Bezos Says Artificial Intelligence to Fuel Amazon’s Success – Bloomberg

Posted: at 11:49 pm

Amazon.com Inc. is embracing artificial intelligence to deliver goods more quickly, enhance its voice-activated Alexa assistant and create new tools sold to others through its cloud-computing division, Chief Executive Officer Jeff Bezos said in his annual shareholder letter.

Changes ushered in by artificial intelligence and machine learning will help the companies that embrace them and put up barriers for those who dont, the worlds second-richest man wrote in a 1,700-word letter released Wednesday.

Bezos repeated familiar themes, such as the need to operate a business like its always Day 1 to keep a startup mentality and the ability to act quickly on limited information to stay ahead, what he calls high-velocity decision making. His emphasis on artificial intelligence and machine learning was the most concrete indication of areas in which the e-commerce giant will continue to invest.

Machine learning is the science of getting computers to act without being programmed, and is used in autonomous cars, speech-recognition and internet search engines. The technology has influenced high-profile projects at Amazon such as drone delivery, its popular Echo voice-activated speaker and the new cashier-less Amazon Go convenience store unveiled late last year in Seattle, Bezos wrote.

Exclusive insights on technology around the world.

Get Fully Charged, from Bloomberg Technology.

But much of what we do with machine learning happens beneath the surface, he wrote. Machine learning drives our algorithms for demand forecasting, product search ranking, product and deals recommendations, merchandising placements, fraud detection, translations, and much more. Though less visible, much of the impact of machine learning will be of this type -- quietly but meaningfully improving core operations.

Amazon Web Services, the companys cloud-computing division, will offer affordable tools so clients can incorporate artificial intelligence and machine learning into their own operations. Such tools have already been used by to detect diseases and increase crop yields, Bezos wrote.

Watch this space, Bezos said. Much more to come.

Can NATO Weaponize Memes? – Foreign Policy (blog)

Posted: at 11:48 pm

Good news. NATO is no longer obsolete, according to President Donald Trump. On Wednesday, during his meeting with NATO Secretary General Jens Stoltenberg, Trump touted an alliance he once bashed because, after fifteen-odd years of alliance operations against the Taliban and al Qaeda in Afghanistan, the former reality television host just realized now they fight terrorism.

But if the most powerful political-military alliance has the real battlefield on lockdown, some worry its floundering in the battlefield of the internet, where ideas go to clash, Kremlin trolls go to spread half-truths, and ISIS goes to recruit foreign fighters.

The answer, some experts argue, lies in memes those strange jokes and references that come out of the internets woodworks from seemingly nowhere, and seem to end up everywhere at once. A small contingent of academics and experts want NATO to get in on the action to confront pro-Russian, anti-NATO trolls, or to push back against internet jihadists in the cyber space.

Its time to embrace memetic warfare, wrote Jeff Giesea, a widely-known social media and tech guru, in an article in 2015. Trolling, it might be said, is the social media equivalent of guerrilla warfare, and memes are its currency of propaganda. Giesea wasnt writing in Wired orTechCrunch, but rather in Defence Strategic Communications, the journal of NATO Strategic Communications Center of Excellence (or Stratcom COE, because nothings complete without an onerous acronym).

Daesh is conducting memetic warfare. The Kremlin is doing it. Its inexpensive. The capabilities exist. Why arent we trying it? Giesea asked.

Its a question many military minds have been asking for years. A Marine Corps Major, Michael B. Prosser advocated for the U.S. military to develop a Meme Warfare Center (MWC) in his 2006 study, MemeticsA Growth Industry in U.S. Military Operations (abstract here).

Five years later, a specialized Pentagon unit, the Defense Advanced Research Projects Agency (DARPA) funded a study on Military Memetics, one of several related research programs into what it calls a subset of neuro-cognitive warfare. It argued the war of ideas was fundamental, especially when it comes to fighting terrorists, and the key characteristics of a military meme is that it be information that propagates, has impact, and persists. Like dancing cat videos, in other words, but with sharper claws.

The problem is that NATO, like governments everywhere, are pretty terrible at the internet. Memes arent really part of NATOs arsenal yet, even if the alliance is desperately trying to tap into ideas from the private sector about how best to use social media.

