Because different foods contain different ratios of heavy and light isotopes the team was able to pinpoint the diets of the ancient people.
Isotope analysis also revealed the latter group subsisted on a diet of mainly freshwater fish while the farmers ate more domesticated animals.
and loss of major freshwater sources that they rely on for drinking water. Anchorage the state's most populated city relies entirely on the retreating Eklutna Glacier for its drinking water.
Still glacial retreat does offer an interesting opportunity to investigate well-preserved remnants of an ancient world.

A number of artifacts were unearthed during the excavation including wine jars an inkwell tin and bronze jugs stacks of Syrian-Palestinian glass bowls and Ephesian lamps.
No doubt the explosion of agricultural activity in the first century and the increased wealth that resulted from the wine
The region around Petra not only grew enough food to meet its own needs but also would have been able to provide olives olive oil grapes and wine for trade.
This robust agricultural production would have made the region a valuable asset for supplying Roman forces on the empire's eastern frontier.
and leading to other shortages in animal feed including hay and grasses. Those price spikes in turn are prompting increases in the retail prices of beef pork poultry and dairy products.
More importantly the threat posed by drought could become even greater as the planet heats up especially in parts of the United states
This also will result in less water for drinking less water for agriculture and less water for recreation.

Dementia Contrary to previous research a diet rich in antioxidants may not reduce a person s risk for stroke
Participants answered questions about how often they ate certain foods and their responses were used to calculate the total level of antioxidants in their diets.
Fourteen years later about 600 people had developed dementia and 600 had suffered a stroke. People who reported diets high in antioxidants were
just as likely to develop dementia or have a stroke during the study period as individuals who consumed diets that were low in antioxidants.
 Interestingly previous studies that used information from this same group of people found a link between consumption of Vitamin e and a lower risk of dementia and between consumption of Vitamin c and a lower risk of stroke.
While the new study looked at total antioxidant levels regardless of the food source it may be that the kind of food providing the antioxidants matters said study researcher Elizabeth Devore of the Harvard Medical school in Boston.
In the current study the difference between a diet high in antioxidants and a diet low in antioxidants was linked primarily to the amount of coffee
and tea that people drank. These beverages contain antioxidants called flavonoids. However if people get most of their antioxidants from fruits vegetables
and nuts the effect on dementia and stroke risk might be said different Devore. For instance a study published last year found that women who ate a lot of citrus fruits such as oranges
Right now the U s. House of representatives and the U s. Senate are seeking to close an agreement on a comprehensive farm bill crucial to the future of food stamps farm subsidies
which would help American families eat more healthily through targeted grants to local and regional food projects.
Debbie Stabenow Democrat of Michigan chair of the Senate Agriculture Committee has a huge challenge in trying to come to terms with her House counterparts who'd like to cut the food stamp program alone by $40 billon.
But his amendment is so broad it also guts efforts by states to protect their citizens from food-borne illnesses.
Also snuck into the bill are a couple of provisions that would allow big agricultural livestock operations to keep even basic information about their businesses even their location and phone numbers from public disclosure.
The provisions were prompted by the EPA's inadvertent disclosure of the private information of thousands of farmers in response to a request from three environmental groups about confined animal feeding operations (CAFOS.

