The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.
Mapping Subtelomeres
Ricki Lewis | Oct 14, 2001 | 4 min read
In genetics, certain terms sometimes mask what scientists do not yet understand, such as "junk DNA." Similarly, the chromosomal regions just proximal to the tips--the subtelomeres--have been dubbed "buffers," ill-defined DNA sequences that somehow support the telomeres, which control the cell cycle and cellular aging. A team of researchers from the Wistar Institute in Philadelphia, the University of California, Irvine, and John Radcliffe Hospital in Oxford, UK, has used single-copy sequences in

Targeting Antibiotic-Resistant Bacteria with CRISPR and Phages
Anna Azvolinsky | May 18, 2015 | 3 min read
Researchers develop a CRISPR-based, two-phage system that sensitizes resistant bacteria to antibiotics and selectively kills any remaining drug-resistant bugs. 
Human Genes: How Many?
Tom Hollon | Oct 14, 2001 | 6 min read
Counting human genes ought to be straightforward. Tracking telltale signs--motifs for promoters, translation start sites, splice sites, CpG islands--gene counters must by now be mopping up, finalizing chromosomal locations of every human gene already known, and predicting whereabouts of all the rest. Insert one human genome sequence, turn the bioinformatics crank, and genes gush out like a slot machine jackpot, right? "No, no, no," says Bo Yuan, of Ohio State University, having a laugh over th

He would dump them on his desk and begin to prepare them for microRNA sequencing, hoping to determine wh
60 Members Elected to NAS
Barry Palevitz | Jun 25, 2000 | 6 min read
Editor's Note: On May 2, the National Academy of Sciences announced the election of 60 new members and 15 foreign associates from nine countries in recognition of their distinguished and continuing achievements in original research. Nearly half of the new members are life scientists. In this article, The Scientist presents photographs of some of the new members and comments from a few of them on their careers and on past and current research. A full directory of NAS members can be found online a
Assays Galore

Courtesy of BD Biosciences Pharmingen  COLOR CODING: Multiplexed bead-based assays, like BD Biosciences' Cytometric Bead Array (shown), test for multiple analytes in a single vial. The key is in the colors: one hue indicates the bead ID, and the intensity of the second, how much protein has been captured. In today's fast-paced research environment, technologies for speedy, cost-efficient analyses reign supreme. As part of this general trend, techniques for multiplexing, that is, simultan
