Experts believe the venom in the sting helps ease the pain of MS symptoms and also stimulates the body to fight back Sami says she was stung around 1,

Bee Venom Therapy, or Apitherapy, uses the stings of live bees to relieve symptoms of MS such as pain, loss of coordination,

Researchers suggest that certain compounds in bee venom reduce inflammation and pain and a combination of all its ingredients helps the body to release natural healing compounds.

#Explosives and Pesticides Can Be detected by Using Bee Venom MIT scientists discover that bee venom can detect explosives and some pesticides.

Scientists from MIT have discovered that by coating carbon nanotubes in bee venom, they can create ultra-sensitive detectors for explosives such as TNT,

and fellow chemical engineers coated one-atom-thick tubes of carbon with protein fragments found in bee venom,

Its certainly an interesting use of venom especially after we recently saw that scorpion venom can be used to create pesticides.

Strano has filed for a patent on the sensor, and the team is still working out a compression system to ensure that any molecules in the air come into contact with the tubes

This is certainly a novel approach for using the proteins found in bee venom. It seems there are a number of potential uses for the poison,

even including boosting brain functions like memory and learning. Photo credit: Flickr Via Treehugger Share Thissubscribedel. icio. usfacebookredditstumbleupontechnorati e

Snake milkers are animal care specialists who extract the venom of poisonous snakes. Snake venom while not exactly milk is nevertheless a life-giving substance (when used correctly.

The venom deadly on its own is the main ingredient in snakebite antidotes and a wide range of medicines.

Snake milkers have the job of extracting or milking the toxic substance from a snake's fangs.

The Basic Science of Poisons (Mcgraw-hill Professional 2013. Under these conditions one species of alga Anabaena flos-aquae produces a neurotoxin anatoxin-A which depolarizes and blocks acetylcholine receptors causing death in animals that drink the pond water.

And the fast-acting toxin explains the animals'strange sudden deaths. In this case the algae appeared not in ponds

Based on circumstantial evidence the most logical explanation for the elk deaths is that on their way back to the forest after feeding in the grassland the elk drank water from a trough containing toxins created by blue-green algae

The algae-produced neurotoxin is similar to curare the famous toxin found in poison-tipped arrows used by South american indian tribes.

#Poisons and Panaceas: Plants Tell History of Healing NEW YORK Modern medicine owes a great debt to botany.

and other potent medicinal plants the line between poison and panacea is often thin. Opium poppy gave rise to morphine

When he called his local poison control center and explained his story the operator told him to call plant expert Michael Balick of the New york Botanical garden.

In reality toxins can accumulate anywhere in the body particularly in fat and fatty tissue but also in proteins and bone.

The colon is surprisingly low in toxins however. As for the liver the confusion is that this organ filters toxins

and must therefore the reasoning goes be loaded with toxins. But the liver is more of a chemical-processing plant than a filter;

it breaks down toxins as they pass through. That is the liver doesn't have extra toxins by virtue of it being the body's natural toxin-neutralizer.

Wishful thinking: 6'Magic bullet'Cures That Don't Exist Another argument is that burning fat in this case on a raw vegan diet would release toxins from the body.

But fat cells don't burn up as if into ashes liberating their contents. Fats cells merely get bigger or smaller depending on the amount of fat within the cell that's used.

It is unclear how much of a toxin if any would be set free if the fat molecule it is attached to is burned.

The toxin is now free to attach to other fat molecules. If it does mobilize with other recently liberated toxins in the case of extreme starvation then the toxin could become toxic

and overwhelm the liver. In short there are no foods or herbs that can magically bind and pull toxins from your blood or organs.

The same would be true for cows or for any vegan animals that accumulate toxins in their fat;

they don't cleanse themselves with their raw plant-based diet. At best detoxification schemes (juicing fasting) can help by virtue of not placing more toxins in our body for a day or two.

