Children Can Outgrow Chronic Daily Headache Posted: 18 Jul 2009 02:00 AM PDT Most children who suffer from chronic daily headache may outgrow the disabling condition, according to new research. Nearly 1.5 percent of middle school children are affected by chronic daily headache, which includes chronic migraines and tension-type headaches.

Delinquent Behavior Among Boys 'Contagious,' Study Finds Posted: 17 Jul 2009 08:00 PM PDT Impulsive boys with inadequate supervision, poor families and deviant friends are more likely to commit criminal acts that land them in juvenile court, according to a new study. The most surprising finding from the 20-year study was how help provided by the juvenile justice system substantially increased the risk of the boys engaging in criminal activities during early adulthood.

Obesity Raises Risk Of Complications In Pregnancy, Study Shows Posted: 17 Jul 2009 08:00 PM PDT Expectant mothers who are obese are much more likely to suffer from minor complications such as heart burn and chest infections during pregnancy, a study suggests. Research found that obese mothers-to-be were nearly 10 times more likely to suffer from chest infections, and more than twice as likely to suffer from headaches and heartburn, compared with pregnant women of a healthy weight.

Water Webs: Connecting Spiders, Residents In The Southwest Posted: 17 Jul 2009 08:00 PM PDT If you are a cricket and it is a dry season on the San Pedro River in Arizona, on your nighttime ramblings to eat leaves, you are more likely to be ambushed by thirsty wolf spiders. A potential horror story for any cricket. However, it is also a tale of water limitation that looks beyond how most ecosystem studies are considered.

Biomarker Of Breathing Control Abnormality Associated With Hypertension And Stroke Posted: 17 Jul 2009 08:00 PM PDT Scientists have identified a distinct ECG-derived spectrographic phenotype, designated as narrow-band elevated low frequency coupling (e-LFCNB), that is associated with prevalent hypertension, stroke, greater severity of sleep disordered breathing and sleep fragmentation in patients suffering from obstructive sleep apnea.

Researchers Help Set Security Standards For The Internet Posted: 17 Jul 2009 08:00 PM PDT Secure Internet activity requires being able to prove who you are, and experts agree that the traditional approach of passwords is not always effective. PKI and public key cryptography solve these problems, and a new system is now in the pipeline with the Internet Engineering Task Force to become the universal way to easily implement PKI-enhanced computing security.

Foster Care May Boost Brain Activity Of Institutionalized Children Posted: 17 Jul 2009 08:00 PM PDT A longitudinal study of 200 Romanian children between the ages of 5 months and 42 months shows the effects of institutionalization on brain and behavioral development. Compared with children who grew up in families, children raised in institutions showed a pattern of reduced brain activity when they looked at pictures of a caregiver's face that alternated with pictures of a stranger's face. Children who were placed in high-quality foster care showed the beginnings of normalized brain activity when processing faces.

Why Neural Stem Cells Divide And Differentiate Posted: 17 Jul 2009 05:00 PM PDT Neural stem cells represent the cellular backup of our brain. These cells are capable of self-renewal to form new stem cells or differentiate into neurons, astrocytes or oligodendrocytes. The receptors of the Notch family play a significant role in this process. So far, only stimulating extracellular ligands of Notch receptors had been described. Biochemists now describe a long time assumed but not yet identified soluble Notch inhibitor.

Human-computer Interaction: Beyond – Way Beyond – WIMP Interfaces Posted: 17 Jul 2009 05:00 PM PDT Human-computer interaction is undergoing a revolution, entering a multimodal era that goes beyond, way beyond, the WIMP (Windows-Icons-Menus-Pointers) paradigm. Now researchers have developed a platform to speed up that revolution.

In Adolescence, Girls React Differently Than Boys To Peers' Judgments Posted: 17 Jul 2009 05:00 PM PDT A new study shows what happens in the brains of preteens and teens at a time of significant change in social behavior. Using brain scan technology, researchers found that in older girls (as compared to younger girls), brain regions associated with social rewards and motivation responded differently when they thought about being judged by their peers. These differences were not evident between younger and older boys.

Genetic Source Of Muscular Dystrophy Neutralized: Possible Cure? Posted: 17 Jul 2009 02:00 PM PDT Researchers have found a way to block the genetic flaw at the heart of a common form of muscular dystrophy.

Infants Should Be Screened For Hip Trouble Posted: 17 Jul 2009 02:00 PM PDT Developmental hip dysplasia is the most common congenital defect in newborns. The condition occurs when a hip joint is shallow, unstable or when the joint is dislocated. Infants with the condition are often at risk of developing arthritis of the hip as a young adult. A new study finds that screening all infants for hip dysplasia can significantly decrease their chance of developing early arthritis.

Ocean Current Shutdown May Be Gradual, Not Sudden Posted: 17 Jul 2009 02:00 PM PDT The findings of a major new study are consistent with gradual changes of current systems in the North Atlantic Ocean, rather than a more sudden shutdown that could lead to rapid climate changes in Europe and elsewhere.

Stress And Depression Worsen Childhood Asthma, Researchers Show Posted: 17 Jul 2009 02:00 PM PDT Young people with asthma have nearly twice the incidence of depression compared to their peers without asthma, and studies have shown that depression is associated with increased asthma symptoms and, in some cases, death.
