Viruses act like self-packing suitcases

Researchers at the University of Leeds have identified a crucial stage in the lifecycle of simple viruses like polio and the common cold that could open a new front in the war on viral disease.

The team are the first to observe at a single-molecule level how the genetic material (genome) that... Read More

10 Surprising Things That Bacteria Like to Eat

You've probably heard of necrotizing fasciitis, also known as flesh-eating bacteria. But bacteria do not actually eat human flesh. They're actually trying to gobble up something a lot weirder. Here are ten of the stranger things bacteria naturally (and unnaturally) eat. You'll never look at dirt... Read More

Superbug MRSA Identified in US Wastewater Treatment Plants

A team led by researchers at the University of Maryland School of Public Health has found that the "superbug" methicillin-resistant Staphylococcus aureus (MRSA) is prevalent at several U.S. wastewater treatment plants (WWTPs). MRSA is well known for causing difficult-to-treat and potentially fat... Read More

Meet the Bacteria That Produces Pure Gold

Scientists have discovered bacteria that eats toxic material and, well, poops pure gold. This microbial magician, named Cupriavidus metallidurans, when placed in a minilab full of gold chloride, a nasty toxin, gobbled up the poison and, in about a week, processed it out as 24-karat nuggets of th...

Germ killer in hand soap may weaken muscles

A chemical widely used in soaps, toothpaste, and toys weakens muscles in mice. Triclosan, an antibacterial chemical, hinders muscle contractions at a cellular level, slows swimming in fish, and reduces muscular strength in mice, according to researchers at the University of California, Davis, an...

Dennis writes:


Dear Vincent,


I am glad you had a chance to get a glimpse of the BSL4 world. You might remember that I have been trying for 1 1/2 years to get you to see the Galveston National Laboratory, a facility with an actual ACTIVE program and a number of... Read More

Microbiologists Will Watch As Bacteria Take Over This Hospital

We often think of the world around us as sterile and static, especially when we are in a hospital. In reality, every surface on earth is literally teeming with millions of bacteria.

Jack Gilbert, a microbiologist from the University of Chicago, has spent his career investigating these invisib... Read More

Giant Viruses Are Ancient Living Organisms

A new study of giant viruses supports the idea that viruses are ancient living organisms and not inanimate molecular remnants run amok, as some scientists have argued. The study may reshape the universal family tree, adding a fourth major branch to the three that most scientists agree represent ... Read More

Missing Carl Woese---RIP!

I comment a bit, as an educator, about the loss of Carl Woese. Not only the importance of his discoveries, but how he went about his work, remains of great value. Read More

Do Cranberries Prevent UTIs?

There is a long history of anecdotal evidence to suggest that cranberries and other alternative therapies to long-term antibiotics can prevent recurrent urinary tract infections but are they really as effective as antibiotics or even a viable alternative for people who do not want to take antibi...

Scientists Discover New Type of Virus Responsible for a Devastating Disease in Snakes

A mysterious condition called Inclusion Body Disease (IBD) strikes captive boa constrictors and pythons, causing bizarre behavioral changes and eventually death. Scientists investigating an outbreak of IBD among snakes at the Steinhart Aquarium in San Francisco report they may well have found a ... Read More

HIV Infection and Cardiovascular Health

Since the introduction of highly active antiretroviral therapy in the mid-1990s, HIV infection has evolved from a near-certain death sentence to a manageable, chronic disease. Still, little is known about the long-term effects of HIV on human health. Two studies being presented today on cardiova... Read More

Eating Volatile Garbage: Bacteria for Bioremediation

There is much in the way of microbial activity that is taking place in one of the world’s most poisonous dumps, which turns out to be cleaning up the place.

Take the 150-foot-high garbage dump in Colombia, South America. Soon it may have life as a public park thanks to work from researchers ... Read More

Yeast cells that share food have a survival edge over their freeloading neighbors — particularly when there is bacterial competition.

Many species exhibit cooperative survival strategies — for example, sharing food or alerting other individuals when a predator is nearby. However, there are almost always freeloaders in the population who will take advantage of cooperators. This can be seen even among microbes such as yeast, whe... Read More
