Flagellates are single celled animals, protozoans, that are characterised by the presence of a whip-like flagellum, which they use for locomotion. Choanoflagellates are a subgroup which are distinguished by having a single flagellum surrounded by a collar of microvilli, which are tiny hair-like structures. Choano...

Parasites are often hard to identify because they are so adapted to their parasitic way of life. Strepsiptera are no exception. They are insects to be sure but exactly who they are related to is more difficult to ascertain. Most people have never seen a...

Heliozoans are amoeboid protozoans. That is, they are single-celled organisms that move by the flow of their cytoplasm rather than by using oar-like cilia or whip-like flagellae. Heliozoa means sun-animals and they do resemble tiny suns for they are round with rays coming out in...

Cells are the basic structures of all true life forms. If it is alive, it has cells. The first life forms were single cells. They evolved billions of years ago and existed for billions of years before multicellular life evolved. All multicellular life forms have...

The theory of evolution is more than just a theory about how humans came to be. Whether or not that part of the theory is correct does not have much of an influence on the underlying idea that life adapts. Throw in the concept of...

Zoraptera is a small order of insects that is poorly known and understood. The name zoraptera means 'true wingless' so they were named before the winged forms were discovered. The delightful common name is angel insect. There is only a single family in the order...
Tech breakthrough promises faster, cheaper gene sequencing
By: Terrence Aym
Faster and less expensive gene sequencing holds the promise of speeding up the discovery of cures for genetic disorders and the elimination of whole categories of diseases. To that aim, the Human Geneome Project was launched in 1990.Walter Fiers at the University of Ghent...
Introduction to lacewings: Order Neuroptera
By: M E Skeel
Delicate lacewings and ferocious ant lions don't look like they have much in common but they are both members of the insect order Neuroptera. The lacewing is the adult form and the ant lion is the larval form of this holometabolous insect group. The adults...

Species of microorganisms exhibit divergence in degrees of susceptibility to different antibiotics. In addition to this, an organism's susceptibility to a given antibiotic may change. This is especially true during treatment. For the most satisfactory results in treatment, a clinician has to know the identity...