Kremlin-backed trolls and internet-savvy ISIS supporters run circles around government social media programs, often run by stodgy diplomats with no authority to be creative. (The quest for funny memes is particularly tortured: In March, NATOs Stratcom COE published Stratcom Laughs: In Search of an Analytical Framework, which included a chapter on Humor as a Communication Tool: Designing Framework for Analysis.)

And government attempts at weaponizing humor can lead to some awkward moments.

Such as the time NATO instructed its public diplomacy staff to create a viral video (nothing says military bureaucracy like ordering internet virality to be magically conjured up.)

After half a million Euros, heres the result:

What looks to be a horror film shot on an iPhone turns out to be a nice family reunion because of NATO, of course. (The other two videos in this weird PR series are equally strange and, based on the page views, conspicuously un-viral. The project was quietly dropped after it was rolled out.)

Or then theres the State Departments own Think Again, Turn Away program to win the hearts and minds of would-be jihadists with snarky retorts to the America-bashing, pro-ISIS brigades on Twitter. Alas, it turns out an official State Department social media account arguing with jihadist supporters about the Abu Ghraib prison abuse scandal over Twitter doesnt actually amount to a plan for defeating ISIS.

But if these awkward attempts fail, at least theyre trying. And who knows, now that Trump has discovered what NATO does, maybe he can lend the alliance some of his own social media magic.

The Guardian view on immortality: not for the faint-hearted – The Guardian

Posted: at 11:47 pm

Good Friday seems a suitable day to consider the fact that, in an era in which life expectancy everywhere has almost doubled, humankind is more confused than ever aboutdeath. Nearly half of the British population supposes that death is complete annihilation; an almost equal number still believes in some form of life after death, and, for a subject notably lacking in eyewitness data, a surprisingly small proportion, less than 10%, acknowledge they do not know what happens. Meanwhile, in California but also elsewhere, there are enormously rich men who believe that death is a problem witha technological solution which they hope to live to profit from.

Ideals of technological immortality come in two sorts. There are those who hope that their bodies will be preserved or at least prolonged almost indefinitely, usually by freezing. There is absolutely no reason to suppose that the present technology allows brains to be frozen and rethawed without being reduced to a unworkable state. To hope that this will be changed by some future breakthroughs is an act of faith at least as remarkable as supposing that Jesus rose from the dead. That belief was at least marked since its earliest appearance by a saving ambiguity about what it might actually mean. Saint Paul, for example, was absolutely certain it had happened but nowhere managed to explain what it materially might have been.

The second kind of technological immortality presumes an immaterial soul a pattern of electrical and chemical activity that can be copied from brains into silicon and then reactivated, either inside a computer or transferred back into a conveniently available human brain. Possibly both: one contemporary science fiction novel, Cory Doctorows Walkaway, takes the idea of personalities as computer programs to its logical consequence, and envisages multiple copies of the same program the same person running simultaneously on different networks. This is the closest anyone will ever get to the fantasy of cloning identical human beings.

These approaches to the afterlife differ from most of the world religions in that they have no moral aspect. Perhaps to the believers it is a moral quality to be rich enough to afford such fantasies, but to the rest of the world it looks like a giant leap backwards. This amoral approach to immortality reaches back to a world before the great proselytising world religions. Christianity, Islam and Buddhism all have conceptions of an afterlife which will make up for injustice before death. This was an important novelty. Most other religious systems, if they had any concept of an afterlife, had one without justice. The twittering shades whom Odysseus fed with blood were not being punished for anything except being dead. The nearest that a ghost can come to justice is a craving for revenge. Although belief in heaven and hell can gratify that craving, so that a Christian journalist, outraged by the slaughter of Christians in Egypt this week, consoles himself that the murderers will suffer a thousand times worse in hell, it has also served to underpin a concept of justice wider than revenge and capable of bringing an end to reprisals.

A belief in heaven and hell tends to enforce social norms, discouraging cheating on the one hand, but also holding the potential to make this life pretty hellish for those who fall outside the norms for any reason, including gay people. Social liberalism often goes hand in hand with a rejection of the afterlife, but so does destructive libertarianism. If this life is all we have, success before death is the only kind worth having. But who is to judge that success if not posterity? This itself implies a kind of afterlife. To evoke posterity is to weep on your own grave, as Robert Graves pointed out, and if you are truly dead you cannot leave your grave to weep on it.

