University of Pennsylvania researchers found that inactivating interferon signaling in a mouse model of progeria, or premature aging, extended the animals’ lives.
In a new study, researchers have made insights into how the blood-brain barrier, or BBB, is maintained, identifying a protein key to the process. Delivering this protein to mice with the rodent equivalent of MS improved their symptoms.
Building prosthetic limbs and developing rain-water filtration systems may seem like they have nothing in common. But to Adrian Lievano, a University of Pennsylvania senior from Miami majoring in mechanical engineering and applied mechanics, there’s a synergy: In both cases, the user is the designer’s top priority.
Members of the Dark Energy Survey have released the first in a series of maps that show the concentration of dark matter in the cosmos. These maps, created with one of the world’s most powerful digital cameras, are the largest contiguous maps created at this level of detail and will improve researchers’ understanding of dark matter’s role in the formation of galaxies.
