YOU REMEMBER CLAW machines, those confounded scams that bilked you out of your allowance. They were probably the closest thing you knew to an actual robot, really. They’re not, of course, but they do have something very important in common with legit robots: They’re terrible at handling objects with any measure of dexterity.

You probably take for granted how easy it is to, say, pick up a piece of paper off a table. Now imagine a robot pulling that off. The problem is that a lot of robots are taught to do individual tasks really well, with hyper-specialized algorithms. Obviously, you can’t get a robot to handle everything it’ll ever encounter by teaching it how to hold objects one by one.

Nope, that’s an AI’s job. Researchers at the University of California Berkeley have loaded a robot with an artificial intelligence so it can figure out how to robustly grip objects it’s never seen before, no hand-holding required. And that’s a big deal if roboticists want to develop truly intelligent, dexterous robots that can master their environments.

The secret ingredient is a library of point clouds representing objects, data that the researchers fed into a neural network. “The way it’s trained is on all those samples of point clouds, and then grasps,” says roboticist Ken Goldberg, who developed the system along with postdoc Jeff Mahler. “So now when we show it a new point cloud, it says, ‘This here is the grasp, and it’s robust.’” Robust being the operative word. The team wasn’t just looking for ways to grab objects, but the best ways.

Using this neural network and a Microsoft Kinect 3-D sensor, the robot can eyeball a new object and determine what would be a robust grasp. When it’s confident it’s worked that out, it can execute a good grip 99 times out of 100.

“It doesn’t actually even know anything about that the object is,” Goldberg says. “It just says it’s a bunch of points in space, here’s where I would grasp that bunch of points. So it doesn’t matter if it’s a crumpled up ball of tissue or almost anything.”

Imagine a day when robots infiltrate our homes to help with chores, not just vacuuming like Roombas but doing dishes and picking up clutter so the elderly don’t fall and find themselves unable to get up. The machines are going to come across a whole lot of novel objects, and you, dear human, can’t be bothered to teach them how to grasp the things. By teaching themselves, they can better adapt to their surroundings. And precision is pivotal here: If a robot is doing dishes but can only execute robust grasps 50 times out of 100, you’ll end up with one embarrassed robot and 50 busted dishes.

Here’s where the future gets really interesting. Robots won’t be working and learning in isolation—they’ll be hooked up to the cloud so they can share information. So say one robot learns a better way to fold a shirt. It can then distribute that knowledge to other robots like it and even entirely different kinds of robots. In this way, connected machines will operate not only as a global workforce, but as a global mind.

At the moment, though, robots are still getting used to our world. And while Goldberg’s new system is big news, it ain’t perfect. Remember that the robot is 99 percent precise when it’s already confident it can manage a good grip. Sometimes it goes for the grasp even when it isn’t confident, or it just gives up. “So one of the things we’re doing now is modifying the system,” Goldberg says, “and when it’s not confident rather than just giving up it’s going to push the object or poke it, move it some way, look again, and then grasp.”

Fascinating stuff. Now if only someone could do something about those confounded claw machines.

It’s big news, set to shock, amaze, and entertain the world.

But unfortunately, it’s got nothing to do with extraterrestrial stoners melding with Earth’s plants.

However, since you’re now reading, you’ll almost certainly be interested in this research that looked into the clicking and sharing behaviors of social media users reading content (or not) and then sharing it on social media.

We noticed long ago that many of our followers will happily like, share and offer an opinion on an article – all without ever reading it. We’re not the only ones to notice this. Last April, NPR shared an article on their Facebook page which asked “Why doesn’t America read anymore?”. The joke, of course, is that there was no article. They waited to see if their followers would weigh in with an opinion without clicking the link, and they weren’t disappointed.

We’ve been hoping for a chance to try it ourselves, and this seemed like the perfect opportunity. Yackler had some fun with the same article and managed to fool a bunch of people.

A group of computer scientists at Columbia University and the French National Institute looked into a dataset of over 2.8 million online news articles that were shared via Twitter. The study found that up to 59 percent of links shared on Twitter have never actually been clicked by that person’s followers, suggesting that social media users are more into sharing content than actually clicking on and reading it.

