while also boosting wheat's drought tolerance and disease resistance. Though the new strain of wheat won't be available for a few years British farmers
and food manufacturers heralded the announcement. Wet weather in 2012 lowered crop yields and forced The british to import wheat for the first time in decades.
Instead the researchers relied on ancient grasses crossbreeding them with existing strains of wheat the Daily mail reports.

#Carrots & Eye Health: How the Myth Began The myth that carrots improve your eyesight may have its roots in a WORLD WAR II propaganda campaign.
These oocysts can infect pregnant women causing congenital problems in the baby such as deafness seizures eye damage and mental retardation.
The parasite also infects people with compromised immune systems such as those with HIV/AIDS. After reviewing past studies on the parasite a team of researchers believes the Toxoplasma parasite may be a significant public health problem infecting people who are otherwise healthy.
Other studies have linked even the parasite to schizophrenia depression suicidal behavior and lower school achievement in children.
The 10 Most Diabolical and Disgusting Parasites In the last five years researchers have studied how long the Toxoplasmaoocysts remain viable.
said study researcher E. Fuller Torrey a psychiatrist at Johns hopkins university Medical center in Chevy Chase Md.
and only a single one is needed to cause an infection according to past research. Other animals like sheep and cattle can also acquire the parasite by ingesting the infected cat feces.
In countries like France or Ethiopia where raw food is common the incidence of infections is much higher Torrey told Livescience.
Similarly children could acquire the infection from playing in sandboxes and gardeners could acquire it from vegetable patches
Genetic predisposition or age at the time of infection could play a role Torrey said.
which will be published in a future issue of the Journal of Pediatrics. Researchers at the University of Liverpool in England looked at 181 children between ages 8 and 11.
#Celiac disease: Symptoms & Treatment Celiac disease is an autoimmune digestive disease that affects at least 1 in 133 Americans (roughly 1 percent of the population.
People with celiac disease also called celiac sprue or gluten-sensitive enteropathy cannot eat gluten. Gluten is a protein found in foods processed from wheat and other grains.
Exposure to gluten damages the lining of the small intestine interfering with the absorption of nutrients from food and often causing abdominal pain.
and many food companies and restaurants now offer menus that cater to those with celiac disease. Studies show that men
and women of any age and race can be affected by celiac disease but is more prevalent in those of Northern European descent.
Because the disease is based genetically it is more common in those who have a first-degree relative (parent child or sibling) or second-degree relative (grandparent uncle aunt cousin niece nephew or half-sibling) with celiac disease.
There are two main genes related to celiac disease. Ninety-five percent of people with celiac disease will have the HLA-DQ2 gene
and the other 5 percent have the HLA-DQ8 gene. Genetic testing is used often to calculate the risk for celiac disease.
However having the gene means that you are simply at risk for developing disease and is not a conclusive diagnosis. Positive genetic tests should be followed up with celiac blood panels
and possibly biopsies depending on the result of the blood panels. If the genetic tests return with negative results the patient can essentially rule out celiac disease.
When a person with celiac disease consumes gluten the immune system overreacts and targets the body s small intestine.
The villi hairlike structures in the small intestine suffer shortening and flattening. This occurs in the lamina propria and crypt regions of the intestine when the patient eats specific food-grain antigens or toxic amino acid sequences.
These toxic amino acid sequences are found in wheat rye and barley. Research shows that some celiac sufferers can tolerate oats
while others cannot. There are nearly 300 symptoms related to celiac disease but the classic symptoms are diarrhea weight loss and malnutrition.
There are also latent symptoms like isolated nutrient deficiencies depression or irritability but many of those with celiac disease have no gastrointestinal symptoms.
Because there is such a wide variation of symptoms diagnosis can be difficult. On average diagnosis for each patient takes six to 10 years.
Some of the most common symptoms of celiac disease include: Some people with celiac disease exhibit no symptoms at all
and are completely in the dark about their diagnosis. Many take this to mean that
if there are no symptoms then there isn't a problem but that simply isn t true.
Celiac disease if left untreated can cause a myriad of serious life threatening problems because of its nature as an autoimmune disorder.
