Active hearing process in mosquitoes
A mathematical model has explained some of the remarkable features of mosquito hearing. In particular, the male can hear the faintest beats of the female's wings and yet is not deafened by loud noises.   view more (2009-11-20)

An atomic-level look at an HIV accomplice
Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity.   view more (2009-11-20)

No-entry zones for AIDS virus
The AIDS virus inserts its genetic material into the genome of the infected cell. Scientists of the German Cancer Research Center have now shown for the first time that the virus almost entirely spares particular sites in the human genetic material in this process. This finding may be useful for developing new, specific AIDS drugs.   view more (2009-11-13)

New brain findings on dyslexic children
The vast majority of school-aged children can focus on the voice of a teacher amid the cacophony of the typical classroom thanks to a brain that automatically focuses on relevant, predictable and repeating auditory information, according to new research from Northwestern University.   view more (2009-11-12)

'Escaped' proteins add to hearing loss in elderly, UF researchers find
Age-related hearing loss is the most common sensory disorder among the elderly. But scientists are still trying to figure out what cellular processes govern or contribute to the loss.   view more (2009-11-11)

Children with autism show slower pupil responses, MU study finds

Excitation pattern peak is more important determinant of vowel quality
The perceptions of five Chinese vowel /u, o, a, y, i/ and many perceptional phenomena can be explained well by the excitation pattern peaks. The study is reported in Science in China, Series F-Information Sciences, Volume 52,Issues 10 (Oct, 2009).   view more (2009-11-06)

Global challenges and opportunities in fighting HIV/AIDS and neglected diseases
Responding to the HIV/AIDS pandemic and tackling so-called neglected tropical diseases are the focus of the November/December 2009 edition of Health Affairs.   view more (2009-11-03)

Placental precursor stem cells require testosterone-free environment to survive
Trophoblast stem cells (TSCs), cells found in the layer of peripheral embryonic stem cells from which the placenta is formed, are thought to exhibit "immune privilege" that aids cell survivability and is potentially beneficial for cell and gene therapies.   view more (2009-10-29)

HIV care providers applaud Congress' extension of Ryan White program
Medical providers on the front lines of HIV care applaud the U.S. Congress for extending the Ryan White HIV/AIDS Program, helping to ensure that more than half a million low-income, uninsured, or underinsured people living with HIV/AIDS have access to lifesaving care.   view more (2009-10-22)

Research shows treating HIV-AIDS with interleukin-2 is ineffective
An international research team has demonstrated that treating HIV-AIDS with interleukin-2 (IL-2) is ineffective. As a result, the researchers recommend that clinical trials on this compound be stopped.    view more (2009-10-16)

Study finds nontuberculous mycobacteria lung disease on the rise in the United States
Nontuberculous mycobacteria (NTM) are environmental organisms found in both water and soil that can cause severe pulmonary (lung) disease in humans. Pulmonary NTM is on the rise in the United States, according to a large study of people hospitalized with the condition.   view more (2009-09-25)