“People are more willing to share an article than read it,” the study’s co-author Arnaud Legout said in a statement, Washington Post reports. “This is typical of modern information consumption. People form an opinion based on a summary, or a summary of summaries, without making the effort to go deeper.”

This study looks into the psychology behind what makes people want to share content. Research conducted by The New York Times Customer Insight Grouplooked into what motivates people to share information. Just under half of the people asked in the survey said they share information on social media to inform people and to “enrich” those around them. Conversely, they found 68 percent share to reinforce and project a certain image of themselves – in a sense, to “define” themselves.

World Renowned Heart Surgeon Speaks Out On What Really Causes Heart Disease

We physicians with all our training, knowledge and authority often acquire a rather large ego that tends to make it difficult to admit we are wrong. So, here it is. I freely admit to being wrong. As a heart surgeon with 25 years experience, having performed over 5,000 open-heart surgeries, today is my day to right the wrong with medical and scientific fact.

I trained for many years with other prominent physicians labelled “opinion makers.”  Bombarded with scientific literature, continually attending education seminars, we opinion makers insisted heart disease resulted from the simple fact of elevated blood cholesterol.

The only accepted therapy was prescribing medications to lower cholesterol and a diet that severely restricted fat intake. The latter of course we insisted would lower cholesterol and heart disease. Deviations from these recommendations were considered heresy and could quite possibly result in malpractice.

It Is Not Working!

These recommendations are no longer scientifically or morally defensible. The discovery a few years ago that inflammation in the artery wall is the real cause of heart disease is slowly leading to a paradigm shift in how heart disease and other chronic ailments will be treated.

The long-established dietary recommendations have created epidemics of obesity and diabetes, the consequences of which dwarf any historical plague in terms of mortality, human suffering and dire economic consequences.

Despite the fact that 25% of the population takes expensive statin medications and despite the fact we have reduced the fat content of our diets, more Americans will die this year of heart disease than ever before.

Statistics from the American Heart Association show that 75 million Americans currently suffer from heart disease, 20 million have diabetes and 57 million have pre-diabetes. These disorders are affecting younger and younger people in greater numbers every year.

Simply stated, without inflammation being present in the body, there is no way that cholesterol would accumulate in the wall of the blood vessel and cause heart disease and strokes. Without inflammation, cholesterol would move freely throughout the body as nature intended. It is inflammation that causes cholesterol to become trapped.

Inflammation is not complicated — it is quite simply your body’s natural defence to a foreign invader such as a bacteria, toxin or virus. The cycle of inflammation is perfect in how it protects your body from these bacterial and viral invaders. However, if we chronically expose the body to injury by toxins or foods the human body was never designed to process,a condition occurs called chronic inflammation. Chronic inflammation is just as harmful as acute inflammation is beneficial.

What thoughtful person would willfully expose himself repeatedly to foods or other substances that are known to cause injury to the body? Well,smokers perhaps, but at least they made that choice willfully.

The rest of us have simply followed the recommended mainstream diet that is low in fat and high in polyunsaturated fats and carbohydrates, not knowing we were causing repeated injury to our blood vessels. This repeated injury creates chronic inflammation leading to heart diseasestroke, diabetes and obesity.

Let me repeat that: The injury and inflammation in our blood vessels is caused by the low fat diet recommended for years by mainstream medicine.

What are the biggest culprits of chronic inflammation? Quite simply, they are the overload of simple, highly processed carbohydrates (sugar, flour and all the products made from them) and the excess consumption of omega-6 vegetable oils like soybean, corn and sunflower that are found in many processed foods.

Take a moment to visualize rubbing a stiff brush repeatedly over soft skin until it becomes quite red and nearly bleeding. you kept this up several times a day, every day for five years. If you could tolerate this painful brushing, you would have a bleeding, swollen infected area that became worse with each repeated injury. This is a good way to visualize the inflammatory process that could be going on in your body right now.

Regardless of where the inflammatory process occurs, externally or internally, it is the same. I have peered inside thousands upon thousands of arteries. A diseased artery looks as if someone took a brush and scrubbed repeatedly against its wall. Several times a day, every day, the foods we eat create small injuries compounding into more injuries, causing the body to respond continuously and appropriately with inflammation.

