Mouse brain tumors mimic those in human genetic disorder

...with NF1 optic pathway gliomas, we may be treating kids whodon't need to be treated. Using this mouse model, we hope to continueto hone in on more accurate diagnostic, prognostic and treatmentapproaches."Bajenaru ML, Garbow JR, Perry A, Hernandez MR, Gutmann DH.

Innovative collaboration brings Arctic science into the classroom

...rnet communications. According to Holmes, "Getting kids excited about science is the most important thing. If they realize that science is an exciting process as opposed to a bunch of boring facts to memorize from textbooks, then this program will have been a tremendous success." In addition to his work ...

Scientists find a maturity gene in fly

"Our kids stay sweet and cute through about 12 years of life and then, suddenly, in response to steroid and thyroid hormones and their receptors [molecules that help hormones control genes], they begin this amazing transformation into smelly, hairy, sometimes ...

Sooner is better with cochlear implants, Stanford scientist shows

...nnection between lip movement and sound. The only kids who fully merged the visual and auditory effects of speech were those who had received implants before they were 30 months old, which indicates that the earlier the implant is done, the better the chances for fully integrated speech perception in the...

Animal models show that anabolic steroids flip the adolescent brain's switch for aggression

...ts abuse AASs each year. Not only do steroids set kids up for heavier use of steroids and other drugs later in life, but long-term users can suffer from mood swings, hallucinations and paranoia; liver damage; high blood pressure; as well as increased risk of heart disease, stroke and some types of cancer...

Zebra finches remember songs dad sang

...ts and, thus, be part of the mechanism that allows kids to learn any human language if they start early enough," Vicario says. "These findings are exciting," Kuhl says of the research reported in the paper. "They provide neurobiological evidence that helps explain human infants' acquisition of speech." ...

Molecular mechanism may explain how fevers spark seizures

It's one of those unavoidable facts of life -- kids get sick and have fevers. Usually, those elevated internal temperatures cause only temporary discomfort, but in some small children they spark convulsions called "febrile seizures." These convulsions are "scary and very upsetting to parents," said ...

Teens unaware of sexually transmitted diseases until they catch one, Carnegie Mellon study finds

... Journal of Adolescent Health. "For the most part kids learn about sexually transmitted diseases when they are getting diagnosed with them," said Julie Downs, lead author of the study and a member of the Department of Social and Decision Sciences at Carnegie Mellon. The results came from a survey of 30...

Genes affecting blood pressure change as children become adults

.... Snieder says. "The next step is following these kids for a long period of time to see whether the genetic effects stabilize or, after another three or four years, there is another large jump in new genetic effect," he says. Despite conventional thinking, this scientist who focuses on genetics, was not ...

With cochlear implants, earlier use leads to better speech

...unds are magnified more with cochlear implants, so kids can hear 's' sounds and 'ed' endings better. So they tend to catch on to plurals and verb tenses faster." While studies like this and others favor early implantation, the decision for or against cochlear implantation is frequently put off, Nicholas...

A natural chemical found in strawberries boosts memory in healthy mice

...ildren to eat their fruit and vegetables. But once kids are beyond mom's watchful eye, the hated greens often go the way of Barbie dolls and power rangers. Now, there's another reason to reach for colorful fruits past adolescence. Fisetin, a naturally occurring flavonoid commonly found in strawberries an...

Artificial cornea offers better results for infants, some blind patients

...ent operation. But with the plastic implant, these kids are looking great. "The timing is crucial, because if a child hasn't seen out of an eye for a few years, and then suddenly vision in the eye is fixed, the brain doesn't know what to do with that information," Gearinger added. "If the brain has bee...

Studies look at how genes affect antipsychotic drug response

...ng patients. "We are trying to determine if some kids are at a greater risk than others for these problems by analyzing genetic markers," Bishop said. Bishop said if children are to receive long-term drug therapy, clinicians need to make sure they are appropriately monitored and treated as safely as p...

Fish can determine their social rank by observation alone, study finds

...easoning," Fernald explained. "It's something that kids generally figure out by age 4 or 5--Mary is taller than Fred, Fred is taller than Pete, therefore Mary is taller than Pete. It's been demonstrated in primates, rats and some bird species, but how and why it evolved in animals is a matter of debate." ...

With sleep and GI function operating optimally, many of the residual behaviors we see in children with autism decrease sign...

Eavesdropping comes naturally to young song sparrows

...their parents or a sibling, Beecher said. "Do kids learn from parents talking to them or from other people talking and interacting" We don’t know. We do know that children’s comprehension is much farther ahead than their language production ability, certainly in the first couple of years of life. T...

Prenatal Stress Keeps Infants, Toddlers up at Night, Study Says

However, more research is needed to monitor this signaling pathway more closely, watching for biological hints as to why sleep and behavioral disturbances so often crop up together...
