Periodic table gets a new element

June 11, 2009

The ubiquitous periodic table will soon have a new addition – the “super-heavy” element 112.

More than a decade after experiments first produced a single atom of the element, a team of German scientists has been credited with its discovery.

The team, led by Sigurd Hofmann at the Centre for Heavy Ion Research, must propose a name for their find, before it can be formally added to the table.

Scientists continue the race to discover more super-heavy elements.

Professor Hofmann began his quest to add to the periodic table in 1976.

The fusion experiments he and his colleagues carried out at the centre have already revealed the existence of elements with atomic numbers 107-111.

These are known as “super-heavy elements” – their numbers represent the number of protons which, together with neutrons, give the atom the vast majority of its mass.

To create element 112, Professor Hofmann’s team used a 120m-long particle accelerator to fire a beam of charged zinc atoms (or zinc ions) at lead atoms. Nuclei of the two elements merged, or fused, to form the nucleus of the new element.

These very large and heavy nuclei are also very unstable. They begin to fall apart or “decay” very soon after being formed – within a few milliseconds, in this case.

This releases energy, which scientists can measure to find out the size of the decaying nucleus.

But such experiments produce very few successful fusions, and scientists need increasingly powerful accelerators to run experiments for longer and find the elusive, unstable elements.

This is why it took such a long time for element 112 to be officially recognised by the International Union of Pure and Applied Chemistry (IUPAC).

Its discovery had to be independently verified, and so far only four atoms have ever been observed.

IUPAC temporarily named the element ununbium, as “ununbi” is derived from the figures “one one two” in Latin; but Professor Hofmann’s team now has the task of proposing its official name.

He is currently keeping the shortlist under wraps.

Organic sales grow by 17 percent in 2008

Now that is a positive trend. Take that, Monsanto. Knowledge IS power. Hopefully, this can continue without our biodiversity being totally destroyed by GMOs. Though, I think I read where Monsanto is actually coming out with a NON GMO soybean. Hmmm, do they see that their GMO crap is just a fad? Or will it only say NON GMO on their bags?

Monsanto in the McSpotlight

May 4, 2009

Monsanto is an American-owned international agro-chemical and foods conglomerate. It employs about 45,000 people and peddles over eight billion dollars a year in chemical products all over the world. While Monsanto has been critised for some time for their production of NutraSweet and the genetically engineered rBGH (Bovine Growth Hormone), the latest criticism is for it’s moves into the world of GMOs (genetically manipulated organisams). They produce ‘RoundUp Ready’ soya beans that are genetically altered to be resistant to their chemical herbicide ‘Roundup’ (the biggest selling agro-chemical in the world with sales totalling more than $620 million a year), which provides 40% of the companies operating profit.
Take a look at the Monsanto corporate web site and you might be excused for mistaking Monsanto for a caring company with only our best interests at heart. In ‘The Monsanto Pledge’ (which includes the slogan ‘We pledge to be part of the solution’, the company lays down seven principles that describe the company’s apparent vision for a sustainable environment. They pledge to:

Reduce all toxic and hazardous releases and emissions, working toward an ultimate goal of zero effect;
Ensure no Monsanto operation poses any undue risk to our employees and our communities;
Work to achieve sustainable agriculture through new technology and practices;
Ensure groundwater safety;
Keep our plants open to our communities and involve the community in plant operations;
Manage all corporate real estate, including plant sites, to benefit nature; and
Search worldwide for technology to reduce and eliminate waste from our operations, with the top priority being not making it in the first place.

The propaganda continues with Bob Shapiro, the CEO of Monsanto, declaring;
“We take our responsibilities to our customers, employees, shareowners and people of the world very seriously.”
“..we’re working very hard to make sure our products and manufacturing facilities are safe for the people who use them and for the environment we live in. ”
“..we’re trying to improve people’s lives all over the world.”
“What is important and valuable to you is important and valuable to us.”

It all sounds very nobel but words are just words, and their record tells a different story…
