How Electricity Works

As electrons leave those atoms nearest the positive end, they leave behind positively charged atoms. Electrons from neighbouring atoms will be attracted towards these positive atoms thus creating yet more positive atoms in their wake. This continuing transfer of electrons is called current.

What if We Send Microbes to Terra to Form Another Planet?

How would you go about terra forming another planet? Well you could send microbes to start organic life. Of course it will take 4 billion years to do it judging from our knowledge of our planet.

What if a Living Planet Got Hungry?

Some believe that there may be planets out there, which are totally organic? That is to say they are totally alive. Teaming with Microbial life which has eaten all the elements and compounds of the planet all the way thru.

Science Lessons for Grade 1 on the Five Senses

Finding appropriate experiments to use with Science lessons for Grade 1 on the five senses is often a difficult task for teachers. This is because the experiments have to be very simple in order for the students to be able to do them.

The Glass We Know

Sirt1 Gene is Required for the Increase in Physical Activity Induced by Caloric Restrictions

Caloric restriction (CR) is the best known approach to extend organism’s lifespan. It works remarkably well in various living beings, from yeast to mice. It is likely also to work in primates and humans. If an animal lives under CR, essentially semi-starving, one may think that it will try to preserve its energy by reducing physical activity. Apparently, this is not the case. For example, mice in reality move more and demonstrate increased foraging activity while on a restricted diet. This does make sense as far as individual’s survival is concerned. In the wild, mice confronted with food shortage are more likely to find more food when they try to search for it than if they simply sit there hoping for a piece of cheese to appear out of thin air.

Why Does The Tool Bit Break Easily In Micro Milling?

While micro milling has been successfully applied in manufacturing bio-medical components, embossing dies and micro encoders, the breakage of the tool bit has been identified by many users as a teething problem. Why does the tool bit break so easily in micro milling as compared to conventional milling?

How To Make Lighter and Thinner Magnesium Components?

The most common methods to produce magnesium parts are die casting and thixomolding processes. However, these runner and gating processes provide a low material yield of only 30% for thin-wall casting and can only produce thin walls of between 0.7mm to 1.2mm. If we can form magnesium parts from sheet metal just like metal stamping of steel and aluminum parts, we can achieve better material yield of about 80% and possibly safer operation due to the lower processing temperature.

Celestial Phenomena for 2006: Solar and Lunar Eclipses

During the course of 2006, a number of celestial phenomena such as solar and lunar eclipses, meteor showers and planets, among others, will be visible, most with the naked eye. In part 1 of this series, equinoxes and solstices were discussed. Depending on where you live, you can mark your calendar and plan on taking advantage of some of these other visible celestial phenomena, local weather conditions permitting. In this article, part 2 of a three-part series, upcoming full or partial lunar and solar eclipses in 2006 will be discussed.

Space Exploration - What's Out There?

Space Exploration has been the quest to use space travel to discover the nature of the universe beyond the earth.
