Plants all around us capture sunlight every day and convert it to energy, making them a model of solar energy production. And while the energy they make may serve the needs of a plant, the process isn't efficient enough to generate power on a larger scale. So, scientists from the University of California found a way to treat bacteria with chemicals that turned them into photosynthesis machines, capable of generating products we can convert into food, fuels, and plastics.
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.
Infections with group A streptococcus, like Streptococcus pyogenes, claim over a half million lives a year globally, with about 163,000 due to invasive strep infections, like flesh-eating necrotizing fasciitis and streptococcal toxic shock syndrome.
The intestinal parasite Cyclospora cayetanensis has a dramatically increased infection rate this summer, and the source is still unknown, the CDC advised today. 2017 is a good year for Cyclospora looking for homes to start their families and a bad year for those of us who don't like food-stealing tenants living in our bodies.
Four million Americans misused prescription opioid painkillers in 2014. Those who do are 40 times more likely to inject heroin or other drugs than other people. Now, the Centers for Disease Control and Prevention (CDC) are blaming that misuse for a 12-fold increase in endocarditis, an infection of the heart valves.
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.
There has been an outbreak of syphilis in Oklahoma County with 75 confirmed cases connected by a social network driven by drug use and sex.
We can add one more health effect of our gut bacteria to the growing list. Researchers from the UK have just reported that the gut microbiota plays a role, both directly and indirectly, on the toxicity and efficacy of chemotherapy. Their findings are published online in the journal Nature Reviews Gastroenterology & Hepatology.
Norovirus outbreaks occur all year long, but peak in the winter months, which means we are in the middle of norovirus season. But there's still time to protect yourself from the highly infectious bug.
The Centers for Disease Control and Prevention (CDC) just reported some upsettingly high numbers of human papillomavirus (HPV) in adults. In data retrieved from 2013–2014, 22.7% of US adults in the 18–59 range were found to have the types of high-risk genital HPV that cause certain cancers.
Since the 1960s, bacteria have been hopping a ride into space on space vehicles and astronauts, and have been cultivated within experiments on space shuttles and the International Space Station (ISS). The extreme growing conditions and the low gravity environment on the Earth-orbiting vehicles offers a stable research platform for looking at bacteria in a different light.
As unappealing as it sounds, transplants with fecal material from healthy donors help treat tough Clostridium difficile gastrointestinal infections. Researchers credit the treatment's success to its ability to restore a healthy bacterial balance to the bowels, and new research has shown that the transplanted bacteria doesn't just do its job and leave. The good fecal bacteria and its benefits can persist for years.
When the climate changes, so do all the things that rely on the climate, including people, plants, and pathogens. A European study recently took a broad look at what kind of microorganisms are most likely to be affected as climate change heats, cools, dries, and wets the world around us.
Bacteria, viruses and other germs sometimes set off the immune system to overreact, producing a severe condition called sepsis. Sepsis is so dangerous that it is the leading cause of death of children across the world, killing a million kids every year, mostly in developing countries. Probiotic bacteria might be able to prevent sepsis and infections, but no large research studies have been done to find out whether that actually works. Until now.
Love is the spice of life — it is also the microbes that couples share through sickness and in health, through the bathroom and in a hallway.
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.
Foodborne infections often occur through the contamination of equipment, food-prep tools, and unsanitary surfaces. A recent report from the Centers for Disease Control and Prevention (CDC) reminds us that breast pump parts are part of the food-delivery chain — and they can become contaminated too.
The community of bacteria that lives in our gut has a lot to tell us. It can give clues to what we eat, the environment we live in, and diseases and disorders we may have. Now, scientists have linked these bacterial species to how we feel. A new research study found an association between women's gut bacteria and their emotions.
Sex makes the world go 'round, and when it does, so does gonorrhea. Finally some good news on the growing menace of drug-resistant gonorrhea — a large, long-term study shows a vaccine may work in reducing the incidence of an increasingly dangerous infection.
