## Radiocarbon: How it’s formed and used in archaeology

Introduction Willard Libby, a professor of chemistry at the University of Chicago, was awarded the Nobel Prize in Chemistry in the year 1960. This Nobel Prize was for the discovery of a technique, Radiocarbon Dating, that revolutionized the field of archaeology and palaeontology1. Radiocarbon Dating is a method used to estimate the age of carbon-containing […]

## Flywheels: Are Mechanical Batteries the Future of Energy Storage?

Figure 1: Flywheel “D10 Flywheel” by tudedude is licensed under CC BY-NC-SA 2.0 Abstract Energy storage is vital to our modern-day society as a method of reacting to the supply and demand of electrical energy[1]. Alongside the global push to transition from non-renewable to renewable energy sources, there also exists a need to improve energy […]

## ROV Golf Ball Retrieval

Posted in Other

Constructing an ROV that can operate underwater to collect the golf balls that are littering ponds all over the world will benefit the environment that is being poisoned as the golf balls decompose. It will offer a much safer method of extraction than diving for the gold balls because humans will not come into direct contact with the toxins and animals present in the water. During the construction we decided to use a 3D printer to print the wheels and scoop. We had to connect and make waterproof the motor’s wires to give more power to the ROV and we used PVC pipe to construct the body to provide buoyancy. During the construction and testing phase we encountered many setbacks. Because of our strict timeline and these unforeseen complications, we were not able to make the necessary adjustments to the ROV for it to be operational in a realistic setting.

## Preliminary Evidence: The Impact of Contingency Management on Depression and Anxiety Among Crack Cocaine Dependent Patients in Brazil

Posted in Other

Recently an epidemic has occurred in São Paulo, Brazil’s largest city of over 11 million people, where in an inner city community known as “Crackloandia”, hundreds of people are openly using crack cocaine. The purpose of this research was to examine the effect of the treatment method known as contingency management (CM) paired with standard treatment (STCM) to see whether or not this treatment would alter depression and or anxiety in the population. It was hypothesized that CM would lessen the severity of anxiety and depression in the population while they received treatment for their crack cocaine use as a secondary, indirect effect. All data for the clinical trial was collected from 45 individuals seeking treatment for crack cocaine use disorder. This study found that CM effectively reduces depression and anxiety scores in patients who abuse crack cocaine. The implications of this research find it likely that CM is a treatment option capable of treating patients with a comorbidity of anxiety, depression, and substance abuse disorders.

## The Scientific Legacy of the Manhattan Project

1 CommentPosted in Other

Caleac Rivero Introduction The Manhattan Project was a U.S. government-led project to develop an atomic bomb during World War II.[1] It will always be remembered for the resulting destruction and terror, and the direct political consequences (the arms race and the Cold War). Nonetheless, after the Manhattan Project, scientists managed to use the knowledge they […]

## How to Look for Alien Life

The possibility of extraterrestrial life has been discussed for centuries, in both scientific and fictitious work. But it wasn’t until 1992 that the first exoplanet (planet outside of our solar system) was detected, and 2001 that the first exoplanet in a habitable zone was detected [1]. This makes exoplanetology and astrobiology relatively new fields of […]

## Martha Chase: The Underappreciated Geneticist

Martha Chase was an American geneticist. In 1952, during the “Hershey-Chase Experiments,” she accompanied Alfred Hershey, helping to experimentally confirm that DNA, not protein, is the genetic material of life [1]. This discovery was awarded the Nobel Prize in Physiology or Medicine in 1969, yet excluded Chase [2]. There is not much information about the […]
