Earthquakes have aftershocks — not just the geological kind but the mental kind as well. Just like veterans of war, earthquake survivors can experience post-traumatic stress disorder, depression and anxiety.

In 1988, a massive earthquake in Armenia killed 17,000 people and destroyed nearly half the town of Gumri. Now, in the first multigenerational study of its kind, UCLA researchers studying survivors of that catastrophe have discovered that vulnerability to PTSD, anxiety and depression runs in families.

HOUSTON - Amy Heimberger, M.D., associate professor of neurosurgery at The University of Texas M. D. Anderson Cancer Center has received a Presidential Early Career Award for Scientists and Engineers (PECASE), in recognition for her research on the central nervous system's immune biology, tumor evasion of immune detection and immunotherapeutic approaches for patients with malignant gliomas.

ALEXANDRIA, VA---December 19, 2008--- New research out of the University of Pittsburgh indicates that patients' perceptions of their own health and balance have an impact on how much they walk. The study was originally published in Physical Therapy (December 2008), the scientific journal of the American Physical Therapy Association (APTA).

ITHACA, N.Y. – A prototype of a therapeutic ultrasound device, developed by a Cornell graduate student, fits in the palm of a hand, is battery-powered and packs enough punch to stabilize a gunshot wound or deliver drugs to brain cancer patients. It is wired to a ceramic probe, called a transducer, and it creates sound waves so strong they instantly cause water to bubble, spray and turn into steam.

ROCHESTER, Minn. -- Mayo Clinic research shows adults with asthma are at increased risk of serious pneumococcal disease caused by Streptococcus pneumoniae, the most common bacteria causing middle ear infections and community acquired pneumonia. It also causes blood stream infections and brain infections. According to the Centers for Disease Control, pneumococcal infection is one of the leading causes of death from a vaccine-preventable disease. The researchers recommend including asthma as an indication for pneumococcal vaccination in adults.

ITHACA, N.Y. – To many people, bird song can herald the coming of spring, reveal what kind of bird is perched nearby or be merely an unwelcome early morning intrusion. But to Sandra Vehrencamp, Cornell professor of neurobiology and behavior, bird song is a code from which to glean avian behavior insight.

(Toronto, Friday, December 19, 2008) – For the first time in the world, transplant surgeons at Toronto General Hospital, University Health Network used a new technique to repair an injured donor lung that was unsuitable for transplant, and then successfully transplanted it into a patient. The use of this technique could significantly expand the lung donor organ pool and improve outcomes after transplantation.

INDIANAPOLIS – A national alcohol research group is concerned that the media's misinterpretation of a recent British research study could encourage pregnant women to be more at ease with temperate alcohol consumption.

Some media reports erroneously stated that the study by The University College London researchers revealed that light drinking by pregnant women could be beneficial to their babies. Other articles said light drinking during pregnancy would not affect the behavior or mental acuity of babies born to drinking mothers.

The old adage that we can only learn how to do something by trying it ourselves may have to be revised in the light of recent discoveries in neuroscience. It turns out that humans, primates, some birds, and possibly other higher animals have mirror neurons that fire in the same pattern whether performing or just observing a task.

Baltimore, MD -- A study published today in the December issue of the European medical journal Anticancer Research demonstrates that an ingredient used in a common cough suppressant may be useful in treating advanced prostate cancer. Researchers found that noscapine, which has been used in cough medication for nearly 50 years, reduced tumor growth in mice by 60% and limited the spread of tumors by 65% without causing harmful side effects.

WASHINGTON – Nearly 50 years after one of the most controversial behavioral experiments in history, a social psychologist has found that people are still just as willing to administer what they believe are painful electric shocks to others when urged on by an authority figure.

Jerry M. Burger, PhD, replicated one of the famous obedience experiments of the late Stanley Milgram, PhD, and found that compliance rates in the replication were only slightly lower than those found by Milgram. And, like Milgram, he found no difference in the rates of obedience between men and women.

HOUSTON - (Dec. 18, 2008)- Testing patient's blood for two proteins or biomarkers that occur when inflammation is present could help doctors identify which patients are more likely to have a stroke, said researchers at Baylor College of Medicine in Houston in a report that appears online in the journal Stroke.

Tampa, FL (Dec. 18, 2008) -- MRI scans that detect shrinkage in specific regions of the mid-brain attacked by Alzheimer's disease accurately diagnose the neurodegenerative disease, even before symptoms interfere with daily function, a study by the Florida Alzheimer's Disease Research Center (ADRC) in Miami and Tampa found.

A greater commitment by science faculty to focus on science education could drive education reform at universities and K-12 schools, according to a new report by a team of five researchers from the California State University (CSU) system and one from Purdue University.

Appearing in today's issue of the journal Science, the report evaluates the role that science professors who specialize in science education play in improving how the sciences are taught.

Learning how leukemia takes over privileged "niches" within the bone marrow is helping researchers develop treatment strategies that could protect healthy blood-forming stem cells and improve the outcomes of bone marrow transplantation for leukemia and other types of cancer.
