When science revises its stance, the field itself follows established protocol to adapt, but public opinion can be slow to catch up. Rather than wiping the slate clean, last month's retraction of a key paper proposing a link between childhood vaccines and autism seem only to have widened the soc... Read More
Taken from Microbe magazine, this article discusses high-throughput gene arrays, used to analyze microbial communities, and to link their structures to how they affect ecosystems. Read More
A team of scientists in the United Kingdom and the Netherlands are reporting disturbing evidence that soil microbes have become progressively more resistant to antibiotics over the last 60 years. Surprisingly, this trend continues despite more stringent rules on use of antibiotics in medicine an... Read More
The Norwegian dairy company TINE is now planning an in-depth study that will find out whether household bacteria can be used for their own sake.
When the Norwegian dairy company TINE makes cheese, it deliberately adds certain organisms to the raw milk. Others get there by chance and shape the... Read More
The chief veterinary officer of the Netherlands has defended the country's decision to cull thousands of goats in an effort to control an unprecedented outbreak of Q fever.
The Netherlands "can't take a chance", Christianne Bruschke told Nature after a meeting in Breda -- a city near the hear... Read More
The human gut holds microbes containing millions of genes, say scientists.
In fact, there are more genes in the flora in the intestinal system than the rest of our bodies. So many that they are being dubbed our "second genome".
A study published in the journal Nature details the analysis o... Read More
How’s this for irony – the U.S. Food and Drug Administration is warning consumers to stop using two brands of hand sanitizers because they contain … dangerous bacteria.
That’s right. “Bee-Shield Hand Sanitizer” and “MD Quality Hand Sanitizer” (both made with aloe vera) were found to have high... Read More

As climatologists weather the IPCC controversy, another storm is brewing, and this one is filled with not with bloggers but with beasts, bugs and bacteria. It is the potential plague of infectious diseases—threatened to be made worse, many scientists propose, by projected changes in the Earth's ... Read More
Understanding how plants defend themselves from bacterial infections may help researchers understand how people and other animals could be better protected from such pathogens.
That’s the idea behind a study to observe a specific bacteria that infects tomatoes but normally does not bother the... Read More
Currently, beachgoers are informed about water-quality conditions based on results from the previous day's sample. Scientists must collect samples in the field, then return to a lab to culture them for analysis — a process that takes a minimum of 24 hours.
Now, engineers from the UCLA Henry ... Read More
A new study by a former U.S. Food and Drug Administration (FDA) economist estimates the total economic impact of foodborne illness across the nation to be a combined $152 billion annually.

Idaho National Laboratory biologist Frank Roberto squats on a gravelly patch of ground in Yellowstone National Park. At his feet, scalding water churns in a mustard-yellow pool the size of a wheelbarrow. Roberto reaches in with a plastic vial and scoops up a half-cup.
“That’s a good sample,” ... Read More
Scientists in Manchester, UK have found a clean and green way of making tiny magnets for high tech gadgets—using natural bacteria that have been around for millions of years. The work by a team of geomicrobiologists from the Univ. of Manchester paves the way for nanometer-size magnets – used in ... Read More
Scientists in the US have developed a microdevice that investigates how bacteria communicate with each other to enhance their resistance to drugs.
Bacteria communicate in a process called quorum sensing, in which they secrete small signalling molecules called autoinducers. When bacteria pr... Read More

Women older than 40 are unlikely to get much benefit from the vaccine for the virus that causes cervical cancer, a new study reports.
The vaccine for human papillomavirus, or HPV, is recommended for women up to age 26 and girls as young as 9. To determine whether older women might be protect... Read More
With help from scientists from Stanford University’s medical school, North Korea has developed its first laboratory capable of detecting drug-resistant tuberculosis, scientists involved in the project said last week.
Tuberculosis surged in the Democratic People’s Republic of Korea during the... Read More
