COLLEGE PARK, Md. – New research out of the University of Maryland School of Public Health shows that exercise may improve cognitive function in those at risk for Alzheimer’s by improving the efficiency of brain activity associated with memory. Memory loss leading to Alzheimer’s disease is one of the greatest fears among older Americans. While some memory loss is normal and to be expected as we age, a diagnosis of mild cognitive impairment, or MCI, signals more substantial memory loss and a greater risk for Alzheimer’s, for which there currently is no cure. 

The study, led by Dr. J. Carson Smith, assistant professor in the Department of Kinesiology, provides new hope for those diagnosed with MCI. It is the first to show that an exercise intervention with older adults with mild cognitive impairment (average age 78) improved not only memory recall, but also brain function, as measured by functional neuroimaging (via fMRI).The study, led by Dr. J. Carson Smith, assistant professor in the Department of Kinesiology, provides new hope for those diagnosed with MCI. It is the first to show that an exercise intervention with older adults with mild cognitive impairment (average age 78) improved not only memory recall, but also brain function, as measured by functional neuroimaging (via fMRI). The findings are published in the Journal of Alzheimer’s Disease.

“We found that after 12 weeks of being on a moderate exercise program, study participants improved their neural efficiency – basically they were using fewer neural resources to perform the same memory task,” says Dr. Smith. “No study has shown that a drug can do what we showed is possible with exercise.”

Recommended Daily Activity: Good for the Body, Good for the Brain
Two groups of physically inactive older adults (ranging from 60-88 years old) were put on a 12-week exercise program that focused on regular treadmill walking and was guided by a personal trainer.  Both groups – one which included adults with MCI and the other with healthy brain function – improved their cardiovascular fitness by about ten percent at the end of the intervention. More notably, both groups also improved their memory performance and showed enhanced neural efficiency while engaged in memory retrieval tasks.

The good news is that these results were achieved with a dose of exercise consistent with the physical activity recommendations for older adults. These guidelines urge moderate intensity exercise (activity that increases your heart rate and makes you sweat, but isn’t so strenuous that you can’t hold a conversation while doing it) on most days for a weekly total of 150 minutes.

Measuring Exercise’s Impact on Brain Health and Memory
One of the first observable symptoms of Alzheimer’s disease is the inability to remember familiar names. Smith and colleagues had study participants identify famous names and measured their brain activation while engaged in correctly recognizing a name – e.g., Frank Sinatra, or other celebrities well known to adults born in the 1930s and 40s. “The task gives us the ability to see what is going on in the brain when there is a correct memory performance,” Smith explains.

Tests and imaging were performed both before and after the 12-week exercise intervention. Brain scans taken after the exercise intervention showed a significant decrease in the intensity of brain activation in eleven brain regions while participants correctly identified famous names. The brain regions with improved efficiency corresponded to those involved in the pathology of Alzheimer’s disease, including the precuneus region, the temporal lobe, and the parahippocampal gyrus.

The exercise intervention was also effective in improving word recall via a “list learning task,” i.e., when people were read a list of 15 words and asked to remember and repeat as many words as possible on five consecutive attempts, and again after a distraction of being given another list of words.

“People with MCI are on a very sharp decline in their memory function, so being able to improve their recall is a very big step in the right direction,” Smith states.

The results of Smith’s study suggest that exercise may reduce the need for over-activation of the brain to correctly remember something.  That is encouraging news for those who are looking for something they can do to help preserve brain function.

Dr. Smith has plans for a larger study that would include more participants, including those who are healthy but have a genetic risk for Alzheimer’s, and follow them for a longer time period with exercise in comparison to other types of treatments. He and his team hope to learn more about the impact of exercise on brain function and whether it could delay the onset or progression of Alzheimer’s disease.

Some were the freed slaves of conscience-stricken Quakers. Others were freed by a sea captain in his will. Still others were freed by a slave midwife who bought freedom for herself and her family. Together, here in Talbot County on the Eastern Shore, they may have given birth to what scholars at the University of Maryland and Morgan State suspect could be the oldest enclave of free African Americans, and possibly the oldest existing black neighborhood, in the country.

