Urinary tract infections (UTIs) drive over eight million people to seek medical attention every year. Almost all — as many as 90% — of those infections are caused by Escherichia coli. Copper can kill bacteria, but E. coli has found a way to capture the copper, preventing its antibacterial action. Now, researchers have found that, in a cruel irony, the bacteria use the copper it grabs as a nutrient to feed its growth.
How would you feel if the stethoscope used by your doctor to listen to your heart and lungs was teeming with potentially unfriendly bacteria?
For as long as 14,000 years, the First Nations people of the Heitsuk Nation have made their home along the Central Coast of the Canadian province of British Columbia. Among the territory's inlets, islands, rivers, and valleys lie a clay deposit on the north side of Kisameet Bay, near King Island. For as long as most can remember, the tribe has used the clay as medicine. Now science says microbes that live in that clay may have important antibacterial properties.
Rising on the world stage, dengue fever is transmitted by mosquitoes — and apparently air travel too.
A 6,000-year-old forest inhabitant awakens to find life in the forest around it in crisis. Plants, trees, animals, and birds are moving north to escape increasingly heated air, even as mass extinctions take place around the world. The inhabitant stirs and remembers it has lived this before and knows what to do.
Wherever there are people, the party is sure to follow. Well, a party of microbes, at least. That is what scientists at NASA's Jet Propulsion Laboratory have found after a 30-day microbial observation of the inflatable lunar/Mars analog habitat (IMAH).
Growing evidence suggests that neurodegenerative diseases like Parkinson's may develop in part due to environmental factors, including infections that can cause inflammation in the nervous system. New research from investigators from Jude Children's Research Hospital and Thomas Jefferson University has strengthened that connection.
That soil under your feet is not just dirt. It is teeming with life that may not change as fast as we would like when challenged by global warming.

Even though the Ebola virus was discovered as recently as 1976, over 30,000 people have been infected since, and half have died a horrible death. Since there's no way to cure the infection, the world desperately needs a way to prevent it — and the five similar viruses in its family, the ebolaviruses.

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.
With a predicated increase in the number of Lyme disease cases in the coming spring season, new research endorses the use of bait boxes to control ticks on the rodents that serve as their hosts.
If you want to appreciate the value of microbes, look no further than a chunk of cheese. Because cheese roughly traces back to the Neolithic Era, we might say the earliest cheesemakers were the first humans to manipulate microbes—without even knowing it. Now, thanks to microbiologists and the long tradition of cheesemaking, we know a lot more about the microbes that make our favorite types of cheese possible.
The rate of preterm birth has been increasing in the United States for unknown reasons, causing increased health risks for infants born too soon. But researchers may have found a signal that could help doctors plan ahead for, or even prevent, early birth with a simple swab of the vagina and cervix during pregnancy.
The pathogen referred to as a "nightmare bacteria" is quietly adapting and spreading faster than anticipated.
Transmitted by a sandfly one-third the size of a mosquito, parasitic Leishmania protozoa are responsible for a flesh-destroying disease that kills an estimated 20,000 people per year. Two new studies offer understanding of how the parasite provides immunity through persistence and why some people suffer more virulent forms of the disease.
Findings from a mouse study suggest that the Zika virus infection may have serious reproductive consequences for men.

There are many, many home remedies out there for relieving itchy mosquito bites. Everything from mud to banana peels and basil leaves to Alka-Seltzer tablets can help curb the itch. But before you even have to resort to any of those methods, you should be thinking about prevention. Wearing white clothing can help to keep mosquitoes aways from your skin, and there are many plants that will help mask your mosquito-attracting smell. But there's even more ways to keep those bloodsucking bugs away.

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.
How can a drug used to treat cancer be effective against viruses, too? The answer lies in the drug's shared target — specifically, cellular components that control the activity of genes. A new research study showed that one such type of drug, histone methyltransferase inhibitors used in cancer clinical trials, has activity against herpes simplex virus, too.