Patients with celiac disease who do not follow a gluten-free diet often suffer from malnutrition.
In children this can cause stunted growth delayed development and behavioral issues. For women untreated celiac disease can lead to infertility and miscarriage as well as other reproductive issues because of the malabsorption of calcium and Vitamin d.
Celiac disease can cause bone weakness and nerve damage causing constant pain. Most unnerving people with untreated celiac disease have a significantly greater risk of developing several forms of cancer including lymphoma and small bowel cancer.
Because the symptoms of celiac disease can mimic other diseases like irritable bowel syndrome and Crohn s disease the best way to diagnose celiac disease is to start with a blood test.
Currently doctors test for total Iga Iga-ttg Iga-EMA and possibly Igg/Iga-DGP or Igg-AGA.
It s important that the patient continue to consume gluten before the blood tests to properly measure the immune system s response to that diet.
If the blood tests come back positive the doctor will likely do a biopsy of the small intestine via endoscopy to confirm the diagnosis. The earlier the disease is diagnosed the easier it is for your body to heal the damage.
There is only one way to treat celiac disease: a lifelong gluten-free diet. This diet must be strict as even the smallest amount of gluten can trigger damage to the small intestines and reverse the healing process.
Full healing in children usually takes six months while full healing can take much longer for adults.
Some people who have had symptoms for an extended period of time may take longer than two years to heal
and some will never fully recover. Many advanced complications of the disease may not be reversible like infertility and severe bone loss.
However the gluten-free diet will ease many symptoms significantly once implemented. Â Removing gluten from your diet completely is a difficult transition.
Wheat rye and barley are common in many foods like bread pasta baked goods and pizza.
But even small amounts can cause a reaction and this can be found in products like candies chocolates and many snack foods.
It s also important for those with celiac disease to avoid cross-contamination in their own kitchens or at restaurants.
For example if a restaurant serves battered chicken fingers and have only one fryer everything cooked in that fryer will be contaminated with the batter.
So even French fries which do not normally contain wheat as an ingredient would not be cooked safe
As awareness of celiac disease has grown so have options for those with celiac disease. Many gluten-free alternatives are available like gluten-free bread gluten-free pasta and gluten-free baked goods.
The gluten-free food industry is booming and is expected to exceed more than $5 billion by 2015.
Relief for many celiac disease sufferers can happen almost immediately after starting the strictly gluten-free diet.
Celiac disease should not be confused with a gluten sensitivity intolerance or allergy. Though gluten sensitivity often has the same symptoms as celiac disease it does not cause the same damage
and risks that celiac disease does. Food allergies occur when a body s immune system overreacts to a food and produces Ige antibodies as a reaction producing histamines
and causing skin breathing and heart problems. This process is very different from what happens when a celiac sufferer consumes gluten.
Though they both are overreactions of the immune system food allergies are characterized often by anaphylactic reactions
and hives whereas celiac disease is characterized by the reaction in the small intestine and other listed symptoms.
Food allergy exposures can be immediately life threatening and can also be treated with an Epipen
whereas gluten exposures for celiac sufferers cannot. Living with celiac disease can be daunting and cause anxiety.
There are a number of support groups including the Celiac Sprue Association and Healthy Villi. These support groups help people with Celiac disease express their frustrations about the diagnosis share recipes and try new food items together e
#Cenozoic era: Facts About Climate, Animals & Plants The Cenozoic era which began about 65 million years ago
and continues into the present is documented the third era in the history of Earth. The current locations of the continents and their modern-day inhabitants including humans can be traced to this period.
The era began on a big down note catching the tail end of the Cretaceous-Paleogene extinction event at the close of the Cretaceous period that wiped out the remaining non-avian dinosaurs.
The term Cenozoic first spelled Kainozoic was used originally in an 1840 entry in the Penny Cyclopedia encyclopedia in an article written by British geologist John Phillips. The name is derived from the Greek phrase meaning oerecent life.
