which is toxic and corrodes pipelines and transportation vessels Tour said. The extra steps required to turn the sour into sweet crude are costly.
Grasses take up this toxic heavy metal which is eaten then by the cattle and sheep that graze them.
which releases toxic hydrogen cyanide to keep the kernels from being eaten. Wheat seeds are coated with substances that also form hydrocyanic acid
In the Polar regions many seabirds such as skuas were known to accumulate this toxic element at high levels in their tissues.
Prions are misfolded toxic versions of a protein called Prp which in its normal form is present in all mammalian species that have been examined.
Toxic prions are infectious; they can induce existing properly folded Prp proteins to convert into the disease-associated prion form.
The scientists then exposed young mice to toxic misfolded prions from 8 different species including human cattle elk sheep and hamster.
which toxic prions convert healthy Prp and thereby destroy the brain. And because that process is similar across many neurodegenerative diseases better understanding prion disease development might have broader implications.
In the laboratory the researchers could see how the fungicide-exposed worms adapted to the toxic environment.
Roundwormsthe banana variety Yangambi km5 produces toxic substances that kill the nematode Radopholus similis a roundworm that infects the root tissue of banana plants--to the frustration of farmers worldwide.
Synthetic pesticides are toxic and expensive. Moreover pesticides usually do not actually kill the nematodes they just temporarily paralyze them.
Nicotine is not toxic for the body; it creates an addiction but it is not particularly harmful.
Bt is a soil bacterium that produces proteins that are toxic to some species of caterpillars
but are not toxic to people wildlife or even most insects. Organic growers have used Bt toxins in sprays for decades
These losses can become larger as under certain conditions the fusarium pathogen produces toxic chemicals known as mycotoxins.
While these pheromones can be made chemically it can be a toxic process to produce them Durrett said.
What we demonstrated in this study is a more environmentally friendly approach that avoids the need to use toxic chemicals
so it's no longer toxic. They have shown also that this gene makes insects resistant to pyrethroids raising the concern that GSTE2 gene could protect mosquitoes against the major insecticides used in public health.
which may prevent the formation of toxic plaque that leads to Alzheimer's disease. Dr. Sirna warns that you should drink in moderation by consuming no more than one 5-ounce glass for women and two 5-ounce glasses for men.
and it's about as toxic as salt. It takes very little to elevate all the desirable aspects.
which converts aldehydes highly toxic to dopamine cells into less toxic agents and therefore contributed to the development of Parkinson's.
or otherwise eliminating toxic aldehydes should be developed and tested to potentially reduce Parkinson's disease occurrence
but many plants are toxic and potentially deadly. So how do babies learn what's good to eat and
Although the levels of DDT and DDE have decreased significantly in the United states over the last three decades the toxic pesticide is still found in 75 to 80 percent of the blood samples collected from the Centers for Disease Control and Prevention.
or inactive chemical commonly used as a pesticide additive--is highly toxic to honeybee larvae.
or in concert to create a toxic environment for honeybee growth and development. The researchers also investigated the effects of NMP on honeybee larvae by adding seven concentrations of the chemical to a pollen-derived royal jelly diet.
This is the first study to report serious toxic effects on developing honeybee larvae of dietary pesticides at concentrations that currently occur in hives.
Toxic viral cocktails appear to have a strong link with honey bee Colony Collapse Disorder (CCD) a mysterious malady that abruptly wiped out entire hives across the United states
The work out in Current Biology looked into the mechanism that allowed gregarious locusts to change their diet surprisingly fast--just a few hours after solitarious locusts are crowded they are eating toxic plants
To Simå es and colleagues'surprise it was found that this was due to an incapacity by newly gregarious locusts to acquire negative/aversive memories that made them on encountering toxic plants see these as appetitive.
and its protection against predators (toxic plants make locusts unpalatable) how could such major adaptation occur in just a few hours?
So next Simå es and colleagues used hyoscyamine--a toxic alkaloid substance present in plants of the locust's natural habitat that are avoided by solitarious forms (because of their bad taste)
when locusts are exposed re to the toxic plants. This capacity to override previous memories which only occurs during the initial stages of gregarization/crowding is crucial for survival in the swarm because with increasing numbers of individuals also raises not only competition for food but also exposure to predators.
The reason why later gregarious locusts continue to eat toxic plants despite being able to gain aversive memories lies in their learning mechanism.
, in highly toxic and dangerous petrochemical plants. Less than 5 percent of plastic is recycled, he said;
in compliance with Google's famed Red List that focuses on removing toxic ingredients of materials.
when formula was found to be tainted with the toxic substance melamine. Hong kong has held long the title of having the freest economy in the world, with few taxes and trade regulations.
One answer to toxic food fears in Chinathe fear among Chinese of biting into a toxic-laden morsel has created a potentially huge market for food safety products in the country.
The weekly reports of toxic bean sprouts, milk containing leather-hydrolyzed protein, aluminum-tainted dumplings and cadmium-laced rice is enough to make anyone wary of
but are also literally killing themselves from inhaling the toxic soot. These are things we should be doing right away to buy us some time to solve the harder problem of how to stop burning fossil fuels.
The process must first pre-treat the wood's toxic sap, which can be harmful to the bacteria used in the fermentation process.
Mr. Anderson and farmers throughout the East, idwest and South are being forced to spray fields with more toxic herbicides,
and a new generation of crops designed to be drenched in toxic chemicals.''We have to figure out this fusion of industrial and organic.