Piece by piece, University of Maryland archaeologists, historians from Morgan State, and the local community are uncovering the history of The Hill, a community they believe to be the earliest settlement of free African Americans in the United States, dating to 1790.

 

Starburst Wind Keeps Galaxies 'Thin'

Unlike humans, galaxies don’t have an obesity problem. In fact there are far fewer galaxies at the most massive end of the galactic scale than expected and scientists have long sought to explain why. A new, UMD-led study published in the journal Nature suggests that one answer lies in a kind of feast and fast sequence through which large galaxies can keep their mass down.COLLEGE PARK, Md. -- Unlike humans, galaxies don’t have an obesity problem. In fact there are far fewer galaxies at the most massive end of the galactic scale than expected and scientists have long sought to explain why. A new, UMD-led study published in the journal Nature suggests that one answer lies in a kind of feast and fast sequence through which large galaxies can keep their mass down.

Galaxies become more massive by ‘consuming’ vast clouds of gas and turning them into new stars. The new study shows in unprecedented detail how a burst of star formation in a galaxy can blow most of the remaining star-building gas out to the edge of the galaxy, resulting in a long period of starvation during which few new stars are produced.

“For the first time, we can clearly see massive concentrations of cold molecular gas being jettisoned by expanding shells of intense pressure created by young stars,” says lead author Alberto Bolatto of the University of Maryland. “The amount of gas we measure gives us very convincing evidence that some growing galaxies blow out more gas than they take in, slowing star formation down to a crawl.”

The team of astronomers used the new Atacama Large Millimeter/submillimeter Array (ALMA), a giant radio telescope in the high desert of northern Chile, to discover billowing columns of cold, dense gas being pushed out of starburst galaxy NGC 253, also known as the Silver Dollar or Sculptor Galaxy. In starburst galaxies, stars form about 100 times faster than in more normal galaxies like our Milky Way.

NGC 253 – with its slightly askew orientation – offers astronomers an excellent view of the star formation clusters near the galaxy’s center, clusters that turn out to be the point of departure for material being pushed from the galaxy.

“ALMA is opening a new window for observations of galactic winds,” says Sylvain Veilleux, also at the University of Maryland and a coauthor on the paper. “Winds have the potential to be incredibly disruptive and carry away a significant fraction of the star-forming material of a galaxy.”

The team says their results may help explain the universe’s surprising paucity of high-mass galaxies. Computer models indicate that old red galaxies, which are far more massive than the Milky Way, should be considerably more common than they are. In their youth, these galaxies likely ejected a large fraction of their gas that would have otherwise formed stars.

Gas can be removed from a galaxy in two ways. One is through the action of a central, supermassive black hole, called an active galactic nucleus.  Material is pulled into the black hole, becomes superheated and produces powerful jets or wide-angle winds that can propel material far from the galactic disk. However, evidence suggests that the black hole at the center of NGC 253 is not currently active.

The other way to potentially blow gas out of a galaxy is through galactic winds generated by star formation, but previously this had not been observed with enough resolution or sensitivity to measure the outflow of gas or its reductive impact on subsequent star formation.

As new stars form they exert powerful destructive influences on their environment. Initially, their light and winds of particles push on the surrounding gas. Later, if they are massive enough, stars explode as supernovas, a process that further drives the surrounding material away from the stellar birthplace. The current study indicates that in NGC 253, the concentration of hundreds or thousands of such destructive stars in one region is responsible for launching powerful flows of gas out of the galaxy.NASA image of NGC 253

Previous X-ray spectrum observations of NGC 253 have shown gas made of hot ionized hydrogen atoms streaming away from its star-forming regions. However, alone this insubstantial gas would have little if any impact on the fate of the galaxy and its ability to form future generations of stars. The new ALMA data show the far-more-dense molecular gas getting its initial “kick” from the formation of new stars and then being swept along with the thin, hot gas on its way to the galactic halo.
 
