This article describes a material called indium sulfate. It is vaunted at NaturalHealthConsult.com as a “rare trace mineral that supports several hormonal systems in the body. Indium may strongly elevate immune activity and reduce the severity and duration of a myriad of human conditions.” The site also claims that studies were performed on it by a Dr. Schroeder, who "figured out how to remove lead from gasoline."

The article points out that while Dr. Henry A. Schroeder did study lead toxicity, there is no natural lead in gasoline. Lead was an added anti-knocking agent

Toxicity is the question: Bisphenol-A on trial in Canada

Darkfrog submitted, created time 8 months 3 weeks (www.nytimes.com)

Bisphenol-a is a molecule found in many common rigid plastics. It also acts as an estrogen mimic in many different types of animals, including humans, causing or potentially causing lowered sperm count, increased risk of breask cancer, infertility in men and both toxic and neurotoxic effects. The Canadian government is preparing to label bisphenol-a as "toxic," and thereby forbidding it to be used in plastics that are meant to contain food or drink, such as baby bottles, water bottles and the linings of cans

he drive also promises to cut costs, and improve testing accuracy. Scientists will research and develop the capacity to test new chemicals and drugs on cultured human cells, according to a five-year memorandum of understanding signed on Thursday between two US National Institute of Health bodies and the US Environmental Protection Agency.

"High-dose immunosuppression and AHST were performed with acceptable toxicity in a small number of patients with newly diagnosed type 1 DM. With AHST, beta cell function was increased in all but 1 patient and induced prolonged insulin independence in the majority of the patients. "

Foscarnet, an inhibitor that blocks the reverse transcriptase (RT) enzyme and counteracts resistance to common anti-HIV drugs such as AZT, is sometimes used in patients with multiple drug-resistant HIV-1 when no other treatment options are available. However, its clinical practicality is severely limited by the risk of serious side effects, including diabetes, kidney toxicity, irregular heartbeat, nausea, fever and rash.

How to distribution, diversity and ecology of aerobic CO-oxidizing bacteria?

humane-wolf submitted, created time 1 year 11 months (www.nature.com)

Numerous studies indicate that carbon monoxide (CO) participates in a broader range of processes than any other single molecule, ranging from subcellular to planetary scales. Despite its toxicity to many organisms, a diverse group of bacteria that span multiple phylogenetic lineages metabolize CO. These bacteria are globally distributed and include pathogens, plant symbionts and biogeochemically important lineages in soils and the oceans. New molecular and isolation techniques, as well as genome sequencing, have greatly expandedour knowledge of the diversity of CO oxidizers
