‘To the Mountaintop’: Journalist Discusses Social Justice Yesterday, Today, and Tomorrow

Award-winning journalist, activist, and author Charlayne Hunter-Gault told a packed audience at Yale that lessons learned from the civil rights movement still have relevance for current and future generations.

Hunter-Gault delivered a lecture titled “Social Justice, Equity, and Public Health” during a Branford College master’s tea on Feb. 5. (more…)

Americans Have Worse Health than People in Other High-Income Countries

WASHINGTON — On average, Americans die sooner and experience higher rates of disease and injury than people in other high-income countries, says a new report from the National Research Council and Institute of Medicine.

The report finds that this health disadvantage exists at all ages from birth to age 75 and that even advantaged Americans—those who have health insurance, college educations, higher incomes and healthy behaviors—appear to be sicker than their peers in other rich nations. (more…)

Battling Tuberculosis through Microsoft Technology

Microsoft Research develops biometric monitoring system to help patients complete tuberculosis treatment programs.

BANGALORE, India — Dec. 3, 2012 — Giri Prasad, a 33-year-old tailor who lives in Delhi, first noticed the pain below his ribs. He went to see a doctor, but when it didn’t subside, he traveled to the hospital where he eventually learned he had tuberculosis.

“There were many problems because first and foremost, I am the bread earner for the family,” he says. “If the bread earner falls ill, it is a real problem for those who are dependent on him. Here in the city the biggest problem is that if one falls sick, there is no other person who will come help.” (more…)

Mutation Breaks HIV’s Resistance to Drugs, Says MU Researcher

Doctors can improve treatment programs using this knowledge

COLUMBIA, Mo. – The human immunodeficiency virus (HIV) can contain dozens of different mutations, called polymorphisms. In a recent study an international team of researchers, including University of Missouri scientists, found that one of those mutations, called 172K, made certain forms of the virus more susceptible to treatment. Soon, doctors will be able to use this knowledge to improve the drug regimen they prescribe to HIV-infected individuals.

“The 172K polymorphism makes certain forms of HIV less resistant to drugs,” said Stefan Sarafianos, corresponding author of the study and a researcher at MU’s Bond Life Sciences Center. “172K doesn’t affect the virus’ normal activities. In some varieties of HIV that have developed resistance to drugs, when the 172K mutation is present, resistance to two classes of anti-HIV drugs is suppressed. We estimate up to 3 percent of HIV strains carry the 172K polymorphism.” (more…)

Combating Global Problems at BIARI

Some 140 participants and 30 visiting faculty from more than 45 countries arrived at Brown to take part in the Brown International Advanced Research Institutes (BIARI). The two-week program began June 11, 2012.

PROVIDENCE, R.I. [Brown University] — Some 140 participants and 30 visiting faculty from more than 45 countries arrived at Brown to take part in the Brown International Advanced Research Institutes (BIARI). Participants, who were chosen from a pool of more than 850 applicants, come from several countries, including Brazil, China, Nigeria, India, and Ethiopia.

The two-week program began Monday, June 11, 2012. Now in its fourth year, BIARI is centered around four two-week intensive institutes, convened concurrently by Brown faculty, in which participants and leading scholars in their fields share their research and develop new collaborative projects through sustained, high-level dialogue spanning disciplines and continents. This year’s institutes touched on global health and HIV/AIDS; theater and civil society; population and development; and climate change. (more…)

When Cells Hit the Wall: UCLA Engineers Put The Squeeze on Cells to Diagnose Disease

If you throw a rubber balloon filled with water against a wall, it will spread out and deform on impact, while the same balloon filled with honey, which is more viscous, will deform much less. If the balloon’s elastic rubber was stiffer, an even smaller change in shape would be observed.

By simply analyzing how much a balloon changes shape upon hitting a wall, you can uncover information about its physical properties.

Although cells are not simple sacks of fluid, they also contain viscous and elastic properties related to the membranes that surround them; their internal structural elements, such as organelles; and the packed DNA arrangement in their nuclei. Because variations in these properties can provide information about cells’ state of activity and can be indicative of diseases such as cancer, they are important to measure. (more…)

Project Aims To Improve HIV/AIDS Prevention Materials For African-American Women

African-American women make up a disproportionate number of HIV/AIDS cases in the United States. Researchers from North Carolina State University are trying to change that, leading a National Science Foundation project aimed at developing HIV/AIDS prevention materials that resonate with African-American female college students.

African-Americans represent approximately 14 percent of the U.S. population, but accounted for an estimated 44 percent of new HIV infections in 2009. The estimated rate of new HIV infections among African-American women was 15 times that of white women and over three times that of Latina women. (more…)

To Be A Scientist

*How Bob Vince changed the world*

Where does it begin, the act of becoming a scientist? Perhaps with a bowling ball, its finger holes packed with explosives, which when detonated, launch the ball into the air, cracking the otherwise pristine concrete walkway of your childhood home in four places, much to the consternation of your father. Or maybe with an explosion of homemade rocket fuel in your basement chemistry lab that scares your mother half to death. And all this before the troublesome teen years.

Bob Vince can’t be sure where his becoming a scientist began. But where it led changed the world. (more…)