Using only a portion of its eventual full complement of 66 antennas, ALMA measured the mass and motion of carbon monoxide (CO) in the gas ejected from the central regions of this galaxy. The researchers determined that vast quantities of molecular gas – likely 9 times the mass of our Sun and possibly much more – were being ejected from the galaxy each year. At this rate, the galaxy could run out of gas and star formation slow to a crawl as in as few as 60 million years.
 
The researchers also determined that the gas is traveling somewhere between 25 to 155 miles (40 to 250 kilometers) per second, streaming approximately 1,500 light-years above and below the disk.  This may not be fast enough for the gas to reach escape velocity from the galaxy. If not, the gas will likely get suspended in the galactic halo for many millions of years.
 
 “More studies with the full ALMA array will help us figure out the ultimate fate of the gas carried away by the wind,” said Adam Leroy with the National Radio Astronomy Observatory, a facility of the National Science Foundation (NSF). “This will help us understand whether these starburst-driven winds recycle or truly remove star forming material.”

Bolatto agrees, but says: “Probably in a galaxy like this, the gas is pulled back into the heart of the galaxy, perhaps after several hundred million years. Star formation then takes off again and the whole process repeats itself.”

The National Science Foundation (NSF) provided core funding for this research through multiple grants to the university-based U.S. scientists as well as through NSF support of NRAO and ALMA construction and operations.

“Understanding how galaxies can evolve so radically and so dramatically is one of the hottest topics in astronomy today,” said Dan Evans, NSF program officer. “This work will have far-reaching implications for our understanding of the evolution of the cosmos. The result also is a true testament to the partnerships forged over many years between the University of Maryland research team, NSF and its international partners in the ALMA Project.

Study Shows Common Chemicals Harm Honey Bees' Health

Researchers collect pollen samples from honey bee hives used to pollinate blueberries in Maine. Photo: Michael Andree COLLEGE PARK, Md - Commercial honey bees used to pollinate crops are exposed to a wide variety of agricultural chemicals, including common fungicides which impair the bees’ ability to fight off a potentially lethal parasite, according to a new study by researchers at the University of Maryland and the U.S. Department of Agriculture.

The study, published July 24 in the online journal PLOS ONE, is the first analysis of real-world conditions encountered by honey bees as their hives pollinate a wide range of crops, from apples to watermelons.

The researchers collected pollen from honey bee hives in fields from Delaware to Maine. They analyzed the samples to find out which flowering plants were the bees’ main pollen sources and what agricultural chemicals were commingled with the pollen. The researchers fed the pesticide-laden pollen samples to healthy bees, which were then tested for their ability to resist infection with Nosema ceranae – a parasite of adult honey bees that has been linked to a lethal phenomenon known as colony collapse disorder.

On average, the pollen samples contained 9 different agricultural chemicals, including fungicides, insecticides, herbicides and miticides. Sublethal levels of multiple agricultural chemicals were present in every sample, with one sample containing 21 different pesticides. Pesticides found most frequently in the bees’ pollen were the fungicide chlorothalonil, used on apples and other crops, and the insecticide fluvalinate, used by beekeepers to control Varroa mites, common honey bee pests.

In the study’s most surprising result, bees that were fed the collected pollen samples containing chlorothonatil were nearly three times more likely to be infected by Nosema than bees that were not exposed to these chemicals, said Jeff Pettis, research leader of the USDA’s Bee Research Laboratory and the study’s lead author. The miticides used to control Varroa mites also harmed the bees’ ability to withstand parasitic infection.

Beekeepers know they are making a trade-off when they use miticides,  said University of Maryland researcher Dennis vanEngelsdorp, the study’s senior author. The chemicals compromise bees’ immune systems, but the damage is less than it would be if mites were left unchecked. But the study’s finding that common fungicides can be harmful at real world dosages is new, and points to a gap in existing regulations, he said.

“We don’t think of fungicides as having a negative effect on bees, because they’re not designed to kill insects,” vanEngelsdorp said. Federal regulations restrict the use of insecticides while pollinating insects are foraging, he said, “but there are no such restrictions on fungicides, so you’ll often see fungicide applications going on while bees are foraging on the crop. This finding suggests that we have to reconsider that policy.”