Suppose, though, that the tech billionaires get their wish. Would they be happy then? Theyd certainly be envied. Immortality is after all a promise that people are prepared to die for, whether in expectation of heaven, or of some earthly miracle that will revive their frozen corpses. The possessors would certainly be prepared to kill to retain it. But once attained, at whatever cost to the rest ofus, would it satisfy?

The prospect of a life infinitely prolonged becomes after some time the prospect of infinite futility. Its often said that heaven would be extremely boring because all the interesting people end up in hell. But even the company of saints would be preferable tothat of the disciples of Ayn Rand.

The rest is here:

The Shining and the Immortality of Evil | Den of Geek – Den of Geek US

Posted: at 11:47 pm

This article comes from Den of Geek UK.

Few horror films have been as closely studied and intimately dissected as Stanley Kubrick's The Shining. The simple story of a family ripped apart by the effects of a remote, haunted hotel, Kubrick's film has only grown in mystique since its release in 1980. Clearly, there's far more going on below the surface, but what does Kubrick's imagery and symbolism - much of it unique to the film, and absent from Stephen King's source novel - actually mean?

Rodney Ascher's superb 2012 documentary Room 237 pulled together some of the more outlandish theories about The Shining. It's Kubrick's veiled confession that he helped NASA fake the 1969 Moon landings, goes one line of thinking. No, it's an allusion to the horrors of World War II and the holocaust, says a different theorist. Wrong again, another voice suggests: it's a retelling of the Minotaur myth. Often, these theories are based on incidental background details - a home-knit Apollo 11 jumper, the specific make of a typewriter, a tin of baking powder, a poster that looks a bit like a mythical beast if you squint hard enough.

There's a richness and attention to detail and ambiguity in Stanley Kubrick's movies that invites this kind of close study, though few films in his career have sparked quite so many varied readings as The Shining. To an already crowded list, we offer an additional theory: The Shining's about the immortality of evil.

Kubrick embarked on The Shining in the wake of 1975's Barry Lyndon, his glacial period film which, despite its reputation today, was a critical and financial failure at the time. The director therefore threw himself into a more commercial project: an adaptation of The Shining. Stephen King's novels had made him phenomenally popular in the late 1970s, and King was among a generation of storytellers who took horror out of the castles and capes of Dracula and Frankenstein and into the modern era.

King's novels Carrie (1974) and 'Salem's Lot (1975) took paranormal powers and vampirism into the 20th century, just as such hit films as Rosemary's Baby (based on the novel by Ira Levin) and The Exorcist (adapted by William Peter Blatty from his own book) had introduced a classier, more contemporary brand of horror in cinemas.

When Kubrick took on The Shining, he was therefore following a fashionable trend among respected filmmakers. Roman Polanski, William Friedkin, and Nicolas Roeg had all crafted deeply individual horror films in the 60s and 70s. The decade also introduced such wayward talents as Wes Craven (Last House on the Left, The Hills Have Eyes), Tobe Hooper (The Texas Chain Saw Massacre), and David Cronenberg (Shivers, Rabid).

When Kubrick started work on The Shining, he showed off the work of another upcoming filmmaker he greatly admired: Eraserhead, the surreal, immensely disturbing debut by David Lynch. The Shining would, of course, wind up being wildly different from Eraserhead's monochrome hellscape, yet Kubrick evidently appreciated how Lynch used sound and imagery to create an oppressive atmosphere of dread.

To Stephen King's later chagrin, Kubrick wasn't particularly interested in adapting The Shining beat for beat. For one thing, the filmmaker didn't have much time for stories of ghosts and the afterlife - something Kubrick told King in no uncertain terms one day in the late 70s.

As King recalled in one hilarious anecdote, Kubrick called King up at 7:00 am one morning - completely out of the blue - and said, "Hi. Stanley Kubrick here. I actually think stories of the supernatural are optimistic, don't you?"

King, hung over, covered in shaving cream, two kids screaming in the background, gripped the telephone and murmured, "I don't exactly know what you mean by that."

"Well," Kubrick replied, "supernatural stories all posit the basic suggestion that we survive death. If we survive death, that's optimistic, isn't it?"

