Rare Pennsylvania fungus is named for Philadelphia botanist

A Philadelphia botanist who has studied rare plants for 50 years, but has never attained the honor of having a plant named for him is finally getting his due, but with a barely visible organism so rare it may never be seen again.

Dr. Alfred "Ernie" Schuyler, emeritus curator of botany at the ... Read More

Study ranks food pathogens by cost to society

Of the food pathogens that cost society the most money — in terms of medical care, lost days of work, long-term chronic health problems or deaths — half are found in poultry, pork, beef and other meat products, according to a study due for release Thursday.

For the first time, researchers use... Read More

C. diff Colonization Accompanied by Changes in Gut Microbiota: Study Hints at Probiotics As Treatment

More from the world of the ecology of the gut microbes. Infants negative for C. difficile had Bifidobacterium longum in their GI tract (positive infants did not) while infants positive for C. difficile had other species, such as Klebsiella pneumonia, that the negative infants didn't.

Chemists shed new light on antibiotics and the survival of bacteria

Research in the laboratory of Shahriar Mobashery in the University of Notre Dame’s Department of Chemistry and Biochemistry has led to further understanding of how a bacterial cell wall cross-links, an event that penicillin and other antibiotics disrupt, a step in the maturation of a cell wall t...

Professors,


I would like to thank you for the excellent podcasts regarding parasites and viruses. Although I must say, I think TWiP is more enjoyable than TWiV. I graduated with a bachelor's degree in Microbiology and a bachelor's degree in Clinical L... Read More

British screening misses most incoming latent TB

London may owe its reputation as the tuberculosis capital of Europe to the UK's TB screening programme. A new study suggests the current policy for screening immigrants from countries with a known TB problem misses 71 per cent of those who carry the disease but do not display symptoms. A policy ...

Large differences in mortality between urban and isolated rural areas

1918 influenza pandemic (Spanish flu)

In urban communities, less than 1 in 100 inhabitants died from Spanish flu in 1918, but in isolated communities up to 9 out of 10 died. An important explanation for the differences is due to different exposure to influenza in the decades before the Spanis... Read More

Social Evolution in Bacteria - SGM series via @labratting

The social behaviour of bacteria is something that I get very excited about.

One of the differences of living within a social colony as opposed to alone means that altruistic-type behaviour has to be adopted. Bacteria living within a biofilm need to excrete the sticky goo that holds the biofi... Read More

Going Off the Grid’ Helps Some Bacteria Hide from Antibiotics

Call them the Jason Bournes of the bacteria world.

Going “off the grid,” like rogue secret agents, some bacteria avoid antibiotic treatments by essentially shutting down and hiding until it’s safe to come out again, says Thomas Wood, professor in the Artie McFerrin Department of Chemical Engi... Read More

Biocontrol: Fungus and Wasps Released to Control Emerald Ash Borer

U.S. Department of Agriculture (USDA) scientists are playing a key role in efforts to contain the emerald ash borer's destructive march through the nation's forests.

Researchers with USDA's Agricultural Research Service (ARS) are testing a fungal pathogen that could be used as a biocontrol, a... Read More

NIST seeks improved recovery of samples from biohazard events

It may not be as catchy a combination as "Miss Scarlet in the parlor with a revolver," but "polyester-rayon wipes in the field followed by saline-surfactant extraction and vortexing" is the most efficient solution to an important biological game of "Clue" deduced by researchers at the National I...

Zebrafish as a model for the evaluation of virulence for Streptococcus suis

Streptococcus suis is an important pathogen in swine, and it also represents an emerging zoonotic agent.

Pigs and mice were used as model for evaluation of virulence of S. suis. However, the concept of virulence may differ depending on the experimental model that is used. Different research ... Read More

Using a 'chemical alphabet' to translate a poem into a sequence of Deinococcus radiodurans

Many artists seek to attain immortality through their art, but few would expect their work to outlast the human race and live on for billions of years. As Canadian poet Christian Bök has realised, it all comes down to the durability of your materials. Bök has written a poem, "The Xenotext", whic... Read More

Microbes Helped With BP Cleanup (video)

Naturally-occurring bacteria made quick work of tons of methane gas released in the Deepwater Horizon oil spill, researchers reported Friday.

Stealthy bacteria hide out to survive

“Through our research, we’re understanding that some bacteria go to ‘sleep,’ and that antibiotics only work on bacteria that are metabolically active,” says Thomas Wood, professor of chemical engineering at Texas A&M University.

“You need actively growing bacteria to be susceptible to antibio... Read More

New Study Sheds Light on Evolution of 2009 Pandemic Influenza A(H1N1) Virus in Japan

Analysis of mutations of the 2009 pandemic influenza A(H1N1) virus by researchers at the RIKEN Omics Science Center (OSC) has revealed major genetic differences between the virus in its early phase of infection in Japan and in its peak phase. While yielding valuable clues on the genetic origins ... Read More

Bacteria Grow Under 400,000 Times Earth's Gravity

Proving that you don't have to be big to be tough, some microbes can survive gravity more than 400,000 times that felt on Earth, a new study says.

Most humans, by contrast, can tolerate forces equal to about three to five times Earth's surface gravity (g) before losing consciousness.
