There are so many harmful effects caused by smoking that it’s hard to decide where to start listing them. From health complications after surgery to brain damage, and even inflicting harm on our pets, the list can go on. Smoking is also believed to contribute to skin aging, and now a new study on twins shows that smoking can indeed cause premature wrinkling and other characteristics of accelerated aging.

Researchers scouted for twins at the annual Twin Days Festival, in Twinsburg, Ohio, to find pairs in which one twin smoked and the other didn’t, or both smoked, but with a five-year difference between initiation. They found 79 twins, of whom 57 were women, altogether with an average age of 48 years old. Close-up photos of each participants face were shown to a group of plastic surgeons, who had no knowledge of each participants’ smoking history. They were told to point out “specific components of facial aging” that were related to smoking, and 57 percent of the time, they were able to spot the smoking twin.

(Plastic and Reconstructive Surgery/American Society of Plastic Surgeons.)  The twin on the left is a non-smoker. The twin on the right smoked for 29 years, as seen by aging around the eyes.

(Above: The twin on the left is a non-smoker. The twin on the right smoked for 29 years, as seen by aging around the eyes.)

“Smoking makes you look old. That’s all there is to it,” Dr. Elizabeth Tanzi, a dermatologist at the Washington Institute of Dermatologic Laser Surgery, and who wasn’t involved in the study, told Reuters. Besides lung cancer, heart attacks, and strokes, just one more good reason to stop smoking is that it’s definitely making you look a lot older.”

The various indicators of aging that the surgeons found included: more sagging of the upper eyelids, baggier lower eyelids and bags under the eyes; more facial wrinkles, including lines between the nose and mouth, wrinkling of the upper and lower lips, and sagging chins. Signs of aging were most pronounced on the lower parts of the face, with those whose difference was more than five years showing even more signs, the researchers said.

(Plastic and Reconstructive Surgery/American Society of Plastic Surgeons.) Both twins smoked, however, the one on the right smoked for 14 years longer, as seen by more facial wrinkles.

(Above: Both twins smoked, however, the one on the right smoked for 14 years longer, as seen by more facial wrinkles.)

“It is noteworthy that even among sets of twins where both are smokers, a difference in five years or more of smoking duration can cause visibly identifiable changes in facial aging,” they wrote.

The results held true even when environmental factors, such as work stress, alcohol consumption, and sunscreen use were accounted for. They also said that they could not control for the effect of smoking on fat distribution. A U.K. study found that “smokers on average have a lower body mass index than non-smokers.”

Study author Dr. Bahman Guyuron suggested facial creams and plastic surgery for people who have already damaged their skin from smoking, but told Reuters that the goal of the study was to encourage people never to start in the first place. “We are hoping that by again emphasizing the harms that come from smoking, we can dissuade individuals from smoking … knowing how much it may damage their skin,” he said.

Smoking kills more than five million people each year around the world, and is responsible for nearly 87 percent of lung cancer deaths, according to the National Institutes of Health. It also increases the risk for cancer by up to 23 times for men and 13 times for women, according to the U.S. Cenetrs for Disease Control and Prevention, putting them at risk for cancer of the lips, oral cavity, esophagus, and many more.

What Is OCD?

Frequent, repetitive handwashing may be a sign of obsessive-compulsive disorder, or OCD.

Obsessive compulsive disorder, or OCD, is a mental disorder characterized by recurrent, persistent thoughts (obsessions) and ritualistic behaviors (compulsions) that interfere with a person’s daily life and relationships, according to the “Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition” (DSM-5).

People with OCD often realize their compulsive behavior is irrational, but they feel powerless to stop, since that only increases their level of anxiety.

