On the list of substances you really don’t want to mess with, elemental mercury is pretty high up. Inhalation or absorption of the volatile metal can quickly lead to irreversible poisoning. Unfortunately, Hg is also a hallmark of industrial society.....Mercury-resistant bacteria carry a collecti... Read More
Quorum sensing is one of the most amazing things about bacteria. More and more research is focusing on potential quorum sensing applications in biomedicine and many other fields of life sciences.
This is a video that I made about QS for a competition in my University. No previous science bac... Read More

Hello TWiM team,
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
The Foldscope is a fully functional microscope that can be laser- or die-cut out of paper for around 50 cents.
This bookmark-sized microscope can be assembled in minutes, includes no mechanical moving parts, packs in a flat configuration, is extremely rugged and can be incinerated after to s... Read More
Vibrio cholerae was isolated in the capital city Kathmandu , where as it causes cholerae endemic in certain remote parts in the country every year .

Creating synthetic organisms with specially-tailored genomes is a long way off, but the first synthetic eukaryotic chromosome is a big step forward.
Humans have been using what they know about the biological world to make stuff for centuries—from beer to antibiotics. But, what if you could ma... Read More
A rare, recently discovered microbe that survives on very little to eat has been found in two places on Earth: spacecraft clean rooms in Florida and South America.
Microbiologists often do thorough surveys of bacteria and other microbes in spacecraft clean rooms. Fewer microbes live there tha... Read More
Virulent, drug-resistant forms of E. coli that have recently spread around the world emerged from a single strain of the bacteria, not many different strains, as has been widely believed.
The strain—which causes millions of urinary, kidney and bloodstream infections a year—could have a far gr... Read More
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

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
The latest version is called H6N1, and represents the first time that this strain of bird flu has jumped from birds to people.
Flu researchers are especially wary of birds, from wild avian species like migrating geese to run-of-the-mill chickens at local poultry markets. They harbor a series ... Read More
Hi Dr.s R&D,
I thought you might be interested in this news article about aquaculture in Hong Kong. Perhaps it's time for another fish parasite episode? I love the podcast, keep up the great work.

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
In this blog entry, I explore how students can use their creativity to learn microbiology in innovative and often artistic ways. It makes learning more personal! Read More
As any new parent knows, infants are notoriously susceptible to bacterial infections. A study now suggests that the body engineers this vulnerability deliberately, allowing beneficial microbes to colonize the baby’s gut, skin, mouth and lungs. Learning to manipulate this system could lead to tre... Read More
Ancient viruses from Neanderthals have been found in modern human DNA by researchers at Oxford University and Plymouth University.
The researchers compared genetic data from fossils of Neanderthals and another group of ancient human ancestors called Denisovans to data from modern-day cancer p... Read More