King asked, "Well, what about hell?"

There was a long, ominous pause, like the silence after a thunderclap.

"I don't believe in hell," Kubrick said, and hung up.

Kubrick therefore set about reworking his own vision of The Shining with screenwriter Diane Johnson, using only the basic framework of King's story. A husband, Jack Torrance (Jack Nicholson), wife Wendy (Shelley Duvall), and their young son Danny (Danny Lloyd), who has telepathic powers, spend the winter at the Overlook, a hotel located in the mountains of Colorado. The husband, Jack intends to use the weeks of seclusion to write a novel. The malevolent spirits in the hotel, on the other hand, have other ideas. As strange apparitions manifest themselves to both son and father, Jack's already threadbare sanity begins to unravel...

The shoot of Kubrick's The Shining was legendarily difficult, as the filmmaker's exacting methods took their toll. Nicholson and Duvall were required to provide take after take - a pivotal stairway confrontation between the pair was shot anywhere from 45 to 125 times depending on whose account you believe. Scatman Crothers, who plays the hotel chef Dick Hallorann, spent so long reciting his lines in front of the camera that he eventually lost his temper with Kubrick.

By the time filming had concluded in 1979, Kubrick had spent about a year at Elstree Studios, obsessing over individual scenes and tiny details. As cast and crew began to crack under the pressure of all the script rewrites and long work days, it must have felt at times as though the production itself was descending into madness.

If critics struggled with The Shining when it finally emerged in 1980, then maybe that's because it didn't adhere to the conventions of a typical horror movie. The Overlook's supernatural threat - if it exists at all in the movie - is kept ambiguous. Its pace is slow and deliberate; and unlike the Jack Torrance in King's book, who's initially presented as a flawed yet likeable character before the ghosts get to him, Jack Nicholson's protagonist is fairly cold and sinister before he even sets foot in the Overlook.

This latter point is surely deliberate, however. Kubrick's implication is that, far from being corrupted by the evil presence in the Overlook, Jack Torrance is simply given license by it. The evil's already present in Jack - it merely takes a few nudges from the Overlook's remote location and ghostly echoes to bring it out into the open.

The Shining's opening credit sequence could be read as the first hint at this. As Wendy Carlos' doom-laden electronic music plays in the background, a helicopter shot follows the Torrance family's journey through the Colorado countryside in their car. The camera becomes a detached, floating spirit, hovering over or just behind the central characters - much as it does through the rest of the film in those celebrated Steadicam shots Kubrick so insistently employs. Evil is following.

In King's novel, there's the suggestion that the Overlook has somehow sucked up the evil things that have taken place within its walls. Kubrick goes a step further, with a character's line that the hotel was built on an old Indian burial ground implying that the presence may be older than the structure itself. And if we follow the theory that The Shining isn't about ghosts, but about evil, then this certainly makes sense. Evil doesn't inhabit buildings, it inhabits human beings - even ordinary, unremarkable ones, like Jack Torrance.

There's plenty of support from Kubrick to support this reading of the film; in Paul Duncan's Stanley Kubrick: The Complete Films, the filmmaker said:

"There's something inherently wrong with the human personality. There's an evil side to it. One of the things that horror stories can do is to show us the archetypes of the unconscious; we can see the dark side without having to confront it directly."

Stephen King was certainly confronting his own demons when he wrote his novel. The inspiration from The Shining came to him during a stay at The Stanley Hotel in Colorado, where King fused a stay in the real room 217 - supposedly haunted - with the difficulties he was having as a father of two young children.

"Sometimes you confess," King said in The Stephen King Companion, published in 1989. "You always hide what you're confessing to. That's one of the reasons why you make up the story. When I wrote The Shining, for instance, the protagonist [...] is a man who's broken his son's arm, who has a history of child beating, who is beaten himself. And as a young father with two children, I was horrified by my occasional feelings of real antagonism toward my children..."

The Shining therefore de-emphasizes the moving topiary animals and ghosts of the novel and focuses the story more squarely on Jack Torrance's growing capacity for violence. The Overlook becomes a place where, away from the gaze of society, moral laws are suspended, and Jack is given license to do all the things he's long fantasized about.

