Fish Oil May Help Preserve Brain Cells, Study Suggests
Women with high blood levels of fish oils have larger brain volumes then those with lower levels, suggesting the oils may delay the normal loss of brain cells due to aging, research found.
Those who raised their levels of two major omega-3 fatty acids by eating fish or taking supplements had larger total brain volume than those who didn’t, according to research posted online today by the journal Neurology.
As people age, their brains get smaller but the shrinkage is accelerated in those with dementia or Alzheimer’s disease, the authors said. While today’s findings suggest that larger brain volumes equal a one- to two-year delay in the normal loss of brain cells, more studies are needed to look at what that means for memory, said James Pottala, the lead study author.
“Omega-3s are building blocks for brain cell membranes” said Pottala, assistant professor of internal medicine at the University of South Dakota in Sioux Falls and principal biostatistician at Health Diagnostic Laboratory Inc. in Richmond, Virginia, in a Jan. 20 e-mail. If achieving certain omega-3 levels “can prevent or delay dementia, that would have huge mental health benefits, especially since levels can be safely and inexpensively raised through diet and supplementation.”
More than 5 million people in the U.S. have Alzheimer’s disease, a number projected to triple by 2050, according to the Alzheimer’s Association. There is no treatment for the mind-debilitating disease. The only drugs approved for the condition ease symptoms for a few months while the disease continues to worsen.
Researchers looked at 1,111 post-menopausal women from the Women’s Health Initiative Memory Study. During that trial, women had their red blood cell levels tested for eicosapentaenoic acid, or EPA, and docosahexaenoic acid, or DHA, two major fish-derived omega-3 fatty acids, Pottala said. Eight years later, MRI scans were taken to measure their brain volume when they were an average age of 78 years.
They found that those whose omega-3 fatty acid levels were twice as high, 7.5 percent, had 0.7 percent larger brain volume. Those with the higher levels also had a 2.7 percent larger volume in the hippocampus area of the brain, which plays an important part in memory and can begin to atrophy in Alzheimer’s disease before symptoms even appear.
While the study didn’t measure how much fish or supplements the women consumed, previous research showed that healthy men and women eating non-fried oily fish like tuna, salmon or herring twice a week and taking fish oil supplements had a mean red blood cell level of EPA and DHA of 7.5 percent, Pottala said.
The brain uses DHA to make anti-inflammatory compounds that may help prevent cell death. Also the brain cell membranes are made up of DHA and insufficient amounts may cause the brain matter to decline over time, he said.
More studies are needed looking at men and women at risk for dementia and whether increasing their fish oil dose until their red blood cell levels were more than 8 percent benefited them, Pottala said.
“Thou shall have balls & not business ideas”
And 9 more commandments for startups from Indian entrepreneur, angel investor Vishal Gondal that will lead the “path to the promised land”
(Called ‘India’s King of Gaming’, Vishal Gondal is the Founder and CEO of India Games. He is considered among the among the top 25 powerful people in the Indian digital business. Erstwhile, he was the Managing Director of DisneyUTV Digital.He has received no formal education in computers and is a commerce dropout.Gondal shared his 10 commandments for startups)
We present to you the commandments…
Thou shall have balls & not business plans
Ideas are dime a dozen. To be an entrepreneur you don’t need business plans but the courage and conviction to break through the initial challenges and bring your ideas to life.
Thou shall develop relationships & not transactions
Entrepreneurs should go out, meet people and invest in building long-term relationships. Those who can’t help you today may prove to be valuable tomorrow. Don’t be transactional about it; make lifelong friends!
Thou shall focus on real pain-points
India is the land of opportunity because it has tonnes of problems for entrepreneurs to solve. Instead of aping solutions from the West, we should look at solving local problems – something not many entrepreneurs are doing today.
Thou shall be among the top 2
It’s imperative that you be No. 1 or No. 2 nationally or internationally in your defined sector to ensure you create a larger market for yourself. There is no point in becoming the nth player in an already competitive marketplace which has established leaders.
Thou shall focus on 20 per cent
As an entrepreneur, you must focus on the 20% that gives you 80% impact. Entrepreneurs tend to waste their time and effort in a number of non-productive activities just to be everywhere. This should be avoided at all costs.
Thou shall avoid MBAs & spreadsheet makers
The education system is designed to train students to fill up competencies required to work in large organisations. Startups are meant to disrupt and are run by talking to people and constantly taking feedback from the ground. The mindset required to excel at a startup is very different from one that is required in a large company where there is time to invest in building year by year projections.
