Do Sunscreen Products Harm the Coastal Marine Ecosystem?
By The Editors When new products based on mixtures of several chemicals become widely used, and the use of these products increases exponentially, it is reasonable to expect some sort of environmental impact, at least on specific ecosystems. Therefore, the recent finding that sunscreen products may cause deleterious effects in the coastal ecosystem is not surprising. Sunscreen products contain organic and/or inorganic UV chemical filters, as well as a variety of other ingredients, as for example preservatives, coloring agents and fragrances. What is surprising, however, is that this potential environmental problem has not been given the attention it deserves – until this year. Findings on the effects of sunscreen products…

Nanotechnology: Lycurgus Cup and Sensors
By Roberta Attanasio Nanotechnology is technology based on extremely small structures, the so-called nanostructures. How small are nanostructures? We’re talking nanoscale – about 1 to 100 nanometers. One nanometer is a billionth of a meter (there are 25,400,000 nanometers in one inch). These are the dimensions of atoms and molecules and, therefore, nanotechnology involves the manipulation of atoms and molecules. How, then, is nanotechnology different from molecular biology (sometimes called the nanoscience of living things), physics, or chemistry? The distinction can be blurred. However, when considering nanotechnology and nanostructures, it is important to take into account that nanostructures are man-made and exhibit special size-dependent properties, in other words properties resulting…

Central Asia Large Mammals: Victims of (Cashmere) Fashion
By Roberta Attanasio One thing here affects something else there. This is the principle at the basis of The Global Fool’s mission — To raise awareness of environmental problems and their global nature. Last month, a team of international researchers published the results of a study entitled “Globalization of the Cashmere Market and the Decline of Large Mammals in Central Asia”. As the title suggests, the results of the study show a disturbing link between the global cashmere trade and declining native wildlife species in India, Mongolia and China’s Tibetan plateau. In other words, there is a link between Western world fashion (one thing here) and native wild animals in Central Asia…

Facebook: High Connection and Low Well-Being
By The Editors Facebook may be big in helping people connect, but may not be that big in making people happy. Indeed, results from a study published in the scientific journal PLOSone indicate that Facebook use predicts decreases in a user’s well being. The study, entitled “Facebook Use Predicts Declines in Subjective Well-Being in Young Adults” (August 14, 2013), has been carried out by a group of investigators from the University of Michigan (U.S.) and the University of Leuven (Belgium). For the study, the researchers recruited 82 young adults, a core Facebook user demographic. All of them had smart phones and Facebook accounts. They used experience-sampling—one of the most reliable…

Large Animal Extinctions and Soil Fertility
By The Editors During the final millennia of the Pleistocene Epoch, roughly 100 genera of megafauna became extinct worldwide. In other words, between 50,000 and 10,000 years ago, the large majority of animals weighing more than 100 pounds died out Examples of these extinct animals are mammoths, the saber-toothed tigers, Diprotodon (an Australian marsupial the size of a hippopotamus) and Coelodonta (a woolly rhinoceros found in Europe). Hotly debated theories have been proposed to explain why megafauna died out. These are the overill (died because of diseases), overchill (died because of colder temperature caused by climate change), and overkill (died because of human hunting) theories. Now, results from a new…

Do Sea Turtles Eat Plastic Marine Debris? Yes!
By The Editors Floating marine debris accumulates in five main oceanic gyres. These debris accumulations consist mostly of plastics and are called great garbage patches. In recognition of the global threat posed by the great garbage patches, the United Nations Educational, Scientific and Cultural Organization (UNESCO) has recently granted them a symbolic State status, and officially recognized the Garbage Patch State. Marine debris gathers in drift lines and convergence zones, which are also important feeding areas for many oceanic species, including sea turtles. Now, results from an analysis of global research data from the past 25 years show that green and leatherback turtles are eating more plastic than ever before. The analysis…

What is Carbon Farming?
By Roberta Attanasio Greenhouse gases (carbon dioxide, methane, nitrous oxide, fluorinated gases, and ozone) work like the glass walls of a greenhouse and are responsible for the greenhouse effect. What is the greenhouse effect? It’s a process in which greenhouse gases let the radiation from the sun onto the Earth’s surface. At the same time, they trap the heat that reflects back up into the atmosphere. The greenhouse effect keeps our planet at an average 59 degrees Fahrenheit (15 degrees Celsius). However, if the greenhouse effect is too strong, our planet gets warmer and warmer. This is what is happening now — the greenhouse effect is becoming stronger because of increased release of greenhouse gases in the atmosphere.…

Benzene, Leukemia and Lymphoma
By Roberta Attanasio It’s said to have a sweet smell, or a gasoline-like odor. It’s mostly in the air, and sometime in the water and soil. It’s found all around the world. It’s in cigarette smoke and gasoline vapors. It’s a known human carcinogen – a substance known to cause cancer. It’s benzene. Its target organ is the bone marrow, the soft spongy tissue that lies within the hollow interior of long bones and produces all types of blood cells. The Agency for Toxic Substances and Disease Registry (U.S. Department of Health and Human Services) in the “Toxicological Profile for Benzene” states: “Everyone is exposed to a small amount of…

Arsenic in Rice: Links to Genetic Damage
By The Editors Rice is a staple food for over 3 billion people worldwide. Unfortunately, rice contaminated with arsenic can be found in several regions of our planet. Although serious concerns have been raised in the past few years over the consumption of rice tainted with high levels of arsenic, there was no direct proof of its harmful effects on human populations. Now, results from a new study indicate that staple consumption of cooked rice containing high levels of arsenic leads to genotoxic damage. Arsenic, one of the heavy metals, is a chemical element normally present in water, air and soil. It is released from volcanoes and from the erosion…

A Not-So-New Role for Bisphenol A: Mammary Gland Carcinogen
By The Editors Bisphenol A (BPA) is not just a harmful chemical found in many plastic products — it’s also a news champion, and our guess is we’ll keep hearing about it for a long time. The latest? BPA may act as a complete mammary gland carcinogen. BPA is a known endocrine disruptor (a chemical able to interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife) and a potential environmental obesogen (a chemical able to disrupt the normal development and balance of lipid metabolism, which can lead to obesity). Moreover, mounting scientific evidence strongly suggests a link between BPA and cancer.…