The International OCD Foundation estimates that about 1 in 100 adults in the United States — and 1 in 200 children — has OCD. The condition often appears first during childhood or the teen years, and it tends to occur in men and women in roughly equal numbers. [Hypersex to Hoarding: 7 New Psychological Disorders]

Symptoms of OCD

OCD has many manifestations, but commonly, the obsessions of a person who has OCD are in some way linked to his or her compulsions. A child who obsesses about germs or contamination, for example, might compulsively wash his hands. Other common obsessions and compulsions include the constant need to “check” things, like that the front door is locked or the oven is turned off; an obsession with counting or arranging things in a particular order; or compulsive hoarding.

While OCD symptoms show up differently in each individual, those who have the disorder have at least one thing in common: Their obsessive-compulsive tendencies get in the way of everyday life. This is what separates OCD from the day-to-day anxiety and habits that are deemed “normal.”

A small amount of obsessive thinking or compulsive behavior is not necessarily a symptom of OCD; these are normal responses to real stress that serve a valuable purpose. The ability to foresee — and then worry about — possible dangers allowed early humans to take precautionary measures and survive difficult situations. But those with OCD may worry and compulsively perform “precautionary” behaviors even after they have determined that no danger exists.

Causes of OCD

Researchers have many theories about the causes of OCD in humans, ranging from childhood trauma to bacterial infection to genetics — the condition often runs in families. But scientists agree that OCD coincides with abnormalities in certain brain processes.

When exposed to threatening or frustrating situations, most people with OCD experience hyperactivity in the parts of the brain regulating external stimuli, including the amygdala — the part of the brain where danger is evaluated and processed — and the orbital frontal cortex, which performs cognitive processing and decision-making functions.

Serotonin is a neurotransmitter (a chemical that relays messages within the brain) that may play a part in OCD. People with the condition who take medication that modifies serotonin levels have fewer symptoms of OCD (see Treatments, below).

Diagnosis of OCD

While not all perfectionist behaviors are symptomatic of OCD, the disorder can become so severe and time-consuming that it becomes dysfunctional, preventing a person from normal day-to-day activities.

Only a qualified physician or mental-health provider can make an accurate diagnosis of OCD. The condition is often present with other mental-health disorders, such as depression, eating disorders or other anxiety disorders.

Treatment for OCD

There are several methods of treating OCD; most involve some kind of medication, psychotherapy or a combination of both.

Cognitive-behavioral therapy (CBT) has been shown to be effective in treating OCD by teaching the individual with the disorder to try a different approach to those situations that trigger their obsessive-compulsive behavior. One type of CBT, known as exposure and response prevention, can help people with OCD by teaching them healthy ways to respond when exposed to a feared object (dirt or dust, for example).

Selective serotonin reuptake inhibitor (SSRI) antidepressants are the medications most commonly prescribed for treating OCD. Anti-anxiety medication may also be prescribed.

Both types of medications may take several weeks to begin to work, according to the National Institutes of Health. In addition to side effects such as headache, nausea and insomnia, antidepressants have been shown to cause suicidal thoughts and behaviors in some people. People taking antidepressants need to be monitored closely, especially when starting their treatment.

Possibly one of the weirdest geological formations in the world

ANNALEE NEWITZ   http://io9.com/possibly-one-of-the-weirdest-geological-formations-in-t-1455456417

How did this happen? In Norway, there is a bizarre rock formation known as Kjeragbolten – Norway, which is a huge block of stone that has become lodged in a 984-meter-deep crevice over a gorgeous lake. It’s so sturdy that sheep like to stand on it — and so do humans.

According to Atlas Obscura:

The boulder itself is a 5-cubic-meter large block of stone suspended above 984-meter deep abyss. Despite its impressive appearance, it is easily accessible on foot without any special equipment. The whole of Kjerag mountain is a popular hiking area, and Kjeragbolten is a favorite photo spot.

Apparently, for some the thrill of standing on a boulder suspended between two cliffs isn’t quite enough, as Kjeragbolten has become a very popular spot for base jumpers to use when launching themselves into the air.