Thou shall celebrate failures & enjoy your journey
As an entrepreneur, you will have many moments of failure. Organisations where failing is not okay tend to become bureaucratic. As a startup, you should build a culture which celebrates failure and people have the independence to experiment and execute new ideas without worrying too much about failure.
Thou shall not want to sell
Don’t build your company with the intention to sell. You can’t build a great startup by dreaming about selling it someday. As an entrepreneur, your startup becomes the core of your life and you have to nurture it like your own baby.
Thou shall be fit
As an entrepreneur, one tends to put their health on the backseat but there is no point in building a billion-dollar company and having boiled vegetables with a IV attached to you. If you aren’t fit both, in mind and body, you cannot operate a company.
Thou shall win with… Passion
As a startup you will have a small set of people who won’t always have the best skills or resources at their disposal. In this case, the only thing you can motivate them with, is PASSION. As an entrepreneur you need to make your team believe that this is their chance to do something remarkable with their career!
Wisconsin’s Ice Caves Are Open For The First Time In Years, And They Look Incredible.
The 21-island park located off the coast of the northern tip of Wisconsin is a well-known summer kayaking destination that attracts visitors with colorful, winding caves and rock formations that protrude and dip along the water line…..In the winter, the seashore takes on an entirely different quality. As frigid weather takes its toll on the Midwest, massive stalagmites and stalactites form along the islands’ striated geology. Inside the caves, lake water freezes into smooth, icy floors that are as clear as a sheet of glass.
Visitors can reach the caves by walking about a mile across the frozen surface of the lake — when the ice is thick enough, that is….Park officials monitor the ice conditions carefully, and the last time the ice was thick enough to venture safely out onto the frozen lake was in 2009. Luckily, after the past several weeks of Arctic-like weather, Lake Superior is now iced over enough to allow safe passage from the mainland to the caves.
‘Facts’ About History You Thought Were True, But Definitely Aren’t.
It’s almost as if you should relearn everything you know about history.
*[Takes deep breath]* Vikings didn’t have have horns on their helmets, iron maidens aren’t real, Columbus didn’t prove the world is round, Napoleon wasn’t short, Paul Revere didn’t shout “the British are coming,” Isaac Newton wasn’t hit by an apple, Walt Disney didn’t draw Mickey Mouse, Nero didn’t fiddle over a burning Rome and “Et tu, Brute?” doesn’t have the historical significance you think it does. *[Exhales]*
And that’s just the beginning. The stories below have become so persistently ingrained in our popular culture that we still consider them “facts” worthy of the history books. They aren’t.
So let’s set these stories straight…
1. The “story of Hamlet” was created by Shakespeare.
The plot of a vengeful prince planning retribution for the murder of his father the king, by his uncle, is at the center of an old Indo-European legend.
Around 1200 AD, the Scandinavian author Saxo Grammaticus even popularized the story in a work called, “Vita Amlethi,” or “The Life of Amleth.”
While the prince in Grammaticus’ story is named Amleth, Prince of Denmark, Shakespeare’s main character is Hamlet, Prince of Denmark. In Grammaticus’ version, too, the tormented prince fakes madness, is angered by his mother’s quick marriage to the new king, and kills a secret spy.
2. George Washington Carver invented peanut butter
Although finding hundreds of new uses for the peanut and greatly aiding the farming economy of the American South, Carver didn’t invent peanut butter, despite popular belief.
Peanut butter has actually been around since about 950 B.C., as the Incas in South America mashed their peanuts into a paste. But even in contemporary times, the first patent for a peanut butter-like substance was registered in 1884, when Carver was only about twenty years old. In his 1943 New York Times obituary, no mention of inventing peanut butter appears, though the publication lists peanut-based developments “including milk, ink, flour, breakfast foods, wood stains, face creams and, latterly, a medicinal peanut oil which was found helpful in the treatment of infantile paralysis.” Carver never patented his products as he believed they were a gift from God.
Dr. John Harvey Kellogg is credited with the first patent related to “peanut butter,” but most suspect that the true inventor of the delicious spread we’ve come to knowwill remain a mystery.
3. Ninjas wore all black costumes.
If anything, ninjas would have worn dark blue, as the night isn’t actually pitch black.
The thing is, it would very rarely make sense for ninjas to have an “assassin” costume so ridiculously different from a normal wardrobe. No matter how many shadows you can sneak through, at some point you’d need to get close enough to the target to make the kill, and wearing an outlandish outfit that people would clearly identify you as “assassin” seems idiotic. But even the idea of ninjas regularly performing sneaky assassinations might be fairly skewed and overblown.
The Ninja Museum of Iga-ryū, a historical school of ninjutsu in Japan, claims the popular idea of what ninjas do and look like is “a mistaken image of the ninja introduced by movies and comic books.” Ninjas who would swing their swords around in fights were considered the “lowest of the ninja,” as using intellect and acts of espionage was typically the goal.
