How Blue eyes Originated

Everyone with blue eyes alive today – from Angelina Jolie to Wayne Rooney – can trace their ancestry back to one person who probably lived about 10,000 years ago in the Black Sea region, a study has found. Scientists studying the genetics of eye colour have discovered that more than 99.5 per cent of blue-eyed people who volunteered to have their DNA analysed have the same tiny mutation in the gene that determines the colour of the iris.

 

This indicates that the mutation originated in just one person who became the ancestor of all subsequent people in the world with blue eyes, according to a study by Professor Hans Eiberg and colleagues at the University of Copenhagen.

The scientists are not sure when the mutation occurred but other evidence suggested it probably arose about 10,000 years ago when there was a rapid expansion of the human population in Europe as a result of the spread of agriculture from the Middle East.

“The mutations responsible for blue eye colour most likely originate from the north-west part of the Black Sea region, where the great agricultural migration of the northern part of Europe took place in the Neolithic periods about 6,000 to 10,000 years ago,” the researchers report in the journal Human Genetics.

Professor Eiberg said that brown is the “default” colour for human eyes which results from a build-up of the dark skin pigment, melanin. However, in northern Europe a mutation arose in a gene known as OCA2 that disrupted melanin production in the iris and caused the eye colour to become blue.

“Originally, we all had brown eyes,” said Professor Eiberg. “But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a ‘switch’ which literally turned off the ability to produce brown eyes.”

Variations in the colour of people’s eyes can be explained by the amount of melanin in the iris, but blue-eyed individuals only have a small degree of variation in the amount of melanin in their eyes, he said.

“From this we can conclude that all blue-eyed individuals are linked to the same ancestor. They have all inherited the same switch at exactly the same spot in their DNA,” said Professor Eiberg.

Men and women with blue eyes have almost exactly the same genetic sequence in the part of the DNA responsible for eye colour. However, brown-eyed people, by contrast, have a considerable amount of individual variation in that area of DNA.

Professor Eiberg said he has analysed the DNA of about 800 people with blue eyes, ranging from fair-skinned, blond-haired Scandinavians to dark-skinned, blue-eyed people living in Turkey and Jordan.

“All of them, apart from possibly one exception, had exactly the same DNA sequence in the region of the OCA2 gene. This to me indicates very strongly that there must have been a single, common ancestor of all these people,” he said.

It is not known why blue eyes spread among the population of northern Europe and southern Russia. Explanations include the suggestions that the blue eye colour either offered some advantage in the long hours of daylight in the summer, or short hours of daylight in winter, or that the trait was deemed attractive and therefore advantageous in terms of sexual selection.

Mortality Increase From Alzheimer’s Disease in the United States within the last 10 Years. Data for 2000 and 2010

Fascinating data from the Center for Disease Control.  A generation ago we could not even spell Alzheimer’s. It now looks like we are facing an avalanche of seniors losing their minds, and their lives, in later years.  You better believe that I will be looking for all preventative methods and cures for this dreaded degeneration of the brain.  I have seen what it does and it has no dignity.

Alzheimer’s disease is the sixth leading cause of death in the United States

NCHS Data Briefs Update.

In 2010, Alzheimer’s disease was the underlying cause for a total of 83,494 deaths and was classified as a contributing cause for an additional 26,488 deaths. Mortality from Alzheimer’s disease has steadily increased during the last 30 years. Alzheimer’s disease is the sixth leading cause of death in the United States and the fifth leading cause for people aged 65 years and over. An estimated 5.4 million persons in the United States have Alzheimer’s disease. The cost of health care for people with Alzheimer’s disease and other dementia was estimated to be 200 billion dollars in 2012, including 140 billion dollars in costs to Medicare and Medicaid and is expected to reach 1.1 trillion dollars in 2050.

Alzheimer’s disease mortality varies by age, sex, race, Hispanic origin, and geographic area. This report presents mortality data on Alzheimer’s disease based on data from the National Vital Statistics System from 2000 through 2010, the most recent year for which detailed data are available.

Key findings

Data from the National Vital Statistics System

  • The age-adjusted death rate from Alzheimer’s disease increased by 39 percent from 2000 through 2010 in the United States.
  • Alzheimer’s disease is the sixth leading cause of death in the United States and is the fifth leading cause among people aged 65 years and over. People aged 85 years and over have a 5.4 times greater risk of dying from Alzheimer’s disease than people aged 75–84 years.
  • The risk of dying from Alzheimer’s disease is 26 percent higher among the non-Hispanic white population than among the non-Hispanic black population, whereas the Hispanic population has a 30 percent lower risk than the non-Hispanic white population.
  • In 2010, among all states and the District of Columbia, 31 states showed death rates from Alzheimer’s disease that were above the national rate (25.1).

