Man Eats Nothing but McDonald’s for 180 days…and loses weight

shutterstock_220538989There have been plenty of diet fads over the years as people search for a way to lose as much weight as possible as quickly as possible.  Many people put on this weight as a result of too much fast food, but an Iowa science teacher is silencing the fast-food haters and showing that, if done right, fast food can actually lead to losing weight.  As a part of a class experiment, John Cisna embarked on the hypothesis that a person could end up in better shape after eating McDonald’s every day, three meals a day. This included the healthier options as well as Big Mac’s and French fries on the daily. Cisna’s students were tasked with planning his meals—he could eat no more than 2,000 calories a day and had to stay within the FDA’s daily recommendations for fat, sugar, protein, carbs, and a number of other nutrients.  He also started walking for 45 minutes a day.

Even though this sounds like the beginning of Supersize Me, a documentary by Morgan Spurlock who packed on 24 pounds in the course of a month by eating McDonald’s every day, Cisna had experienced very different results. By the end of the six months, the science teacher had lost 60 pounds—a virtual dream come true for grease and fast-food loving Americans.  So what does Cisna have to say about his experiment?  He says his results show that individuals should take individual accountability and responsibility for their food choices and not be so quick to blame fast food restaurants for their weight.

Even though Cisna does not recommend the diet for everyone, he says the experiment has changed his life for the better.  So, next time you’re eating a Big Mac, you can actually tell people you’re on a new health kick.

 

No pain no gain in the race for the fountain of youth

The key to longevity has been linked to many things over the years, from this lady who claims booze is her secret, to the more traditional approach of living a healthy lifestyle by working out and eating well.

Chillies

A recent study out of China now links longevity to eating spicy food. The study found a slightly lower risk of dying young related to eating spicy foods frequently. Basically, for those looking for the elusive fountain of youth, the answer very well may be pain. If you want to live longer, you could live in pain busting your butt to be healthy at the gym, or while enduring copious amounts of painfully tasty spicy food.

The study observed 500,000 people in China between the ages of 30 and 79 over the course of seven years. By the end of the study, approximately 20,000 had passed away. Ultimately, the study found that those who ate spicy food a few times a week were 10% less likely to die during the study, compared to those who ate it less than once a week.

Scientists say there is not enough research as of yet to identify a definitive link and cause between the two. However, it is speculated that it could be attributed to the link between eating spicy foods and lower inflammation, improve breakdown of fat in the body, or modified stomach bacteria.

So, start throwing back more cold ones and enjoy something muy caliente in the name of health.

NASA discovers closest thing to Earth 2.0, yet does not confirm nor deny alien life

NASA‘s Kepler space telescope has discovered a planet that is widely considered the most Earth-like of any to date: Keplershutterstock_183837821 452b. Kepler 452b is just one in a large series of discoveries by Kepler, which has been in use since 2009 and has since discovered 5000 potential planets.

Kepler 452b is estimated to be about 6 billion years old, making it 1.5 billion years older than Earth, and is 60 percent larger in diameter. Scientists believe that it has the same rocky exterior as Earth. These factors combined would mean Kepler 452b has twice the gravity of earth, meaning a visit to the planet would make you weigh twice as much. So to those on the weight-loss grind, 0 out of 10 would not recommend visiting this planet. It orbits its star at about the same distance and speed as earth and sun, which makes for a very good possibility of having liquid water on its surface.

In regards to whether this new Kepler discovery is inhabited by life, like Earth, John Grunsfeld, NASA’s science mission chief, says we are “one small step in answering that question” which does not necessarily deny the existence of other life forms, and is therefore a big win for the alien enthusiast in your life. Basically, if you’ve not yet found your earthly Bizarro world, we might be one step closer to finding it out in space 1,400 light-years away. Seinfeld fans rejoice.

You Won’t Like Me When I’m Hangry: The Science Behind Hunger Induced Anger

shutterstock_226371208Everyone has felt it – the short temper that creeps over you when the waiter seems to serve every other table before so much as taking your order; when your first meal of the day is the free samples at Costco and the person in front of you takes the very last artisan meatball; when the fast food drive-though could not move ANY slower. This phenomenon of hunger-induced anger has not gone unnoticed by anyone whose ever gone to the supermarket with an empty stomach.

This state of being “hangry” – a word invented to describe the feeling of being hungry-angry – was previously an unexplained correlation. Now, however, researchers the University of Sydney seem to have found an evolutionary explanation for this feeling. In her book “Don’t Go Hungry for Life,” Amanda Salis explains the chemical mechanisms that lead to this sensation.  Our glucose levels drop as time passes since our last meal. When this occurs, our bodies are alerted to produce other chemicals, most notably, adrenaline (also known as epinephrine) and cortisol. These are stress hormones, the same that one would feel in a fight-or-flight scenario. It’s these hormones that increase ones irritability.