In an unexpected finding, most of the crops that the bees were pollinating appeared to provide their hives with little nourishment. Honey bees gather pollen to take to their hives and feed their young. But when the researchers collected pollen from bees foraging on native North American crops such as blueberries and watermelon, they found the pollen came from other flowering plants in the area, not from the crops. This is probably because honey bees, which evolved in the Old World, are not efficient at collecting pollen from New World crops, even though they can pollinate these crops.

The study’s findings are not directly related to colony collapse disorder, the still-unexplained phenomenon in which entire honey bee colonies suddenly die. However, the researchers said the results shed light on the many factors that are interacting to stress honey bee populations.

When College Diversity Delivers Benefits: UMD Study

COLLEGE PARK, Md. – The benefits of race-conscious college admissions are only fully realized under certain conditions, concludes new University of Maryland-led research. To stimulate meaningful cross-racial engagement, incoming freshman classes should reflect both racial and socio-economic diversity, the researchers report.

The peer-reviewed study appears in the June 2013 issue of the "American Educational Research Journal." The researchers say their study is the first to test empirically how socio-economic diversity affects racial interaction in colleges.

"Social class and race not only affect who goes to college, but what actually happens to students once they begin the journey of learning together," says lead author Julie J. Park, an assistant professor of education at the University of Maryland (UMD)."Social class and race not only affect who goes to college, but what actually happens to students once they begin the journey of learning together," says lead author Julie J. Park, an assistant professor of education at the University of Maryland (UMD). "Socio-economic diversity matters, not only because we need to broaden access to universities, but because it better equips these institutions to support racial diversity. A broader mix of students helps encourage more fluid interactions."

Park's team analyzed questionnaires filled out by more than 15,000 students at 102 U.S. colleges and universities on their campus interactions in and out of the classroom, including contacts with students from different races and social-economic backgrounds. Students reported as freshman and then again four years later as seniors.

The researchers found that students who reported higher levels of interaction with those from different socio-economic backgrounds also had significantly higher levels of contacts with other races, and an overall higher level of mixing with students from diverse backgrounds.

These findings "indicate that both socioeconomic and racial diversity are essential to promoting a positive campus racial climate," the researchers write. "Racial and socioeconomic diversity, while interrelated, are not interchangeable."

Park explains that white students from lower class backgrounds tend to have more experiences with people from different backgrounds due to the racial composition of American high schools.

"For one thing, sharing similar socio-economic backgrounds provides a way for students of different races to find common ground," Park adds. "Socio-economic diversity in combination with racial diversity creates a safer, more level playing field where people can meet and learn from each other."

The study's findings have practical implications for college admissions policies. "In order to better support both racial and socioeconomic diversity, selective and highly selective colleges need to increase efforts and dedicate additional resources toward recruiting, admitting, and supporting greater numbers of academically talented low-income students of all races and ethnicities," the authors write.

The study is the latest in Park's research, which focuses on diversity in higher education. She has a new book out that echoes the findings of this study, "When Diversity Drops: Race, Religion, and Affirmative Action in Higher Education." It examines the impact in California of Proposition 209, which banned affirmative action statewide.

COLLEGE PARK, Md. – A University of Maryland-led research team is working to help diplomats, military personnel, global managers and others who operate abroad to peer inside the minds of people from very different cultures.

"Some cultures are 'loose' and others very 'tight' – quick to spot and react to violations of social norms. Yet we know very little about how these vast cultural are realized in the brain," says University of Maryland cross-cultural psychologist Michele Gelfand, who is leading the interdisciplinary research team.With a three-year, $813,000 grant from the Department of Defense researchers will literally get inside the heads of people from various cultures to study the underlying neural-biological processes associated with cultural permissiveness versus restrictiveness.

"Some cultures are 'loose' and others very 'tight' – quick to spot and react to violations of social norms. Yet we know very little about how these vast cultural differences are realized in the brain," says University of Maryland cross-cultural psychologist Michele Gelfand, who is leading the interdisciplinary research team. "This work builds upon an exciting new field of cultural neuroscience to examine how differences in the strength of norms across the globe are 'embrained.'"

