Are E-cigarettes Leading More Kids to Smoke?

Today, thanks to decades of educational efforts about the serious health consequences of inhaled tobacco, fewer young people than ever smoke cigarettes in the United States. So, it’s interesting that a growing of number of middle and high school kids are using e-cigarettes—electronic devices that vaporize flavored liquid that generally contains nicotine.
E-cigarettes come with their own health risks, including lung inflammation, asthma, and respiratory infections. But their supporters argue that “vaping,” as it’s often called, might provide an option that would help young people steer clear of traditional cigarettes and the attendant future risks of lung cancer, emphysema, heart disease, and other serious health conditions. Now, a new NIH-funded study finds that this is—pardon the pun—mostly a pipe dream.
Analyzing the self-reported smoking behaviors of thousands of schoolkids nationwide, researchers found no evidence that the availability of e-cigarettes has served to accelerate the decline in youth smoking. In fact, the researchers concluded the opposite: the popularity of e-cigarettes has led more kids—not fewer—to get hooked on nicotine, which meets all criteria for being an addictive substance.
Creative Minds: Helping More Kids Beat Anxiety Disorders

While earning her Ph.D. in clinical psychology, Dylan Gee often encountered children and adolescents battling phobias, panic attacks, and other anxiety disorders. Most overcame them with the help of psychotherapy. But not all of the kids did, and Gee spent many an hour brainstorming about how to help her tougher cases, often to find that nothing worked.
What Gee noticed was that so many of the interventions she pondered were based on studies in adults. Little was actually known about the dramatic changes that a child’s developing brain undergoes and their implications for coping under stress. Gee, an assistant professor at Yale University, New Haven, CT, decided to dedicate her research career to bridging the gap between basic neuroscience and clinical interventions to treat children and adolescents with persistent anxiety and stress-related disorders.
Making the Connections: Study Links Brain’s Wiring to Human Traits

For questions about why people often think, act, and perceive the world so differently, the brain is clearly an obvious place to look for answers. However, because the human brain is packed with tens of billions of neurons, which together make trillions of connections, knowing exactly where and how to look remains profoundly challenging.
Undaunted by these complexities, researchers involved in the NIH-funded Human Connectome Project (HCP) have been making progress, as shown by some intriguing recent discoveries. In a study published in Nature Neuroscience [1], an HCP team found that the brains of individuals with “positive” traits—such as strong cognitive skills and a healthy sense of well-being—show stronger connectivity in certain areas of the brain than do those with more “negative” traits—such as tendencies toward anger, rule-breaking, and substance use. While these findings are preliminary, they suggest it may be possible one day to understand, and perhaps even modify, the connections within the brain that are associated with human behavior in all its diversity.
New Prize Celebrates Biology Breakthroughs

(in order as listed below)
The brand new $3 million Breakthrough Prize in the Life Sciences [1] delivered a very nice reward and well deserved recognition to eleven exceptionally creative scientists who have devoted their careers to biology and medicine. And, with five awards to be given each year, I hope this inspires other life scientists to embark on innovative and high-risk endeavors.
For this inaugural round, I’m proud to say that nine of the eleven winners were NIH grant recipients—some for more than three decades. Now, you may not have heard of most of these scientists. Quite frankly, that’s a shame. These folks have discovered fundamental principles of biology—everything from cancer causing genes to techniques for creating stem cells. These discoveries have boosted our understanding of health and disease, and led to the development of many drugs and therapies.
So these individuals really should be household names—and more of that kind of recognition would be a good thing to inspire youth to explore careers in science. In the United States, virtually everyone can list names of multiple movie stars and athletes, but two-thirds of Americans can’t name a single living scientist [2].
