Electrical impulses course through our heart and keep it beating. That's why a jolt from an automated external defibrillator can boost it back into action if the beating stops. But new research says there may be more to keeping a heart beating than just electrical impulses.

Our quest to find new antibiotics has taken a turn — a turn down the road, that is. A team of scientists from the University of Oklahoma is scooping up roadkill and searching for bacteria on them that might yield the world's next antibiotic.

Our quest to find novel compounds in nature that we can use against human diseases —a process called bioprospecting — has led a research team to a small frog found in India. From the skin slime of the colorful Hydrophylax bahuvistara, researchers reported finding a peptide — a small piece of protein — that can destroy many strains of human flu and can even protect mice against the flu.

In March, we wrote about the growing threat of yellow fever in Brazil. At the time, the disease had killed just over a 100 people. Unfortunately, the disease has only spread since then with many more people infected and more killed.

Despite the danger of this superbug due to its high resistance to most antibiotics, this information was only released to the public on Thursday. Thankfully, all ten babies survived and are currently healthy.

Acanthamoeba keratitis (AK), a rare eye infection caused by the Acanthamoeba ameba found in tap water, affects a few dozen people in the US every year. In some cases, it can have devastating effects, like what Irenie Ekkeshis has experienced; She was blinded by AK in her right eye due to a contaminated contact lens.

Texas has become only the latest state to face an unfortunate outbreak of mumps, but so far seems to be the hardest hit. On April 12, two days before the CDC's report was released, the Texas Department of State Health Services released a health advisory indicating this is the highest instance of mumps reported in 22 years.

Onshore, or on a boat, have you ever wondered what swims below in the dark water? Using standard equipment and a new process, marine scientists can now get a good look at what is swimming by—just by analyzing the water.

Warning: If you are eating and for some reason still decided to click on this article, turn around now. Maui, Hawaii health officials have reported finding at least six cases of angiostrongyliasis, a parasitic lungworm that infects humans. Colloquially, it's known as rat lungworm disease. And if you think that name is awful, just wait until you hear what it does to the human body.

Potbellies don't have to happen as we age, according to two studies done on twins published online in the International Journal of Obesity.

When it comes to global warming, most of us think of carbon dioxide emissions. While carbon dioxide is the most important greenhouse gas, carbon dioxide emissions have stayed constant for the last three years. On the other hand, methane, the second most important gas, has been steadily rising since 2007.

Usually, we think of vaccines as preventative, a shot we get to prevent the flu or some childhood disease like measles or mumps. But there are vaccines for other purposes, such as the ones studied by researchers from the Netherlands.

In the ongoing search to find better ways to use antibiotics, an extract made from maple syrup has some surprisingly important medical benefits.

How can bacteria that lives in the throat of 10%–35% of people—without causing an infection—cause life-threatening meningitis and sepsis in others?

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.

An advance in the race to stop birth defects caused by Zika-infected mothers has been made by a team of researchers from Rensselaer Polytechnic Institute in Troy, New York. They have identified the process Zika uses to gain entry into the placenta, and published their findings in the journal Biochemistry.

Growing populations and higher temperatures put pressure on world food supplies. Naturally occurring soil bacteria may save crops in drought-stressed areas, put more land into crop production, and produce more food.

Officials in Colorado are concerned as 61 cases of the mumps were reported so far this year, a significant increase in the prevalence of the contagious disease in the state.

Having a Clostridium difficile infection means stomach pains, diarrhea, fever, and loss of appetite, and if the symptoms weren't bad enough, the disease often reoccurs.

Nineteen days ago, several hundred people could have been exposed by a traveler with measles in Nova Scotia, Canada. The next day, someone flying from Minnesota to Nebraska may have spread the measles to other passengers. A couple weeks ago, it's possible that a man and his six-month old child spread the measles in several Seattle-based locations. Authorities are trying to locate persons who may have been in contact with these people. None of the persons with measles were vaccinated. Why?

Experts from the World Health Organization just expressed concern for the rising number of measles outbreaks across Europe. Despite a perfectly capable existing vaccine, "immunization coverage has dropped below the necessary threshold of 95%," causing the measles to spread throughout the European region.

When the mosquito that carries the malaria parasite (Plasmodium falciparum) bites someone, the parasite must travel to the liver where it undergoes part of its lifecycle before infecting red blood cells and spreading to its next host. Until now, the first step of how the parasite gets to the liver hasn't been clear.

Soy sauce is a sushi essential for most Americans and we don't often consider its exact origins whilst chowing down on that tuna roll.

According to Dr. Lindsey Fitzharris of The Chirurgeon's Apprentice, hospitals during the first half of the nineteenth century were known as "Houses of Death."

Bats are an important part of the US economy. They devour metric tons of bugs every night that would otherwise ravage crops and also be generally disgusting-looking and make you itchy. But they're in danger from a nasty fungal infection called white-nose syndrome, which has just popped up in Texas and has been spreading across the country.
