National Academies advisory: genes and toxic chemicals
Research is increasingly revealing how toxic chemicals disrupt gene activity and other cell processes in ways that lead to health problems -- and why some individuals are particularly vulnerable. view more (2007-10-05)
Helping the aged gut replace good bacteria may reduce cancer risk
Eating certain foods can increase the number of protective microbes in the gut. These bacteria help prevent food poisoning and can reduce levels of some toxic chemicals that may cause cancer, scientists heard today (Wednesday 10 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick. "We have... view more... (2002-04-02)
Electronic nose sniffs out toxins
Imagine a polka-dotted postage stamp-sized sensor that can sniff out some known poisonous gases and toxins and show the results simply by changing colors. view more (2009-09-14)
Radioactive waste – no problem for metal-munching bacteria
A harmless soil bacterium, which can survive high-level exposures to gamma radiation, is being developed to clean up land contaminated with radioactive waste, experts heard today (Wednesday 12 September 2001) at the bi-annual meeting of the Society of General Microbiology at the University of East Anglia. US government researcher Dr. Michael Daly... view more... (2001-09-07)
Disinfectants can make bacteria resistant to treatment
Chemicals used in the environment to kill bacteria could be making them stronger, according to a paper published in the October issue of the journal Microbiology. Low levels of these chemicals, called biocides, can make the potentially lethal bacterium Staphylococcus aureus remove toxic chemicals from the cell even more efficiently, potentially... view more...

The microbial hydrocarbon diet
Bioremediation of industrial sites and petrochemical spillages often involves finding microbes that can gorge themselves on the toxic chemicals. This leaves behind a non-toxic residue or mineralized material. view more (2009-06-12)
New AQUIRE database on STN: Toxic Effects of Chemicals to Aquatic Organisms
Karlsruhe, October 2002 - FIZ Karlsruhe, European partner of STN International, one of the world's leading online providers of scientific and technical information, has announced the launch of the AQUIRE database. AQUIRE contains scientific papers published both nationally and internationally on the toxic effects of chemicals to aquatic organisms... view more... (2002-10-18)
New toxicity test could cut animal testing
To test whether chemicals are toxic to humans, researchers need to use liver cells that have been freshly harvested from mice or other mammals. A new collection of stable cell lines, described in BMC Biotechnology this week, could reduce the numbers of animals needed in such experiments. The MMH-GH cell lines are derived from the liver cells of... view more... (2004-03-17)
The secret behind silkworm's hardy stomachs
Silkworms have a unique ability to eat toxic mulberry leaves without feeling ill, and researchers have come one step closer to understanding why: silkworms contain a special digestive enzyme that is not affected by mulberry's toxic chemicals. view more (2008-05-28)
Unlocking the body's defenses against cancer
Scientists have discovered a way of allowing healthy cells to take charge of cancerous cells and stop them developing into tumours in what could provide a new approach to treating early-stage cancers. view more (2009-08-26)
New bug to tackle pollution
A new, all-natural, pollutant-busting microbe has been discovered by scientists in Germany. Research published in the October 2003 issue of Microbiology, a Society for General Microbiology journal, describes a new strain of bacterium, which could be used in the near future to clean up polluted land. Over the years, many harsh and highly toxic... view more... (2003-10-10)
Smoking out the mediators of airway damage caused by pollutants
New insight into how pollution and cigarette smoke damage airways has been provided by Pierangelo Geppetti and colleagues, at the University of Florence, Italy, who studied the effects of such chemicals on guinea pig airways. view more (2008-06-23)
Environmental toxicants like lead, mercury target stem cells
Low levels of toxic substances cause critical stem cells in the central nervous system to prematurely shut down. That is the conclusion of a study published today in the on-line journal PLoS Biology. view more (2007-02-06)

Toxic chemicals affect steroid hormones differently in humans and invertebrates
In a study with important consequences for studies on the effects of chemicals on steroid responses in humans, a team of French and American scientists, including Michael E. Baker, PhD, professor in UC San Diego's Department of Medicine, Division of Nephrology-Hypertension, have found that - contrary to earlier assumptions - enzymes used for the... view more...

A silent pandemic: Industrial chemicals are impairing the brain development of children worldwide
Fetal and early childhood exposures to industrial chemicals in the environment can damage the developing brain and can lead to neurodevelopmental disorders (NDDs)-autism, attention deficit disorder (ADHD), and mental retardation. view more (2006-11-08)
EPA new strategic plan for evaluating the toxicity of chemicals
EPA is releasing a new approach to advance the science upon which the agency bases its regulatory decisions and policies, resulting in better protection for human health and the environment. view more (2009-03-26)
Could Chemicals From Algae Help Fight Lung Cancer?
Unusually the active chemicals are simple oils and Professor Rowland's team has been able to identify them fully - even including their 3-D shapes. Such simple chemicals may be easy to manufacture on a large scale. 'If not,' says Dr Simon Belt, one of the team leaders, 'we have a plentiful suppl;y of the rare alga because it is used in France as a... view more... (1998-12-23)
The memory lingers longer
PCBs and dieldrin, for example, now banned for further industrial and agricultural use, are simply not breaking down in the environment as speedily as needed to meet environmental targets. Catchments of rivers in west Yorkshire with a long history of contamination by chemicals used in the wool-processing industry show persistent levels of these... view more... (1999-12-22)
