Scanning electromicrograph of an HIV-infected T cell/NIAID
Almost 37 million people around the world are now infected with human immunodeficiency virus (HIV), the virus that causes AIDS . But many don’t know they are infected or lack access to medical care. Even though major strides have been made in treating the infection, less than half receive antiretroviral therapy (ART) that could prevent full-blown AIDS and reduce the likelihood of the virus being transmitted to other people. Now, a new report restores hope that an end to this very serious public health challenge could be within reach—but that will require a major boost in commitment and resources.
The study conducted by an NIH-funded research team evaluated the costs and expected life-saving returns associated with ambitious goals for HIV testing and treatment, the so-called 90-90-90 program, issued by the Joint United Nations Programme on HIV/AIDS (UNAIDS) in 2014 . The new analysis, based on HIV disease progression and treatment data in South Africa, finds that those goals, though expensive to implement, can be achieved cost-effectively, potentially containing the AIDS epidemic and saving many millions of lives around the globe.
If you follow my blog, you know that I like to feature spectacular images that scientists have created during the course of their research. These images are rarely viewed outside the lab, but some are so worthy of artistic merit and brimming with educational value that they deserve a wider audience. That’s one reason why the Federation of American Societies for Experimental Biology (FASEB) launched its BioArt contest. Of the 12 winners in 2013, I’m proud to report that 11 received support from NIH. In fact, I’m so proud that I plan to showcase their work in an occasional series entitled “Snapshots of Life.” Continue reading to see the first installment—enjoy! Continue reading →
This stunning picture of a human bone cancer cell won artistic accolades: 3rd place in the Nikon Small World Competition. DNA, the blueprint of life, is actually blue in this photo. The yellow squiggles are little powerhouses called mitochondria that generate ATP ‘fuel’ for the cell. The purple wisps are filaments of actin, which help the cell move, keep its shape, and traffic chemicals from one part of the cell to another.
