The most obvious problems and omissions should have been ironed out by peer review. For a paper as manifestly flawed (or incomplete—take your pick) as Wolfe-Simon’s to be published in a top-tier journal, something went wrong. But I’ll agree that once such a mistake has been made, the (informal) backlash and (formal) technical comments are probably the best way to mitigate the damage." Pretty much says it all. He also criticises the team for their every response being a riposte, as if they couldn'...

Roxarsone contains organic arsenic, which is a less toxic form of arsenic, but this can transform into inorganic arsenic, according to the FDA which, by the way, maintains levels detected were very low and continuing to eat chicken does not pose a health risk. However, chronic exposure is known to cause cancer and has been linked to heart disease, diabetes and declining brain function. Organic arsenic is added to the feed of most roasters grown in...

So like many other people, I’ve been following the “arsenic life” story with great interest. It seems that far more has been written about the publication, the manner of its announcement, the ensuing online debate and the personalities involved than about the principal scientific question: can arsenate substitute for phosphate in biological molecules? My opinion, for what it’s worth, is that the Science paper presented no compelling evidence for covalently-bound As in DNA and that the editors should have asked the authors either to do better experiments or tone it down. Now, Nature News reports that the criticisms are in, the authors ha...

For one, this only reinforces my feeling that most of the things that are published on Nature and Science are just things that will sell more paper, and reinforces my will to not read most of the papers from these journals I would expect in the coming years to meet students that...

Arsenic (As) is a chemical analog of phosphorus and is usually toxic because it can enter metabolic pathways in the place of phosphorus. It appears to be incorporated into macromolecules of the bacterium (called GFAJ-1) that normally contain phosphorus, such as nucleic acids and proteins. The identification of bacteria that can utilize arsenic has many metabolic and evolutionary implications. I’m wondering whether there are viruses that infect bacteria such as GFAJ-1. It has been suggested that Mono Lake contains organisms that are biologically distinct from all others so far discovered on Earth.

Canned heavy metal – Samples of tinned sardines, originating from six countries have been analyzed for total arsenic, cadmium, lead and mercury content using spectroscopy.

Exposure to lead can result in a number of harmful effects, and a developing child is particularly at risk of effects on the brain and nervous system. Arsenic is a carcinogen, and excessive long-term exposure to it has been associated with a range of adverse health effects, including cancers of the urinary bladder, lung and skin. Nzu,...

The factory scraps of melamine kept disappearing but no one raised any questions. The melamine resulted in many kidney failures and some deaths.  The milk was made into candies and shipped to us and other countries.  All this has been recalled.   Additives have long helped farmers fool the dairy company tests from protein, fat content...
