Penn Scientists Find That Flow Means "Go" for Proper Lymph System Development

The lymphatic system provides a slow flow of fluid from our organs and tissues into the bloodstream. It returns fluid and proteins that leak from blood vessels, provides passage for immune and inflammatory cells from the tissues to the blood, and hosts key niches for immune cells. How this system develops hasn’t been well understood, but now researchers from the Perelman School of Medicine at the University of Pennsylvania have found from experiments in mice that the early flow of lymph fluid is a critical factor in the development of mature lymphatic vessels.

Penn Vet Study Shows Immune Cells in the Skin Remember and Defend Against Parasites

blurb: 
Now, research led by a team from the University of Pennsylvania School of Veterinary Medicine shows that resident memory T cells form in response to parasite infection. The new study found that, after infection with the parasitic disease leishmaniasis, a population of T cells with a memory for the parasite remained in the skin.

Just as the brain forms memories of familiar faces, the immune system remembers pathogens it has encountered in the past. T cells with these memories circulate in the blood stream looking for sites of new infection.

Penn Researchers Discover New Chiral Property of Silicon, With Photonic Applications

By encoding information in photons via their spin, “photonic” computers could be orders of magnitude faster and efficient than their current-day counterparts. Likewise, encoding information in the spin of electrons, rather than just their quantity, could make “spintronic” computers with similar advantages.

Fruitfly Sperm Cells Reveal Intricate Coordination in Stem Cell Replication, Penn Study Finds

Stem cells are key for the continual renewal of tissues in our bodies. As such, manipulating stem cells also holds much promise for biomedicine if their regenerative capacity can be harnessed. However, understanding how stem cells govern normal tissue renewal is a field still in its infancy.
