And here they are:

Thermoception:  Ability to sense heat and cold. Thermoceptors in the brain are used for monitoring internal body temperature.

Proprioception: The sense of where your body parts are located relevant to each other. 

Chronoception: Sense of the passing of time. Your body has an internal clock. 

Equilibrioception:  The sense that allows you to keep your balance and sense body movement in terms of acceleration and directional changes. 

Magentoception:  This is the ability to detect magnetic fields. Unlike most birds, humans do not have a strong magentoception, however, experiments have demonstrated that we do tend to have some sense of magnetic fields. 

Tension Sensors:  These are found in such places as your muscles and allow the brain the ability to monitor muscle tension.

Nociception:  In a word, pain.  This was once thought to simply be the result of overloading other senses, such as “touch”, but it has it’s own unique sensory system.  There are three distinct types of pain receptors: cutaneous (skin), somatic (bones and joints), and visceral (body organs).

Given Tablets but No Teachers, Ethiopian Children Teach Themselves

With 100 million first-grade-aged children worldwide having no access to schooling, the One Laptop Per Child organization is trying something new in two remote Ethiopian villages—simply dropping off tablet computers with preloaded programs and seeing what happens.

The goal: to see if illiterate kids with no previous exposure to written words can learn how to read all by themselves, by experimenting with the tablet and its preloaded alphabet-training games, e-books, movies, cartoons, paintings, and other programs.

Early observations are encouraging, said Nicholas Negroponte, OLPC’s founder, at MIT Technology Review’s EmTech conference last week.

After several months, the kids in both villages were still heavily engaged in using and recharging the machines, and had been observed reciting the “alphabet song,” and even spelling words. One boy, exposed to literacy games with animal pictures, opened up a paint program and wrote the word “Lion.” (Read more)

Looking for a fun outdoor project? Take a cue from Swam Rust and calculate a tree’s age.

What does this project explore? You can learn about a tree’s growth and history by observing its rings. Scientists have been able to use the information from the sizes and spacing of tree rings to identify climate change. These studies can also identify trees that are suffering from the early stages of pollution effects or can identify an area that is not getting enough irrigation. Past climate conditions can be discovered and future climate patterns can be predicted from the study of tree rings.

Each fall, millions of monarch butterflies migrate to California and Mexico for winter. North American monarchs are the only butterflies that make such a massive journey (up to 4,830 kilometers/3,000 miles). They use the sun to ensure that they stay on course and on cloudy days Earth’s magnetic field as a kind of backup navigational system. (read more here)
