An urgent review is underway after an ABC Four Corners investigation found elevated levels of dangerous dibenzo-para-dioxins – dioxins – in a generic version of 24D, one of Australia’s most widely used herbicides. 2,4-D is used in many commercial products including; Bayer All-In-One, Nufarm, Kuziherb, Hi-Yield, Weedtrine, Aqua-Kleen, Barrage, Plantgard, Lawn-Keep, Planotox, Malerbane, Speedzone and Dupont 24D. While this latest scare focuses on commercially used chemicals, it is likely that domestic-use herbicides and pesticides contain the same dioxins.
Dioxins are one of the most toxic chemical compounds in the world – Australian authorities don’t routinely test for them – dioxins break down extremely slowly in the environment, they bioaccumulate – collect in fatty tissue – becoming concentrated in animals higher up the food chain. Dioxins are almost exclusively man-made. In herbicides 2,4-D is used widely to control many types of broadleaf weed, and belongs to the Dirty Dozen Persistent Organic Chemicals – POPs – the production of which was banned in 2001.
Dioxins are formed during chemical manufacturing – especially herbacides/pesticides – in pulp/paper manufacture during chlorination and burning and high temperature processes such as metal sintering, there are 76 different chlorinated dioxins. This current scare raises a couple of serious questions; Who’s watching what chemicals are being used in our food production industries? Certainly not the regulators. The scare also highlights serious flaws in the regulating of foreign manufactured chemicals, the quality of Chinese and Indian manufactured products must surely be questioned? AND, why don’t Australian regulators routinely test chemicals being used to grow our food? :: Read the full article »»»»

Australian researchers have discovered a key factor explaining the lack of effectiveness of some breast cancer treatments. Associate Professor Chris Ormandy from Sydney’s Garvan Institute says a protein he has been studying for a decade plays a critical role in the development of breast cancer.
The researchers have shown how a ‘transcription factor’ causes breast cancer to develop an aggressive subtype that lacks sensitivity to oestrogen and does not respond to anti-oestrogen therapies such as Tamoxifen and aromatase inhibitors.
Transcription factors are molecules that switch genes on or off. In this case, the transcription factor known as ‘ELF5’ inhibits sensitivity to oestrogen very early in the life of a breast cancer cell :: Read the full article »»»»

Researchers have found that Botox can significantly reduce the severity of tremors in patients with the debilitating inflammatory disease, Multiple Sclerosis.
Researchers injected 23 patients with either Botox or a placebo over six months during the trial at the Royal Melbourne Hospital. They then videoed the volunteers to see if the botox made a difference.
Multiple sclerosis (MS), also known as “disseminated sclerosis” or “encephalomyelitis disseminata”, is an inflammatory disease in which the fatty myelin sheaths around the axons of the brain and spinal cord are damaged, leading to demyelination and scarring as well as a broad spectrum of signs and symptoms.
Disease onset usually occurs in young adults, and it is more common in women. It has a prevalence that ranges between 2 and 150 per 100,000. MS was first described in 1868 by Jean-Martin Charcot :: Read the full article »»»»

Back in July 2011 we published an exciting little post on MIT’s work with artificial leaves – MITs Artificial Leaf – based on a silicon solar cell.
The leaf consists of a thin, flat, three-layered silicon solar cell with catalysts bonded to both faces of the silicon. Placed in water and exposed to sunlight, silicon absorbs photons of sunlight, generating electrons with enough energy to conduct through the silicon.
The process leaves behind positively charged electron vacancies called “holes” that can also move through the material. The holes migrate to a cobalt-containing catalyst painted on one face of the silicon cell, where they strip electrons from water molecules, breaking them into hydrogen ions (H+), and oxygen atoms. The catalyst then knits pairs of oxygens together to make O2. Meanwhile, the H+ ions migrate to another catalyst on the opposite face of the silicon cell, where they combine with conducting electrons to make molecules of H2. In principle, the H2 can then be stored and either burned or run through a fuel cell to generate electricity.
Professor Daniel Nocera’s work has finally borne fruit. Nocera’s team developed the catalyst three years ago, the first practical artificial leaf has now been developed, and this new technology may help to deliver efficient carbon neutral energy to the world’s poor and developing nations.
Building on their previous research, the researchers at MIT in Boston have created an artificial leaf that, unlike earlier devices is made from inexpensive materials, and employs low-cost engineering and manufacturing processes :: Read the full article »»»»

The US Department of Agriculture – USDA – has reported the country’s fourth case of bovine spongiform encephalopathy – BSE – in a Californian dairy cow, but stressed the outbreak was contained and no meat had entered the food chain.
The first reported BSE case in North America was in December 1993 from Alberta, Canada.
Canadian Agricultural Authorities reported another case reported in May 2003. The first known U.S. occurrence of BSE came in December of the same year though it was later confirmed that it was a cow of Canadian origin and imported to the U.S. Canada announced two additional cases of BSE from Alberta in early 2005.
In June 2005 Dr. John Clifford, chief veterinary officer for the United States Department of Agriculture animal health inspection service, confirmed a fully domestic case of BSE in Texas. Dr. Clifford would not identify the ranch, calling that “privileged information”. The 2005 US BSE case caused the nation’s beef exports to drop by nearly $3 billion the following year. BSE cannot be transmitted through milk.
This latest case of BSE was found in a dairy cow on April 23, in California during a planned Agriculture Department surveillance program. United States health authorities were quick to point out that the animal was never a threat to the nation’s food supply and claim that this is an atypical case of BSE caused by “just a random mutation that can happen every once in a great while in an animal” :: Read the full article »»»»
