Travel experience is valued in globalized society. “Loves to travel” is tacked onto countless dating profiles.

Conventional wisdom holds that travel makes us well-rounded people. But what actually are the psychological effects of travel? 

New research suggests there's a dark side lurking underneath the well-established benefits of foreign experiences.

The Science of Animal CognitionOver the past several years, one of the biggest advances in our human understanding of doggie cognition has been the use of MRI machines to scan dog brains. MRI stands for magnetic resonance imaging, the process of taking an ongoing picture of what parts of the brain are lighting up through what external stimuli.Dogs, as any doggie parent knows, are highly trainable. This trainable nature makes dogs great candidates for MRI machines, unlike non-domesticated wild animals like birds or bears.

Through ongoing research, McGowan has found out a lot about animal cognition and feelings. In a study done in 2015, McGowan found that a human’s presence leads to increased blood flow to a dog’s eyes, ears and paws, which means the dog is excited.

As Smart as ChildrenAnimal psychologists have clocked dog intelligence at right around that of a two to two-and-a-half year old human child. The 2009 study which examined this found that dogs can understand up to 250 words and gestures. Even more surprising, the same study found that dogs can actually count low numbers (up to five) and even do simple math.

“Falsehood flies, and the Truth comes limping after it,” Jonathan Swift once wrote.It was hyperbole three centuries ago. But it is a factual description of social media, according to an ambitious and first-of-its-kind study published Thursday in Science.

By every common metric, falsehood consistently dominates the truth on Twitter, the study finds: Fake news and false rumors reach more people, penetrate deeper into the social network, and spread much faster than accurate stories.

“It seems to be pretty clear [from our study] that false information outperforms true information,” said Soroush Vosoughi, a data scientist at MIT who has studied fake news since 2013 and who led this study. “And that is not just because of bots. It might have something to do with human nature.”

Adults in the United States who binge drink are consuming even more alcohol per binging episode, according to a new study published Thursday by the US Centers for Disease Control and Prevention. Researchers analyzed data from the Behavioral Risk Factor Surveillance System over a six-year period and discovered that the annual number of binge drinks among adults who reported excessive drinking jumped on average from 472 in 2011 to 529 in 2017. That's a 12% increase.It's not just college kids. A new study says older adults binge drink, tooThe CDC defines binge drinking as five drinks or more for men or four or more for women on a single occasion. Binge drinking has serious health risks, according to the CDC, including car accidents, domestic violence, STDs, unintentional pregnancy, stroke, heart and liver disease.

In 2017, the number of binge drinks pear year among adult binge drinkers ranged from 320 per year in Massachusetts to 1,219 in Wyoming. The number of drinks among those who reported binge drinking increased in nine states -- Idaho, Indiana, Maine, Montana, New Jersey, New York, North Dakota, Ohio and Virginia -- while the number of drinks decreased significantly in Massachusetts and West Virginia.

About 30 percent of heart attacks, strokes and deaths from heart disease can be prevented in people at high risk if they switch to a Mediterranean diet rich in olive oil, nuts, beans, fish, fruits and vegetables, and even drink wine with meals, a large and rigorous new study has found.

The magnitude of the diet’s benefits startled experts. The study ended early, after almost five years, because the results were so clear it was considered unethical to continue.

The diet helped those following it even though they did not lose weight

I am a deluded throwback to carefree days, and in my attempt to raise a conscious, creative and socially and environmentally responsible child while lacking the means to also finance her conscious, creative and environmentally and socially responsible lifestyle forever, I’d accidentally gone and raised a hothouse serf. Oops.

Reich’s thesis is that some inequality is inevitable, even necessary, in a free-market system. But what makes an economy stable and prosperous is a strong, vibrant, growing middle class. In the three decades after World War II, a period that Reich calls “the great prosperity,” the G.I. Bill, the expansion of public universities and the rise of labor unions helped create the biggest, best-educated middle class in the world. Reich describes this as an example of a “virtuous circle” in which productivity grows, wages increase, workers buy more, companies hire more, tax revenues increase, government invests more, workers are better educated. On the flip side, when the middle class doesn’t share in the economic gains, it results over time in a downward vicious cycle: Wages stagnate, workers buy less, companies downsize, tax revenues decrease, government cuts programs, workers are less educated, unemployment rises, deficits grow. Since the crash that followed the deregulation of the financial markets, we have struggled to emerge from such a cycle.

What if the kid got it in her head that it was a good idea to go into public service, the helping professions, craftsmanship, scholarship or — God help her — the arts? Wouldn’t a greedier, more back-stabby style of early education be more valuable to the children of the shrinking middle class ­ — one suited to the world they are actually living in?