The Cenozoic era is divided into three periods: The global climate of the early portion of the Cenozoic Period was much warmer than it is today

Even after many years of scientific research and government investigation there are still many unanswered questions about the Chernobyl accident especially regarding the long-term health impacts that the massive radiation leak will have on those who were exposed.
and radiation leaks the death toll climbed as plant workers succumbed to acute radiation sickness.
By that time many were already complaining about vomiting headaches and other signs of radiation sickness.
More than 6000 cases of thyroid cancer may eventually be linked to radiation exposure in Ukraine Belarus
Surprisingly the overall rate of cancer deaths and other health effects related to Chernobyl's radiation leak is lower than was feared initially.
Today the available evidence does not strongly connect the accident to radiation-induced increases of leukemia or solid cancer other than thyroid cancer.
For example many doctors throughout Eastern europe and the Soviet union advised pregnant women to undergo abortions to avoid bearing children with birth defects
or other disorders though the actual level of radiation exposure these women experienced were too low to cause any problems.
Despite the contamination of the site and the inherent risks in operating a reactor with serious design flaws the Chernobyl nuclear plant continued operation for many years until its last reactor was shut down in December of 2000.
Plaque produces acid that damages tooth enamel causes cavities and sets the stage for periodontal or gum disease.
Just as so-called functional foods may keep your heart healthy for instance others may promote oral health according to Christine D. Wu a pediatric dentistry researcher at the University of Illinois at Chicago.
and green teas slow the growth of bacteria associated with cavities and gum disease. Researchers at the University of Illinois at Chicago found that people who rinsed their mouths with black tea for one minute 10 times a day had less plaque buildup on their teeth than people who rinsed their mouths with water.
Research published in the journal General Dentistry earlier this year reported that 12-to 15-year-olds who ate cheddar cheese had lower acid levels in their mouths than thoseâ who ate sugar-free yogurt
Some compounds in raisins also affect the growth of bacteria associated with gum disease Wu has found.

Industrial towns where rates of cancer are so high they're known as cancer villages. Compounding these problems is the Chinese government's stony silence about anything that might imperil the country's economic development including environmental regulation.
But China's increasingly restive population of 1. 3 billion people is now starting to demand government action to combat the deadly plagues of pollution
and disease that are stalking the 21st century's economic powerhouse. The 10 Most Polluted Places On earth Chinese officials however have started barely to acknowledge the problem.
In January a chemical accident leaked benzene a known cancer-causing agent into a tributary of the Huangpu River (where the dead pigs were discovered.
Last December shortly after his sister died of lung cancer at age 35 businessman Jin Zengmin from Zhejiang province offered a 200000-yuan ($32000) reward to any local environmental official who would swim in a nearby river
The slaughter of elephants for ivory the killing of rhinos for their horns and the culling of tigers for their bones (as medicine)
Cancer villages Perhaps no other issue underscores China's reckless disregard for environmental and public health more than the existence of cancer villages entire towns that have been written off as so polluted that simply living there is a cancer risk.
For years individuals and groups have waged a desperate campaign to force the government to address
or even acknowledge the high rates of stomach liver kidney and colon cancer in certain areas usually adjacent to heavy industrial complexes the BBC reports.
Many of the river's contaminants like cadmium and zinc are known to cause cancer. All the fish died even chickens
and a terrible itch He Shuncai a 34-year-old farmer from Shangba told Reuters. Last year alone six people in our village died from cancer
The report went on to state that there are some serious cases of health and social problems like the emergence of cancer villages in individual regions marking the first official admission of the problem that has plagued the country for decades.
Population growth China's one-child policy is acknowledged universally as having effectively kept the country's population in check.
The health risks associated with these kinds of purchases have not gone unnoticed: Binge drinking and alcohol-related hospitalizations have reached now epidemic proportions the Guardian reports
and the Chinese who once enjoyed a relatively healthy diet and low rates of cancer now dine on twice as much meat as Americans consuming one-quarter of the world's supply according to the Telegraph.
These consumer trends multiplied across a large and heavily populated country have a global reach that affects everything from sugar prices in Europe to climate change in Greenland:
While China's traditionally obdurate government hierarchy has seemed to value economic development at any cost including the health of its citizens
The government's recent admission that cancer villages exist shows that the environment ministry has acknowledged that pollution has led to people getting cancer environmental lawyer Wang Canfa told Agence Frence-Presse.