 

You can’t tell if someone is lying by reading their facial expressions

You can’t tell if someone is lying by reading their facial expressions

ROBERT T. GONZALEZ  http://io9.com/no-you-cant-tell-someone-is-lying-by-reading-their-mi-1454953226

So you’ve watched every single episode of Lie to Me and read every article from here to Mars on how to spot a fake smile and gotten pretty damn fantastic at spotting these fleeting, involuntary facial movements called microexpressions. You’re pretty much ready to bet the farm that you could spot a liar just by reading the clues written all over his stupid little liar face. Except no. No you can’t.

Microexpressions, as defined by psychologist Paul Ekman (who coined the term “microexpression,” basically wrote the book on the little bastards, and has been studying their use in detecting deception for going on half a century, now), are:

…very brief facial expressions, lasting between 1/25th and 1/15th of a second. They occur when a person either deliberately or unsconsciously conceals an emotion being felt. Any one of the seven emotions found to have a universal signal may appear in a micro expression: anger, fear, sadness, disgust, contempt, surprise and happiness.

Microexpressions therefore fall under the umbrella of “body language” (“nonverbals,” if you’re one for parlance), and are distinguishable in that they refer explicitly to the face and specific situations in which they’re likely to appear, viz. a situation where the emotion being felt is being either intentionally or unintentionally suppressed.

The big upshot is that microexpressions have the potential to reveal hidden sentiments (NB: They were first detected by psychologists Ernest Haggard and Kenneth Isaacs when the two of them were reviewing footage of people undergoing couple’s therapy. Go ahead and mull that one over for a second), and so could serve some use to people (law enforcement, parents, poker players, a suspicious spouse) who stand to gain from knowing where someone really stands on an issue – or, more specifically, whether that someone is lying. The whole premise of the showLie to Me, starring Tim Roth as an uncannily capable human lie-detector, is based almost entirely on research surrounding microexpressions.

It of course bears mentioning that while Lie to Me is a fictional TV show, microexpressions are 100% real. They’re difficult to detect, and even more difficult to analyze, but they’re real. But we repeat: you probably can’t use them like Tim Roth.

There are several reasons for this, but arguably the most important one is that a microexpression, on its own, can really only tell you that a person is experiencing some emotion. Even if you can accurately determine which emotion it is – let’s say it’s fear – all you can really say from your assessment is that the person you’re talking to is experiencing fear. Let’s say you’re interrogating someone suspected of murder and you pick up on their fearful microexpression. Are they afraid that you’re close to figuring out they committed the crime, or afraid of being interrogated by some creep who is goggling at their face the way a dog might stare at a rack of ribs?

The point being that context – situational context, emotional context, the context of your relationship with the person you’re scrutinizing – is incredibly important when reading someone’s microexpressions. The importance of context applies to the analyses of other forms of body language, too, by the way. According to Joe Navarroa former FBI counterintelligence agent and an expert on nonverbal cues, a person’s feet tend to be more accurate in revealing sentiments and intentions than her face. And loads more important than someone’s face or feet, on their own, is the concurrent reading of her entire body, which Navarro says “is constantly transmitting vital information.”

But even if you have been trained to pick up on every last one of a person’s corporeal clues, it remains incredibly unlikely that you are equipped to divine when they are or are not being deceitful. To quote Ekman, the pinoeering microagression researcher, again, this time from his book Telling Lies: “Most liars can fool most people most of the time.” That includes people who have been taught to spot body language.

“Our research,” he goes on to explain, “and the research of most others, has found that few people do better than chance in judging whether someone is lying or truthful.” His research has also shown, and I’m going to bold this, just so that I can refer to it easily when I see someone bring this up in the comments“that most people think they are making accurate judgments even though they are not.” Allow us to reiterate: YOU ARE NOT TIM ROTH.

Okay but so wait… like… what if you really CAN tell when people are lying? What if you really are Tim Roth? Well, then perhaps you are one of the “few exceptional people who,” Ekman claims, actually “can quite accurately spot deceit.”

