Plant profiles: Bittersweet
By: Judith C Evans
Known for its orange-red berries which appear in the fall, American bittersweet (Celastrus scandens) is a perennial woody vine. Its dark green, ovate leaves grow up to 2 inches long and turn yellowish green in the fall. Its small, greenish, 4-petaled flowers bloom in May...
Ancient bacteria found thriving in harsh, isolated, icy conditions
By: Leigh Goessl
Scientists have shared they have found evidence of an ancient community of bacteria located beneath about 70 feet (20 meters) of ice in an Antarctic lake. Experts say this will provide insight into this "unique" ecosystem. The lake where the ancient microorganisms were found is...

Plant physiology is the study of Plants. A plant physiologist studies internal plant functions and their chemical basis to learn how they grow, process nutrients and reproduce. They look at the functions of the plant and al the processes that happen in plants within its...
Is the Human Race Evolving or Devolving
By: Tom Brend
If we look into nature, there are plenty of hints for "general" evolution, not devolution. In fact, the very process of evolution is essential for linking several sub-fields of biology together: We acknowledge our DNA is a product of evolution, and we cannot help but...

Molecular dynamics is a powerful technique that uses approximations of known laws of physics to predict and analyze the motions of simulated atoms. The technique has been used to probe the function and action of many biological molecules, allowing researchers to test hypothesis to an...
Prokaryotic cellular structure and function
By: Joshua Horn - 257112
Prokaryotes are single cell organisms without membrane bound organelles. They are contrasted to eukaryotes, like plants and animals, which feature a true nucleus and membrane bound organelles. There are two kinds of prokaryotes, known as bacteria and archaea. The structure of prokaryotic cells is interesting...

Prokaryote and eukaryote are the two primary classifications for cells in organisms. Prokaryotes are single cell organisms without membrane bound organelles. Eukaryotes, on the other hand, feature a true nucleus and membrane bound organelles. While having many basic similarities, prokaryotes and eukaryotes are very different...

Prokaryotes are simply organisms that lack any membrane bound organelles in their cellular structure. They are contrasted to eukaryotes, which feature a true nucleus and membrane bound organelles. It is split into two primary domains: bacteria and archaea. They are almost entirely single cellular, though...