As Jack drunkenly confesses to Joe Turkel's impassive barman, Lloyd, he'd already subjected his young son to violent abuse before he even set foot in the Overlook:

"For as long as I live, she'll never let me forget what happened. I did hurt him once, okay? But it was an accident. Completely unintentional [...] a momentary loss of muscular coordination."

The Shining then ties the evil of domestic violence to evil in a more general sense. Evil doesn't just reside in Jack; it's everywhere. As the sinister Delbert Grady (Philip Stone) tells Jack, "You've always been the caretaker. I've always been here."

The references to the genocide of Native Americans, as picked up by other theorists, could tie into The Shining's theme of evil presenting itself in different ways. The elevator doors opening, the blood gushing up, seemingly from the foundations of the Overlook itself, could be a symbol of the hotel's grim past - and the country as a whole.

In the same scene with Jack quoted above, Delbert Grady uses a racial slur to describe Dick Halloran that strikes out of the film like an ice pick - an example of another kind of evil that sticks to our species like a leech. Perhaps this is what Jack means by the odd, apparently throwaway line: "White man's burden." If we don't feel guilty about the skeletons in our species' closet, then maybe we should.

Away from The Shining, Kubrick's films frequently explored the darker continents of human nature - particularly the destruction wrought by flawed men. His adaptation of Nabokov's Lolita was about the horrors wrought by a sexual predator. At its heart, Dr. Strangelove was about how a world led by neurotic, sexually repressed men might be obliterated by nuclear weapons. A Clockwork Orange and Full Metal Jacket both dealt explicitly with violence and dehumanization.

The Shining could therefore be seen as a continuation of those themes: a continuation of the things "inherently wrong with the human personality," but in a horror context. It's not the ghosts in haunted houses we should be afraid of, Kubrick seems to suggest, but the demons that lurk within ourselves.

Time and again, the director returns to the symbol of the maze: the hedge maze in the Overlook garden, the incomprehensible network of corridors in the building itself. This is The Shining's lasting, chilling implication: the blacker sides of human nature are hardwired into our DNA. Inextricable. Inescapable.

Kathy Salazar (17) created an Alternative Medicine club with the help of Doctor David Gehling from Decorah Chiropractic in hopes of providing students with information on alternative medicine.

The club had its first meeting the week of April 12 and meetings will continue into the next year. Alternative medicine is defined as therapies and treatments that are implemented as substitutes for other mainstream medical therapies and treatments. Students involved in the alternative medicine club will study these therapies and treatments scientifically and academically.

The alternative medicine club is lead by both Salazar and Gehling. Gehling will teach students about different kinds of alternative medicine. As a certified chiropractor he brings a professional view on alternative medicine.

The club began because Ive had great experiences with alternative medicine, Salazar said. I wanted other people to know that its another option along with traditional methods of medicine.

The alternative medicine club will meet approximately twice a month. The first meeting is going to be lecture-based with guest speakers and seminars from Gehling. The second meeting of the month will be a hands-on learning experience with alternative medicine.

Meetings will consist of Gehling coming and speaking, maybe bringing some of his equipment too, Salazar said. He also suggested heading into the labs to work with some anatomical structures. He wants people who are going into medicine to understand that when patients come to them with questions about alternative medicine that they can say that Yes, this is real and it works.

A January term class for first-year students allows students to explore the world of alternative medicine. Students, such as Alexis Olson (20), learned how to reverse a humans natural energy, how to use herbs to help remedy illnesses, and different points on the body that can be massaged to counter chronic pains.

It was fun to explore different therapies that Id never heard of before, Olson said. I had so much fun in this class, and I actually use the remedies that we were provided in class.

One of the techniques Olson learned in class is reversing someones energy.

The purpose of reversing energy is to stay focused, Olson said. It also helps maintain someones positive energy flow and recharge yourself.

Similar to the class, the club will give people an introduction to alternative medicine and how it can be used in everyday life. Those who attend club meetings will research and experiment with the scientific aspects of alternative medicine.

Basically this club would be a resource for students, Salazar said. You dont get this kind of exposure in Decorah, IA. Its made my life better, honestly.

In other parts of the world, these alternative medicine practices are commonly used in everyday life. Current members were drawn to the club for many reasons.

When I was growing up I had a lot of exposure to different kinds of alternative medicine, Haley Ogoy (17) said. I always thought it was fascinating having grown up in Juneau, AK, and I wanted to help people have a better understanding of alternative medicine.

