The Impact of Developing Biofuels on Travel Emissions

By Emily Folk (@EmilySFolk) Approximately 29 percent of the energy the US consumes is for transportation, and about 92 percent of US transportation is fueled by petroleum products. As a result, transportation is the sector that produces the most greenhouse gas emissions in the US. With the threat of climate change and other environmental challenges looming, we need to find a way to reduce emissions from the transportation sector. Biofuels are one potential solution. What Are Biofuels? Biofuel is fuel made from organic matter known as biomass. This organic matter…

Artificial Night-Lights Are Growing, Getting Brighter

By Neha Jain @lifesciexplore As soon as it gets dark, street lights, which have become widespread in the developed world—and are rapidly expanding in the developing world—are switched on. Indeed, since the second half of the twentieth century, Earth has become brighter at night. Now, new satellite-based research shows that our outdoor artificial night-lights are still spreading to more areas on Earth and have gotten brighter over the past few years. How night-lights impact the world Outdoor lighting is regarded as a necessity, especially in highly populated areas, but artificial…

Cooling Electronics with Graphene-based Film

How many fans does it take to keep your computer from overheating? Electronic systems accumulate a great deal of heat, mostly due to the ever-increasing demand on functionality. Computer users have been using cool air (and even liquid) to reduce heat, but now researchers at Chalmers University of Technology have developed a method for efficiently cooling electronics using graphene-based film. The film is a mere 20 micrometers thick, yet has four times the thermal conductivity capacity of copper. Cooling Electronics, Protecting the Environment Getting rid of excess heat in efficient…

Fish Food Turned into Two New Biofuels

By Kate S. A common algae commercially grown to make fish food could become a future source of biofuel, according to a new study. The research team, led by Greg O’Neil of Western Washington University and Chris Reddy of Woods Hole Oceanographic Institution, has pioneered a technique that uses a single species of algae called Isochrysis to make both biodiesel and jet fuel. The scientists believe that the ability to produce two types of biofuel from one algae holds some promise for future commercialization. They stress that this is only…
