Resourceful Microbes Reign in World’s Oceans

A research team led by Bigelow Laboratory for Ocean Sciences has discovered that marine microbes are adapted to very narrow and specialized niches in their environment. This may explain why so few of these microbes—usually less than 1%—can be grown for study in the laboratory. By utilizing new g... Read More

Deadly piglet virus spreads to nearly 200 U.S. farm sites

A swine virus deadly to young pigs, and never before seen in North America, has spiked to 199 sites in 13 states - nearly double the number of farms and other locations from earlier this month.

Iowa, the largest U.S. hog producer, has the most sites testing positive for Porcine Epidemic Diarr... Read More

Gut Bacteria Allows Insect Pest to Foil Farmers

Here is a lesson that we’re going to be taught again and again in the coming years: Most animals are not just animals. They’re also collections of microbes. If you really want to understand the animal, you’re also have to understand the world of microbes inside them. In other words, zoology is e... Read More

High-Octane Bacteria Could Ease Pain at the Pump: Engineered E. Coli Mass-Produce Key Precursor to Potent Biofuel

New lines of engineered bacteria can tailor-make key precursors of high-octane biofuels that could one day replace gasoline, scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Department of Systems Biology at Harvard Medical School report in the ...

Glowing Bacteria Control Squid Hosts

Being jolted awake every morning by an alarm clock is plenty annoying, but at least that alarm doesn’t actually live in your body.

The Hawaiian bobtail squid (Euprymna scolopes) has an internal alarm clock that’s run by a species of glowing bacteria known as Vibrio fischeri. This bacterium an... Read More

Vaccines Not to Blame for Onset of Guillain-Barré Syndrome: A Study

Vaccines, including those used in protecting against influenza, do not put a person at increased risk of Guillain-Barré syndrome despite wide-spread concerns, according to a Kaiser Permanente study published in the journal Clinical Infectious Disease.

The retrospective study spanned 13 years ... Read More

Health economics assessment of antimicrobial copper for infection control

A unique health economics assessment of copper’s role in preventing healthcare-associated infections (HCAIs) is being presented this week at the WHO’s International Conference on Prevention and Infection Control (ICPIC) in Geneva, demonstrating rapid payback on the capital investment.

Topographic diversity of fungal and bacterial communities in human skin

An interesting recent paper characterizing the fungal microbiome ("mycobiome") of human skin. It would be lovely if the TWIM crew could discuss this in an upcoming episode!

"Traditional culture-based methods have incompletely defined the microbial landscape of common recalcitrant human fungal... Read More

New palm-sized microarray grows 1,200 individual cultures

A new microarray the size of a microscope slide holds 1,200 individual cultures of fungi or bacteria and it could enable faster, more efficient drug discovery, say the authors who created the technology in their paper in mBio this week. Scientists at the University of Texas at San Antonio and th... Read More

Two Mutations Triggered an Evolutionary Leap 500 Million Years Ago

Evolution, it seems, sometimes jumps instead of crawls. A research team led by a University of Chicago scientist has discovered two key mutations that sparked a hormonal revolution 500 million years ago.

In a feat of "molecular time travel," the researchers resurrected and analyzed the functi... Read More

Gold Probes May Offer Valuable Insight Into Cancer

Nanoprobes made from gold could be used to predict people's cancer risk -- and the effectiveness of treatments, following research by University of Strathclyde academics.

The nanoprobes could allow scientists to study cancer cells in minute detail -- using a highly-sensitive imaging technique... Read More

New Palm-Sized Microarray Technique Grows 1,200 Individual Cultures of Microbes

A new palm-sized microarray that holds 1,200 individual cultures of fungi or bacteria could enable faster, more efficient drug discovery, according to a study published in mBio®, the online open-access journal of the American Society for Microbiology.

Scientists at the University of Texas at ... Read More

Scientists one step closer to preventing bacterial infections of implanted medical devices

Ground-breaking research by Australian scientists has revealed new insights into how life-threatening bacteria colonise medical devices that are implanted in the human body.

The break throughs could help tackle antibiotic resistant infections that develop in groups of microorganisms where cel... Read More

Targeted Viral Therapy Destroys Breast Cancer Stem Cells in Preclinical Experiments

A promising new treatment for breast cancer being developed at Virginia Commonwealth University Massey Cancer Center and the VCU Institute of Molecular Medicine (VIMM) has been shown in cell culture and in animal models to selectively kill cancer stem cells at the original tumor site and in dist...

The Microbes We're Made Of (video)

The human body hosts more than ten thousand different kinds of microbes. Most of these bacteria aren't harmful - in fact, many of them actually aid the immune system. From the Smithsonian Channel.

Study of Insect Bacteria Reveals Genetic Secrets of Symbiosis

Mealybugs only eat plant sap, but sap doesn't contain all the essential amino acids the insects need to survive. Luckily, the bugs have a symbiotic relationship with two species of bacteria -- one living inside the other in a situation unique to known biology -- to manufacture the nutrients sap ... Read More

Bacteria Sent Into Space Behave in Mysterious Ways

Colonies of bacteria grown aboard space shuttle Atlantis behaved in ways never before observed on Earth, according to a new NASA-funded study from Rensselaer Polytechnic Institute in Troy, N.Y. Recent findings provide important evidence of spaceflight’s effect on the behavior of bacterial commun... Read More

Powerful Gene-Editing Tool Appears to Cause Off-Target Mutations in Human Cells

In the past year a group of synthetic proteins called CRISPR-Cas RNA-guided nucleases (RGNs) have generated great excitement in the scientific community as gene-editing tools. Exploiting a method that some bacteria use to combat viruses and other pathogens, CRISPR-Cas RGNs can cut through DNA st... Read More

Discovery offers hope against deadly cat virus

What makes a harmless virus turn lethal? For the deadliest infectious disease in cats, Cornell scientists now know.

After gathering the world’s largest sample collection for feline infectious peritonitis (FIP), they uncovered the holy grail of a 30-year quest for the mutation that turns it fa... Read More