Another focus of the group is to help medical students to expand their knowledge of different treatments, therapies, and remedies outside of the traditional methods. These include home remedies that are easily accessible to all people.

I think, especially for pre-med students, Luther prides itself on having a very well-rounded community, Ogoy said. This is just another way for people to discover new methods for treatments.

Salzar hopes the club will help make Luther a more diversely educated community.

Not only will this club be super helpful, especially to college students but it can help people find other career options through the club, Salazar said.

Items such as acupuncture, chiropractic practices, cleansing diets, holistic healing, spiritual healing, herbs and oils, and meditation can all fall under the category of alternative medicine.

Students would be using these skills on a day-to-day basis, Salazar said. It helps with stress and daily pains, its super useful.

10 Foods (and Vitamins and Supplements!) to Boost Your ADHD Brain – ADDitude

Posted: at 11:46 pm

Medication helps many adults and children with ADHD, but it doesnt work for everyone.

Parents and adults see me either because the medication isnt doing the job, or they want more improvement and cant increase the dosage without increasing side effects, says Richard Brown, M.D., associate clinical professor of psychiatry at Columbia University College of Physicians and Surgeons, and coauthor of the recent book How to Use Herbs, Nutrients, and Yoga in Mental Health Care.

Medication does not cure ADHD, and it should never be the only treatment, says Edward Hallowell, M.D., coauthor of the best-selling Driven to Distraction: Recognizing and Coping with Attention Deficit Disorder from Childhood Through Adulthood. Diet and nutrition play key roles in how well the ADHD brain operates. Toward that end, here are 10 foods, ADHD supplements, and herbs that you should add to your treatment plan. As always, talk with your doctor first before doing so.

Poor nutrition can cause a child or adult with ADHD to become distracted, impulsive, and restless. The right foods, on the other hand, can lessen those symptoms.

Protein Foods rich in protein lean beef, pork, poultry, fish, eggs, beans, nuts, soy, and dairy products are used by the body to make neurotransmitters, the chemicals released by brain cells to communicate with each other. Protein can prevent surges in blood sugar, which increase hyperactivity.

Because the body makes brain-awakening neurotransmitters when you eat protein, start your day with a breakfast that includes it, says Laura Stevens, M.S., a nutritionist at Purdue University and author of 12 Effective Ways to Help Your ADD/ADHD Child: Drug-Free Alternatives for Attention-Deficit Disorders. Dont stop there. Look for ways to slip in lean protein during the day, as well.

Balanced Meals Hallowell suggests that you divide your lunch and dinner plate in the following way: Half of the plate should be filled with fruits and vegetables, one fourth with a protein, and the remaining fourth with a carbohydrate, preferably one rich in fiber whole wheat pasta, whole grain bread, brown rice.

This combination of foods will minimize swings in behavior caused by hunger or by a shortfall of a particular nutrient. Fiber prevents blood-sugar levels from spiking and plummeting, which can increase inattention.

Many diets are deficient in key vitamins and minerals that may improve attention and alertness, says Brown. Supplements can often fill in the dietary gaps.

Multivitamin/Multimineral If your child is a picky eater or eats lots of take-out food, he wont get the daily recommended value of vitamins and minerals. A daily multivitamin/multimineral will ensure that he does, no matter how finicky he is.

B Vitamins Studies suggest that giving children who have low levels of B vitamins a supplement improved IQ scores (by 16 points) and reduced aggression and antisocial behavior. Vitamin B-6 seems to increase the brains levels of dopamine, which improves alertness, says Brown.

Zinc, Iron, and Magnesium Zinc synthesizes dopamine and augments the effects of methylphenidate. Low levels of this mineral correlate with inattention.

Iron is also necessary for making dopamine. In one small study, ferritin levels (a measure of iron stores) were low in 84 percent of ADHD children compared to 18 percent of the control group. Low iron levels correlate with cognitive deficits and severe ADHD.

Adequate levels of magnesium have a calming effect on the brain, says Brown. While diet is the safest way to increase mineral levels, a multivitamin/multimineral with iron will ensure that you or your child will get the daily reference value (DRV) of all three.

