Biotech Firms On Quest For Apoptotic Therapies
Paul Smaglik | Mar 15, 1998 | 7 min read
DECOY RECEPTORS: Genentech's Avi Ashkenazi suspects that using ligands to bind to decoy receptors present in healthy cells, but not in cancer cells, could trigger apoptosis in tumors. Scientists studying signal transduction have spent the past several years piecing together the cell's apoptotic machinery-the complex signaling mechanisms that tell damaged cells to commit suicide. The discovery of more signaling proteins and their receptors has given biotechnology companies potential tools to fi
NIH Is Advised To Expand Its International Activities
Thomas Durso | Mar 2, 1997 | 9 min read
Sidebar: Advisory Panel's Recommendations to NIH But budget concerns may force the agency's heralded Fogarty Center to stand pat A comparatively small proposed budget increase for the center that coordinates international programs of the National Institutes of Health may prevent any significant expansion of its global efforts in the near future. A report submitted last fall by an external advisory panel recommended "a strengthening of international activities" at NIH (see list of recommendatio
Researchers Setting Up Labs Must Learn Skills On The Fly
Karen Young Kreeger | Mar 2, 1997 | 10 min read
Also in this story : Six Common Mistakes For More Information ... Setting up one's first lab can be a tortuous process requiring many decisions. Researchers must choose what kind of lab they want to run and the role they want to establish with technicians, students, and colleagues, among others. But guidelines on how to make those decisions and skills like managing a lab budget or hiring the right employees aren't taught to budding scientists. Many researchers say they learned what works best t
Scientists Debate RNA's Role At Beginning Of Life On Earth
Ricki Lewis | Mar 30, 1997 | 9 min read
Sidebar: RNA's Role at Beginning of Life - For Further Information Before there was life, there were chemicals. The idea that ribonucleic acid (RNA), because of its catalytic capability and multiple roles in protein synthesis, was the chemical that led directly to life is termed the RNA world hypothesis. Although the phrase "RNA world" is generally attributed to Walter Gilbert, Harvard University's Carl M. Loeb University Professor, in a short 1986 paper, the idea of RNA's importance at the beg
Online Access Is Profoundly Changing Scientific Publishing
Carol Cruzan Morton | Mar 30, 1997 | 9 min read
See rebuttal to this article. Scientific publishing is undergoing a profound change. Large and small, commercial and nonprofit publishers are beginning to shift journal delivery from paper to electronic and from library shelves to users' desktops. Without question, the electronic age is speeding up information access. For example, from a computer desktop in his or her office, a subscriber to the online edition of the Journal of Biological Chemistry (JBC) can browse the latest issue shortly af
SIX COMMON LAB MANAGEMENT MISTAKES
K. Y. K. | Mar 2, 1997 | 2 min read
SIX COMMON LAB MANAGEMENT MISTAKES Date: March 3, 1997 A few researchers have started to address the need to discuss the various ways of setting up and running a lab. At the Society for Neuroscience's annual meeting last November, Women in Neuroscience-an independent organization supported in part by the society-sponsored a symposium called "Running a Laboratory: Issues in Scientific Style." One of the speakers was Vivien Casagrande, a professor of cell biology and psychology at
Developing Intellectual Entrepreneurship
Kate Devine | Mar 4, 2001 | 4 min read
Doctoral programs do not adequately prepare students for the future. So says the recent study funded by the Pew Charitable Trusts, "At Cross Purposes: What the Experiences of Today's Doctoral Students Reveal about Doctoral Education."1 To solve this problem the University of Texas, which produces the largest number of Ph.D.s annually, established a professional development program (www.utexas.edu/ogs/development.html). Initiated in 1997, the mission of the University of Texas at Austin Intellect
Telomere Without End, Amen: Looking Into Longevity with Telomere Detection Kits
Laura Defrancesco | Mar 29, 1998 | 10 min read
Date: March 30, 1998 Author: Laura DeFrancesco T he excitement over telomerase continues to mount as evidence accumulates that makes the connection between telomere length and cell lifespan likely to be more than a coincidence. The most recent findings show that the age span of cultured cells, normally limited to around 50 cell doublings--the so-called Hayflick limit, named for the scientist who first observed that the lifespan of cultured cells was finite--can be more than doubled by transfec
