Paper that Self-Erases in a day

As what i have read on the Treehugger site, Xerox has came out with a paper that self-erases within 24 hours and can then be re-used. The printing on the paper will fade gradually in 24 hours under the light is actually due to a compound on the printing that change colour when they absorb a certain wavelength of light. The printing can also be erased faster by exposing to heat. The erasable paper produced by Xerox has not yet on sale. It is because it is still a research project. I enjoyed reading the article as it is quite a good idea to help in reducing paper used. And i do believe the erasable paper could help in reducing the number of paper in the world. However, Xerox still need to think how they should reduce the cost of production of the erasable and the ways to attract the consumers to use their product.

Electronic cigarettes

Have you ever heard of electronic cigarettes? Now, as what i have read on BBC news website, the sales of the electronic cigarettes has been raised in UK. The electronic cigarettes use replaceable cartridge with shots of nicotine, but have become popular because they are not covered by the smoking ban. Some of the smokers believe that the cigarettes were healthier than normal cigarettes as they do not contain tar, tobacco or carbon monoxide. Yet, experts are worried as users inhale a fine heated mist and there is a lack of regulation. However, Jason Cropper, managing director of the Electronic Cigarette Company, has claimed that it is more healthier than the real cigarettes as they had done the experiment on mice. I do not enjoyed reading the article because it does not related to me and i think electronic cigarettes could not help in cutting down the number of smokers. Those smokers will think that electronic cigarettes is more healthier than the real cigarettes yet they forget inside the cigarettes still contain nicotine.

Yummy Yummy Chocolate

CHOCOLATES...mainly made from cocoa is indeed good for ones brain and bring various benefits to ones healthy yet happy life style. Don't worry too much of the fat contain in chocolates..Why don't you cut down on your french fries or fried chicken? Eat up chocolate moderately as it also enhances good mood!Several recent studies suggest that some types of cocoa contain substances that could enhance blood flow in the brain and improve brain function. Although it is a little distressing that the conference at which this breakthrough was discussed was sponsored by Mars Incorporated, the candy maker, it did point to compounds known as Flavanois as to their ability to keep the brain healthy and prevent cognitive decline and dementia.Scientist in England believe that drinks containing this compound could be used to treat vascular impairments in the brain. After consumption of the liquid, it was noted that there was increased blood flow to the gray matter, which is part of the brain stucture, for two to three hours.

How does the roller coaster work?

What you may not realize as you’re cruising down the track at 100 kilometre hour is that the coaster has no engine. The car is pulled to the top of the first hill at the beginning of the ride, but after that the coaster must complete the ride on its own. You are not being propelled around the track by a motor or pulled by a hitch. The conservation of potential energy to kinetic energy is what drives the roller coaster and all of the kinetic energy you need for the ride is present once the coaster descends the first hill. Once you are underway, different type of wheels help keep the ride smooth. Running wheels guide the coaster on the track. Friction wheels control lateral motion (movement to either side of the track). A final set of wheels keeps the coaster on the track even it is inverted. Compressed air brakes stop the car as the ride ends.

It is very cold and dark. from what i read the planet was discovered by the Samuel Oschin Telescope at the Palomar Observatory near San Diego, Calif., on Jan. 8, 2005.

weird things happen

we have so many tyme saw or heard about wierd things that happen without any explanation. this is the one of the weird case that i had read from the website thatsweird.net. Thousands of jumbo flying squid or Humboldt squid, were found stranded on southern California beaches over the summer of 2002. The normal range of these squid, also known as Humboldt squid, is from Peru north to Baja California. However, warm water events such as El Niño can extend the range of these squid to Oregon.The first reported stranding was on July 18 at Swami’s Beach in Encinitas, CA, where approximately 200 squid were found over a mile stretch of shore. Their mantle lengths ranged from 16 to 24 inches, and they weighed between 2 and 2.5 pounds. On July 25, several thousand squid beached themselves at La Jolla Shores (pictured above), about 15 miles north of San Diego. Scientiests believe they squid were following prey, possibly grunion, a small fish, and washed ashore alive but were unable to get back into the water and died. City work crews were called to help remove tons of dead fish.