Before you get frustrated at all of this unnecessary stress your body is putting you through, realize that this stress has not always been unnecessary. This chemical reaction originally served as a survival mechanism for early humans. Salis explains how this could have developed over the course of human evolution, noting “if hungry organisms stood back and graciously let others eat before them, their species could die out.” Species that exhibit this stress response, therefore, are more likely to survive.

So next time your “hanger” has you ready to become an uncontrollable rage monster, remember that it’s only natural- natural selection that is.

Monkey See, Monkey (Wired to Another Monkey’s Brain at NYU) Do

shutterstock_295328978At the risk of sounding like a pitch for a bad Syfy Channel remake of the “Planet of the Apes,” researchers at Duke University announced they have successfully wired monkey brains together in order to create what they are calling “organic computers” or, “brainets.” Researcher, Miguel Nicolelis, who apparently takes the phrase “two heads are better than one” too literally, led the team of neurobiologist who created the monkey network in order to see if two brains could collaborate in order to complete tasks more efficiently.

The study was conducted by implanting electrodes into the brains of several monkeys. By picking up the signals from several hundred electrodes, researchers were able to monitor about 3,000 neurons. Monkeys were then interconnected to a computer which displayed a digital monkey arm on the screen. The monkeys were then assigned the task of directing the digital monkey arm to a target. If successful, the monkeys were rewarded with juice.

Additional studies were conducted using four rats as well. These rats were directly wired to each other so that neural information could be passed from one rat to another when one of those rats responded to a stimulus. According to researchers, these ratborgs were at times able to perform certain tasks better than a single, un-wired rat would.

Nicolelis states that the purpose of the study was to explore the possibility of accelerating rehab for those suffering from neurological damage. Because of the long and difficult process these patients have to go through in order to relearn basic motor skills, Nicolelis believes that if a healthy brain could be wired to a recovering patient, then the healthy brain could essentially communicate with the damaged brain and teach it how to regain these motor skills.

UT researchers get rats addicted, then un-addicted, to drugs and alcohol

shutterstock_2180800While keeping Austin weird, researchers at the University of Texas at Austin have trained rats to be alcoholics and addicted to cocaine, and thereafter proved a link between the blood pressure medication, isradipine, and a decrease in addiction.

Scientists classically conditioned rats to associate different colors of rooms with a dose of alcohol or cocaine, and found when given the choice, rats would gravitate toward the color room associated with the substance. However, when isradipine was introduced to the mix, the rats steadily began to show no preference for the rooms with doses of alcohol or cocaine.

According to the lead researcher of the study, Hitoshi Morikawa, associate professor of neuroscience at the University of Texas, “The isradipine erased memories that led them to associate a certain room with cocaine or alcohol.”

It used to be believed that people who became addicted to drugs simply lacked the willpower to stop using, which is pretty consistent with the drug-laden bum stereotype we grow up believing and which currently sprinkle the streets outside many a shoe-box-sized apartment in cities.

However, it is now scientific belief that environmental cues, such as sights, sounds and the dingy places you go to use drugs, can facilitate a relapse. Scientists now believe addiction has a lot more to do with classical conditioning than merely a lack of willpower.

The researchers found that the isradipine rewires the brain a bit, helping the addicted rat to dissociate room color with wanting to use drugs or alcohol, essentially helping them forget to be addicted.

Isradipine is already FDA approved as a high blood pressure treatment, which will likely make clinical testing easier, and could potentially help human addicts in the near future. However, it is unclear as of yet whether isradipine will be as effective for humans as it was the rats. Regardless, great news for the alcoholic rat in your life.

Ancient Caterpillars “Mustard” Up the Courage in Bitter Battle

shutterstock_127958429Odds are, if you had any kind of a childhood, you have probably heard of Colonel Mustard. However, rather than being a clean cut military man from an old board game, a new study from the Proceedings of the National Academy of Sciences, PNAS, Colonel Mustard was actually a glucosinolate, a sharp tasting chemical, produced by ancestors of today’s Brassicale order which includes wasabi, horseradish, mustard, cabbage, and kale.

Way back in the day, like 90 million years ago, caterpillars and Brassicales were involved in what the study calls an “evolutionary arms race.” As a result of caterpillars feeding on the ancient plants, these plants developed glucosinolates to fend off the hungry critters. However, rather than finding new plants to feed on, these caterpillars fought back by developing their own chemical defenses against the glucosinolate toxins.

Scientists claim that this chemical evolutionary battle occurred three times in the past 90 million years. The most surprising part of the discovery is not that plants and bugs co-evolved by making small changes to their genes, but rather that they co-evolved by creating entirely new copies of their genes, a process that is said to be rare in the natural world.

