Illuminating mechanisms of repetitive thinking
2015-07-28
The ability to engage in mental time travel -- to delve back into past events or imagine future outcomes -- is a unique and central part of the human experience. And yet this very ability can have detrimental consequences for both physical and mental well-being when it becomes repetitive and uncontrolled.
A special series of articles in the July 2015 issue of Clinical Psychological Science (CPS) investigates this kind of repetitive thinking, exploring the core psychological processes that underlie maladaptive thought processes like worry and rumination. The series highlights ...
Race & institutional factors play an important role in pharmacogenomic trial participation
2015-07-28
TAMPA, Fla. - Cancer therapy has evolved from a "one-size-fits-all" type of treatment plan to a personalized approach based on a patient's type of cancer, the protein and genetic markers found in their tumors and their response to therapy. Important aspects of the personalized approach are pharmacogenomic studies that analyze associations between genetic variations and patient drug responses. Moffitt Cancer Center researchers have published a study in the Journal of the National Cancer Institute that analyzed the participation rate of patients in pharmacogenomic trials. ...
Study finds unexpected biases against teen girls' leadership
2015-07-28
CAMBRIDGE, Mass.-- Making Caring Common (MCC), a project of the Harvard Graduate School of Education, today released new research that suggests that many teen boys and teen girls--and some of their parents--have biases against teen girls as leaders. These biases could be powerful barriers to leadership for a generation of teen girls with historically high levels of education who are key to closing our nation's gender gap in leadership. The report also suggests that much can be done to prevent and reduce gender biases in children.
Titled "Leaning Out: Teen Girls and Gender ...
Ewing's sarcoma: A dangerous liaison
2015-07-28
Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich have elucidated at the molecular level how an otherwise innocuous inherited mutation that is quite common in European populations interacts with a spontaneous somatic mutation to promote the development of Ewing's sarcoma.
Ewing's sarcoma is an aggressive bone cancer that occurs primarily in children, adolescents and young adults. The tumor cells are characterized by a single spontaneous 'driver mutation', which results in formation of the oncogenic fusion gene EWSR1-FLI1. Its protein product EWSR1-FLI1, ...
'Carbon sink' detected underneath world's deserts
2015-07-28
WASHINGTON, D.C. - The world's deserts may be storing some of the climate-changing carbon dioxide emitted by human activities, a new study suggests. Massive aquifers underneath deserts could hold more carbon than all the plants on land, according to the new research.
Humans add carbon dioxide to the atmosphere through fossil fuel combustion and deforestation. About 40 percent of this carbon stays in the atmosphere and roughly 30 percent enters the ocean, according to the University Corporation for Atmospheric Research. Scientists thought the remaining carbon was taken ...

Facial motion capture - the same technology used to develop realistic computer graphics in video games and movies - has been used to identify differences between children with childhood apraxia of speech and those with other types of speech disorders, finds a new study by NYU's Steinhardt School of Culture, Education, and Human Development.
"In our study, we see evidence of a movement deficit in children with apraxia of speech, but more importantly, aspects of their speech movements look different from children with other speech disorders," said study author Maria Grigos, ...
Link between mood, pain in rheumatoid arthritis patients
2015-07-28
Depressive symptoms and mood in the moment may predict momentary pain among rheumatoid arthritis patients, according to Penn State researchers.
"The results of this study link momentary positive and negative mood with momentary pain in daily life," said Jennifer E. Graham-Engeland, associate professor of biobehavioral health. "That is, we found evidence consistent with a common, but largely untested, contention that mood in the moment is associated with fluctuation in pain and pain-related restrictions." The link was examined among individuals with rheumatoid arthritis, ...

Major European mouse study reveals the role of genes in disease
2015-07-28
Since mice share 90 percent of our genes they play an important role in understanding human genetics. The European Mouse Disease Clinic (EUMODIC) brought together scientists from across Europe to investigate the functions of 320 genes in mice. Over half of these genes had no previously known role, and the remaining genes were poorly understood.
In order to study gene function, the EUMODIC consortium produced mouse lines which each had a single gene removed. These mouse lines were then analyzed in mouse clinics, where each line was assessed by a series of tests and investigations, ...
Fatty acid increases performance of cellular powerhouse
2015-07-28
Mitochondria are essential to all higher forms of life. Every animal and plant depends on these small intracellular structures. Mitochondria have multiple tasks: Since they generate most of the cell's biochemical energy, they are referred to as the powerhouses of the cell. In addition, they are responsible for producing and breaking down amino acids and fats. They also regulate cellular death, called apoptosis.
As a result, the spectrum of diseases that are linked to mitochondrial defects is wide, ranging from severe muscular and nervous disorders to neurodegenerative ...
Identifying ever-growing disturbances leading to freak waves
2015-07-28
Physicists like to study unusual kinds of waves, like freak waves found in the sea. Such wave movements can be studied using models designed to describe the dynamics of disturbances. Theoretical physicists, based in France have focused on finding ways of best explaining how wave disturbance occurs under very specific initial conditions that are key to the genesis of these disturbances. They looked for solutions to this puzzle by resolving a type of equation, called the nonlinear Schrödinger equation. It is solved by applying a method designed for studying instabilities ...

Plant light sensors came from ancient algae
2015-07-28
DURHAM, N.C. -- The light-sensing molecules that tell plants whether to germinate, when to flower and which direction to grow were inherited millions of years ago from ancient algae, finds a new study from Duke University.
The findings are some of the strongest evidence yet refuting the prevailing idea that the ancestors of early plants got the red light sensors that helped them move from water to land by engulfing light-sensing bacteria, the researchers say.
The results appear online in Nature Communications.