Risks and regret In the second experiment 24 chimps and 13 bonobos were shown a small pile of food under an overturned bowl
The foods varied in deliciousness at least from a primate perspective. The researchers determined that chimps preferred bread and bananas above all else while bonobos loved apples and bananas.
Chimps were excited least by papaya and cucumber while bonobos cared least about peanuts and lettuce.
The visible bowl contained middle-of-the-road foods for both species: peanuts for chimpanzees and papaya for bonobos.
The apes could chose this so-so food or decide to take a risk and pick the unknown food under the second bowl
which might be a delicious banana or a boring scrap of lettuce. The results revealed that chimpanzees were bigger risk-takers than the bonobos.
Chimps picked the unknown risky option 65 percent of the time compared with 39 percent of the time for bonobos.
Again both species got irritated when those risky choices failed to pay off with a favorite food.
They banged vocalized and scratched. The apes even showed a behavior that looked a bit like regret.
and finding a disliked food the animals frequently tried to change their choice to the other bowl.
In the wild chimpanzees tend to live in areas where food is seasonal and hard to find
For example bonobos who tried hardest to switch their choice after an unwanted outcome in the food bowl experiment were also the least likely to take risks in the first place.
A new study reviewed the diets of crocodiles and showed that 13 of 18 species ate fruit of some sort and a wide variety of plants.
So there is some chance that these crocodiles are indirect eaters of fruit who feast on fruit-eating animals.
But direct observations (see video) have been made many times to believe that they might actually like eating fruits.
Perhaps it is similar to why dinosaurs consumed stones (gastroliths) to help with grinding food in their stomachs
If meat was ever in short supply they had the capacity to diversify and track down other food sources from vegetation and grasses.
The study reveals something interesting about the way scientists might operate. Crocodiles are obligate carnivores their primary diet is meat
and as such fruits are classed often as anomalous food items when found in their stomach and not considered in a physiological context.
This mainstream view may have led to the ignorance that feeding on fruits could help their diet and energy balances.
That the review study picked up so many independent instances of crocodiles feeding on fruit and having ingested seeds is solid evidence for this.
      Recently vets and dog owners noted that eating grapes
which to make the claim that dogs for example are emotionally more complex than pigs or other food animals.
and chickens display empathy and are very smart and emotional they are protected not by the United State's Federal Animal Welfare Act.
Research shows that many people who eat meat are concerned indeed with the level of intelligence of the animals who find themselves in their meal plan
and suffering such as that endured by food animals and the most usual answer is marked no with surprise and incredulity about why
For example David Warner of the National Pork Producers Council claims While animals raised for food do have a certain degree of intelligence Farm Sanctuary is trying to humanize them to advance their vegan agenda an end to meat consumption.
While seeking a vegetarian or vegan world or a world in which meat consumption is reduced drastically is among the goals of many people claiming that other animals are intelligent
or have rich and deep emotional lives is not an attempt to humanize them. Indeed when we pay attention to solid evolutionary theory namely Charles darwin's ideas about evolutionary continuity we see that we humans are not the only smart sentient and emotional beings.
When The Cambridge Declaration was made public there was a lot of pomp champagne and media coverage. There is no need to have this fanfare for A Universal Declaration on Animal Sentience.
The Someone Project is simply raising consciousness about who food animals are and stays well within the bounds of available scientific evidence.
Furthermore no one I know who favors a vegetarian or vegan diet believes that food animals will roam free
if they're not eaten. The way in which we could fulfill our ethical obligations to these animals would be to stop factory farming right now
and suffering non-animal meals will likely become more common. Pardon our obliviousness to the pain
A 2006 study from the Journal of Interpersonal Violence revealed that owners of vicious dogs were significantly more likely to have criminal convictions for aggressive crimes drugs alcohol domestic violence crimes involving children and firearms.
#Arsenic in Rice Not a Risk Over Short term, FDA Finds Levels of arsenic in rice appear to be too low to pose health risks over the short term the Food
people should eat a balanced diet in order to minimize the health effects that could come from eating too much of any one food.
Consumers should vary their grains-for instance by eating wheat barley or oats as well as rice. Parents can also consider alternatives to rice-based foods as their child's first solid foods the FDA said.
Research suggests that rice cereal has no advantage over other grains as an infant's first food.
Earlier this year the FDA set a limit for the first time on the amount of arsenic allowed in apple juice at 10 parts per billion (ppb)
which is the same amount allowed in drinking water. Arsenic can be found in food because it occurs naturally in the environment.
Human activity such as use of certain pesticides can also add arsenic to the environment. Because rice is grown in water
and takes in more arsenic it has higher levels than other foods said Suzanne C. Fitzpatrick the senior adviser for toxicology in FDA's Center for Food safety and Applied Nutrition.
A study published in 2011 found that people who eat more rice have higher levels of arsenic in their systems.
In that study researchers found that eating just over a half-cup of cooked rice is equivalent to drinking 34 ounces (one liter) of water containing the maximum amount of arsenic allowed by the federal limit.
Just how much rice you'd need to consume for it to affect your health is unknown.
NRDC is pushing the U s. Food and Drug Administration (FDA) to do the right thing and stop the use of antibiotics in animals that are not sick.

