A large new study spearheaded by researchers with the National Institute on Aging that involved scientists from more than 50 different institutions worldwide — including 23andMe — has found new genetic risks for Parkinson’s disease.
Published in this week’s Nature Genetics, the study is significant for both its size and its findings. It is the largest Parkinson’s genome wide association study (GWAS) ever done, looking at more than seven million variants in about 13,000 patients with the disease. The researchers used the data from more than 100,000 people without Parkinson’s who were used as controls. 23andMe contributed data from more than 4,000 of our customers with Parkinson’s and about 62,000 without the disease who all consented to participate in research.
The popular media portrays psychology in a variety of ways, from the reasonably accurate way that neuroscience is discussed in the TNT crime drama, Perception, to the silly but enjoyable use of “telepathy” in the USA network comedy Psych (now only shown in reruns). However, as readers of Psychology Today know, there are many practical applications of psychology in areas such as advice, mental health, and relationships. People seek interventions in the form of psychological counseling, guidance, psychotherapy, and help with substance abuse, couple, or family problems.
Without psychological research, these applications to treatment would not be possible. In addition, psychologists study a range of problems in basic science, such as the role of the brain in behavior, changes in the mind and body in development, processes of learning, memory, sensation and perception, and the ways that people think about others and the world in areas such as social cognition, attitudes, and stereotyping.

He was in the process of building what is now a $16 million trendy data-driven dining startup called Dinner Lab. Many would have loved to trade spots with him. Things were happening fast.
But he wasn’t able to focus in conversations. He was often overcome with an odd, out-of-reality sensation where he would watch people’s mouths move, but couldn’t concentrate on their words.
Bordainick had fallen into that perfect maelstrom of stress, anxiety and too much to do. He had hit that infamous and clichéd “wall.”
Hassan al-Zeyada has spent decades counseling fellow residents of the Gaza Strip who experience psychological trauma. Now, as he prepares to aid his neighbors after a new round of combat and carnage, he has a challenging new patient: himself.
An Israeli airstrike demolished Dr. Zeyada’s family home on July 20, killing six close relatives, including his mother and three of his brothers.
“You try to help the people with their suffering,” the doctor said recently in his Gaza City living room, lined with psychology textbooks. “It’s totally different when you have the same experience.
Late on Monday, the Broad Institute, a biomedical research center, announced a $650 million donation for psychiatric research from the Stanley Family Foundation — one of the largest private gifts ever for scientific research. It comes at a time when basic research into mental illness is sputtering, and many drug makers have all but abandoned the search for new treatments.
Despite decades of costly research, experts have learned virtually nothing about the causes of psychiatric disorders and have developed no truly novel drug treatments in more than a quarter century. Broad Institute officials hope that Mr. Stanley’s donation will change that, and they timed their announcement to coincide with the publication of the largest analysis to date on the genetics of schizophrenia.
Your beliefs about the way you think can shape your life in surprising ways. A spate of recent findings suggest that targeting such metacognition can help relieve mood and anxiety disorders, and it may even reduce symptoms of psychosis.
Metacognition often takes the form of a value judgment about one’s thoughts, such as “It’s bad that I overanalyze everything.” Research has shown that these metacognitive beliefs can play an important role in obsessive-compulsive disorder, depression and generalized anxiety disorder, among others. In particular, they may matter more than the way we frame situations in our mind, such as by focusing on the negative aspects of a life event. That framing, called cognitive appraisal, is typically addressed in psychotherapy, but metacognition is not, perhaps to the patient’s detriment, explains psychologist Jennifer L. Hudson of Macquarie University in Australia.
An organizational psychologist seeks to understand human behavior in organizational settings and applies behavioral principles and research findings to bring about change in these settings. Thus, they need to know: how groups function; negotiation strategies, problem solving techniques, and group cohesion methods; and, how to increase motivation and improve workplace performance.
A psychology MBA or other organizational psychology masters program prepares you to meet these expectations.
Researchers have discovered trends in the way that we perform every major action on Twitter—favoriting, updating, sharing, and following. And there’s even an interesting bit of psychology behind what makes Twitter so attractive in the first place. Here’s a look at the psychology of Twitter: what makes us follow, favorite, share and keep coming back for more.
A study published by the Association for the Advancement of Artificial Intelligence sought to put our myriad favoriting methods into categories.
Facebook has been playing with its users' emotions, and now a lot of people are upset.
For one week in 2012, hundreds of thousands of Facebook users were unknowingly subjected to an experiment in which their news feed was altered to see whether certain kinds of content made users happy or sad.
The research that resulted from that experiment, which was published in an academic journal this month, said emotions appeared to be contagious: If users saw happier posts from friends in their Facebook news feed, they were more likely to post their own happy updates. Sad updates appeared to have a comparable effect.
In other words, the study seems to show you are what you eat, as the saying goes -- except in that metaphor, you usually get to choose what you put in your mouth.We were concerned that exposure to friends' negativity might lead people to avoid visiting Facebook.- Adam D.I. Kramer, Facebook data scientist
Now, Facebook, which uses a secret algorithm to control what it shows users on its popular news feed, faces another round of allegations that the world's largest social-media network is being a little too creepy and manipulative.
After the study started to receive widespread scrutiny on the Web, Adam D.I. Kramer, a data scientist at Facebook and one of the study's authors, wrote in a post Sunday: "In hindsight, the research benefits of the paper may not have justified all of this anxiety."
Kramer added that he and the paper's coauthors were "very sorry for the way the paper described the research and any anxiety it caused."
You probably heard the phrase growing up: “It’s better to give than to receive.” Well, the University of Illinois just proved this to be true — at least, if you’re an adolescent.
Their study discovered that 15-16 year-old students who invest energy in pro-social activities such as giving their money to family members or serving a charity are less likely to suffer any level of depression than those who get a bigger thrill from taking risks or keeping the money for themselves.
The university researchers detailed their findings in the Proceedings of the National Academy of Sciences. The study focused on the ventral striatum, a region of the brain that regulates feelings of pleasure in response to rewards. Previous studies revealed that ventral striatum activity tends to be more vivid in adolescence, suggesting that teens experience the pleasure of rewards more intensely than younger kids or adults. In short, during the teen years, everything’s exaggerated. Adolescence is a time of expanded risk-taking — and this can be both good and bad, depending on the young person, suggests Illinois psychology professor Eva Telzer, who led the study. Why is this? Depressive symptoms tend to increase during teen years, Dr. Telzer reports. So, kids may respond by taking foolish risks…or they can risk involvement in an altruistic cause they believe in, and gain great satisfaction, hence warding off natural depression.

