Kids Can Divde by Zero

A professor in the UK has come up with a new number (really it’s a non-number-number) that means we no longer have to divide by zero. Instead, zero is replaced with “nullity,” which is nothing times infinity.

“The theory of nullity is set to make all kinds of sums possible that, previously, scientists and computers couldn’t work around.

“We’ve just solved a problem that hasn’t been solved for twelve hundred years – and it’s that easy,” proclaims Dr Anderson having demonstrated his solution on a whiteboard at Highdown School, in Emmer Green.”

Mottainai Furoshiki

In Japan the Minster of the Environment has started a neat way to raise awareness about wastefulness.

“Ms Yuriko Koike, Minister of the Environment, has created the “Mottainai Furoshiki” as a symbol of Japanese culture to reduce waste. Furoshiki is a Japanese traditional wrapping cloth which is used repeatedly in a stylish way. (The utilization of this “Mottainai Furoshiki” will contribute to reducing household waste from plastic bags.) The Minister presented the “Mottainai Furoshiki” at the Senior Officials Meeting on the 3R Initiative held in Tokyo, Japan on March 6-8, 2006″

Corporations and Society

noradawn wrote us to tell us about corporate social responsibility (CSR):

“Are corporate giants waking up? The increase of public demand for more sustainable and socially responsible practices is causing the giants of the business world to reevaluate how they do things and start implementing new practices. In essence, doing what they can to save the world. This practice commonly called CSR is being seen more and more in giants such as Wal-Mart, Levi & Strauss, and Hasbro to name a few.

The trend was started by smaller, socially and environmentally aware companies such as Tom’s of maine toothpaste and Ben and Jerry’s ice cream, who pioneered this concept…and wound up having incredible growth rates. In turn, this caused the larger companies to turn their heads to see what they were doing right from a business perspective. As a result, it looks like it is the new trend that is emerging, and the corporate giants…many of whom have more capital than some entire countries- are the ones with the dollars and cents to really help in making a big difference.”

For more on CSR this noradawn suggests this good article on CSR.

Thanks noradawn for sharing this!

Discovery: How Folic Acid is Absorbed

Scientists have discovered how the vitamin folate is absorbed in the intestinal tract.  The discovery may lead to being able to test infants that cannot absorb this important nutrient.folic acid_1.jpg

Folate, also known as folic acid or vitamin B9, is important for growth and gene expression in the fetus.  Babies who are deficient in it, or cannot absorb it, may have mental retardation, seizures, severe infections, or anemia.

Until now, scientists were not sure what mechanism the body used to absorb folate.  This vitamin is water soluble, therefore not easily penetrating fatty cell membranes.  Recent research at the Albert Einstein Cancer Center in New York concludes that a membrane protein called PCFT/HCP1 transports folate into intestinal cells.

This discovery may help cure hereditary folate malabsorption in babies.

Psiphon Fights Censorship

Earlier this year we covered that Citizen Lab at the University of Toronto was creating some software called Psiphon that lets people bypass firewalls. Psiphone is designed to let people access sites that are blocked for censorship reasons like in China where there is a lot of online censorship.

“psiphon is a censorship circumvention solution that allows users to access blocked sites in countries where the Internet is censored. psiphon turns a regular home computer into a personal, encrypted server capable of retrieving and displaying web pages anywhere.”
