A new study shows genomic differences in head and neck cancers caused by infection with the human papillomavirus. In addition, researchers have uncovered new smoking-related cancer subtypes and potential new drug targets, and found numerous genomic similarities with other cancer types. Together, this study's findings may provide detailed explanations of how HPV infection and smoking play roles in head and neck cancer risk and disease development, and offer potential diagnostic and treatment directions.

Play may seem like fun and games, but new research shows that specific kinds of play are actually associated with development of particular cognitive skills. Data from an American nationally representative study show that children who play frequently with puzzles, blocks, and board games tend to have better spatial reasoning ability. Being able to reason about space, and how to manipulate objects in space, is a critical part of everyday life, helping us to navigate a busy street, put together a piece of furniture, even load the dishwasher. And these skills are especially important for success in particular academic and professional domains, including science, technology, engineering, and math (STEM).

When donating blood, plasma, human tissue or any other bodily sample for medical research, most people might not think about how it's being used. But if you were told, would you care? A new study indicates that most people are willing to donate just knowing that their contribution is going toward research. But, when specific scenarios are brought into the equation, that willingness changes.

Mobile apps have proved to be valuable educational tools, but laboratory instructors thus far have been limited to using mobile devices only for virtual laboratories with simulated experiments. Now, researchers have developed a series of mobile applications that allow students to remotely interact with real data and equipment in real laboratories. Students reported deeper engagement levels using mobile apps and the virtual lab.

The health-promoting perks of wine have attracted the spotlight recently, leaving beer in the shadows. But scientists are discovering new ways in which the latter could be a more healthful beverage than once thought. It turns out that a compound from hops could protect brain cells from damage -- and potentially slow the development of disorders such as Alzheimer's and Parkinson's diseases.

Mothers who support their children's need for autonomy as the children grow tend to be viewed more positively by their children. The study included more than 2,000 mothers and their children. It measured maternal directiveness -- or the extent to which mothers controlled activities -- in play when children were 2 years old and then during a discussion about areas of disagreement when the children were in the fifth grade. Mothers' tendencies to display controlling behaviors predicted the extent to which the children viewed their mothers positively or negatively when the children were in fifth grade.

A novel radioguided surgery technique could quickly and effectively identify residual cancer cells during brain tumor surgery, with low radiation exposure for both patients and surgeons. The study reports that Y-90 DOTATOC, a beta-minus-emitting tracer, can effectively delineate the margins of meningiomas and high-grade gliomas.

Stress, traumatic events, and difficult life situations play a significant role in the development of many mental illnesses, such as depression, anxiety, addiction. However, not everyone exposed to such circumstances develops a psychological disorder as a result. A new approach to studying resilience focuses on the appraisal of stressful or threatening situations by the brain.

Stimulation of the hypothalamus completely reverses learning and memory deficits caused by brain lesions in rats, according to a first time discovery. The research has also served to study the mechanisms through which this recovery occurs, suggesting that the stimulation of the hypothalamus activates several regions of the brain, especially the memory systems, which offer compensatory effects.

The detection and imaging of protein-protein interactions in live cells just got a lot more colorful, thanks to a new technology. The new method converts biochemical processes into color changes that are easily visualized. This method is a new tool for cell biologists and neuroscientists to use to address questions ranging from fundamental mechanisms in cell biology, to the underlying causes of mental illness, to the discovery of novel therapeutics.

Prekindergarten students took part in a study assessing a new curriculum meant to promote social, emotional and academic skills. Researchers found that kids who had participated in the curriculum earned higher marks in academic performance measures and showed greater improvements in areas that predict future success than kids who had not.