A study recently posted in the United States National Library of Medicine has linked air pollution with the development of neurological and behavioral health problems. Specific conditions that the study links pollution to include: cognitive decline, autism, schizophrenia, and depression.
Although the study involved mice, researchers concluded that, “Our findings suggest alteration of developmentally important neurochemicals and lateral ventricle dilation may be mechanistically related to observations linking ambient air pollutant exposure and adverse neurological/neurodevelopmental outcome in humans.” In other words, the biological effect of pollution in mice is likely to be similar to what occurs in humans.
The mice in the study were exposed to air samples similar to what is found in Los Angeles, Atlanta, New York City, and Boston. Following the exposure, the mice developed permanent inflammation and a specific neurotransmitter that is typically found in patients with schizophrenia or autism.

Sports injury prediction has previously relied upon physiological parameters but this research into Swedish premier league and international footballers focuses on the psychological factors involved in injury prevention and recovery.
In an interesting paper published in 2013 (Journal of Sport Rehabilitation(Ivarsson, Johnson & Podlog, 2013 and discussed here), Andreas Ivarsson and Urban Johnson from Halmstad University discuss the relevance of psychological factors on a footballers’ level of injury susceptibility and recovery.

Scientists have discovered a part of the human brain that enjoys eternal youth.
Researchers said the latest findings show that at least one part of the human brain stays cognitively intact, regardless of age.
“Our studies have found that older and younger adults perform in a similar way on a range of visual and non-visual tasks that measure spatial attention,” researcher Dr. Joanna Brooks, who conducted the study as a Visiting Research Fellow with the University of Adelaide’s School of Psychology and the School of Medicine, said in a news release.

