The Hidden Life of Microscopic Fungi

Most mushrooms actually do not produce the visible fruiting bodies known to us as boletus, champignons, or toadstools. Many fungal species are the familiar “mold” and other unappetizing films, or are completely unknown to us. Here, you can discover some of the remarkable shapes and lifestyles of... Read More

Virus-derived particles target blood cancer

Ottawa researchers have developed unique virus-derived particles that can kill human blood cancer cells in the laboratory and eradicate the disease in mice with few side effects. The study is published in Blood Cancer Journal by co-senior authors Drs. David Conrad and John Bell of the Ottawa Hos... Read More

High-angle helix helps bacteria swim

t’s counterintuitive but true: Some microorganisms that use flagella for locomotion are able to swim faster in gel-like fluids such as mucus. Research engineers at Brown University have figured out why. It's the angle of the coil that matters. Findings are reported in Physical Review Letters.

MRSA strain in humans originally came from cattle

A strain of bacteria that causes skin and soft tissue infections in humans originally came from cattle, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology. The researchers who conducted the genetic analysis of strains of Staphyl... Read More

Crowd-funding: Help Support Research into Using Bacteria to Clean Up the Environment

This research team is using directed evolution to develop strains of Pseudomonas aeruginosa that can chelate and remove heavy metal contaminants from the environment. They're trying to raise money directly from the public to support their research. If you want to participate in this project, at ... Read More

Canine distemper in rare Amur tigers poses "significant risk to survival"

Endangered Amur tigers (also called Siberian tigers) face challenges from poaching, decimation of their prey base, and habitat fragmentation, but a disease from domestic dogs may be the straw that broke the tiger's back, according to the authors of a study in mBio this week. A team of scientists... Read More

Protein that delays cell division in bacteria may lead to idenfication of new antibiotics

Bacteria adjust to wide fluctuations in food supply by controlling how big they get and how often they divide. Scientists at Washington University in St. Louis have just worked out the control system E. coli use to delay division so they can bulk up when food suddently becomes abundant. What can... Read More

Polymicrobial Infections: Perhaps The Rule, Not The Exception

The recent film World War Z describes an apocalyptic event where a rabies-like virus spreads via bite wounds to the majority of Earth’s population and turns them into zombies. Since the world’s leading virologist dies early in the film, it is up to Brad Pitt’s character to find the source and cu... Read More

Pictures Considered # 7. Cocci Divide at The Equator

In 1962 Cole and Hahn published in Science an unassuming sounding paper entitled Cell wall replication in Streptococcus pyogenes. The authors asked the question: do strep cells synthesize their cell wall by intercalating new parts at different sites on their surface or does this take place at on... Read More

Bird flu researchers want to create deadly virus in lab

Researchers said Wednesday they want to create a lab version of a deadly emerging bird flu in order to study a strain that might be more infectious to people. Responding to past concerns about such research, the U.S. government said it will require extra safety measures.

The H7N9 bird flu vir... Read More

A Better Sunscreen From Bacteria? Scientists Find A Pigment That Absorbs UV Light

Sunscreen has protected millions from cancer in the last few decades since its introduction. With innovations, including water-resistant and spray types, the adoption of sunscreen has reached new heights. But recent reports that the chemicals in sunscreen can themselves turn into cancer-causing ... Read More

Minn. firm's new water filter: bacteria

A rural Minnesota water company is experimenting with a new way of treating drinking water -- using bacteria to remove the harmful pollutants.

The Lincoln Pipestone Rural Water System has been using expensive reverse osmosis to clean nitrates and nitrites from its well water. But bacteria occ... Read More

Link between MERS virus and camels worries breeders

Some Saudis are worried that the link between the MERS virus and camels is not clear and that it could affect their livelihood as sellers of camel milk.

Yet the connection between Omani camels and a MERS-like virus has brought attention to the potential hazards of purchasing camel milk that h... Read More

Piscine reovirus—a salmon virus fresh from Norway

From the Department of Wild Salmon: Over 90 percent of B.C. farmed salmon are testing positive for a recently imported Norwegian virus that causes lesions in the hearts of salmon. Should we be concerned about its effects on wild salmon, one of B.C.’s most valuable natural resources?

So we hav... Read More

How Many Microbes Are Hiding Among Us?

Microbes are everywhere—even inside us. But because so many of these bugs won't grow in the lab, scientists have had a tough time figuring out just who they are and how they live. That may soon change. By sequencing the DNA in individual cells, researchers have gotten to know 200 new microbes—an... Read More

How To Rid The Developing World Of Deadly Bacteria? Steam

By making water boil at much lower temperatures, scientists are using steam generated by the sun as a way sanitize things in places where unclean conditions often lead to disease and death.

Up to 2.5 billion people lack access to proper sanitation. They use "flying toilets" to dispose of excr... Read More

Why bacteria ditch nose to go cause trouble

Scientists have identified triggers that turn Streptococcus pneumoniae from harmless colonizer to virulent pathogen.

The bacteria harmlessly colonize the mucous linings of throats and noses in most people, only becoming virulent when they leave those comfortable surroundings and enter the mid... Read More