The study, which compares the traits of young people in high school and entering college today with those of baby boomers and Gen X'ers at the same age from 1966 to 2009, shows an increasing trend of valuing money, image, and fame more than inherent principles like self-acceptance, affiliation, and community. "The results generally support the 'Generation Me' view of generational differences rather than the 'Generation We,'

college students in 1971 ranked the importance of being very well off financially No. 8 in their life goals, but since 1989, they have consistently placed it at the top of the list.

"I see no evidence that today's young people feel much attachment to duty or to group cohesion. Young people have been consistently taught to put their own needs first and to focus on feeling good about themselves."

He and his team have shown, again and again, and in many different ways, that much of what biomedical researchers conclude in published studies—conclusions that doctors keep in mind when they prescribe antibiotics or blood-pressure medication, or when they advise us to consume more fiber or less meat, or when they recommend surgery for heart disease or back pain—is misleading, exaggerated, and often flat-out wrong. He charges that as much as 90 percent of the published medical information that doctors rely on is flawed. His work has been widely accepted by the medical community

for all his influence, he worries that the field of medical research is so pervasively flawed, and so riddled with conflicts of interest, that it might be chronically resistant to change—or even to publicly admitting that there’s a problem

he discovered that the range of errors being committed was astonishing: from what questions researchers posed, to how they set up the studies, to which patients they recruited for the studies, to which measurements they took, to how they analyzed the data, to how they presented their results, to how particular studies came to be published in medical journals

As a historian, I was influenced by E. H. Carr’s thinking about the past and present as part of a continuum that stretches into the future. In What is History? (1961), Carr argued that concern with the future is what really motivates the study of the past. As a teacher and political activist, I also strongly believe that schools should promote active citizenship as essential for maintaining a democratic society.

in an effort to survive, the NCSS has largely abandoned its commitment to these ideas, twisting itself into a pretzel to adapt to national Common Core standards and to satisfy influential conservative organizations that they are not radical, or even liberal. I suspect, but cannot document, that the organization’s membership has precipitously declined during the past two decades and it has increasingly depended financial support for its conferences and publications from deep-pocketed traditional and rightwing groups who advertise and have display booths.

No Child Left Behind (NCLB). Since the introduction of NCLB, there has been a steady reduction in the amount of time spent in the teaching of social studies, with the most profound decline noticed in the elementary grades.”

The study, published in the Lancet Diabetes and Endocrinology journal, looks only at data, correlating BMI with dementia diagnoses in general practice records and making allowances for anything that could skew the picture.

Dr Simon Ridley, from Alzheimer’s Research UK, said further work is needed. “This study doesn’t tell us that being underweight causes dementia, or that being overweight will prevent the condition,” he said.

“We haven’t been able to find an explanation,” said Qizilbash. “We are left with this finding which overshadows all the previous studies put together. The question is whether there is another explanation for it. In epidemiology, you are always left with the question of whether there is another factor.”

It is his latest effort to cripple the agency. Mr. Pruitt, who as Oklahoma’s attorney general described himself as “a leading advocate against the E.P.A.’s activist agenda,” said in an interview published in The Daily Caller last week that he would no longer allow the agency to use studies that include nonpublic scientific data to develop rules to safeguard public health and prevent pollution.

Opponents of the agency and of mainstream climate science call these studies “secret science.” But that’s simply not true. Peer review ensures that the analytic methodologies underlying studies funded by the agency are sound.

Some of those studies, particularly those that determine the effects of exposure to chemicals and pollution on health, rely on medical records that by law are confidential because of patient privacy policies. These studies summarize the analysis of raw data and draw conclusions based on that analysis. Other government agencies also use studies like these to develop policy and regulations, and to buttress and defend rules against legal challenges. They are, in fact, essential to making sound public policy.

5 Psychology Studies That Will Make You Feel Good About Humanity

When We're Grateful, We Want to Pay it Forward Caiaimage/Sam Edwards / Getty Images You may have heard in the news about "pay it forward" chains: when one person offers a small favor (like paying for the meal or coffee of the person behind them in line) the recipient is likely to offer the same favor to someone else. A study by researchers at Northeastern University has found that people really do want to pay it forward when someone else helps them — and the reason is that they feel grateful. This experiment was set up so that participants would experience a problem with their computer half way through the study. When someone else helped them fix the computer, they subsequently spend more time helping the next person with their computer issues. In other words, when we feel grateful f

When We Help Others, We Feel Happier

Plenty of studies have found correlations between higher social media use and poorer mental health, including depression, anxiety, feelings of loneliness and isolation, lower self-esteem, and even suicidality. But two new studies underline this reality by showing not just correlation, but causation—in other words, that tweaking your time on social media actually has measurable effects on mental health.

