Virtual bees help to unravel microbial and other causes of colony decline

What effect does the varroa mite, and the viruses it transmits, have on bee colonies? To find out, scientists have developed a new computer model to that simulates a honey bee colony over the course of several years.
Shown in the video on this page, the BEEHAVE model was c0-funded by BBSRC and... Read More

Tamoxifen drug appears to kill fungus associated with deadly brain infection

The drug tamoxifen appears to kill a fungus associated with a deadly brain infection that afflicts HIV/AIDS patients, according to a University of Rochester study published online today by mBio, the journal of the American Society for Microbiology.

Salmonella grown on Salmonella-Shigella (S-S) Agar

The following picture shows the isolated black colonies of Salmonella on Salmonella-Shigella (S-S) Agar. S-S Agar is used as a selective and differential medium for the isolation of Salmonella and some Shigella species. The inclusion of bile salts is to inhibit gram-positive organisms. Ferric ci...

Exploring The Invisible Universe That Lives On Us — And In Us (cool NPR animated video)

The next time you look in a mirror, think about this: In many ways you're more microbe than human. There are 10 times more cells from microorganisms like bacteria and fungi in and on our bodies than there are human cells.

Scientists increasingly think that these microorganisms have a huge inf... Read More

Hijacking bacteria's natural defences to trap and reveal pathogens

Bad bacteria could soon have no place left to hide, thanks to new materials that turn the cell’s own defences against them.

Scientists at The University of Nottingham and GSK Consumer Healthcare have developed a technique that could locate the potential source of an infection by hijacking the... Read More

TWiV 301: Marine viruses and insect defense

At the International Congress of Virology in Montreal, Vincent speaks with Carla and Curtis about their work on RNA interference and antiviral defense in fruit flies, and viruses in the sea, the greatest biodiversity on Earth.

Arctic bacteria gene swap to detoxify mercury

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

New flu virus found in Peruvian bats

A brand new flu virus has been found in Peruvian bats, according to a new study from researchers at the Centers for Disease Control and Prevention.

The virus, called A/bat/Peru/10, belongs to a family of flu virusesknown as influenza A, which mainly infect birds, but can also infect other ani... Read More

Should We Destroy Our Last Living Samples of the Virus That Causes Smallpox?

This month the World Health Organization (WHO) will meet to decide whether or not to destroy the last living strains of the variola virus, which causes smallpox. Since the WHO declared the disease eradicated in 1979, the scientific community has debated whether or not to destroy live virus sampl... Read More

Will Antibiotics Be There When You Need Them? Get Smart

Just in time for “Get Smart about Antibiotics Week,” I had a refreshing experience recently, working in a different rural hospital. Over that week, I didn’t see one patient with “superbugs” other than the occasional MRSA. No one had the now scarier Gram negative bugs known as ESBLs (extended spe... Read More

New Springtime Flu Strain Going Around New York

Thought you only had to deal with allergies these days? Well, maybe you've noticed some friends or work colleagues calling in sick lately—that may be because there's another flu strain making the rounds.

According to the Centers for Disease Control, influenza B is accounting for 55% of all vi... Read More

New research shows how pathogenic E. coli O157:H7 binds to fresh vegetables

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

Talking Bacteria

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

First Case of New Bird Flu Identified in Human Patient

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

Paint a virus to death

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

What Gut Bacteria Might Have To Do With Colorectal Cancer Risk

While genetics likely play a role in some instances of colorectal cancer, a new study in mice suggests gut bacteria could also influence development of intestinal tumors. Researchers from the Icahn School of Medicine at Mount Sinai found that giving antibiotics to mice to disrupt their microbial... Read More

On a Cellular Level, We Are ALL Overachievers!

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

Rare New Microbe Found in Two Distant NASA Clean Rooms

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
