For years, scientists have attempted to construct new bacterial genomes from scratch, in the hope of genetically engineering a microbe that produces biofuels or drugs. Turns out, they've been doing it the hard way. A new study finds that editing existing genomes down to only the desired genes w... Read More
The movie "Extraordinary Measures," now in wide release, tells the true story of John and Aileen Crowley, whose two youngest children were diagnosed with Pompe disease. The disease, a form of muscular dystrophy, causes severe muscle weakness and difficulty breathing. John Crowley quit his job an... Read More
Fast-spreading parasite species force sex changes on their victims, induce virgin births, and turn animals into "gross monsters"—among other horrors.
Now a new study has decoded how the bacteria may be able to wreak their havoc: by shutting down immune systems.
The parasites, of the Wolbac... Read More
Two weeks after a massive earthquake leveled much of this impoverished city, a wave of new infections and injuries has emerged, further taxing the nation’s shattered health care system.
Patients whose wounds were treated in the chaotic days following the quake are now returning with deep infe... Read More
We've long been warned of swine flu's split personality: mild in most cases, but severe in a few. Now the figures are bearing this out.
The US Centers for Disease Control and Prevention reports that 282 people under 18 died in the H1N1 flu pandemic in the US, between its start in April 2009 a... Read More

Today is apparently Dropped Food Day, with two articles coming out about dropped food safety and ethics. This entry from the LA Times has a pretty funny flow chart for making a decision on whether to eat a dropped piece of food and it references a recent study into the actual biology of the 5-se...

The kind of worm and protozoan infections that are often called neglected “tropical” diseases are also common among aboriginal peoples living in the Arctic, according to a recent survey.
Outbreaks of trichinosis, a larval-worm disease commonly associated with eating undercooked pork and carn... Read More

Mankind may finally have a weapon to fight two of the world's deadliest diseases.
A University of Central Florida biomedical researcher has developed what promises to be the first low-cost dual vaccine against malaria and cholera.
There is no FDA approved vaccine to prevent malaria, a mosq... Read More
(Excerpted from MomLogic.com, a discussion site on parenting. The comments below the story provide an interesting insight into people's reaction to Dr. Tierno's advice)
Momlogic's Vivian: My kids have done it. Your kids have done it. A chocolate chip cookie or some other irresistible morsel o... Read More
The hunt for the genetic roots of common diseases has hit a blank wall.
The genetic variants found so far account in most cases for a small fraction of the genetic risk of the major killers. So where is the missing heritability and why has it not showed up?
A Duke geneticist now suggests ... Read More
A viral infection is like an uninvited, tenacious houseguest in the cell, using a range of tricks to prevent its eviction. Researchers at the Salk Institute for Biological Studies have identified one of the key proteins allowing herpes simplex virus (HSV) DNA to fly under the radar of their host... Read More

Poster's note - with one of my favorite foods being recalled due to salmonella contamination (http://www.microbeworld.org/index.php?option=com_jlibrary&view=article&id=2567)) , this study is of great importance:
In developed countries, nontyphoidal Salmonella (NTS) strains are mainly food-bor... Read More

Researchers from Japan suggest that the tree shrew may be a practical small-animal model for studying the progression of human hepatitis C virus (HCV) infection. This discovery would replace the need for rare and expensive studies using chimpanzees, currently the only validated animal model for ... Read More
Cape Cod's older HIV patients — in their 60s and beyond — face a number of health and day-to-day-living problems unique to their age.
But at the same time, they're among the lucky few to have resilient genes in the face of the deadly virus.
Of the 250 HIV-positive clients of Cape Cod Healt... Read More
Black market labs that manufacture the beauty drug Botox could also provide terrorists with the deadly botulinum toxin, officials and security experts warn. U.S. scientists found that a biologist with a master's degree and $2,000 worth of equipment could easily make enough pure toxin to theoreti... Read More
Despite a strong response from our immune defence, the body is unable to rid itself of the bacterium Helicobacter pylori. One reason for this is that this bacterium encourages elements of the immune response to remain in tissue, activating the wrong immune cells. Research results that pave the w... Read More