And a healthful plant-rich diet with plenty of water can in general help your liver

and kidneys process and remove toxins more effectively Mcdougall said. Misconception#4: Raw veganism is healthful Healthfulness

Arsenic is classified as a poison by the National institutes of health and is considered a carcinogen by the National Toxicology Program.

#Sipping Tarantula Venom Kills Crop-Eating Insects The venom in a tarantula's fangs packs a lethal punch

But the toxic brew could also serve as an insecticide against agricultural pests that consume the venom orally a new study finds.

A component of the spider venom is especially effective against the cotton bollworm a pest that attacks crop plants.

In the last decade researchers have been investigating bioinsecticides proteins derived from natural sources such as spider venom.

The World's Creepiest Spiders In the study researchers milked venom from Australian tarantulas (Selenotypus plumipes)

When ingested by insects the poisonous chemical called orally active insecticidal peptide-1 was as toxic as the synthetic insecticide imidacloprid the group reported today (Sept. 11) in the journal PLOS ONE.

A combination of the venom peptide and synthetic insecticide was even more effective. The venom was more potent against cotton bollworms than against termites and mealworms

which eat stored grains rather than crops results showed. Venoms from other insect-eating animals such as centipedes and scorpions may also contain peptides that could be used as bioinsecticides.

Or scientists could genetically engineer insect-resistant plants or microbes that produce these toxins. The breakthrough discovery that spider toxins can have oral activity has implications not only for their use as bioinsecticides

but also for spider-venom peptides that are being considered for therapeutic use study researcher Glenn King of the Institute for Molecular Bioscience at the University of Queensland Australiaâ said in a statement.

S. plumipes is one of Australia's largest spiders but is not harmful to humans.

What Is Poisonous Gas? Updated on Friday Aug 30 at 10:15 a m. ET. Reports that the Syrian government has used poisonous gas against rebels in that country's civil insurrection have prompted the Obama administration to consider military action against the government of President Bashar al-Assad.

Though these reports have yet to be confirmed many experts say the videos and photographs from Syria showing dead and injured people would be difficult to fake.

Senior White house officials have evidence that the poison used was sarin gas the Wall street journal reports.

The Syrian government however has denied consistently all allegations of the use of poisonous gas or other chemical weapons.

Poisonous gas has a long grim history of use in warfare. In the ancient Syrian city of Dura-Europos the remains of about 20 soldiers from A d. 256 were discovered by archaeologists in 1930.

The 10 Most Outrageous Military Experiments The use of poisonous gas and other chemical weapons was banned by the Geneva Protocol following World war i sometimes referred to as the chemists'war during

Effects of nerve agents Because the alleged poisonous gas attacks in Syria are unconfirmed it can't be determined

what type of poisonous gas (if any) is being used. However Dr. Khaled al-Doumi director of a medical center near the site of the alleged attack told Al Jazeera Medically speaking the symptoms indicate that poisoning was a result of phosphorous compounds that could be caused by organic insecticides or sarin gas.

Sarin gas is a man-made lethal toxin with no color taste or odor; it can be inhaled

Mustard gas stockpiles According to the BBC Syria also has large stockpiles of mustard gas recognized as a poisonous gas since the 19th century.

Mustard gas is a relatively slow-acting toxin and symptoms of exposure may take up to 24 hours to develop.

There are a number of other chemical agents that could be used as poisonous gas from chlorine gas

Many international observers believe it could be years before the extent of poisonous gas used in Syria

#Will poisoned Mice Solve Guam's Snake Problem? In a desperate bid to reduce Guam's population of poisonous brown tree snakes officials with the U s. Department of agriculture believe they've hit on a foolproof plan:

airdropping dead mice onto the Pacific island. It gets weirder: Before the airdrop the dead mice will have stuffed their bodies with Tylenol (acetaminophen)

That will also reduce the risk that the dead mice will poison other animals. The brown tree snake a native of Australia Papua new guinea

Though poisonous the invasive specie's venom isn't lethal to humans. But the snakes have wreaked havoc on the ecosystem of Guam decimating the island's native bird population.

