By Ian W. Bolliger ‘11 Geophysics and Planetary Geosciences, Jet Propulsion Lab National Aeronautics and Space Administration and California Institute of Technology Numerical simulations using 3D spherical and Cartesian coordinates are carried out to analyze convective properties of fluids with viscosities of varying dependence on temperature and varying Rayleigh numbers. Several MATLAB codes are developed in order to interpret the results of [...]
After a long and unforgiving week, the weekend has finally arrived and, with it, a whole slew of parties, filled with libations and fellow single college students. When the night turns out to be not as successful as planned, you retreat to the bar or your single-not-by-choice den and drown your sorrows in some more libations (provided that you’re 21 [...]
This paper examines the organization of myelinated axons, the long neuronal processes integral to long distance communication in the brain circuitry.
Meet Professor Charles M. Lieber - ranked the number one chemist by citation impact over the last decade - and read about the path that took him to where he is today.
This study investigates the stability of a three-body system, which is a difficult problem in astrophysics. The author focuses on how stability criteria are altered when considering the Kozai effect, or the periodic alternation of inclination and eccentricity in the smaller binary pair.
By Yi Cai ’11, THURJ Staff Collaborative efforts between the Harvard Medical School, Beth Israel Deaconess Medical Center (BIDMC), and Partners HealthCare founded the non-profit institution, the Harvard Clinical Research Institute (HCRI). In this joint venture headquartered near the Boston University campus, industry meets academia to advance clinical research in multiple areas, from medical device trials to quality of life [...]
By Kyle Green ‘14 and Meewon Park ‘14, THURJ Staff George Daley: A Pioneer in Stem Cell Research In recent years, the advances made in stem cell research have astounded even the greatest minds in the field. George Daley, Professor of Hematology at Harvard Medical School and Director of the Stem Cell Transplantation Program at HMMI/Children’s Hospital Boston, said, “I [...]
Hemojuvelin (Hjv) is a member of the repulsive-guidance molecule (RGM) family that upregulates transcription of the iron regulatory hormone hepcidin by activating the bone morphogenetic protein (BMP) signaling pathway in mammalian cells. Hepcidin has been called the master regulator for iron, and hepcidin expression and regulation deviations have been implicated in disease such as juvenile hemochromatosis and thalassemia. This paper evaluates the effects of hjv on hepcidin expression in embryonic zebrafish development.
By Ina Chen ‘14 and Jonathan Zhou ‘14, THURJ Staff It is common knowledge that mental abilities decrease with age. Over the years, many people have attempted to understand the processes of aging and develop methods to delay the debilitating conditions brought on by old age. Recently, advancements in the field of biology have revealed more and more about the [...]
With the rise of the field of genetics, our genes and the environment we grow up in became polarized forces, competing determinants of who we are. Ongoing scientific research, however, continues to illuminate the fact that they are not two opposing forces; instead, they continuously interact as they drive the development of living organisms.