And this is where things get a little weird.

Some years ago, Ekman teamed up with fellow UC San Francisco psychologist Maureen O’Sullivan to establish a research project that would not only investigate people’s ability to detect lies, but actively seek out “Truth Wizards” – that is, people able to identify deception in other people in at least 80% of standardized trials. “Although most groups, including police officers, CIA and FBI agents, lawyers, college students and therapists, do little better than chance,” said O’Sullivan in a 2004 statement, wizards can usually detect whether a person is lying, whether that lie is about an opinion, and “how someone is feeling about a theft.”

By 2004, “The Wizard Project,” had tested more than 13,000 people and O’Sullivan and Ekman had identified 31 wizards. By those figures, fewer than 25 people in 10,000 are good enough at detecting deception to merit wizard status.

But then, the fact that there are any wizards to speak of whatsoever is certainly surprising, is it not? This is the real question – are there, in fact, people who possess the uncanny ability to read fleeting facial expressions, hand gestures, or shifts in body weight and divine your true feelings, opinions, or knowledge on a subject? Could you really be Tim Roth?

A statistical critique of The Wizards Project by psychologists Charles F. Bond Jr. and Ahmet Uysal found O’Sullivan and Ekman’s findings to be statistically and methodologically suspect. “Analyses reveal that chance can explain results that the authors attribute to wizardry,” the researchers write in a 2007 issue of Law and Human Behavior. “Thus, by the usual statistical logic of psychological research, O’Sullivan and Ekman’s claims about wizardry are gratuitous.”

In the same issue of Law and Human Behavior, O’Sullivan cam to Ekman’s defense as well as her own with a perspective piece titled “Unicorns or Tiger Woods: are lie detection experts myths or rarities?” The piece takes Bond and Uysal to task, claiming misrepresentation or misinterpretation by the researchers’ of The Wizards Project and its findings.

The “lively debate” over Ekman and O’Sullivan’s work on deceit detection, is ongoing – and on the subject of microexpressions, in particular, Ekman remains a contentious figure. His efforts to teach microexpression-analysis to TSA Agents has produced uninspiring results. Boise State University psychologist Charles Honts, a former DoD polygrapher who was trained by Ekman and now specializes in the study of deception, claims that every one of his attempts to replicate Ekman’s experiments have failed. “There’s not a lot of science to back up Ekman’s claims,” said Jay Nunamaker, head computer engineer of the digital lie-detecting Embodied Avatar project, in an interview with WIRED published earlier this year. “Applying them to deception detection is a reach.”

In light of this contention, it is perhaps sufficient, in the debate over whether you are or are not capable of telling whether another person is lying, to refer to the title written by O’Sullivan in defense of her and Ekman’s Wizard Project findings: “Unicorns or Tiger Woods: are lie detection experts myths or rarities?” When an ability becomes so rare as to be confused with myth, it’s probably safe to assume you don’t possess it.

In brief: No. You are not Tim Roth.

Sistine Chapel: Facts, History & Visitor Information

‘The Creation of Adam’ is one of the nine ceiling panels in the Sistine Chapel depicting scenes from the book of Genesis.

The Sistine Chapel is a large chapel in the Vatican City. It is renowned for its Renaissance art, especially the ceiling painted by Michelangelo, and attracts more than 5 million visitors each year.

History

The Sistine Chapel stands on the foundation of an older chapel called the Capella Magna. In 1477, Pope Sixtus IV instigated a rebuilding of the chapel, which was then named for him.

The chapel is 40.23 meters long, 13.40 meters wide, and 20.70 meters high (about 132 by 44 by 68 feet) — reputedly, the dimensions of Solomon’s temple in Jerusalem, which was destroyed in A.D. 70. The chapel’s exterior is simple and unassuming, giving little hint to the splendid decoration inside.

