After a decade of decline, the suicide rate for girls ages 10 to 14 spiked by 76 percent in 2004, and their method of choice changed from firearms to suffocation and hanging, federal officials said Thursday. The rate among older boys and girls also increased substantially, driving the overall suicide rate among 10- to 24-year- olds to an 8 percent increase in 2004, the largest jump in 15 years, according to the Centers for Disease Control and Prevention's latest Morbidity and Mortality Weekly Report. The rate had declined by 28 percent between 1990 and 2003 before the jump in 2004.

Research News: Toddlers Outsmart Chimps in Some Tasks, Not All
The News:
NPR's Morning Edition, September 7, 2007 · What makes humans different from our closest primate relatives? Scientists have grappled with the question for centuries – even more so since the discovery, in the late 1980s, that humans and apes share pretty much the same genetic code. Just think about it, says anthropologist Brian Hare: The two species share practically the same DNA, and yet live such different lives.

Dinosaur-Killing Asteroid Traced to Breakup Event
NPR All Things Considered, September 5, 2007
The reason humans rule the Earth could be due to a huge collision that took place 160 million years ago. Somewhere between Jupiter and Mars, two asteroids smashed into each other. The debris hurtled into space, and eventually a big piece hit the Earth. This was the asteroid that wiped out the dinosaurs and gave mammals a chance.

Research news: Microchip patterning technology created
The News:
Microchip patterning technology created
PRINCETON, N.J., Sept. 5 (UPI) -- U.S. engineers have developed a low-cost technology that patterns microchips.
Princeton University engineers said the "fracture-induced structuring" results in the self-formation of periodic lines, or gratings, separated by as few as 60 nanometers. Such features, researchers said, have many uses in optical, biological and electronic devices, including the alignment of liquid crystals in displays.
The process begins by the painting of a thin polymer film onto a rigid plate, such as a silicon wafer. Then, a second plate is placed on top, creating a polymer sandwich that is heated to ensure adhesion. Finally, the two plates are pried apart.
As the film fractures, it automatically breaks into two complementary sets of nanoscale gratings, one on each plate.

Study Finds Some Children Being Misdiagnosed with Asthma
Friday, August 31, 2007
Fox News
It's believed that six million American children suffer from asthma. However, new research shows that some children who have been diagnosed with the condition may actually suffer from a vocal cord affliction. Doctors at Columbus Children's Hospital believe that at least some children diagnosed with asthma may actually suffer from vocal cord dysfunction (VCD), a sudden, abnormal narrowing of the vocal cords during inhalation causing obstruction of the airflow, and characterized by a noise that can mimic the sound of wheezing.

Ovary Removal May Cause Dementia Risk
By MALCOLM RITTER, AP
NEW YORK - Women who have their ovaries removed before menopause run a heightened risk of developing dementia or other mental problems later in life - unless they take estrogen until age 50, a new study suggests. Experts said the research needs to be confirmed by further study, but the findings suggest another issue for premenopausal women and their doctors to discuss as they consider ovary removal.

Male readers respond to female teachers
EDMONTON, Alberta, Aug. 24 (UPI) -- Boys struggling with reading respond better to female teachers, a study by researchers at the University of Alberta found.
The study examined 175 third- and fourth-grade boys who were identified by their teachers as struggling readers. The boys participated in a 10-week reading intervention to determine the effect of the reading teachers' gender on boys' reading performance, self-perception as readers and view of reading as a masculine, feminine or gender-neutral activity.

Make switch to medication a last resortBy Jane E. BrodyThe New York TimesArticle Last Updated: 08/26/2007 03:13:02 PM MDT
Last December, a routine non-fasting blood test revealed that my total cholesterol level, which had long wavered between 190 and 205 milligrams per deciliter of blood serum, was now 222 and flagged as "high" by the laboratory's computer. A heart-healthy reading should be under 200. Americans tend to turn far too quickly to drugs to solve their health problems. ... Drugs should be the last resort, if there are reasonable measures people can take first to control a problem. And there are dozens of such measures that, individually or together, can help to lower high LDL cholesterol.
