Salmon spawn baby trout in experiment
WASHINGTON (AP) — Papa salmon plus mama salmon equals ... baby trout?
Japanese researchers put a new spin on surrogate parenting as they engineered one fish species to produce another, in a quest to preserve endangered fish.
Idaho scientists begin the next big step next month, trying to produce a type of salmon highly endangered in that state — the sockeye — this time using more plentiful trout as surrogate parents.
The new method is "one of the best things that has happened in a long time in bringing something new into conservation biology," said University of Idaho zoology professor Joseph Cloud, who is leading the U.S. government-funded sockeye project.
The Tokyo University inventors dubbed their method "surrogate broodstocking." They injected newly hatched but sterile Asian masu salmon with sperm-growing cells from rainbow trout — and watched the salmon grow up to produce trout.

Physicists get two atoms to communicate
ANN ARBOR, Mich., Sept. 11 (UPI) -- U.S. physicists have, for the first time, coaxed two atoms to communicate with a type of quantum intuition that Albert Einstein once called "spooky."
The University of Michigan researchers said their accomplishment marks an advance toward super-fast quantum computing and might also be the start of a quantum internet.
The scientists used light to establish what's called "entanglement" between two atoms, which were trapped 1 meter apart in separate enclosures. They described entangling as similar to controlling the outcome of one coin flip with the outcome of a separate coin flip.

Research news: Reports rise of death, harm from medicine
The News:
Reports rise of death, harm from medicine
Incidents more than doubled from 1998 to '05, which may fuel calls for better federal regulation.
By Bruce Japsen Chicago Tribune
Article Last Updated: 09/10/2007 11:26:04 PM MDT
Chicago - The number of serious injuries and deaths reported to the U.S. Food and Drug Administration from drugs more than doubled between 1998 and 2005, according to a report in Monday's Archives of Internal Medicine published by the American Medical Association.
The report is expected to add momentum to reform the federal government's monitoring of prescription drugs.
The study said the dramatic rise in "adverse events" reported to the FDA point out myriad problems with the monitoring of drugs before approval and after they are on the market.
Incidents resulting in death or serious injuries such as birth defects, disability and hospitalization were examined.
The report suggested that the FDA and the health care system, including doctors, hospitals and other caregivers, are lacking in their ability to manage medications.

Research news: Liberal, conservative brains work differently
The News:
Liberal, conservative brains work differently
By the Los Angeles Times
Article Last Updated: 09/09/2007 11:36:48 PM MDT
Exploring the neurobiology of politics, scientists have found that liberals tolerate ambiguity and conflict better than conservatives because of how their brains work.
Scientists at New York University and the University of California at Los Angeles report today in the journal Nature Neuroscience that political orientation is related to differences in how the brain processes information.
Previous psychological studies have found that conservatives tend to be more structured and persistent in their judgments, whereas liberals are more open to new experiences. The latest study found those traits are not confined to political situations but also influence daily decisions.
Participants' politics ranged from "very liberal" to "very conservative." Scientists instructed them to tap a keyboard when an M appeared on a computer monitor and to refrain from tapping when they saw a W. M appeared four times as frequently as W.

Spike in suicide rate spurs worry
Real numbers remain small, but climb reverses a downward trend
By Thomas H. Maugh II and Jia-Rui Chong, Los Angeles Times
Article Last Updated: 09/06/2007 11:16:22 PM MDT
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.