Pope Sixtus IV commissioned celebrated painters, including Botticelli and Rosselli, to decorate the chapel. At this point, the Sistine Chapel’s ceiling was painted like a simple blue sky with stars.

In 1503, a new pope, Julius II, decided to change some of the Sistine Chapel’s decoration. He commanded artist Michelangelo to do it. Michelangelo balked, because he considered himself a sculptor, not a painter, and he was hard at work sculpting the king’s tomb. But Pope Julius insisted, and Michelangelo began work on his famous frescoed ceiling in 1508. He worked for four years. It was so physically taxing that it permanently damaged his eyesight.

More than 20 years later, Pope Clement VII commissioned Michelangelo to paint the giant fresco “The Last Judgment” behind the altar. The artist, then in his 60s, painted it from 1536 to 1541.

Michelangelo’s paintings

Ceiling

At the highest part of the ceiling, Michelangelo depicted nine scenes from Genesis, including “The Separation of Light From Darkness” at the altar end of the chapel to “The Drunkenness of Noah” at the other end. The most famous panels are “The Creation of Adam” and “The Fall of Man and the Expulsion from Paradise.” Images of prophets and pagan sibyls surround the panels, and twisting (and originally controversial) male nudes decorate the corners.

The Last Judgment

This fresco depicts the second coming of Christ, who is judging all mankind. The blessed are on the right and heading to heaven, while the damned are on the left and being sent to hell and tortured by demons. Major Biblical and Catholic characters appear in the scene, including Eve and several saints.

Secret images

In 1990, some physicians suggestedthat the flying-seat shape and figure of God in “The Creation of Adam” makes up an anatomically correct image of the human brain. In 2010, it was asserted that “The Separation of Light From Darkness” panel contains a human brain stem. Other theorists have suggested that Michelangelo depicted kidney imagery on the ceiling.  As a sculptor, Michelangelo was fascinated by the human form. He studied cadavers to get a better sense of anatomy, and would have been familiar with the human brain.

Painting the Sistine Chapel was an exhausting task, and Michelangelo’s relationship with the Catholic Church became strained doing it. Perhaps to depict his unhappiness, he hid two miserable-looking self-portraits in “The Last Judgment.”He painted his deceased face on Holofernes’ severed head and his ghoulish visage on Saint Bartholomew’s flayed skin.

Restoration efforts

A serious restoration of the Sistine Chapel began in 1980. Restorers spent 14 years reattaching fresco and cleaning it. They also removed some of the “modesty drapes” that had been added to Michelangelo’s work.

The restoration was extremely controversial. Some critics claim that the restoration removed an intentional second layer of paint, and that Michelangelo had intentionally used darker, more shadowy hues to give the figures depth. Others say that the restoration was essential for keeping the masterpiece intact and reviving the brilliancy of Michelangelo’s palette.

Papal use

The chapel is more than an artistic masterpiece; it is a place of crucial religious activity.  Since 1492, the chapel has been the site where the College of Cardinals gathers to elect a new pope.  The chapel has a special chimney that is used to broadcast the cardinals’ voting status. White smoke indicates that a new pope has been elected, while black smoke signals that no candidate has received a two-thirds majority.

Visiting the Sistine Chapel

Tickets: To visit the Sistine Chapel, one must purchase an admission ticket to theVatican Museums. As of 2013, adult tickets are 16 euros ($22). There are reduced options for youth, students, clergy and some others. There are selected free admission days throughout the year, including the last Sunday of each month. Because lines can be extremely long, it may save time to purchase a ticket online.

Hours: The Vatican Museums are open Monday through Saturday and the last Sunday of each month. Typically, the ticket office is open from 9 a.m. to 4 p.m., and the museums close at 6 p.m.

Restrictions: There are a variety of restrictions at the Vatican Museums, including no alcoholic drinks, immodest clothing, flash photography, or touching the works of art. All photography and filming is forbidden in the Sistine Chapel.
