Apothecial fungi have cup-shaped fruiting bodies lined with spore-bearing c... Read More
Duke University bioengineers have not only figured out a way to sneak molecular spies through the walls of individual cells, they can now slip them into the command center -- or nucleus -- of those cells, where they can report back important information or drop off payloads.
Using silver nan... Read More
Biologists from The University of Texas at Arlington have uncovered virus fragments from the same family of the modern Hepatitis B virus locked inside the genomes of songbirds such as the modern-day zebra finch.
The article, publishing in the online, open access journal PLoS Biology, marks th... Read More
There are bakers, and then there are sourdough bakers. A curious breed, all their own.
The most passionate among them enjoy an oddly close relationship with a living, amorphous blob, sometimes generations old, that requires warmth and constant feeding – about every eight hours.
This is th... Read More

It has taken 10 years for Dr. Beatrice H. Hahn to build the world’s most comprehensive treasury of great ape dung samples.
And now it has yielded an unexpected gem: The most dangerous form of malaria originated in gorillas, not chimps, as had long been believed.
In and of itself, knowing ... Read More
Warning: the bacterium behind Lyme disease is collaborating with its accomplices to construct a gene that can defeat your immune defenses. That’s what researchers investigating the evolution of a crucial gene in Borrelia burgdorferi found when they compared bacteria found in ticks gathered acro... Read More
Household dust contains up to 1000 different species of microbes, with tens of millions of individual bacterial cells in each gram. And these are just the ones that can be grown in the lab!
Dr Helena Rintala, speaking at the Society for General Microbiology's autumn meeting in Nottingham desc... Read More
Ever the cagey foe, Salmonella has been around for millions of years and has managed to beat thousands of attempts to eradicate it. An amazingly “smart” and resilient germ but always totally ruthless, Salmonella and its more than 2,500 different strains are always looking for new ways to survive... Read More
Swine flu no longer represents a major threat to the U.S. population, because most people are immune to the virus that caused last season's pandemic, health officials report Tuesday.
Of the 310 million people in the USA, 59% are now believed to be immune to pandemic H1N1 flu, the researchers ... Read More
Amyloid protein structures are best known for the troubles they pose in the brains of Alzheimer's patients. Now researchers are trying to exploit their presence in a very different place – in semen – to find a new way to stop HIV.
Scientists have created a substance that targets amyloid struc... Read More
Abstract - A crucial transition in the origin of life was the emergence of an informational polymer capable of self-replication and its compartmentalization within protocellular structures. We show that the physicochemical properties of ice, a simple medium widespread on a temperate early Earth,... Read More
Exposure to common viruses in daycare puts children with a chronic lung condition caused by premature birth at risk for serious respiratory infections, according to a study from Johns Hopkins Children's Center published in the October issue of Pediatrics.
The researchers say their findings sh... Read More
Anti-malarial drugs are being used inappropriately for sick children in Zambia -- a problem that can be addressed by arming community health workers with a simple rapid-diagnostic test and a supply of antibiotics, a study led by researchers at Boston University School of Public Health has found....

The 2009 swine flu virus faces two probable fates: it will either continue to cause low or moderate mortality or it will go extinct. That’s the judgment of the authors of a new Perspectives piece in mBio, which points out that the impact of the virus this flu season will depend largely on the d... Read More
Moselio Schaechter of the Small Things Considered blog discusses one of the largest biomass entities in the oceans that was explored as part of the decade-long Census of Marine Life, a global network of researchers in more than 80 nations engaged in a scientific initiative to assess and explain ...

For years researchers thought that celiac disease — whose sufferers experience an autoimmune reaction to gluten protein — began only in childhood. A new study, however, suggests not only that the number of cases is on the rise, but that the disease can manifest itself in middle-aged and even eld... Read More
