Scientists have found that the soft palate, which is the soft tissue at the back of the roof of your mouth, plays a key role in viruses' ability to travel through the air from one person to another.
Scientists have released the "tree of life" for a staggering 2.3 million named species of animals, plants, fungi and microbes.
The deadly Ebola virus may be a lot more dangerous than we once thought. It seems as if genetic mutations called "escape variants" in Ebola block the ability of antibody-based treatments to ward of infection.
A new type of giant virus has been discovered-and now scientists are taking a closer look at it.
Most Americans aren't getting enough sleep and not only can that make you tired. It can also increase your risk for numerous health issues.
A 29-year-old British man made history. After receiving the polio vaccine as an infant, health officials discovered that it had somehow mutated to a virulent strain that had been living in his gut for over just about 30 years now.
It turns out that the Ebola virus may actually be able to survive in wastewater. Researchers have taken a closer look at Ebola-contaminated liquid waste and found that it could continue to survive over time.
There may be a better, longer-lasting flu vaccine in the works. Researchers have discovered a way to induce antibodies to fight a wide range of influenza subtypes-work that could one day eliminate the need for repeated seasonal flu shots.
It turns out that apes may have been infected by a HIV-like virus for millions of years.
Despite numerous treatments, new findings published in the journal EBioMedicine show that HIV is continuing to grow in some patients who are thought to be responding well to treatment.
Sea stars are dying all along the West Coast. Now, scientists have taken a closer look at the starfish in order to better understand its immune response and its ability to protect a diverse coastal ecosystem.
Could vaccines cause more virulent viruses? Researchers have conducted experiments with the herpesvirus that causes Marek's disease in poultry and have found that some vaccines could allow more-virulent versions of a virus to survive.
