Angelina Jolie Effect: Breast Cancer Awareness vs. Knowledge

COLLEGE PARK, Md. – Angelina Jolie heightened awareness about breast cancer when she announced in a New York Times op-ed that she had undergone a preventive double mastectomy. But a new study led by researchers in the University of Maryland School of Public Health and the Johns Hopkins School of Public Health reveals that widespread awareness of Jolie’s story did not translate into increased understanding of breast cancer risk.

The survey of more than 2,500 Americans found that three out of four were aware of Jolie’s story, but fewer than 10 percent of those could correctly answer questions about the BRCA gene mutation that Jolie carries and the typical person’s risk of developing breast cancer. Though very rare, women with harmful mutations in either of two genes, BRCA1 and BRCA2, have a risk of breast cancer that is about five times the normal risk, and a risk of ovarian cancer that is about ten to thirty times normal. The study is published on December 19, 2013 in Genetics in Medicine. (more…)

Evolution, Civil War History Entwine in Fossil Find

COLLEGE PARK, Md. – A fossil leaf fragment collected decades ago on a Virginia canal bank has been identified by a University of Maryland doctoral student as one of North America’s oldest flowering plants, a 115- to 125-million-year-old species new to science. The fossil find, an ancient relative of today’s bleeding hearts, poses a new puzzle in the study of plant evolution: did Earth’s dominant group of flowering plants evolve along with its distinctive pollen? Or did pollen come later?

The find also unearths a forgotten chapter in Civil War history reminiscent of the film “Twelve Years a Slave,” but with a twist. In 1864, Union Army troops forced a group of freed slaves into involuntary labor, digging a canal along the James River at Dutch Gap, Va. The captive men’s shovels exposed the oldest flowering plant fossil beds in North America, where the new plant species was ultimately found. (more…)

The Era of Neutrino Astronomy has Begun

COLLEGE PARK, Md. – Astrophysicists using a telescope embedded in Antarctic ice have succeeded in a quest to detect and record the mysterious phenomena known as cosmic neutrinos – nearly massless particles that stream to Earth at the speed of light from outside our solar system, striking the surface in a burst of energy that can be as powerful as a baseball pitcher’s fastball. Next, they hope to build on the early success of the IceCube Neutrino Observatory to detect the source of these high-energy particles, said Physics Professor Gregory Sullivan, who led the University of Maryland’s 12-person team of contributors to the IceCube Collaboration.

“The era of neutrino astronomy has begun,” Sullivan said as the IceCube Collaboration announced the observation of 28 very high-energy particle events that constitute the first solid evidence for astrophysical neutrinos from cosmic sources.  (more…)

UA Sociologist Studies Resiliency in Communities Devastated by Hurricane Sandy

Sociology professor Brian Mayer’s research is part of an $8 million Health and Human Services project focused on long-term recovery.

The disastrous flooding Hurricane Sandy brought to Maryland’s coastal communities left a long road to recovery.

An expert in how communities rebound from large-scale disasters, University of Arizona sociology professor Brian Mayer is working to model the relationship between the resiliency of communities and individuals. (more…)

Researchers Find Genetic Diversity Key to Survival of Honey Bee Colonies

When it comes to honey bees, more mates is better. A new study from North Carolina State University, the University of Maryland and the U.S. Department of Agriculture (USDA) shows that genetic diversity is key to survival in honey bee colonies – a colony is less likely to survive if its queen has had a limited number of mates.

“We wanted to determine whether a colony’s genetic diversity has an impact on its survival, and what that impact may be,” says Dr. David Tarpy, an associate professor of entomology at North Carolina State University and lead author of a paper describing the study. “We knew genetic diversity affected survival under controlled conditions, but wanted to see if it held true in the real world. And, if so, how much diversity is needed to significantly improve a colony’s odds of surviving.” (more…)

Researchers ID Queens, Mysterious Disease Syndrome as Key Factors in Bee Colony Deaths

A new long-term study of honey bee health has found that a little-understood disease study authors are calling “idiopathic brood disease syndrome” (IBDS), which kills off bee larvae, is the largest risk factor for predicting the death of a bee colony.

“Historically, we’ve seen symptoms similar to IBDS associated with viruses spread by large-scale infestations of parasitic mites,” says Dr. David Tarpy, an associate professor of entomology at North Carolina State University and co-author of a paper describing the study. “But now we’re seeing these symptoms – a high percentage of larvae deaths – in colonies that have relatively few of these mites. That suggests that IBDS is present even in colonies with low mite loads, which is not what we expected.” The study was conducted by researchers from NC State, the University of Maryland, Pennsylvania State University and the U.S. Department of Agriculture (USDA).

National Deficit Outlook Unchanged Under Obama: UMD Policy Analysis

Public Policy’s Philip Joyce Offers Election Policy Fact Check

COLLEGE PARK, Md. – From a public policy point of view, the national debt accumulation since President Obama took office is largely a result of policies put in place prior to his inauguration, says a new analysis by University of Maryland expert Philip Joyce. He adds that Obama’s policies will make little impact in the debt over the next decade.

“The best that can be said about presidential fiscal policies thus far is that they would slow the bleeding, but they neither would stop it nor would they do much to heal the patient,” Joyce says.

The size of the debt has been one of the biggest issues of the presidential campaign, with Republicans arguing that the President has allowed the debt to rise out of control and Obama saying that he inherited the policies that led to an increase in debt and deficits. (more…)

Terrorism and the Olympics By-the-Numbers: Analysis from UMD-based START

COLLEGE PARK, Md. – History offers a warning, but no clear pattern on the true risk of terrorism at the Olympic Games, concludes a new report by the National Consortium for the Study of Terrorism and Responses to Terrorism (START) based at the University of Maryland.

The Olympic Games have been terror targets on three separate occasions since 1970, claiming 22 lives and wounding more than 100, the report says. It compiles and analyzes data from START’s comprehensive Global Terrorism Database (GTD).

“The heightened profile of these events might increase the likelihood of a terrorist attack while the heightened security and surveillance might decrease the likelihood of an attack,” explains START researchers and report co-author Erin Miller. (more…)