Omega-3s One study suggested that a subgroup of boys with ADHD are deficient in omega-3 fatty acids compared with those who have no symptoms of the condition.

Another study showed that omega-3s-found in cold-water, fatty fish, such as sardines, tuna, and salmon-tend to break down more readily in the bodies of patients with ADHD than in those without the condition. Individuals with ADHD who have low blood levels of omega-3s will show the biggest improvement in mental focus and cognitive function, says Brown.

Picamilon A combination of the B-vitamin niacin and gamma-aminobutyric acid, picamilon improves blood flow to the brain and has mild stimulative effects, improving alertness and attention. It can also reduce aggressive behavior. Both adults and children derive benefits from this supplement, says Brown.

Most children and adults derive moderate benefits from the vitamin-mineral approach, says Brown. Those with more significant ADHD may need stronger stuff-namely, herbs.

Ginkgo and Ginseng These herbs are cognitive activators, says Brown. They act like stimulants without the side effects. Typically, adults and children who take ginkgo and ginseng improve on ADHD rating scales, and are less impulsive and distractible. Asian ginseng may overstimulate younger children. If this happens to your child, switch to American ginseng.

Pycnogenol An extract made from French maritime pine bark, pycnogenol was found to improve hyperactivity and sharpen attention, concentration, and visual-motor coordination in students after one month, based on standardized measures and teacher and parent ratings.

The herb pycnogenol is also rich in polyphenols, antioxidants that protect brain cells from free radicals. The first double-blind study on the herb was published in 2006, confirming its benefits, says Brown. Larger randomized trials, though, are needed.

Rhodiola Rosea Made from a plant of the same name that grows in the Arctic, this herb can improve alertness, attention, and accuracy. It can be too stimulating for young children, and is occasionally beneficial in children ages eight to 12. It is most useful, says Brown, for students in junior high, high school, and college, who have to complete long papers and spend hours reading.

Nourish your bones: get vital nutrients through diet, supplements – Chicago Sun-Times

Posted: at 11:46 pm

Unlike the static human skeletons that commonly hang in biology classrooms, your bones are continually being broken down and rebuilt. In fact, your entire skeleton is replaced about every 10 years. In addition to exercise, about 20 different nutrients help prevent the weakening of bones that leads to osteoporosis. We review nutrients youre more than likely falling short on and where to get them.

Calcium Requirement for adults: 1,000-1,300 mg (milligrams)

Calcium has the strongest research evidence of any nutrient for its role in supporting healthy bones, according to a 2016 position paper from the National Osteoporosis Foundation.

Sources: Dairy foods, fortified foods (such as orange juice, tofu and soy milk), fish with edible bones (sardines, canned salmon), bok choy and kale.

Vitamin D

Vitamin D helps you absorb calcium from food and supplements. Without vitamin D, less than 10 percent of the calcium you consume is absorbed.

Requirement for adults: 600-800 International Units. However, a 2014 analysis by Canadian experts and a March 2015 analysis by U.S. experts, both published in Nutrients, report that the Institute of Medicine made a significant statistical error in calculating vitamin D needs, making current recommendations too low. Ask your doctor to test your vitamin D blood level; it should be at least 32 ng/mL to support bone health.

Sources: Fortified dairy foods, egg yolks, salmon and tuna. To assess how much vitamin D youre getting from sun exposure daily, use the dminder smartphone app (dminder.ontometrics.com), which vitamin D expert Michael F. Holick, Ph.D., M.D. helped develop.

Magnesium Requirement for adults: 310-420 mg

Magnesium is a component of bone, giving it resiliency and protection against fractures; it also is essential for converting vitamin D to its active form in the body. If you take a calcium and vitamin D supplement, take magnesium, too, because high calcium intake causes magnesium loss, and most Americans dont consume enough magnesium.

Sources: Nuts, seeds, leafy green vegetables, whole grains and legumes.

Vitamin K Requirement for adults: 75-120 mcg (micrograms)

Vitamin K is found in two main forms in food, K1 and K2, and your body may convert limited amounts of vitamin K1 to K2. Both forms play a role in blood clotting (and work against the anti-clot drug warfarin), but vitamin K2 also helps prevent calcium from depositing in arteries (the process of atherosclerosis) and instead directs calcium to bones and helps bind the mineral to your skeleton.

