College Park, MD – A University of Maryland study projects that Washington, D.C. city and federal property could suffer billions of dollars in damage if sea level rise from global warming increases over the next century. Potential for significant damage will be even greater in the event of extreme weather like Hurricane Sandy

The study by Civil and Environmental Engineering Professor Bilal Ayyub, Haralamb Braileanu and Naeem Qureshi, of the Clark School of Engineering’s Center for Technology and Systems Management, looks at possible long term effects of projected sea level rise on Washington, D.C. real-estate property and government infrastructure. They conclude that over the next 100 years, continuing sea level rise could cause damages of more than $24.6 billion to Washington’s commercial property, museums, and government agencies. (more…)

Common Parasite May Trigger Suicide Attempts

EAST LANSING, Mich. — A parasite thought to be harmless and found in many people may actually be causing subtle changes in the brain, leading to suicide attempts.

New research appearing in the August issue of The Journal of Clinical Psychiatry adds to the growing work linking an infection caused by the Toxoplasma gondii parasite to suicide attempts. Michigan State University’s Lena Brundin was one of the lead researchers on the team.

About 10-20 percent of people in the United States have Toxoplasma gondii, or T. gondii, in their bodies, but in most it was thought to lie dormant, said Brundin, an associate professor of experimental psychiatry in MSU’s College of Human Medicine. In fact, it appears the parasite can cause inflammation over time, which produces harmful metabolites that can damage brain cells. (more…)

For Some Medical Residents, Empathy Declines With Long-Call

*In a newly published study, researchers found the majority of medical residents surveyed experienced a decline in empathy over the course of the oft-used “long-call” shift.*

Fatigue and sleep deprivation are undisputed job descriptors for medical residents, but results from a new study indicate the common “long-call” shift may have adverse effects not only for residents, but also their patients.

University of Arizona alumna Stacey Passalacqua, now a visiting assistant professor at James Madison University’s School of Communication, surveyed nearly 100 medical residents at several different hospitals. (more…)

Gene Research Sheds Light on Timing of Menopause

An international team of researchers has discovered 13 new regions of the genome associated with the timing of menopause.

These genes shed light on the biological pathways involved in reproductive lifespan and will provide insights into conditions connected to menopause, such as breast cancer and heart disease.

Menopause is a major hormonal change that affects most women when they are in their early 50s. The timing of menopause can have a huge impact on fertility, as well as influencing the risk of a range of common diseases such as breast cancer. It has been known for some time that genetic factors influenced the onset of menopause, however until recently very few genes had been identified.

In the new study, published in the journal Nature Genetics on 22 January 2012, Dr Anna Murray, University of Exeter, Peninsula College of Medicine and Dentistry (PCMD) Dr John Perry, PCMD and WTCHG, University of Oxford, and dozens of international collaborators, examined the genomes of over 50,000 women. They identified 13 novel gene regions associated with menopause onset, and confirmed four previously identified. Most of the 17 regions include genes related to DNA damage/repair or the immune system, whilst others are linked to hormonal regulation. (more…)

UCLA Scientists Design Experimental Treatment for Iron-Overload Diseases

Iron overload is a common condition affecting millions of people worldwide. Excess iron in the body is toxic, and deposits can cause damage to the liver, heart and other organs. Current treatments, researchers say, are not ideal and have significant side effects.

Iron in the body is regulated by a hormone called hepcidin, and a deficiency in this hormone can cause the iron overload seen in genetic disorders like hereditary hemochromatosis and Cooley’s anemia. (more…)

ANN ARBOR, Mich.— DNA, that marvelous, twisty molecule of life, has an alter ego, research at the University of Michigan and the University of California, Irvine reveals.

On rare occasions, its building blocks “rock and roll,” deforming the familiar double helix into a different shape. (more…)
