The largely unnoticed collision of the global epidemics of HIV and tuberculosis has exploded to create a deadly co-epidemic that is rapidly spreading in sub-Saharan Africa. However, health systems cannot adequately diagnose, treat, or contain the co-epidemic due to unanswered scientific and medical questions, according to a new report. The report urges research and immediate action to thwart co-epidemic as threat of multi-drug resistant tuberculosis/HIV mounts. Latest Fuel Cell Material Advance Overcomes Low Humidity Conductivity
James McGrath, University Distinguished Professor of Chemistry at Virginia Tech, will announce his research group's latest development, a PEM material that retains conductivity during low humidity, during his plenary lecture at the Challenges for the Hydrogen Economy symposium during the 232nd National Meeting of the American Chemical Society in San Francisco. Blood Pressure Drugs Cut Death Rate In Type 2 Diabetes
The largest-ever study of treatments for type 2 diabetes has shown that a combination of two blood pressure lowering drugs reduced the risk of death, as well as the risks of heart and kidney disease. The scientists reported that the treatment reduced the likelihood of dying from the complications of diabetes by almost one-fifth. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." Relational Uncertainty Sparks Negativity In Marital Conversations
Spouses who experience doubts about their marriage, even weak doubts, make pessimisticjudgments about their partner's behavior in conversation. That's the conclusion of researchers who have conducted the first study to examine the link between relational uncertainty and conversation within marriage. Older Adults Not More Distractible, Research Shows
Despite previous research suggesting that older adults are more distractible, new research shows they are no more distractible than younger adults when asked to focus their attention on their sense of sight or sound, or when asked to switch their attention from one sense to the other. NASA Probes The Sources Of The World's Tiny Pollutants
Pinpointing pollutant sources is an important part of the ongoing battle to improve air quality and to understand its impact on climate. Scientists using NASA data recently tracked the path and distribution of aerosols -- tiny particles suspended in the air -- to link their region of origin and source type with their tendencies to warm or cool the atmosphere. Understanding Malarial Parasites
Scientists have constructed a chaperon interaction network for the parasite which provides, for the first time, a rational basis for the antimalarial effect of known drugs and highlights new proteins that can potentially be used in the fight against malaria. Several Years In Small Classes In Elementary School Yields Big Rewards
A new study involving a large sample of students followed for 13 years shows that four or more years in small classes in elementary school significantly increases the likelihood of graduating from high school, especially for students from low-income homes.
