Flooring can be made from any number of sustainable materials, making it, generally, an eco-friendly feature in homes and businesses alike. Now, flooring could be even more "green," thanks to an inexpensive, simple method developed by University of Wisconsin-Madison materials engineers that allows them to convert footsteps into usable electricity.
Azure-winged magpies, an Asian bird species, take any opportunity to provide food to their group members, even without receiving any reward themselves. A team of cognitive biologists, lead by Lisa Horn and Jorg Massen from the University of Vienna, showed this type of prosocial behavior experimentally in a bird species for the first time. There are very few other animals that show such human-like generosity. The results of their study have been published in the scientific journal Biology Letters.
Using data from deep-space surveys taken by NASA's Hubble Space Telescope and other observatories, astronomers have performed a census of the number of galaxies in the universe. The team came to the surprising conclusion that there are at least 10 times as many galaxies in the observable universe than previously thought. The results have clear implications for our understanding of galaxy formation, and also helps shed light on an ancient astronomical paradox — why is the sky dark at night?
Biologists sequencing the genome of the WO virus, which infects the bacterial parasite Wolbachia, have discovered that the phage carries DNA that produces black widow spider toxin: the first time an animal-like DNA has been found in such a virus.
The first documented evidence of wild chimpanzee mothers teaching their offspring to use tools has been captured by video cameras set to record chimpanzee tool-using activity at termite mounds in the Nouabalé-Ndoki National Park in the Republic of Congo, according to new research from anthropologists at Washington University in St.
Despite their different triggers, the same molecular chain of events appears to be responsible for brain cell death from strokes, injuries and even such neurodegenerative diseases as Alzheimer’s. Now, researchers at Johns Hopkins say they have pinpointed the protein at the end of that chain of events, one that delivers the fatal strike by carving up a cell’s DNA. The find, they say, potentially opens up a new avenue for the development of drugs to prevent, stop or weaken the process.
