Biologists have identified seven characteristics that all living things share.

Healthy soil contains billions of beneficial bacteria. These bacteria play an important role in soil and plant life and provide numerous benefits for growers.

New research provides more evidence that ancestors of modern choanoflagellates may be the evolutionary bridge linking single-celled and multi-celled organisms.

Genetically modified organisms (or GMOs) are organisms which have been modified using means other than sexual reproduction to introduce DNA from another species.

15% of cases of male factor infertility are caused by bacteria, parasites or viruses and vaginal infections can also trigger female infertility.

Critics oppose GMOs for their effects on pesticide use and effectiveness, their relationship to monocultures, their effects on developing nations, and health concerns.

Clock graphic organizer is a wonderful resource to teach the life cycle of living organisms such as butterflies, frogs, and bears.

Macro-organisms are only a small part of a soil’s make up, but they are important for healthy plants and nutrient-rich soil.

There are billions, perhaps hundreds of billions of micro-organisms in a single handful of soil.

Once thought an impossibly complex problem, the aging process has become the subject of serious scientific research, mainly due to the use of model organisms.

A homoplasy is a feature shared by different organisms that was not present in their most recent common ancestor. Homoplasies demonstrate adaptation in the living world.

Scientific classification sorts all life forms on Earth into five kingdoms: monera, protista, fungi, plantae, and animalia. Together they form the tree of life.

Chlorination of drinking water supplies has probably saved many millions of lives, and could save millions more.

Composting is the making of soil through a process that emulates nature.

Yard waste makes up as high as 30 percent of the solid waste of most municipalities in North America. Food waste makes up another nine percent. Composting uses this mater

Coral reefs' sheer diversity makes them biological and tourism hotspots, but despite that many are threatened by overfishing, pollution and climate change.

Beneficial micro-organisms in the soil stimulates plant growth. Adding compost to soil feeds these beneficial organisms. Here is a step-by-step guide to making compost.

Although the word humus is Latin for soil, humus is not soil in the strict sense. It is partially decomposed organic matter.

A summary of the Linnaean system of taxonomy, including a description of basic taxonomic categories and where the definition of genus and species fit in.

Most desert soils contain less than one percent organic matter. Good gardening soils need three to four percent.

Potential environmental pollution from dairy cow and pig effluent depends on levels of BOD, nutrients, sediments, pathogenic micro-organisms and odour-causing gases.

Three million to 50 million in one gram of soil

There are many types of algae

Composting is an environmentally-friendly and natural way of returning nutrients to the soil.

Topsoil differs in texture, content, and color depending on regions, whether the climate is temperate, arid, or desert.

Living things can be studied and classified based on their genome as well as the protein products derived from those genetic instructions.

In nature, soil is alive and is constantly being created. In gardens, we can and should make our own.

The distinction between species of sexually reproducing organisms is quite clear, but how are the lines drawn for organisms, like bacteria, that reproduce as clones?

In 2011, a collection of organisms, representing Earth's three domains of life, will blast off on a 34-month journey to the Martian moon, Phobos, and back to Earth

Philosophy and works of English great thinker Alfred North Whitehead, best known for his ideas on process philosophy.

A glossary of commonly used terms and phrase related to invasive and aquatic nuisance species

All living things are composed of one or more cells. Unlike cells, viruses, viroids and prions are acellular, nonliving parasites that require a living host to reproduce.

Infectious disease can result of cellular organisms, such as bacteria (prokaryotes), from eukaryotes (cells like ours) or from nonliving infectious agents.

Once a miniature reef, also known as a nano reef, has been stabilized, it begins to take shape by introducing living organisms extracted from coral reefs.

Plankton, phytoplankton and zooplankton are found everywhere in the oceans. Here's an overview of these different types.

Changing water flow patterns in estuaries mean they are unstable habitats for the species that reside there. Animals and plants have to adapt to deal with these changes

Infective illness is often the result of a breakdown in the relationship between our bodies and our resident micro-organisms.

Extremophiles survive harsh conditions that would otherwise be unlivable. Studying them offers clues to evolution, adaptation and the possibility of life on other worlds.

Buried deep in the genome of every species are molecular clues to the origin and evolution of that species.