The team counted the number of chicks demanding regurgitated meals from their parents to gauge the total colony size
because the adults were off fishing for food. The good weather this season gave us the opportunity this season to spend a bit more of time counting individual emperor penguins said Alain Hubert the expedition leader
and tend their eggs. After winter ends parents make trips to the sea to deliver meals to their chicks.
 Hubert and field guide Christophe Berclaz had to pick their way down a 130-foot-tall (40 meters) ice cliff to find the waddling groups of penguins.
Pesky penguins Seeing the fuzzy penguin chicks demand a vomited-up meal was Hubert's favorite part of the few hours spent at the massive colony.
#Bees Get a Buzz from Flowers'Electrical Fields Everyone knows that bees buzz around flowers in their quest for nectar.
And scientists have known for years that bees'flapping wings create a positive electrical charge of up to 200 volts as they flit from flower to flower according to a news release.
The bees depend on flowers for nectar which they use to produce honey and flowers need bees to help pollinate other flowers.
whose nectar has just been taken by another insect. The last thing a flower wants is to attract a bee
and then fail to provide nectar said Daniel Robert co-author of the study in a statement.
So flowers the researchers confirmed emit a different electrical signal after their nectar has been harvested. They found that petunias became slightly more positively charged after a bee visited them according to Scientificamerican.
Other scientists are excited about the possible implications this research may have for other nectar-gathering insects such as hoverflies and moths.
The results show that women who ate high amounts of compounds called anthocyanins most commonly through eating strawberries
In addition while strawberries and blueberries were the main sources ofâ anthocyanins they are found in other foods as well including blackberries eggplant and grapes.
The American Heart Association (AHA) says eating a variety of foods is the best way to get proper amounts of the nutrients we need.
Berries can be part of a balanced diet that includes other fruits as well as vegetables and whole grains the AHA says.
The study involved 93600 American women ages 25 to 42 who answered questions about their diet every four years for 18 years.
The results held even after the researchers took into account other factors that could influence the risk of heart attack including  blood pressure body mass index exercise smoking habits and alcohol intake.
Dr. Andrew Freeman a cardiologist at the National Jewish Health Center  hospital in Denver who was involved not in the study suspects that people who had diets rich in anthocyanins also tended to live a more healthy lifestyle overall
but corn syrup is cheaper so most beekeepers feed bees artificial sweeteners Evans said. On the Hunt:
Honeybee Scouts Find Food To see whether honey provided any benefit to the bees May Berenbaum a researcher at the University of Illinois at Urbana-Champaign
The researchers then took those chemicals added them to bee candy a combination of sucrose and powdered sugar and fed them to 15 worker bees.
The findings suggest that honey isn't just providing bees with a quick source of fast food
P-Coumaric acid may ï nd use as an additive to honey substitutes to allow beekeepers to maintain colonies during food shortages without compromising the ability of their bees to defend themselves against the pesticides
But scientists should try supplementing the corn syrup with these compounds and hoping that replaces the good stuff in the honey Evans told Livescience.

#Bizarre Egg-Burying Birds Hatch at Bronx Zoo Three maleo chicks have been hatched at the Wildlife Conservation Society's (WCS) Bronx Zoo in New york where keepers recreated the conditions of the birds
While most birds sit on their eggs to keep their unhatched young warm maleos bury their large eggs in underground nests letting heat from geothermal sources the sun
so that the birds can find a warm spot to bury their eggs. Surveillance cameras allow keepers to watch the nesting areas closely
so that when an egg is laid it can be dug out of the sand immediately and moved to an incubation room where it hatches after about 70 days.
In Sulawesi the birds'wild population is shrinking due to humans'unsustainable harvesting of their eggs and predation by invasive species according to WCS officials.

#Breast Milk Flavored Lollipops Make Debut If you want to know what breast milk tastes like
but are prevented by basic human decency from asking the lactating women in your life for a favor then a candy company in Austin Texas has got a deal for you:
breast milk lollipops. The lollipops contain no actual breast milk (in fact they're vegan) but contain a candified version of breast milk's flavor apparently based on the milk of real mothers who volunteered to help company Lollyphile develop the new product.
We felt it was our responsibility to find out just what this flavor was that could turn a screaming furious infant into a placid contented one the lollipop product page reads.
Surely the flavor must be heavenly yes? The lollipops will no doubt raise some eyebrows but other companies have taken breast milk curiosity even further.
In London in 2011 an ice cream shop debuted a flavor made with the real deal.
Also that year a graduate student at New york University created an art installation called the Lady Cheese Shop with cheese made from human breast milk.
And in 2010 a Manhattan chef offered a cheese made from his wife's breast milk though the New york Health Department quickly shut that experiment down.

#Bureaucracy, Meat Production Crucial To Building Egypt's Pyramids (ISNS)--Of the Seven Wonders of the World only one remains standing:
They were young males who ate exceptionally good food and had good medical care and were working for the good of society Redding said.
The gangs were named Redding said such as the Drunkards of Menkaure. Feeding and tending the mass of workers required a bureaucracy of amazing efficiency.
The Egyptians were obsessed almost with keeping records so there is considerable evidence on papyrus on how much bread they ate
but there is very little information that survived on the quantities of meat and the infrastructure that provided the food
which is where Redding's research comes in. Redding started by calculating  the calories
what is found in two Mcdonald's quarter pounders with cheese. If half the workers'protein came from meat each worker probably ate almost  six pounds of meat each week.
 He assumed half the protein came from meat some from Nile fish. Then he looked at the breeds of cattle found in ancient Egypt
and how much meat one could get from each animal to figure out how many animals would be required to provide the protein.
He said the 10000 workers at the site he studied in Giza consumed 105 cattle and 368 sheep or goats every 10 days.
and where to provide the food the workers needed a complex system modern societies need computers to organize.
Food was prepared in central kitchens and distributed. The higher up the administrative chain a person was the better the food.
They started off from the very beginning as bureaucratic society and it was said very hierarchical Egyptologist Jennifer Hellum of the University of Auckland in New zealand.
