I’m reeling from this episode!! The symbiosis, the web of life, the energies, chemicals, organisms of
Researchers have discovered the largest virus ever, and they've given it a terrifying name: Pandoravirus.
A typical virus is a tiny sack of genetic material that injects itself into a much larger cell and uses it to make more viruses. The Pandoravirus is enormous by comparison—large enough to... Read More
A type of fungus coating much of the stored corn, wheat, rice and nuts in developing countries may be quietly worsening the AIDS epidemic, according to a paper published today in the World Mycotoxin Journal.
Kept in sacks piled in barns and warehouses, food stores in countries near the equato... Read More
Studying bacteria from the Baltic Sea, UA researchers have discovered an entire array of previously unknown viruses that barely resemble any of the known bacteria-infecting viruses.
Researchers of the University of Arizona's Tucson Marine Phage Lab have discovered a dozen new types of unknown... Read More
Purple bacteria contain pigments that allow them to use sunlight as their source of energy, hence their color. Small as they are, these microbes can teach us a lot about life on Earth, because they have been around longer than most other organisms on the planet. University of Miami (UM) physicis... Read More
You wouldn’t know it, but there is an elaborate stealth communication network in the Earth beneath your feet. This smart web acts like a superorganism, fortifying defensive capabilities and coordinating deadly attacks on unsuspecting targets. But it’s not run by the NSA, the CIA, or the military... Read More
Microbiologists are trying to work out whether use of antibiotics on farms is fuelling the human epidemic of drug-resistant bacteria.
The sight of just one boot coming through the doorway cues the clatter of tiny hoofs as 500 piglets scramble away from Mike Male. “That's the sound of healthy ... Read More
Health officials are watching in horror as bacteria become resistant to powerful carbapenem antibiotics — one of the last drugs on the shelf.
As a rule, high-ranking public-health officials try to avoid apocalyptic descriptors. So it was worrying to hear Thomas Frieden and Sally Davies warn o... Read More
The production of Metallo-β-lactamase is one of the resistance mechanisms of Pseudomonas aeruginosa. Metallo-β- lactamases are members of Group B in the molecular classification of Ambler and are Clavulanic acid resistant enzymes which require divalent cations of zinc as co-factors for enzymat...

Poliovirus has been found in sewage in Israel. The virus detected is not vaccine-derived poliovirus; it is wild-type 1 poliovirus, the strain that occurs naturally in the wild and which the World Health Organization is trying very hard to eradicate from the planet. Read More
In a twist on "survival of the fittest," researchers have discovered that evolution is driven not by a single beneficial mutation but rather by a group of mutations, including ones called "genetic hitchhikers" that are simply along for the ride. These hitchhikers are mutations that do not appear... Read More
Scientists have for the first time traced a novel virus that infected two men from northwestern Missouri in 2009 to populations of ticks in the region, providing confirmation that lone star ticks are carrying the recently discovered virus and humans in the area are likely at risk of infection. T... Read More
Researchers believe they have uncovered unique, advantageous machinery for aquatic life.
Land plants can "see," but can microscopic plants see better? New research from Indiana University has uncovered a give-and-take communication system between and within photoreceptors in freshwater-dwelli... Read More
The organism was initially called NLF, for “new life form”. Jean-Michel Claverie and Chantal Abergel, evolutionary biologists at Aix-Marseille University in France, found it in a water sample collected off the coast of Chile, where it seemed to be infecting and killing amoebae. Under a microscop... Read More
One third of people diagnosed with throat cancer are infected with a form of the HPV virus, a study suggests.
HPV (human papillomavirus) is the major cause of cervical cancer, and the virus is known to spread through genital or oral contact.
Actor Michael Douglas is reported to have spoken... Read More
Here's an amazing video from PBS Digital Studios' “Under H2O” series, with micro images of corals.
Corals are beautiful when seen through your own eyes in sunlight, but for scientists at the University of Hawaii, seeing corals in this manner is not enough. They are using a revolutionary new t... Read More
Usman, who limps on a leg bowed by the polio he caught as a child, made sure that his first three children were protected from the disease, but he turned away vaccinators when his youngest was born.
He was furious that the Central Intelligence Agency, in its hunt for Osama bin Laden, had stag... Read More
An animal model of the human norovirus created at the University of Michigan Health System lays the groundwork for understanding the biology of the pesky virus and developing antiviral drug treatment.
Well-known as the virus that impacts cruise ship vacations, norovirus leads to misery on lan... Read More
Not so long ago, most people thought that the only good microbe was a dead microbe.
But then scientists started to realize that even though some bugs can make us sick and even kill us, most don't.
In fact, in the past decade attitudes about the bacteria, fungi, viruses and other microbes l... Read More
