California Latinos have been nearly twice as likely as whites to die of H1N1 flu since the pandemic began last spring, according to statewide figures released this morning by the California Department of Public Health.
Over the same months, blacks in the state have been 50% more likely to die... Read More
HIV is striking back against the antiretroviral drugs that keep it largely in check in rich countries, thanks both to its exposure to the major drugs and to individuals who don't realise they're infected and so spread resistant strains to new partners.
Drug-resistant strains of HIV have alrea... Read More
New data offer an up-close look at the enzyme that protects the protozoa and how one compound obstructs those efforts.
After many years of study, a team of researchers is releasing data today that it hopes will lead to new drug therapies that will kill the family of parasites that causes ... Read More
Circumcision is associated with significant reductions in HIV, HSV-2 and HPV infections among men and significant reductions in bacterial vaginosis among their female partners.
METHODOLOGY/PRINCIPAL FINDINGS: We assessed the penile (coronal sulci) microbiota in 12 HIV-negative Ugandan men bef... Read More
Microscopic nematode worms can be a potent organic insecticide, killing crop-raiding bugs without harming plants or beneficial insects and without environmental side effects of chemical. The problem is that when the worms are mass-bred for agricultural purposes, they tend to, as Byron Adams says... Read More
The standard "one-size fits all" dose may not clear infection in larger adults and increases the risk that resistance will develop, they argue.
More work is needed to guide GPs on how and when to alter doses, an editorial in The Lancet to accompany the study by doctors from Greece and the US ... Read More
A new study led by researchers at NYU Langone Medical Center is shedding new light on the action of Rho, a key regulatory protein in E. coli and many other bacteria. The study, published in the Jan. 14, 2010 issue of Nature, reveals a new paradigm to understand the molecular principles of gene t... Read More
A top World Health Organization official dismissed charges Thursday that the agency exaggerated the threat posed by the H1N1 virus and that it had been unduly influenced by the pharmaceutical industry to issue dire warnings about the swine flu pandemic.
"The world is going through a real pand... Read More
About 100 million years ago, the bacterium Wolbachia came up with a trick that has made it one of the most successful parasites in the animal kingdom: It evolved the ability to manipulate the sex lives of its hosts.
"When it developed this capability, Wolbachia spread rapidly among the world'... Read More
It's not thinking in the way humans, dogs or even birds think, but new findings from researchers at the University of Tennessee, Knoxville, show that bacteria are more capable of complex decision-making than previously known.
The discovery sets a landmark in research to understand the way bac... Read More
Researchers from the University of York reported in Science online today that they have created the first genetic map for the medicinal herb Artemisia annua, which contains an extract called artemisinin that's used to help treat some forms of malaria.
Through deep sequencing of a hybrid plant... Read More

A year ago, Michael Taylor was sitting in his office at George Washington University, considering a basic mission of the federal government: making sure food is safe. He'd devoted his career to food safety, working in and out of government, and he was finally in academia where he could think dee... Read More
Histoplasma duboisii. The single nucleus, characteristic of Histoplasma duboisii (and of Histoplasma capsulatum) can be seen in many of the fungal cells. Note large cell size Read More

Oryzae is back and this time he's hanging out with the "habitual skin microbes." Note that the subtitles around 0:46 are a little confusing and may be incorrect, possibly due to a translation issue. Since I do not understand Japanese I can't tell for sure.
To learn more about microbes... Read More
U.S. Department of Energy Secretary Steven Chu today announced the investment of nearly $80 million under the American Recovery and Reinvestment Act for advanced biofuels research and fueling infrastructure that will help support the development of a clean sustainable transportation sector. The ... Read More
Biological warfare and bioterrorism are as old as fourth-century BCE Scythian fighters wiping their arrows on decomposing bodies before shooting them at their enemies and as new as ricin toxin delivered to a US Senate mailroom in 2004. They consist of using viruses, bacteria, fungi and other tox... Read More
It is known that viral "squatters" comprise nearly half of our genetic code. These genomic invaders inserted their DNA into our own millions of years ago when they infected our ancestors. But just how we keep them quiet and prevent them from attack was more of a mystery until EPFL researchers re... Read More