While we savor the tantalizing taste of a sweet roll, our bodies respond alarmingly as if a foreign invader arrived declaring war. Foods loaded with sugars and simple carbohydrates, or processed with omega-6 oils for long shelf life have been the mainstay of the American diet for six decades. These foods have been slowly poisoning everyone.

How does eating a simple sweet roll create a cascade of inflammation to make you sick?

Imagine spilling syrup on your keyboard and you have a visual of what occurs inside the cell. When we consume simple carbohydrates such as sugar, blood sugar rises rapidly. In response, your pancreas secretes insulin whose primary purpose is to drive sugar into each cell where it is stored for energy. If the cell is full and does not need glucose, it is rejected to avoid extra sugar gumming up the works.

When your full cells reject the extra glucose, blood sugar rises producing more insulin and the glucose converts to stored fat.

What does all this have to do with inflammation? Blood sugar is controlled in a very narrow range. Extra sugar molecules attach to a variety of proteins that in turn injure the blood vessel wall. This repeated injury to the blood vessel wall sets off inflammation. When you spike your blood sugar level several times a day, every day, it is exactly like taking sandpaper to the inside of your delicate blood vessels.

While you may not be able to see it, rest assured it is there. I saw it in over 5,000 surgical patients spanning 25 years who all shared one common denominator — inflammation in their arteries.

Let’s get back to the sweet roll. That innocent looking goody not only contains sugars, it is baked in one of many omega-6 oils such as soybean. Chips and fries are soaked in soybean oil; processed foods are manufactured with omega-6 oils for longer shelf life. While omega-6’s are essential -they are part of every cell membrane controlling what goes in and out of the cell — they must be in the correct balance with omega-3’s.

If the balance shifts by consuming excessive omega-6, the cell membrane produces chemicals called cytokines that directly cause inflammation.

Today’s mainstream American diet has produced an extreme imbalance of these two fats. The ratio of imbalance ranges from 15:1 to as high as 30:1 in favor of omega-6. That’s a tremendous amount of cytokines causing inflammation. In today’s food environment, a 3:1 ratio would be optimal and healthy.

To make matters worse, the excess weight you are carrying from eating these foods creates overloaded fat cells that pour out large quantities of pro-inflammatory chemicals that add to the injury caused by having high blood sugar. The process that began with a sweet roll turns into a vicious cycle over time that creates heart disease, high blood pressure, diabetes and finally, Alzheimer’s disease, as the inflammatory process continues unabated.

There is no escaping the fact that the more we consume prepared and processed foods, the more we trip the inflammation switch little by little each day. The human body cannot process, nor was it designed to consume, foods packed with sugars and soaked in omega-6 oils.

There is but one answer to quieting inflammation, and that is returning to foods closer to their natural state. To build muscle, eat more protein. Choose carbohydrates that are very complex such as colorful fruits and vegetables. Cut down on or eliminate inflammation- causing omega-6 fats like corn and soybean oil and the processed foods that are made from them.

One tablespoon of corn oil contains 7,280 mg of omega-6; soybean contains 6,940 mg. Instead, use olive oil or butter from grass-fed beef.

Animal fats contain less than 20% omega-6 and are much less likely to cause inflammation than the supposedly healthy oils labelled polyunsaturated. Forget the “science” that has been drummed into your head for decades. The science that saturated fat alone causes heart disease is non-existent. The science that saturated fat raises blood cholesterol is also very weak. Since we now know that cholesterol is not the cause of heart disease, the concern about saturated fat is even more absurd today.

The cholesterol theory led to the no-fat, low-fat recommendations that in turn created the very foods now causing an epidemic of inflammation. Mainstream medicine made a terrible mistake when it advised people to avoid saturated fat in favor of foods high in omega-6 fats. We now have an epidemic of arterial inflammation leading to heart disease and other silent killers.

What you can do is choose whole foods your grandmother served and not those your mom turned to as grocery store aisles filled with manufactured foods. By eliminating inflammatory foods and adding essential nutrients from fresh unprocessed food, you will reverse years of damage in your arteries and throughout your body from consuming the typical American diet.


