ABSTRACT For decades evidence has shown that calcifying organisms such as several types of molluscs have been found to be vulnerable to the effects of Ocean Acidification (OA). The production of calcium carbonate which is the main component used by calcifying organisms to build their shells is predicted to decline, and with the addition of […]
Abstract Since the COVID-19 was confirmed to have human-to-human transmissibility, it has become a severe global public health crisis. Since environmental factors such as temperature and humidity are critical factors affecting the transmission of other infectious diseases such as Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS), the infection rate of viruses […]
Abstract Oil pollution in oceans is a major threat to the health of marine life and humans, as well as to coastal shores and groundwater supplies. Because the natural degradation of hydrocarbon chains found in spills is slow and anthropogenic catalysts pose environmental consequences to marine life, researchers have looked towards bioremediation, which uses natural […]
By: Marina Karki : Abstract: The burning of fossil fuels releases millions of tons of carbon dioxide into the air every year creating a current atmospheric concentration of over 400 ppm [1]. This high concentration level leads to the melting of sea ice, ocean acidification and wide array of problems that go underly global climate […]
AAAS stands for the American Association for the Advancement of Science. Since its formation in 1848, it has been dedicated to the scientific community in America (and, more recently, worldwide). As part of a yearly trip, Oundle School attended the 186th installment of the AAAS annual meeting in Seattle, WA. The students were also invited […]
Abhinav Vetcha AP Research Mrs. Katie Upton May 27, 2018 Abstract The urban heat island effect occurs when temperatures in urban areas are higher than the temperatures of the surrounding environment. This effect can be caused by decreased vegetation levels, heat-trapping building arrangements, anthropogenic heat gain (due to heat produced by the high concentration of […]
Imagine you’re walking down a picturesque street. Trees line the sides of the walkway, there’s a breeze blowing, the sun is shining – maybe a little too hard. It’s just a little too humid for that time of the year. The birds that fly overhead around this time, migrating from the south, are nowhere to be seen. […]
Abstract: The world’s changing demands for crops has resulted in the genetic modification of plants’ genotypes, to increase crop yield and resist invading bacteria. Sucrose synthase (SuSy) is an enzyme that synthesizes sucrose; sucrose is integral for plant growth and the formation of carbohydrates. Two varieties of pea plants, genetically modified Pisum sativum and heirloom […]
Yara H. Shahin*, Maha A. Shaaban, Mahmoud M. Sokkar Ainshams University: Abbasia, Cairo, Egypt. 1. Abstract Access to quality, safe, and nutritious food by achieving food security is fundamental to human existence and for establishing global health care and sustainability. Although awareness of the cruciality of food security has expanded greatly, it is important to […]
Abstract Currently, the world disposes 1.3 billion tonnes of waste per year, with a projected increase to 2.2 billion tonnes by 2025 (World Bank, 2018). Out of the total waste produced in Canada, only around 27% is diverted. The other 73% end up in either landfills or incinerators, both of which increase pollution, while damaging […]
Abstract Following the repair of the Tempe dam in 2010, Tempe Town Lake has faced significant environmental consequences that pose risks to the safety of Tempe locals. This research paper analyzes the different perspectives of bio-conservationists, hydrologists, public health officials, and Tempe residents to help formulate a prospective solution to effectively address the environmental concerns […]
What does the Periodic Table have in common with Greta Thunberg, global Communism and Martian invasions? Celebrating 150 years of the development of the Periodic Table allows us to take a closer look at how related discoveries have changed the future. Apparently, the Periodic Table isn’t only used by chemists; it is appreciated by physicists […]
On May 6, the United Nations (UN) released the largest report on the state of the planet’s biodiversity in 15 years. Research was compiled from more than 15,000 government and scientific reports by over 145 different authors from 50 countries.[1] The conclusions were startling. Scientists estimate that about 1 million species are threatened with extinction. […]
Abstract An emerging environmental issue of lake calcium decline is affecting soft water shield lakes in Canada, the United States of America, and Scandinavia. Following a legacy of acid rain during the 1970s and 1980s, the consequent low pH caused rapid leaching of calcium from lakes and soil. Although pH has stabilised due to emission […]
Hypoxic regions, also known as “dead zones”, are areas of the marine ecosystem characterised by a loss, or very low concentration, of oxygen. The number of dead zones worldwide has quadrupled over the last half century.[1] Over this period, many aquatic ecosystems have perished, and a large number of water dwelling creatures have felt the […]
The first Earth Day was held nearly 50 years ago in 1970 when 20 million Americans united to launch a modern environmental movement. Since then, many innovative laws have been passed as a result of these annual mobilisations. Within a year, it lead to the formation of the United States Environmental Protection Agency, as well […]
Abstract The problems associated with microplastic pollution are less obvious and often harder to appreciate than the obvious effects of larger plastic pieces in the ocean. It is even harder to communicate to the public effectively about issues that scientists do not fully understand. The challenge is to convey both the current and the potential […]
Abstract Within the past few centuries, human population growth and increasing urbanisation have led to the deterioration of many freshwater and marine habitats. To conserve aquatic ecosystems, it is essential to better understand the responses of the habitats to such factors. The purpose of this project was to construct an Unmanned Untethered Vehicle (UUV) for […]
Abstract This work reports a revision to the stratification and circulation behaviour of the Elfrath Lake in the Lower Rhine region, Germany. Usually lakes in these temperate latitudes present a dimictic circulation, with two phases of stagnation and two phases of circulation each year. However, measurements taken during this investigation show an increasingly monomictic circulation, […]
Abstract The biosand filter is a slow sand water filtration system that is widely used in developing countries. The filter works through the use of a biological layer to kill pathogens in the water. The focus of this research was to determine the effectiveness of a biosand filter in relation to its ability to filter […]