Sources: K1 is found in dark, leafy green vegetables such as kale and spinach; K2 is in natto (fermented soybeans), cheese, grass-fed meat and liver.

Vitamin B12 & Folate Requirement for adults: For folate, 400-600 mcg. For B12, 2.4 -2.8 mcg. (Your doctor may advise higher amounts if you have elevated homocysteine.)

Vitamin B12 and folate support bone health by helping to keep levels of homocysteine, a compound that stimulates the breakdown of bone, low. This role is further confirmed by genetic studies that reveal a link between an increased risk of osteoporosis in older adults and a common gene mutation (MTHFR C677T) that can lead to high homocysteine levels.

Sources: B12 is in meat, fish and other animal foods, as well as in fortified foods, including cereals and nutritional yeast. Folate is in leafy green vegetables, broccoli, asparagus and legumes.

Vitamin intake poses potential health benefits, risks by Tina Chai | Apr 13 2017 | 22 hours ago

According to a 2013 Gallup poll, half of all Americans report regular vitamin or mineral supplement intake, with annual U.S. vitamin sales totaling $12 billion. Despite the widespread consumption of vitamins, it is unclear whether they offer the health benefits pharmaceutical companies claim.

Vitamins and minerals range in form and type, from folic acid and iron pills to common multivitamin chewables. These pills, tablets and liquids are biochemically diverse and vary in their molecular compound formulas.

A Multivitamin is the most commonly used supplement, and generally contains both vitamins such as Vitamin C, Vitamin K, etc. and minerals such as iron, chromium, magnesium, etc., Elson Student Health Center nutritionist Melanie Brede said in an email to The Cavalier Daily. Each vitamin or mineral is a unique compound. An ingredient list on a multivitamin supplement label will list the common and chemical name of each compound.

People often take vitamins to remedy diagnosed or perceived nutritional deficiencies. Depending on factors such as age, sex, pregnancy or health impairment, vitamin and mineral intake levels usually measured by the Recommended Daily Allowance are adjusted appropriately for each specific condition. However, Brede said taking vitamins is only effective in addressing actual dietary or health insufficiencies, and offer no advantage when such are absent.

Lawrence Appel, director of the Welch Center for Prevention, Epidemiology and Clinical Research at Johns Hopkins University, also assessed the fallacy that vitamins ensure health and energy.

There are many possible reasons [for vitamin intake], most related to some belief that consumption of vitamins will improve health, Appel said in an email to The Cavalier Daily. First, there is a [mystique] to the word vitamin. If they were called chemicals which they are many people would not take them. Second, marketing is extensive. Third, there are medical studies, most non-definitive, which suggest or imply the potential of benefit. Fourth, companies have gotten special regulatory status which allows them to market more easily (and with less evidence) than drugs.

While there is currently little data in scientific literature proving the link between vitamin consumption and health benefits, research on vitamins remains prevalent.

Research is ongoing to update recommended levels of various nutrients, Brede said. For example, historically, Vitamin D was considered essential for preventing deficiency diseases impacting skeletal health. More recent research has expanded our understanding of the roles Vitamin D plays in health, and the recommended levels were revised in the last decade.

Just as there are possible benefits of vitamin intake, there are potential risks related to overdosing or absorbing unnecessary minerals in the body.

Vitamin E supplements are associated with increased mortality at high doses [and] beta-carotene supplements increased the risk of lung cancer among smokers, Appel said.

Due to the uncertain or potentially harmful effects of certain vitamins and minerals, Brede suggested eating healthy food as the best alternative to vitamins.

A balanced diet is a safe and effective way to ensure adequate, but not too much, of the nutrients we need, Brede said. Getting a variety of colorful fruits and vegetables, whole grains, lean meats, fish, dairy, nuts and vegetable oils provides the vitamins and minerals we need. Supplemental vitamins and minerals can be used effectively to fill gaps if food allergies or intolerances prevent adequate intake of food sources of specific nutrients.

Likewise, Appel proposed that a healthy diet and lifestyle should be favored over vitamin consumption.

Quite frankly, it is amazing to me that so many people take vitamin and mineral supplements, often at very high doses, when the evidence is so weak, Appel said. Some simple advice for all of us Eat less, eat right, move more.
