Malaria is a massive worldwide health problem. The Centers for Disease Control and Prevention estimate that 212 million cases of malaria occurred worldwide in 2015 and 429,000 of the infected people died. Once infected, the parasite multiplies in human red blood cells until i ...more

Deadly rat lungworm parasites have found their way into Florida. The parasitic worm relies on snails and rats to complete its life cycle, but don't let this nematode's name fool you. This worm can cause meningitis and death in humans who inadvertently consume snails, frogs, or ...more

On June 11, 2016, an Arizona woman died from what appeared to be several infections, including pneumonia. She likely caught at least one of these from her dog. The Centers for Disease Control and Prevention (CDC) were involved in the investigation into events leading up to he ...more

Most of us have already had an encounter with the Epstein-Barr virus, or EBV, for short. As part of the herpes family, it's one of the most common disease-causing viruses in humans. We get the disease with (or without) some nasty symptoms, then we recover. However, EBV stays i ...more

By looking for the mechanism that allows influenza A to invade lung cells, scientists also discovered a treatment that might block the virus from taking hold there. An infection of the lungs is called pneumonia, which is caused by bacteria, viruses, and fungi that target alve ...more

The evidence is mounting and is becoming indisputable: Gut bacteria play a role in strokes and heart attacks. The link may seem a little far-fetched, but cardiovascular disease may have less to do with what we eat and more to do with what chemicals gut bacteria make from the f ...more

Frosty the Snowman is a fairy tale they say, but this microscopic snowman is very real and just broke the record for the world's smallest snowman. (Though, it's not Guinness-official yet.) Created by the Western University Nanofabrication Facility in London, Ontario, this tin ...more

People who have heart disease get shingles more often than others, and the reason has eluded scientists since they first discovered the link. A new study has found a connection, and it lies in a defective white cell with a sweet tooth. Shingles is a reactivation of the same v ...more

The problem with HIV is that it attacks and kills the very cells of the immune system that are supposed to protect us from infections — white blood cells. But a new technique, developed by scientists at The Scripps Research Institute (TSRI) in La Jolla, California, offers a di ...more

As researchers from Yale searched our environment for compounds to aid in the battle against drug-resistant bacteria, they got an unlikely assist from ticks. Ticks are best known for being the nasty bloodsuckers that spread dangerous infections like Lyme disease, the Powassan ...more

We fight cancer in a variety of ways, but no matter whether drugs, biologics, or our immune cells are part of the battle, they can do a better job fighting back cancer if we can help them find the tumors. Scientists from the University of Rochester Medical Center (URMC) have ...more

A rose by any other name may smell as sweet, but one annoying invasive weed may hold the answer to treating the superbug MRSA. Researchers from Emory University have found that the red berries of the Brazilian peppertree contain a compound that turns off a gene vital to the dr ...more

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. T ...more

Over 1.2 million people in the US are infected with human immunodeficiency virus (HIV)—and one out of eight of them don't know it. Even after decades of intense research into the virus, there's still no cure for it. One of the big problems is that the virus hides out in certai ...more

The number of households in the US that go hungry because they lack money for food hit a high of almost 15% in 2011. While that number continues to decline, nearly 13% of American households still go hungry. Malnutrition — either from not eating enough or not getting enough n ...more

Antibiotics are one of our main weapons against infections. The problem is that many bacteria are becoming resistant to most of the antibiotics we use to treat them, and those 'superbugs' have created an urgent threat to our global health. A research group found a new way to h ...more

You might feel the bite, you might not, but an infected mosquito has injected you with a parasite named Plasmodium falciparum, a single-cell protozoa that quickly takes up residence in your body. You don't feel a thing as the parasite infects your liver and begins to multiply ...more

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, th ...more

I've never had a black eye, but I was in a car accident that turned my entire ear dark purple a few years ago. Believe me; it was enough to get more than a few funny looks. Walking around with bruises is never fun, and it's even worse when they're on your face or neck. A blac ...more

Once we recover from the respiratory infection pneumonia, our lungs are better equipped to deal with the next infection — thanks to some special cells that take up residence there. New research led by JP Mizgerd of the Boston University School of Medicine, shows that lung tis ...more

In each day of our life, we see inflammation. We see it during sore throats and abscess formations in our bodies, and even slight tooth pain is a form of inflammation. Sometimes it's good when it fights to protect us from invading organisms, but sometimes it becomes bad when i ...more

Heart disease is the leading cause of death of men and women in the US. Over half a million Americans die from it annually. Atherosclerosis — a build up of plaque in the arteries — is a common feature of heart disease and can be caused by smoking, fats and cholesterol in the b ...more

As if the swollen, painful joints of rheumatoid arthritis weren't enough, the disease is the result of our immune system turning against cells of our own body. Ever since this realization, scientists have worked to find the trigger that sets the immune system off. Scientists b ...more

Fasting—or the practice of regularly abstaining from ingesting anything except water—is a pretty drastic move. I tried to fast for two days and made it to the 12-hour mark, which is when I broke down and ate a quart of ice cream. However, I may have to try it again, since "sh ...more

Natural remedies used through the ages abound, especially in Asian medicine. The willow-leaved justicia plant, found throughout Southeast Asia, has traditionally been used to treat arthritis, but scientists have just discovered it contains an anti-HIVcompound more potent than ...more

In the US, ticks can spread several pathogens in one bite. A new test offers physicians the ability to identify what infections ticks are carrying and can detect if one of the pathogens could be the spreading Powassan virus. Ixodes scapularis, better known as the black-legged ...more

Where in the world did it come from? All of a sudden, one day, someone had an infection with flesh-eating bacteria. It captured headlines and worldwide attention because it was such a severe, strange, uncontrollable, and really disgusting condition. We still might not know wh ...more

Not all bacteria in the eyes cause infection. A group of researchers from the National Eye Institue has shown that not only is there a population of bacteria on the eyes that reside there but they perform an important function. They help activate the immune system to get rid o ...more