Luckily for us, these ancient chemical battles lead to plants developing highly complex glucosinolates that give wasabi, horseradish, mustard, cauliflower, and radishes their distinct flavors. So the next time you open your refrigerator, be sure thank the “seasoned” caterpillar veterans.

The Secret Life of the European Neanderthal

shutterstock_164724497We all have our scandalous secrets and regrettable moments – problems that turn out to be as old as humans themselves. As much as your judgmental grandmother insists that you brought a less evolved subspecies of human to dinner, this hasn’t actually happened for 40,000 years, give or take. Still, this is far more recent than scientists previously thought. A recent discovery of the jaw bone of a man who lived an estimated 40,000 years ago in Europe contained a surprising revelation. Found in the Perstera cu Oase cave in Romania, DNA evidence indicated that this man had a Neanderthal ancestor in his recent past, as recent as four to six generations back in his family history.

Up to this point, anthropologist estimated that the most recent interbreeding between Neanderthals and modern humans occurred 50,000 to 60,000 years ago in the Middle East, shortly after modern humans migrated out of Africa. Until this recent discovery, there was no evidence that this mingling continued in Europe, after modern humans migrated out of the Middle East. This revelation gives us more evidence into the social dynamics of early humans and more clues into the mystery of what happened to the Neanderthals, as Neanderthal DNA was quickly lost from the human genome a few generations after this “Oase Man” (as he is now referred to) lived.

If you’re quick to judge the Oase Man for his scandalous family history, take a look at your own lineage. Modern humans alive today have 1-3% Neanderthal DNA. Although, if your grandma has anything to say about it, some have retained a little more than others.

Robot Skin, Because You’re Worth It

tattooCyborgs and other theories of humans hybridizing with robot parts have been a common theme for decades, dealing with how technology and humans will ultimately mix. However, it is looking more and more as if, instead of body parts being replaced by robots, we will simply tattoo the mechanics onto our bodies. Tattoos may not be the most ideal method for wearable technology for everyone, however the stick-on and temporary wearable devices that are currently in development may change some people’s minds.

Scientists are working on wearable technology that is as simple as placing a sticker or temporary tattoo onto the desired skin area. The tattoo bends and stretches with the skin, transmitting information back to the wearer. MC10, a company that specializes in wearable technology, announced progress in the BioStamp system. The BioStamp device is the size of a quarter and as thin as the skin it is placed on. The purpose of the device is to monitor and report heart rate, body movement, and other biometric data for health.

In another sector of tattoo technology, L’Oréal is working with scientists to create a patch that will work with their health and beauty products to better understand and treat skin conditions. The stickers can track blood flow and temperature via the sensors and report back to the researcher. The same research team is also working with the patches to control video games.

In a few years, the possibilities for wearable technology like the BioStamp and L’Oréal’s patch are endless. As mechanical devices shrink and storage capacity grows, the science community is looking forward to the medical and entertainment doors that can be opened. Perhaps our children will put a quarter into a vending machine and instead of the temporary tattoos we grew up with, a technology infused tattoo will come out with the latest video game already downloaded on it. Who knows?

You want the pain; you need the pain

shutterstock_40106719Researchers may just have discovered the gene that can keep you from feeling pain. No one wants to feel pain. Depending on its severity, it is uncomfortable, distracting, or debilitating. However, if you don’t feel pain at all, you may be headed for trouble.

Children typically learn very early on to avoid situations that will cause them pain because it is, well, painful. This is as it should be. Pain is just as necessary to human survival as insects are to ecology. The feeling of pain tells us that something is wrong. It could be external (hot surface) or internal (toothache). In either case, it is a warning that you should do something (take away your hand) or see someone (dentist) to find and eliminate the source of pain. In a very real sense, pain is the feeling that keeps us from doing stupid things or letting bad situations continue.

The pain-suppressing gene is called PRDM12, a protein that is present in the developing fetus that helps in growing pain-warning nerve cells. In some cases, however, the gene mutates naturally, and some people are born short of a few pain neurons. Researchers now believe that it may still be present in adults, keeping pain neurons from fully functioning. Theoretically, manipulating the PRDM12 gene may help suppress pain receptors for people who are in constant pain. The study was published in Nature Genetics on May 25, 2015.

The theory has yet to be put into practice, but it will be of great benefit for certain populations. People suffering from chronic and debilitating pain have bigger problems than a potential scalding from a carelessly placed hand. The pain they have is huge, and it is always there. It prevents them from functioning with any kind normality, and if manipulating a gene can help them cope with the pain, then it is a matter of weighing the risks against the benefits.
