Misregulated genes may have big autism role

A genetic pathway involving proteins in the endosomes of cells appears to be misregulated in the brains of children with autism, according to a newly published statistical analysis in the journal Molecular Psychiatry. Previously the genes were shown to cause rare forms of the disease but the new study suggests they have a wider role.

PROVIDENCE, R.I. [Brown University] — A new study finds that two genes individually associated with rare autism-related disorders are also jointly linked to more general forms of autism. The finding suggests a new genetic pathway to investigate in general autism research. (more…)

High-speed rail study finds that remote cities benefit from connection to global hubs

Bullet trains fuel real-estate booms, improve quality of life and create other unintended consequences by sharply reducing commute times from smaller cities to large megacities, economists from UCLA and China’s Tsinghua University observed in a new study in China. A similar dynamic, they said, could play out as California builds its own high-speed rail system.

Because high-speed rail effectively brings cities closer together by reducing travel times, it allows people to enjoy many of the benefits of big cities while living in “second-tier” cities far from the pollution and congestion. By making second-tier cities attractive to those who would otherwise flock to global hubs, bullet trains could act as a safety valve for crowded megacities in the developing world and ease the effects of overpopulation, the study authors report.

‘Cool’ Kids In Middle School Bully More, UCLA Psychologists Report

Study of seventh and eighth graders finds no difference between boys, girls

Bullying, whether it’s physical aggression or spreading rumors, boosts the social status and popularity of middle school students, according to a new UCLA psychology study that has implications for programs aimed at combatting school bullying. In addition, students already considered popular engage in these forms of bullying, the researchers found.

The psychologists studied 1,895 ethnically diverse students from 99 classes at 11 Los Angeles middle schools. They conducted surveys at three points: during the spring of seventh grade, the fall of eighth grade and the spring of eighth grade. Each time, students were asked to name the students who were considered the “coolest,” the students who “start fights or push other kids around” and the ones who “spread nasty rumors about other kids.” (more…)

Transforming America by Redirecting Wasted Health Care Dollars

Eliminating excessive spending could mean windfall for U.S., study suggests

The respected national Institute of Medicine estimates that $750 billion is lost each year to wasteful or excessive health care spending. This sum includes excess administrative costs, inflated prices, unnecessary services and fraud — dollars that add no value to health and well-being.

If those wasteful costs could be corralled without sacrificing health care quality, how might that money be better spent? (more…)

State-Mandated Planning, Higher Resident Wealth Linked to More Sustainable City Transportation

COLUMBUS, Ohio – Transportation practices tend to be more environmentally friendly in wealthier metropolitan areas located within states that mandate comprehensive planning, new research suggests.

The study involved an examination of 225 U.S. metropolitan areas between 1980 and 2008 to gauge how sustainable their transportation practices were and determine what kinds of socioeconomic factors appeared to influence those practices. (more…)

CU Mathematicians Show How Shallow Waves May Help Explain Tsunami Power

While wave watching is a favorite pastime of beachgoers, few notice what is happening in the shallowest water. A closer look by two University of Colorado Boulder applied mathematicians has led to the discovery of interacting X- and Y-shaped ocean waves that may help explain why some tsunamis are able to wreak so much havoc.

Professor Mark Ablowitz and doctoral student Douglas Baldwin repeatedly observed such wave interactions in ankle-deep water at both Nuevo Vallarta, Mexico, and Venice Beach, Calif., in the Pacific Ocean — interactions that were thought to be very rare but which actually happen every day near low tide. There they saw single, straight waves interacting with each other to form X- and Y-shaped waves as well as more complex wave structures, all predicted by mathematical equations, said Ablowitz.

NASA’s Spitzer Finds First Objects Burned Furiously

PASADENA, Calif. — The faint, lumpy glow given off by the very first objects in the universe may have been detected with the best precision yet, using NASA’s Spitzer Space Telescope. These faint objects might be wildly massive stars or voracious black holes. They are too far away to be seen individually, but Spitzer has captured new, convincing evidence of what appears to be the collective pattern of their infrared light.

The observations help confirm the first objects were numerous in quantity and furiously burned cosmic fuel.

“These objects would have been tremendously bright,” said Alexander “Sasha” Kashlinsky of NASA’s Goddard Space Flight Center in Greenbelt, Md., lead author of a new paper appearing in The Astrophysical Journal. “We can’t yet directly rule out mysterious sources for this light that could be coming from our nearby universe, but it is now becoming increasingly likely that we are catching a glimpse of an ancient epoch. Spitzer is laying down a roadmap for NASA’s upcoming James Webb Telescope, which will tell us exactly what and where these first objects were.” (more…)
