A larger percentage of patients with human immunodeficiency virus (HIV) achieved normalization of CD4+ T-cell counts when they started antiretroviral therapy (ART) within 12 months of the estimated dates of seroconversion (EDS) rather than later, according to a report published online by JAMA In...

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

»I enjoyed the article on your blog 'Six Questions About CRISPRs' by Merry Youle. I am an ex-lambdologist, having quit phage lambda in the early 70s and moved to GM-plants. There is one thing about CRISPR that I do not understand: Why did lambdologists not find CRISPR?... 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
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
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
Scientists looking to understand – and potentially thwart – the influenza virus now have a much more encompassing view, thanks to the first complete structure of one of the flu virus’ key machines. Knowing the structure allows researchers to finally understand how the machine works as a whole, a... Read More
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
When we talk about viruses, usually we focus on the suffering caused by Ebola, influenza and the like. But our bodies are home to trillions of viruses, and new research hints that some of them may actually be keeping us healthy.
“Viruses have gotten a bad rap,” said Ken Cadwell, an immunologi... Read More
Beautiful metallic colonies of E. coli growing on Endo agar which is being used mostly for differentiation and isolation of Enterobacteriaceae strains.
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
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.

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
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
Designer Wei Lei poses a challenging, and fascinating question: Would you lick a delicious treat that resembles a prickly cactus or a deadly E. coli bacterium?
The Chinese designer’s collection of sweets, Dangerous Popsicles, transforms frozen sugar water into colorful spiny treats inspired b... Read More
Scientists who unlocked the genetic code of bacteria grown from a soldier who died of dysentery say it revealed a superbug that was resistant to antibiotics decades before those drugs were in common use.
The discovery sheds light on the history of antibiotic resistance, which has become a glo... Read More
A deadly disease that is wiping out salamanders in parts of Europe will inevitably reach the U.S. through the international wildlife trade unless steps are taken to halt its spread, says University of Maryland amphibian expert Karen Lips.
The recently described fungus, Batrachochytrium salama... Read More
A music video making the rounds on YouTube entitled “One Truth,” is dedicated to all of the brave researchers, healthcare workers, and others who have put their lives on the line to save people during the recent outbreak of Ebola virus disease. Pardis Sabeti, MD, DPhil, an NIH-funded New Innovat... Read More
Many factors, both genetic and environmental, have been blamed for increasing the risk of a diagnosis of schizophrenia. Some, such as a family history of schizophrenia, are widely accepted. Others, such as infection with Toxoplasma gondii, a parasite transmitted by soil, undercooked meat and cat... Read More
Saudi scientists have found gene fragments of the deadly Middle East Respiratory Syndrome (MERS) virus in air from a barn housing an infected camel and say this suggests the disease may be transmitted through the air.
MERS, a serious respiratory illness caused by a virus known as a coronaviru... Read More