Add breathing in your house as another possible danger to your health. If your home is sick, it's possible you could get sick too.
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.
If you know that ticks spread Lyme disease, you may already know you might also catch a bunch of other infections from them. One of the lesser-known diseases spread by ticks is infection with the bacterium Anaplasma phagocytophilium, called anaplasmosis.
Dengue fever is a danger to anyone living or visiting tropical or subtropical regions. It can be hard to detect the infection in its earliest and most treatable phase, especially in children. Luckily, new research highlights better techniques for triaging the disease in infected children with more severe symptoms, potentially saving lives.
Could your fever, body aches, cough, and sore throat be the flu? Soon, finding out may not involve a trip to the doctor.
As headlines focus on melting glaciers and rising water levels caused by global warming, climate change is quietly taking its toll on the nearly invisible occupants of this planet, the microbes.
Lyme is a growing threat as we move into warmer weather in the US. Researchers have said this year could be one of the worst for this tick-borne disease, as a skyrocketing mouse population and warmer temperatures increase the risk.
Termite poop and biofuels — what's the connection? New research into termites' intestinal comings and goings describes a process that may speed the development and lower the cost of fuels made from plant matter.
Cholera is rapidly spreading in Mozambique, with over 1,200 people infected. Since the outset of 2017, cholera has spread from the capital city of Maputo (pictured above) to three of its ten provinces. Health officials report other areas in the country are seeing case counts rise, and two deaths have been logged so far.
Have you ever had the stomach flu, aka the 24-hour flu? Well, chances are high that you never had influenza, but an intestinal infection called gastroenteritis.
Marijuana is legal to use for medical purposes in 28 states and the District of Columbia, but the quick development of this new industry could have left some regulation issues in the lurch.
As drug-resistant bacteria become more commonplace, researchers are looking for new antibacterial strategies to disrupt disease-causing microbes. Some scientists are working to create new drugs, while others are trying out drug combinations. Another group, however, are ditching pharmaceuticals altogether and experimenting with non-drug alternatives.
New research suggests the bacteria that causes listeriosis may be a bigger threat in early pregnancy than previously thought. Usually considered a danger to late pregnancy, scientists suggest early undiagnosed miscarriages could be caused, in some cases, by infection with Listeria.
Every year, 100-200 people in the US contract leptospirosis, but usually 50% of the cases occur in Hawaii where outdoor adventurers are exposed to Leptospira bacteria found in freshwater ponds, waterfalls, streams, and mud. That's why it's so alarming that two people in the Bronx have been diagnosed with the disease and a 30-year-old man has died from it.
You know the signs—sneezing, fever, nagging cough, no energy, no appetite. It's the flu, but this time, it's your dog who's down and out. Yes, dogs get the flu, too. However, a team from the University of Rochester Medical Center and their collaborators have developed a new vaccine that may make the doggy flu a thing of the past.
It hasn't even been eight years since Candida auris was discovered—cultured and identified from the ear canal of a patient in Japan—and now it's drug-resistant, setting up residence in hospitals, killing patients, and wreaking havoc across the globe.
Transmitted by ticks, Lyme disease is a serious infection that is probably headed your way. A recent study confirms the pathogen that causes Lyme disease is now established in nine national parks in the East, including Acadia and Shenandoah National Parks.
A new study casts real suspicion on the possibility of life on Mars. Why? It seems the surface of the planet may be downright uninhabitable for microbial life as we know it.
A disease called "citrus greening" has devastated and permanently altered citrus production in the United States, but a vaccine that could protect orange trees may be part of a winning strategy to beat the bacteria that is killing the trees.
Potbellies don't have to happen as we age, according to two studies done on twins published online in the International Journal of Obesity.
Arsenic occurs naturally in the environment, but it is also one of the most commonly found heavy metals in wastewater, deposited there by inappropriate disposal and arsenical pesticides, for example.
