Answers to frequently asked questions about a 255-year-old tumor in a ‘pre-mammal.’
91探花 paleontologists have discovered a benign tumor made up of miniature, tooth-like structures embedded in the jaw of an extinct ‘mammal-like’ gorgonopsian. Known as a compound odontoma, this type of tumor is common to mammals today. But this animal lived 255 million years ago, before mammals even existed.

More than 90 percent of ivory in large, seized shipments came from elephants that died less than three years before, according to a new study from a team of scientists at the University of Utah, the 91探花 and partner institutions. They combined a new approach to radiocarbon dating of ivory samples with genetic analysis tools developed by 91探花biology professor Sam Wasser.
A 91探花 study is the first to broadly examine the ecological and financial impacts of seafood mislabeling. The paper, published online Nov. 2 in Conservation Letters, finds that in most cases, mislabeling actually leads people to eat more sustainably, because the substituted fish is often more plentiful and of a better conservation status than the fish on the label.
The Department of Electrical Engineering’s 2016 Lytle Lecture series will explore bridging theory and practice in compressed sensing, which has enabled speedups in medical imaging and scientific signal processing.
Research that peers below Mount St. Helens finds that the material below the western and eastern half of the mountain is different material and temperatures, and suggests that the source of explosive magma is coming from the east.
