Treating HIV in war zones -- Public health emergencies need rapid advice from WHO

... and on ART since December 2003, says: "I heard gun fire all through the night. When I had only five pills left I lost my appetite and felt desperate…but despite the uncertainty I continued to take my treatment at the correct hour… When I had only one pill left I had the courage to go out and seek som...

Iowa State scientists demonstrate first use of nanotechnology to enter plant cells

... not through endocytosis. In order to use the gene gun to introduce the nanoparticles to walled plant cells, the chemists made another clever modification on the particle surface. They synthesized even smaller gold particles to cap the nanoparticles. These "golden gates" not only prevented chemical leaka...

Prehistoric mystery organism verified as giant fungus

... the fact that he was never able to find a smoking gun in the form of reproductive structures that would convince the world that it was indeed a fungus," Hotton said. Co-authoring the Geology paper with Boyce, Hotton and Hueber himself were Marilyn Fogel, George Cody and Robert Hazen of the Carnegie I...

Ready, set, mutate?and may the best microbe win

...omic tools, it's a daunting task to find a smoking gun for Darwinian evolution. The problem lies in being able to say not just when and how a specific gene mutated but also how that one genetic change translated into real-world dominance of one population over another. Rice University biologists, using ...

Researchers develop portable 'vein finder' for faster, more accurate injections

...lengths and frequency. For example, a police radar gun sends microwave signals to a moving car, and when signals bounce back, the change in their frequency provides a measurement used to determine the vehicle's speed. Doppler ultrasound is similar, except that acoustical waves are transmitted. Compared...

MIT chemist discovers secret behind nature's medicines

... the size of one of its parts. "If an enzyme is a gun that fires to cause a reaction, then we wanted to know the mechanism that pulls the trigger," Drennan said. "In chemistry, we often have to look at 'molecules in, molecules out.' With halogenated natural products, though, we couldn't figure out how i...

DNA gene vaccine protects against harmful protein of Alzheimer's disease

...tein. The particles were then injected with a gene gun into the skin cells of the mice's ears using a blast of helium. After receiving 11 injections over several months, the mice showed a high level of antibodies to amyloid-beta 42, and a 60 percent to 77.5 percent reduction of plaques in their brains....

Researchers find gene that may be at root of potato blight

...nd Development Center in Wooster . "If you take a gun through the metal detector at an airport, the alarms go off," he said. "This gene (Avr3a) sends a signal alerting the plant that it is infected by the pathogen." Phytophthora infestans is the pathogen that causes late blight. For decades, controllin...
