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…)
EAST LANSING, Mich. — Most of America’s urban cores were designed for walking but offer little in the way of supermarkets, healthy restaurants and other amenities for residents to walk to, according to a study led by a Michigan State University scholar.
The study is one of the first to show that poor residents living in declining urban neighborhoods want healthy food choices – evidenced by their willingness to travel long distances to find them. Past research has generally assumed that poor people will shop at whatever store is closest. (more…)
Despite the increasing awareness of the problem of obesity in the United States, most Americans don’t know whether they are gaining or losing weight, according to new research from the Institute for Health Metrics and Evaluation, also known at IHME, at the University of Washington.
Obesity increased in the U.S. between 2008 and 2009, but in response to the questions about year-to-year changes in weight that were included in the most widespread public health survey in the country, on average, people said that they lost weight. Men did a worse job estimating their own weight changes than women. And older adults were less attuned to their weight changes than young adults. The findings are being published in the article “In denial: misperceptions of weight change among adults in the United States” in the August edition of Preventive Medicine. (more…)
Fears of terrorism in Europe and the United States have deteriorated into an irrational suspicion of Muslims, which will continue until the West turns its critical eye inward, argues University of Chicago professor Martha Nussbaum in her new book, The New Religious Intolerance: Overcoming the Politics of Fear in an Anxious Age.
While fear is an important natural emotion, its self-centered nature makes it susceptible to irrational distortions that are harmful to others, writes Nussbaum, the Ernst Freund Distinguished Service Professor of Law and Ethics in the Law School and Philosophy. (more…)
New research from North Carolina State University shows that informal social networks play an important role when it comes to finding jobs in both the United States and Germany, but those networks are significantly more important for high-paying jobs in the United States – which may contribute to economic inequality.
“It is interesting to note that the open market system in the United States, with minimal labor regulations, actually sees people benefiting more from patronage – despite the expectation that open markets would value merit over social connections,” says Richard Benton, a Ph.D. student at NC State who co-authored the research.

COLUMBIA, Mo. – Marrying multiple husbands at the same time, or polyandry, creates a safety net for women in some cultures, according to a recent study by a University of Missouri researcher. Extra husbands ensure that women’s children are cared for even if their fathers die or disappear. Although polyandry is taboo and illegal in the United States, certain legal structures, such as child support payments and life insurance, fill the same role for American women that multiple husbands do in other cultures.
“In America, we don’t meet many of the criteria that tend to define polyandrous cultures,” said Kathrine Starkweather, doctoral student in MU’s Department of Anthropology in the College of Arts and Science. “However, some aspects of American life mirror polyandrous societies. Child support payments provide for offspring when one parent is absent. Life insurance allows Americans to provide for dependents in the event of death, just as secondary husbands support a deceased husband’s children in polyandrous societies.” (more…)
COLUMBIA, Mo. — One person dies every hour from melanoma skin cancer in the United States, according to the American Cancer Society. A technique known as photoacoustics can find some forms of melanoma even if only a few cancerous cells exist, but a recent study by University of Missouri researchers found that the technique was limited in its ability to identify other types of cancer. Attaching markers, called enhancers, to cancer cells could improve the ability of photoacoustics to find other types of cancer and could save lives thanks to faster diagnoses, but the technique is in its early stages.
“Eventually, a photoacoustic scan could become a routine part of a medical exam,” said Luis Polo-Parada, assistant professor of pharmacology and physiology and resident investigator at the MU Dalton Cardiovascular Research Center. “The technique doesn’t use X-rays like current methods of looking for cancer. It could also allow for much earlier detection of cancer. Now, a cancerous growth is undetectable until it reaches approximately one cubic centimeter in size. Photoacoustics could potentially find cancerous growths of only a few cells. Unfortunately, our research shows that, besides some cases of melanoma, the diagnostic use of photoacoustics still has major limitations. To overcome this problem, the use of photoacoustic enhancers like gold, carbon nanotubes or dyed nanoparticles is needed.” (more…)
Bounty hunting, or the practice of apprehending fugitives for a monetary reward, is often something that conjures up images of men or women who operates outside of the law and bring criminals to justice through legally ambiguous means. In reality however, bounty hunting, also known as skip tracing, is a necessary part of the modern criminal justice system in the United States. This article will serve as a basic explanation of how bounty hunters operate, their purpose in society and their basic day-to-day operations in bringing those who fail to appear in court to justice through legal means.
As a profession bounty hunting is something that is often romanticized by movies and other media. However, the job is actually a fairly technical and adheres to the same stringent due process laws that cops and courts are subject to. Bounty hunting is also a profession that depends on a thorough knowledge of laws and legal precedent, something that often requires a college-level education that many overlook. (more…)