Facebook is hardly the only web company to use its power over what users see for the sake of research. In a blog post Monday (thanks to UNC sociologist Zeynep Tufekci for the link), OkCupid’s Christian Rudder laid out three separate experiments the company has run on users.
What are we to make of manipulations like these? The findings are at least interesting.
When it comes to fighting suicide, knowing who is at risk can be tricky and, moreover, a very subjective process. Scientists at Johns Hopkins Medicine are trying to bring a level of objectivity into the search for those at high risk of attempting suicide – in the form of a simple blood test.
In a new study published in the American Journal of Psychiatry, researchers say they have found something of a common denominator in people who have committed suicide or those with suicidal thoughts or attempts. The key? A unique genetic mutation in the gene SKA2, which is thought to play an important role in the way our brains handle stress. Not everyone at risk of suicide has the genetic signature, but when people do have this mutation, their likelihood of attempting suicide was found to be extremely high compared to the rest of the population.
What does the academic field that has brought us Freudian theories have to do with the social network that popularized hashtags and play-by-play updates of Sunday brunches?
More than you would think. We want to know what will motivate our followers to act -- and psychology can help you find out just that.
I’ve been monitoring and publishing to HubSpot’s Twitter account for the past couple of months. During this time, I've noticed that certain types of tweet copy elicit higher numbers of clicks and engagement -- and these types of copy align with several prominent psychological theories.
To help you get your followers to better engage with your brand on Twitter, let's dive into four essential psychological theories.
Two interesting developments in telemedicine punctuated the runup to Independence Day celebrations last week. CMS proposed adding more telemedicine codes that can be reimbursement, primarily in the realm of psychotherapy and psychoanlysis. Humayun Chaudry, CEO of the Federation of State Medical Boards, said the group is readying a compact that would make it easier to practice medicine across state lines with participating states. He expects the proposal to be ready to be reviewed by state medical boards at the end of the summer.
Telemedicine startup and DreamIT Ventures accelerator grad 1DocWay works with physician networks and psychiatric hospitals to provide telepsychiatry services for Medicare and Medicaid patients. For co-founder and CEO Samir Malik, every development is reason for encouragement. Of the two proposals, the compact from the Federation would have the biggest impact, if it succeeds. Although the CMS proposal would have a negligible impact on 1DocWay’s sales, it’s certainly a positive step.

The first systematic international review of childhood vaccinations led by researchers from the University of Sydney has found no evidence of a link to the development of autism or autism spectrum disorders (ASDs).
The comprehensive review, published in medical journal Vaccine, examined five cohort studies involving more than 1.25 million children, an additional five case-control studies involving more than 9,920 children obtained via systematic searches of international medical databases MEDLINE, PubMed, EBASE and Google Scholar up to April 2014.
Both the cohort and case-control studies revealed no statistical data to support a relationship between childhood vaccination for the commonly-used vaccines for measles, mumps, rubella, diphtheria, tetanus and whooping cough and the development of autism or ASDs.
Three to six months after becoming parents, a quarter of fathers and nearly half of all mothers exhibit signs of clinical depression, according to a study published in the Journal of the American Medical Association. During the first five years of parenthood, both mothers and fathers report higher levels of dissatisfaction with their lives and a diminishment in the size of their network of family and friends. "A 2009 study in the Journal of Personality and Social Psychology found that the transition to parenthood is linked to reduced happiness in the marriage and more negative behavior during spousal conflict."
Gallup just released its survey on happiness around the world. The polling company looked at 138 countries. Here are the nations that ranked high in residents experiencing “a lot of positive emotions,” plus a few not-as-happy countries. We asked Eric Weiner, author of the “The Geography of Bliss ,’’ to share insights on a few of them. And here’s more global “Happy,’’ if you want it.

In study published today in Science, researchers at NYU Langone Medical Center show for the first time that sleep after learning encourages the growth of dendritic spines, the tiny protrusions from brain cells that connect to other brain cells and facilitate the passage of information across synapses, the junctions at which brain cells meet. Moreover, the activity of brain cells during deep sleep, or slow-wave sleep, after learning is critical for such growth.,
