A dynamic landscape When James Cook first arrived in New Zealand, in 1769, the ship’s naturalist, Joseph Banks, described the country as ‘in general mountainous, especially inland, where probably runs a chain of very high hills’. 1 It would fall to future explorers and surveyors to map the country’s interior, but it wa...
The polymerase chain reaction (PCR) is a laboratory technique for "amplifying" a specific DNA sequence. PCR is extremely efficient and sensitive; it can make millions or billions of copies of any specific sequence of DNA, even when the sequence is in a complex mixture. Because of this power, amplify produce many resear...
(RxWiki News) Even before children show signs of allergies, their body may already be reacting to allergens in the air or their food. Now, researchers have found that race may play a role in children's sensitivity to developing allergies. Sensitization is a term that means a person's immune system is responding to alle...
A person’s brain is said to not reach full maturity until the age of 25. However, 90 percent of the brain develops by his/her fifth birthday and the brain continues to rapidly create synapses (brain cell connections) throughout their childhood and teen years. Because of these critical brain development periods, it is e...

In my first post, I briefly mentioned that forms are important to classical music. Not only so that you won’t look like a doofus by referring to every piece as a “song,” but, as you go down the path of becoming literate in classical music, you can identify what is what and why that particular composer chose to write in...
In 1811, Charles Deslondes, a mixed-race slave driver from Saint-Dominique, Haiti, led what would become the largest slave rebellion in American history. Composed of 500 men, many of whom had participated in the successful Haitian revolution only a few years prior, Deslondes’s army advanced on New Orleans with a milita...
As we have discussed in the earlier chapter, the cell cycle amazingly follows a regular timing mechanism. Most eukaryotic cells live according to an internal clock, that is, they proceed through a sequence of phases, called the cell cycle. During the cell cycle DNA is duplicated during the synthesis(S) phase and the co...
The Elwha River arises from headwaters in the Olympic Mountains and flows northward across Washington, emptying into the Strait of Juan de Fuca.

“What” is the most frequently used question word, yet “what” is considered to be the most challenging. It is clear what other question words are asking for: “who” asks for a person, “where” asks for a place. “What” should ask for a thing, but that is true only 5 to 10% of the time. The other 90% of the time, “what” que...
A small, feathered dinosaur known as Sinosauropteryx had a stripe across its face to help it hide from both predators and prey.

Because Tethys is made almost entirely of ice, the energy couldn't have come from radioactive decay of heavy elements in its core, he said.
