Study offers clearest picture yet of how HIV defeats a cellular defender

CHAMPAIGN, Ill. -- A new study offers the first atomic-scale view of an interaction between the HIV capsid - the protein coat that shepherds HIV into the nucleus of human cells - and a host protein known as cyclophilin A. This interaction is key to HIV infection, researchers say. Read More

War and peace in the human gut: Probing the microbiome

Human well being often flourishes under conditions of cooperation with others and flounders during periods of external conflict and strife.

According to Athena Aktipis, a researcher at Arizona State University's Biodesign Institute, microbes within the body--collectively known as the microbi... Read More

Lung ultrasound may be a safe substitute for chest X-ray when diagnosing pneumonia in children

Lung ultrasound has been shown to be highly effective and safe for diagnosing pneumonia in children and a potential substitute for chest X-ray, according to a study conducted at the Icahn School of Medicine at Mount Sinai. Results are currently published in the medical journal Chest. Read More

Wealth of unsuspected new microbes expands tree of life

Researchers at the University of California, Berkeley, who have discovered more than 1,000 new types of bacteria and Archaea over the past 15 years lurking in Earth's nooks and crannies, have dramatically rejiggered the tree to account for these microscopic new life forms. Read More

Scientists identify effective and novel mechanisms to block chikungunya virus

December 10, 2015, San Francisco, CA--Scientists looking at the antiviral mechanisms of two previously identified human monoclonal antibodies have found they potently inhibit chikungunya virus (CHIKV) at multiple stages of infection. Read More

Researchers Sequence Genome from 1979 Russian Anthrax Outbreak

Bacillus anthracis had been studied by multiple countries as a potential biological weapon because of the stability of its spores and its ability to cause acute pulmonary disease. While offensive anthrax weapons development programs were halted in the United States and United Kingdom in the ... Read More

UNC School of Medicine researchers prove HIV targets tissue macrophages

CHAPEL HILL, N.C. - Investigators in the Division of Infectious Diseases at the University of North Carolina School of Medicine have clearly demonstrated that HIV infects and reproduces in macrophages, large white blood cells found in the liver, brain and connective tissues of the body.
