Amazon Desertification May Start Next Year -- Global Warming Could Increase by 50% -- Note to Self: Find New Planet

Amazon Rainforest Faces Desertification

Amazon rainforest 'could become a desert'

And that could speed up global warming with 'incalculable consequences', says alarming new research

The Independent (U.K.), July 23, 2006

The vast Amazon rainforest is on the brink of being turned into desert, with catastrophic consequences for the world's climate, alarming research suggests. And the process, which would be irreversible, could begin as early as next year.

Studies by the blue-chip Woods Hole Research Centre, carried out in Amazonia, have concluded that the forest cannot withstand more than two consecutive years of drought without breaking down.

Scientists say that this would spread drought into the northern hemisphere, including Britain, and could massively accelerate global warming with incalculable consequences, spinning out of control, a process that might end in the world becoming uninhabitable.

The alarming news comes in the midst of a heatwave gripping Britain and much of Europe and the United States. Temperatures in the south of England reached a July record of 36.3C on Tuesday. And it comes hard on the heels of a warning by an international group of experts, led by the Eastern Orthodox " pope" Bartholomew, last week that the forest is rapidly approaching a " tipping point" that would lead to its total destruction.

The research ­ carried out by the Massachusetts-based Woods Hole centre in Santarem on the Amazon river ­ has taken even the scientists conducting it by surprise. When Dr Dan Nepstead started the experiment in 2002 ­ by covering a chunk of rainforest the size of a football pitch with plastic panels to see how it would cope without rain ­ he surrounded it with sophisticated sensors, expecting to record only minor changes.

The trees managed the first year of drought without difficulty. In the second year, they sunk their roots deeper to find moisture, but survived. But in year three, they started dying. Beginning with the tallest the trees started to come crashing down, exposing the forest floor to the drying sun.

By the end of the year the trees had released more than two-thirds of the carbon dioxide they have stored during their lives, helping to act as a break on global warming. Instead they began accelerating the climate change.

As we report today on pages 28 and 29, the Amazon now appears to be entering its second successive year of drought, raising the possibility that it could start dying next year. The immense forest contains 90 billion tons of carbon, enough in itself to increase the rate of global warming by 50 per cent.

Dr Nepstead expects "mega-fires" rapidly to sweep across the drying jungle. With the trees gone, the soil will bake in the sun and the rainforest could become desert.

Dr Deborah Clark from the University of Missouri, one of the world's top forest ecologists, says the research shows that "the lock has broken" on the Amazon ecosystem. She adds: the Amazon is "headed in a terrible direction".

Ripeness Sticker - Brilliant

A University of Arizona professor has invented a ripeness sticker that shows how ripe a piece of fruit is. Why didn't I think of this!!! This is a simple, brilliant idea. It's right up there with the blue-tip match. The University of Arizona is going to make a lot of money on this.

Electric Currents Heal Wounds

150 years ago, German physiologist Emil Du Bois-Reymond discovered that electric currents could speed up the healing of flesh wounds. But his research has been ignored ever since. Until now...

Now Josef Penninger of the Austrian Institute of Molecular Biotechnology in Vienna and Min Zhao of the University of Aberdeen, UK, have demonstrated that natural electric fields and currents in tissue play a vital role in orchestrating the wound-healing process by attracting repair cells to damaged areas.

(snip)

The researchers grew layers of mouse cells and larger tissues, such as corneas, in the lab. After "wounding" these tissues, they applied varying electric fields to them, and found they could accelerate or completely halt the healing process depending on the orientation and strength of the field (Nature, vol 442, p 457).

Fatherhood Boosts Male Brains

New research has shown that fatherhood brings about dramatic enhancements in male brains. Although the researchers don't suggest it, this effect may be nature's way of counteracting the dramatic decrease in male brain function that occurs in proportion to the number of times they get laid in a given week (Note: this particular malady was brought to national attention on the popular TV show Seinfeld).

This is a really cool science and art project -- Researchers in Japan have developed a device that uses waves to cause images to form on the surface of water. Check the link for a cool picture.

New Level of Order Discovered in DNA

A major new discovery about the structure of DNA molecules has been announced. Researchers have found there is a pattern to the organization of nucleosomes in DNA, which may explain why certain parts of the moleculare are accessible or inaccessible to transcription. This in turn may help explain how certain genes are conserved in nature, and why certain parts of the DNA molecule are more or less vulnerable to mutation and modification.

DNA - the long, thin molecule that carries our hereditary material - is compressed around protein scaffolding in the cell nucleus into tiny spheres called nucleosomes. The bead-like nucleosomes are strung along the entire chromosome, which is itself folded and packaged to fit into the nucleus. What determines how, when and where a nucleosome will be positioned along the DNA sequence? Dr. Eran Segal and research student Yair Field of the Computer Science and Applied Mathematics Department at the Weizmann Institute of Science have succeeded, together with colleagues from Northwestern University in Chicago, in cracking the genetic code that sets the rules for where on the DNA strand the nucleosomes will be situated. Their findings appeared today in Nature.

The benefits of this discovery could be numerous and far reaching...

The team's findings provided insight into another mystery that has long been puzzling molecular biologists: How do cells direct transcription factors to their intended sites on the DNA, as opposed to the many similar but functionally irrelevant sites along the genomic sequence? The short binding sites themselves do not contain enough information for the transcription factors to discern between them. The scientists showed that basic information on the functional relevance of a binding site is at least partially encoded in the nucleosome positioning code: The intended sites are found in nucleosome-free segments, thereby allowing them to be accessed by the various transcription factors. In contrast, spurious binding sites with identical structures that could potentially sidetrack transcription factors are conveniently situated in segments that form nucleosomes, and are thus mostly inaccessible.

Since the proteins that form the core of the nucleosome are among the most evolutionarily conserved in nature, the scientists believe the genetic code they identified should also be conserved in many organisms, including humans. Several diseases, such as cancer, are typically accompanied or caused by mutations in the DNA and the way it organizes into chromosomes. Such mutational processes may be influenced by the relative accessibility of the DNA to various proteins and by the organization of the DNA in the cell nucleus. Therefore, the scientists believe that the nucleosome positioning code they discovered may aid scientists in the future in understanding the mechanisms underlying many diseases.

Kill the Penny

A bill has been proposed to do away with the penny -- that most useless an annoying of coins. Thank you!!!! As far as I'm concerned, if you can't buy a payphone call with it, or 10 to 15 minutes on a parking meter, then it's just not worth having anymore -- so I would also propose getting rid of nickels and dimes too. I proposed this in an earlier blog post here.

Polling the Global Mind

Grupthink is a service where anyone can create and participate in polls on various subjects. It's similar to an idea I once had about polling the global mind in real-time (although their system does not show votes happening in real-time, presently). It reminds me of several other Web 2.0 sites, but it's nicely done. Worth a look.
