New research shows that most people with ADHD have a disordered body clock, prompting disturbed sleep, sleep deprivation, and a worsening of ADHD symptoms. Experts discuss how fixing the body clock could lessen the impact of both ADHD and physical diseases that result from poor sleep.
A Real-Life Star Trek Tricorder
A real-life version of the Star Trek Tricorder, a non-invasive remote medical diagnostic machine, has won a major contest after passing multiple tests. Now it faces FDA scrutiny to go onto the market. Its developer discusses what the device is and how it could be used.
The causes of stuttering have long remained a mystery. Over time, people have been led to believe that stuttering can be caused by psychological issues or develop due to parenting style. But, experts are discovering that these beliefs may not be true. Recent research has started to develop the idea that stuttering is actually caused by a structural problem in the brain.
Dr. Scott Grafton, Professor of Psychological and Brain Sciences at University of California, Santa Barbara explains that diffusion MRI scanning has been used in research to discover that a large portion of the arcuate fasciculus was missing in seven of the eight stutterers, but it was present in all of the non-stutterers. The arcuate fasciculus connects two parts of the brain that allow for language function, so if these parts of the brain are not connected, an individual’s ability to perform classic language functions can be affected.
Another cause of stuttering in speech is related to issues of perception. Dr. Devin McAuley, Professor of Psychology and Neuroscience at Michigan State University states that individuals who have a difficult time discerning musical beats may also have a hard time picking up on natural speech rhythms, too. This inability to perceive beats may induce a stutter in an individual because they are not capable of timing their speech due to an issue in generating natural rhythms of language.
How can these new discoveries help doctors develop new treatments for those who suffer from a stutter? Dr. Roger Ingham, Professor of Speech and Hearing Sciences at University of California, Santa Barbara explains one new method of altering speech. It is called modifying phonation intervals (MPI) which is a treatment that trains people to reduce the frequency of very short intervals of phonation in order to create fluent speech. While MPI treatment works about twice as well as other speaking treatments, there is still plenty of research to be done in order to increase the effectiveness of treatments for stutters.

We all want to be happy yet the American culture appears to be experiencing a joy-deficit. While it is well known that some individuals suffer from a chemical imbalance in the brain that affects their ability to be happy, many people are not aware of the fact that they can change the happiness that they feel by creating it on their own.
Seeking joy is an important aspect of human life. Dr. Sonja Lyubomirsky, Professor of Psychology at University of California, Riverside and author of The How of Happiness and Myths of Happiness: What Should Make You Happy But Doesn’t, What Shouldn’t Make You Happy But Does explains that Americans have the opportunity to experience joy everyday, but many are overlooking the small ways to feel it. She believes that people spend too much time waiting for big moments, rather than taking advantage of the little moments to experience joy.
So, what can a person do to feel more joy? Dr. Alex Korb, neuroscientist at University of California, Los Angeles and author, The Upward Spiral: Using Neural Science to Reverse the Course of Depression, One Small Change At a Time states that it is possible for people to increase their serotonin levels on their own and provides a few ways, such as sitting in the sunlight, remembering positive memories, and partaking in simple exercises. Just by partaking in some of these activities, people have the possibility to experience a little more joy in their daily lives.

