Penn-led Team Uncovers the Physiology Behind the Hour-long Mating Call of Midshipman Fish
According to the Guinness World Records, the longest any person has held a continuous vocal note is just shy of two minutes. That’s quite an achievement.Compared to the Pacific midshipman fish, however, the endurance of the human vocal cord is no match. Midshipman fish can generate a mating call that emits continuously from their bodies for a full hour.
With a $450,000 Air Force Grant, Penn Physicist Will Shed Light on an Emerging Field in Physics
Bo Zhen, an assistant professor of physics in the School of Arts and Sciences at the University of Pennsylvania, has been awarded a
Researcher awarded Swartz Fellowship to investigate mechanisms of learning and memory
Gaia Tavoni, a postdoctoral fellow of the Computational Neuroscience Initiative, 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.
‘Silent Code’ of Nucleotides, Not Amino Acids, Determines Discrete Functions of Proteins Vital For Life
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
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.
Q&A with H. Carton Rogers
Almost 43 years ago, H. Carton Rogers was hired as the director of public and technical services in what was then known as Penn’s Medical Library. His first task on the job? To literally move the Biology Library down Hamilton Walk from the Leidy Building to integrate it with the medical collection and create the Biomedical Library.
Commonalities in Late Stages of Different Inherited Blinding Diseases Suggest Targets for Therapy
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.
Coalition Seeks to Increase Transparency on Life Sciences Career Prospects
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.
Dark Energy Survey Offers New View of Dark Matter Halos, Penn Physicists Report
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
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.
