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
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
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
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

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
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

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
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.

Creating and maintaining a clean, sustainable water supply means delivering drinking water and collecting wastewater while dealing with pathogenic microorganisms ... Read More
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
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
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...

This video contains images of LaDuke hot spring in Gardiner, Montana, along the Yellowstone River, near Yellowstone National Park. The images show the rich mat community of chlorophototrophic bacteria that grow along the hot spring's effluent channel. The dark-green-colored organisms are mainly ... Read More
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
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
Researchers often describe the battle between the Ebola virus and the humans it occasionally infects as a race—one that people win only if their immune systems manage to pull ahead before the virus destroys too many of their internal defenses. What they may not know is that the virus is a cheat.... Read More
