President Amy Gutmann comments on the potential advantages of a study on synthetic biology.
PHILADELPHIA –- Researchers at the University of Pennsylvania report that a new test for measuring the ability of gravity to bend light seen from distant stars around large objects like black holes may offer proof of the existence of extra dimensions in the universe.
PHILADELPHIA -– Researchers at the University of Pennsylvania have developed a new electronic method for detecting microRNA isolated from living cells. MicroRNAs are a class of small biomolecules that control gene expression into proteins, the “workers” of the cell. MicroRNAs act by binding to specific messenger RNAs that code for proteins, and, by doing so, inhibit protein synthesis.
PHILADELPHIA –- A fossil found more than 150 years ago has now been identified as the remains of a new species of dinosaur, the herbivore Kukufeldia tigatensis. The study was led by University of Pennsylvania graduate student Andrew McDonald and paleontologists from the Natural History Museum, London.
