This episode: Scientists engineered E. coli to seek and destroy pathogens!
(10 MB, 11 minutes)
A bacterium can sense pathogens in the body, swim toward them, and release a deadly biofilm-busting payload. This process is called pseudotaxis, and could be modified for many... Read More
Where humans travel, bacteria will follow. If people are in space for any amount of time, bacteria are sure to thrive there so it’s good to know that there are already researchers looking at how the environment within spaceships affects bacterial populations. Work done on planktonic colonies of ... Read More
This episode: "Selfish" jumping gene is actually helpful for its host plant's resistance to disease!
Infections caused by carbapenem-resistant enterobacteriaceae can be impossible to treat. A family of drug-resistant bacteria that experts say kills up to 50 percent of people infected is spreading in Chicago and elsewhere, prompting doctors and public health officials to step up efforts to prot...

Researchers at Columbia University are turning that optics-based imaging approach on its head, instead developing a chip based on integrated circuit technology that lets them not only electrochemically image bacteria, but listen in on them as well.

This is a picture of a bacterial community, taken by Eshel Ben-Jacob, who thinks bacteria are both the key to understanding complex biological systems and a source of incredible art. These bacteria, discovered by Ben-Jacob's research team, self-organize into intricate and beautiful systems.

One in every three bottlenose dolphin tested in the Indian River Lagoon on Florida's Atlantic coast has antibodies to a bacteria that can make them more vulnerable to other deadly infections, according to a new study.
The finding comes as researchers struggle to figure out what has caused a r... Read More
New research from the US has found a link between preterm births where the water sac around the baby breaks prematurely, and bacteria near where the walls of the sac are thinner.
The researchers, including Amy P. Murtha, associate professor of obstetrics and gynecology at Duke University Scho... Read More
The Rockefeller University's Luciano Marraffini is interested in understanding how bacteria evolve by incorporating DNA sequences from other bacteria or from the environment into their genomes. His research focuses on the mechanisms that control the traffic of DNA molecules between bacteria.
These bacteria-infecting viruses, phages for short, are the most abundant life-form on the planet, their number far exceeding that of stars in the universe. Trillions inhabit each of us.

In this post from my microbiology/education blog, I discuss a post on Boing Boing recently that used a video I had made of ice nucleation bacteria. Ice nucleation bacteria are very interesting of course, and I link to the Boing Boing post. In addition, I provide an additional video of students... Read More
Adorning your living room mantel with a petri dish full of germs normally wouldn’t sound appealing. But once you take a look at Zachary Copfer’s unique creations, you might be intrigued — if you’re not already running to the bathroom to wash your hands.
Copfer is a Cincinnati-based microbiolo... Read More
In this paper we describe the perspective of following the achievements in medicine, where gut microbiome transplants are proving to be a powerful method to overcome several gastrointestinal disorders and many other physiological problems, to possible solve diseases in plants. There is strong si... Read More

In addition to preventing unwanted pregnancies and the spread of sexually transmitted diseases, condoms may help good bacteria in the vagina flourish, a new study from China shows.
Sexually active women in the study who used condoms had larger colonies of beneficial microbes in their vaginas ... Read More
Certain types of papilloma virus might actually prevent cervical cancer, according to a new study by researchers from The University of Manchester. There are over 100 different types of human papilloma virus (HPV). Cervical cancer is known to be caused by infection with approximately 14 so-calle... Read More
Germaphobes, maybe you're on to something.
Sickness-causing bacteria and viruses can lurk on surfaces long after they're expelled in an infected person's sneeze or snot. Some can even stay on a surface for months, given the right conditions. While the ability of these microorganisms to actual... Read More

Bacteria can be friends and foes—causing infection and disease, but also helping us slim down and even combating acne. Now, a new study reveals that viruses have a dual nature as well. For the first time, researchers have shown that they can help our bodies fight off invading microbes.

There’s no question that variation in size and shape has conferred selective advantages over the course of evolutionary time. One of the most obvious examples is the long neck and legs of the giraffe, which allow it to snatch foliage that is unreachable by vertically challenged competitors. The ... Read More
