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.
Responding to the emergence of Zika in the US, researchers investigated what type of repellent works best to reduce your odds of a mosquito bite from Aedes aegypti, the mosquito species that spreads the Zika virus.

Exposed to hormones, pharmaceuticals, and other chemicals, the beautiful wild fish in Canada's Grand River have taken on some pretty odd characteristics—they're turning into females. A long-term study suggests using bacteria to manage polluted water could turn the tide for feminized fish.
Have you ever wondered what makes a healthy vagina? Bacteria play an important role in vaginal health. If you've ever had your vaginal microbiome—the bacterial community that lives in your vagina—wiped out by taking antibiotics, you probably are well aware of that.

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.
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.
Amidst reports of the newspaper industry struggling to survive, it's becoming more and more clear that people are increasingly turning to their smartphones for the news. In fact, a new study by the Pew Research Center has found that 85% of US adults check the news on mobile devices. Surprisingly, seniors constitute a sizable portion of this.
Dramatic new research may change the fate of the hundreds of people who wait for a kidney transplant every year. The study hinged on the ability to cure hepatitis C infections, a possibility that became a reality in 2014.
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.
Just like in the Spy Kids 3D movie, US soldiers may soon upgrade their mission planning from 2D to 3D. Welcome to the wonderful world of augmented reality, US Army.
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.
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.
From parents and other family members to friends and peers, personalities are built by environment. Though people are important in the development of our own individual personality, there are other, different influences, including what you choose to read. The books you take the time to enjoy can make you nicer and more understanding, or leave you overall unchanged.
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 there's even more ways to keep those bloodsucking bugs away.
We've all walked into a restaurant with the best of intentions only to order something absurd, like a cheese-injected burger topped with bacon on a brioche bun. It's delicious for the few minutes it takes to eat the thing, and then you're left with a bellyful of regret and an inability to directly look at the numbers on your scale. Turns out that getting yourself to make healthy choices isn't as hard as one might think.
