Parental physical discipline through childhood linked to behavior problems in teens
Two new studies explore how discipline changes during childhood and adolescence, and what family factors affect those changes. view more (2009-09-15)
Quality of life predicts cancer survival, U-M study finds
Head and neck cancer patients who reported lower physical quality of life were more likely to die from their disease, according to a new study from the University of Michigan Comprehensive Cancer Center. view more (2008-05-30)
Parachuting allows krill to eat and run
Antarctic researchers have recorded a novel behavior in krill that may help regulate greenhouse gases. Antarctic krill, one of the largest animal resources on Earth, parachute into the deeper layers of the ocean many times a night and sequester large amounts carbon in the process. view more (2006-02-07)
Good news for the medical marijuana movement: pot proliferates brain cells and boosts mood
Most drugs of abuse decrease the generation of new neurons in the brain, but the effects of marijuana on this process, called neurogenesis, had not been clear. view more (2005-10-14)
Scripps research scientists show protein accelerates breast cancer progression in animal models
These new findings could lead to a better understanding of the molecular pathogenesis of breast cancer and focus attention on PTN and its signaling pathway as possible targets for new cancer therapies. view more (2007-06-21)
UNC researchers find clue to stopping breast-cancer metastasis
If scientists knew exactly what a breast cancer cell needs to spread, then they could stop the most deadly part of the disease: metastasis. New research from the University of North Carolina at Chapel Hill School of Medicine takes a step in that direction. view more (2008-11-18)
Model identifies genes that induce normal skin cells to become abnormal
Northwestern University researchers have developed a novel, three-dimensional model that allows scientists to observe how interacting with the microenvironment of metastatic melanoma cells induces normal skin cells to become similar to aggressive cancer cells that migrate and spread throughout the body. view more (2005-11-15)
Coming undone: How stress unravels the brain's structure
The helpless behavior that is commonly linked to depression and post-traumatic stress disorder (PTSD) is preceded by stress-related losses of synapses-microscopic connections between brain cells-in the brain's hippocampal region, researchers at Yale School of Medicine report in the March 1 issue of Biological Psychiatry. view more (2009-03-04)
Scripps research scientists discover chemical triggers for aggression in mice
The work, reported in an advance, online issue of the journal Nature on December 6, 2007, furthers the broad and important goal of elucidating how the neurological system can detect and respond to specific cues in of a sea of potential triggers. view more (2007-12-07)
Pigs use brain not brawn in anger management
Pigs can use their brainpower to avoid the fighting that usually occurs when they are mixed together on farms, according to Dr Mike Mendl from the University of Bristol speaking at the BA Festival of Science [11.30hrs 11 September 2002]. The researchers have found that when competing for a hidden snack, pigs don’t simply rely on muscle to... view more... (2002-09-09)
Bullying in middle school may lead to increased substance abuse in high school
Over the past decade, parents, educators and policy makers have become increasingly concerned about verbal and physical harassment in schools and the subsequent effects of peer victimization on teens. view more (2005-12-30)
Pitt study shows linkage between teen girls' weight and sexual behavior
A University of Pittsburgh study sheds new light on the relationship between race, body weight and sexual behavior among adolescent girls. view more (2009-10-30)
Adolescents with high-risk sexual attitudes attract peers with similar attitudes
High-risk sexual behavior in adolescents appears to be influenced by the sexual attitudes of peers, and young people select friends whose attitudes about sex are consistent with their own attitudes. view more (2007-05-17)
2 nondrug treatments appear to reduce depression after heart surgery
Two non-pharmacological interventions-cognitive behavior therapy and supportive stress management-appear more effective than usual care for treating depression after coronary artery bypass surgery. view more (2009-04-07)
Reversing cancer cells to normal cells
In earlier work, Northwestern University scientist Mary J.C. Hendrix and colleagues discovered that aggressive melanoma cells (but not normal skin cells nor less aggressive melanoma cells) contain specific proteins similar to those found in embryonic stem cells. view more (2007-04-30)
Jefferson Scientists Find Protein May Play a Key Role in Development of Deadly Form of Pancreatic Cancer
A tumor-blocking protein previously implicated in prostate and breast cancer development may also be behind the most aggressive type of pancreatic cancer. Researchers at the Kimmel Cancer Center at Jefferson in Philadelphia have discovered that the protein, pp32 - which normally applies the brakes on a cancer-causing gene - is missing in an... view more...

Experiments could lead to new treatments for neuroblastoma
Neuroblastoma is one of the most devastating diagnoses a child can receive. The cancer's victims average 2 years old when the disease is detected, most often by a parent feeling a lump in a child's abdomen. By then, the disease has often reached an advanced stage, and advanced neuroblastoma kills more than 50 percent of the children in whom it... view more... (2008-08-18)
Why the swamp sparrow is hitting the high notes
Birdsongs are used extensively as models for animal signaling and human speech, offering a glimpse of how our own communicating abilities developed. view more (2009-01-12)
Targeting the protein AEG1 impairs human liver cancer growth in mice
Hepatocellular carcinoma (HCC) is a highly aggressive form of liver cancer and one of the 5 most common cancers worldwide. Devanand Sarkar and colleagues, at Virginia Commonwealth University School of Medicine, Richmond, have now identified a gene that is expressed at high levels in human HCC tumor samples and generates a protein important for HCC... view more...

Possible cause and potential treatment found for aggressive head and neck cancer
Researchers at the San Francisco VA Medical Center report that they have found a potential molecular cause for the aggressive growth and spread of human head and neck squamous cell carcinoma, a highly malignant form of cancer with a very high death rate. view more (2006-04-24)
