Bacteria are found in large numbers all over the human body where there is a channel to the outside world, for example in the gut, lungs, and surface of the skin. I’ve always thought that actually inside the human body was a bacteria-free environment unless an infection was raging so I was very ... Read More
Improvement in reforestation and agriculture is possible thanks to the work of scientists in the Center of Research and Advanced Studies (Cinvestav) who use different strains of fungi and bacteria to promote development and health in trees, which have enabled them to accelerate growth of differe...

In this blog post, I show a science-cartoon by the great "Beatrice the Biologist" that illustrates an important point in my freshman introductory cell and molecular biology course: no matter how tired we might be, we are incredibly busy on a cellular level! Beatrice is a fine artist who underst... Read More
An Auckland scientist has invented molecules that can attach themselves to any surface in a few minutes and modify every type of cell or virus. The potential for the technology is huge - from attacking cancer cells to protecting newborn babies. Read More
A decades long fight over cleaning up one of the nation's most contaminated riverbeds has posed a difficult question: how to safely remove enough toxic material from New Jersey's Passaic River to fill two MetLife Stadiums.
The federal government is moving forward with long-stalled efforts to ... Read More
A North Dakota company that discovered an antibody technology while trying to cure flocks of dying geese is using its research for a more warm and fuzzy purpose: saving puppies.
Early tests performed on about 50 puppies in seven U.S. states for Grand Forks-based Avianax have resulted in a 90 ... Read More
Dr. Tanya Parish and her TB Disco Team at IDRI use microbiology to develop new drugs for TB and improve the health of the world! Read More
Influenza viruses evolve rapidly, making it hard to develop protective vaccines against them. Despite a great deal of effort, scientists have found it difficult to forecast which way the virus’ evolution would take it. Now, thanks to improvements in our ability to study viruses and a new mathema... Read More
The Twivsters discuss how reverse transcriptase encoded in the human genome might produce DNA copies of RNA viruses in infected cells.
Food-poisoning outbreaks linked to disease-causing strains of the bacterium Escherichia coli are normally associated with tainted meat products. However, between 20-30% of these are caused by people eating contaminated vegetables, as was seen in the 2011 outbreak in Europe that caused 53 deaths.... Read More
The campaign is called "Kick Back Ebola." But the posters pack a punch.
Sierra Leone has reported over 700 suspected Ebola cases, more than any other country this year. To help stop the outbreak, health workers have put up Ebola awareness signs all over Sierra Leone's seaside capital of Freet... Read More
I have found that students become involved, energized, and enthusiastic when I give them opportunities to explore topics in my classes using their own creative approaches and interests. So this semester, in my Biology 111 course at the University of Puget Sound, I found that students explored f... Read More

This is a paper from the Geomicrobiology lab at the Jackson School of Geosciences at the University of Texas at Austin. It was recently published in a special issue of Geomicrobiology Journal focused on geomicrobiology of subsurface microorganisms in cave environments.
In this study we attemp... Read More
Teaming beneath Sweden's thawing permafrost is a previously undiscovered microbe known as methanongen (Candidatus Methanoflorens Stordalenmirensis). As its name suggests, the microbe does one thing really well: release methane into the atmosphere, presenting a feedback loop of gas production tha... Read More
A new device from Macquarie University can manipulate objects as small as 50 nanometers wide — about a thousandth of the width of a human hair and small enough to allow direct manipulation of a single viral capsule.

Babies who are exposed to both bacteria and allergens in the first year of life are less likely to develop asthma and allergies, a study finds.
It's the latest wrinkle in the hygiene hypothesis — the notion that exposure to bacteria trains the infant immune system to attack bad bugs and ignor... Read More
There’s nothing like an outbreak of Ebola virus disease to bring a small, struggling African nation to international notice. One week we couldn’t place it on a map; the next week, after Ebola virus disease strikes, we know the body count and the name of the capital and whether its airport has cl... Read More
