A University of Illinois at Chicago ecologist has tied changes in head shape and overall size of rodents to human population density and climate change. The finding is reported by Oliver Pergams, UIC research assistant professor of biological sciences, in PLoS One.

An international team of scientists with divergent views on ocean ecosystems has found that efforts to rebuild many of the world's fisheries are worthwhile and starting to pay off in many places around the world. Their study puts into perspective recent reports predicting a total collapse of global fisheries within 40 years.
While policymakers across of the globe are relying on environmental restoration projects to fuel emerging market-based environmental programs, an article in the Science by ecologists warns that these programs still lack the scientific certainty needed to ensure that restoration projects deliver the environmental improvements being marketed.
In the paper, "Mathematical Biology Education: Beyond Calculus," which is featured in the July 31, 2009 issue of Science, VBI Professor Reinhard Laubenbacher and Sweet Briar College Mathematical Sciences Professor Raina Robeva highlight algebraic models as one of the diverse mathematical tools needed in the professional development of up-and-coming life scientists. Despite this critical need, the authors explain, algebraic models have played a less substantial role in undergraduate curricula than other methods.
In the five months since passage of the American Recovery and Reinvestment Act of 2009 (ARRA), thousands of research-related awards have been made, supporting important scientific efforts across the country. ARRA delivered the largest increase in basic research funding in American history - $21.5 billion. The bulk of the money is for scientific research and education projects, while $3.5 billion is allocated for research facilities and capital equipment.
MINNEAPOLIS / ST. PAUL (July 29, 2009) –University of Minnesota Project Eating Among Teens (EAT) researchers have identified factors that may increase overweight adolescents' risk of engaging in extreme weight control behaviors such as self-induced vomiting, the use of diet pills, laxatives, and diuretics, as well as binge eating.
By linking data from the alloy composition of modern sculptures with parameters from art history, Dr. Marcus Young from Northwestern University together with collaborators from the Art Institute of Chicago, have classified the unique composition profiles of cast bronze sculptures by major European artists of the first half of the 20th century, profiles which could be used as another method to identify, date and even authenticate sculptures. Their findings1 are published online in Springer's journal, Analytical & Bioanalytical Chemistry.
PHILADELPHIA – Nanoparticle delivery of diphtheria toxin-encoding DNA selectively expressed in ovarian cancer cells reduced the burden of ovarian tumors in mice, and researchers expect this therapy could be tested in humans within 18 to 24 months, according to a report in Cancer Research, a journal of the American Association for Cancer Research.
Patients with the autoimmune disease systemic lupus erythematosus (SLE) have an increased risk of infection, due to both disturbances in their immune responses and treatment with immunosuppressive drugs. Because morbidity and mortality related to influenza are increased in immunocompromised patients, it is recommended that patients with SLE get annual flu shots, which are safe and do not increase disease activity.
WASHINGTON, D.C. – The Obama Administration has an opportunity to fundamentally reformulate United States space policies that are anchored in Cold War-era mindsets, according to the director of an American Academy of Arts and Sciences study.
COLUMBIA, Mo. – Vaccines to protect against sexually transmitted diseases, including HIV and herpes, are being developed and may soon be available to college students. However, limited research has been conducted to determine if students will accept the vaccines once they are available. In a new study, a University of Missouri researcher has found that students who feel invulnerable, or invincible, to physical harm are unlikely to get an HIV vaccine. Alternately, students who feel invulnerable to psychological harm are more likely to get the vaccine.
If the future of entertainment is interactive media, some minorities are still headed back to the past.
The first comprehensive survey of video game characters, encompassing the top 150 games in a year across nine platforms and all rating levels, and weighted by each title's popularity, shows that the video game industry does no better than television in representing American society.
In some cases, video games do worse, said study leader Dmitri Williams, a social psychologist and assistant professor at the USC Annenberg School for Communication.
CHAMPAIGN, Ill. – The Latino population in the United States is expected to triple by 2050, according to projections from the U.S. Census Bureau. And along with that growth, says University of Illinois professor Lydia Buki, will come a rise in the number of individuals from that population who are diagnosed with cancer.
In particular, based on current statistics, Buki expects that diagnoses of breast and cervical cancers among Latinas will increase significantly.
Overall, 4 percent of African American patients and 34 percent of white patients were HPV positive. Cullen said the survival difference was entirely due to HPV status, as survival rates were similar among HPV-negative patients.
Scott Lippman, M.D., chair of the Department of Clinical Cancer Prevention at the University of Texas M. D. Anderson Cancer Center and editor-in-chief of Cancer Prevention Research called the study "practice changing."
Chicago, IL (July 29, 2009) – The American Academy of Cosmetic Surgery announces the results of its 2009 Less Common Cosmetic Procedures consumer survey. While the media has coined these cosmetic procedures as 'fringe' and made it seem that they are in high demand, it is important to clarify the facts. The results reveal that less common cosmetic procedures are generally over-hyped and over-analyzed.
