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 ...

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.

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).


A transistor is simply an on/off switch made ...

Most universities allow students to use university network printers in student labs when they are working on the university network as part of their tuition or computer use or technology fees charged to students when they register for classes. The average school spends several thousand dollars per month for this service. This service is expensive because students print personal jobs unrelated to academics, such as downloads from entertainment Web sites and photos of friends and family. 

Winthrop University in South Carolina decided to charge students a $10 printing fee that allows them to print 250 pages per semester on University network printers. After that, the students are charged $0.04 for each additional page that they print. As a resu ...