Melanoma carries a poor prognosis when it’s not caught early, but a common, inexpensive drug could boost the effectiveness of immunotherapy to treat it. Current immunotherapy treatments have a response rate of less than 35 percent but a study in the journal OncoImmunology finds that the addition of pan beta blockers increases it substantially. In the study, 70 percent of patients receiving pan beta blockers with immunotherapy were still alive after five years versus about 25 percent of those who did not receive them.
If you’re sick, other people can tell it with just a glance. Researchers writing in the journal Proceedings of the Royal Society B injected half of a group of people with bacteria that produce flu-like symptoms, then photographed all of the subjects two hours later. The pictures were shown for no more than five seconds each to another group who were able to pick out who was well 70 percent of the time.
Going to religious services can be good for your health. A study in the journal PLOS One finds that people who attend religious services at least once a week receive a substantial amount of protection against mortality. Even those who attended less frequently suffered less mortality than those who didn’t attend at all. Religious affiliation made no difference. Scientists say health behaviors can explain some of it—those who attend services are less likely to smoke or drink, and more likely to exercise and get health screenings.
And finally, scientists may have discovered why some women stay away from particular college majors or career paths—the perception that you have to be brilliant to succeed in them. Researchers say girls begin to associate “smartness” with boys by the time they’re six years old, and their study in the Journal of Experimental Social Psychology finds that those stereotypes persist over time. so women are less likely to think they’ll fit in if it takes being really smart to succeed.
Stuttering has been blamed even fairly recently on parenting, but new research has several new findings: a structural deficiency in the brain’s wiring in stutterers; an inability to perceive rhythms; and a much more successful way to treat stuttering. Experts discuss the new advances.
Surveys show that most Americans are less than happy, and seldom experience joy. Two experts discuss how even naturally glum people can manufacture joy.
Silence is no longer an answer. With movements like “Me Too” and “Times Up” surfacing all over social media and popular television, many women are beginning to take a stand against sexual harassment. Dr. Ashton Lofgreen, Assistant Professor of Psychiatry at Rush University, explains that in the past, there has been a perpetuated silence that discouraged women from speaking up, but now, people are recognizing that they are not alone in their experiences with sexual harassment. While many more women are opening up, there is still a lot of confusion behind what exactly constitutes sexual harassment.
So, how does one know if they have experienced sexual harassment? Dr. Cynthia Eller, Professor of Religion at Claremont Graduate University and author of The Myth of Matriarchal Prehistory: Why an Invented Past Won’t Give Women a Future, thinks that there are some general rules to follow that can help one address whether an action is sexual harassment. Besides understanding specific behaviors, Dr. Emily Grijalva, Assistant Professor of Organization and Human Resources at University of Buffalo, says that there is also a type of person to look out for: a narcissist. In a study done by Dr. Grijalva and her male cohorts, they found that there is a positive connection between narcissism and sexual harassment. While these are a few ways to identify behaviors or traits often associated with sexual harassment, there are other ways too.
It is possible to measure the chances that someone will commit an act of sexual harassment. Dr. John Pryor, Emeritus Distinguished Professor of Psychology at Illinois State University, states that there is a test that measures the willingness that an individual may have to behave in a sexually coercive or exploitative manner, to make gestures that are categorized as unwanted sexual attention, or participate in gender harassment. Despite the fact that these behaviors can be measured, issues of sexual harassment often slide under the radar, many times due to non-disclosure agreements and arbitration clauses that do not permit people to pursue cases within a court, according to Dr. Grijalva.
With the increase in which sexual harassment claims are being made, many people wonder about the possibility of these efforts going awry. But Dr. Lofgreen believes that these claims are fear-based and possibly another way of reinforcing the status quo that it’s better to not talk about these cases of sexual harassment. Similarly, Dr. Eller thinks that as long as a witch hunt is avoided, many people associated with these evolving movements will only benefit from coming forward.

Dr. Robert Lustig, pediatric endocrinologist, Professor of Pediatrics in the Division of Endocrinology at University of California, San Francisco, President of Institute for Responsible Nutrition, and author of Fat Chance: Beating the Odds Against Sugar, Processed Food, Obesity and Disease explains that generally people believe that obesity is a calorie problem: people eat too much and exercise too little. But, he states that there is something else at play here–the enormous increase in the consumption of dietary sugar across the country.
However, it is hard to place the blame on a lack of self-responsibility. Dr. Lustig explains that evidence shows sugar is addictive and it is capable of exciting the brain in a similar way that other substances of abuse do, too. Dr. Lustig believes there are two reasons sugar has become so prevalent in the human diet: first, sugar became cheaper, and second, the food industry put an emphasis on “low-fat”and “fat-free” diets that encouraged people to eat these foods that are higher in sugar.
The negative effects of sugar are not only seen through the increase in obesity, but also in the rise of diabetes which is increasing at a far quicker pace. Dr. Lustig states that this growth in diabetes is not just affecting those who are obese, it is affecting all people who consume sugar at a high rate. He further explains that diabetes is not about obesity, but that it’s about how our bodies metabolize what enters it and the damages that these bad foods cause in the process. In order to decrease the number of people being affected by diabetes and obesity, sugar consumption must go down.
