The Great Barrier Reef in Australia is the largest living system on the planet. Yet more than 90% of the reef is bleaching because of the loss of a tiny algae that lives within the coral.
The culprit probably wasn't what doctors were expecting when a 57-year-old man in Hong Kong came to the hospital. The patient was admitted to the intensive care unit in critical condition. A clue to the cause of the infection would lie in the man's profession—he was a butcher.
In the past, infection with human immunodeficiency virus (HIV) commonly led to dementia as the virus made its way to the brain. Even in effectively treated people, HIV can hide out and replicate in places like the brain, where it's tough to detect. That's why it's very concerning that half of all HIV-infected patients still report cognitive problems.
A robust appetite for imported foods is leading to increased disease outbreak in the US. Despite the locovore and slow food movements, America's demand for foreign foods is picking up. According to a study published in the journal of Emerging Infectious Diseases, demand for imported fresh fruits, vegetables, and seafoods has jumped in recent years.
Somewhere around 600–800 million people in the world are infected with whipworm (Trichuris trichiura), an infection they got from ingesting soil or water contaminated with feces of infected animals or people containing the parasite's eggs.
A tiny louse is responsible for decimating the citrus industry. Diaphorina citri, the louse in question, better known as the Asian citrus psyllid, harbors and spreads the "Candidatus Liberibacter asiaticus" bacteria that causes citrus greening disease.
Although their effectiveness is waning, antibiotics remain a front-line defense against many infections. However, new science reveals using the wrong antibiotic for an infection could makes things much worse.
As fun as it is to see Fido's face light up when you feed him table scraps, American dogs are getting fat. The good news is that research is homing in on nutritional strategies to boost canine capabilities to maintain a healthy weight.
Lighthouses and signal fires may have been the first social media. Without the ability to share language, a distant light meant "humans here." A new study from the University of California, San Diego, finds that bacteria can also send out a universal sign to attract the attention of their own, and other bacterial species.
We all know you are what you eat—or so the expression goes—but it's good to remember that what you are (at least intestinally) is mainly bacteria. A new study has shown that what you eat, and how your gut microbiome reacts to that food, might be a key player in your risk of developing a certain type of colon cancer—and changing your diet can help decrease your risk.
Responding to the rapid emergence of dangerous pathogens around the world, a new initiative to prevent or contain pandemics was announced in Davos, Switzerland, yesterday. If you ever worried that a highly contagious pathogen could take down your community, or the country, this news is for you.
After California college student Luis Ortiz blacked out and was taken to the hospital in 2015, doctors were startled to discover the reason his brain was swelling—a one-centimeter long, wriggling tapeworm living within a ventricle in the middle of his brain.
Cholera may be rare in the US, but cases of the disease have increased worldwide since 2005, particularly in Africa, southeast Asia, and Haiti. An estimated 3 to 5 million people are infected, and more than 100,000 die from the disease globally each year, mostly from dehydration.
Using mathematical modeling, researchers suggest weather and warming created the "perfect storm" that drove the Zika outbreak in 2016.
New weapons are needed to combat antibiotic-resistant bacteria. Instead of drugs, scientists have discovered in an animal study that they may be able to harness vampire bacteria to vanquish pneumonia.
With the height of the flu season ahead, there are some good reasons to keep a flu vaccination in mind.
A friend of mine is a classically trained chef, and she often invites me over to her house to eat whatever goodies she has concocted. A few years ago I asked her the cliché question that every chef is sick of answering: "What's your favorite food?"
Eating healthy poses a challenge nowadays with so many options that taste great but aren't really good for you. Nutritionists have made it their life's work to understand what actually does a body good. Here's how you can follow their example.
Osteoarthritis can affect every gender and at any age but it commonly occurs in women than in men. In America there are approximately 27 million Americans aged over 25 who live with osteoarthritis.
I'm sure that there are plenty of people out there who have no idea what a plague doctor is/was, so I'll start with an explanation.
A Steampunk's Guide to Sex was the subject of a recent successful Kickstarter campaign, and I now hold the finished book in my hands. As such, I can say (mostly) unreservedly that you should buy this book. Allow me to tell you why, before I get into the nitty-gritty about the book itself. Sex is something of an odd topic in America because it's perfectly legal, and yet taboo. Unlike things that are illegal and not taboo, like drug use, murder, theft, etc. What this means is that children can ...
Google is an incredibly useful database of indexed websites, but querying Google doesn't search for what you type literally. The algorithms behind Google's searches can lead to a lot of irrelevant results. Still, with the right operators, we can be more exact while searching for information that's time-sensitive or difficult to find.
As the fish farming industry struggles to become more environmentally friendly, it just gained another problem. Fish food loaded with antibiotic-resistant genes.
The bacteria in our gut — a community called the gut microbiome — have been in the spotlight a lot lately. What we're learning about how our intestinal bacteria adapt and grow with our bodies could help athletes perform better, according to researchers starting a company focused on creating probiotics that mimic athletes' microbiomes.
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.
Blowing dust and fungal spores are creating a public health problem that could be just a slice of what's to come with climate change.
Whether or not a microbe is successful at establishing an infection depends both on the microbe and the host. Scientists from Duke found that a single DNA change can allow Salmonella typhi, the bacteria that causes typhoid fever, to invade cells. That single genetic variation increased the amount of cholesterol on cell membranes that Salmonella and other bacteria use as a docking station to attach to a cell to invade it. They also found that common cholesterol-lowering drugs protected zebrafi...
So cute, so furry, and so chock full of parasites. While raccoons are fun to watch, they are neither friendly nor clean — and they can make you sick in more ways than one.
Tell the truth. The bat picture creeps you out. You are not alone. But in reality, bats truly are some of our best friends. They gobble thousands of disease-spreading bugs a night. But they also carry viruses that can be deadly to humans. So, bats — friend or foe?
There is a reason the Amanita phalloides mushroom is called the "Death Cap." It can kill you. Mushrooms are a type of fungi, an organism that produces thread-like mycelia that often produce spores. Spores allow the fungi to reproduce. Molds, lichens, and yeast are all fungi, but the most visible fungi are mushrooms. Some fungi are delicious, but others can cause disease or, and still others, like Penicillium, can cure it.
Bed bugs are brown and creepy. Could you spot one in your hotel room? A new study reveals most people are freaked out by bed bugs, but only about 35% could identify one.
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.
If you have encountered bed bugs lately, you are not alone. While the pesticides used to fight these pests are losing effectiveness, a fungus shows promise in knocking the bugs out of beds everywhere.
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.
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?
You can get eggs and high-quality compost from backyard chickens—but you can also get Salmonella.
Add antibiotics to the possible list of culprits responsible for honeybee decline around the world. While it may come as a surprise, antibiotics are commonly mixed into feed used by commercial beekeepers to maintain their hives. In a recent study published in PLOS Biology, researchers from the University of Texas at Austin found antibiotics used to treat honeybees may be a contributing factor in individual bee death and colony collapse.
As researchers learn more and more about our intestinal bacteria—also called the gut microbiome—we're finding out that these microbes aren't just influencing our health and wellness, they're a useful tool for improving it, too.
To much of the United States, Zika seems like a tropical disease that causes horrible problems in other countries but is nothing to be worried about stateside. It may make you rethink your beach vacation abroad, but not much more than that. However, if you live in Florida or Texas, the possibility of getting a Zika infection where you live is real — and local outbreaks are more and more a possibility.
