New research highlights intriguing studies on the acute danger that the H1N1 pandemic presents for children with this blood disorder, evaluations of both new and standard treatments for common complications of sickle cell disease, and an expansion of the current understanding of hemoglobin expression in red blood cells that may lead to new treatments.

A new study finds that children in military families suffer from more emotional and behavioral problems as the length of their parents' deployments grow. Researchers found that military children may suffer from more emotional and behavioral difficulties when compared to other American youths, with older children and girls struggling the most when a parent is deployed overseas.

Scientists are pushing to see how clean and green a diesel truck engine can be. Researchers have simultaneously cut nitrogen oxide and soot production, reducing pollutants in exhaust emissions to barely measurable levels. Their experimental engine nearly meets stringent requirements set to go into effect in 2014. They've also developed a probe for studying the growth of soot during combustion.

Human papillomavirus type 16, the most common cause of cervical cancer, silences a key signaling molecule of immune response in its host cells. Once the body's own immune defense is missing, the pathogens are able to infect the cells of the cervical mucosa even more successfully. Scientists have found out that the viral E6 oncogene is responsible for this mechanism.

Computer screen pop-ups may slow down your work more than you think. Although the actual interruption may only last a few moments, a new study shows that we then lose more time when we try to find our place and resume the task that was interrupted.

A new generation of optical sensors is enabling the development of robust, long-lasting, lightning-fast trace gas detectors for use in a wide range of industrial, security and domestic applications.

Scientists have discovered that the loss of a key segment of DNA can lead to severe childhood obesity. This is the first study to show that this kind of genetic alteration can cause obesity.

Using a new mathematical model of heart cells, investigators have shown how activation of a critical enzyme, calmodulin kinase II (CaM kinase), disrupts the electrical activity of heart cells. By targeting this enzyme's activity, it may be possible to prevent or treat heart disease and associated electrical rhythm disturbances.

New research shows that people equate large payments for participation in medical research with increased levels of risk. And when they perceive studies to be risky, they spend more time learning about the risks and nature of the study. Paper published this month in Social Science and Medicine suggests there is a "mismatch" between current research guidelines for setting compensation levels and the assumptions participants make about the levels of pay and risk.

Researchers have found very large RNA structures within previously unstudied bacteria that appear crucial to basic biological functions such as helping viruses infect cells or allowing genes to "jump" to different parts of the chromosome.
