News: Hospital Floors May Look Clean, but They're Teeming with Deadly Superbugs—Including MRSA, VRE & C. Diff

Hospitals are places we go to get well, and we don't expect to get sick or sicker there. But a study from researchers at the Cleveland Clinic, Case Western Reserve University School of Medicine, and Cleveland VA Medical Center in Ohio found that hospital floors in patient rooms were frequently contaminated with healthcare-associated pathogens—often dangerous multi-drug resistant bacteria.

News: 4 Billion Year Old 'Fossil' Genes May Be Our Secret Weapon Against Infection

The evolution of our infection-fighting systems may have something to teach modern scientists. That's what a group from the University of Granada in Spain found when they studied a protein that's been around for over four billion years. Their work, by senior author José Sánchez-Ruiz and colleagues in the Department of Physical Chemistry, was published in the journal Cell Reports.

How To: Identify tree damage from a natural gas leak

In this how-to video, you will learn how to indicate if tree damage has occurred due to a natural gas leak. In this example, a Mexican Elder tree has been damaged by the gas leak. You can tell by the brown leaves. The plastic around the soil has trapped the gas in the soil, cutting off the oxygen from the tree. The Indian Hawthorne in this example has also been damaged. There is some foliage burn on the leaves. The bush will have to be trimmed back in order to save it. There are several plant...

Any mix can be used. The critical ingredient is oxygen. Coarse and soft mixes should be used. Water is also important. You want living ...

News: Bacteria Turned into Factories, Supplying Critical Enzymes to Make Cancer Drugs Cheaper & Save Endangered Yew Trees

Cytochrome P450 (P450s) are proteins found in nearly all living organisms, which play roles that range from producing essential compounds and hormones to metabolizing drugs and toxins. We use some of the compounds synthesized by P450 in plants as medical treatments, but the slow growth and limited supply of these plants have put the drugs' availability in jeopardy and jacked up prices.

News: Top 5 Alien Worlds That Could Host Alien Life!

Video: . Extraterrestrial life is life that does not originate from Earth. It is also called alien life, or, if it is a sentient and/or relatively complex individual, an "extraterrestrial" or "alien" (or, to avoid confusion with the legal sense of "alien," a "space alien"). These as yet hypothetical forms of life range from simple bacteria-like organisms to beings far more complex than humans. The possibility that viruses might exist extraterrestrially has also been proposed.

How To: Model a robot in 3ds Max

Building a robot in real life is not an easy task, and not usually accomplishable unless you have a degree in electrical engineering. But building one virtually on your computer is something almost anyone can do, if you know what program to use.

Soil Science: How Microbes Make Compost to Feed the Soil

Are you looking for a little microbe magic? Think composting. Composting is a great way to reuse food and plant waste that you would otherwise throw into the trash, which would just end up in a landfill somewhere. During the composting cycle, microbes reduce this organic waste until it can be fed back into the soil as rich, crumbly compost. When returned to the soil, compost feeds plants and improves the nature of life underground. Sound like a great idea? It is — and it's easy.
