In the Sept. 13 issue of The Lancet, Johns Hopkins and Ugandan researchers report final results of a study showing that a safe, simple and inexpensive treatment reduces transmission of HIV from mothers to babies during childbirth and the first few weeks of life, offering a good chance to curb the spread of HIV.
In their study of more than 600 women in Uganda, giving one dose of nevirapine, a common HIV-fighting drug, to HIV-positive mothers during labor, and one dose to their newborns, reduced transmission by 41 percent, compared to a multi-dose regimen of the drug zidovudine, commonly called AZT. Africa is home to roughly 30 million HIV-positive people, about 3 million of whom are pregnant women. The report documents all the babies health at 6 to 8 weeks and at 18 months.
"This use of nevirapine, if widely implemented, has the potential to prevent several hundred thousand new infections every year," says J. Brooks Jackson, M.D., director of pathology at the Johns Hopkins School of Medicine. "This regimen is extremely simple, safe and inexpensive, but access to HIV testing and counseling remains a huge obstacle. Fortunately, the recent availability of funds for HIV prevention and treatment for Africa from the Bush AIDS relief plan will likely make a huge difference in the implementation of this nevirapine regimen."

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
