News: Researchers Look to Cows to Create Vaccine for HIV

A vaccine against HIV might prevent the disease that we can't seem to cure. Some HIV patients make antibodies that can take down the virus, much the way a vaccine might. But, scientists haven't been able to provoke that type of response in other people. However, in a process that might work in humans, a group of researchers has successfully generated antibodies in cows that neutralize multiple strains of HIV.

News: How Parental Choice Not to Vaccinate Kids Starts and Spreads Pertussis Outbreaks

It's not always easy to get to the root of an infection outbreak. Epidemiologists study infected people, contacts, and carefully examine where the infections happened and when. In the case of a 2012 outbreak of pertussis — whooping cough — in Oregon, scientists just published an analysis of how vaccination status affected when a child became infected during the outbreak.

News: To Stop Local Measles Outbreaks, International Travelers Need to Get Vaccinated — But Only 47% Do

In the worst measles outbreak in the state since 1990, the Minneapolis Department of Heath races to contain the spread of an infection believed to have originated from an infected traveler. Mistaken attitudes and unvaccinated travelers are creating a world of hurt and disease for Americans. A recent study found that more than half of eligible travelers from the US are electing to skip their pre-trip measles vaccine.

News: Dogs Could Be Spreading Antibiotic-Resistant Infections to Their Owners

Our canine best friends could spread our bacterial worst nightmare, according to a recent study. The problem with drug-resistant bacteria is well known. Overused, poorly used, and naturally adaptive bacteria clearly have us outnumbered. As science drives hard to find alternative drugs, therapies, and options to treat increasingly resistant infections, humans are treading water, hoping our drugs of last resort work until we figure out better strategies.

News: Scientists Show That the Earlier HIV Is Treated, the Better

HIV-infected people who are treated long-term with antiviral drugs may have no detectable virus in their body, but scientists know there are pools of the virus hiding there, awaiting the chance to emerge and wreak havoc again. Since scientists discovered these latent pools, they have been trying to figure out if the remaining HIV is the cause of or caused by increased activation of the immune system.

News: Frustrated by Acne? New Research Shows Skin Microbiome Makes a Difference

The squiggly guys in this article's cover image are Propionibacterium acnes. These bacteria live in low-oxygen conditions at the base of hair follicles all over your body. They mind their own business, eating cellular debris and sebum, the oily stuff secreted by sebaceous glands that help keep things moisturized. Everybody has P. acnes bacteria—which are commonly blamed for causing acne—but researchers took a bigger view and discovered P. acnes may also play a part in keeping your skin clear.
