A team of Spanish scientists has studied the bacteria -- micro organisms that are "essential" for important processes such as nitrogen and carbon-fixing and decomposition of matter -- in the Tablas de Daimiel National Park. The scientists discovered 265 new phylum groups by using DNA analysis.

This time of year, allergies and the promise of air-conditioning tend to drive people indoors.
But for those who can take the heat and cope with the pollen, spending more time in nature might have some surprising health benefits. In a series of studies, scientists found that when people swap ... Read More
Sewage that overflows into urban creeks and streams during periods of heavy rain can promote the spread of West Nile Virus, an Emory study finds.
The analysis of six years of data showed that people living near creeks with sewage overflows in lower-income neighborhoods of Southeast Atlanta ha... Read More
Empa researchers have demonstrated how they can adjust process conditions to influence the properties of novel plasma polymer coatings containing silver nanoparticles. Tailor-made films can be generated through a one-step plasma process. The scientists developed these new coatings, which kill ba... Read More
New research reveals the unusual structure of a key protein complex that allows a herpes virus to invade cells. This close-up of the herpes virus’s “cell-entry machinery” sheds light on how herpes viruses work and provides a promising new target for antiviral drugs. The study was published onlin... Read More
The deaths of nearby relatives have a curious effect on the bacterium Caulobacter crescentus—surviving cells lose their stickiness.
Harmless Caulobacter live in nutrient-poor, aqueous environments like lakes, rivers, and even tap water. Like many other bacteria, Caulobacter form biofilms, agg... Read More
The concept of pregnancy makes no sense—at least not from an immunological point of view. After all, a fetus, carrying half of its father's genome, is biologically distinct from its mother. The fetus is thus made of cells and tissues that are very much not "self"—and not-self is precisely what t... Read More
Flu viruses mutate rapidly, meaning that vaccines against the flu have to be continually updated to target the latest strains. Moreover, antiviral medications to combat flu sometimes become ineffective because of viral mutations. Thus, finding a so-called universal flu vaccine that could be used... Read More
Researchers have made the surprising finding that graphene-based nanomaterials possess excellent antibacterial properties. Although antibacterial materials are widely used in daily life, and the antibacterial properties of nanomaterials are increasingly being explored and developed as commercial... Read More
A devastating tropical virus that has no cure can be ambushed by vaccination a day or two after exposure, tests in monkeys show. The findings suggest that African villagers, health officials and laboratory workers who come into contact with the deadly Marburg virus will someday have recourse to ... Read More
They were discovered, living virtually unnoticed, in the depths of a toxic sludge lagoon at a 100-year-old refinery in Poland.
After a trip across the ocean to the U.S. Energy Department's Savannah River National Laboratory -- and eight years of careful research -- scientists are slowly unloc... Read More
For all the images of healthy, joyous activity competitive athletes may conjure up, sports can be a germy business.
Sweat, shared gear and playing surfaces, coupled with the erratic personal hygiene of adolescents, have combined to ramp up the risk from skin infections in sports at the high s... Read More

Modern marsupials may be popular animals at the zoo and in children's books, but new findings by University at Buffalo biologists reveal that they harbor a "fossil" copy of a gene that codes for filoviruses, which cause Ebola and Marburg hemorrhagic fevers and are the most lethal viruses known t...

Not all zombies are created equal. The most popular zombie archetype is a shambling, brain-eating member of the recently deceased, but, in recent films from 28 Days Later to Zombieland, the definition of what a zombie is or isn't has become more complicated. Does a zombie have to be a cannibal c... Read More
Cell phones are accumulating a Swiss Army Knife-esqe assortment of capabilities; substituting as cameras, providing internet access, and soon operating as medical labs if Aydogan Ozcan's plans come to fruition. This month's cover article of the journal Lab on a Chip features the latest creation... Read More
Are trillions of bacteria to blame for your elastic-waist jeans and poolside muumuu? Did microbes make you devour double bowls of triple-fudge ice cream last night?
It only sounds like a horror movie. A growing stack of research suggests that the mysterious, microscopic "zoo" in your digestiv... Read More