Just 68 snakes out of several thousand according to ABC News. The poison-mouse trick has been used before in Guam:

With no evidence of infectious diseases or deadly toxins in whale tissue samples scientists are scrambling to determine a cause of death.

It also helps flush out toxins in kidneys and prevent kidney stones. Asparagus is high in fiber with 2 grams of insoluble fiber and 1 gram of soluble fiber per cup.

They initiate detoxification by forming the basis for glutathione helps the liver process toxins. Digestion The fiber in onions promotes good digestion

but because eucalyptus leaves are laced with a toxin the koalas can eat only a limited amount before the toxin harms the animals Kearney said.

and the scientists suspected it might be the toxin. The researchers gave flies food with Truvia Pure Via pure erythritol or sucrose (table sugar.

Males have a spur on the back of their hind feet that is connected to a venom-secreting gland.

More venom is secreted during mating season leading researchers to think that the spurs and venom help males compete for mates according to the Australian Platypus Conservatory.

The venom is not life threatening to humans but it can cause severe swelling and excruciating pain.

A typical platypus is 15 inches (38 centimeters from its head to the end of its rump.

Farmers and ranchers have tried controlling the population with poisons guns and traps but the populations are still growing according to the International Union for Conservation of Nature (IUCN).

The Amazing Arachnids of the World They possess no venom glands and many species are said quite passive Eileen Hebets a biology researcher at the University of Nebraska-Lincoln who studies amblypygids.

In addition while their bite might hurt their venom is not lethal to humans. The Goliath bird-eating tarantula is big

and release poisons called mycotoxins into the food that could over time make you very sick.

The tips of the hyphae also release the mycotoxins which are released probably to ward off competitors.

So wherever the mycelia go in search of nutrients toxins may also be found. The extent of spread of the mycelium is not always visible

You re unlikely to experience any immediate symptoms from ingestion of mycotoxin-contaminated foods. Ongoing exposure increases the chances of a range of diseases including include kidney liver

Not all molds on foods will produce mycotoxins or produce them at harmful levels but without a microscope and laboratory its hard to distinguish the dangerous and harmless ones.

and producing mycotoxins. The same is true for porous foods such as bread and cakes where the hyphae can penetrate.

But exposure to toxins and to diseases also play a part based on numerous studies. Gut microbes very plausibly play a role in host resistance to these things and also in improving nutrition.

But photosynthesizing bacteria used up CO2 and produced poisonous to those bacteria oxygen (O2) that eventually filled the atmosphere.

Vitamin b12 supplements are said also to protect against the poisons in tobacco smoke. Some people use Vitamin b12 supplements to help treat male infertility sleep disorders depression inflammatory bowel disease asthma multiple sclerosis allergies and the skin condition vitiligo.

Some species in that family called cherry millipedes can release hydrogen cyanide a poisonous chemical when disturbed by predators.

because poisonous things are usually bitter. At least one study suggests that supertasters do indeed eat fewer bitter vegetables.

Cobra is the common name for a group of poisonous snakes in Africa and Southern Asia.

because they possess hoods poisonous fangs and the ability to raise the upper part of their body.

Cobras are Elapids a type of poisonous snake with hollow fangs fixed to the top jaw at the front of the mouth.

Many species have potent neurotoxic venom which attacks the nervous system of the prey leading to respiratory paralysis if untreated.

Some cobras including all spitting cobras have cytotoxic venom that attacks body tissue and causes severe pain swelling and possible necrosis (death of cells and tissue).

Spitting cobras also have the ability to shoot venom from their fangs directly into the eyes of the victim with terrifying accuracy.

Venom in the eyes can lead to blindness if not washed out well. These 18-footers are the longest of all venomous snakes.

Though there are other snakes with more potent venom the amount of neurotoxin that a king cobra can emit in one bite is enough to kill 20 people or one elephant.