It shows that this issue of environmental pollution leading to health damages has drawn attention. Coupled with the public outcry over the thick blanket of toxic smog that covered Beijing earlier this year there are glimmers of hope that the Chinese people may succeed in wresting some measure of control over their environment and their lives back from government and industry leaders.
Whether they will succeed remains to be seen. Email Marc Lallanilla or follow him@Marclallanilla. Follow Livescience on Twitter@livescience. We're also on Facebook & Google+.

This in turn can lead to heart disease and heart attack. Symptoms & Causes There are really no symptoms of high cholesterol.
The doctor will be able to tell if the cholesterol levels have risen too quickly and can then help with a treatment plan.
Smoking and diabetes are also risk factors for high cholesterol according to the Mayo Clinic. Diagnosis & Tests A blood test is performed usually to test the levels of HDL and LDL cholesterol levels.
A doctor may ask you to fast for 12 hours before taking the test. HDL levels that are below 40 mg/dl (meaning 40 miligrams in a deciliter of blood)
or LDL levels that are above 200 mg/dl mean you are at risk of having high cholesterol.
It's good to aim for a LDL level that is under 130 mg/dl according to the Mayo Clinic.
However if you have other factors that put you at risk for heart disease a minimum threshold may be 100 mg/dl instead.
People who are high at risk include those who have had a heart attack or have neck arm
or leg artery blockages according to the Mayo Clinic. Â Treatments & Medications Doctors will always recommend lifestyle changes first to treat high cholesterol such as heating healthy exercising and losing weight.
However there are medications that can help lower cholesterol too. They include statins which cause your liver to remove cholesterol from your bloodstream
and arteries to reabsorb cholesterol that are known under the brand names Lipitor Lescol Altoprev Mevacor Pravachol Crestor and Zocor according to the Mayo Clinic.
Another type of medication is the bile-acid-binding resin which include the brand names Prevalite Questran Welchol and Colestid according to the Mayo Clinic.
This medication increases the liver's production of bile acids thereby reducing the amount of cholesterol in the blood.
Cholesterol absorption inhibitors like brand name Zetia limit the body's absorption of cholesterol that gets put out into the bloodstream.
These inhibitors combined with a statin known as the drug Vytorin decrease both absorption of and the production of cholesterol according to the Mayo Clinic.
There are also some natural food and supplements that may help to lower cholesterol according to the Mayo Clinic including artichokes barley garlic oat bran beta-sitosterol blond psyllium (found in Metamucil) and sitostanol.
High-Cholesterol Prevention Strategies The best way to prevent high cholesterol is the same way to treat high cholesterol leading a healthy lifestyle.
An expert in forest pathology and emergent infectious disease he contributed this article to Livescience's Expert Voices:
I am a forest pathologist and part-time mycologist working on among other projects Sudden Oak Death (SOD) an exotic forest disease that is forever changing the composition of coastal forests in Northern California and Southern Oregon.
In 2006 I decided to enlist volunteers to understand the fine-scale distribution of the disease.
At that time the cost of the operation was approximately $100000 and I was able to fund it mostly
and the validation of all samples through the lab work have generated the most extensive fine-scale map of the distribution of a forest disease in the world.
The knowledge of the fine-scale distribution of the disease is essential for predicting (and preventing) oak infections as the pathogen will infect oaks
only if they are within a couple of hundred meters of infected trees. Those results would be unimaginable from simply hiring three or four technicians per year.

Cold burns fat Brown fat cells are currently a subject of intense research as a target for anti-obesity drugs said Dr. Soren Snitker a medical researcher at the University of Maryland School of medicine

Drug development? The study is exciting because it suggests chemicals that induce brown fat could be used to fight obesity
Everybody would like to take a fat person and make him slim but that demands a high-burning capacity that BAT probably doesn't have.
Drug developers want to use similar drugs to activate this system but capsinoids themselves probably won't be used
