which stops the production of a protective toxic resin released by the tree and allows the beetles to continue to infest.
The US Environmental protection agency (EPA) has agreed to set new rules governing emissions of mercury and other toxic chemicals from power plants by November 2011,
The US Environmental protection agency (EPA) laid out White house-backed principles for a radical reform of US legislation regulating toxic chemicals, at present controlled by the 1976 Toxic Substances Control Act.

The US government should grade microorganisms and toxins according to their risk as potential biothreat agents,
That was the recommendation of a National Research Council report released last week, entitled Responsible Research with Biological Select Agents and Toxins.
The researchers also found that frog larvae in small artificial ponds showed few toxic effects from glyphosate exposure
Everyone agrees on concentrations that cause toxicity says Reinier Mann, an ecotoxicologist at the University of Technology in Sydney, Australia.
then it is quite possible that you will get concentrations that cause toxicity, Mann says.
This finding contrasts with earlier research6, 7 that reported glyphosate had highly toxic effects on human cells in vitro.
The issue of protecting the toxin as it passes through the stomach to be released in the intestine will have to be addressed

which are engineered to produce pest-killing toxins from the bacterium Bacillus thuringiensis, use less insecticide. Increased planting of herbicide-tolerant crops may also have reduced the use of many herbicides that linger in soil and waterways
Nature Newsgrowing cotton that has been modified genetically to poison its main pest can lead to a boom in the numbers of other insects,
In 1997, the Chinese government approved the commercial cultivation of cotton plants genetically modified to produce a toxin from the bacteria Bacillus thuringiensis (Bt) that is deadly to the bollworm Helicoverpa armigera.
Mirids are not susceptible to the Bt toxin so they started to thrive when farmers used less pesticide,
and is considered to be the least toxic alternative to chemical pesticides. But a new study has revealed adverse effects on the reproductive success of birds.

assessed the effects of planting maize (corn) genetically modified to produce Bt toxin, which kills the European corn borer (Ostrinia nubilalis).
Conventional growers also help to stop corn borers becoming resistant to the Bt toxin by hosting pest populations that are susceptible to it, according to the team's research.
the corn earworm (Helicoverpa zea), has evolved resistance to Bt toxin in situations where GM-crop coverage is 100%.
and genetically modified cotton crops, engineered to produce a toxin deadly to pinkies, would put an end to farmers'costly struggle against the caterpillars.
The strategy was intended to restrict the spread of toxin-resistant pink bollworms by flooding the population with sterile moths.
Arizona farmers had to give up the strategies normally used to suppress toxin-resistant bollworms so
The crops produce a toxin that is made naturally by the bacterium Bacillus thuringiensis called Bt toxin.
To prevent the spread of Bt resistance, farmers are required to plant nearby'refuges'of conventional crops.

H4, makes Shiga toxin, which is responsible for the severe diarrhoea and kidney damage in patients
The genes for the Shiga toxin are not actually bacterial genes, but phage genes being expressed by infected bacteria.
So when an E coli bacterium gets infected with a Shiga-toxin-producing phage, it becomes pathogenic to humans.
It also releases the toxin, which is why antibiotics are used not usually to treat E coli infections (see'Europe's E coli outbreak:

Shiga toxins have been causing diarrhoeal disease in humans for centuries the bacterial genus Shigella and the Shiga toxins were named first for Kiyoshi Shiga,
a Japanese medical doctor who identified the bacterium during an outbreak of dysentery in Japan in 1897.
According to Allison, Shiga-toxin producing phage probably picked up the genes encoding Shiga toxin from these bacteria,
We are seeing more and more Shiga-toxin-producing strains says Alison Weiss, microbiologist at the University of Cincinnati in Ohio.
How have Shiga-toxin-producing phage spread so widely in just a few decades? Allison says they have unusual characteristics that make them very successful.
but Shiga-toxin-producing phage can infect the same cell multiple times, giving them greater pathogenic potential.
The toxins kill the other microbes, giving these bacteria an advantage. Not only are more E coli strains being infected with Shiga toxin,
but it seems to be moving into different classes of bacteria. The genome of strain O104:
and EAEC and Shiga toxin is a very unusual combination, says Caprioli. This increased movement of Shiga-toxin-producing phage means that even more unusual and dangerous strains could be on the horizon.

Incineration uses a tremendous amount of heat to turn the toxic chemical into mostly ash water vapor and carbon dioxide.
Weapons of War-Poison gas Considered uncivilised prior to World war One the development and use of poison gas was necessitated by the requirement of wartime armies to find new ways of overcoming the stalemate of unexpected trench warfare.
Introduction of Poison gas The debut of the first poison gas however-in this instance chlorine-came on 22 april 1915 at the start of the Second battle of ypres.
and the use of poison gas continued to escalate for the remainder of the war. Allied Retaliation Once the Allies had recovered from the initial shock of the Germans'practical application of poison gas warfare a determination existed to exact retaliatory revenge at the earliest opportunity.
The british were the first to respond. Raising Special Gas companies in the wake of the Germans'April attack (of approximately 1400 men) operating under the command of Lieutenant-colonel Charles Foulkes instructions were given to prepare for a gas attack at Loos in September 1915.
By 1918 the use of use of poison gases had become widespread particularly on the Western Front.
If the war had continued into 1919 both sides had planned on inserting poison gases into 30%-50%of manufactured shells.
The french army occasionally made use of a nerve gas obtained from prussic acid. However three forms of gas remained the most widely used:
In large part this was because of the increasing effectiveness of the methods used to protect against poison gas.
and disgust at the wartime use of poison gases that its use was outlawed in 1925-a ban that is at least nominally still in force today...
If the containers were designed to leak slowly the poisons may dissipate enough to become harmless.

And then they become a poison. And banned and bad mounted substances are actually crucial.

Companies are also likely developing new GMO crops perhaps with more insect toxins engineered into them to combat the newly evolved resistance.

#Eating Poo Helps Packrats Digest Toxic Plantsdesert woodrats are picky but not in the way you might expect:
several woodrat populations in the U s. Southwest specifically eat a type of highly toxic creosote bush.
Another group eats juniper which is also toxic to many animals. This gives the woodrats (Neotoma lepida) a nice niche allowing them to dine on a plant that others avoid.
A new study suggests that the microbes in their gut break down the toxic chemicals in the plants
and lost weight whereas animals given rabbit food (devoid of toxins) seemed to do just fine and didn't lose weight.
These animals apparently developed the ability to break down the plant compared to those just fed rabbit food who couldn't subsequently eat the toxic plant.
All this work with toxic plants poo and packrats has wider implications than you might imagine however.
It may be possible for example to help livestock feed on toxic plants like juniper which is spreading throughout the Southwest
since breeding in the lab can cause the animals to lose microbes necessary for digesting certain toxic plant compounds found in the wild.
