USDA reviews whether bacteria-killing chemicals are masking salmonella

The Agriculture Department is reviewing research showing that new bacteria-killing chemicals used in chicken slaughterhouses may be masking the presence of salmonella and other pathogens that remain on the birds that consumers buy, according to records and interviews.

Academic researchers agr... Read More

Alien Life Hunt Looks to Earth's Underground Microbes

Hundreds of millions of miles away on Mars, NASA's Curiosity rover is looking for clues that a suitable environment for life might once have existed on our desolate neighboring planet.

Curiosity can only scratch the surface, since its drill penetrates mere centimeters below the ground. Even i... Read More

New antibiotic that attacks MRSA found in ocean microbe

A completely new and unusual antibiotic compound has been extracted from a marine microorganism found in sediments off the coast of California.

The discovery of genuinely novel antibiotics is rare, and experts say resistance to the drugs poses a grave threat to human health.

US scientists ... Read More

Complex Anticancer Compound Developed

Scientists at The Scripps Research Institute (TSRI) have achieved the first efficient chemical synthesis of ingenol, a highly complex, plant-derived compound that has long been of interest to drug developers for its anticancer potential. The achievement will enable scientists to synthesize a wid... Read More

Pandoravirus, bigger and unlike anything seen before

The discovery of the giant Mimivirus and Megavirus amazed virologists (and also many others). Their virions (750 nanometers) and DNA genomes (1,259,000 base pairs) were the biggest ever discovered, shattering the notions that viruses could not be seen with a light microscope, and that viral geno...

Kansas company recalls 50,000 pounds of ground beef products

A Kansas company is recalling about 50,000 pounds of ground beef products over fears of E. coli contamination.

The National Beef Packing Co. products, which were shipped nationwide, may be contaminated with E. coli O157:H7, the U.S. Department of Agriculture said Wednesday.

There have been... Read More

Packaged salad mix named as source of cyclospora stomach virus in some states; 372 total cases reported

Health officials in Iowa and Nebraska did not name the brands of salad mix they say are responsible for the illnesses. A total of 15 states, including New York, New Jersey and Connecticut, have reported cyclospora cases since mid-June.

Health officials in Iowa and Nebraska on Tuesday identifi... Read More

What We Can Learn From the Quantum Calculations of Birds and Bacteria

As an undergraduate at Oxford University in the mid-1970s, K. Birgitta Whaley struggled to choose between chemistry and physics. Now, as a professor at the University of California, Berkeley, and director of its Quantum Information and Computation Center, she doesn’t have to: Her research intere... Read More

Breath Analysis Reliably Indicates Presence, Level of Infection in Mice

Noninvasive method could enable rapid diagnosis in humans without need for blood tests. Breath analysis may prove to be an accurate, noninvasive way to quickly determine the severity of bacterial and other infections, according to a UC Irvine study appearing online today in the open-access journ...

How bacteria 'invest' their meagre resources to bring about evolutionary success

For the first time the complex interplay between bacterial investment strategies and their outcomes has been recreated and analysed by researchers at the University of Sydney and University of Exeter.

The study is published today in the journal Ecology Letters.

Co-author Dr Tom Ferenci fro... Read More

A Glass of Milk After Eating Sugary Cereals May Prevent Cavities

Washing down sugary breakfast cereal with milk after eating reduces plaque acid levels and may prevent damage to tooth enamel that leads to cavities, according to new research at the University of Illinois at Chicago College of Dentistry. Read More

3-D Molecular Syringes: Scientists Solve Structure of Infection Tool Used by Yersinia Bacterium

Abdominal pain, fever, diarrhea -- these symptoms could point to an infection with the bacterium Yersinia. The bacterium's pathogenic potential is based on a syringe-like injection apparatus called injectisome. For the first time, an international team of researchers including scientists at the ...

Bacteria in Brains Suggest Alzheimer’s-Gum Disease Link

Bacteria linked to gum disease traveled to the brains of people with Alzheimer’s disease, suggesting that dental hygiene plays a role in the development of the memory-robbing illness, British researchers said.

Signs of the bacterium, known as Porphyromonas gingivalis, were found in four out o... Read More

Social amoebae travel with a posse: Tiny single-celled organisms have amazingly complicated social lives

In 2011, Nature announced that scientists had discovered a single-celled organism that is a primitive farmer. The organism, a social amoeba called Dictyostelium discoideum, picks up edible bacteria, carries them to new locations and harvests them like crops.

D. discoideum enjoyed a brief spel... Read More

More on ‘Nightmare Bacteria’: Maybe Even Worse Than We Thought?

In my last post I talked about the under-appreciated emergence of “nightmare bacteria” (those are the Centers for Disease Control and Prevention’s words, not mine) that are widely distributed in hospitals and nursing homes around the world and do not respond to a last-ditch small family of antib...

How Eating the Right Bacteria Could Give Your Body Superpowers

No man is an island. If anything, every man is a sentient, mobile farm for the countless quadrillions of bacteria that colonize us. And by introducing the right bacteria into that equation, you can give your body one heck of a boost.

Every person on this planet could reasonably be considered ... Read More

In the deep, bioluminescent bacteria bloom bright

Imagine swimming to the bottom of the sea, the water growing impossibly deep and dark the farther you travel. At these depths, beyond the reach of the sun, live strange new sources of light. Fish, jellyfish, and even bacteria light up these midnight waters.

According to new research in PLOS O... Read More

Fungal biology: Finding yeast's better half

Scientists long believed that the fungal pathogen Candida albicans was incapable of producing haploid cells—which contain only one copy of each chromosome, analagous to eggs and sperm—for mating. Mixing of genes in sexual reproduction helps generate the diversity that is the raw material for evo... Read More

Microbiome research goes without a home

Trillions of microorganisms call the human body home. But ‘home’ for many US scientists studying these microscopic squatters is about to change, as funding for human microbiome research scatters across 16 of the 27 centres of the US National Institutes of Health (NIH).

Last year, researchers ... Read More
