Depressed people have trouble learning 'good things in life'

COLUMBUS, Ohio – While depression is often linked to negative thoughts and emotions, a new study suggests the real problem may be a failure to appreciate positive experiences.

Researchers at Ohio State University found that depressed and non-depressed people were about equal in their ability to learn negative information that was presented to them.

But depressed people weren't nearly as successful at learning positive information as were their non-depressed counterparts.

Spinal taps carry higher risks for infants and elderly, study shows

WINSTON-SALEM, N.C. – An X-ray-guided spinal tap procedure fails more than half of the time in young infants and should be used sparingly, if at all, for those patients, according to a new study done by researchers at Wake Forest University School of Medicine.

Regular exercise reduces depressive symptoms, improves self-esteem in overweight children

Augusta, Ga. - Less than an hour of daily exercise reduces depressive symptoms and improves self esteem in overweight children, Medical College of Georgia researchers say.

The study included 207 overweight, typically sedentary children ages 7-11 randomly assigned to either continue their sedentary lifestyle or exercise for 20 or 40 minutes every day after school for an average of 13 weeks. The 40-minute group sustained the most psychological benefit, according to research published online in the Journal of Pediatric Psychology.

Study finds biological clue in brain tumor development

Scientists at The University of Nottingham have uncovered a vital new biological clue that could lead to more effective treatments for a children's brain tumour that currently kills more than 60 per cent of young sufferers.

Fruit flies' response to wind offers new window to neural circuits

Try this at home: If fruit flies are buzzing around your kitchen, switch on your hairdryer and aim it at the flies. A gentle stream of air will stop them in their tracks, putting them in prime position for swatting.

The reaction of fruit flies to wind was something that had intrigued biologist David J. Anderson for some time. When the flies sensed the wind, they went into a defensive, hunkering-down position until the feel of the wind ceased, then resumed flying around.

Mechanism of Alzheimer's suggests combination therapy needed

Researchers at the University of Illinois at Chicago College of Medicine have discovered a mode of action for mysterious but diagnostic protein snarls found in the brains of Alzheimer's patients that suggests a one-two punch of therapy may be needed to combat the neurodegenerative disease.

Drug being used to improve cognition affects dopamine, suggesting potential for abuse

Preliminary research in healthy men suggests that the narcolepsy drug modafinil, increasingly being used to enhance cognitive abilities, affects the activity of dopamine in the brain in a way that may create the potential for abuse and dependence, according to a study in the March 18 issue of JAMA.

Link between religious coping and aggressive treatment in terminally ill cancer patients

BOSTON ––– In a new study of terminally ill cancer patients, researchers at Dana-Farber Cancer Institute found that those who draw on religion to cope with their illness are more likely to receive intensive, life-prolonging medical care as death approaches –– treatment that often entails a lower quality of life in patients' final days.

Contrary to widely held beliefs, romance can last in long-term relationships, say researchers

WASHINGTON – Romance does not have to fizzle out in long-term relationships and progress into a companionship/friendship-type love, a new study has found. Romantic love can last a lifetime and lead to happier, healthier relationships.

Brain abnormality found in boys with attention deficit hyperactivity disorder

Researchers trying to uncover the mechanisms that cause attention deficit hyperactivity disorder and conduct disorder have found an abnormality in the brains of adolescent boys suffering from the conditions, but not where they expected to find it.

Boys with either or both of these disorders exhibited a different pattern of brain activity than normally developing boys when they played a simple game that sometimes gave them a monetary reward for correct answers, according to a new study by a University of Washington research team.

Study gives more proof that intelligence is largely inherited

They say a picture tells a thousand stories, but can it also tell how smart you are? Actually, say UCLA researchers, it can.

Financial security, more than money alone, may be key to happiness, Princeton study says

A study of the mental state of the modern American woman by a Princeton University psychologist has found a powerful link between concerns over financial security and satisfaction with one's life.

New tumor markers determine therapy intensity

Characteristic changes in the DNA of medulloblastoma, the most frequent malignant brain tumor in childhood, indicate precisely how aggressively the tumor will continue to spread and what the chances of disease relapse are. Researchers at the Center for Pediatric and Adolescent Medicine at the Heidelberg University Hospital and the German Cancer Research Center have discovered this correlation. With this new set of tumor markers, the intensity of treatment can be adjusted individually and the potentially damaging effects reduced.

Love at first aria - the psychology of opera?

A passion for opera starts with an initial explosive, emotional experience. This is followed by a gradual learning process over a number of years during which fans discover how to truly appreciate it fully. Through his observation of middle class opera fans who stand on the upper floors of the Colón Opera House in Buenos Aires, Claudio Benzecry from the University of Connecticut in the USA sheds light on what it takes to develop a true passion for opera. His findings are published online in Springer's journal Qualitative Sociology.

Emotions can help predict future eating disorders

A Ph.D. thesis at the University of the Basque Country has analyzed the role played by a number of emotional variables, such as the way in which negative emotions are controlled or attitudes to emotional expression, and to use these variables as tools to predict the possibility of suffering an eating disorder.