4. Lady Godiva rode naked through the streets on a horse.
You probably now know her best from chocolate boxes, but according to legend, Lady Godiva wanted her husband to abolish taxes on the citizens of Coventry, England, so she rode through the town naked on a horse. How did that make sense? In a deal she made with her husband Leofric, Earl of Mercia, he would only grant her wish if Godiva made the now-famous nude ride. She obliged, and the town’s taxes were abolished to the historic delight of the citizens of Coventry and generations to come.
There are a few reasons to question this tale, beyond its apparent outlandishness. First of all, it didn’t start sprouting up until centuries after Godiva’s death. The original version came from a monk from a monastery Godiva had originally funded. Furthermore, Coventry probably didn’t even pay taxes back then.
5. Vincent Van Gogh sliced off his ear.
Although many people think that Van Gogh cut off his whole ear, it was actually just a portion of the left earlobe that was removed. Furthermore, there’s a compelling argument that Van Gogh wasn’t the one who cut off the earlobe at all.
At the time of this incident, Van Gogh was living with his friend, French artist Paul Gauguin, with whom he had a tumultuous and often violent relationship. Gauguin was an expert fencer and the earlobe came off right after the two had a massive quarrel. The two officially asserted that Van Gogh had cut it off himself, but this could have been a decision by the artists to cover up the true shame and guilt of the encounter, especially when considering Van Gogh claimed in interviews that he had no recollection of the night. Although Van Gogh was also notorious for being mentally unstable, which could lend potential credibility to the tale, he did later write to his brother, “Luckily Gauguin … is not yet armed with machine guns and other dangerous war weapons.”
If you still want to hold on to some part of the legend, according to a report in Le Petit Journal just three days after the incident, Van Gogh apparently did actually gift the earlobe to a prostitute.
6. King Henry VIII was fat and villainous during his whole reign.
The later years of King Henry VIII — the ones that involved many wives and beheadings — seem to wholly overshadow those of a once relatively kind and generous ruler.
Despite the common imagery of Henry as a fat, bearded despot, the king actually took the throne at the age of 18 and was originally revered by subjects. They even called him “Bluff King Hal.” Few people seem to know that right before the end of his marriage with Anne Boleyn, the king was still considered “sporty and generous.”
Unfortunately, things started to fall apart when Henry was beset by persistent medical ailments like leg ulcers, which caused him to grow fatter and angrier as the years passed.
However, things also took a serious turn for the worse when Henry was thrown from his horse in a horrific jousting accident. The animal ended falling on top of him, leaving the royal unconscious for two hours. He reportedly experienced a downturn in mental capacities as well as extreme leg pain for the rest of his life. Boleyn miscarried a male child after learning of Henry’s accident and later that year the king had her executed, starting a long, infamous history of villainy.
7. Benjamin Franklin proposed the turkey should be our national bird over the bald eagle.
The only recorded account of Franklin talking about turkeys and eagles is in a private letter to his daughter about a military group called the Society of the Cincinnati, whose eagle seal he criticized for being inaccurate and looking more like a turkey. It is true that in this letter he also said that he wished the bald eagle wasn’t the national seal, but his “preference” for the turkey was only because he thought that the SoC seal looked more like the bird that would eventually come to symbolize Thanksgiving.
Franklin actually did propose a different national seal in one of the early planning stages, but instead of any bird, he brought forth a more biblical symbol:
Moses standing on the Shore, extending his Hand over the Sea, thereby causing the same to overwhelm Pharaoh who is sitting in an open Chariot, a Crown on his Head and a Sword in his Hand. Rays from a Pillar of Fire in the Clouds, reaching to Moses, to express that he acts by Command of the Deity. ‘Motto – Rebellion to Tyrants is Obedience to God.’
This proposal didn’t catch on and subsequent planning committees ended up choosing the bald eagle.
8. Einstein was a terrible student and failed mathematics.
Albert Einstein actually crushed his report cards. His reputation for being a notoriously terrible student? That came from his habit of talking back to his teachers when he felt they were acting too authoritarian.
Einstein’s mother once wrote in a letter to his grandmother, “Yesterday Albert received his grades, he was again number one, and his report card was brilliant.”…..And he definitely never failed mathematics, as in his own words, “Before I was fifteen I had mastered differential and integral calculus.”
9. Marie Antoinette said, “Let them eat cake.”
The first known report of French Queen Marie Antoinette having uttered the now-infamous words, “Let them eat cake,” didn’t surface until many years after her death. The quote is now widely considered to be a mis-attribution.
