Archaeologists have found an ancient Viking comb with the word "comb" etched into it. The comb, which dates back about 1,000 years, could help researchers learn more about the evolution of Viking language.
A map of 26 ancient underwater volcanoes long hidden near Australia has been produced using 3D seismic reflection. "The technology we have used is similar in many ways to what is used to produce ultrasound images of babies, but for the Earth," said Nick Schofield, author of the study published in Geochemistry, Geophysics, Geosystems.
The hydrocarbon seas of Saturn's moon Titan may have a sea level just like Earth's, according to a pair of studies in Physical Review Letters. One study focused on creating a detailed topographical map of the moon, while the other focused on the average elevation of Titan's large lakes and seas.
Light pollution may make it harder for sparrows to fight off an infection of West Nile virus, increasing the risk of it spreading, according to findings presented at the Society for Integrative and Comparative Biology annual meeting. Researchers found that sparrows exposed to dim lights at night kept the virus in their system for at least four days, while those that were kept in darkness at night only had high levels of the virus for two days.
Beaches on the archipelago of Orkney, northeast of Scotland, appear to have concentrations of microplastic pollution similar to those of more industrialized areas, according to a study. "The fact that a relatively remote island has similar microplastics levels to some of the UK's most industrialized waterways was unexpected and points to the ubiquitous nature of microplastics in our water systems," said researcher Mark Hartl.
The results of two online surveys, published in Veterinary Medicine and Science, found that about 16% of dogs are coprophagic; dogs in multi-dog households and dogs that were "greedy eaters" were more likely to eat their own or other dogs' feces; and anticoprophagy products and training were largely ineffective. Veterinary behaviorists Debra Horwitz and Gary Landsberg say the behavior might be normal in some dogs, but it could be a medical problem in others and should be discussed with a veterinarian.
Philadelphia's Wistar Institute has been awarded a $1.4 million grant from the Bill & Melinda Gates Foundation to develop a malaria vaccine. Wistar is partnering with the Johns Hopkins Malaria Research Institute and Inovio Pharmaceuticals to create a vaccine using synthetic DNA.
This year, Minnesota will support five translational research studies through its state-funded scientific board Regenerative Medicine Minnesota, including one by Dr. Troy Lund of the University of Minnesota Stem Cell Institute, which aims to speed up the pace of stem cells in rebuilding the immune system in bone marrow transplant recipients, subsequently improving patient outcomes. The amounts of the specific grants were not disclosed by RMM, which is backed by a 10-year, $43.6 million allocation.
A high-school senior in Texas has been entering her welding projects in the Nueces County Junior Livestock Show for about six years. Jayna Grove says her entry this year -- a water feature -- took about 85 hours to complete.
About 52% of adults say they think students do not pursue degrees in science, technology, engineering and math because they believe it will be too difficult, according to a recent survey from the Pew Research Center. In fact, when asked, adults who pursued non-STEM careers said the primary barriers were cost and time.