Mountains of Obamacare-related paperwork and the threats of severe fines for the slightest errors are forcing many doctors to retire and others to shut down their practices and work under the protection of hospitals, and all of it spells bad news for patients.

Galen Institute President Grace-Marie Turner says the exodus is alarming, as evidenced by a Physicians Foundation report showing the number of doctors who say they run an independent practice has dropped from 62 percent in 2008 to 35 percent in 2014. The survey of 20,000 physicians also shows only 17 percent in solo practice. Eighty-one percent of doctors are at full capacity or even overextended. Forty-six percent grade Obamacare as a D or an F. Just 25 percent give the law an A or a B.

For those greatly frustrated by the system, Turner said the government is making their lives miserable.

“The doctors cannot navigate this incredible bureaucracy,” she said. “They may see 40 patients during a day, and then they have mountains of paperwork to fill out. If they slip up and say something in carelessness or not understanding the rules and make a mistake, they could be subject to tens of thousands of dollars in fines. They just cannot expose themselves to that kind of jeopardy.”

Turner said there are two groups involved in shrinking the supply of doctors. First, she said experienced doctors are simply retiring rather than jumping through Obamacare’s bureaucratic hoops.

“Some of the more seasoned, experienced, established physicians are just taking down their shingle and saying, ‘We have had it. We cannot deal with this cookbook medicine. We cannot fight the rules and regulations and legal jeopardy we’re in.’”

She said the toll on health-care quality is sobering.

“They’re leaving practice early,” Turner said. “We’re losing decades of experience and medical expertise when doctors would otherwise be at the prime of their practice, leaving because they cannot deal with the bureaucracy or afford it.”

According to the Physicians Foundation study, doctors say they spend 20 percent of their time on non-clinical paperwork. Thirty-nine percent say they are accelerating retirement plans.

The other trend is doctors merging with hospitals and leaving independent practice.

“A number of physicians who are younger and still have bills to pay and families to support are selling their practices to hospitals, which mean that they basically become employees and have to do what the hospitals say,” Turner said.

The Physicians Foundation report finds that 53 percent of physicians describe themselves as hospital or medical group employees, up from 38 percent in 2008.

Turner said their logic makes sense.

“They really are buying the protection of these big hospital chains, which can hire an army of doctors and bureaucrats to try to help them navigate the bureaucracy,” she said. “The bureaucratization of American medicine is well underway and that does not bode well for patients.”

She says it’s bad for patients in two ways, first because of the realities of being a doctor employed by a hospital.

“Now they have to follow these very strict rules and regulations of these big hospital systems in order to treat a patient. If they don’t, they may either not be paid but they also could be penalized,” said Turner, who is also very worried that the notion of playing it safe is stifling innovation and preventing the development of better treatments.

“Both the doctors who stay in practice, and even more the medical students who apply and are accepted, are people who want to work a 40-hour week,” Turner said. “They’re perfectly happy to follow this cookbook medicine standardization and to not rock the boat by trying to do something innovative that might actually teach us something.”

Turner said increased government control of health care in other countries has consistently meant longer waiting times for treatment. She said cancer patients in Canada can wait up to 16 weeks or more for care after receiving a diagnosis, a span she acknowledges can be a “death sentence.”

In addition to losing good doctors, Turner said doctors are often brought in from other countries, and that can prove very challenging for patients as well.

“When you drive out the established physicians who are saying they are not willing to practice under these kinds of conditions, you still have to have physicians,” Turner said. “We do have many foreign medical graduates in this country, and patients complain that they have a physician who they really can’t communicate with.”

But while excoriating the mountain of rules and regulations Washington is piling onto physicians and others in the medical community, Turner said Americans should never doubt how much doctors and nurses want to help people.

“When you look at the nurses and the doctors that are still taking care of patients, it is so inspiring to see how much they continue to want to practice good medicine,” she said. “They are devoted to their patients. But they are so stressed in many cases and so frustrated, saying, ‘I got into this business to take care of patients, not to fill out all this paperwork and bureaucracy.’”
