We know that life on earth is incredibly diverse. It can survive deep in the trenches of the ocean and in the frozen permafrost of the arctic. Surely we have much to learn from the study of life, but we also have much to learn about the virus. Even though they are not considered living things, t... Read More
Genomes provide clues for treating leukemia, endometrial cancers
Careful what you sniff. Especially if you work at an industrial hog farm. Because a small study finds that drug-resistant bacteria may hang out in the noses of some workers even after four days away from work following exposure. Almost half of the tested workers continued to harbor drug-resistan... Read More
Using magnetic fields, technique can detect parasite’s waste products in infected blood cells.
Over the past several decades, malaria diagnosis has changed very little. After taking a blood sample from a patient, a technician smears the blood across a glass slide, stains it with a special dye... Read More
Scientists from the University of Granada have successfully created magnetic bacteria that could be added to foodstuffs and could, after ingestion, help diagnose diseases of the digestive system like stomach cancer. These important findings constitute the first use of a food as a natural drug an... Read More
Two new technologies could enable novel strategies for combating drug-resistant bacteria.
In recent years, new strains of bacteria have emerged that resist even the most powerful antibiotics. Each year, these superbugs, including drug-resistant forms of tuberculosis and staphylococcus, infect... Read More
Walter and Eliza Hall Institute researcher Dr Greg Ebert has won the Bupa Health Foundation Emerging Health Researcher Award 2014 for his work on developing a new therapy for chronic hepatitis B virus (HBV) infection.
Chronic hepatitis B is a viral liver disease that affects 230,000 Australia... Read More
Microorganisms are very diverse and include all the bacteria and archaea and almost all the protozoa. They also include some members of the fungi, algae, and animals such as rotifers. Many macro animals and plants have juvenile stages which are also microorganisms. Some microbiologists also clas... Read More
A second form of the painful chikungunya virus has appeared in Brazil—one that could more easily spread, including to the U.S.
When a mosquito-borne disease first arrived in the Western Hemisphere last year, humans were relatively lucky. The disease, which causes crippling joint pain persis... Read More
Considered as an obsolete theory for many years, the transmission of acquired traits has returned to the forefront of debate thanks to the development of epigenetic research. In this context, a team of researchers has described how in Paramecia, mating types are transmitted from generation to ge... Read More
Ebola GP protein covers the virus' surface and is shed from infected cells during infection. Shed GP can trigger massive dysregulation of the immune response and affect the permeability of blood vessels.

On July 20 a man who was ill flew on commercial planes from the heart of the Ebola epidemic in Liberia to Lagos, Nigeria's largest city. That man became Nigeria's first Ebola case—the index patient. In a matter of weeks some 19 people across two states were diagnosed with the disease (with one a... Read More

Scientists who work on genomics and are funded by the US National Institutes of Health (NIH) must post their data online so that others can build on the information, the agency has said in an update to its guidelines.
The change, which expands the remit of an earlier data-sharing policy, is ... Read More
Authorities found the H5N8 strain of bird flu at a poultry farm in the central Netherlands, the same highly contagious strain as found this month in Germany and which has prompted massive poultry culls in Asia.
Dutch authorities on Sunday said they had found the H5N8 strain of bird flu at a p... Read More
Beautiful metallic colonies of E. coli growing on Endo agar which is being used mostly for differentiation and isolation of Enterobacteriaceae strains.
In 1887, Dr. Joseph Kinyoun set up his one-room Hygienic Laboratory in the Marine Hospital on Staten Island in New York to research cholera and other infectious diseases such as diphtheria, typhoid, smallpox, typhus, plague and tuberculosis. This was the beginning of the National Institutes of H... Read More
The seafloor off the coast of Chile is carpeted with bacterial mats of gigantic proportions. They cover an area as large as that of the state of Alabama. Their total weight is of the order of 100 million tons, which probably makes this the largest single species microbiome on Earth. The mats con... Read More
From Swiss to cheddar, cheeses depend on the action of microbes for their flavor and aroma. But it's far from clear how these teams of microbes work together to ripen cheese.
To a cheese-maker, that's just the beauty of the art. To a scientist, it sounds like an experiment waiting to happen.