Gelfand's team will use brain measurements to help explain and predict a wide range of cultural differences, from self-control to creativity to cooperation.Gelfand's team will use brain measurements to help explain and predict a wide range of cultural differences, from self-control to creativity to cooperation. Though the field is in its infancy, she says it can advance understanding of group identities, cultural norms and belief systems.
 
"Social norms, though omnipresent in our everyday lives, are highly implicit," Gelfand says. "This research has the potential to facilitate the development of theoretical models and measures with improved predictive power. It will advance our understanding of the connection between culture, brain, and behavior."

The team will focus on developing tools to assess the strength of social norms, as well as policy recommendations for managing clashes of moralities, and techniques for better intercultural interaction.

Gelfand's co-investigators are Luiz Pessoa, who directs the University of Maryland Neuroimaging Center, Shinobu Kitayama, director of the University of Michigan Culture and Cognition Program, and Klaus Boehnke, a professor of social science methodology at Bremen, Germany's Jacobs University.

The research builds upon on an earlier 33-nation study in Science, in which a Gelfand-led team assesses the degree to which countries are restrictive or permissive and the factors that made them that way.

The research grant was awarded by the Defense Department's Minerva Initiative, which aims to improve the department's basic understanding of the social, cultural, behavioral, and political forces that shape regions of the world of strategic importance to the United States. The UMD project is one of only 14 funded by Minerva from a total pool of 280.

Gelfand received a prior Minerva grant in 2012 to study radicalization and a MURI grant in 2008 to study culture and negotiation in the Middle East. She can be contacted at mgelfand@umd.edu.

Maryland Agriculture is $8.25 Billion Industry

COLLEGE PARK, Md. - The impact of agriculture on Maryland’s economy amounts to $8.25 billion annually, according to a recent study published by the Department of Agricultural and Resource Economics in the College of Agriculture and Natural Resources at the University of Maryland.

Professor Loretta LynchThe study, conducted by Professor Loretta Lynch and graduate student Jeffrey Ferris, looks beyond the revenue generated from farm products ($1.8 billion) and takes an in-depth look at how the agricultural and forestry industries weave their way into nearly every sector of Maryland’s robust economy.

Graduate student Jeffrey Ferris“While agriculture and forestry uses occupy 66 percent of Maryland’s land, agriculture only accounts for less than one-percent of the state’s gross domestic product,” says Loretta Lynch, Ph.D., co-author of the study and Director of the Center for Agricultural and Resource Policy at UMD. “We suspected, however, that evaluating the ripple effects generated by agriculture on Maryland’s economy would tell us a different story.”

Using an input-output analysis, the study takes into account the numerous industries that provide supplies and services necessary to process, manufacture and package products grown and harvested from Maryland’s farms and forests. UMD researchers found that for every dollar generated directly by agriculture or forestry industries, 45 cents was added to other sectors in the state; and, for every five jobs generated in these industries, three additional jobs were created around the state. The total economic impact of Maryland agriculture amounted to $8.25 billion annually and 45,600 jobs.

The study was commissioned by Cheng-i Wei, Dean of the College of Agriculture and Natural Resources at the University of Maryland. “Agriculture is a part of Maryland’s economy that is often overlooked and underestimated but this study reinforces that it is essential to our state’s economic health,” says Wei, Ph.D. “It is important that we understand the full impact of agriculture so that we continue to discover innovative ways to keep the industry prosperous and train the next generation of leaders who will preserve it.”

While the number of farms in the state continues to decline, farmers are adapting, modernizing and becoming highly efficient, producing more with less for local, regional, national and international markets.The study, the first of its kind since 2005, also highlights the changing face of agriculture in Maryland. While the number of farms in the state continues to decline, farmers are adapting, modernizing and becoming highly efficient, producing more with less for local, regional, national and international markets. Steady profits, however, are necessary to keep Maryland operations from shutting down and causing a snowball effect on the state’s economy.

“The decline of the agricultural and forestry sectors would have an impact on not just farm families and agriculturally based businesses,” the study states. “It would ripple out to the entire economy, causing distress to workers in many sectors, and losses to taxpayers, businesses, and others who benefit from a strong Maryland economy.”
