(Press-News.org) Alexandria, VA – In 2010, the world reached a milestone: The number of people living in urban areas reached 50 percent. This monumental shift from rural to urban living comes with consequences. Growing urban populations will have to learn to efficiently deal with increased demands for energy, transportation, sanitation, food and water while balancing the environmental impacts of such densely populated regions. Currently, 75 percent of global carbon dioxide emissions from fossil fuels come from cities, which cover just 3 percent of Earth's land surface. As megacities continue to grow, how will their ever-increasing emissions impact our planet?
Now, the Megacities Project – an international pilot project involving universities, as well as city, state, federal and international agencies – is working to improve local carbon monitoring and modeling to find out, in detail, where carbon emissions originate. This type of information will help cities understand what sectors unique to them contribute the most to their greenhouse gas emissions. Learn how megacities such as Paris and Los Angeles are taking the initiative to reduce their carbon emissions online at http://www.earthmagazine.org/article/carbon-and-city-tracking-emissions-megacities.

Reactions to HIV drug have autoimmune cause, reports AIDS journal
2012-05-23
Philadelphia, Pa. (May 22, 2012) – Potentially severe hypersensitivity reactions to the anti-HIV drug abacavir occur through an autoimmune mechanism, resulting from the creation of drug-induced immunogens that are attacked by the body's immune system, according to a study published online by the journal AIDS, official journal of the International AIDS Society. AIDS is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.
The study is the first to explain how hypersensitivity reactions to abacavir develop in genetically predisposed patients—and suggests ...
Researchers take virus-tracking software worldwide
2012-05-23
A biomedical informatics researcher who tracks dangerous viruses as they spread around the globe has restructured his innovative tracking software to promote even wider use of the program around the world.
Associate Professor Daniel Janies, Ph.D., an expert in computational genomics at the Wexner Medical Center at The Ohio State University (OSU), is working with software engineers at the Ohio Supercomputer Center (OSC) to expand the reach of SUPRAMAP (supramap.org), a web-based application that synthesizes large, diverse datasets so that researchers can better understand ...
Doing the tooth implant 2-step
2012-05-23
Periodontists routinely grow bone in the mouth to guarantee a stable environment for teeth and tooth implants. But whether it's better to build up bone before placing the implant, or to simply place the implant and allow bone to grow around it, has been a subject of considerable medical debate.
Now Prof. Zvi Artzi of Tel Aviv University's Maurice and Gabriela Goldschleger School of Dentistry at the Sackler Faculty of Medicine has completed a study that concludes the two-step method is the more effective alternative — building bone first, then implanting and allowing ...
Wrongful convictions can be reduced through science, but tradeoffs exist
2012-05-23
WASHINGTON – Many of the wrongful convictions identified in a report this week hinged on a misidentified culprit — and a new report in a top journal on psychological science reveals the paradox of reforms in eyewitness identification procedure. In our efforts to make sure that good guys don't get locked up, we could let more bad guys go.
In the May issue of Perspectives on Psychological Science, a journal of the Association for Psychological Science, leading scholars in psychology and the law explore and debate various aspects of eyewitness identification procedures, ...
New TB test promises to be cheap and fast
2012-05-23
Biomedical engineers at UC Davis have developed a microfluidic chip to test for latent tuberculosis. They hope the test will be cheaper, faster and more reliable than current testing for the disease.
"Our assay is cheaper, reusable, and gives results in real time," said Ying Liu, a research specialist working with Professor Alexander Revzin in the UC Davis Department of Biomedical Engineering.
The team has already conducted testing of blood samples from patients in China and the United States.
About one-third of the world's population is infected with the bacteria ...

Newly discovered breast milk antibodies help neutralize HIV
2012-05-23
DURHAM, N.C. – Antibodies that help to stop the HIV virus have been found in breast milk. Researchers at Duke University Medical Center isolated the antibodies from immune cells called B cells in the breast milk of infected mothers in Malawi, and showed that the B cells in breast milk can generate neutralizing antibodies that may inhibit the virus that causes AIDS.
HIV-1 can be transmitted from mother to child via breastfeeding, posing a challenge for safe infant feeding practices in areas of high HIV-1 prevalence. But only one in 10 HIV-infected nursing mothers is known ...
CONSUMER ALERT: ConsignPro Contributes to Parents' Ability to Stretch Budgets
2012-05-23
While it is hardly unusual for families to live on tight budgets, many families have found those budgets growing even tighter in recent years. After an extended period of economic tumult, recovery is beginning to happen slowly but surely--just as gasoline prices see major spikes. All of these factors have left parents and families looking to cut costs like never before, and a new report highlights one way in which families are doing just that--by purchasing clothing not from designer clothing boutiques or name-brand stores, but from consignment stores. Families across the ...
Track Atlantic bluefin tuna to learn migration, habitat secrets
2012-05-23
AMHERST, Mass. – New fish-tagging studies of young bluefin tuna in Atlantic waters off New England by researchers at the University of Massachusetts Amherst are offering the first fishery-independent, year-round data on dispersal patterns and habitat use for the popular game fish. The availability of miniaturized pop-up satellite tags suitable for smaller (two- to five-year-old) fish helped make the research possible.
Fisheries oceanographer Molly Lutcavage and lead author Benjamin Galuardi say the work shows that scientists now have tools to directly observe bluefin ...
