in Saudi Arabia is seawater that is purified in desalinization plants (Al Jubail desalination plant shown above). This price relative to fuel is quite different in the United States. For example, a liter of water (from a tap) is virtually free, while a liter of gasoline is around $0.75 (about $3.00 per gallon). 

As a result of this significant difference in cost, it plays a major effect on hu [ ... ]

The video below shows 16 hours of neural development compressed into 40 seconds of a developing zebrafish's nervous system. Notice how the neurons branch to make connections with other neurons – a process vital to information transmission.

To obtain such accurate footage, the animal's embryo was suspended in water, rather than gel, and its photographers used gentle light sheet technology to capture the specimen in 3D, at a high temporal resolution.
