Russian scientists may have discovered new life forms that have been sealed off for 14 million years under 12 thousand miles of ice in Lake Vostok in the Antarctic, a network of hundreds of lakes under an ice cap that acts like a blanket, trapping the Earth's geothermal heat. If the bacteria gets out...

The hot dog that rolls off the plate, the baby’s cookie that falls on the floor, the candy bar that slides across the table--we're told we have five seconds to pick it up before it's contaminated
. Is this true?
Researcher Jorge Parada says, "A dropped item is...

We have a problem: We're just too clean
! The rise in allergies and autoimmune diseases during the past few decades may be at least partly due to our lack of exposure to the microorganisms in dirt.
We once walked barefoot in the dirt and washed it off of our food. Now we...

In 1968, a comedy called "The Odd Couple," starring Jack Lemmon and Walter Matthau, told the story of two divorced men, Felix Ungar (a neurotic neatfreak) and Oscar Madison (a fun-loving slob) who decide to live together. This is a script that plays itself out again and again as college starts and students find themselves paired with...

Secret government documents and emails reveal that a $214 million CDC bioterror germ lab
in Atlanta has had repeated problems with airflow systems designed to help prevent the release of infectious agents. The lab is violating basic laboratory operating...

According to new research, a person's mere presence in a room can add 37 million bacteria to the air every hour, in the form of material left behind by previous occupants and stirred up from the floor.
Americans spend more than 90% of their time inside. Science Daily quotes environmental engineer Jordan Peccia as saying, "We...

Can you catch the flu
from your restaurant plate? It's an important question: There are 20 million cases of acute gastroenteritis and 128,000 hospitalizations a year that are attributed to food-borne illness. Food expert Melvin Pascall says, "While there...

A study of hailstones has found large numbers of bacteria at their cores. It turns out that the bacteria help create the snow and hail, since their coating of protein causes water to freeze at relatively warm temperatures. In fact, bacteria works so well that it's used in snow-making machines.

Not by racial types
--not even by blood types--but by BACTERIA types. Each human being has thousands of different species of microbes living on our bodies, but there are just THREE

While we desperately wage war against bacteria by developing new varieties of antibiotics, there's at least SOME good news: some types of bacteria wage a kind of "civil war" against EACH OTHER. There are predators in the bacterial world that consume other bacteria, much as predators attack prey in the animal world. Some of these predator...

Bacteria can be dangerous, but they can also be useful. New research has discovered that these tiny life forms have a sense of smell. Could this be used to keep away the ones we DON'T want?
Scientists have demonstrated that a bacterium commonly found in soil can smell and react to ammonia in the air. Bacteria have already shown that...

In the wake of the oil spill catastrophe, researchers are searching harder than ever for energy alternatives. It turns out that Bacteria can help clean up the spill and it can also play a part in our use of solar energy in the future.

Toilet seats are safer than most people think they are, but it turns out that showers can be dangerous.
A film of bacteria clings to the inside of most shower heads and is pushed out by the water when you take a shower, meaning you get a large dose of warm germs. Shower heads can contain as much as 100 times the levels of bacteria found...

If BACTERIA do it, you can too! Bacteria can anticipate a future event and prepare for it. A group of researchers in the US and Israel worked together to examine microorganisms living in environments that change in predictable ways. Their findings show that these microorganisms' genetic networks are hard-wired to "foresee" what comes next in...

We once wrote about what might happen if melting glaciers release long-frozen bacteria. Now it's happening: a recent microbe that has been frozen in ice in Greenland for over 120,000 years has finally melted. Studying this could give scientists a clue about what might happen when we encounter germs on other planets.

Microbes and humans share a long history of interaction, and the most successful microbes are those that inhabit but do not kill their host, although sometimes they make us so miserable, we almost wish they would. This probably happened because certain microbes and humans evolved together and along the way, they established complex strategies...

Not only can we get bacteria FROM space, when we take it with us INTO space, it becomes MORE dangerous!
When salmonella bacteria (which we most commonly catch from raw chicken) was flown into space in special sealed test tubes, it became MORE POWERFUL. It was three times more likely to kill mice than the regular kind of salmonella found...

Numerous tests have shown that kitchen counters contain more germs that almost anywhere else in the house. Microwave ovens are good for more than just warming leftovers; they may also help protect your family from getting sick.
University of Florida engineering researchers have found that microwaving wet kitchen sponges and plastic...

We recently wrote about a superbug detector, which will mostly be used in hospitals, where antibiotic-resistant superbugs lurk. Maybe we should use these germ revealing wipes in hotel rooms, because it turns out that the average hotel room is horribly contaminated!
A group of researchers found that adults infected with the virus that...

We've updated you on the AIDS virus and the bird flu virus and both are frightening. But scientists are actually finding GOOD ways to use bacteria and viruses?in toothpaste and cold cuts!
