The composition of a vast plume of hot rock and briny fluid 200 miles beneath Yellowstone National Park's surface has been mapped, a soon-to-be published study says. Researchers are able to receive a clear picture of the type of material that activates Yellowstone's volcanic features through these "geoelectric" images of the plume, says study co-author Robert B. Smith, professor emeritus at the University of Utah and coordinating scientist of the Yellowstone Volcano Observatory. "This is the...

Conductivity image hints volcano plume is bigger than thought University of Utah geophysicists made the first large-scale picture of the electrical conductivity of the gigantic underground plume of hot and partly molten rock that feeds the Yellowstone supervolcano. The image suggests the plume is even bigger than it appears in earlier images made with earthquake waves. "It's like comparing ultrasound and MRI in the human body; they are different imaging technologies," says geophysics...

Fossil teeth show who ate what and when as grasses emergedFossil teeth of African animals show that during the past 10 million years, different plant-eating critters began grazing on grass at different times as many switched from a salad-bar diet of tree leaves and shrubs, says a University of Utah study.The first animals to hit the hay "“ technically warm-season grasses known as C4 plants "“ were zebras' ancestors, starting 9.9 million years ago. Next, some but not all rhinos...

Government-sponsored analysis led by Johns Hopkins bioethics scholar published today in Pediatrics. State laws and policies governing the storage and use of surplus blood samples taken from newborns as part of the routine health screening process range from explicit to non-existent, leaving many parents ill-informed about how their babies' left over blood might be used, according to a team led by a member of the Johns Hopkins Berman Institute of Bioethics, in collaboration with researchers...

The goal: Room-temperature spintronic computers University of Utah researchers built "spintronic" transistors and used them to align the magnetic "spins" of electrons for a record period of time in silicon chips at room temperature. The study is a step toward computers, phones and other spintronic devices that are faster and use less energy than their electronic counterparts. "Electronic devices mostly use the charge of the electrons - a negative charge that is moving," says Ashutosh Tiwari,...

Green on satellite images warns of hantavirus outbreaks The risk of deadly hantavirus outbreaks in people can be predicted months ahead of time by using satellite images to monitor surges in vegetation that boost mouse populations, a University of Utah study says. The method also might forecast outbreaks of other rodent-borne illnesses worldwide. "It's a way to remotely track a disease without having to go out and trap animals all the time," says Denise Dearing, professor of biology at the...
