By Altering Bone Marrow, ‘Training’ Can Prepare Innate Immune System for Future Challenges
January 11, 2018
When you receive a vaccine against a disease like polio or influenza, your immune system gears up to defend against that particular infection. If you wind up getting chickenpox instead, or even a slightly different strain of the flu, you would be out of luck. That’s because traditional vaccines enlist the adaptive immune system, the functions of which are carried out largely by hyperspecific T and B cells, each targeted to a particular threat.
With a $450,000 Air Force Grant, Penn Physicist Will Shed Light on an Emerging Field in Physics
January 5, 2018
Bo Zhen, an assistant professor of physics in the School of Arts and Sciences at the University of Pennsylvania, has been awarded a Young Investigator Grant from the Air Force Office of Scientific Research.
Penn Researcher Awarded Swartz Fellowship to Investigate Brain Mechanisms of Learning and Memory
January 3, 2018
Gaia Tavoni, a postdoctoral fellow of the Computational Neuroscience Initiative at the University of Pennsylvania, has been named a Swartz Foundation Fellow for Theory in Neuroscience for her research proposal suggesting pathways to investigate the brain mechanisms involved in learning and memory. Tavoni said she is fascinated by the deep connections between learning and memory.
‘Silent Code’ of Nucleotides, Not Amino Acids, Determines Discrete Functions of Proteins Vital For Life
January 3, 2018
Humans possess six forms of the protein actin, which perform essential functions in the body. Two in particular, β-actin and γ-actin, are nearly identical, only differing by four amino acids. Yet these near-twin proteins carry out distinct roles. A long standing question for biologists has been, how is this possible?
Penn Engineers: Bone Marrow Transplant Stem Cells Can 'Swim' Upstream
January 2, 2018
When a cancer patient receives a bone marrow transplant, time is of the essence. Healthy stem cells, which can restart the production of blood cells and immune system components after a patient’s own are compromised, need to make their way from the circulatory system into the bones as quickly as possible. To do that, they must find the spots where blood vessels and bone are in close contact.
Commonalities in Late Stages of Different Inherited Blinding Diseases Suggest Targets for Therapy
December 20, 2017
Gene therapy holds promise for treating a variety of diseases, including some inherited blinding conditions. But for a gene therapy to be effective, one must know the precise gene responsible for a given individual’s disorder and develop a tailored treatment. For diseases that may be caused by mutations in many different genes, developing individual gene therapy approaches can be prohibitively costly and time-intensive to pursue.
Coalition Seeks to Increase Transparency on Life Sciences Career Prospects
December 14, 2017
Nine American research universities and a major cancer institute today announced plans to give would-be life scientists clear, standardized data on graduate school admissions, education and training opportunities and career prospects. The institutions formed the Coalition for Next Generation Life Science in response to the focus of many new Ph.D.s. solely on a limited number of traditional faculty positions and to the lack of good marketplace information on training and career options for talented life scientists.
Dark Energy Survey Offers New View of Dark Matter Halos, Penn Physicists Report
December 13, 2017
Dark matter, a mysterious form of matter that makes up about 80 percent of the mass of the universe, has evaded detection for decades. Although it doesn’t interact with light, scientists believe it’s there because of its influence on galaxies and galaxy clusters.
Penn Students Take on Peace, Water and Climate, First in Norway and Next in Ghana
December 11, 2017
One way to learn about climate change is to read about it, exploring the scientific literature, perusing science news and combing through reams of relevant data. Another way is to experience it firsthand. A trio of University of Pennsylvania students elected for the latter approach during the International Youth Peace Conference, held this fall in Sogn og Fjordane, Norway.
Impressions in Ink: Prints From the Arthur Ross Collection
December 8, 2017
An exhibition opening in January at the University of Pennsylvania’s Arthur Ross Gallery will feature 30 prints by French Impressionist and Post-Impressionist artists, chosen from the collection of the gallery’s founder Arthur Ross.
