In music, notes can have different pitches. Pitch refers to how high or low a sound’s frequency is. Whether the note is C sharp or E-flat, these tonal differences allow us to have a great sense of musicality and a sharp acuity to the various notes. Although many people struggle with finding the correct pitch,… Read more

Helium-Sodium Compound Forms Under High Pressures

Helium-Sodium Compound Forms Under High Pressures

Helium, the second element in the periodic table, possesses an electron configuration which prohibits it from forming bonds with other atoms. The 1s^2  electron configuration indicates the element has a complete outer shell containing two electrons. In addition, helium possesses zero electron affinity—the energy change that occurs when an electron is added to a gaseous… Read more

Nickel Extraction Through Electrochemical Process

Nickel Extraction Through Electrochemical Process

New Caledonia, an island in the Southwest Pacific Ocean, contains ten percent of the world’s nickel reserves and is one of the world’s largest nickel producers. While nickel mining plays an important role in the island’s economy, it also poses a significant danger to humans and other organisms. Nickel (and other heavy-metal) runoffs contaminate surrounding… Read more

Synthesizing Enamel-Like Materials

Synthesizing Enamel-Like Materials

A team of researchers from the University of Michigan led by Nicholas Kotov has synthesized a material possessing a similar structure to natural enamel. Enamel—the non-living outer coating of teeth—comprises of parallel microscale and nanoscale columns of stiff, inorganic material embedded in a protein matrix. Because of its unique composition and structure, enamel can endure… Read more

Too Sex-y For My Science: The Difference Sex Makes In Preclinical Data

Too Sex-y For My Science: The Difference Sex Makes In Preclinical Data

In 2014, The National Institutes of Health (NIH) made a bold statement: essentially, future studies of animals and cells would have to take place in both sexes, or risk losing funding. This move has not been without criticism, time and cost being the two issues most often raised. However, there are some worries that sex differences in preclinical… Read more

Metal-Extracting Plants

Metal-Extracting Plants

Heavy metals play a significant role in our everyday lives, from the individual components of your smartphone to the gasoline you insert into your car. However, at low concentrations, these high-density metals are hazardous to human health. Human activities, such as mining and industry, have exposed and led to accumulations of these toxic chemicals in… Read more

Accessing the Wisdom of Crowds

Accessing the Wisdom of Crowds

People often say that the wisdom of the crowd is greater than the wisdom of any individual. However, this statement does not always hold true. If your child had a mass growing out of their side, would you want to poll a random crowd of 100,000 citizens or one specialized oncologist? The obvious answer is… Read more

Zealandia: The Eighth Continent

Zealandia: The Eighth Continent

A Geographical Breakthrough It might be time to forget what you’ve learned in geography class. A group of scientists led by Nick Mortimer recently published a journal which suggests that there is a mass of continuous land including New Zealand, New Caledonia, and various surrounding islands. But it hasn’t been exactly a new idea– scientists have long… Read more

Water Access and Childhood Illness

Water Access and Childhood Illness

Over 20 million people in the United States do not have access to clean, treated drinking water. This issue is growing rapidly in urban areas of the country. A researcher at Florida State University’s Geology Department examined a potential link between untreated drinking water, childhood illness, and climate change. In particular, he analyzed childhood gastrointestinal (GI)… Read more

Is Ethidium Bromide Safe?

Is Ethidium Bromide Safe?

One of the most important steps in genotyping is gel electrophoresis. After this step, it is important that the gel is visualized. This process is typically accomplished by staining the DNA. While some stains allow the direct visualization of DNA bands, many require the gel to be exposed to UV light. One of the most… Read more