As the researchers expected, people who limited their social media use to 30 minutes felt significantly better after the three-week period, reporting reduced depression and loneliness, especially those who came into the study with higher levels of depression. Interestingly, both groups reported less FOMO and less anxiety in the end, which the team suggests may just be a resulting benefit of increased self-monitoring.

What’s also important to point out, but was not studied here, is that making any kind of comparison—not just to people who you think are more attractive or smarter, but also people who you think are less attractive or smart (or anything) than you—is linked to poorer well-being.

Science has been exploring the connection between happiness and longevity for some time. A 2011 analysis of nearly 4,000 Brits found those who said they felt content, happy or excited on a typical day were up to 35% less likely to die prematurely. In a 2016 study, a positive outlook was associated with longer life for nearly 4,000 older French men and women studied over 22 years.

According to research on the Positive Psychology Center website, striving for well-being will allow you to perform better at work, have better relationships, a stronger immune system, fewer sleep problems, lower levels of burnout, better physical health and -- you'll live longer.

"Happiness comes in different sizes and flavors," said cardiologist Dr. Alan Rozanski, a professor of medicine at the Icahn School of Medicine at Mount Sinai who studies optimism."There is the transient type, fed by such things as a walk in a park, spending time with a friend, or eating that ice cream you love," he continued. "But these feelings of happiness come and go."

A’s — once reserved for recognizing excellence and distinction — are today the most commonly awarded grades in America.

That’s true at both Ivy League institutions and community colleges, at huge flagship publics and tiny liberal arts schools, and in English, ethnic studies and engineering departments alike. Across the country, wherever and whatever they study, mediocre students are increasingly likely to receive supposedly superlative grades.

Analyzing 70 years of transcript records from more than 400 schools, the researchers found that the share of A grades has tripled, from just 15 percent of grades in 1940 to 45 percent in 2013. At private schools, A’s account for nearly a majority of grades awarded.

The research team performed brain scans on 24 college students and recent graduates, both before and after they spent 100 hours studying for the LSAT over a three-month period. The researchers also scanned 23 young adults who didn't study for the test. For those who studied, the results showed increased connectivity between the frontal lobes of the brain, as well as between the frontal and parietal lobes, which are parts of the brain associated with reasoning and thinking.

The study focused on fluid reasoning—the ability to tackle a novel problem—which is a central part of IQ tests and can to some degree predict academic performance or ability in demanding careers.

"People assume that IQ tests measure some stable characteristic of an individual, but we think this whole assumption is flawed," said Silvia Bunge, the study's senior author. "We think the skills measured by an IQ test wax and wane over time depending on the individual's level of cognitive activity."

Could the emotional connotations of words in literature be a kind of lagging economic indicator? According to scientists who analyzed a century’s worth of writing, they might: After using big-data techniques to document the frequency of sad and happy words in millions of books, the researchers concluded that the emotional mood of literature reflects the mood of the economy over the previous 10 years.

They then matched that against a well-known indicator called the “economic misery index” — the sum of inflation rates and unemployment rates — and found that literary misery in a given year correlated with the average of the previous decade’s economic misery index numbers.

“To me it confirms that we do have a collective memory that conditions the way we write, and that economics is a very important driver of that.”

Written by a pair of researchers from universities in Montreal and Madrid, it examined whether the study of economics made students more apt to lie for financial gain. The answer: a resounding yes.

By the rules of this game, it was always more profitable to report a green circle. There was no way for the decision to be generous and help the other guy get a better payday, so altruism shouldn't have been a factor. There was no way for the decision maker to get caught lying. And because the rules were transparent, the decision maker didn't even have to worry about whether the other guy might know they were lying. 

economics and business students lied a much more often than everybody else. As shown in the table below, just 22.8 percent of them honestly reported the colors of the flashing circles, even when it cost them that extra euro. More than half of humanities students, on the other hand, were honest. Same went for law students, who appeared to play against type

How did experts get it so wrong?

the primary problem is that nutrition policy has long relied on a very weak kind of science: epidemiological, or “observational,” studies in which researchers follow large groups of people over many years. But even the most rigorous epidemiological studies suffer from a fundamental limitation. At best they can show only association, not causation.

Instead of accepting that this evidence was inadequate to give sound advice, strong-willed scientists overstated the significance of their studies.
