How a microscopic team alters the course of carbon in the Atlantic ocean - Finalist in Ocean 180 Video Challenge

The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical Atlantic ocean. This runoff forms a freshwater plume, hundreds of miles across, that profoundly affe... Read More

Much breast milk bought online is contaminated, analysis shows

Desperate for breast milk, some new mothers who can't nurse their babies are turning to online sources, typically strangers with ample supplies. But a new study finds that human milk bought and sold on the Internet may be contaminated — and dangerous.

Nearly 75 percent of breast milk bought t... Read More

World Polio Day

As a virologist who has worked on poliovirus since 1979, I would be remiss if I did not note that today, 24 October, is World Polio Day. World Polio Day was established by Rotary International over a decade ago to commemorate the birth of Jonas Salk, who led the first team to develop a vaccine a... Read More

Laser tool speeds up detection of Salmonella in food products

Purdue University researchers have developed a laser sensor that can identify Salmonella bacteria grown from food samples about three times faster than conventional detection methods.

Known as BARDOT (pronounced bar-DOH'), the machine scans bacteria colonies and generates a distinct black and... Read More

Baker's Yeast Gets a Genetic Makeover

The humble baker's yeast has been enlisted to serve the needs of humanity, responsible for beer, wine and bread, among other staples. A domesticated servant for at least millennia, the microscopic fungus has now had one of its chromosomes swapped out by a host of undergraduate students in favor ... Read More

New probiotic improves pig health, reduces manure output

A new probiotic for pigs could mean less manure to manage, according to U.S. Department of Agriculture (USDA) studies. Agricultural Research Service (ARS) scientists conducted the first published investigation of the use of bacteria as a probiotic to increase fiber fermentation rates and reduce ... Read More

Lassa Fever Reported in U.S. Traveler to West Africa

A Minnesota man who returned from a trip to West Africa has been diagnosed with Lassa fever, a severe and sometimes deadly viral disease rarely seen in the United States, health officials said.

The man, who was hospitalized with fever and confusion on March 31, was confirmed to have Lassa fev... Read More

Scientists Turn Dr. Frankenstein, Re-Write Bacteria’s Entire Genome

It may sound like science fiction, but researchers at Yale and Harvard have taken the first steps towards a Dr. Frankenstein-type reality, by fundamentally changing the genetic code of an organism.

The scientists were able to rewrite the genetic alphabet of the common bacteria E.coli, creatin... Read More

Yellowstone Caldera, Wyoming

Bacterial mats, golden brown in color, seen at the outer edges of Chromatic Pools. The blue water in the center is the hottest water at ~199 F and cooling to ambient the farther you get from the center. Cyanobacteria grow around 163 F or lower. Read More

Biotransformation of Enniatins from Fusarium Fungi in a Food Safety Perspective

Mould species of the genera Fusarium and Altenaria are considered the most important threats to Norwegian grain cereals because they produce toxins which can be a potential risk to food safety. F. avenaceum, the fungi most frequently isolated from Norwegian grain, produces enniatins which have b... Read More

Computing with Slime

A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors....

Environmental Swab/Bottom of Shoe #1

On the first day of Micro class instructors have students do an environmental swab. This sample was subcultured from a student who did the bottom of their shoe. The organism, possible Bacillus sp., was tough to scrap off the agar so subculture was done by taking a small chunk of agar containi... Read More

New botox super-toxin has its details censored

A new type of botulinum toxin – the deadliest substance known – has been discovered. Because it does not yet have an antidote, the DNA sequence behind it has been withheld from public databases. This is the first time a sequence has been kept secret over security concerns.

Injecting a mere 2 ... Read More

H7N9 influenza strain resistant to antivirals, but tests fail to identify resistance

Some strains of the avian H7N9 influenza that emerged in China this year have developed resistance to the only antiviral drugs available to treat the infection, but testing for antiviral resistance can give misleading results, helping hasten the spread of resistant strains. The authors of a stud... Read More

UC Davis Researchers Find How Viral Infection Disrupts Neural Development in Offspring, Increasing Risk of Autism

Activating a mother’s immune system during her pregnancy disrupts the development of neural cells in the brain of her offspring and damages the cells' ability to transmit signals and communicate with one another, researchers with the UC Davis Center for Neuroscience and Department of Neurology h...

Are tiny microbes outwitting us to steal our food?

It's long been know that microbes are to blame for food going off and becoming rotten but in the late 1970's, Dan Janzen of the University of Pennsylvania, and a winner of ecology's version of the Nobel Prize, suggested that making something rotten may be to the advantage of the microbes living ...

Paper device spots antibiotic-resistant bacteria

Scientists in Canada have developed a paper-based device that checks if bacteria are resistant to certain antibiotics. The simple system could help users in remote areas pick the most appropriate treatment for bacterial infections.
