A touch of electricity may help diabetic wounds heal

When the body sustains a wound, electrical signals around the site of the injury help cells migrate there as part of the healing process. While this works well in healthy individuals, new research reveals that when such wounds happen to diabetics, the electrical fields around them are significantly weaker, leading to the slow-healing process common to people with the condition. By manipulating the electricity around wounds, the researchers feel that they might be able to speed the healing process and help diabetics thrive.Read More

Volkswagen planning electric car offensive for 2025

Volkswagen certainly hasn't done its environmental credentials any favors recently, but its most recent announcement suggests the suits in Wolfsburg are thinking well beyond the future of crude oil. The automotive giant is planning to release more than 30 new battery-powered models before 2025 in an attempt to sell between two and three million EVs by the same year.Read More

Waste tomatoes tapped as source of electricity

The tomato is a very versatile fruit. It can be juiced, made into cold soup, used as sauce or just eaten raw in a salad. It is a true food icon and now its usefulness could be expanding to an unexpected area as a US team is experimenting with the fruit as a source of electricity. A pilot project developed by researchers based in several American institutions involves a biological-based fuel cell that uses tomato waste from harvests in Florida, giving a new lease of life to organic material that would otherwise end up in landfills.Read More

Random vibrations turn tiny trees into power plants

Step aside windmills, there's a new way to harvest kinetic energy in the works. A research team at the Ohio State University has created electromechanical devices that look like tiny leafless trees and can generate electricity when they are moved by seismic activity, the slight swaying movements of a tall building, or the vibrations from traffic on a bridge.Read More

FAA testing a concrete way to clear snow

Anyone who's dealing with the current snowstorm in the US will know that clearing snow is hard work and futile if there's another dump. The University of Nebraska-Lincoln's Chris Tuan may have put an end to the need to shovel snow, however. His conductive concrete simply melts any snow that lands.Read More
