A Pill Filled with Bacteria Instead of Drugs

Delivering healthy bacteria in a pill could help patients harboring out-of-balance microbial communities. Yogurt eaters already know that not all bacteria are bad for you. They may not realize that some bacteria are so important that one day people may fight off disease with pills filled with ba... Read More

Gene prevents buildup of misfolded cell proteins

Much like how a snowplow is needed to clear streets of heavy snow, cells employ a set of genes to clear away misfolded proteins, to prevent them from accumulating and destroying the cell.

For the first time, Cornell researchers have demonstrated how a gene called SEL1L plays a critical role i... Read More

Symbiotic Fungi Inhabiting Plant Roots Have Major Impact On Atmospheric Carbon

AUSTIN, Texas — Microscopic fungi that live in plants' roots play a major role in the storage and release of carbon from the soil into the atmosphere, according to a University of Texas at Austin researcher and his colleagues at Boston University and the Smithsonian Tropical Research Institute. ...

Holidays Bring Flu as Virus Hits Young Adults at Year End

Family gatherings helped spread influenza during the 2013 holiday season, as the pace of flu reports jumped at year end, according to the U.S. Centers for Disease Control and Prevention.

About 4.3 percent of doctor visits during the week ended Dec. 28 were for complaints of flu-like symptoms ... Read More

Studies Show Big Advance In HIV Prevention

Exciting research suggests that a shot every one to three months may someday give an alternative to the daily pills that some people take now to cut their risk of getting HIV. The experimental drug has only been tested for prevention in monkeys, but it completely protected them from infection in... Read More

Molecule Plays Important Role in Triggering Immune Response

The nucleoside adenosine—a tiny chemical structure made up of a simple base linked to a sugar—is critical for the regulation of bodily functions ranging from blood flow to tissue repair to sleep. Now, researchers at Rutgers New Jersey Medical School show that adenosine is essential in promoti... Read More

Probiotics not for colic? A response

This week a study published in the British Medical Journal, and reported in the Daily Mail, has reported that a strain of bacteria known as Lactobacillus reuteri DSM 17938 is not effective in helping to reduce symptoms of colic in babies.

However here we examine the nature of the study, and i... Read More

Mexican technology saves papaya production by detecting virus

Mexico is considered one of the leading countries in papaya productions, but its crops are usually affected by the virus of the ringed spot, which leaves ring marks in the skin of the fruit and causes softening of the papaya, where fungi start to digest it. This is why the Center of Research and... Read More

We Are Our Bacteria

Like ecosystems the world over, the human microbiome is losing its diversity, to the potential detriment of the health of those it inhabits.

Dr. Martin J. Blaser, a specialist in infectious diseases at the New York University School of Medicine and the director of the Human Microbiome Program... Read More

Plant scientists unravel a molecular switch to stimulate leaf growth

Mechanisms that determine the size of plants have fascinated plant scientists of all times, however they are far from understood. An international research team led by plant scientists from VIB and Ghent University report an important breakthrough in the scientific journal The Plant Cell. They i... Read More

The Vaccination Effect: 100 Million Cases of Contagious Disease Prevented

Vaccination programs for children have prevented more than 100 million cases of serious contagious disease in the United States since 1924, according to a new study published in The New England Journal of Medicine.

The research, led by scientists at the University of Pittsburgh’s graduate sch... Read More

Nanoparticle That Mimics Red Blood Cell Shows Promise as Vaccine for Bacterial Infections

A nanoparticle wrapped in material taken from the membranes of red blood cells could become the basis for vaccines against a range of infectious bacteria, including MRSA (methicillin-resistant Staphylococcus aureus), an infection that kills tens of thousands of people every year.

Researchers ... Read More

Genetically identical bacteria can behave in radically different ways

Although a population of bacteria may be genetically identical, individual bacteria within that population can act in radically different ways.

As these bacterial cells divide, chemotaxis machinery (bright blue and red) localize in one daughter cell

This phenomenon is crucial in the bacter... Read More

New yeast species travelled the globe with a little help from the beetles

Researchers from the National Collection of Yeast Cultures (NCYC) at the Institute of Food Research (IFR) have identified a new globe-trotting yeast species that lives on tree-associated beetles. This new species demonstrates the importance of preserving biodiversity, as yeasts like this may hel... Read More

New Virus Related To Smallpox Is Found In Republic Of Georgia

Two herdsmen in the country of Georgia have been infected with a brand-new virus, scientists from the Centers for Disease Control and Prevention said Thursday. The newly identified virus is a second cousin to smallpox. And, like smallpox, it causes painful blisters on the hands and arms‎. Other ... Read More

Breaking Big: Small scale studies on basic biology of bacteria may have a big impact on tick-borne disease research

Tick-borne diseases are a global health problem. Based on data from large cross-sectional surveys conducted in the U.S., the CDC increased estimates of Lyme disease incidence in 2012 from approximately 30,000 new cases to over 300,000 in 2012. In comparison, the CDC estimates roughly 56,000 annu... Read More

Thanks to Climate Change, West Nile Virus Could Be Your New Neighbor

Invasive species aren’t just species—they can also be pathogens. Such is the case with the West Nile virus. A mosquito-borne virus identified in the West Nile subregion in Uganda in 1937—hence the name—West Nile wasn’t much of a concern to people elsewhere until it broke out of Africa in 1999. T...