Keywords: dementia, National Vital Statistics System, death rate, aging

Alzheimer’s disease mortality increased compared with selected major causes of death.

Grounded

“Grounded” is an independent feature film based documentary about what is considered by many authorities to be “The Greatest Health RE-discovery of All Time.” – the concept was tested on the people of Haines, Alaska (population 1,700). 

The surface of the Earth holds subtle health-boosting energy. The documentary goes to show that this amazing phenomenon, of connecting into the earth, can transform the life of people who have been struggling with health issues like chronic pain, and one man who had been wheelchair-bound for decades is able to walk again. Even plants are drastically impacted when they have been taken away from the Earth’s natural energy.

East Coast Tsunami: If It Happens, MILLIONS Of Americans Could Die

Could you imagine what would happen if a tsunami hundreds of feet high slammed into the east coast of the United States at several hundred miles an hour?  Just because it has never happened during any of our lifetimes does not mean that it can’t happen.  In fact, scientists tell us that there is a very good chance that it will happen someday.  And if it does happen, there is a very good chance that the number of dead Americans could be in the millions.  Even though there are “Tsunami Hazard Zone” signs on Florida beaches to remind us of this potential threat, we have built giant cities right along the edge of the water all along the Atlantic coast.  Today, an astounding 39 percent of all Americans live in counties that directly border a shoreline.  The potential…

Say goodbye to Ringling elephants walking through the streets


Originally posted on Fusion:

Animal activists everywhere can rejoice. The Ringling Bros. and Barnum & Bailey Circus announced plans to phase out the use of elephants in their acts. By 2018, the historic circus will no longer feature the animals, which also means an official end to the annual New York Elephant Walk –a mainstay of the circus’ arrival in town.

According to Google Maps, the elephant walk from Queens, through the Midtown Tunnel, to Madison Square Garden –the circus’ usual New York venue– is about 2 miles long and would take a human 40 minutes to walk.

Here’s a look at some of those New York City moments we’ll be happy to say good bye to.

The elephants were paraded through New York for 30 years.

This map shows why Ringling Bros. is phasing out its elephants


Originally posted on Fusion:

Ringling Bros. and Barnum & Bailey Circus didn’t really get a conscience.

Instead, they started to get worried about getting poor.

This morning the largest circus company in the U.S. told AP reporter Tamara Lush that it would phase out all elephants of its shows by 2018.

But it wasn’t necessarily because of public outcry over the use of bullhooks, which animal-rights groups say is a form of torture; or the generally questionable decision to force exotic animals to perform.

“We’re not reacting to our critics,” Ringling parent company president Kenneth Feld told Lush.

Instead, he said, cities and counties have begun passing what he referred to as “anti-circus” and “anti-elephant” ordinances, and the cost of fighting legislation in each jurisdiction was beginning to mount.

“All of the resources used to fight these things can be put towards the elephants,” he said.

The most recent such ordinance came just a…

Ringling Bros. Circus eliminating elephant acts amid public concerns


Originally posted on Global News:

POLK CITY, Fla. – The Ringling Bros. and Barnum & Bailey Circus is ending its iconic elephant acts.

The circus’ parent company, Feld Entertainment, told The Associated Press exclusively that the acts will be phased out by 2018. Growing public concern about how the animals are treated led to the decision.

The circus plans to phase out elephant acts by 2018. Feld’s 43 elephants will live at the company’s 200-acre Center for Elephant Conservation in central Florida. Twenty-nine animals are already there, and the other 14 will arrive as they are phased out from the circus.

Elephant acts have been showcased by Ringling for more than a century and have often been featured in its posters.

The decision is being announced Thursday.

A Search Warrant For Your Brain?

(Inside Science) — Brain imaging can already pull bits of information from the minds of willing volunteers in laboratories. What happens when police or lawyers want to use it to pry a key fact from the mind of an unwilling person?

Will your brain be protected under the Fourth Amendment from unreasonable search and seizure?

Or will your brain have a Fifth Amendment right against self-incrimination?

“These are issues the United States Supreme Court is going to have to resolve,” said Nita Farahany, a professor of law and philosophy at Duke University in Durham, North Carolina, who specializes in bioethical issues.

Those legal choices are likely decades away, in part because the exacting, often finicky process of functional magnetic resonance imaging (fMRI) could be thwarted if a reluctant person so much as swallowed at the wrong time. Also, a brain exam couldn’t be admitted in court unless it worked…
